Strength Development: Using Functional Isometrics in an Isotonic Strength Training Program

Abstract

Abstract O'Shea (1969) described the use of functional isometric training in isotonic strength training programs. Maximum isometric contractions were used at isotonic contraction sticking points, the weakest combination of joint angle and muscle length, to provide maximal overload at the critical point in an isotonic lift. The purpose of the present study was to determine if a combination of functional isometrics and standard isotonic training would be superior to a standard isotonic training program in an instructional setting. Subjects were volunteer, college males enrolled in weight training classes of a required activity program. They were assigned to two training groups. The experimental group (n =33) trained for 10 weeks, 3 days per week, using a 6-to-8RMlifting regimen on the bench press. The experimental group also followed an isometric program which consisted of 6 maximal voluntary contractions at a predetermined sticking point in the bench press(BP)exercise. A power rack was adjusted to provide ...
