Big vs powerful : molecular signalling responses to hypertrophic and power resistance exercise modalities

2015

Introduction: The effects of resistance exercise (RE) loading on molecular signalling proteins, including those involved in protein translation and thus skeletal muscle hypertrophy have been extensively studied. However, there is little research on high power RE loading and molecular signalling proteins, and also on possible relationships between signalling proteins and recovery from RE loading. Methods: 7 young men (31±6 years, 178.9±4cms, 84.6±5 kgs) performed 1 hypertrophy loading session (HYP) (5x10 80% 1RM leg presses (LP)) and 1 power loading session (POW) (10x5 70% 1RM LP), with each session separated by 7 days, in a crossover design, prior and subsequent to 12 weeks of resistance tr…
