Altitude Training and Endurance and Ultra-Endurance Performance [PDF]

Muscles, Ligaments and Tendons Journal, 2020
Background. Altitude training has been shown to improve endurance and ultra-endurance performance at altitude, whereas the possible benefits from altitude/hypoxic training for competing at sea level have been, and still are, a matter for debate. Reasons for this discrepancy may result from the variety of protocols utilized in terms of altitude, natural

Concurrent brain endurance training improves endurance exercise performance [PDF]

Journal of Science and Medicine in Sport, 2021
Mental fatigue impairs endurance exercise. Brain endurance training (BET) - engaging in cognitively fatiguing tasks during exercise - can develop resilience to mental fatigue and improve physical performance over physical training alone. The mechanism for this effect is unknown.

Hypoxia Improves Endurance Performance by Enhancing Short Chain Fatty Acids Production via Gut Microbiota Remodeling

Frontiers in Microbiology, 2022
Hypoxia environment has been widely used to promote exercise capacity. However, the underlying mechanisms still need to be further elucidated. In this study, mice were exposed to the normoxia environment (21% O2) or hypoxia environment (16.4% O2) for 4 ...

The influence of training status, age, and muscle fiber type on cycling efficiency and endurance performance. [PDF]

, 2013
The purpose of this study was to assess the influence of age, training status, and muscle fiber-type distribution on cycling efficiency. Forty men were recruited into one of four groups: young and old trained cyclists, and young and old untrained ...

Limits in endurance performance of octogenarian athletes [PDF]

Journal of Applied Physiology, 2013
TO THE EDITOR: A recent study of Trappe et al. (3) showed that the aerobic power of octogenarian lifelong endurance athletes was approximately double that of untrained octogenarians (38 vs. 21 ml·kg 1 ·min 1 ). These remarkable aerobic capacities are the highest ever recorded in this age group.

Pre-cooling for endurance exercise performance in the heat: a systematic review [PDF]

, 2012
Background Endurance exercise capacity diminishes under hot environmental conditions. Time to exhaustion can be increased by lowering body temperature prior to exercise (pre-cooling).
