title: The effect of open and closed kinetic chain exercises on dynamic balance ability of normal healthy adults.
abstract: [Purpose] This study investigated the effect of open and closed kinetic chain exercise on the dynamic balance ability of healthy young adults. [Subjects] Thirty-three healthy adults participated in this study. [Methods] Subjects were randomly assigned to either an open kinetic chain exercise group (n=17) or a closed kinetic chain exercise group (n=16). Both the open kinetic chain and closed kinetic chain exercise groups performed 3 sets of exercises 3 times per week for 6 weeks. Dynamic balance was measured at the beginning and end of the 6-week training period, including anterior-posterior, medial-lateral, and total displacement of the center of pressure. [Results] Both exercise groups showed improvement in balance parameters but the improvement was only statistically significant in the closed kinetic chain group. [Conclusion] Closed kinetic chain exercise appears to be more effective at improving of dynamic balance ability than open kinetic chain exercise within a 6-week training period.
