Abstract

Purpose: To quantify total daily energy expenditure (TEE) of international adult female soccer players.

Methods: Twenty-four professional players were studied during a twelve-day period where they participated in an international training camp (also inclusive of two competitive games) representing the English national team. TEE was assessed via the doubly labelled water (DLW) method during the full 12 days as well as the initial 4-day period prior to game one. Energy intake (EI) was also assessed (via weighed food analysis) during the initial 4-day period to permit estimation of energy availability (EA).

Results: Mean TEE did not differ (P = 0.31) between the 12-day (2693 ± 432 kcal.day-1; range: 2105-3507; 54 ± 6 kcal.kg-1 fat free mass, FFM) versus the 4-day assessment period (2753 ± 359 kcal.day-1; range: 1942-3280; 56 ± 8 kcal.kg-1 FFM). Mean four-day EI was 1923 ± 357 kcal.day-1 (range: 1639-2172) and mean activity energy expenditure was 1069 ± 278 kcal.day-1 (range: 155-1549 kcal.day-1). When assessed for estimated EA, 88% of players were categorised with low EA status according to the threshold of <30 kcal.kg-1 FFM. Mean daily carbohydrate intake equated to 3.3 ± 0.7 g.kg-1 body mass.

Conclusion: When compared with previously published data from adult male players, we demonstrate that the relative daily energetic requirements of engaging in professional soccer training and match play is comparable between sexes. From a practical perspective, data suggest that practitioners should likely focus education and behaviour change strategies on “fuelling” for match play and training to optimise both player health and performance.
