Effect of Single-Leg Stance and Jumping exercises on improving functional balance among female athletes.

INTERVENTION: The effects of the Single‐Leg Stance (SLS) and Jumping exercises (JE) have been evaluated and shown reduce in injury incidence significantly. However, the effects of the SLS or JE on improving functional balance have not been investigated and yet may be important. Therefore, we will evaluate the effect of SLS and JE on improving functional balance compared to no intervention, among amateur female athletes. Methods: female amateur athletes aged 19–25 years will be randomly assigned to SLS and JE intervention group (n=20 athletes), SLS intervention group (n=20 athletes), JE intervention group (n=20 athletes) or a control group (n= 20 athletes). SLS+JE intervention group and SLS intervention group will perform: Single ‐leg stance hold the ball This exercise improves leg muscle coordination and balance. Assume the starting position, standing on one leg and holding the ball in front of you in both hands. Bend your knee and hip slightly so that your upper body leans forwards slightly. When viewed from the front, the hip, knee and foot of your supporting leg are in a straight line. Hold the raised leg slightly behind the supporting leg. During this exercise, hold your balance and keep your body weight on the ball of your foot. Hold for 30 seconds, change legs and repeat. The exercise can be made more difficult by lifting the heel from the ground slightly or passing the ball around your waist and / or under your other knee. Repetitions: 2 sets (30 sec. on each leg) Single ‐leg balance throwing ball with partner This exercise improves leg muscle coordination and balance. Assume the starting position, standing 2 – 3 meters apart from your partner, with each of you standing on one leg. Bend your knee and hip slightly so that your upper body leans forwards slightly. When viewed from the front, the hip, knee and foot of your supporting leg are in a straight line. Hold the raised leg slightly behind the supporting leg. During this exerci CONDITION: Musculoskeletal ‐ Normal musculoskeletal and cartilage development and function Sports related injuries ; ; Sports related injuries; PRIMARY OUTCOME: All groups will perform the pre‐ post intervention test using Biodex Balance Stability System . The primary outcome measure will be balance.[Single assessment after 6 weeks] SECONDARY OUTCOME: Incidence of lower extremity injuries.. ; Injury is defined according to a consensus statement on injury definitions and data collection procedures in soccer studies; an injury will be recorded if it caused the player to be unable to completely participate in the following match or training session. ; This data will be collected using Sports Medicine Australia injury reporting form ; http://websites.sportstg.com/get_file.cgi?id=2308813[Assessed weekly for 6 weeks] INCLUSION CRITERIA: Female athletes
