Objective: Sedentary lifestyle has emanated as a new attention for research on exercise and health. The objective of this study was to find the correlation between prolonged sitting (minimum 6–8 h) and tightness of hamstrings in students. Materials and Methods: In a cross-sectional study, 200 students were taken. Probability sampling was used on random basis to assess the flexibility of hamstring muscles using the straight leg raising (SLR) and active knee extension test. A manual goniometer was used for range measurement. All information was taken on predesigned pro forma. Result: The mean age of 200 students was 20.3 ± 1.63 years. The mean value of SLR was found to be 60.97 ± 10.21, and mean value of popliteal angle was 47.65 ± 8.06. Most of the students, 164 (82%), had tightness according to SLR test. There was a statistically significant difference between the popliteal angle and chair sitting hours (P = 0.010), and an inverse correlation was found between SLR angle and chair sitting hours (r = −0.56, P = 0.000). Conclusion: Tightness of hamstrings is observed in a majority of the students. Long-duration sitting can be a contributory factor in hamstring tightness.
