Ice Slurry Ingestion Leads to a Lower Net Heat Loss during Exercise in the Heat
THERMOREGULATION PARTITIONAL CALORIMETRY SKIN BLOOD FLOW
2017/4/13
Purpose: To compare the reductions in evaporative heat loss from the skin (Esk) to internal heat loss (Hfluid) induced by ice slurry (ICE) ingestion relative to 37°C fluid and the accompanying body te...
Short Duration Heat Acclimation in Australian Football Players
Core temperature thermoregulation high intensity interval training adaptation metabolism
2016/3/11
This study examined if five sessions of short duration (27 min), high intensity, interval training (HIIT) in the heat over a nine day period would induce heat acclimation in Australian football (AF) p...
Expression of Heat Shock Proteins (HSPs) in Aged Skeletal Muscles Depends on the Frequency and Duration of Exercise Training
Aging multiple short-duration exercise training single long-duration exercise training heat shock protein
2015/8/28
However, the associated molecular mechanisms mediating
different types of exercise training-induced adaptations are not
yet completely understood. Therefore, the purpose of this study
was to inv...
Effects of a moderate intake of beer on markers of hydration after exercise in the heat: a crossover study
Dehydration Hot conditions Running Alcohol Diuresis Young men
2015/7/30
Exercise in the heat causes important water and electrolytes losses through perspiration. Optimal rehydration is crucial to facilitate the recuperation process after exercise. The aim of our study was...
Effects of Heat Stress on Ocular Blood Flow During Exhaustive Exercise
Hyperthermia exercise healthy subjects retinal circulation choroidal circulation laser-speckle flowgraphy
2015/5/21
The hypothesis that heat stress reduces the ocular blood flow response to exhaustive exercise was tested by measuring ocular blood flow, blood pressure, and end- tidal carbon dioxide partial pressure ...
Exercise Training-Induced Changes in Inflammatory Mediators and Heat Shock Proteins in Young Tennis Players
Hydrogen peroxide cytokines Hsp27 Hsp70 overreaching
2015/5/15
Heat shock proteins (Hsp) represent proteins’ groups, whose protective function, may be induced by heat, reactive oxygen species, cytokines etc. We evaluated blood levels of Hsp27 and Hsp70, and their...
The Reliability of Adolescent Thermoregulatory Responses During a Heat Acclimation Protocol
Reliability heat acclimation aural temperature mean skin temperature
2015/4/24
This study investigated the between trial variation of thermoregulatory measures during a heat acclimation protocol. Eight 14-16 y old boys completed three bouts of 20-min cycling at 45 % peak VO2 in ...
Older Firefighters Are Susceptible to Age-Related Impairments in Heat Dissipation
OCCUPATIONAL HEAT STRESS WHOLE-BODY HEAT LOSS FIREFIGHTING CALORIMETRY BODY HEAT STORAGE
2017/4/19
Purpose: The aging-induced reduction in whole-body heat loss (HL) capacity generates concerns regarding the continued participation of older workers in occupations such as firefighting. We compared HL...
Effects of Palm Vitamin E Supplementation on Exercise-Induced Oxidative Stress and Endurance Performance in the Heat
Oxidative stress endurance heat malondialdehyde palm vitamin E
2015/3/23
This study investigates the effects of tocotrienol-rich palm vitamin E supplementation on exercise-induced lipid peroxidation and endurance performance in the heat. In a double blind, cross-over study...
Sprint-Interval Training Induces Heat Shock Protein 72 in Rat Skeletal Muscles
Hindlimb treadmill running enzyme activity fiber type shift hypertrophy
2015/3/18
Previous studies have demonstrated that endurance exercise training increases the level of heat shock proteins (HSPs) in skeletal muscles. However, little attention has been drawn to the effects of hi...
Effect of 30°C Heat on the Anaerobic Capacity of Heat Acclimatised Athletes
Maximal accumulated oxygen deficit anaerobic metabolism environmental temperature maximal exercise
2015/3/11
The main finding of this study was that for heat acclimatised athletes, there was no significant difference (p=0.58) in anaerobic capacity for temperate (21.8 ± 0.5 °C; 52 ± 5 % relative humidity) com...
Impairments in Local Heat Loss in Type 1 Diabetes during Exercise in the Heat
SWEATING SKIN BLOOD,FLOW CORE,TEMPERATURE THERMOSENSITIVITY CHRONIC,DISEASE
2017/5/25
Studies show that vasomotor and sudomotor activities are compromised in individuals with Type 1 diabetes mellitus (T1DM), which could lead to impaired skin blood flow (SkBF) and sweating during heat s...
Role of Ape1 and Base Excision Repair in the Radiation Response and Heat-radiosensitization of HeLa Cells
radiation hyperthermia DNA repair
2014/12/12
Background: The mechanism by which heat sensitizes mammalian cells to ionizing radiation remains to be elucidated. We determined whether base excision repair (BER) is involved in heat-radiosensitizati...
