Track cycling performance is dependent upon five major variables.
1. Training to maximize power, either sustained power or sprinting power.
2. The need to ride at high cadences.
3. Maximizing endurance (minimizing fatigue)
2. Optimizing technique.
3. Optimizing aerodynamics.
Regardless of how and how much you train PowerCranks can help you to get more out of that time spent training. Track racing usually requires a trade off. A small gear optimizes acceleration but limits speed because high speed requires high cadences with low gearing. Cadence is limited, usually, by less than optimal coordination. PowerCranks train optimal, efficient, coordination to allow the rider to reach higher cadences and improve efficiency reducing fatigue. One track racer reported to us that he was able to improve his maximum unloaded cadence from 180 to 240 and his max sustainable cadence to over 200 after 6 years of PowerCranks training.
PowerCranks also allow the rider to easily experiment with optimum crank length as higher cadences are easier with shorter crank lengths. PowerCranks also train more muscles which allow riders to generate more power at low cadences and shorter crank lengths for better acceleration at low speeds.
That having been said, lets assume the most important part of the race is the last 10-20%, where the effects of fatigue are coming into play and where, if sprinting, power needs to be maximized. Three studies highlight how training with PowerCranks can really help during this period. The first by Hug shows the importance of the backstroke, relative to the downstroke, when trying to maximize sprinting power. And, the studies by Dorel and Sanderson show how the backstroke muscles are the ones that fatigue first when approaching exhaustion. If one wants to maximize performance for sprinting and at the very end of the race one needs to ensure that the backstroke muscles are trained equivalently to the pushing muscles. This is exactly what training with PowerCranks does for the cyclist.
PowerCranks can help the track rider develop all of these skills. Used by some of the best track cyclists in the world including Olympic medalists Miribella, Llaneras, and Roulston.
