Vertical Jump Characteristics and Lower Limbs Muscular Contribution in Chilean Volleyball Players during the Counter Movement Jump (cmj)
نویسندگان
چکیده
The purpose of this study was to determine and to compare characteristics of the lower limb extension musculature in Chilean indoor and beach volleyball players and the muscular contribution during the CMJ. The sample was composed by 13 subjects belonging to the Chilean elite beach and indoor volleyball. The subjects performed 3 CMJ jumps for average determination of the height of the jump, eccentric force development rate (TDFE), concentric force development rate (TDFC), power and lower limbs muscular contribution, evaluated using force platform and wireless electromyography (EMG). The results demonstrated a significant relationship between the height of the jump-TDFC and power-TDFC and Medial vasti muscle has obtained the most significant contribution during the CMJ in volleyball players.
