Power Production in Older Adults With Knee Osteoarthritis

Power Production in Older Adults With Knee Osteoarthritis Compared to Healthy Counterparts

Knee osteoarthritis is an important cause of functional disabilities at old age. Previous research has demonstrated that individuals with knee osteoarthritis have reduced knee-extensor strength in comparison to healthy individuals. However, rapid power production declines more than strength as a consequence of ageing and is more predictive of functional capacity. However, limited research has investigated whether individuals with knee osteoarthritis have reduced ability to develop strength and power rapidly on top of reduced maximal strength capacities, which is the primary aim of the current study.
