A comparative study of a traditional isometric conditioning program versus a weighted helmet conditioning program on cervical strength.

Abstract

STATEMENT OF THE PROBLEM: The problems of this investigation were to determine: (1) whether or not there is any difference in cervical strength when an isometric program is used in comparison with a weighted helmet conditioning program, and (2) whether or not within the weighted helmet conditioning program, three sets of three repetitions at 90% of maximum weight versus three sets of ten repetitions at 50% of maximum weight produce any significant difference in cervical strength gain criteria in the ranges of movement of flexion and extension. SUMMARY OF PROCEDURE: The test and retest method and a comparison of pre and post-test were used in this study. Training programs consisted of one group performing isometric exercises and two groups performing two different isotonic training methods. The duration of the program was six weeks, with sessions each Monday, Wednesday and Friday. REVIEW OF CONCLUSIONS: 1. Isotonic exercise remains superior to isometric exercise for increasing strength. 2. A high resistance-low repetition conditioning program is more efficient than a low resistance-high repetition conditioning program in increasing cervical (neck) strength in the range of movement of extension.
