Energy availability and macronutrient intake over a 7-day training period in adolescent rugby players
Abstract
Background Understanding the dietary intake of elite adolescent athletes and its adequacy with sport nutrition recommendation is a key issue for health and player development, as well as performance and recovery. Energy availability needs to be considered to ensure optimal health and performance in young athletes. The present study aimed to quantify energy availability, energy expenditure and macronutrient intake in young male rugby union players competing at national level. Methods Twelve male adolescent players (15.6±0.6 years) completed a 7-days prospective observational study (5 days of training and 2 days of full recovery). Total energy expenditure was estimated using indirect calorimetry and heart rate measurement. Energy intake was assessed using weighed food by a dietitian in cafeteria (training days) and image-based dietary (recovery days). Energy availability was calculated using (energy intake-exercise energy expenditure)/fat-free mass. Results Mean energy availability was 38.5±7.5, 40.2±5.4 and 47.8±5.1 kcal/kgFFM/d on heavy training, moderate training and recovery days, respectively. Players consumed a low carbohydrate (~5.0 g/kg/d), high protein (~2.0 g/kg/d) and high fat (~1.8 g/kg/d) diet on training and recovery days in relation to current international nutritional recommendations for young athletes. Conclusions Athletes showed sub-optimal energy availability on training days, high energy availability on recovery days and did not comply with carbohydrate inta…

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
