Objective: To compare the effects of SM versus US + SM on the extensibility of the hamstring muscles in adult women.
Methods: A Randomized Controlled Clinical Trial was conducted. Fourteen women (22.3 ± 3.9 years) randomly assigned to two groups, SM (7 minutes) prior US (US + SM), n=8 and SM for 7 minutes, n=6. The differences between assessments were compared using student’s t-test; the effect of the intervention was evaluated by analysis of covariance.
Results: Significantly increased flexibility of lower limbs in both groups. In the US + SM group increased -8.75 ± 5.5; while increasing in the SM group was -3.5 ± 2.7; when comparing the groups, no statistically significant differences were found. A statistically significant increase was found in final grades in the US + SM intervention group, -5.8 (95% CI: - 10.9; -0.67p = 0.030) compared with the SM group adjusting only for baseline score.
Conclusion: A single exposure to US + SM is sufficient to enhance the gains in hamstring extensibility in adult women compared to SM.
