This dataset contains data of a study that investigated whether fish protein, vitamin D, and ω3 supplementation enhanced adaptations to high-intensity functional training (HIFT). Specifically, it includes participant characteristics along with anthropometric, supplementation, training, and performance measurements.

This dataset contains data of a study aimed at investigating the effects of egg white and whey protein supplementation during HIFT on physical performance in trained individuals. Specifically, it contains the characteristics of the participants, anthropometric, supplementation, training, and performance data.

This study examined the effect of pre-exercise carbohydrate intake on blood glucose, blood lactate, and performance in competitive swimmers during sprint interval swimming. Ten male and 11 female swimmers performed two 4 × 50-m maximal sprint trials in their specialized stroke, spaced two days apart, in a random, counterbalanced order. In one trial (carbohydrate trial), the participants consumed a candy providing 1 g carbohydrates per kg body weight one hour before exercise, while, in the other trial (no-carbohydrate trial), they did not eat the candy. Blood glucose and lactate were measured before, immediately after, and 30 min after exercise. Performance time for each 50 m was recorded.
