Key result
Maximum effort training in hypoxia increases fatigue, mental confusion, and blood lactate vs sea level.
Why the study?
Risks associated with exercise at high altitude are a major concern given the influence of hypoxia and physical exercise stressors on psychobiological and physiological responses.
Does maximum effort training in hypoxia alter mood profile and physiological responses compared to sea level in volunteers?

Does maximum effort training in hypoxia alter mood profile and physiological responses compared to sea level in volunteers?
Maximum effort exercise in a hypoxic environment significantly deteriorates mood and physiological responses compared to sea level.
Giampá et al. (2018) conducted a cross-sectional in Healthy volunteers undergoing maximum effort training. Maximum effort training in hypoxia (simulated altitude of 4500 meters) vs. Maximum effort training at sea level was evaluated on Mood state (fatigue, mental confusion, vigor) and physiological variables (oxygen-hemoglobin saturation, blood lactate). Maximum effort training in a hypoxic environment increased fatigue (p=0.02), mental confusion (p=0.04), and blood lactate (p=0.006) compared to sea level conditions.
