Brief Summary

The aim of this study was to compare the effects of Open Kinetic Chain (OKC) and Closed Kinetic Chain (CKC) exercises on dynamic balance, static balance, and vertical jump performance in sedentary individuals. A total of 68 sedentary individuals voluntarily participated in this randomized controlled trial and were allocated into three groups: OKC, CKC, and a control group. Exercise programs were administered to the OKC and CKC groups for four weeks. Assessments were conducted before and after the exercise intervention. Dynamic balance was evaluated using the Y Balance Test (YBT), static balance using the Flamingo Balance Test (FBT), and vertical jump performance (VJP) using the MyJump2 mobile application.

Exercise Training; Sedentary Behavior

Outcome Measures

Primary Outcomes (3)

• Dynamic Balance

  Dynamic balance performance was assessed using the highly reliable Y Balance Test (YBT). This test has no minimum or maximum values. Higher scores indicate better dynamic stability..

  4 weeks

• Static Balance

  Static balance performance was assessed using the validated and reliable Flamingo Balance Test (FBT). This test has no minimum or maximum values. Higher scores indicate worse static balance.

  4 weeks

• Vertical Jump Performance (VJP)

  VJP assessment was performed using the MyJump2 mobile application, which has a validity rate of 99.3% when compared to force platforms. The minimum score for this test is 0, and there is no maximum score. Higher scores indicate better vertical jump/plyometric performance.

  4 weeks
