The many effects of increasing cadence
An advantage of changing running cadence (steps per minute), is that it has a wide-ranging impact on a number of different variables.
From Heiderscheit's 2011 study, we see that increasing cadence by 5% resulted in:
reduced loading of the knee 20%
reduced step length,
foot landed closer to the body,
reduced braking forces,
reduce the vertical excursion of the centre of mass,
reduced peak adduction angle of the hip,
reduced peak flexion angle of the knee during stance phase
An increase in 10% resulted in:
reduced loading of the hip
reduced stance duration
reduced inclination of the foot at initial ground contact
reduced peak vertical ground reaction force
increased rating of perceived exertion
reduced peak flexion angle of the hip
reduced peak hip adduction torque
reduced peak hip internal rotation torque
increased knee flexion angle at initial ground contact
reduced peak knee extension torque
IF we are altering a runner's cadence, we ascribe to the mantra "change the least to affect the most". In other words, if we increase cadence, we want to do so by the smallest amount to achieve the desired result. It would be very rare for us to increase someone's cadence by as much as 10%
