Description
The purpose of this study was to examine the influence of knowing versus not knowing the weight being lifted and its effects on a five repetition maximum (5-RM) during squat in male collegiate athletes. This study received approval from the Hanover College Institutional Review Board with regard to the use of human subjects.
Methods: Ten male subjects volunteered to participate. A baseline 5-RM squat was tested for each individual. From their 5-RM a 1-RM was calculated using the formula (weight/ (1.0278-(.0278*reps))). Subjects were then assigned to either the control (see weight) or experimental (covered weight) group. Three more trials were then completed in random order (retest baseline 5-RM, 6% above baseline 5RM and 4% below baseline 5RM).
Results and discussion: Data collection is ongoing. However, pilot data suggests that individuals were able to lift more weight when they did not know the specific amount being lifted. When re-testing subjects in the experimental group on their baseline 5-RM weight, they completed on average two extra reps which has increased their calculated 1-RM. Re-testing the baseline 5-RM in the control group has led to no increase in calculated 1-RM.
