The effects of concentric training at two angular velocities on trained and untrained strength gains

This study aimed to determine whether the non- dominant unilateral concentric isokinetic knee extensors and flexors strength training at 60°/s and 180°/s results in speed specific strength gains in trained and untrained limb. Twenty three female kinesiology students (age: 21±2 years ; BH: 168±5 cm ; BW: 62±8 kg) were divided to slow training (STG) or fast training (FTG) group. Both groups performed a 4-week non-dominant unilateral concentric isokinetic knee extensors and flexors strength training at 60°/s and 180°/s, respectively. Statistically significant strength gains occurred in trained and untrained extremity at both angular velocities in STG, while FTG improved only trained extremity strength at both angular velocities. Repeated measures ANOVA showed there were no statistically significant differences between trained extremity effect sizes, while statistically significant differences occurred between the groups in lower velocities strength gains at untrained extremity. Unilateral concentric isokinetic training causes general and speed specific strength gains in trained and untrained extremity, respectively. Fast group showed speed specific strength gains in untrained limb.
