Presentation Abstract

BACKGROUND: Energy availability (EA) is the amount of energy available for normal physiological processes and is defined as energy intake (kcals) minus exercise energy expenditure (kcals) relative to fat free mass (FFM). Low-energy availability (LEA; i.e., energy intake < 30 kcal/kg FFM/d) causes Relative Energy Deficiency in Sport, which results in various negative health and performance outcomes. A recent study reported 81% of the female collegiate athletes examined exhibited LEA. Of the 18-collegiate beach volleyball (BVB) athletes studied, average EA across 7 days was determined to be 12.44 kcal/kg FFM/d. Notably, this is a 7-day snapshot that may not reflect chronic dietary or training patterns. To our knowledge, no study has examined EA across the 10-week competitive season in this population. Therefore, the purpose of this cross-sectional study is to establish the risk of LEA in female collegiate BVB athletes across the competitive season. METHODS: We plan to recruit 18 female collegiate BVB athletes. Each subject will complete an initial visit where anthropometrics, resting metabolic rate (RMR), nutrition knowledge, psychological skills and maximal aerobic capacity will be tested. During weeks 1, 5, and 9 of the competitive season, in addition to initial testing, energy intake (ASA 24) and energy expenditure (GT9X-Link) will be assessed to calculate EA. Countermovement vertical jump height, velocity, and power (GymAware) will be used to assess performance. Results will be analyzed using repeated measures ANOVA and Pearson Correlations. EXPECTED RESULTS: It is hypothesized that LEA will be present and EA will decline as the season progresses.
