Most sports that involve the use of upper body strength transfer that force along the posterior kinematic chain that begins at the point of contact of the feet and the ground. Whenever an athlete presses against an opponent, throws an object, hits a ball with a racket or stick, or transfers force to any object, that force begins when the feet add pressure to the ground. In the case of the extrusion on the head, the return band, namely all the elements of the musculoskeletal system that generate and transfer force between the base of the support and the sale of the moving load, start with the floor and end with folded hands on the bar.

For an exercise to be beneficial for your sport, it must force the same muscles to work and use the same type of neurological activation pattern that occurs when playing that particular sport. It should be noted, however, that this is not a copy of the characteristic height movements. It has even been shown that the excessive similarity of the motor trajectory of an exercise performed more slowly (due to an additional load) than that activated during faster and already developed movements, can interfere with the effectiveness of the exercise.

their later use (an example can be thrown at a basket with a heavier ball or throwing a volleyball attack with additional rubber resistance). As a result, it may turn out that our throws or attacks will be made at a slower rate, and thus we will lose precision and speed of movement. In addition, heavier balls or rubbers can interfere with our technique, which is so important in sport. It has long been known that it is easier and more accurate to throw a ball of the appropriate size and weight (eg a basketball) at a target than a huge medicine ball (weighing 50 kg).
