College females performed maximal two-legged isokinetic knee extensions and flexions 15~25reps, 5~6 sets in single sessions third a week for 6weeks at either 60deg/sec(Slow) or 240deg/sec(high) or both 60 and 240deg/sec (combined using a Cybex
II+
isokinetic dynamometer with potentiality of knee injury.
@ES The results were as follows;
@EN 1. Isokinetic strength training effect of knee extension and flexion muscle torque with specific angular velocity.
1) The peak torque at 60deg/sec significantly increased(p<0.05) in low speed group.
2) The peak torque at 180deg/sec significantly increased(p<0.05) in combined speed group.
3) The peak torque at 240deg/sec significantly increased(p<0.05) in combined speed group.
2. Isokinetic strength training effect of reciprocal ratio(H/Q ratio) with specific angular velocity .
1) Reciprocal ratio of left knee did not differ between pre and post.
2) Reciprocal ratio of right knee significantly increased(p<0.05) in low speed group but did not differ significantly in comnbined speed group.
3. Isokinetic strength training effect of bilateral difference(R/L difference) with specific angular velocity.
1) bilateral difference of quadriceps significantly improved (p<0.05) in high speed group and combined speed group in all the velocity.
2) Bilateral difference of hamstrings at 60deg/sec significantly improved(p<0.05) in low speed group and combined speed group and indicating the greater relative increase in combined speed group compared to other group.
Examined the strength training effecct inducing all the component, muscle poser, reciprocal ratio, ad bilateral difference, the combined training, mixed by low, mid, and high speed and concerned velocity specification in isokinetic strength
training is
more effective in improvement of bilateral difference and incremet of peak torque at 180deg/sec and 240deg/sec.
