Abstract

A study of isokinetic exercise and isotonic variable-resistance training divided 12 individuals into four groups: 1) control; 2) isotonic variable-resistance training; 3) low-speed isokinetic (5, 10, and 15 rpm); and 4) highspeed isokinetic training (30, 40, and 50 rpm). All exercised groups showed good gains in strength when tested isometrically, isotonically, and isokineticallly. However, when the individuals were tested for motor performance, the high-speed isokinetic group dominated (5.38 gain in the vertical jump versus3.87 for the slow isokinetic, and 1.57 for the isotonic variable resistance9.14 gain in the standing broadjump versus 0.42 and 0.28 ; and 10.11 gain in the 40-yard dash versus 1.12 and 1.35 ). Training should be specific in all training and rehabilitation programs, with the athletepatient training in the manner most similar to his athletic event or performance. Verf.-Referat
