Severely overweight and obese people are more prone for risk of illness and reduced life expectancy. The Body Mass Index has direct impact upon the resistance in airways and pulmonary mechanics. The higher the BMI the lower will be the thoracic lung volumes. So, have done this study to observe the effect of walking on finger oxygen saturation. In this study we include the subjects and give the rest for 15 minutes prior to testing. During that time, demographics and weight and BMI are calculating. The arterial oxygen saturation is measured from the fingertip. Subjects then walked on the treadmill and saturation and heart rate are measure. The walking was done on a treadmill and the treadmill was adjusted to 4.8 kmph at an angle of 3 degrees. The spo2 was calculated after the 5 minutes of the walking. If saturation dropped below 60% or heart rate above 140 beats per minute, the walking are terminate. The readings after the 5 minutes of the test is taken and noted. The BMI affects the oxygen saturation at rest and during the mild walking. The number of population included in the study was eighty one. All the participants was examined and correlated the BMI, atrial oxygen and body fat and the arterial po2 after the rest. All the subjects did a 5 minutes of walking on a treadmill with a speed of 3 miles per hour at an incline angle of 3 degrees. Every participants included were free from all types of cardiovascular diseases and pulmonary diseases and also all the participants had an normal blood pressure. The study showed that there is some sort of negative relationship in fingertip oxygen saturation in the participants having the BMI above 25. The conclusion of the study was that the excess body fat can impair the ability to breathe.
