           The Impact of a Weighted Warmup on 1-Mile Run Performance        Ashley Y. Lesniak, Mason S. Martin, Curt B. Dixon, FACSM. Lock Haven University, Lock Haven, PA  PURPOSE: To investigate the impact of a weighted warmup on 1-mile run performance. METHODS: 7 males (Age: 20.9 ± 0.9 yr; Height: 175.5 ± 7.0 cm; Weight: 80.8 ± 11.4 kg; Body Fat: 12.8 ± 4.2%) and 5 females (Age: 22.4 ± 3.8 yr; Height: 167.9 ± 9.0 cm; Weight: 65.1 ± 10.1 kg; Body Fat: 20.5 ± 2.6%) participated in the study. On four separate days, subjects completed a 15 min warmup walking on a motorized treadmill, at a predetermined unloaded intensity equal to 5 METs, followed by a 1-mile run.  Warmup sessions included an unloaded (UL) trial, which served as the control, and wearing a light load (LL; 24 lb), moderate load (ML; 48 lb) and heavy load (HL; 80 lb) weighted vest. The testing order of the weighted warmup trials was determined by counterbalanced assignment.  Following the 15 min warmup, subjects were asked to complete an unloaded 1-mile run as quickly as possible. Ratings of Perceived Exertion (RPE) were assessed every minute and heart rate (HR) was measured continuously throughout the 1-mile run and averaged for statistical comparison. Repeated Measures ANOVAs were used to compare the different weighted conditions.  RESULTS: 1-mile run time (UL: 9.4 ± 0.9, LL: 9.0 ± 1.3, ML: 9.4 ± 1.3, HL: 9.0 ± 1.3 min; p = .340) and average RPE (UL: 11.6 ± 1.9, LL: 10.9 ± 2.3, ML: 10.8 ± 2.4, HL: 11.2 ± 2.2; p = .191) were not significantly different between warmup conditions. Average HR, during the 1-mile run, was significantly higher after the HL warmup (167.3 ± 10.7 b·min-1) when compared to the UL (161.9 ± 8.9 b·min-1; p = .013) and ML (159.0 ± 13.3 b·min-1; p = .019) warmup trials. CONCLUSION: The 15-minute weighted warmup sessions did not impact run performance or perception of effort.
