Effects of Adding End-Range Isometric Holds to Isotonic Knee Extensor Training on Isokinetic Performance in Sedentary Adults: A Randomized Controlled Trial

This randomized controlled trial investigated the effects of a specific training protocol. The main objective was to determine how adding end-range isometric holds influences isokinetic performance. The training focused on knee extensors, which are the muscles responsible for straightening the leg. The study participants were sedentary adults, meaning individuals with low levels of physical activity. The study compared two intervention groups: one performing only isotonic exercises, and another adding isometric holds to them. The measured parameters included quadriceps muscle strength and overall isokinetic performance. The research was sponsored by Yeditepe University and has already been completed.
