At high altitude, even the fittest mountaineer’s ability to move freely can vanish in the thin air. But it’s not the fault of your muscles. In fact, this drop-off in athletic performance in low-oxygen conditions may be mostly in the mind: the brain kicks in to prevent potentially damaging overexertion. The cause of muscle fatigue [...]

By: S Libicz, B Roels, G P Millet Journal: Canadian journal of applied physiology = Revue canadienne de physiologie appliquée While the physiological adaptations following endurance training are relatively well understood, in swimming there is a dearth of knowledge regarding the metabolic responses to interval training (IT). The hypothesis tested predicted that two different endurance [...]
