Muscular strength: greatest amount of force that a muscle can produce during a single maximum effort. Muscular endurance: when you lift more total for the reps you do, rather than lift once only. Isometric: usually measured with a spring loaded dynamometer or cable tensiometer: dynamic: measured using free weights or machines like universal gym. Isokinetic contractions: measured via isokinetic dynamometer as the torque developed in a muscle at defined and controlled speeds of contractions. Machines to measure strength testing biodex and kin-com. Procedure: adjust the handle so that the second joint of the fingers fits on top of the handle. Set the needle indicator at zero: the subject, while standing, takes the dynamometer in chosen hand about 6-12 inches away from the thigh with the arm straight, the subject vigorously squeezes the dynamometer. Hand and dynamometer should not touch anything when test is being administered: test right hand and left hand twice each for nearest kg, 30sec rest between attempts.
