Descriptive Study of Strength Training Exercises to Activate the Muscles of the Operated Leg After Total Knee Replacement

"Electromyographic (EMG) activity of the vastus medialis, vastus lateralis, semitendinosus and biceps femoris muscles of the operated leg will be recorded during 6 different strength training exercises. The six exercises performed unilaterally are: seated knee extensions and leg presses in machines (gold standard exercises), and the four other exercises are: sit-to-stands, squats, straight leg raises and seated knee extensions using an elastic band.~The relative loading will be 10 repetition maximum (RM). The absolute load (kilograms) corresponding to 10 RM of the 6 strength training exercises is defined a minimum of 3 days before the day where the EMG-data are recorded. Range of motion and time under tension for each repetition will be controlled for."
