Bone mineral density in male weight-classified athletes is higher than that in male endurance-athletes and non-athletes
Background
Weight-bearing physical activity and intense mechanical stimuli affect the bone through the endocrine system; hence, bone-loading sports affect bone mineral density. We hypothesized that weight-classified athletes, such as those practicing wrestling and judo, have relatively high bone mineral density because these activities have a higher impact on the entire body during daily training compared to low- or non-impact activities. We aimed to investigate the bone mineral density of weight-classified athletes (participating in wrestling and judo) to compare the parameters with those of endurance-athletes and non-athletes.
Methods
Thirty-three college athletes (aged 18-22 years) were divided into three groups, wrestlers, judoka, and endurance-athletes, according to their sports history. Eight non-athletes participated as controls. Bone mineral density was determined by whole-body dual-energy X-ray absorptiometry.
Results
Mean whole-body bone mineral density of wrestlers and judoka was higher than that of endurance-athletes and non-athletes (P < 0.01). The bone mineral density of athletes competing in wrestling and judo was higher than that of non-athletes when adjusted for body mass.
Conclusions
The present study demonstrated that weight-classified athletes have significantly higher bone mineral density compared to endurance- and non-athletes, despite rapid weight loss before competitions.
