Muscle pain from an intramuscular injection of hypertonic saline increases variability in knee extensor torque reproduction

NEW & NOTEWORTHY: We provide novel data demonstrating that the presence of muscle pain interferes with estimations torque produced by knee extensors, which could impair judgment work rate during endurance exercise. The novelty our study is in application hypertonic saline experimental model into a quadriceps short, submaximal isometric contractions at an intensity provides more translatable assessment impact exercise-induced on work-rate regulation whole body
