[Purpose]

This study compared the muscle activities of sit-up and leg-raise.

[Subjects and Methods]

The subjects of this study were healthy students in their 20s. For electromyography of sit-ups and leg-raises in the supine position, 5 muscle groups of the abdomen were selected for the attachment of sensors: the upper and lower rectus abdominis, external oblique, rectus femoris, and the iliopsoas. SPSS 20.0 was used for the statistical analysis. One-way ANOVA with repeated measures of all factors was performed to verify the statistical significance of the measurements taken for the muscle activities and follow-up verification was made with the Bonferroni post hoc test.

[Results]

Sit-up and leg raise showed a significant difference. The eccentric sit-up exercise elicited a significant increase in the activation of the abdominal muscle. The leg raise and eccentric sit-up exercises elicited significant increases in the activation of hip flexor muscle.

[Conclusion]

The eccentric sit-up had the most outstanding effect on the abdominal muscles involved in stability of the trunk.

De excentriska övningarna är samma övningar fast bromsa och långsamt sänka till utgångsposition? Det verkar ju aktivera alla muskler mest oavsett övning, så det är så det är effektivast att göra sina magövningar?

Självklart tränar man rectus abdominus excentriskt för hypertrofi av den yttre bukmuskulaturen.

Har inte en situp per definition en koncentrisk excentrisk fas?
