Eating Habit, Nutritional Status and Physical Activities in Female High School Tennis Players

摘要

In this study, we investigated the eating habit, the nutritional status and the physical activities during the periods of the summer training in female high school tennis players and consider a remedy to improve the condition of them. Twenty-five female high school tennis players responded to questionnaires about the life style and eating habit, and recorded the contents and amount of their diet for 3 days in detail. Moreover, we chose 5 subjects at random from regular and nonregular players respectively, and measured their total energy expenditure on a designated day. In the 3-days diet record, approximately 50 ％ of subjects ate only grain dishes several times of 3-day meals. It was all for lunch. In addition, the way of snack selection and the timing of taking it were not appropriate. Moreover, the average of the energy expenditure of regular and non-regular players were 2511±192kcal and 2264 ±141 kcal, respectively, and there is no significant difference between both groups. The quantity and the nutritional balance of meals are almost same in both groups. However, the physical activities more than 4 Mets in regular players group (684±95 kcal) is significantly higher than that of the non-regular players group (459±104 kcal). We suggested that it is necessary for the players to be instructed how to take nutrition according to their own physical activities, especially for lunch and snacks, to improve their performance and physical conditions.
