This study aimed at comparing the effects of strength and power training regimens on neuromuscular adaptations and changes on vertical jump performance, kinetics and kinematics parameters. Forty physically active males (178.2±7.0 cm; 75.1±8.6 kg; 23.6±3.5 years) with at least two years of strength training experience were assigned to a strength training (ST; n=14), a power training (PT; n=14), or a control group (C; n=12). The training programs were performed during eight weeks, three times per week. Dynamic and isometric maximum strength, cross-sectional area and muscle activation were assessed before and after the experimental period. Squat jump (SJ) and counter movement jump (CMJ) performance, kinetics and kinematics parameters were also assessed. Dynamic maximum strength increased similarly (p<0.05) for the ST (22.8%) and PT (16.6%) groups. MVIC increased for ST and PT groups (p<0.05) in the post-training assessments. There was a main time effect for muscle fiber crosssectional area (p<0.05) but there were no changes in muscle activation. SJ height increased, after ST and PT, due to a faster concentric phase and higher RFD (p<0.05). CMJ height increased only after PT (p<0.05) but there were no significant changes in its kinetics and kinematics parameters. In conclusion, neuromuscular adaptations were similar between the training groups. PT seemed more effective than ST in increasing jumping performance, but neither the ST nor the PT was able to affect the SJ and the CMJ movement pattern (e.g., timing and sequencing of joint extension initiation). |
