Sponsor's own description

This study investigates the effects of deloading periods (short breaks or reductions in training volume) in a 8-week resistance training program on muscle strength and hypertrophy in young, untrained individuals. Participants were randomly assigned to two training conditions: Deload Training Group: Reduced training volume for one week every four weeks. Continuous Training Group: Regular training without reductions. Muscle thickness was measured using ultrasound, and muscle strength was evaluated through a 10-repetition maximum (10RM) test before and after the intervention. The findings showed that both training strategies led to significant increases in muscle strength and size, with no major differences between groups. This suggests that incorporating deloading periods does not negatively impact muscle development and may serve as an effective alternative for individuals with time constraints or minor injuries. This study was conducted at Gaziantep University, Faculty of Sports Sciences, with approval from the university's ethics committee.
