The influence of nontraditional training modalities on physical performance: review of the literature.

The primary purpose of this effort was to review several forms of nontraditional (NT) training programs, including heavy lower extremity strength training, CrossFit training, kettlebell training, and agility training, and discuss the effects of these exercise regimens on physical performance. The secondary purpose was to evaluate NT fitness training programs for evidence that they may provide beneficial options to help airmen improve their fitness scores. A search of the literature for 1980-2010 was performed using the Franzello Aeromedical Library, Public Medicine, and Air Force Institute of Technology search engines. There were 50 articles located and the authors selected 29 articles that specifically addressed the primary and secondary purposes of this literature review. This review indicates that an NT training approach is warranted in the general Air Force population. Heavy leg strength training and agility training show promise in enhancing aerobic fitness and improving fitness scores, particularly among members who have difficulty passing a physical fitness test. Most of the nontraditional forms of physical training are not supported in the scientific literature, with the exception of heavy leg strength training and agility training. However, even these NT forms of training require further investigation.

Current and future cooling technologies used in preventing heat illness and improving work capacity for battlefield soldiers: review of the literature.

OBJECTIVE: The goals were to review the effectiveness of current cooling technologies used on the battlefield to reduce or to prevent heat illness in soldiers and to discuss possible alternative or improved cooling methods. METHODS: A search of the literature for 1990-2007 was performed by using the Air Force Institute of Technology and Air Force Research Laboratory search engines. RESULTS: Several current cooling technologies are modestly effective in attenuating brain and core body temperatures, but the cooling effects are not sustained and the devices present operational problems. This review indicates that some current cooling devices are effective in lowering perceived efforts and lengthening maximal exercise time but are incompatible with current demands. CONCLUSIONS: Many of the cooling methods and devices detailed in the literature are impractical for use in the field. Future research should focus on cooling technologies that are practical in the battlefield and have sustainable cooling effects.
