| Abstract: | Purpose] This study investigated the effect of different gait speeds on the muscle
activities of the latissimus dorsi and gluteus maximus muscles in relation to the
posterior oblique sling system. Subjects] We recruited 14 young adult males. Methods] We
measured the left latissimus dorsi muscle activity and right gluteus maximus muscle
activity of all subjects while they walked on a treadmill at speeds of 1.5 km/h, 3.5 km/h
and 5.5 km/h. Results] There was a significant increase in latissimus dorsi muscle
activity with a treadmill speed of 5.5 km/h compared with 1.5 km/h and 3.5 km/h. The
gluteus maximus muscle activity significantly increased in the order of 1.5 km/h <
3.5 km/h < 5.5 km/h. Conclusion] The present results indicate that arm swing connected
to increasing gait speed influences the muscle activity of the lower limbs through the
posterior oblique sling system.Key words: Electromyography, Gait speed, Posterior oblique sling system |
