Association between hamstring and lower back flexibility and sprint speed in cricketers

Aim: The aim of this study was to examine the relationship between hamstring and lower back flexibility and sprint speed performance. Methodology: Total 168 cricketers (both male and female) included of aged 19-25 years. The cricketers were assessed for flexibility using the Active Knee Extension Test (AKET) for hamstrings and the Sit and Reach Test (SRT) for lower back flexibility. Sprint speed was measured using a 30-meter sprint test. Data were analyzed using SPSS software, and Pearson’s correlation coefficient was applied to assess the relationship between flexibility and sprint speed. Results: The results showed that females demonstrated greater hamstring and lower back flexibility than males, with no significant differences between dominant and non-dominant limbs for either gender. Conclusion: There was a weak negative correlation between hamstring flexibility and sprint speed in males, while no such correlation was observed in females. Additionally, lower back flexibility did not significantly correlate with sprint performance in either gender. The study also found that lower back pain (LBP) was prevalent among fast bowlers, with reduced quadriceps and hamstring strength linked to an increased risk of LBP. These findings suggest that maintaining an optimal balance between flexibility and strength is crucial for improving sprint performance and reducing injury risk in cricketers.
