摘要：AbstractThis paper is part of an ampler approach that aims at emphasizing the efficiency of outdoor activities for increasing the quality of life in persons of different age categories. Within our study, the opportunity of these activities introduced into the adult persons’ program of physical exercises is assessed through the functional alterations registered at the individual's body level, under the conditions of his participation in altitude trekking activities. At the same time, we think that an extension of the outdoor-type activities to the persons of any age will decisively improve the individual's degree of awareness about the importance of conserving the natural environment and, consequently, his involvement on this direction.
