Objective: The present study intends to see the effect of yoga practices on lipid profile, interleukin (IL)-6, tumor necrosis factor (TNF)-α, and high-sensitivity-C-reactive protein (hs-CRP) among apparently healthy adults exposed to occupational hazards.
Materials and methods: In the present study, 48 participants aged 30-58 years (41.5 ± 5.2) who were exposed to occupational hazards were randomized into two groups, that is, experimental and wait-list control. All the participants were assessed for lipid profile, IL-6, TNF-α, and hs-CRP at the baseline and after completion of 3 months of yoga training intervention. The experimental group underwent yoga training intervention for 1 h for 6 days a week for 3 months, whereas control group continued with their daily activities except yoga training. Data analysis was done using statistical software SPSS Version 20.0. Data were analyzed using paired t-tests and independent t-test.
Results: The results of within group comparison revealed highly significant changes in cholesterol (P < 0.001), high-density lipoprotein (P < 0.001), low-density lipoprotein (LDL)(P < 0.01), hs-CRP (P < 0.01), IL-6 (P < 0.001), and TNF-α (P < 0.001) in experimental group. Comparison between experimental and control group revealed significant changes in cholesterol (P < 0.01), LDL (P < 0.05), IL-6 (P < 0.01), TNF-α (P < 0.01), and hs-CRP (P < 0.01).
Conclusion: A yoga-based lifestyle intervention seems to be a highly promising alternative therapy which favorably alters inflammatory markers and metabolic risk factors.
