Cytokine response at high altitude: Effects of exercise and antioxidants at 4300 m

Article Abstract:

A study tested the hypothesis that antioxidant supplementation would attenuate plasma cytokine (IL-6, tumor necrosis factor and C-reactive protein (CRP) concentrations at rest and in response to exercise at 4300-m elevation. Plasma IL-6 and CRP concentrations were elevated following exercise at high altitude on day 1, and antioxidant supplementation did not attenuate the rise in plasma IL-6 and CRP concentrations associated with hypoxia, exercise and caloric deficit.

Changes in ventilatory threshold at high altitude: Effect of antioxidants

Article Abstract:

A study was conducted to investigate the effects of prolonged hypoxia and antioxidant supplementation on ventilatory threshold (VT) during high-altitude (HA) exposure. VT decreases upon acute HA exposure but improves with acclimatization and Prior AO supplementation improves VT upon acute but not chronic altitude exposure.
