A method for training athletes is disclosed. The method comprises: calculating an athletic signature for an athlete comprising normalized values for the concentric net vertical impulse (CON-IMP), the average eccentric rate of force development (ECC-RFD), and the average vertical concentric force (CON-VF) for the athlete; analyzing the athletic signature; and assigning at least one training block to the athlete based on the analysis of the athletic signature.

A strap spring trampoline includes a trampoline frame having an upper horizontal trampoline frame and a lower horizontal trampoline frame. A trampoline bed is extended across the upper horizontal trampoline frame. A strap connection is formed on the trampoline bed that connects the trampoline bed to a tension strap. A spring is connected to the tension strap and the lower horizontal trampoline frame. The spring is preferably helical. The trampoline leg rigidly connects between the upper horizontal trampoline frame and the lower horizontal trampoline frame. The upper horizontal trampoline frame has a horizontal extension, and the horizontal extension further includes a flat section. A spool sleeve fits over the upper horizontal trampoline frame, and a tension strap rides over the spool sleeve when the tension strap moves over the upper horizontal trampoline frame. A right collar and a left collar fit together and retain the spool sleeve.

A method of detecting and calculating height of a jump performed by an individual including detection of a reception subsequent to the jump is described. The detection includes a sub-step of detecting a pressure spike of amplitude greater than a first threshold amplitude, within pressure measurements provided by a pressure sensor embedded aboard a watch worn on the wrist of the individual. Also described is calculation of a height of the jump by differencing a starting altitude corresponding to a last stable pressure measured before the pressure spike and a finishing altitude corresponding to a first stable pressure measured after the pressure spike via the pressure sensor, a stable pressure being defined as a pressure whose variations do not exceed 0.1 hectopascals for at least 2 seconds.

An ideal target weight training recommendation system and method ascertains a user's ideal target weight with a user-data algorithm that computes a strength coefficient based on weight repetitions. The user generates initial completed repetitions until the muscles fatigue. A baseline strength value is calculated with the initial completed repetitions and a baseline strength coefficient. A resistance value of the free weights divided by the baseline strength coefficient, produces the baseline strength value. The baseline strength value is used in calculating ideal target weight values. A user-data defined y-intercept approximate functions. Each y-intercept approximate functions involving user-selected desired target repetition values. The user manipulates a resistance structure associated with the ideal target weight values. The ideal target weight values are rounded to the nearest whole number. The user-selected desired target repetition values generate second completed repetition values for subsequent sets. This causes the strength curve to automatically adapts to strength progression.

A hurdle system and method. The hurdle system has a telescoping interior arm and a non-telescoping exterior arm. The telescoping interior arm has spaced-apart cylindrical apertures that allow the height of the telescoping interior arm to be locked. A hurdle cross bar support fixedly attaches to a distal end of the telescoping interior arm. A hurdle cross bar is supported by the hurdle cross bar support in a parallel relationship. A bottom cross bar is placeable on the ground as support base for the hurdle. A proximal end of the non-telescoping exterior arm and the bottom cross bar are fixedly attached. A pair of bottom cross bar extensions extend from opposite ends of the bottom cross bar to provide additional stability. A position adjustable counterweight at the bottom cross bar maintains the hurdle in an upright position.

A frame structure for a mini trampoline includes at least three nodes and at least three elongate internodes, as well as a multiplicity of legs. In each case, two of the internodes are assigned to each other with end portions and are connected rigidly to each other via one of the nodes such that a closed frame lying substantially in one main plane is formed. Each leg is fastened directly to one of the nodes.

A pair of electronic shoe insoles aids an individual with peripheral neuropathy in walking without falling, despite the user having little or no sensation in her feet. Each insole uses a number of pressure sensors and provides various forms of biofeedback to the user such as auditory, haptic, and vibratory feedback which corresponds to the position of the user's foot on the ground. Vibration feedback is provided through vibration motors disposed against the soles of the user's feet at selected locations which correspond to locations of pressure sensors. This allows for direct neural stimulation of the sole of the foot at three biomechanically appropriate locations. Auditory and haptic feedback are provided through auxiliary devices that the user wears on appropriate parts of the body. Biofeedback transmitted through these mechanisms would correspond to change in foot position as detected by the pressure sensors. The shoe insoles may provide one or more of these forms of feedback, and other types of feedback may be provided by output devices as well. An embedded microcontroller wirelessly connected to a computer, tablet or phone permits an individual to monitor gait performance and to adjust numerous parameters of this biofeedback mechanism, such as time delays and strength of vibration or audio feedback. The device may also include a driving mode in which small variations of pressure on the gas pedal would be conveyed to the user through haptic and auditory feedback, thereby allowing the user to drive.

A jumper apparatus may include a base, a set of poles, a pneumatic tube and a cap. Each of the poles extend upwardly from the base and circumscribe a circle. The poles have axial end portions inwardly extending towards a centerline of the circle. The pneumatic tube extends about the set of poles proximate the base. The cap secures the axial end portions of the poles about the centerline, wherein the cap comprises radially extending grooves receiving the axial end portions of the poles.
