Aerobic fitness as a parameter of importance for labour loss in the heat
(2021)Objectives: To derive an empirical model for the impact of aerobic fitness (maximal oxygen consumption; V̇O2max in mL∙kg−1∙min−1) on physical work capacity (PWC) in the heat. Design: Prospective, repeated measures. Methods: ... -
Aging Impairs Whole-Body Heat Loss in Women under Both Dry and Humid Heat Stress
(2017)Purpose This study was designed to determine whether age-related impairments in whole-body heat loss, which are known to exist in dry heat, also occur in humid heat in women. Methods To evaluate this possibility, 10 young ... -
Direct exposure of the head to solar heat radiation impairs motor-cognitive performance
(2020)Health and performance impairments provoked by thermal stress are societal challenges geographically spreading and intensifying with global warming. Yet, science may be underestimating the true impact, since no study has ... -
Do the threshold limit values for work in hot conditions adequately protect workers?
(2016)Purpose We evaluated core temperature responses and the change in body heat content (ΔH b) during work performed according to the ACGIH threshold limit values (TLV) for heat stress, which are designed to ensure a stable ... -
The effect of plasma osmolality and baroreceptor loading status on postexercise heat loss responses
(2016)We examined the separate and combined effects of plasma osmolality and baroreceptor loading status on postexercise heat loss responses. Nine young males completed a 45-min treadmill exercise protocol at 58 ± 2% V O2 peak, ... -
Evidence for age-related differences in heat acclimatisation responsiveness
(2020)New Findings: What is the central question of this study? Repeated heat exposure during the summer months can enhance heat loss in humans (seasonal heat acclimatisation), but does the magnitude of that enhancement differ ... -
Heart rate variability during high heat stress: A comparison between young and older adults with and without type 2 diabetes
(2016)We examined whether older individuals with and without type 2 diabetes (T2D) experience differences in heart rate variability (HRV) during a 3-hour exposure to high heat stress compared to young adults. Young (YOUNG; n=22; ... -
Impact of pre-cooling therapy on the physical performance and functional capacity of multiple sclerosis patients: A systematic review
(2019)Patients with multiple sclerosis experience many complications that gradually lead them to comorbidity and disability. Exercise could prevent and ameliorate the symptoms that comorbidity or inactivity generate. However, ... -
Physical characteristics cannot be used to predict cooling time using cold-water immersion as a treatment for exertional hyperthermia
(2018)We examined if physical characteristics could be used to predict cooling time during cold water immersion (CWI, 2 °C) following exertional hyperthermia (rectal temperature ≥39.5 °C) in a physically heterogeneous group of ... -
Quantifying the impact of heat on human physical work capacity; part II: the observed interaction of air velocity with temperature, humidity, sweat rate, and clothing is not captured by most heat stress indices
(2022)Increasing air movement can alleviate or exacerbate occupational heat strain, but the impact is not well defined across a wide range of hot environments, with different clothing levels. Therefore, we combined a large ... -
Quantifying the impact of heat on human physical work capacity; part IV: interactions between work duration and heat stress severity
(2022)High workplace temperatures negatively impact physical work capacity (PWC). Although PWC loss models with heat based on 1-h exposures are available, it is unclear if further adjustments are required to accommodate repeated ... -
The recommended threshold limit values for heat exposure fail to maintain body core temperature within safe limits in older working adults
(2017)Purpose: The American Conference of Governmental and Industrial Hygienists (ACGIH®) Threshold Limit Values (TLV® guidelines) for work in the heat consist of work-rest (WR) allocations designed to ensure a stable core ... -
Revisiting the influence of individual factors on heat exchange during exercise in dry heat using direct calorimetry
(2019)New Findings: What is the central question of this study? The aim was to identify the greatest contributor(s) to the variation in whole-body heat exchange, as assessed using direct calorimetry, among young men and women ... -
Separate and combined effects of cold dialysis and intradialytic exercise on the thermoregulatory responses of hemodialysis patients: a randomized-cross-over study
(2020)Background: The separate and combined effects of intradialytic exercise training (IET) and cold dialysis (CD) on patient thermoregulation remain unknown. This study assessed the thermoregulatory responses of hemodialysis ...
