Minimal Equipment Training Approach to Improve Warfighter Performance

The efficacy of minimal equipment training programs with an emphasis on resistance training has seldom been assessed and compared to traditional strength training. Common training strategies include traditional high-to-moderate load resistance training and low-to-moderate load field training using minimal equipment. The benefit of traditional CT is likely due to the higher loads relative to 1-repetition maximum (1RM) utilized and overall amount of mechanical stress incurred. It is difficult to mimic this loading with minimal equipment training, which is often performed at low loads relative to 1RM. However, one strategy to improve the effectiveness of minimal equipment training may be the addition of blood flow restriction (BFR) training. Due to the relatively low loads (20-70% 1RM) of minimal equipment training, BFR training not only provides athletes with a novel training modality to elicit hypertrophic and strength adaptation but also to augment recovery as a supplemental low-damage, high-volume training method. The research design will allow for the direct comparison of minimal equipment training with and without additional BFR training to periodized CT with regard to changes in outcomes, in particular, ACFT performance.
