Correlation between time to peak torque and peak torque to vertical jump in college-age athletes.

摘要

The vertical jump is an essential part of athletics to gain an advantage over the opponent. Isokinetic testing provides quantitative data to determine power and how fast power or peak torque is achieved.; In this study, after 20 NCAA Div. II athletes were measured for three trials of maximal vertical jump, they completed an isokinetic test of knee extension at speeds of 60, 180, and 300°/sec.; The results showed a significant correlation (p 0.05) between peak torque at a speed of 300°/sec and vertical jump p = 0.019.; As a result of this study it was found that the vertical jump test is a test of muscle power generated by the quadriceps muscle group, and relates to peak torque values documented by isokinetic testing at 300°/sec of knee extension.
