On the health control of female gymnasts during training camp - Body weight control and nutrition management / 体力科学

ABSTRACT

Body condition and nutritional intake of female competitive gymnasts (four athletes who participated in Universiade championships and seven athletes who passed preliminary trials for World championships) were investigated during intensive training camp, where they improved their technical skill of gymnastics and regulated their body weight through body training and dietary intake.<BR>The results are summarized as follows;<BR>1) Daily energy intake, protein intake (per 1 kg of body weight) and iron intake during training camp of Universiade and World athletes were 1, 566±292 kcal (mean±standard deviation), 1.29±0.08 g/kg, 6.6±1.6 mg, 1, 367±267 kcal, 1.24±0.19 g/kg, 6.6±1.4 mg respectively on the average. Each intake of them was low during training camp.<BR>2) The lower their daily energy intake, the more their body weight decreased. High correlation between energy insufficient (needed energy minus intaked energy) per 1 kg of body weight and body weight losses was observed. And also, high correlation between decrease of body weight and proportion of energy intake per basal metabolism was observed.<BR>3) Changes in body composition during the first training camp were detected; decrease of their body weight, body fats and lean body masses. Compared with the second training camp, the amount of body fats decreased, while the amount of lean body masses increased.
