Are professional young rugby league players eating enough? Energy intake, expenditure and balance during a pre-season.

摘要: Due to the unique energetic demands of professional young collision sport athletes, accurate assessment energy balance is required. Consequently, this first study simultaneously investigate intake, expenditure and rugby league players across a pre-season period. The total six male was measured via doubly labelled water over fourteen-day Resting metabolic rate physical activity level calculated. Dietary intake reported Snap-N-Send non-consecutive ten-day period, alongside changes in fasted body mass hydration status. Accordingly, inferred. mean (standard deviation) difference between (16.73 (1.32) MJ.day−1) (18.36 (3.05) period unclear (−1.63 (1.73) MJ.day−1; ES = 0.91 ± 1.28; p = 0.221). This corresponded most likely trivial decrease (−0.65 (0.78) kg; ES = 0.04 ± 0.03; p = 0.097). 11.20 (2.16) MJ.day−1 1.7 (0.2), respectively. For time, utilises gold standard techniques elucidate distinctly large expenditures emphasising requirement for equally intakes achieve targeted composition adaptations. it imperative that practitioners regularly assess collision-sport athletes ensure their requirements are achieved.
