Effect of isometric quadriceps strengthening exercise at multiple angles in knee joint among normal adults.
Introduction:Strengthening exercises have been routinely used in persons with orthopaedic problems and athletes to increase force production or minimize muscle imbalance and joint injuries.Many studies have reported that isometric contractions can rapidly increases strength in quadriceps muscle.
