Nine men (25.11 +/- 1.16 years) performed 3 different test sessions. In the control session, subjects performed a 10-second sprint cycle test and 1 repetition maximum (1RM) in the back squat. The 5-minute test session consisted of 10 x 1 repetition in the parallel back squat exercise at 90% of their 1RM, 5 minutes of rest, and then a 10-second sprint cycle test. The 20-minute test session consisted of the same test protocol as the 5-minute test session except that the subjects rested for 20-minutes prior to the sprint cycle test. Significant differences were found in average power and average power relative to body weight (F = 5.684, p = 0.014, and F = 1.258, p = 0.006, respectively) for the 5-minute test session. The authors conclude that this particular squat protocol could have a potential carry-over effect into improvements in 100-m sprint times when performing the squats 5-minutes prior to performance.
