Abstract

Background: Walking uphill and downhill on motor-driven treadmills has been included in different exercise programs for athletes or for rehabilitation purposes. The body’s response to uphill, level, and downhill walking is different, and those responses vary from one group of individuals to another. Abundant work has been done by considering the treadmill, but very few studies have been done by changing the gradient levels in these treadmills.

Aim and Objective: The aim of the study was to evaluate pulmonary responses, Stride Length, and perceived exertion during Uphill, Level, and Downhill walking in various Body weights among young adults in undergraduate students. The objectives were – (i) To evaluate pulmonary responses, stride length, and perceived exertion while Uphill walking; (ii) To evaluate pulmonary responses, stride length, and perceived exertion while level walking; (iii) To evaluate pulmonary responses, stride length, and perceived exertion while Downhill walking; (iv) To compare the pulmonary responses, stride length, and level of exertion experienced when walking uphill, level, and downhill.

Materials and Methods: After receiving approval for the study from the institutional human ethics committee, a sample of 60 people were enrolled who were subsequently divided into three groups based on their body mass index (BMI). Each group has 20 participants: the overweight group has a BMI of 25–29 kg/m2, the normal group has a BMI of 18.5–24.9 kg/m2, and the underweight group has a BMI of
