Human development was permanently conditioned and obtained through physical motion. The physical state together with the cardiorespiratory fitness state highlight the development of the physical capacity of the human being. The explosive force (expansion/dГ©tente) is a basic parameter, which lays emphasis on the physical fitness level. This study aims to make a comparative analysis of the explosive force measurement on the inferior limbs using as measurement instrument two modern devices: the Myotest Pro and OptoJ...

Mechanical systems for producing mechanical vibrations gained more and more the role of training equipment and the vibrations obtained have an effect on muscles, facilitating the contraction or relaxation reflex depending on the possibilities of adjusting their parameters. Vibration platform training generates a tonic stretch reflex in all the muscles involved in the effort. During this reflex, the muscles contract and relax at very high speeds and the amount of active fibers reach 95% of muscle fibers involved in...
