Article Synopsis
- Short-term heat acclimation (HA) for trained athletes boosts sweating adaptations and thermal resilience, but prolonged HA is better for benefits in cooler conditions and red blood cell production.
- In a study with 20 elite cyclists, those undergoing 5 weeks of HA saw significant improvements in exhaustion time, sweat rates, and reduced sodium concentration after intense heat exposure.
- However, these benefits diminished quickly after a 2-week break from HA, indicating that while short-term acclimation is effective, the endurance gains may not last long without continued practice.
Fatigue resistance is vital for success in elite road cycling, as repeated, intense efforts challenge the athletes' ability to sustain peak performance throughout prolonged races. The present study combined recurrent performance testing and physiological measures during 6 h simulated racing with laboratory testing to investigate factors influencing fatigue resistance. Twelve male national elite cyclists (25 ± 3 years; 76 ± 6 kg and VO of 5.
