Open vs. Closed Kinetic Chain Exercises in Sedentary Individuals

Comparison of the Effects of Open Kinetic Chain and Closed Kinetic Chain Exercises on Balance and Vertical Jump Performance in Sedentary Individuals

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.
