This 2024 examine, revealed within the Frontiers in Vitamin journal, examined how coaching throughout Ramadan’s fasting window in comparison with the consuming window impacted key metrics comparable to muscle mass, power, and hormone levels.
Each teams maintained the identical consumption of calories, water, and macros (protein, carbs, and fat), making certain a managed comparability. Contributors adopted an similar resistance coaching program. (1)
Outcomes
The examine discovered no vital variations between teams in physique fat loss or lean mass development. Nevertheless, the fed group confirmed notable enhancements in 1RM for squats and deadlifts. Each teams skilled comparable outcomes with the bench press.
The fed group noticed increased testosterone levels, whereas the fasted group exhibited higher cortisol levels.
