About these units
Yard/Second (yd/s)
A yard per second is a moderately fast speed, equal to 3 ft/s or 0.9144 m/s, used in some athletic contexts—particularly American football or sprinting analysis. It provides an intuitive measure for sports where yard-based distances dominate. Because the unit aligns with common field dimensions, it simplifies performance evaluation in training and gameplay. The yard per second reflects the enduring influence of imperial measurements in American athletics.
Running Speed (run)
Human running speeds range widely: Average jogging (2.5–3.3 m/s or 9–12 km/h), Sprint speeds (8–12 m/s or 29–43 km/h). Elite sprinters can exceed 12 m/s, with Usain Bolt's peak reaching approximately 12.4 m/s. Running is biomechanically complex, involving elastic energy return, stride mechanics, ground-reaction forces, and cardiovascular performance. Sports science uses running speed to evaluate training outcomes, optimize gait, prevent injuries, and enhance athletic performance. Running speed provides a window into human physical capability and evolutionary adaptations.
