The impact of hypoxia on growth hormone levels in response to a maximal strength training session

Performing resistance exercise in a hypoxic environment has been shown to improve gains in muscle strength and hypertrophy, even at low intensities. These adaptations are thought to occur via increases in the accumulation of metabolites and secretion of anabolic hormones, such as growth hormone (GH). The majority of research conducted has assessed these adaptations with the use of low-intensity, high-volume (hypertrophy-type) protocols. However, there is little research investigating the effects of metabolic and hormonal responses to a typical strength training (high-intensity, low-volume) session. Therefore, the purpose of this investigation was to examine whether hypoxia can influence the metabolic stress and GH response during a maximal strength training session.
