Resistance exercise increases postexercise oxygen consumption in nonexercising muscle.
This study examined the effect of knee extension resistance exercise on muscle oxygen consumption in nonexercising forearm flexor muscles (nonexV(O)(2mus)) after exercise. Seven healthy male subjects were performed six sets of unilateral knee extension exercise until exhaustion at 40, 60, and 80% of 1 repetition maximum (RM) on separate days. ⋯ NonexV(O)(2mus) returned to the resting values after 1-5 min of recovery and then showed no further significant change for all exercise intensities. This study suggests that knee extension resistance exercise at 40, 60 and 80% 1RM induced an increase in nonexV(O)(2mus) and that the increase of nonexV(O)(2mus) after exercise returned to resting value in several minutes.
