 | An evaluation of all new tactical vehicles and aircraft is required to assess potential whole-body vibration (WBV) health hazards to crewmembers. As requested by the U.S. Army Environmental Hygiene Agency (USAEHA), a health hazard assessment (HHA) was performed by the U.S. Army Aeromedical Research Laboratory (USAARL) on the M1070 Heavy Equipment Transporter System (HETS). The HETS was tested on three cross-country courses at Aberdeen Proving Ground (APG), MD, by the ... |

| Since their return from deployment in the Persian Gulf war, many U.S. troops have complained of health problems that they believe result from their service in the gulf region. Research has shown that U.S. troops were exposed before, during, and after the war to a variety of substances that are potentially hazardous. These include occupational hazards (such as the extensive use of diesel fuel as a sand suppressant in and ... |

| Injuries due to exercise and training are cammon, particularly in Army populations. Few studies have examined the relationship between race and such injuries. Eight-hundred and sixty-one male and female Army trainees were followed over their 8 week Basic training course. This program, with its standardized activities and similar risk exposures provides a unique study environment. Demographic, body composition and physical fitness characteristics were measured on all volunteers. Fifty-two percent were ... |

| Injuries are common among those who engage in vigorous physical activity, particularly among military Basic Trainees. This is a unique population for the study of injuries as many potential confounders are controlled by the highly standardized environment. Previous studies of injury have identified body composition, physical fitness and gender as risk factors. Studies also indicate that women enter the Army less physically fit than their male counterparts. Hence, it is ... |

| Cell membrane leakage of sodium and potassium ions results in an energy drain at the cellular level as active transport activity must increase to maintain the membrane potential. This membrane permeability increases as body temperature rises, a result of an increase in the kinetic energy of the ions. Thermal stress and the resultant increased cell membrane permeability poses a challenge to the cell to maintain homeostasis and may contribute to ... |

|
| Cyanide has been shown to affect calcium homeostasis. Cyanide causes an increase in intracellular Ca(2+) concentration in PC12 cells, rabbit carotid body chemoreceptors, rat ventricular myocytes, rat osteoclasts, and Leishmania donovani promastigotes. In PC12 cells the increase is believed to be activated by voltage-gated Ca(2+) channels. In rabbit carotid body chemoreceptors it is due to inhibition of Na(+)/Ca(2+) exchange. In Leishmania donovani promastigotes, it results from a Ca(2+) mobilization from ... |

| This report discusses research issues identified by two National Research Council studies on human performance models and proposes a new approach to model development, called the method of successive approximation, to address these issues. Successive approximation is an incremental approach to human performance process model development. During each increment of development, a complete human performance model is built. Initial models, however, are limited in the behavior they can represent. Subsequent ... |

|
| Protective clothing imposes significant physiological and psychological stresses on the human body and may limit work tolerance, especially in hot environments. The additional strains imposed by protective clothing arise mainly because it is difficult for sweat to evaporate through relatively impermeable fabrics. Endurance training is a commonly adopted tactic to improve tolerance times when individuals must work in the heat. Potential benefits include improved physical fitness, increased sweating, and expanded ... |

| Several published reports have implied that long-term, low-level exposure to radio-frequency radiation (RFR) may influence the growth and/or differentiation of mammalian cells in vivo. Specifically, the issue involves whether or not such RFR exposure can cause cells to differentiate into an invasive form (tumor induction) or can act as a promoter of tumor expression. To address this issue, the United States Air Force sponsors a project involving long-term exposure of ... |

| In the weightless state astronauts do a substantial amount of work with their arms and hands. Upper body exercise elicits a peak oxygen uptake approximately 70% of that obtained during lower body exercise; in addition, upper body exercise requires a greater oxygen uptake at a given power output than low body exercise. Therefore, when performing exercise at a given power output, both the absolute and relative exercise intensity is greater ... |
