Differences of energy intake and energy expenditure of elite Taekwondo players receiving summer vs. winter intensive training

[PURPOSE]: This study aimed to evaluate the energy expenditure and energy intake as an experiment of energy balance of elite Taekwondo players receiving summer vs. winter intensive training. [METHODS]: The summer training group (STG, n = 15) and the winter training group (WTG, n = 18) wore an accele...

description [PURPOSE]: This study aimed to evaluate the energy expenditure and energy intake as an experiment of energy balance of elite Taekwondo players receiving summer vs. winter intensive training. [METHODS]: The summer training group (STG, n = 15) and the winter training group (WTG, n = 18) wore an accelerometer for the measurement of energy expenditure and maintained a daily dietary record for measurement of energy intake, for seven consecutive days during summer or winter intensive training. [RESULTS]: The total energy expenditure (TEE) (834.1 kcal, p < .001), the total counts (1,867 counts, p = .038), and the energy expenditure during moderate (384.6 kcal, p < .001) and vigorous activity (351.8 kcal, p < .001) were significantly lower in the STG than in the WTG. On the other hand, the macronutrient intake showed that intake of energy (902.7 kcal, p < .001), carbohydrates (82.6g, p < .001), and protein (93.9g, p < .001) in the STG were significantly lower than those of the WTG. When comparing TEE and total energy intake, the STG consumed 902.7 kcal less as energy than the WTG, while the STG performed 834.1 kcal more as TEE than that of the WTG. [CONCLUSION]: In conclusion, both of the summer and winter intensive training are not proper for energy balance condition. Therefore, to promote the optimal energy balance during the summer or winter intensive training period, a training and sports nutrition program based on the amount of energy expenditure and energy intake for Taekwondo players should be considered.
