Abstract
The purpose of the present study was to examine age-related changes in
isokinetic leg flexion and extension peak torque (PT), PT/body weight (PT/
BW), and F*T/fat-free weight (PT/FFW) in young wrestlers. Male wrestlers (A^
= 108; age M ± SD = 11.3 + 1.5 years) volunteered to be measured for peak
torque at 30, 180, and 300° • s'. In addition, underwater weighing was performed
to determine body composition characteristics. The sample was divided
into six age groups (8.1-8.9, n = 10; 9.0-9.9, n= 11; 10.0-10.9, n = 25;
11.0-11.9, n = 22; 12.0-12.9, n = 28; 13.0-13.9, n= 12), and repeated measures
ANOVAs with Tukey post hoc comparisons showed increases across
age for PT, PT/BW, and PT/FFW. The results of this study indicated that there
were age-related increases in peak torque that could not be accounted for by
changes in BW or FFW. It is possible that either an increase in muscle mass
per unit of FFW, neural maturation, or both, contributes to the increase in
strength across age in young male athletes.
