Heat exercise training may increase exercise performance in athletes. The underlying
mechanisms remain partly unresolved, and it is unknown if female and male athletes may …

Results During the initial 5 wk, SUIT and CHAMBER increased Hb mass (2.6% and 2.4%) to
a greater extent than CON-1 (-0.7%; both P< 0.01). The power output at 4 mmol· L-1 blood …

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 …

New Findings What is the central question of this study? Do haemoglobin mass and red
blood cell volume increase in elite cyclists training in a hot environment compared to a …

Although some studies showed a relationship between skin temperature and physical
fitness, it is unclear if cycling experience could have an influence on thermoregulation. The …

The aim of the present study was to determine the effect of carbohydrate (CHO; sucrose)
ingestion and environmental heat on the development of fatigue and the distribution of …

Human endurance performance can be predicted from maximal oxygen consumption
(V̇o2max), lactate threshold, and exercise efficiency. These physiological parameters …

Purpose: To investigate the effects of short-term, high-intensity interval-training (HIIT) heat
acclimation (HA). Methods: Male cyclists/triathletes were assigned into either an HA (n= 13) …

Background To examine whether short-term, ie, five daily sessions, vigorous dynamic
cycling exercise and heat exposure could achieve heat acclimation in trained athletes and …

Reports of low energy intakes in trained female athletes imply they have an increased
energetic efficiency. To address this question, we determined how energy balance was …
