Weighted running: Effect on impact and oxygen consumption

The purpose of this study was to investigate if runners adjust running style based on impact magnitude instead of running economy while wearing 30% added trunk weight. Runners ran overground at a self-selected pace with and without 30% added trunk weight. Impact magnitudes and other force parameters were analyzed. Runners also ran on a treadmill with 30% added trunk weight at their preferred stride frequency (PSF) and at +/-10% PSF. Oxygen consumption (VO2) and PSF were recorded. VO2 and PSF were greater during nonweighted compared to weighted running (p < 0.05). During weighted running, VO2 was greater when running at the -10% PSF than the PSF, but not different than the +10% PSF. The slightly greater stride frequency during weighted running compared to nonweighted running may be a strategy to keep F1 magnitudes constant concurrent with maintaining and economical gait pattern. It was concluded that individuals optimized on VO2 and impact concurrently.
