The purpose of the present study was to compare the heat strain while wearing nuclear, biological, and chemical (NBC) protective clothing following a hot-wet (HW) or hot-dry (HD) heat acclimation protocol. Twenty-two males were assigned to groups HW (n = 7), HD (n = 8), or control (C, n = 7). Subjects were evaluated during continuous treadmill walking while wearing lightweight combat clothing and during intermittent exercise while wearing the NBC protective clothing. While wearing Combat…

Heat acclimation, aerobic fitness, and hydration effects on tolerance during uncompensable heat stress.
TLDR
It was concluded that exercise-heat tolerance in this uncompensable heat-stress environment is not influenced by short-term heat acclimation but is significantly improved by long-term aerobic fitness.
Heat Strain in Personal Protective Clothing: Challenges and Intervention Strategies
Humans rely on sweat evaporation during exercise in the heat to promote cooling and to maintain thermal homeostasis. In protective clothing, however, sweat evaporation is severely hampered and this…

Encapsulated environment.
TLDR
Individuals with low body fatness who perform regular aerobic exercise have tolerance times in PPC that exceed those of their sedentary counterparts by as much as 100% due to lower resting temperature, the higher Tc tolerated at exhaustion and a slower increase in Tc during exercise, however, questions remain about the importance of activity levels, exercise intensity, cold water ingestion, and plasma volume expansion for thermotolerance.
Effectiveness of exercise-heat acclimation for preventing heat illness in the workplace.
TLDR
As a practical means of acclimatizing the body to heat stress, daily aerobic exercise training is recommended since thermoregulatory capacity and blood volume increase with physical fitness.
Effects of dehydration, hypohydration, and hyperhydration on tolerance during uncompensable heat stress.
TLDR
It was concluded that prior exercise leading to levels of dehydration to 2.3% of body weight, together with subsequent fluid restriction during exposure to uncompensable heat stress, impaired TT while wearing the NBC protective clothing.
The Thermophysiology of Uncompensable Heat Stress
TLDR
The impact of hydration status, aerobic fitness, endurance training, heat acclimation, gender, menstrual cycle, oral contraceptive use, body composition and circadian rhythm on heat tolerance while wearing protective clothing in hot environments is discussed.
Efficacy of 1 and 5 mg Doses of Melatonin on Heat Tolerance While Wearing NBC Protective Clothing.
TLDR
The findings from 2 studies which examined whether the reported hypothermic effect of melatonin ingestion increased tolerance to the heat stress of wearing NBC protective clothing were summarized.
Older firefighters are susceptible to age-related impairments in heat dissipation.
TLDR
Older firefighters and age-matched nonfirefighters demonstrate similar HL and S during work in the heat, and HL is significantly reduced in older compared to younger firefighters during exercise in both warm/dry and warm/humid conditions.
Physiological Responses to Overdressing and Exercise-Heat Stress in Trained Runners
TLDR
The idea that overdressing during exercise in a temperate environment may produce the high Tre, Tsk, HR, and SR necessary for adaptation, but these responses do not match those in hot, dry environments is supported.

TLDR
Beneficial increases in evaporation were achievable by increasing skin wettedness only when there was a consistent drippage, which differed from one body area to another and from one subject to another.

Variability of time to exhaustion during submaximal exercise.
TLDR
Due to the variability in TE that may be observed with males of average fitness, it is concluded that TE should not be the only dependent measure used to evaluate treatment effects during submaximal exercise.

Respiratory weight losses during exercise.
TLDR
For exercise at oxygen consumption rates exceeding 1.5 L/min in a dry environment with a water vapor pressure of 10 mm Hg, the total rate of weight loss via the respiratory tract is on the order of 2-5 g/min.
Training-induced hypervolemia: lack of an effect on oxygen utilization during exercise.
TLDR
It is concluded that hypervolemia induced by short-term exercise training does not affect oxygen consumption either during sub-maximal or maximal exercise.
Effects of short-term training on cardiac function during prolonged exercise.
TLDR
It is proposed that the increase in Q serves primarily to increase muscle blood flow and maintain arterial O2 delivery, while the altered cardiodynamic behavior serves to increase cardiac reserve, providing a greater tolerance to prolonged heavy exercise.
Relationship of regional body composition to bone mineral density in college females.
TLDR
Looking at relationships between regional body composition and bone mineral density (BMD) in college females through dual energy x-ray absorptiometry, regional LTM appears to be a better predictor of BMD than regional fat mass.
