Cadence Optimization: The Scientific Debate Between High vs. Low RPM

For road cycling enthusiasts in Taiwan, whether you’re tackling the long climbs of Balaka Road or charging through the switchbacks of Wuliaojian in Sanxia on the weekend, the degree of scientific rigor in your training often determines whether you can break your personal best (PB). This article will take a systematic, actionable approach to help you deeply understand the sports science principles behind “Cadence Optimization,” while incorporating Taiwan’s local riding environment, events (such as the Tour of East Coast), and climate conditions to provide a training mindset that can truly be put into practice.

Many cyclists’ biggest blind spot in training is mistaking “fatigue” for “effectiveness.” In reality, performance improvement comes from the complete cycle of Stimulus → Fatigue → Recovery → Supercompensation. If you simply keep accumulating fatigue without structured intensity distribution and recovery planning, your body will remain in a state of fatigue buildup, ultimately leading to stagnant or even declining performance. The goal of this article is to help you build a training framework where you “know exactly why you’re training this way.”

From here, we’ll start with the physiological mechanisms, then progressively move into actual workout plans, data interpretation, Taiwan route applications, common mistakes, and long-term planning—all substantive content that can be directly applied to your next training cycle.

1. The Underlying Exercise Physiology

To understand any cycling training method, you must first return to the body’s three energy systems:

For the vast majority of Taiwanese cyclists, riding long climbs like Balaka Road—which typically take one to two hours—is dominated by the aerobic system. This is why “Aerobic Base” is considered the foundation of the training pyramid—without a solid aerobic engine, any anaerobic capacity is merely a flash in the pan.

At the cellular level, long-term aerobic training brings several key adaptations:

• Increased mitochondrial density and volume: Mitochondria are the cell’s power plants; the more you have, the more ATP you can produce per unit of time.
• Capillarization: A denser capillary network around the muscles improves oxygen and nutrient delivery efficiency while accelerating metabolic waste clearance.
• Increased stroke volume: The heart pumps more blood per contraction, which lowers resting heart rate—this is why well-trained riders often have morning heart rates in the 40s.
• Rightward shift of lactate threshold (LT): At higher intensities, the body can still maintain the balance between lactate production and clearance, meaning you can “cruise” at faster speeds.

The value of understanding these mechanisms lies in this: when you know whether a particular workout is stimulating mitochondria or challenging lactate tolerance, you can more precisely judge “whether I should push hard today.” This is the biggest gap between amateur riders and those who simply ride casually.

2. Core Methods and Implementation Steps

2-1 Establish Your Baseline Data First

The first step in any scientific training approach is quantifying your current status. We recommend obtaining at least the following data:

1. FTP (Functional Threshold Power): Can be estimated via a 20-minute test (average power × 0.95) or a Ramp Test. This is the anchor point for all your power zones.
2. Maximum heart rate and resting heart rate: Maximum heart rate should ideally be measured during an actual hard climb, rather than using the rough 220-minus-age formula.
3. Body weight and power-to-weight ratio (W/kg): For long climbs like Balaka Road, W/kg is almost the decisive metric. A 65 kg rider with an FTP of 260W (4.0 W/kg) will be noticeably faster on pure climbs than an 80 kg rider with an FTP of 280W (3.5 W/kg).

2-2 Power Zone Reference

Using FTP as the 100% baseline, the commonly used seven-zone (Coggan model) framework is as follows:

2-3 A Sample Weekly Training Plan You Can Execute

Using an advanced rider who can train 8–10 hours per week as an example:

• Monday: Rest or 30 minutes of Z1 active recovery on the trainer.
• Tuesday: Threshold intervals—after a 15-minute warm-up, do 3 sets × 10 minutes at Z4 (5 minutes of Z1 recovery between sets).
• Wednesday: 90 minutes of pure Z2 aerobic riding, maintaining a cadence of 85–95 rpm.
• Thursday: VO2max intervals—5 sets × 4 minutes at Z5 (4 minutes of Z1 recovery between sets).
• Friday: Rest or easy recovery ride.
• Saturday: Long-distance ride, 3–4 hours, including Tempo climbing on Balaka Road.
• Sunday: 2 hours of Z2 social riding, with some technical skills practice thrown in.

The philosophy behind this plan is “Polarized Training”: approximately 80% of training volume falls in the easy Z1–Z2 range, and 20% falls at high intensity Z4 and above, deliberately avoiding the gray zone of Z3 where you’re “neither tired enough nor easy enough.” A substantial body of research shows that this distribution is the most efficient way to improve endurance performance.

3. Practical Application on Taiwan’s Local Routes

With the theory covered, let’s put it back into Taiwan’s real-world riding scenarios.

Balaka Road—The Ultimate Training Ground for Long-Climb Endurance

Balaka Road is a classic venue for testing your aerobic engine and pacing ability. The most common mistake first-timers make is going out too hard: pushing power into Z4 and above before you’ve even settled in, only to have your muscles blow up prematurely in the middle and later sections, forcing you to walk or stop for extended periods. The correct approach is to set your target power near the “overall average power” you can sustain (typically slightly below FTP, depending on climb length), and strictly manage it with a power meter or heart rate monitor, saving the “heroics” for the final three kilometers.

Guanwu and Hehuan Mountain—Comprehensive Tests of Intensity and Technique

• At Guanwu, you can practice Tempo (Z3) climbing, building the muscular endurance to sustain sub-threshold output over long durations.
• At Hehuan Mountain, the winding, undulating terrain is ideal for practicing cornering weight shifts and re-acceleration out of corners, which is crucial for events like the Tour of East Coast.

Local Considerations for Climate and Nutrition

Taiwan’s summers are hot and humid, with flatland temperatures frequently exceeding 35°C. Heat dissipation is a severely underestimated limiting factor. High temperatures cause heart rate to run noticeably higher at the same power output (cardiovascular drift). If you stubbornly pace by heart rate in these conditions, you’ll end up undertraining. We recommend using power as the primary metric and heart rate as secondary during summer long rides, supplementing with electrolyte-containing fluids every 15–20 minutes, and consuming 60–90 grams of carbohydrates per hour to avoid “bonking.”

In winter, at elevations above 3,000 meters on Balaka Road, temperatures can approach 0°C, making warmth and downhill wind chill another aspect that requires serious planning.

4. Data Interpretation and Advanced Monitoring

Once you start accumulating training data (ideally using the SRAM or KOM Cycling ecosystem), you can manage training load with more objective metrics. The three most commonly used concepts:

Practical interpretation principles:

• Gradual CTL increase: Keep weekly growth within 5–8 TSS/day; rising too fast is a precursor to injury and overtraining.
• Positive TSB: Indicates fresh form, suitable for racing or testing; athletes typically deliberately push TSB to +5 to +25 before a race.
• Prolonged deeply negative TSB: If it stays below −30 for several consecutive weeks, be highly alert to overreaching/overtraining.

Beyond load data, don’t ignore heart rate variability (HRV) and morning resting heart rate. When HRV is consistently low, morning pulse is abnormally elevated, and sleep quality declines, these are your body’s “I haven’t recovered yet” signals—worth listening to more than any rest day scheduled on a training plan.

Common Data Pitfalls

1. Overestimated FTP: Setting training zones based on a single test where you felt exceptional, causing every workout to be overloaded.
2. Looking only at average power, ignoring variability: The same 200W average, but with fluctuating “sawtooth power,” exacts a far higher physiological cost than steady output—this is exactly why NP (Normalized Power) exists.
3. Ignoring altitude and temperature context: 220W at 3,000 meters on Wuling carries a far greater physiological cost than 220W at sea level, due to lower oxygen availability.

5. Common Mistakes and How to Fix Them

Based on long-term observation of Taiwanese cyclists’ training patterns, the following mistakes are the most widespread and the ones you should most heed:

1. Moderate intensity every day (Junk Miles): Every ride is “somewhat tiring but not stimulating enough,” so over time you neither build aerobic base nor high-intensity capacity. The fix: strictly separate “easy days should be truly easy, hard days should be truly hard.”

2. Neglecting recovery: Treating rest days as laziness and forcing yourself to log rides every day. The fix: recovery is part of training; supercompensation happens during rest, not during training.

3. Equipment first, training second: Spending over a hundred thousand NT$ upgrading to carbon wheels, yet unwilling to invest time in structured workouts. The fix: for amateur riders, the engine (your body) has far more room for improvement than the equipment.

4. Only training what you’re good at: If you climb well, you only climb; if your sprint is weak, you never practice sprinting. The fix: use a pre-season fitness test to identify weaknesses and target them specifically.

5. Overtraining before a race: Still piling on volume the week before a race, then showing up on race day carrying full fatigue. The fix: 7–14 days before the race, do a “taper”—cut volume in half, retain a small amount of high-intensity stimulus, and let your body peak on race day.

Injury Prevention Reminder

Although cycling is a low-impact sport, patellofemoral pain syndrome (PFPS), iliotibial band syndrome (ITBS), and lower back pain are still very common, usually stemming from improper bike fitting or a sudden spike in training volume. Any new training plan should follow the “progressive overload principle,” and persistent pain should be addressed early rather than “ridden through.”

6. Putting It Into Your Long-Term Plan

No matter how well-designed a single workout is, its benefits are diminished if it isn’t placed within a periodization framework. A typical annual macrocycle can be divided into:

• Base period (8–12 weeks): Primarily high-volume Z2 aerobic work to build the engine, paired with strength training and skill refinement.
• Build period (6–8 weeks): Gradually introduce threshold and VO2max intervals to enhance specific capabilities.
• Peak period (2–3 weeks): High intensity, low volume, with a taper scheduled so form peaks at the target event.
• Transition / recovery period (2–4 weeks): Deliberately deload after the season ends, recharge mentally and physically, and avoid long-term accumulation leading to burnout.

Map this framework onto Taiwan’s race calendar: if your goal is the autumn Tour of East Coast (Huan Dong Hua), then summer is your build period and early autumn enters your peak period. This sequencing allows your hard training to translate into results on the most critical day.

Recommendations for Riders of Different Levels

7. FAQ

Q1: I don’t have a power meter. Can I still use this approach?
Yes. Although power is the most precise training tool, you can still use “heart rate + rating of perceived exertion (RPE)” as a substitute. Heart rate responds slowly and is easily affected by temperature and fatigue, so pairing it with RPE (self-rated on a 1–10 scale) makes it more reliable.

Q2: I can only train three times a week. What’s the most effective arrangement?
A recommended combination is “one long aerobic ride + one threshold/VO2max interval session + one moderate tempo ride,” concentrating your limited time on the highest-return stimuli while ensuring adequate recovery between sessions.

Q3: How long until I see progress?
Physiological adaptations typically require 6–8 weeks of consistent stimulus before they clearly show up in your data. Patience is the most underestimated ability in endurance sports—avoid testing FTP every week and doubting yourself.

Q4: Can indoor trainers and outdoor riding replace each other?
Indoor trainers (such as Shimano smart rollers) excel at “precise intensity control,” making them ideal for intervals; outdoor riding is irreplaceable for practicing bike handling, pacing, and mental toughness. The ideal approach is to use both as complements, not as an either/or choice.

Conclusion

Returning to the core of this article: “Cadence optimization” is not some magical training plan or expensive equipment—it’s a long-term mindset of “understanding the principles → quantifying your current state → structured execution → data feedback → continuous adjustment.” The next time you ride the long climb up Balaka Road, I hope you won’t just grind through on feel alone, but will clearly know which energy system you’re training at that moment, why you’re pacing this way, and how this ride fits into the blueprint of your entire season.

Training is a long-term dialogue with yourself. May you ride smarter, healthier, and faster on every road in Taiwan. Before your next ride, ask yourself one question: “What is the purpose of this ride today?” If you can answer it clearly, you’re already ahead of most riders.

This article is for training knowledge sharing; individual training plans should still be adjusted according to personal fitness, health conditions, and professional coach recommendations. If you have cardiovascular disease or existing injuries, consult a physician before starting any high-intensity training.
