Abstract

INTRODUCTION: General recommendations for the daily intake of macronutrients in elite sports exist and vary depending on training
intensity and training volume. Recently we have shown that carbohydrate (CHO) intake in young female football players is at the lower
range of the recommendations (Braun et al., 2018). However, not just absolute and relative intakes should be considered, but also the
timing of carbohydrate and protein intake before, during and after training. Therefore, the purpose of this evaluation is the examination of
CHO and protein intake around training sessions among young female football players playing in the highest age-related division.
METHODS: Dietary data of 22 training sessions undertaken by 10 young elite female football players (15.6 ± 0.5 yrs, 105.9 ± 22.1 min daily
training volume) were evaluated, using a 3-day weighed record, complemented by a diet history interview. Based on the German food
database (BLS 3.01) using OptiDiet Basic Software, the intake of CHO within 4 hours prior to exercise and during exercise as well as CHO
and protein intake within 1 hour after exercise was analyzed and compared to current recommendations for pre- and post-exercise
nutrient recommendations for optimal sports performance (Thomas et al., 2016).
RESULTS: CHO intake was on average 0.84±0.54 g/kg bodyweight (BW) in the 4 h prior to exercise. Within the first hour after exercise CHO
intake was 0.29±0.48 g/kg BW and absolute protein intake 6.57±8.03 g or 0.11±0.13 g/kg BW, respectively. There was no CHO intake
during exercise.
CONCLUSION: Based on well accepted recommendations (Thomas et al., 2018) a sufficient CHO intake was not met prior, during and
after exercise. Only one player had a sufficient CHO intake prior to a single training session. After exercise, the recommendation of combined
absolute protein intake of 15-25 g or relative protein intake of 0.25-0.3 g/kg BW and CHO intake of 1-1.5 g/kg BW (Thomas et al.,
2016) was only met once. These data show that there is a high potential to enhance timing of CHO and protein intake around training
sessions and underline the importance of nutritional education in young athletes, maybe especially in team sports.
