ABSTRACT Introduction: Oxygen uptake peak (VO2 peak) or VO2 max indicates the functional capacity of cardiorespiratory function and is often considered as the benchmark indicator of cardiorespiratory fitness (McArdle et al., 1996). In addition to evaluating functional capacity in healthy and diseased individuals, VO2 peak is used to prescribe endurance exercise and monitor physical training adaptations (Shephard, 1984). No literature was found that compare VO2peak in treadmill versus level ground walking. Therefore the purpose of this atudy was To compare VO2maxon treadmill versus level ground walking in healthy individuals. Methodology: Thirty healthy subjects (20 females, 10 males) enrolled in the study. All subjects were randomly distributed in two groups, treadmill group and level ground walking group. Rock port 1 mile track walk test was used to measure VO2 peak. Both the group were asked to walk for 1 mine on treadmill and on level ground respectively. Than data was collected and VO2peak was measured using regression equation VO2max (mlmin-1kg-1)=(132.85)-(0.077* Body weight)-(0.39*Age)+(6.32*Gender)-(3.26*Elapsed time)-(0.16*HR) (Foster & Maud) Result : The results obtained from Unpaired t test were found to be significant. The above study suggests that VO2peak was higher on level ground walking than on treadmill walking. Discussion: In present study Elapsed time was taken for walking on treadmill was more than on level ground walking. And in Regression equation, Elapsed time is inversely proportional to the VO2 peak value. This can explain increase value of VO2 peak in level ground walking. This is supported by the Mayer at al ,2003 in his study. Conclusion: . In conclusion, VO2peak were statistically significant (p >0.05) when treadmill was compared to level ground walking during peak exercise in healthy youth. The results of this case study show that a level ground exercise program can be safely recommended to an individual beginning an exercise prescription, as it will elicit similar or greater physiological benefits to that of a land-based exercise program.
