Physical exercise (PE) significantly influences insulin sensitivity (IS), glucose control and overall metabolic health. While PE effectively enhances IS and glucose regulation, the timing of nutrient intake, before and after exercise, plays a crucial role in modulating its effects. The aim of this study is to evaluate how pre- or post-evening exercise carbohydrate (CHO) ingestion influences glucose metabolism and substrate oxidation (fat/CHO) during exercise and after exercise in athletes during the nocturnal period and the morning after during an oral glucose tolerance test (OGTT).

To investigate change in glucose tolerance during a 75g glucose, 120 min oral glucose tolerance test (OGTT)
Timeframe: Comparing the change in glucose tolerance during the OGTT between baseline (no exercise) week 0, compared to interventions week 1 and week 2 involving previous evening exercise, with carbohydrates consumed either before or after exercise.
