This study deals with the effects of ten-day curriculum of physical activities in nature Course on functional abilities of male students. The research was carried out on a sample of 22-25 year old students who attended the Activities in Nature Course at the Faculty of Sport and Physical Education in Niš. Five variables which encompassed the functional abilities were measured ( pulse under load, fitness index, maximum oxygen consumption, systolic pressure of arterial blood, diastolic pressure of arterial blood). Statistica 6.0., a statistical package for data processing, was applied in these analyses. Basic parameters of descriptive statistics were calculated for all the results (arithmetical mean, minimum value, maximum value, range, standard deviation). Discriminative analysis was applied in defining the differences between the initial and final measurements. Research results have shown that statistically vital changes occurred (p= .041). While the greatest changes occurred in the variables of systolic pressure of arterial blood (TASIA) and pulse under load (PULSE), the smaller ones occurred in variables of maximum oxygen consumption (VO2 max), fitness index (FITIND) and diastolic pressure of arterial blood (TADIA). .
