| Abstract | Purpose:The purpose of this study was to determine the difference of H:Q ratio and peak torque between recreational runners with lower and higher mileage per week.Methods:Twenty-three healthy recreational runners (Male = 12 and female = 11) of physical therapy center running project age between 26 –52 years (mean ± SD: 40.52 ± 8.38) were allocated to the “higher-mileage” group (> 32 km/week; n = 14) and to the “lower-mileage” group (< 25 km/week; n = 9) in 2018-2019. The performance of the knee muscles was tested by isokinetic dynamometer at angular velocity of 60, 120 and 180 degrees per second (º/s). The results of H:Q ratio and peak torque were analyzed with Independent-T Test and Mann-Whitney U to compare the data between the groups. Results:Runner group with higher-mileage demonstrated a higher H:Q ratio than the group with lower-mileage at all angular velocities. At an angular velocity of 180º/s, the group with higher-mileage showed significantly higher H:Q ratio than the group with lower-mileage (p <0.05). No significant difference of peak torque was observed between both groups.Conclusion:Running with a cumulative distance of > 32 km/week seems to approximate the normative quadriceps and hamstring muscle balance (The normal H:Q ratio is considered to be 60%). The H:Q ratio is likely to be normal in runner group with higher-mileage compared with the lower mileage group.When health professionals determine for runningdistance accumulation, the current findings could be used as a guidance in running rehabilitation |
