    • Body fluid homeostasis and cardiovascular adjustments during submaximal exercise : inlfuence of chewing coca leaves 

      Spielvogel, Hilde; Rodríguez, Armando; Sempore, Brigitte; Cáceres, Esperanza; Cottet-Emard, Jean-Marie; Guillon, Laurent; Favier, Roland (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 ...

    • Coca chewing for exercise : hormonal and metabolic responses of nonhabitual chewers 

      Favier, Roland; Cáceres, Esperanza; Guillon, Laurent; Sempore, Brigitte; Sauvain, Michel; Koubi, Harry; Spielvogel, Hilde (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 ...

    • Dopaminergic metabolism in carotid bodies and high altitude acclimatization in female rats 

      Joseph, Vincent; Soliz, Jorge; Soria, Rudy; Pequignot, Jacqueline; Favier, Roland; Spielvogel, Hilde; Pequignot, Jean Marc (Am J Physiol Relulatory, 2002-04)
      We tested the hypothesis that ovarian steroids stimulate breathing through a dopaminergic mechanism in the carotid bodies (CB). In ovariectomized female rats raised at sea level, domperidone, a peripheral D2 receptor ...

    • Effects of coca chewing on hormonal and metabolic responses during prolonged sbmaximal exercise 

      Favier, Roland; Cáceres, Esperanza; Koubi, Harry; Sempore, Brigitte; Sauvain, Michel; Spielvogel, Hilde (J Appl Physiol, 1996)
      Abstract The effects of coca chewing on prolonged submaximal exercise responses were investigated in chronic coca chewers and compared with a group of nonchewers. At rest, coca chewing during a 1-h period was followed by ...

    • Effects of coca chewing on metabolic and hormonal changes during graded incremental exercise to maximum 

      Spielvogel, Hilde; Cáceres, Esperanza; Koubi, Harry; Sempore, Brigitte; Sauvain, Michel; Favier, Roland (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 

      Thomas, Rickey G; LaStayo, Paul C; Hoppeler, Hans; Favier, Roland; Ferretti, Guido; Kayser, Bengt; Desplanches, Dominique; Spielvogel, Hilde; Lindstedt, Stan L (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 ...

    • Influence of coca chewing on hematological and cardiorespiratory responses to submaximal exercise 

      Spielvogel, Hilde; Rodríguez, Armando; Sempore, Brigitte; Cáceres, Esperanza; Cottet-Emard, Jean-Marie; Guillon, Laurent; Favier, Roland ([s.n.], 1996)
      Summary. The cardiovascular effects of cocaine are relatively well known but little information is available concerning those of coca chewing. The present study was undertaken to determine the hematological and cardiovascular ...

    • Lactate and epinephrine during exercise in altitude natives 

      Kayser, Bengt; Favier, Roland; Ferretti, Guido; Desplanches, Dominique; Spielvogel, Hilde; Koubi, Harry; Sempore, Brigitte; Hoppeler, Hans (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 

      Favier, Roland; Spielvogel, Hilde; Desplanches, Dominique; Ferretti, Guido; Kayser, Bengt; Hoppeler, Hans (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). ...
