Randomized controlled trial investigating the role of yoga at workplace in improving fatigue, burnout, pain, strength, and quality of life among blue-collar workers

BACKGROUND: Due to the physical demands of work, blue-collar workers (BCW) frequently experience fatigue, musculoskeletal pain, and burnout. The purpose of this study was to determine the feasibility and utility of introducing yoga-based loosening exercises (YLE) at the workplace for improving fatigue, musculoskeletal pain, and burnout among BCW. MATERIALS AND METHODS: One hundred and twenty-eight BCW were randomized into a yoga group that received 40 minutes of supervised YLE daily, 5 days a week, for 1 month, followed by 1 month of unsupervised practice at home or a waitlisted control group. The Chalder Fatigue Scale (CFS), Visual Analog Scale for pain, Oldenburg Burnout Inventory (OLBI), sit-and-reach test (SRT), handgrip strength dynamometer, and the Short Form-8 (SF-8) questionnaire were measured at baseline, at the end of the first month, and at follow-up after the first month. RESULTS: All the participants adhered well to the YLE (≈86% at the workplace, ≈70% at home). Compared to the controls, the yoga group reported significant reductions in fatigue, pain, and burnout and significant improvements in flexibility, strength, and quality of life (P < 0.001) at all the time points. CONCLUSION: Our findings demonstrate that workplace yoga programs for BCW are feasible and can considerably reduce fatigue, pain, and burnout and improve their quality of life.
