%X Sa£¿etak This study examined energy expenditure, dietary behavior, and energy balance of female tennis and soccer student-athletes during a competitive season. A sample of 18 (Mage=19.86¡À1.35 years) Division I female collegiate student-athletes (5 tennis and 13 soccer players) were followed for four days, i. e., during one game/match, two practice sessions, and one recovery day. Physical activity was assessed with accelerometers and dietary behavior with daily food logs. Daily energy expenditure for the game/match, practice, and rest days was 2,848¡À304kcal, 2,622¡À248kcal, and 1,833¡À959kcal, respectively, with a statistically significant main effect (F[2,16]=82.291, p<.001, ¦Ç2=.91). Daily dietary intake ranged from 1,833¡À959 to 1849¡À371kcal, with no significant interaction between different days. There were no sport specific differences in energy expenditure or dietary behaviors. Athletes consumed 4.30¡À2.07 g/kg carbohydrates, 1.57¡À.98 g/kg protein, and 1.27¡À.80 g/kg fats daily. There was a significant main effect in dietary intake (F[2,16]=7.311, p=.006, ¦Ç2=.48), with a difference between game/match and recovery days (t[17]=3.83, p=.001, d=1.19). This study showed a negative energy balance among female student-athletes. The findings indicate that the lack of carbohydrate intake during game/match days contributed to this energy deficit

Female participation in intercollegiate sports has steadily increased after the enactment of the Title IX in 1972. It is reported that there are more than 200
%K 000 female intercollegiate athletes
%K with an average of 8.83 teams per National Collegiate Athletic Association school (NCAA
%K 2016). Tennis and soccer are among the top female sports at the collegiate level
%K with 90%/80% of universities having female soccer and tennis teams

%K 2016).
Adequate energy balance
%K i.e.
%K the balance between energy intake and total energy expend- iture (EE) (Hall
