Tóm tắt

 BACKGROUND: The purpose of this study was to examine the relationships between the characteristics of force development and electromyographic activity of the quadriceps muscles in the isometric mid-shin pull (MSP) and the countermovement jump (CMJ) performed under different conditions. METHODS: Fifteen resistance-trained individuals (age = 25.9 ± 4.0 y
  body mass = 73.2 ± 11.7 Kg
  stature = 172.3 ± 9.5 cm) were tested for MSP and for the following CMJs: regular CMJ (CMJ)
  elastic band-assisted CMJ (CMJ RESULTS: Higher PF was registered in MSP compared to the CMJs ( CONCLUSIONS: Results of the present study showed that CMJs promote PRFD and the excitation of the vastus lateralis, to a greater extent compared to MSP. Regular CMJ performed at body mass may represent the best option for power development, and small variations in loads allowed by weighted vests or elastic bands do not seem to alter the characteristics of force development.
