摘要:Background and study aim. Extreme altitude climbing effects have been described in several studies. Usually these studies are carried out on expeditions but not longitudinally. The aim of this study is to describe physiological and kinanthropometrical changes over the time in a top-level climber. Material and Methods. This is a single-subject study on an individual career part (from ages 30 to 41). Some physiological and kinanthropometrical parameters were analysed in 3 different season parts at sea level; before (PRE), after (POST) and off climbing expeditions (OFF). All expeditions were > 7000 m. Results. No changes were found in physiological parameters during the period of study regarding to season part. Kinanthropometry in contrast, presented significant changes (P<0.01) in two skinfolds (PRE/OFF Vs. POST), whereas ∑ of SF showed differences between (PRE vs. OFF). Results also indicate some significant correlations (P<0.05) between both kinanthropometrical and physiological variables and the participant aging process. Conclusion. The high fitness level of the participant combined with his gift for acclimatization and a broad climbing career, maintain physiological and kinanthropometrical stability during the analysed period even after repeated exposure to extreme altitudes. However, aging process appears to be involved in maximal exercise cardiovascular capacity decline. Surprisingly, kinanthropometrical variables such as weight, BMI and fat percentage showed lower values through the time attributable probably to a high physical activity
