Background: In this article we report our findings on correlation between body mass index (BMI) and lactate threshold (LT) during an aerobic exercise. Total 30 male subjects of age in the range of 20- 40 years, classified into three different categories, normal, overweight and obese, performed a treadmill exercise as per Bruce Protocol and their respiratory parameters were recorded. We analyzed our experimental data for each of the three groups individually as well as altogether. Statistical data analysis revealed that LT decreases with increase in BMI. This trend was found to be consistent within and across the groups.

Materials and Method: All participants in this study were first medically examined to confirm that they did not have any cardiorespiratory complications; and their BMI was calculated. Based on their BMI, they were classified into three-normal, overweight obese groups and subjected to a treadmill exercise with Bruce Protocol.

Result: Lactate threshold decreases with increase in BMI within and across the groups

Conclusion: This study establishes a correlation between lactate threshold and BMI of individuals that suggests that with increased BMI, lactate threshold decreases resulting into a decrease in respiratory fitness level.
