This study was undertaken to determine the relative effectiveness of static and eccentric types of exercise upon* (a) muscular strength (b) muscular volume (c) cross-transfer of strength and volume to the non- exercised arm
In this study thirty college males volunteered to participate in a program of static and eccentric exercise. The subjects were split into two groups and were equated by means of the matched pairs method. Both groups exercised twice each week for eight consecutive weeks. One group performed only static exercises, the other performed only eccentric or elongation exercises. Only the elbow flexors of the recessive arm were exercised* Each group performed three eight-second repetitions of their specific exercise.
The author hypothesized that eccentric exercise, applied with maximum exertion throughout a full range of motion, would develop a greater amount of strength in a short period of time, than would static exercise.
Both groups were acquainted, with the experimental equipment and testing procedure prior to the first test. Th first test was given at the start of the program. Test II was given after four weeks and Test III, the final test, was given at the end of the eight week prograta.
The data were collected and analyzed by means of the t technique which tests the significance of the difference between the means of paired observations of a s:oall sample. The 0.05 level of confidence was established as the rejection point of the null hypothesis.
Eccentric exercises produced a significant increase in recessive arm strength at 90 degrees of elbow flexion between Test I and Test III.
The Eccentric group was significantly superior to the Static group in recessive arm strength at 135 degrees on Test II
