Acute effect of an intervention with open and closed kinetic chain muscle strength exercises on postural control and muscle power in elderly people: A randomized clinical trial.

Introduction: Aging causes changes in stance control and muscle function. However, strength exercises can mitigate these negative effects. Intervention practices are classified into open kinetic chain (OKC) and closed kinetic chain (CKC), but it is unclear whether there are differences between them regarding muscle power and balance in the older people.
