Background: flexibility is an important physical characteristic in athletes in terms of performance and injury prevention. Active Range Of Motion (AROM) was assessed in elite Greek track and field athletes. 

Methods: prospective cohort study was carried out. In the period 2000-2010, the AROM was measured bilaterally with the Active Knee Extension (AKE) test during an in-season period with a goniometer in 127 athletes. 

Results: male runners and jumpers had a higher mean AROM than throwers, but this result was not statistically significant. Female jumpers had a higher mean AROM than both runners and throwers, but the difference was also not statistically significant. Conclusion: in athletes, mean posterior thigh muscle flexibility is likely to be between 72.3o and 73.9o. Posterior thigh muscle flexibility is associated with performance, the higher the AROM, the better performance is achieved athletes have generally high AROM, and this may be a result of their increased muscle flexibility. The normative values of posterior thigh flexibility may assist in better monitoring rehabilitation of the posterior thigh muscle injuries and be useful in pre-season screening of athletes’ flexibility.
