Research Abstract

At first, we investigated the desire and its reasons for weight loss, the prevalence od disordered eating patterns (DEP) and menstrual status, by using written questionaires and Eating Attitude Test-26 (EAT-26), in Japanese female athletes (n= 1000) and nonathletic controls (n=593). In the categories of endurance I (athletes competing in sports where leanness is considered important) and aesthetic groups, the prevalence of DEP and amenorrhea were significantly higher than in the nonathletic controls. These data indicate a significantly higher prevalence of DEP and menstrual dysfunction in the athletes involved in sports where leanness is emphasized, and a close relationship among undernutrition, low body weight and menstrual dysfunction.
In contrast, in Chinese female athletes, the prevalence of DEP is low (technical 1.5%, endurance I 3.3%, endurance II (athletes competing in sports where leanness is considered less important) 1.6%, aesthetic 3.0%, ball-game 3.0% and power sports 0.9%), and did not differ from that in nonathletic controls (0.7%). The prevalence rates of amenorrhea was also low both in athletes and nonathletes. It was suggested that a low prevalence of DEP in Chinese athletes stems from low socioculturally- and socioeconomically-imposed desires to be thin and low requirements for weight loss to improve athletic performance.
Thirdly, we investigated the effects of endurance exercise and food restriction (70%) on the resting metabolic rate and bone metabolism in young female rats. Voluntary running exercise concurrent with food restriction increased serum lipid levels and estradiol concentration. Resting O_2 uptake was not different among both exercise and non-exercise groups and control and restricted groups : Unfortunately, we could not examined bone mineral.
