- Abstract
The purpose of this study was to evaluate the effects of a specific hip muscle training program on the functional responses of athletes undergoing reconstruction of the anterior cruciate ligament (ACL). The evaluation method consisted of 26 athletes of both genders who presented dynamic knee valgus. They were divided into two groups: a control group (CG, n = 10) and a training group (TG, n = 16). All athletes were submitted to two evaluations of variables related to vertical jump (height and power) and knee angle (KV1 and KV2) of the lower limb submitted to surgery, with the first evaluation in the pre-training and the second in the post-training. The training program for the hip musculature was performed by athletes of the training group (TG), which was carried out in 12 wks in 45-min sessions, 3 times·wk-1. The results showed that the training group (TG) only improved significantly in the vertical jump variables: Height (27.1 ± 5.6 cm vs. 28.4 ± 5.3 cm), Total Power (3056.4 ± 560.9 w vs. 3149.2 ± 549.1 w) and Relative Power (38.3 ± 3.8 vs. 39.1 ± 3.7 w) and significant reduction related to knee angles (KV1: 26 ± 3.3 vs. 15.9 ± 3.5 degrees; KV2: 25.4 ± 3.3 vs. 16.3 ± 3 degrees). The findings indicate that the training program for the athlete's hip musculature after ACL reconstruction promoted beneficial adaptations in height and jump power as well as the dynamic valgus angle.
