Anthropometric characteristics and neuromuscular function in young judo athletes by sex, age and weight category
- 306 Downloads
The aim of the study was to examine anthropometric characteristics and neuromuscular function in young judo athletes by sex, age and weight category.
146 child and cadet judo athletes were examined for height, body mass (BM), body fat percentage (BF), countermovement jump (CMJ), sit-and-reach (SAR) test and handgrip muscle strength (HMS).
The results showed that male adolescents were taller, had more HMS, and less BF and flexibility than girls. Significant differences in the sex and weight category were observed, chiefly in BF and body mass index. There were no differences in time to peak force of HMS and CMJ.
Based on these findings, special attention should be put to heavy BM categories targeting low BF and high muscle mass, which might contribute to improved neuromuscular function and in turn contribute to the dynamics randori. This study might help profiling the young judoka taking into account sex, age and BM category.
