Coca chewing for exercise : hormonal and metabolic responses of nonhabitual chewers
(Journal of Applied Physiology, 1996)
Abstract.
To determine the effects of acute coca use on the hormonal and metabolic responses to exercise, 12 healthy nonhabitual coca users were submitted twice to steady-state exercise (∼75% maximal O2 uptake). On one ...
Lactate and epinephrine during exercise in altitude natives
(American Physiological Society, 1996)
Abstract.
We tested the hypothesis that the reported low blood lactate accumulation ([La]) during exercise in altitude-native humans is refractory to hypoxianormoxia transitions by investigating whether acute changes in ...
Maximal exercise performance in chronic hypoxia and acute normoxia in high-altitude natives
(J. Appl. Physiol., 1995)
Maximal O₂ uptake (VO₂max) was determined on a bicycle ergometer in chronic hipoxia (CH) and during acute exposure to normoxia (AN) in 50 healthy Young men who were born and had lived at 3,600 m altitude (La Paz, Bolivia). ...
Differential effects of ventilatory stimulation by sex hormones and almitrine on hypoxic erythrocytosis
(Pflugers Arch-Eur J Physiol, 1997)
Abstract.
In the absence of pulmonary disease, hypoventilation is considered to be the primary cause of
Chronic Mountain Sickness, and there is some reason to
believe that chronic administration of respiratory analeptics ...
Body fluid homeostasis and cardiovascular adjustments during submaximal exercise : inlfuence of chewing coca leaves
(Eur J Appl Physiol, 1997)
Abstract.
The present study was undertaken to determine the haematological and cardiovascular status, at rest and during prolonged (1 h) submaximal exercise (approximately 70% of peak oxygen uptake in a group (n = 12) of ...
Effect of developmental and ancestral high-altitude exposure on VO2peak of andean and european/north american natives
(American Journal of Physical Anthropology, 1999)
ABSTRACT.
Peak oxygen consumption (V02peak) was measured in 150 adult males (18-35 years old) in Bolivia, using a complete migrant study design to partition developmental from ancestral (genetic) effects of high altitude ...
Effects of coca chewing on metabolic and hormonal changes during graded incremental exercise to maximum
(J. Appl. Physiol., 1996)
Abstract.
We examined the effects of 1 h of coca chewing on metabolic and hormonal responses during incremental exercise to exhaustion in traditional coca chewers (C; n = 8), and the results were compared with a group of ...
Exercise training in chronic hypoxia has no effect on ventilatory muscle function in humans
(Respiration Physiology, 1998)
Abstract
At the highest altitude, aerobic work is limited by environmental oxygen availability. We therefore reasoned that the hyperpnea associated with endurance training at altitude should provide a strong stimulus for ...
