Influence of resistance training on muscle hypertrophy in young athletes

Abstract

Resistance training is widely recognised as an effective stimulus for promoting skeletal muscle hypertrophy, yet its influence on young athletes remains a subject of ongoing scientific inquiry due to developmental and maturational considerations. This study examines the impact of structured resistance training programmes on muscle hypertrophy among young athletes, focusing on training variables such as intensity, volume, frequency, and progression. Drawing on empirical evidence, the research evaluates physiological adaptations including increases in muscle cross-sectional area, neuromuscular efficiency, and protein synthesis rates during adolescence. Particular attention is given to the interaction between growth-related hormonal changes and mechanical loading, which collectively modulate hypertrophic outcomes. The review also considers safety, supervision, and technique as critical moderating factors influencing training effectiveness in youth populations. Overall, the findings indicate that appropriately designed and periodised resistance training can significantly enhance muscle hypertrophy in young athletes, thereby improving strength, performance capacity, and long-term athletic development while minimising injury risk.
