Podcast cover

The Human Upgrade: Biohacking for Longevity & Performance

In this episode of The Human Upgrade, Dave Asprey interviews Sten Stray, a researcher in metabolic physiology, about blood flow restriction (BFR) training and intermittent hypoxia. They discuss the benefits of altitude acclimation, the physiological responses to hypoxia and hyperoxia, and how intermittent hypoxia can improve glucose clearance and insulin sensitivity. The conversation covers the practical applications of BFR, including its use in building muscle with light weights, enhancing recovery, and improving blood sugar levels. They also explore the systemic benefits of BFR, its impact on libido, and the mechanisms by which it increases nitric oxide levels. Additionally, they touch on stacking BFR with other modalities like whole-body vibration and electrical muscle stimulation, as well as the potential benefits of transient testosterone spikes and the use of cognitive enhancers.
