Abstract

The success of performance in basketball may rely on both optimal body composition and nutrient intake. To our knowledge this is the first study to examine dietary intake adequacy and season-long effects on body composition and metabolism. The purpose of this study was to examine seasonal changes in body composition (BC), resting metabolic rate (RMR) and respiratory quotient (RQ), while also examining the dietary intake adequacy of NCAA DI male basketball players. BC, RMR and RQ were assessed during pre-season, in-season, and post-season (September, December, and March), while dietary assessment was collected in September and February. Results of this study indicated that players consumed inadequate amounts of energy (ppp< 0.0001) relative to the recommendations for exercising individuals during the October baseline period. However, following analysis and consultations, athletes increased intake and received adequate amounts of energy and protein during follow-up, yet carbohydrate (p=0.0025) was still significantly lower. Results also revealed that there was a decrease in percent body fat (%BF) during season, an increase in Lean Body Mass from preseason to postseason, a peak in RMR during season and an increase in RQ post season. These findings indicate that significant metabolic and body composition changes occur in players over the season and suggest nutritional strategies employed concomitantly may be beneficial.
