Higher Workload, not Hypoxia, Enhances Acute Mitochondrial Respiratory Responses to High-Intensity Interval Exercise in Men with Overweight or Obesity.
PURPOSE This study investigated whether skeletal muscle mitochondrial responses to a single session of high-intensity interval exercise (HIIE) in men with overweight or obesity were influenced by hypoxia or absolute power output. The HIIE performed in hypoxia (HY; inspired oxygen fraction [FiO2] = 14.0%) was matched wi...
