Study population: study design was Analytical (Correlational) study design. During the first visit, First of all, 'true' VO2max of all subjects was calculated using non-exercise regression equation and one mile walk test.

On the 2nd visit, the participants performed Modified Bruce Submaximal Exercise test depending upon their fitness level and Mankato Submaximal Exercise test in counter balanced order with 30 minutes rest in between.

Brief summary: * To measure the maximal oxygen uptake (VO2max) using Mankato Submaximal Exercise test.
* To correlate 'true' VO2max with Modified Bruce protocol and Mankato Submaximal Exercise Test.

Detailed description: First of all, 'true' VO2max of all subjects was calculated using non-exercise regression equation and one mile walk test. Variables used for the VO2max regression equation included BMI, age (years), gender (Male=1, Female=0) and physical activity rating scale. On the same visit, the subjects also performed one mile walk test. After the completion of test, pulse rate of subjects was calculated in beats per minute. The VO2max after the test was measured using the VO2max aerobic capacity calculator. Variables required were age, gender, weight, total time taken to complete test and pulse rate at test completion.

'True' VO2max accepted was the highest value obtained from non-exercise regression equation and one mile walk test On the 2nd visit, the participants performed Modified Bruce Submaximal Exercise test depending upon their fitness level and Mankato Submaximal Exercise test in counter balanced order with 30 minutes rest in between
