What truly distinguishes professional cyclists from the rest of us isn’t solely their exceptional fitness; it’s the refined manner in which they transfer power to the pedals. Their pedal stroke appears remarkably smooth, efficient, and almost effortless, conserving energy and postponing fatigue during demanding rides. But can this elegant, high-performance style actually be developed through training? This article delves into the biomechanics of pedaling technique, revealing how elite riders achieve greater consistent power with less strain and offering insights on how you can integrate simple drills and focused practice to ride stronger, longer, and more efficiently.
Even from a distance, professional riders exhibit a distinctive and graceful cycling style that clearly sets them apart from amateur and recreational cyclists. This prompts the question: Is this difference attributable to their pedal stroke and technique? And if so, can we actively train to enhance our own cycling performance by adopting similar methods?
If you’ve ever had the chance to ride alongside a professional cyclist, whether active or retired, an unmistakable quality separates them from the peloton, and it goes beyond their superior fitness levels. Through countless hours on the bike, the rider and machine seem to merge into a fluid, unified entity, embodying a remarkable sense of fluidity and grace.
Cycling, and the act of pedaling, despite its constrained nature, is a complex motor skill involving the coordinated action of numerous muscles. It’s highly adaptable, combining various torque applications and cadences to achieve a desired power output.
You’ve likely encountered advice on training to refine your pedal stroke. The core principle is that a more efficient pedal stroke requires less energy, thereby delaying the onset of fatigue. Commonly suggested drills include one-legged pedaling, practicing extremely high cadences, and actively ‘pulling up’ during the upstroke, often visualized as scraping mud off your shoes.
For many years, scientists have explored whether professionals employ a fundamentally different pedaling technique. This is a crucial inquiry because if significant differences exist between a professional’s pedaling and an amateur’s, it would suggest that targeted training of the pedaling motion could be a viable path to improved cycling performance.
Scientific Insights into Professional Pedaling
A notable study by Garcia-López et al., published in the Journal of Sport Sciences in September 2016, tackled this very question. A primary challenge in such research is securing access to professional cyclists for laboratory studies, alongside the technical difficulty of instrumenting and accurately measuring the complete kinetics of the pedal stroke.
The Spanish research group successfully gained access to members of the former Euskatel-Euskadi WorldTour team, comparing their pedaling stroke against those of elite amateurs and regular club cyclists. The experimental setup involved:
- Participants: 11 professional cyclists from the Euskatel-Euskadi team, 13 “Elite” participants from a UCI Continental team, and 14 “Club” cyclists who competed and rode between 5,000 and 15,000 km annually.
- Protocol: After a warm-up, each participant completed five-minute efforts at 200, 250, and 300 W, all at 90 rpm, with six minutes of rest between efforts. The 300 W upper limit was chosen to ensure the club cyclists could complete all efforts.
- Timing: All cyclists were tested at the start of the competitive season (February-March). Nine of the professional cyclists were also re-tested at the beginning of their off-season (November) to observe any seasonal changes in their pedal stroke.
The study’s key analyses of pedaling kinetics focused on metrics such as the maximum and minimum torque generated during both the downstroke and upstroke, along with the proportion of the total pedal stroke exhibiting positive versus negative tangential force.
Key Findings from Stroke Analysis
The study’s results strongly indicate that professional cyclists do indeed possess a distinct pedal stroke compared to elite and club cyclists. Some of the significant differences observed included:
- Greater Positive Force: Professionals demonstrated a higher proportion of positive force throughout their pedal stroke, ranging from 1.5% to 3.3% more of the pedal stroke compared to elite and club cyclists.
- Smoother Torque Application: Professionals tended to exhibit lower maximal torque than elite and club cyclists across all three power outputs (200, 250, and 300 W). Combined with the greater positive force proportion, this suggests that professional cyclists maintain a smoother, more even pedal stroke, relying less on a single, massive peak burst of torque.
- Efficient Upstroke: Professionals displayed a superior ability to ‘unweight’ their legs during the upstroke phase, evidenced by lower minimum torque at all three power outputs compared to their elite and club counterparts.
- Joint Mobility: Regarding the different joints involved in pedaling, the primary difference across fitness levels appeared to be a progressively greater range of motion in the ankle joint with higher competitive levels, alongside a greater degree of hip flexion.
One particularly interesting revelation was the professionals’ ability to maintain a smoother and longer power phase within their pedal stroke, requiring less of a peak torque burst. This suggests that the power generation for a single pedal stroke might be more evenly distributed across a wider array of muscles, thereby reducing the risk of any specific muscle becoming overly stressed and prematurely fatigued.
Regarding the finding of lower minimum torque in professional cyclists, it’s worth noting that this might partly be attributed to a trend of slightly lower body mass and, consequently, lower limb mass in professionals, rather than solely systematic changes in the pedal stroke itself. The authors observed that, when factoring in weight changes throughout the preseason, no significant changes in minimum torque were seen when comparing pre- and post-season results in the professional group.
Conclusion
This study confirms that our visual observations are accurate: top professional cyclists do possess a different pedal stroke compared to the rest of us. This stroke is characterized by increased smoothness, with reduced fluctuations in maximum and minimum torque. Based on the range of motion data, this improved fluidity may be partly due to greater mobility in the ankle joint throughout the pedal stroke.
Therefore, focusing some off-season training on enhancing your pedal stroke can indeed be a worthwhile endeavor. By doing so, you can aspire to emulate the fluidity and style of top riders, preparing yourself for stronger, more efficient rides when you return outdoors regularly.
Ride strong and have fun!
