Biomechanical evaluation of the push-up exercise of the upper extremities from various starting points

The purpose of the present research was to evaluate the push-up exercise of the upper extremities in respect of biomechanics, to compare the muscle function, while changing the position of performance and to examine the torso's inclination during the exercise. The result is that the activation of the muscles, apart from the triceps brachii muscle, does not differentiate significantly in any of the positions. Moreover, the elevating the hands above the feet position is not recommended in protocols where the aim is to improve the muscle force because it displays the lowest mean value of vertical force and a low RFD. On the other hand, the standard push-up position is considered to be the most appropriate when the aim is to improve the triceps brachii muscle's force because it displays the highest RFD and the highest activation of this muscle. Finally, the correct body position during this exercise prevents from incorrect and damaging inclinations of the torso. © JPES
