The effects of two strength training programs through a range of motion

Includes bibliographical references (pages 47-51)The purpose of this investigation was to ascertain\ud which strength training method is most effective in developing\ud strength through a full range of motion, The ExerGenie\ud or a modified DeLorme traditional method of weight\ud lifting.\ud This study utilized the facilities located at Faith\ud Baptist Junior High~School in Canoga Park, California.\ud The subjects tested were thirty junior high school boys in\ud grades seven and eight enrolled in a general physical education\ud class. The subjects were divided into two equated\ud experimental groups. Group A trained using the Exer-Genie\ud technique, and Group B trained using a modified Delorme\ud technique. The subjects in both groups exercised for an\ud equated work period of thirty-five seconds on Monday,\ud Wednesday, and Friday during a six-week period. A familiarization\ud and pre-test was administered prior to the sixweek\ud work period; a mid-test was administered at the end of the third week; and a post-test was administered following\ud the completion of the study to ascertain the amount of\ud strength gained by the subjects in both experimental groups.,\ud The subjects were measured with the cable tensiometer at\ud three angles in a range of motion; the angles were 40, 80,\ud and 120 degrees.\ud The findings of this study indicate that both Group\ud A and Group B gained strength within their group at the\ud angles of 120 and 80 degrees. The analysis of variance\ud indicated that no differences occurred between Groups A\ud and B at the angles of 120 and 80 degrees. There was a\ud difference indicated at the 40 degree angle, but, due to thj\ud pre-score differences, this finding could not be considered.\ud Since the hypothesis was shown to be tenable,\ud (wherein the data are acceptable at the angle of 120 and\ud 80 degrees) it was concluded that after six weeks of training,\ud the Exer-Genie and modified DeLorme techniques are\ud equally effective for strength development through a full\ud range of motion as measured in this investigation
