BackgroundIn hot weather, electric fans can potentially provide effective cooling for people, with lower greenhouse gas emissions and cost than air conditioning. However, international public health organisations regularly discourage fan use in temperatures higher 35°C, despite little evidence. We aimed to determine humidity-dependent temperature thresholds at which would become detrimental different age groups.MethodsWe used biophysical modelling the upper (ie, worsen heat stress) healthy...
This study assessed the accuracy of technical absorbent (TA) method for measuring local sweat rate (LSR) relative to well-established ventilated capsule (VC) during steady-state and nonsteady-state sweating using large small sample surface areas on forearm midback. Forty participants (38 males two females) cycled at 60% peak oxygen consumption 75 min in either a temperate [22.3 ± 0.9°C, 32 17% humidity (RH)] or warm (32.5 0.8°C, 29 7% RH) environment. Simultaneous bilateral comparisons 5-min...
Purpose To compare the reductions in evaporative heat loss from skin (Esk) to internal (Hfluid) induced by ice slurry (ICE) ingestion relative 37°C fluid and accompanying body temperature local thermoeffector responses during exercise warm, dry conditions (33.5°C ± 1.4°C; 23.7% 2.6% humidity [RH]). Methods Nine men cycled at approximately 55% V˙O2peak for 75 min ingested 3.2 mL·kg−1 aliquots of or ICE after 15, 30, 45 exercise. Metabolic production (M-W), rectal (Tre), mean (Tsk), whole-body...
Cold water or ice slurry ingestion during exercise seems to be an effective and practical means improve endurance performance in the heat. However, transient reductions sweating appear decrease potential for evaporative heat loss from skin by a magnitude that at least negates additional internal as cold ingested fluid warms up equilibrate with body temperature; thus explaining equivalent core temperatures fixed production irrespective of temperature. Internal transfer fluid/ice is always...
This study assesses the effects of self-dousing and foot immersion on heart rate, core temperature, thermal discomfort healthy volunteers randomized to simulated hot humid vs nonhumid conditions.
Abstract Health and performance impairments provoked by thermal stress are societal challenges geographically spreading intensifying with global warming. Yet, science may be underestimating the true impact, since no study has evaluated effects of sunlight exposure on human brain temperature function. Accordingly, in cognitively dominated combined motor-cognitive tasks markers rising brainstem were during to simulated (equal ~1000 watt/m 2 ). Acute did not affect any measures, whereas...
Two studies were performed to 1) characterize changes in local sweat rate (LSR) following fluid ingestion of different temperatures during exercise, and 2) identify the potential location thermoreceptors along gastrointestinal tract that independently modify sudomotor activity. In study 1, 12 men cycled at 50% Vo2peak for 75 min while ingesting 3.2 ml/kg 1.5°C, 37°C, or 50°C 5 before exercise; after 15, 30, 45-min exercise. 2, 8 1.5°C was delivered directly into stomach via a nasogastric...
The present study investigated muscle metabolism and fatigue during simulated elite male ice hockey match-play.Thirty U20 national team players completed an experimental game comprising three periods of 8 × 1-min shifts separated by 2-min recovery intervals. Two vastus lateralis biopsies were obtained either the (n = 7) or pregame postgame 6). Venous blood samples drawn at end first last 14). Activity pattern physiological responses continuously monitored using local positioning system heart...
Heat acclimation is associated with plasma volume (PV) expansion that occurs within the first week of exposure. However, prolonged effects on hemoglobin mass (Hbmass) are unclear as intervention periods in previous studies have not allowed sufficient time for erythropoiesis to manifest. Therefore, Hbmass, intravascular volumes, and blood (BV)-regulating hormones were assessed 5½ weeks exercise-heat (HEAT) or matched training cold conditions (CON) 21 male cyclists [(mean ± SD) age: 38 9...
Menthol topical application and mouth rinsing are ergogenic in hot environments, improving performance perception, with differing effects on body temperature regulation. Consequently, athletes federations beginning to explore the possible benefits elite sport for Tokyo 2021 Olympics, which will take place (~ 31 °C), humid (70% RH) conditions. There is no clear consensus safe effective menthol use athletes, practitioners, or researchers. The present study addressed this shortfall by producing...
We sought to determine the independent influence of running economy (RE) and aerobic fitness [maximum oxygen consumption (V̇O 2max)] on thermoregulatory responses during treadmill by conducting two studies. In study 1, seven high (HI-FIT: 61 ± 5 ml O2 · kg(-1) min(-1)) low (LO-FIT: 45 4 V̇O 2max males matched for physical characteristics RE 200 21; LO-FIT: 18 km(-1)) ran 60 min at 1) 60%V̇O 2) a fixed metabolic heat production (Hprod) 640 W. 2, (HI-ECO: 189 15.3 (LO-ECO: 222 10 3; LO-ECO: 7...
Background: Within the context of COVID-19 pandemic, WHO endorses facemask use to limit aerosol-spreading novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, concerns have been raised regarding facemask-associated dyspnea, thermal distress and self-reported impairment cognition. Accordingly, we tested how facemask-use affects motor-cognitive performances relevance for occupational safety. We hypothesized that mask would affect cognitively dominated discomfort, but...
Background: Heat waves caused by climate change are increasingly challenging the wellbeing of individuals across lifespan. Current efforts to understand thermal perceptions and behaviours people throughout lifespan during heat limited. Methods: Since June 2021, Active Heatwave project has been recruiting households better how perceive, cope, behave waves. Using our novel web platform, participants were prompted answer Alert Survey on days when a geolocation corresponded broadcasted local...
Successful implementation of cooling strategies obviously depends on identifying effective interventions, but in industrial settings, it is equally important to consider feasibility and economic viability. Many interventions are available, the decision processes affecting adoption by end-users not well elucidated. We therefore arranged two series meetings with stakeholders identify knowledge gaps, receive feedback proposed discuss factors heat-health interventions. This included four...
