ISOMETRIC RESISTANCE TRAINING EFFECTS ON LOWER LIMB MUSCLE ACTIVITY
ABSTRACT Introduction The high muscular strength in the hip joint is the foundation of jumping ability. Isometric resistance training includes the process of takeoff and landing, recruiting a more extensive set of muscle groups. Objective Analyze the isometric resistance training effects on lower limb muscle activity, including the coactivation of the antagonist’s muscles. Methods By mathematical statistics, weight-bearing isometric resistance training effects on lower extremity maximal muscle strength and explosive power were observed. Changes in coactivation and preactivation levels of lower extremity antagonist muscles data are evaluated and compared before and after isometric resistance training. Results The peak angular velocity of the joints at the hip and ankle in the isometric resistance training group is significantly higher than the control group. There was no significant difference in the peak angular velocity of the knee between the groups (P<0.05). Conclusion Isometric resistance training can shorten the return period, shorten the amortization period, and increase the energy conversion capacity in the muscle-tendon complex. Evidence level II; Therapeutic Studies - Investigating the results.
