Previous studies have shown that cycling can directly influence neuromuscular control during subsequent running in some highly trained triathletes. A relationship between this altered of and musculoskeletal pain injury has been proposed; however, link not investigated. Purpose: This study aimed to evaluate the on triathletes with without exercise-related leg (ERLP). Methods: Participants were 34 triathletes: 10 a history ERLP 24 training-matched no ERLP. Knee ankle kinematics muscle recruitment compared baseline run (no prior exercise) transition (preceded by cycling; i.e., vs cycle run). Results: joint different runs for any absolute mean difference (±95% confidence interval) was 1.49° ± 0.17°. However, runs, defined EMG amplitude ≥10%, 5 (11/130 muscles exhibited recruitment) (12/50 recruitment). represents relative risk 2.40 (0.89-6.50; P = 0.089) when athletes 2.62 (1.34-6.01; < 0.01) muscles. The magnitude change (14.10% 2.34%) (16.31% 3.64%; 0.41). Conclusions: demonstrates an association their off bike.
