EXAMPLES OF IMPLEMENTATION

[0085] It is understood that individual examples of the implementation of the invention are presented to illustrate and not to limit. Using no more than routine experimentation, any knowledgeable professionals may find or be able to find a number of equivalents to the specification of the implementation of the invention which are not explicitly described here. Such equivalents are meant to fall within the scope of the following patent claims. Any topological or kinematic modification of this kind of hockey skatemill, including necessary design, choice of materials and design layout may not be problem, therefore these features have not been dealt with in detail. In the following examples one can find individual descriptions of different manners of implementation that use an electric motor to drive the skatemill. It is understood that in an analogous way it is possible to use any undisclosed drive unit to drive the skatemill and smoothly control its direction and speed of rotation.

Example 1

[0086] This example of a specific implementation of the invention describes a structure design of the integrated multi-purpose hockey skatemill with its control/management system for the individual training and testing of the skating and hockey skills, in a maximum operational assembly modified for a hockey training center as depicted in the enclosed FIG. 1. It consists of a barrier-free work area made up from a stationary area of artificial ice 1 and a movable built-in skatemill belt 2 as depicted in the enclosed FIG. 3. Materials such as FunICE, Scan_ice, Xtraice, EZ-Glide etc. can be used as an artificial ice 1. The movable skatemill belt 2 comes as the so-called endless belt with its surface fitted with a material made of artificial ice. The skatemill belt is placed on two rotating load-bearing drums 2c and 2d. As shown in FIG. 14, 2c is a drive drum and 2d is a powered drum that are placed in ball bearings and on a shared support frame that is not depicted. The movable skatemill belt 2 is supported by solid metal beams 2a, as depicted in FIG. 13. These beams of the movable skatemill belt 2 touch it with nonmoving sliding surfaces 2b. On the boundary line defining a front side of the work area, extending the longitudinal axis of the movable skatemill belt 2, there is a hockey goal structure 11 with sensors 11a detecting puck hits on the target zones. The sensors are connected to the electronic control system 9 via signal or data channels (metallic or wireless) 10, as depicted in FIG. 11. The sensor 11b monitoring verbal announcements of a hockey player, in this case an acoustic microphone, is located on a head-mount holder. It is connected to the electronic control system 9 via signal or data channels (metallic or wireless) 10, as depicted in FIG. 11. Above the movable skatemill belt 2 is a top-hung safety restraint system 3 for skaters or hockey players, as depicted in FIG. 5. This comprises a personal harness system 3a, e.g. a full-body harness with a dorsal and adjustable straps 3b connected via carabiner clips 3c on one side to the skater's full body harness and on the other to the anchoring point 3d attached to a safety switch 3e that will stop the skatemill belt 2 from moving if pulled by the weight of the skater. The safety switch 3e slides on a horizontal guide rod 3f that is anchored on the first brackets 3g. Above the movable skatemill belt 2 is also a top-hung stabilization system 4 for skaters or hockey players, as depicted in FIG. 6. The system consists of two top-hung vertical beams 4a with the foldable horizontal handrails 4b, such as handlebars. The position of the beams, i.e. height from the surface of the work area, may be adjusted. The handrails 4b may be tipped into an upright position in parallel with the vertical beams. The vertical beams 4a are top-hung on the second brackets 4c over the side of the movable and stationary lines of the work surface so that the vertical beams 4a with unfolded handrails 4b do not interfere with the space above the skatemill 2. First brackets 3g and second brackets 4c may be combined into one common bracket. The suspension mechanism of the stabilization system 4 allows to tilt the vertical beams 4a with the handrails 4b facing up to the horizontal position as high as 2.2±0.1 m. At places defined by the intersections of the semicircular line, whose central point is identical with the center of the movable skatemill belt 2 and whose radius is 4.5±0.5 m, the arms of the angle from 70° up to 90° and with the vertex in the center of and symmetrical to the longitudinal axis of the movable skatemill belt 2, there are placed optical signalization/display elements 5 (left and right) hanging from the tiltable or vertically sliding brackets 5a. The middle optical signalization/display element 5 is located on the bracket 5a fitted on a line that is defined by the longitudinal axis of the movable skatemill belt 2, 6 ±1 m from its center. The suspension mechanism of the bracket 5a of the optical signalization/display element 5 allows to tilt the bracket a together with the optical signalization/display element 5 upwards to a horizontal position as high as 2.2±0.1 m. The optical signalization/display elements 5 are connected to the electronic control system 9 via signal or data (metallic or wireless) channels 10, as depicted in FIG. 7. On the edges of the training zone and in vertical planes passing through the longitudinal and transverse axes of the movable skatemill belt 2, there are digital optical scanning cameras 6 fitted_on brackets 6a and connected to the electronic control system 9 via signal or data (metallic or wireless) channels 10, as depicted in FIG. 8. On the border line defining the front side of the work area, there are two puck feeders 7, as depicted in FIG. 9. The feeders are likewise connected to the electronic control system 9 via signal or data (metallic or wireless) channels 10. On the two top-hung tiltable or vertically sliding brackets 8a, or on firm brackets (only in the case of the brackets located in the area behind the movable skatemill belt 2), and in the axis of the movable skatemill 2, 2.5±0.25 m from its center, there is a system measuring tensile/compressive forces by means of piezoelectric or tensiometric force-measuring sensors 8 as depicted in FIG. 10. Strength effect (tensile or compressive) exerted by a skater or a hockey player on the front and/or back sensor 8 is carried out by means of the front and/or back fibre handle 8b (tensile force) or solid rod (tensile and/or compressive force). Vertical position of the force sensor 8 may be set up within the range of 0.8 to 1.4 m. The suspension mechanism of the bracket 8a of the force sensor makes it possible to tilt the sensor's bracket 8a together with the force sensor 8 upwards to a horizontal position as high as 2.2±0.1 m. The force sensors 8 are connected to the electronic control system 9 via signal or data (metallic or wireless) channels 10. The movable skatemill belt 2 is powered by a drive unit 2e which is in all disclosed examples as shown in FIGS. 13a-13c a 3-phase asynchronous electric motor. The transmission connection between the electric motor 2e and the drive drum 2c of the movable skatemill belt 2 may be carried out in several alternative ways. The first alternative, as depicted in FIG. 13, represents a direct drive of the drive drum 2c of the movable skatemill belt 2, with the so-called drum electric motor 2e being directly built in the drive drum 2c itself. The second alternative, as depicted in FIG. 13, shows an example where a drive drum 2c of the movable skatemill belt 2 is powered by a propulsion electric motor 2e by means of a belt or chain transmission 2f. The third alternative, as depicted in FIG. 13, shows an example where a propulsion electric motor 2 powers a drive drum 2c of the movable skatemill belt 2 by means of a transmission 2g with the hard gear ratio. The propulsion electric motor 2e is in all cases a 3-phase asynchronous electric motor whose direction and rotational speed are continuously managed through a frequency converter 13 controlled by the electronic control system 9, as depicted in FIG. 17. Emergency stop of the movable skatemill belt 2 in the event of a skater's a or a hockey player's fall is secured by a safety isolating switch disconnecting power supply for the propulsion electric motor 2e in the block of the power supply 14 which is directly managed by the switch of safety harness 3e, as depicted in FIG. 17. The solid metal support beams featuring stationary sliding surfaces 2a are hollow and a cooling medium is pushed into the hollows of the solid beams which cools the solid beams 2a down. For that purpose, each support beam features one or several inlets 2h through which a liquid or gaseous cooling medium 2h-1 is let into the hollows in the support beams, as shown in the FIGS. 13 and 14. At the same time, each of the support beams has one or several outlets 2i through which the heated cooling medium 2i-1 is let out from the hollows in the support beams 2a, as shown in the FIGS. 13 and 14. The hollows in the support beams 2a come in any shape, cross-sectional area, dimensions, number and in the case of more than one hollow they may have any mutual position and as for the inlets 2h and outlets 2i, they are positioned on the support beams in any number and in any random places. Moreover, they may come in any shape, cross-sectional area, dimensions and any mutual position. Cooling medium 2h-1 is pushed into the support beams 2a, in the case of the liquid cooling medium, by means of an undisclosed pump or pumps and in the case of the gaseous cooling medium by means of a compressor or compressors and/or a fan or fans through an undisclosed inlet pipeline or pipelines. The cooling medium 2i-1 gets heated as it passes through the hollows of the support beams 2a and is let out by means of an undisclosed outlet pipeline or pipelines through an undisclosed radiator into an undisclosed cooling medium storage tank.

[0111] It is possible to place two detachable laser markers 12 on optional mounts 12a on the stationary area of the artificial ice 1 facing the front border of the movable skatemill belt in order to define the width of the skate track, as depicted in FIG. 12.

[0112] Alternatively, there is a solution for the integrated multi-purpose hockey skatemill in combination with a system for the individual training and testing of the skating and hockey skills as depicted in the FIG. 2 where the electronic control electronic control system 9 is connected to a data LAN network 9a. This allows to manage or monitor functions of the skatemill remotely through the so-called control/management console 9d, i.e. by means of different networking equipment that makes it possible to implement the operator console comprising at least a display unit, e.g. graphic or character display device and a data input apparatus, e.g. a keyboard, touchpad or mouse or it is possible to remotely control or monitor the skatemill's functions by another automatic system. If the LAN data network 9a is a communication gate or a firewall 9b connected to the Internet 9c, it is possible to remotely control or monitor the skatemill through a control/management console 9d connected via the Internet.

Example 2

[0113] The integrated multi-purpose hockey skatemill with a system for the individual training and testing of the skating and hockey skills described in Example 1 can be used in combination with the functional block 9a-11 of the Shooting at the light of the electronic control system 9 for automated management of the movement of the movable skatemill belt 2, for automated management of the optical signalization/display elements 5 and for automated recording of signals from the sensors 11a detecting impacts on the target zones during the “Shooting at the light” training on the skatemill. Integrated multi-purpose hockey skatemill control (method) by means of the electronic control system 2 featuring the functional block 9a-11 of the Shooting at the light while performing the “Shooting at the light” training is implemented by the configuration prescription of the microcontroller 92 of this functional block is shown in the FIG. 19. Signal connections between the integrated multi-purpose ice hockey skatemill and electronic control system 2 are depicted in FIG. 17.

[0114] In such case, i.e. during the Shooting at the light training, the electronic control system 9 of the skatemill controls a frequency converter 13, by means of which it manages (switches on) the movement of the movable skatemill belt 2 so that it moves at a (set) speed. It also controls the display of light or optical signals S.sub.1-S.sub.5 on a flat display of the middle optical signalization/display element 5 in the zones Z.sub.1=“LEFT TOP CORNER”, Z.sub.2=“RIGHT TOP CORNER”, Z.sub.3=“BOTTOM CENTER”, Z.sub.4=“LEFT BOTTOM CORNER” and Z.sub.5=“RIGHT BOTTOM CORNER” in any given or random order. A hockey player skating on the running skatemill belt 2 reacts to these light stimuli by shooting a puck into a given target zone Z defined for instance on the frontal plane of a hockey goal structure 11. Unless the hockey player shoots the puck within certain time “t.sub.signal”, the application will evaluate it as a failed attempt. After the test, the electronic control system 9 of the skatemill will stop the skatemill belt 2 from moving. The total number of signals sent out by the application N=ΣN.sub.q, q=1-5 and the count of impacts on the given target zone n=Σn.sub.q, q=1-5 achieved by the hockey player within a given time are recorded in an automated or non-automated way. At the same time these data represent the test result. By setting up the so-called mapping vector of signals in any other way than in the “1:1” scheme represented by incidence rate of signals and target zones: S.sub.1->Z.sub.1, S.sub.2->Z.sub.2, S.sub.3->Z.sub.3, S.sub.4->Z.sub.4 a S.sub.5->Z.sub.5, it is possible to set up any other incidence (mapping) of signals S and target zones Z, e.g. S.sub.1->Z.sub.2, S.sub.2->Z.sub.1, S.sub.3->Z.sub.3, S.sub.4->Z.sub.4 a S.sub.5=Z.sub.5, or e.g. S.sub.1->Z.sub.4, S.sub.2->Z.sub.5, S.sub.3->Z.sub.3, S.sub.4->Z.sub.1 a S.sub.5->Z.sub.2 etc., thus making it possible to adjust the level of training difficulty to the needs of hockey players. Automated detection of impacts on the target zones is provided by the electronic control system 9 by means of mechanical contact or piezoelectric or contactless optical or inductive impact detection sensors 11a placed in the target zones Z.sub.1-Z.sub.5 of a hockey goal structure 11 located in front of the movable skatemill belt 2 on the border line defining the front side of the work area in the extension of the longitudinal axis of the movable skatemill belt 2.

[0115] As a variant, during the Shooting at the light training, the electronic control system 9 of the skatemill can also manage puck feeders 7 in such a way that their (puck feeders) operation is coordinated with the course of the Shooting at the light training, i.e. actions of the puck feeders 7 (shooting of a puck) are time-synchronized with the expected moment of a hockey player's launching a shot. All this happens following the display of a light navigation symbol.

Example 3

[0116] The integrated multi-purpose hockey skatemill with a system for the individual training and testing of the skating and hockey skills, as described in Example 1, can be used in a similar way to the previous example in combination with the functional block 9a-12 of the Watch the light of the electronic control system 9. It can be used for automated management of the movement of the skatemill belt 2 for automated management of optical signalization/display elements 5 as well as for automated recording of signals from the detection sensors 11a picking up the impacts on the target zones and an acoustic microphone, which is a sensor 11b monitoring/recording verbal messages of a hockey player during the Watch the light training on the integrated multi-purpose hockey skatemill. Integrated multi-purpose hockey skatemill control (method) by means of the electronic control system 9 featuring the functional block 9a-12 of the Watch the light while performing the “Watch the light” training is implemented by the configuration prescription of the microcontroller 92 of this functional block is shown in the FIG. 20. Signal connections between the integrated multi-purpose ice hockey skatemill and electronic control system 9 are depicted in FIG. 17.

[0117] In such case, i.e. during the Watch the light training, the electronic control block 9 of the skatemill controls a frequency converter 13, by means of which it manages (switches on) the movement of the movable skatemill belt 2 so that it moves at a (set) speed. It also controls the display of light signals Y={0-9|00-99|aA-zZ|.square-solid..circle-solid..box-tangle-solidup.} (i.e. numbers and digits, alphabetic characters and simple geometric figures) apart from the central display element 5, also on the display elements positioned in the LEFT zone and in the RIGHT zone of a hockey player's peripheral vision in any given or random order. A hockey player who is skating on the moving skatemill belt 2 responds to these light stimuli via identifying and verbalizing a symbol and/or doing something else, e.g. shooting at the predetermined target zone. After the test, the electronic control system 9 stops the movement of the skatemill belt 2. The total number of the signals sent by the application N=ΣN.sub.q, q=1-5 and the number of correctly identified symbols by a hockey player within the time limit “t.sub.display” n=Σn.sub.q, q=1-5 are logged automatically or non-automatically. These data represent the test results. Automated detection of the correctly identified symbols in the case of their verbalization by a hockey player is provided by the electronic control system 9 using a speech recognition system. An acoustic microphone 11b monitoring verbal messages of a hockey player is in this case placed on a protective helmet of the hockey player or on the headset holder. Alternatively, if the hockey player responds to the visualized signals by shooting to the designated zones, the automated detection of the impacts on the target zones is provided by the electronic control system 9 by means of mechanical contact or piezoelectric or the contactless optical and inductive sensors fitted in the target zones of a 11 hockey goal Z.sub.1-Z.sub.5 placed in front of the skatemill belt 2 on the borderline defining the front side of the work area in the extension of the longitudinal axis of the skatemill belt 2.

Example 4

[0118] The integrated multi-purpose hockey skatemill with a system for the individual training and testing of the skating and hockey skills, as described in Example 1, can be used in a similar way to the previous example in combination with the functional block 9a-13 of the Exercise according of the electronic control system 2. It can be used for automated management of the movement of the skatemill belt 2 and for automated management of optical signalization/display elements 5 during the Exercise according to the pattern training on the integrated multi-purpose hockey skatemill. Integrated multi-purpose hockey skatemill control (method) by means of the electronic control system 2 featuring the functional block 9a-13 of the Exercise according to the pattern while performing the “Exercise according to the pattern” training is implemented by the configuration prescription of the microcontroller 92 of this functional block is shown in the FIG. 21. Signal connections between the integrated multi-purpose ice hockey skatemill and electronic control system 9 are depicted in FIG. 17.

[0119] During the Exercise according to the pattern training, on one or more display elements, the electronic control system 9 of the skatemill shows a recorded digital video footage “Sample( )” of the practice or exercise a skater or a hockey player on the skatemill should carry out. After viewing the video recording of the practice or exercise, the electronic control system 9, by means of a frequency converter 13, controls (switches on) the movement of the skatemill belt 2 so that it could move at the default (set) speed. After the given time “Tduration” planned to carry out the training or exercise has elapsed, the electronic control system stops the movement of the skatemill belt 2.

Example 5

[0120] The integrated multi-purpose hockey skatemill with a system for the individual training and testing of the skating and hockey skills, as described in Example 1, can be used in a similar way to the previous example in combination with the functional block 9a-14 of the Live view of the electronic control system 9. It can be used for automated management of the movement of the skatemill belt 2 and for automated management of optical signalization/display elements 5 during the Live view training on the integrated multi-purpose hockey skatemill. Integrated multi-purpose hockey skatemill control (method) by means of the electronic control system 9 featuring the functional block 9a-14 of the Live view while performing the “Live view” training is implemented by the configuration prescription of the microcontroller 92 of this functional block is shown in the FIG. 22. Signal connections between the integrated multi-purpose ice hockey skatemill and electronic control system 9 are depicted in FIG. 17.

[0121] During the Live view training, by means of a frequency converter 13 the electronic control system 9 of the skatemill controls (switches on) the movement of the skatemill belt 2 so that it could move at the default (set) speed. The electrobic control system also manages the creation and temporary storage of digital video recordings (the front “StreamRecord1” and the side “StreamRecord2”) and a delayed (with a delay “Tdelay”=<5 s-15 min>) presentation of the created video recordings of a prior exercise or training performed by a skater or a hockey player on the skatemill belt 2. If the delay “Tdelay” is set at the same time as the duration of an exercise (training), it is possible for the skater or the hockey player to watch his very own just finished exercise or training in order to realize their potential shortcomings committed at the training.

Example 6

[0122] The integrated multi-purpose hockey skatemill with a system for the individual training and testing of the skating and hockey skills, as described in Example 1, can be used in a similar way to the previous example in combination with the functional block 9a-15 of the Skating posture of the electronic control system 9. It can be used for automated management of the movement of the skatemill belt 2 for automated management of optical signalization/display elements 5 as well as for the optical scanning cameras 6 during the Skating posture test on the integrated multi-purpose hockey skatemill. Integrated multi-purpose hockey skatemill control (method) by means of the electronic control system 9 featuring the functional block 9a-15 of the Skating posture while performing the “Skating posture” training is implemented by the configuration prescription of the microcontroller 92 of this functional block is shown in the FIG. 23. Signal connections between the integrated multi-purpose ice hockey skatemill and electronic control system 9 are depicted in FIG. 17.

[0123] During the Skating posture test, by means of a frequency converter 13, the electronic control system 9 of the skatemill controls (switches on) the movement of the skatemill belt 2 so that it could move at the default (set) speed. The electronic control system also manages the creation and storage of digital video recordings of the course of the skating performed by a skater or a hockey player on the movable skatemill belt from the front (StreamRecord1) and the side (StreamRecord2) views. After the test, i.e. after the time “T.sub.PERIOD” has elapsed, the electronic control system 9 stops the movement of the skatemill belt 2. Following that, canonical segments are added to the digital video recordings, e.g. in MPEG4 format, via video editing tools in either automated or non-automated way. The canonical segments represent positions of the lower extremities or their parts, mutual positions and kinematic movement patterns whose canonical segments are further analyzed in order to identify shortcomings and/or optimize skating skills of a skater or a hockey player.

Example 7

[0124] The integrated multi-purpose hockey skatemill with a system for the individual training and testing of the skating and hockey skills, as described in Example 1, can be used in a similar way to the previous example in combination with the functional block 9a-16 of the Skating Power of the electronic control system 9. It can be used for automated management of the movement of the skatemill belt 2 and for automated measuring and recording of the tensile or compressive force exerted by a skater or a hockey player during the Skating Power test on the integrated multi-purpose hockey skatemill. Integrated multi-purpose hockey skatemill control (method) by means of the electronic control system 9 featuring the functional block 9a-16 of the Skating Power while performing the “Skating Power” training is implemented by the configuration prescription of the microcontroller 92 of this functional block is shown in the FIG. 24. Signal connections between the integrated multi-purpose ice hockey skatemill and electronic control system 9 are depicted in FIG. 17.

[0125] During the Skating Power test, by means of a frequency converter 13, the electronic control system 9 of the skatemill controls the speed of the skatemill belt 2 so that it could move at required speeds in order to determine a skater's or a hockey player's speed performance profile. The electronic control system also controls measuring and recording of data on values of the tensile or compressive force exerted by a skaters or hockey players during the test.

[0126] The speed performance profile for a skater or a hockey player is laid as an 8-element sequence of the values of power (expressed in watts) exerted by a skater or a hockey player while skating on a level surface facing forward in eight different reference skating speeds, as follows: 15.0-16.5-18.0-19.5-21.0-22.5-24.0-25.5 km/h. Power given by skater is determined by the method described below.

[0127] From the measured tensile or compressive forces respectively, one measures the power attained by a skater or a hockey player in each of the eight reference skating speeds “v.sub.stride” 15.0-16.5-18.0-19.5-21.0-22.5-24.0-25.5 km/h by relation:

[00004]$P=1/8\underset{k=1}{\overset{8}{.Math.}}{F}_k.Math.v_{\mathrm{stride}}\left[W,N,{\mathrm{ms}}_{-1}\right]$

in which “P” stands for performance exerted by a skater or a hockey player, “k” is the serial number of a skating stride in an 8-step series and “F.sub.k” represents the maximum tensile or compressive forces exerted by a skater or a hockey player as measured by the sensor for measuring the force in the skating stride “k”. Between the respective tests, i.e. between the tests at the reference speeds 15.0-16.5-18.0-19.5-21.0-22.5-24.0-25.5 km/h are included relaxation intervals of not less than 120 seconds.

Example 8

[0128] The integrated multi-purpose hockey skatemill with a system for the individual training and testing of the skating and hockey skills, as described in Example 1, can be used in a similar way to the previous example in combination with the functional block 9a-17 of the Skating endurance of the electronic control system 9. It can be used for automated management of the movement of the skatemill belt 2 and for automated measuring and recording of the tensile or compressive force exerted by a skater or a hockey player during the Skating endurance test on the integrated multi-purpose hockey skatemill. Integrated multi-purpose hockey skatemill control (method) by means of the electronic control system 9 featuring the functional block 9a-17 of the Skating endurance while performing the “Skating endurance” training is implemented by the configuration prescription of the microcontroller 92 of this functional block is shown in the FIG. 25. Signal connections between the integrated multi-purpose ice hockey skatemill and electronic control system 9 are depicted in FIG. 17.

[0129] During the Skating endurance test, by means of a frequency converter 13, the electronic control system 9 of the skatemill controls (switches on) the movement of the skatemill belt 2 so that it could move at a given (set) speed “v.sub.strideMAX” in order to determine a skater's or a hockey player's endurance performance profile and fatigue index. The electronic control system 9 also controls measuring and recording of data on values of the tensile or compressive force exerted by skaters or hockey players during the test.

[0130] The endurance performance profile is determined as the 6-element sequence of average values of power (P.sub.[0-5], P.sub.[5-10], P.sub.[10-15], P.sub.[15-20], P.sub.[20-25], P.sub.[25-30] expressed in watts) exerted be a skater while skating on a level surface facing forward in 6 different time intervals: <0-5 s>, <5-10 s>, <10-15 s>, <15-20 s>, <20-25 s>, <25-30 s> by the relations:

[00005]$\begin{array}{cc}{P}_{\left[0-5\right]}=v_{\mathrm{strideMAX}}.Math.1/5{\int }_{t=0}^5{F}_{\mathrm{stride}}\left(t\right)\mathrm{dt}& \left[W,{\mathrm{ms}}_{-1},N\right]\\ P_{\left[5-10\right]}=v_{\mathrm{strideMAX}}.Math.1/5{\int }_{t=5}^{10}{F}_{\mathrm{stride}}\left(t\right)\mathrm{dt}& \left[W,{\mathrm{ms}}_{-1},N\right]\\ P_{\left[10-15\right]}=v_{\mathrm{strideMAX}}.Math.1/5{\int }_{t=10}^{15}{F}_{\mathrm{stride}}\left(t\right)\mathrm{dt}& \left[W,{\mathrm{ms}}_{-1},N\right]\\ P_{\left[15-20\right]}=v_{\mathrm{strideMAX}}.Math.1/5{\int }_{t=15}^{20}{F}_{\mathrm{stride}}\left(t\right)\mathrm{dt}& \left[W,{\mathrm{ms}}_{-1},N\right]\\ P_{\left[20-25\right]}=v_{\mathrm{strideMAX}}.Math.1/5{\int }_{t=20}^{25}{F}_{\mathrm{stride}}\left(t\right)\mathrm{dt}& \left[W,{\mathrm{ms}}_{-1},N\right]\\ P_{\left[25-30\right]}=v_{\mathrm{strideMAX}}.Math.1/5{\int }_{t=25}^{30}{F}_{\mathrm{stride}}\left(t\right)\mathrm{dt}& \left[W,{\mathrm{ms}}_{-1},N\right]\end{array}$

in which “P.sub.[ ]” is average power exerted by a skater or a hockey player within the measured 5-second interval and “F.sub.stride(t)” is a function that expresses time dependency of the tensile or compressive forces exerted by a skater or a hockey player as measured by the sensor for measuring the force in the measured 5-second interval.

[0131] Fatigue index of a skater or a hockey player is the extent (size) of the power loss exerted by a skater or a hockey player at the start, in time interval <0-5 s> and at the end, in time interval <25-30 s> of the Skating endurance test. It is expressed in % of the extent of power loss and the average performance attained by a skater in the interval <0-5 s> by the relation in %.

[00006]${\mathrm{INDEX}}_U=\frac{p_{\left[0-5\right]}-p_{\left[25-30\right]}}{p_{\left[25-30\right]}}=.Math.100\%\left[\%\right]$

Example 9

[0132] The integrated multi-purpose hockey skatemill with a system for the individual training and testing of the skating and hockey skills, as described in Example 1, can be used in a similar way to the previous example in combination with the functional block 9a-18 of the Skating power and endurance of the electronic control system 9. It can be used for automated management of the movement of the skatemill belt 2 and for automated measuring and recording of the tensile or compressive force exerted by a skater or a hockey player during the Skating power and endurance test on the integrated multi-purpose hockey skatemill. Integrated multi-purpose hockey skatemill control (method) by means of the electronic control system 9 featuring the functional block 9a-18 of the Skating power and endurance while performing the “Skating power and endurance” training is implemented by the configuration prescription of the microcontroller 92 of this functional block is shown in the FIG. 26. Signal connections between the integrated multi-purpose ice hockey skatemill and electronic control system 9 are depicted in FIG. 17.

[0133] During the Skating power and endurance test, by means of a frequency converter 13, the electronic control system 9 of the skatemill controls the speed of the skatemill belt 2 so that it could move at required speeds. The electronic control system also controls measuring and recording of data on values of the tensile or compressive force exerted by skaters or hockey players during the test in order to determine a skater's or a hockey player's speed performance profile, as described in Example 7 and then to continually (within one test) determine the endurance performance profile and fatigue index of a skater or a hockey player, as described in Example 8.

Example 10

[0134] The integrated multi-purpose hockey skatemill with a system for the individual training and testing of the skating and hockey skills, as described in Example 1, can be used in a similar way to the previous example in combination with the functional block 9a-19 of the Skater's aerobic skills of the electronic control system 9. It can be used for automated management of the movement of the skatemill belt 2 during the Skater's aerobic skills test on the integrated multi-purpose hockey skatemill. Integrated multi-purpose hockey skatemill control (method) by means of the electronic control system 9 featuring the functional block 9a-19 of the Skater's aerobic skills while performing the “Skater's aerobic skills” training is implemented by the configuration prescription of the microcontroller 92 of this functional block is shown in the FIG. 27. Signal connections between the integrated multi-purpose ice hockey skatemill and electronic control system 9 are depicted in FIG. 17.

[0135] During the Skater's aerobic skills test, by means of a frequency converter 13, the electronic control system 9 of the skatemill controls the movement of the skatemill belt 2 either_in autonomous or coupled mode in order to determine an aerobic performance profile by an external spirometric or cardiopulmonary monitor. The external spirometric or cardiopulmonary monitor is connected to the universal communication interface of the electronic control system 9 of the skatemill via own signal or data cable. Connection between the external spirometric or cardiopulmonary monitor and the electronic control system 9 is not included in the technical solution of the skatemill.

[0136] When in the autonomous mode of the Skater's aerobic skills test, the electronic control system 9 controls the movement of the skatemill belt 2 through a frequency converter 13 in such a way that it starts to move at a speed “v.sub.START” and then it incrementally increases the speed of the skatemill belt in the I. speed zone by a 2 km/h stride until it reaches II. speed zone. Once in the II. speed zone, the speed incrementally increases each minute by a 1 km/h stride until the end of the test. The test itself finishes either after 1 minute of the maximum speed of the skatemill belt “v.sub.skateMAX” or in any given moment on request of the skater or hockey player. After taking the test, the electronic control system 9 of the skatemill stops the movement of the skatemill belt 2.

[0137] In both cases, the result of the test is a data set on aerobic performance profile recorded by an external spirometric or cardiopulmonary monitor.

Example 11

[0138] This example of a particular implementation of the technical solution describes a “not shown” variant design solution for the integrated multi-purpose hockey skatemill with a system for the individual training and testing of the skating and hockey skills in a modification meant for a hockey training center in the enclosed FIG. 1 whose basic features are sufficiently described in Example 1. The difference in design is that instead of the electronic control system 9, a distinct electronic computing system, a computer equipped to perform the same control, logic and computing functions as those carried out by the electronic control system 9, as described in Example 1.

[0139] Another “not shown” example of the technical solution that is described sufficiently in basic features in Example 1 is the use of multiple electronic computing systems, computers used to perform the same control, logic and computing functions as those carried out by the electronic control system 9, as described in Example 1.

Example 12

[0140] This example of a particular implementation of the technical solution describes a variant design solution for the integrated multi-purpose hockey skatemill with a system for the individual training and testing of the skating and hockey skills in a modification meant for a hockey training center whose basic features are sufficiently described in Example 1 and shown in the FIG. 15. The difference in design is that this time both movable skatemill belts 2 share one common pair of puck feeders 7. At the same time they share one common stationary area of the artificial ice 1, only that each of the moving skatemill belts 2 has its own group of the signalization/display elements 5 its own group of the digital optical scanning cameras 6 as well as its own group of the tensile/compressive force sensors 8.

[0141] Alternatively, the FIG. 16 depicts a solution where the two movable skatemill belts 2 share one common pair of puck feeders 7 and one common stationary area of the artificial ice 1. Both of the movable skatemill belts 2 also share a common group of signalization/display elements 5 but only one of the movable skatemill belts 2 is equipped with the digital optical scanning cameras 6. Another “not shown” example of the technical solution, in comparison with the solution depicted in the FIG. 16, is in a modification where only one movable skatemill belt 2 is equipped with the tensile/compressive force sensors 8.

INDUSTRIAL APPLICATION

[0142] The invention is intended especially for the individual training and testing of hockey players and other athletes who perform their activities on ice and use skates.
