Heat Strain Is Exacerbated on the Second of Consecutive Days of Fire Suppression
HEAT STRAIN HEAT STRESS FIREFIGHTERS RECOVERY
2018/4/24
Purpose We tested the hypothesis that physiological and perceptual heat strain is exacerbated on the second of back-to-back days of fire suppression work despite evidence of full recovery.
Methods Tw...
Temperate Performance Benefits after Heat, but Not Combined Heat and Hypoxic Training
HEAT ACCLIMATION HYPOXIA PLASMA VOLUME ENDURANCE HEMOGLOBIN MASS
2018/4/24
Purpose Independent heat and hypoxic exposure can enhance temperate endurance performance in trained athletes, although their combined effects remain unknown. This study examined whether the addition ...
Tyrosine Ingestion and Its Effects on Cognitive and Physical Performance in the Heat
HEAT STRESS CENTRAL FATIGUE AMINO ACIDS
2017/4/13
Purpose: Ingestion of tyrosine (TYR), a catecholamine precursor, has previously improved aspects of cognitive function and mood during acute stress, although there is limited research exploring the op...
Brain serotonin and dopamine modulators, perceptual responses and endurance performance during exercise in the heat following creatine supplementation
Brain serotonin dopamine modulators
2015/7/14
The present experiment examined the responses of peripheral modulators and
indices of brain serotonin (5-HT) and dopamine (DA) function and their association with
perception of effort during prolong...
Differential Response of Heat Shock Proteins to Uphill and Downhill Exercise in Heart, Skeletal Muscle, Lung and Kidney Tissues
HSP70 stress concentric exercise eccentric exercise metabolic stress
2015/5/18
Running on a horizontal plane is known to increase the concentration of the stress biomarker heat-shock protein (HSP), but no comparison of the expression of HSP70 has yet been established between the...
Field-Based Pre-Cooling for On-Court Tennis Conditioning Training in the Heat
Cooling heat training GPS racquet sports
2015/5/7
The present study investigated the effects of pre-cooling for on- court, tennis-specific conditioning training in the heat. Eight highly-trained tennis players performed two on-court conditioning sess...

2017/4/19
Purpose: The objective of this study was to examine the effect of ingested water temperature on heat balance during exercise as assessed by direct calorimetry.
Methods: Ten healthy males (25 ± 4 yr) ...
On the Maintenance of Human Heat Balance during Cold and Warm Fluid Ingestion
Human Heat Balance Warm Fluid Ingestion
2017/4/19
The influence of ingested fluid temperature on thermoregulatory responses during exercise has attracted considerable attention during the past decade. To date, however, it has remained unclear whether...

EXERCISE HOT AMBIENT CONDITIONS TEMPERATURE ACCLIMATIZATION HYPERTHERMIA FATIGUE
2017/4/14
Purpose: This study aimed to determine the effects of heat acclimatization on performance and pacing during outdoor cycling time trials (TT, 43.4 km) in the heat.
Methods: Nine cyclists performed thr...
Whole-Body Heat Exchange during Heat Acclimation and Its Decay
HEAT ACCLIMATIZATION DIRECT CALORIMETRY EVAPORATIVE HEAT LOSS BODY HEAT STORAGE CORE TEMPERATURE HEAT BALANCE
2017/4/14
Purpose: The purpose of this study was to quantify how much whole-body heat loss increases during heat acclimation and the decay in these improvements after heat acclimation.
Methods: Ten males under...
Effectiveness of Cold Water Immersion in the Treatment of Exertional Heat Stroke at the Falmouth Road Race
HYPERTHERMIA EXERTIONAL HEAT STROKE COLD WATER IMMERSION COOLING RATE
2017/4/14
Purpose: This study aimed to investigate the effectiveness (speed of cooling and survival rates) of cold water immersion (CWI) in the treatment of patients with exertional heat stroke (EHS). Secondly,...
Time Trial Performance and Pacing in Heat is Determined by Rate of Heat Gain
Time Trial Performance and Pacing Rate of Heat Gain
2017/4/14
The very elegant study by Racinais et al. (6) shows for the first time that at least one outcome of heat acclimatization is altered pacing strategy. A key finding from their Figure 1 was the attenuate...
