Does exercise-induced muscle injury alter hemodynamic responses during exercise?
p-value: p=<0.03
Exercise-induced muscle injury augments forearm vascular resistance during isometric knee extension, suggesting altered vascular control to non-exercising skeletal muscle.
Ray et al. (1998) studied this question. Exercise-induced muscle injury vs. Preinjury state and contralateral control leg was evaluated on Forearm vascular resistance during the second and third minutes of exercise (p=<0.03). Exercise-induced muscle injury significantly increased forearm vascular resistance during the second and third minutes of isometric knee extension exercise (P<0.03).
