Article: Exercise-induced blood flow in relation to muscle relaxation period.(Research)

Authors: Fumiko Ohmori (corresponding author) [1]; Shizuyo Shimizu [2]; Atsuko Kagaya [3]

Background

The blood flow to an active muscle changes depending on the exercise intensity, contraction frequency, contraction-to-relaxation duty cycle, etc [1, 2, 3, 4, 5, 6, 7, 8, 9]. The blood flow increases markedly during the relaxation phase of dynamic exercise, whereas it remains at a lower level during the contraction period [10, 11, 12, 13, 14]. Thus, the magnitude of the blood flow during the relaxation phase of the dynamic exercise determines the magnitude of blood supply to the exercising muscles. Further, the manner in which an exercise protocols ...
