The aim of this study was to investigate the effect of 8 weeks core stability training on the Swimming speed and function of the upper limbs in young female swimmers.
To conduct this study, 24 female swimmers participated voluntarily and were randomly divided into control (Number: 12 people, Age: 16.08 ± 1.16 years, Height: 1.67 ± 0.01 m, Weight: 62.91 ± 4.37 kg) and training (Number: 12 people, Age: 16.25 ± 1.28 years, Height: 1.66 ± 0.02 m, Weight: 63.75 ± 3.88 kg) groups. After assessing their height and weight, core endurance was assessed by McGill test. Upper limb performance and closed movement chain was assessed by Y-balance function tests, and athletic performance was also assessed by the speed and number of swims 50, 100, and 200 m. After the initial evaluation, the subjects of the training group participated in an 8-week core stability training program, and the control group engaged in swimming sports activities during this period. At the end of 8 weeks, the pre-test tests were re-evaluated in this course. After all, the results related to the normality of the data were checked by Shapiro-Wilk test and after confirming the normality, parametric statistical tests of analysis of covariance and paired t-test were used to examine the differences between groups and within groups, respectively.
The results of this study show significant effects of core stability training program on 60-degree flexion tests (p˂0.001), Sorensen (p˂0.001), abdominal plank (p˂0.001), plank from the right (p˂0.001) and Planck from the left (p˂0.001) as tests related to central endurance. The results also show significant effects of this training program on the speed and number of swimming 50, 100 and 200 meters (p˂0.001) as well as upper limb function tests (p˂0.001) and closed movement chain (p˂0.001). Also, the study of the difference between the groups showed better performance of the subjects in the training group than the control group in the evaluated tests (p˂0.01).
Totally, it is shown that applying core stability training program is effective on improving motor and athletic performances of swimmers.
