Comparison Of Isometric And Isokinetic Strength Training Effects On Physical Performance In Athletes With Knee Pain

"Isokinetic strength program included strength training at 5 different velocities from slow to fast. Participants were trained on speed of 30°/sec, 90°/sec, 150°/sec, 210°/sec and 270°/sec. Flexion and extension movements were completed with 5 repetitions at each speed.~Participants of isometric strength training group performed isometric contractions at 30°, 45° and 60° of knee flexion with five repetitions at each angle for both hamstring and quadriceps."
