The current study looks into comparison made in cardiovascular functional abilities of students before and after eight weeks staircase climbing. 60 medical students of age group 18–25 years of tertiary health centre of Municipal Corporation of Greater Mumbai were included in the study. Regular stair climbing exercise induces significant adaptations both at rest and during exercise in a variety of factor like heart rate, blood pressure, physical fitness index and maximal aerobic power. These changes suggest significant increase in cardiovascular fitness after training of stair climbing for 8 weeks. As fitness levels improve, the body functions more efficiently and the heart can better withstand the strains of everyday stress.
