The research scope of surface EMG technologies applied to the lower limbs is broad and extensive, encompassing a wide range of activities such as cycling, sprinting, diving, Tai Chi, and parachuting. The comprehensive array of experimental methodologies employed in previous studies, as well as the resulting data, have provided valuable reference and insight for the composition of this paper. Specifically, in the investigation of the take-off technique for blocking in volleyball, the use of full-range surface EMG testing on athletes' lower limbs allows for the analysis and comparison of activation sequences, mobilization ratios, and levels of engagement, as well as the interrelationships between muscles such as quadriceps femoris, sartorius, biceps femoris muscle, semitendinosus, semimembranosus, medial thigh muscle and gastrocnemius muscle, at varying knee joint angles during the take-off. Such analysis elucidates the muscular characteristics at work during the blocking and take-off movement, offering physiological guidance for technical refinement and force training of athletes. These findings provide technical support for the further development of volleyball in our country and serve as a reference for research in other specialized fields.
