This study was undertaken to determine the changes elicited by the use of the Sxer-genis exerciser es e sprint-start training device.
Ten freshman end varsity sprinters who were members of the University of North Dakota intercollegiate track teem served as subjects. The control group participated in the initial and final testing and followed the regularly scheduled track training and practice. The experimental group participated in similar tasting and training, but also worked two or three times per week on s controlled Exer-genie program.
The initial and final tests involved six timed trials for the twenty-yard dash out of starting blocks and six trials with the reaction timer. The mean time for each test became the subject*# score for that test. These scores were used to equate the groups using the matched pairs msthod.
The significance of difference between the initial and final test means for each measurement within each group was tested by the "t” technique for correlated scores from small samples. Rejection of the null hypotheela wee assumed at the .05 level of confidence.
Comparisons were made between groups for each maaaurement to establish whether there was any significant difference, for this purpose the standard error of the difference between weens of correlated sawplea was tested for significance at the .OS level of confidence.
the conclusions drawn from this study worst 1. neither the control group nor Idle experimental group atede significant improvement et the .OS level of confidence la starting speed for the twenty yard sprint start. 2. In compering the control group and the experimental group, no significant differences were found at the criterion .05 level in sprint start speed or In reaction time. 3. The experimental training program produced no significant changes et the .05 level In the ability of the subjects to Improve upon their apeed In the first twenty yards of s sprint race. 4. The effect of the experimental training upon reaction time was not significant at the .OS level of confidence end the differences that did occur were negligible.
