The Acute Effects Of Weighted Vest Running On Substrate Utilization And Energy Expenditure, Troy M. Purdom Mr.

Health, Exercise, and Sports Sciences ETDs

This study evaluated the effect of weighted vest running (WVR) on fatty acid oxidation (FAox) and caloric expenditure at pre-designated exercise intensities (60,65,70,75,80% VO_2max). Seventeen recreationally trained runners (9 men and 8 women) performed four separate graded exercise tests (GXT) separated by 24 hours each. The first graded exercise test (GXT) was performed to establish the workloads at specific exercise intensities. The following three GXTs tested WVR with a control (no vest), 5% body mass (BM) vest, and 10%BM vest, using 3-minute incrementally increasing steady rate stages. Indirect calorimetry was used to measure both FAox (g/min) and caloric …
