Why does power output decrease at high pedaling rates during sprint cycling?

Article Abstract:

An analysis of electromyographical (EMG) activity is employed to examine the decrease in the power output beyond the optimal pedaling rate (PRopt) in a person during sprint cycling. The analysis reveals that sprint cycling leads to alterations in the muscle coordination, which leads to an increase in the response of the crank angles corresponding to the muscle force that finally leads to the decrease in the power output during sprint cycling.

Which factors determine the optimal pedaling rate in sprint cycling?

Article Abstract:

This study uses a two-dimensional skeletal model to examine the musculoskeletal dynamics associated with the optimal pedaling rate and power output level in sprint cycling. Findings indicate that optimal pedaling rate in cycling is associated with activation dynamics and the power-velocity interaction in leg muscles.

Leg power and hopping stiffness: relationship with sprint running performance

Article Abstract:

This study uses an ergometric treadmill and a contact force platform to investigate the effects of leg power and stiffness on sprint performance. Results indicate that leg power helps runners accelerate and maintain speed while leg stiffness produces an effective rebound that also contributes to speed maintenance.
