Sportspeople must sometimes change residence during short or medium time periods for sports/training meetings. These changes may modify their normal habits of life, affecting correct nutritional supply. Frequent meetings are necessary for Andalusian Alpine skiers due to the few months when snow is available (maximum 4-5 months). A study was made of a group (n=6) of young skiers federated in Andalusia who usually train at ≥ 2300 m, observing possible nutritional modifications produced during a three-month training at a ski resort in southern Chile (<1000 m). Anthropometric and nutritional data during this period were recorded in a diary designed for the study, analyzing body composition variables and energy and macronutrient intakes (with SPSS 15.0 statistical software). Just before the training meeting, the group had mean BMI of 18.35 Kg/m2 and intake of 3153 Kcal/day (416.6 g carbohydrates, 122.3 g lipids, 96.4 g proteins). Mean values at the end of the meeting were BMI of 18.68 Kg/m2 and intake of 2732.66 Kcal/day (383.5 g carbohydrates, 96.1 g lipids, 83.5 g proteins), observing a reduction in energy and nutrients during this three-month training period below 1000 m.
