Hypothesis

Antirust agents can modify cardio-lung responses to acute exposure to altitude

Acute exposure to altitude involves the possibility of oxidative stress.

Design of the research
	Simulated exposure to altitude (4500m, 440mmHg) Voluntarios (29h y 18m), fueron expuestos en reposo en cámara hipobárica, durante 20 minutos, antes y después de 2 meses de ingerir diariamente una mezcla de antioxidantes (vitE 400UI+vitC1000mg).
	Exposure to real altitude (3700m, 495mmHg) 14 students were evaluated in a double blind research (antirust and placebo), resting and then maximum exercise, at sea level and in altitude and after two months of daily having a mixture of antirust agents (vit E 400UI + vit C1000mg) or placebo.
