Effects of seven days’ fasting on physical performance and metabolic adaptation during exercise in humans

Effects of seven days’ fasting on physical performance and metabolic adaptation during exercise in humans

Humans have, throughout history, faced periods of starvation necessitating increased physical effort to gather food. To explore adaptations in muscle function, 13 participants (7 males and 6 females) fasted for seven days. They lost 4.6 ± 0.3 kg lean and 1.4 ± 0.1 kg fat mass. Maximal isometric and isokinetic strength remained unchanged, while peak oxygen uptake decreased by 13%. Muscle glycogen was halved, while expression of electron transport…

BCAA may enhance metabolism and reduce post-exercise fatigue: Study

A recent study published in Nutrients shows that BCAA supplementation enhances fat oxidation, improves exercise efficiency, and reduces post-exercise fatigue in young active males. The research highlights BCAAs' potential to support metabolism, preserve glycogen levels, and mitigate central fatigue during high-intensity exercise.
