Progress in technology leads to a major life-style changes in terms of decrease in physical activity and increase in prevalence of sedentary lifestyle, which affects the functions of all systems in the human body. Considering the poor evidence of the relationship between sedentary lifestyle and respiratory health, the aim of this study was to determine whether there is a correlation between the lifestyle of the 1st year physiotherapy student sand the function of the respiratory system. A questionnaire for assessment of life habits was answered by 36 students aged 19-21 (12 men and 24 women). Forced vital capacity was determined by spirometry. The results show that the difference between men and women in involvement in sedentary activities is not statistically significant, but the malesin the sample are spending significantly more time in physical activity compared to females. The vital capacity values are significantly higher for males than for females. In females, the mean value z-score is negative, indicating a decreased vital capacity relative to normal values for gender, age and height of subjects. A positive correlation of forced vital capacity with running and exercising in the gym was found, as well as negative correlation between forced vital capacity with time spent sitting while driving by means of transport. Based on the results, it could be concluded that the subjects are mainly sedentary, and rarely engaged in sports. Physically active subjects showed better vital capacity results. Forced vital capacityin first-years physiotherapy students is positively correlated to physical activity, and negatively correlated to sedentary activities and smoking.
