(9) The present invention is explained by specific example which visually shows ways of achievement by the given set of the required technical result features, which, however, is not unique.

EXAMPLE 1

(10) The handle of IPE is fixed by hand muscles, by gripping the handle of IPE with the palm, when the trainee starts to make sharp movements by a hand from side to side in front of himself/herself, IPE starts to cave in and accumulate kinetic energy and release the potential energy (due to bending, internal compression and stretching) and also creating resistance to counter air flows which leads to unique muscular performance.

(11) In a cases when IPE clamped in a hand, lies over a hand and rests in an idle mode before sharp advance move by the trainee is made, IPE due to its light weight and the ergonomics, instantly creates loading to muscles at the moment of eccentric retraction of muscles, and consequently influencing isometric and concentric traction of muscular fibers followed by immediate final phase of a punch when IPE gets overflowed by a hand, thereby (at the right time), transferring kinetic energy to the potential. At the return movement of a hand and IPE (to the body or to a stance) the release of the potential energy, the auxiliary accompanying movement of IPE occurs and additional auxiliary control of a hand movement, which trains the necessary specific technical skills.

(12) While exercising with the use of IPE in combination with other sport equipment when IPE is clamped in a hand, lies over a hand and rests in an idle mode before sharp advance movement by the trainee is made to move the object, IPE due to its light weight and the ergonomics, instantly creates loading to muscles, forcing a hand to make a more powerful jerking or impacting movement where kinetic energy is lost in the last phase of a movement. Thus, at the moment of IPE contact with a surface of a punch bag there is a loss of energy and clicking sound occurring as an integral part of an ergonomic features of this IPE, and the click is perceived by the user as the sound notification on the quality of the performance.

(13) Head mobility of IPE is carried out due to return-flexion function of the connecting element of a flexible polymer (e.g. rubber, plastic) where the IPE handle can take the part of the flexion-return function.

(14) IPE can be applied in order to gain plyometric effect (a shock method) during exercises of the upper body.

(15) 1) IPEs, due to their physical properties during the movements are capable of accumulating a number of forces which subsequently cause eccentric and concentric traction of muscles;

(16) 2) physical properties of IPE allow to regulate the moment of isometric traction of muscles, aiming this moment at the necessary group of muscles;

(17) 3) achieving plyometric effect in hands muscles, this effect automatically felt by the upper body and the legs creating effect of a spring for the whole body;

(18) 4) IPE has properties to stimulate additional energy after performance of a fast and vigorous direct stroke where in a final phase of a muscle punch and IPE itself releases potential energy which is used in return movement.

(19) 5) biological effect: titinthe main protein responsible for adaptation to plyometric exercises. The carried-out researches (Lindstedt S L, et al., 2002; Reich T E, et al., 2003) showed that the largest, but viscous isoforms of titin are discovered in elephants, and the smallest, but rigid are found in shrews. These results testify close link of the steps frequency and rigidity of titin. At the same time these results testify that titin is a muscular shock-absorber which possibly, is essential and potentially helps musculs and ligament elasticity. Structural properties of titin in many respects define muscular elasticity. As the source of an increased muscular rigidity, titin, probably, plays a key role in protective effect at the subsequent plyometric exercises (Reich T E, et al., 2000);

(20) 6) using IPE makes it possible to create a special type of load for underdeveloped and deep muscles. Also individual characteristics of all IPE allow to involve so-called fast fibers of muscles;

(21) 7) IPE clearly demonstrates its capacity to create a cross training effect, when the acquired skills of one hand (e.g. right hand) due to the neuro impulses exchange are transferred to the other (e.g. left) hand.

(22) 8) physical properties of IPE influence position of joints both at the start of the movements, during the movements and during a final phase of a punch;

(23) 9) IPEs fundamentally change the nature of body resources, gradually bringing the trainee to the possibility to develop technically difficult jerking movements and skills associated with professionals;

(24) 10) the sound effect provides and opportunity to control the quality of exercises. This sound notification of the punch against the bag is urged to notify about the quality of the exercise performance;

(25) 11) global careful researches proved thatunder the influence of shock movements, the athlete receives a great number of useful skills, in particular: muscles gain elasticity, hands joints improve mobility, wrists become stronger and strength of the wrist increases. The punch is combined with a sharp exhalation and consequently with tension of respiratory muscles, it helps to form and stabilize breath of the boxer, and also brings up ability to concentrate on efforts at the moment of the punch (USSR round training exercise. Chernyi V. G. head teacher of the boxing department of the state central institute of physical training, Master of Sports of USSR);

(26) 12) prevention of injuries and the illness known as The knuckle of the boxer due to the load redistribution from the top surface of the wrist to its bottom with the subsequent reduction of pressure on the wrists;

(27) 13) prevention of head concussion. It is well-known that at work-out of the athlete using the punch bag, even if the athlete uses traditional (special) gloves, at the time of strong punch the brain undergoes a mini concussion. IPEs are arranged in such a manner that even at striking of more powerful blows with stronger peak movements, the athlete does not injure the brain despite of creating the load for the whole body.

(28) 14) possibility of working out with the use of paws (workout with the trainer);

(29) 15) using IPEs in difficult attacking actions where muscles of legs, upper body and hands are involved, there is an equal distribution of loading and more rational splash of energy, in comparison with the similar use of any other means and equipment due to which the body power consumption decreases. For example, if the trainee uses different weighting compounds which fasten on wrists or clamped and held by the palm, during a final phase of a muscle movement the athlete is compelled to fight with kinetic energy of weighting compounds which leads not only to an overstrain and energy waste, but also is essentially and negatively influences the technique of a workout of the return technical moves.
