| Summary: | 碩士 === 高雄醫學大學 === 運動醫學系碩士班 === 104 === Background: More and more dancers of cheerleading in Taiwan got pretty good grades on the international competitions. These cheerleading dancers, not only had complete training since they were young is necessary, but also, using the scientific exercising test is helpful to increase the grades of the competition. Core muscle and stable ability play an important role in performing an act and exercising performance. Pilates is one way to train the core muscle. However, most of researches in Pilates studied how Pilates improves back pain problem or increase the muscular endurance’s performance on four limbs. To our best knowledge, there is no related research investigates regarding the efficacy on performing an act and the exercising performance by using Pilates on cheerleading dancers
Purpose: We aimed to investigate the cheerleading dancers’ quality of perform an act, muscular endurance’s performance, explosive force, and ability of balance influence by the eight-week Pilates training.
Method: The participants in this study included thirty college cheerleading dancers from two different colleges. We randomly allocated one school’s cheerleading dancers (15 participants) to be the training group, and another school’s cheerleading dancers (15 participants) to be the control group. Before the experiment, participants provided voluntary written informed consent to participate in the experiment. The training group’s participants had not only their regular practicing, but also additionally included the Pilates training class from a licensed Pilates instructor, three times a week and fifty minutes a time for eight weeks; the control group’s participants only maintain their regular practicing. We further assessed the health interview, weight and body fat test, and functional movement screen (including deep squat, hurdle step, active straight leg raise, in-line lunge, active straight leg raise movement pattern, trunk stability push up, rotary stability, vertical jump, Y balance test, isometric endurance of trunk muscles, plank, and side plank) on both pre-test and post-test.
Result: In the pre-test, there was no significant different baseline data between dancers in training group (height 158.2 ± 12.0 cm; weight 52.39 ± 4.6 kg; BMI 20.19 ± 1.45; dancing years 10.4 ± 1.35) and control group (height 159.5 ± 4.5 cm; weight 54.71 ± 4.1 kg; BMI 21.46 ± 1.99; dancing years 10.33 ± 1.23). The post-test of the training group in the FMS had a significant improvement. However, the control group did rarely improvement. The training group in hurdle step (pre-test: 2 ± 0.53 versus post-test: 2.73 ± 0.46, p < .001), trunk stability push up (pre-test: 1.73 ± 0.46 versus post-test: 2.2 ± 0.41, p = .004) rotary stability (pre-test: 2 versus post-test: 2.67 ± 0.49, p < .001), totally scores (pre-test: 16.4 ± 1.24 versus post-test: 19, p < .001) were all achieving the significant differences. Furthermore, the asymmetrical ratio on hurdle step and in-line lunge was improved by 67% and 100%, respectively. However, no one has improvement in the control group. Besides, the average of vertical jump in the training group was 39 ± 6.1 cm. It is clearly better than the scores on the pre-test, which is 32.6 ± 4.43 cm, and the p indicated < .001. Moreover, the training group’s effect size reached the moderate efficacy (0.52), but the control group only has the modest difference (0.01). In the Y balance test, the training group had a slight improvement, but did not show the significant difference (pre-test is 78.23 ± 7.05 cm, post-test is 82.83 ± 6.5 cm).
Conclusion: Pilates improves significantly the functional movement screen scores and the bilateral asymmetrical problem after eight weeks Pilates training. Moreover, Pilates is also helpful to increase the vertical jump, and the isometric endurance of abdominal and trunk muscles.
