Study aim: To assess the relations between anthropometric and cardio-respiratory indices, and aerobic capacity of students, differing in the level of physical activity, under resting and exercise conditions.Material and methods: A group of 87 male and 75 female students volunteered to participate in the study.

Anthropometric (body height and mass, body fat content, BMI and WHR) and physiological indices (heart rate, blood pressure, O2max, CO2 and minute ventilation) were recorded.
