← Human Body & HealthWhy does increased cadence reduce impact loading in human running biomechanics?
A)Reduced stride decreases overall force
B)Ground contact time increases impulse
C)Muscles eccentrically resist slower impacts
D)Vertical displacement lowers braking force✓
💡 Explanation
Increased cadence reduces impact loading because it shortens stride length, thereby decreasing vertical displacement during ground contact. This reduction in vertical displacement lowers the magnitude of the required braking force; therefore, impact forces decrease, rather than increasing force or relying on eccentric muscle action.
