 note = {Torques and angular velocities of the elbow joint were measured in two hands curl exercise with barbell in order to achieve insight into the training load of isotonic muscle strength. Subject performed lifts under four conditions of load (10.2, 14.2 kgw) and rate of lifting (24, 36 times/min). The resultant torque at the elbow was determined for one trial under each condition with the Position Sensor System. Maximal voluntary elbow flexion torque was measured in various angular velocity of elbow joint using Cybex II machine, and compared with resultant torque during arm curl exercise. For the arm curl exercise with lifting rate of 24 times/min, the resultant elbow torques had maximum at the elbow joint angle of about 60 degrees, while as for the 36 times/min trial, the resultant torques were greatest at the beginning of lifting motion. As compared with the gravitational torque, the resultant elbow joint torque was larger in the first half of the lifting motion, and smaller in the latter half. Relative value of the resultant elbow joint torque to the maximal voluntary elbow flexion torque was determined to be 70-110% over a wide range of lifting motion except one trial lifting 10.2 kgw at the rate of 24 times/min. These results suggests that in isotonic muscle strength training with barbell, appropriate choice of weight and lifting rate enables to put proper and sufficient load on the muscle to yield strength development.},
