Dietary Intake over a 7-Day Training and Game Period in Female Varsity Rugby Union Players

This study estimated the daily energy intake (EI) and energy expenditure (TDEE) in female varsity rugby union players during a weekly training/game cycle. Fifteen (nine forwards, six backs) players (20.5 +/- 0.4 y, 167.1 +/- 1.8 cm, 74.9 +/- 2.9 kg) were monitored for a 7-day period (one fitness, two heavy training, one light training, one game, and two recovery days) during their regular season. The average EI throughout the week for all 15 players was 2158 +/- 87 kcal. There were no significant differences between days, but the lowest EI (1921 +/- 227 kcal) occurred on the mid-week recovery day and the highest on game day (2336 +/- 231 kcal). The average TDEE was 2286 +/- 168 kcal (similar to 6% > EI). The mean energy availability (EA) over the 7-day period was 31.1 +/- 3.6 kcal/kg FFM/day for the group. Of the players, 14% were in the optimal EA range (>45 kcal/kg FFM/day); 34% were in the moderate range (>= 30-45 kcal/kg FFM/day); and 52% had a poor EA of <30 kcal/kg FFM/day. Carbohydrate (3.38 +/- 0.36 g/kg/day, 45% of EI); fat (1.27 +/- 0.12 g/kg/day, 37% of EI); and protein (1.38 +/- 0.12 g/kg/day, 18% of EI) consumption remained similar throughout the week (p > 0.05). The players consumed 6% less energy than they expended, providing poor to moderate EA; therefore, daily carbohydrate intake recommendations were not met.
