The effect of ten weeks of training in water with an emphasis on central stability exercises, on balance and some selected movement functions of women volleyball players with chronic ankle sprain

Ankle sprain is a common injury in volleyball. This research aimed to investigate the effect of ten weeks of water training with emphasis on central stability exercises on balance, movement and physical performance of volleyball players with chronic ankle sprains.

60 people with ankle sprains participated in this research using the available sampling, divided into two experimental groups (30 people) and control (30 people). The subjects of the experimental group did four sessions of 60 minutes each week for ten weeks, while the control group did not experience any effective physical activity during this period. To evaluate the balance using the Biodex balance machine and to evaluate the physical performance from the aerobic performance test (stair test), agility performance test (time of the two-by-nine test), muscular endurance performance test (score of the sit-up test), Sargent's vertical jump and the three-minute staircase test was used and the pain level of the participants was measured based on the visual index of pain measurement. The data was analyzed using covariance analysis at the 0.05 level.

In this study, a significant difference was found in the balance scores, pain level and some physical fitness factors of the experimental group compared to the pre- training period (P<0.05), while no significant change was observed in the control group (P≥0.05)). In comparison with the control group, the balance scores of the experimental group showed a significant increase after ten weeks of therapeutic exercise in water.Discussion and

It seems that stabilizing exercises in water improves physical performance and reduces the severity of people with ankle sprains.
