Title Alternative
Body composition, cardiorespiratory fitness, and running performance in junior male long distance runners

Abstract
The purpose of this investigation is to quantify body composition and cardiorespiratory fitness in 46 junior male long distance runners and to evaluate the effects of these factors on running performance. Total and regional body composition were measured using dual energy X-ray absorptiometry. Maximal oxygen uptake (VO(2)max), ventilatory compensation point (VCP), and ventilatory threshold (VT) were determined during the maximal exercise test using a bicycle ergometer. Subjects were classified into two groups. The 5000m running times of 18 subjects in group I were less than 15 min, and those of 28 subjects in group II were more than 15 min. %Fat of the legs in group I was significantly decreased compared to that of group II. VCP and VT of group I were significantly higher than those of group II, while VO2max was not significantly different between the two groups. VO2max, VCP, and VT were negatively correlated to running times, while the parameters of body composition were not correlated. The increase in VCP alone contributed to running time shown by multiple regression analysis. These data showed that VCP is a sensitive predictor of running performance in junior male long distance runners during development.
