 | The United States Army Research Institute of Environmental Medicine (USARIEM) celebrated its 50th anniversary on July 1, 2011. This article reviews its history, evolution, and transition of its research programs as well as its scientific and military accomplishments, emphasizing the past 25 yr. During the 1990s, USARIEM published a series of pocket guides providing guidance for sustaining Warfighter health and performance in Southwest Asia, Somalia, the former Republic of Yugoslavia, ... |

| Probiotic-containing foods are consumed to enhance gastrointestinal (GI) health and immune function. How storage of probiotic-containing foods affects colonization and persistence of probiotics in the GI tract after the stored foods are consumed is undefined. Similarly, the amount or dose of probiotics that must be consumed to achieve colonization and persistence of probiotics in the GI tract is not known. Volunteers ate fresh pudding with Lactobacillus reuteri DSM17938 (L. reuteri; ... |

|
| Inadequate energy intake induces changes in endogenous glucose production (GP) to preserve muscle mass. Whether addition provision of dietary protein modulates GP response to energy deficit is unclear. The objective was to determine whether exercise-induced energy deficit effects on glucose metabolism are mitigated by increased dietary protein. Methods:Nineteen men ([mean +/- SD] 23 +/- 2 y, VO(sub2 peak) 59 +/- 5 ml-kg(exp-1)min(exp-1)) were divided into three groups, two consuming moderate ... |

|
| Excess weight is associated with negative health outcomes. Meal replacements are effective in promoting favorable body composition changes in civilian populations, however, their efficacy with military service members who have unique lifestyles is unknown. The objective of this randomized controlled trial was to determine the efficacy of the Army's education-based, weight-management program, Weigh to Stay, with and without meal replacements for improving blood lipids and to promote weight and body ... |

|
| Two experiments were performed to examine how different proteins in a carbohydrate-,protein beverage affect postprandial amino acid (AA), glucose, and insulin responses. In one, volunteers drank 3 beverages in separate trials, each differing in protein type. Ten additional volunteers consumed the same drinks after 60 min of varying-intensity exercise. Blood glucose, insulin, glucose-dependent insulinotrophic polypeptide, and AAs were measured after consumption. Branched-chain AA concentrations peaked at 30 min and did ... |

|
| The Department of Defense (DoD) has mandated the development of a system to collect and manage data on the weight, percent body fat (%BF), and fitness of all military personnel. This project aimed to accomplish the following: (1) develop a computerized weight and fitness database to track individuals and Army units over time, allowing cross-sectional and longitudinal evaluations; and (2) test the computerized system for feasibility and integrity of data ... |

|
| This paper reviews the experimental findings describing human physiological adaptations induced by chronic or repeated cold exposure. The adaptations are classified as acclimatization when they occur naturally as a result of climatic or seasonal changes in temperature, or as acclimation when they occur in response to artificial or experimental manipulations of the ambient thermal environment. Three different patterns of cold adaptation can he identified. Habituation, the most common pattern observed ... |

|
| The purposes of this study were the following: to determine whether erythrocyte infusion alters the control of thermoregulatory sweating and to demonstrate how increases and decreases of both plasma toxicity and blood volume influence the thermoregulatory control parameters of threshold temperature and sweating sensitivity. Six non-heat-acclimated and five heat-acclimated males attempted heat stress tests (HSTs) both before and shortly after (48-96 h) autologous erythrocyte infusion. The non-heat acclimated subjects were ... |

|
| Thermoregulatory responses during heat acclimation were compared between nine young and nine middle-aged men who were matched for body weight, surface area, surface area-to-weight ratio, percent body fat, and maximal aerobic power. After evaluation in a comfortable environment, the men were heat acclimated by treadmill walking for two 50-min exercise bouts separated by 10 min of rest for 10 consecutive days in a hot dry environment. During the first day ... |
