Cycling-specific isometric resistance training improves peak power output in elite sprint cyclists

Abstract

Introduction: This study aimed to assess the efficacy of a 6-week cycling-specific, isometric resistance training program on peak power output (PPO) in elite cyclists. Methods: Twenty-four elite track sprint cyclists were allocated to EXP (n = 13, PPO, 1537 ± 307 W) and CON (n = 11, PPO, 1541 ± 389 W) groups. All participants completed a 6-week training program; training content was identical except participants in the EXP group replaced their usual compound lower body resistance training exercise with a cycling-specific, isometric resistance training stimulus. Cycling PPO, knee extensor and cycling-specific isometric strength, and measures of muscle architecture were assessed pre- and post-training. Results: In EXP, absolute and relative PPO increased (46 ± 62 W and 0.8 ± 0.7 W/kg, P
