The Modern Science of Periodized Training: A Comparison of Three Major Models

Periodization is the science of systematically arranging training load to achieve peak performance at a specific time. Since Soviet sports scientist Tudor Bompa introduced it in the 1950s, periodization theory has evolved into several distinct models, each with its own scientific basis and applicable contexts.

Basic Concepts of Periodized Training

Why Do We Need Periodization?

Supercompensation Theory:

1. Training imposes stress (disruptive stimulus)
2. Recovery phase (adaptation occurs)
3. Supercompensation (capacity exceeds pre-training levels)
4. Return to baseline (if no further stimulus)

The essence of periodization is: schedule the next training session or race during Phase 3 (the supercompensation peak) to maximize cumulative progress.

Basic Terminology

Three Mainstream Periodization Models

Model One: Traditional Linear Periodization

History: Widely used by Soviet and Eastern European athletes in the 1960s-1970s

Principle: Training volume gradually decreases while intensity gradually increases, focusing toward race day

Typical Structure (12 weeks):

Best suited for: Riders with only one or two major races per year; riders with less training experience

Advantages: Clear structure, easy to execute; well-supported by scientific evidence

Disadvantages: Not suitable for multiple race goals in one year; long base phase can be monotonous early on

Model Two: Block Periodization

Developed by: Issurin (proposed in 2008)

Core concept: Training capacities are divided into “blocks,” with each block focusing on developing a few capacities before stacking them

Three block types:

Typical cycling season arrangement:

A block (4 weeks) → B block (3 weeks) → C block (2 weeks) → Race
→ 1 week rest →
A block (3 weeks) → B block (2 weeks) → C block (2 weeks) → Second race

Best suited for: Riders with multiple different race goals per year; riders with moderate training experience

Advantages: Flexible, can accommodate multiple race schedules; each block has a clear focus

Disadvantages: Complex planning; requires precise training control

Model Three: Reverse Periodization

Concept: Opposite of traditional periodization—build high-intensity capacity first, then develop aerobic endurance

Principle: Adaptations from high-intensity training occur faster; intensity first establishes “neuromuscular efficiency,” then high-volume aerobic training amplifies these benefits

Typical Structure:

Best suited for: Races in late summer to early autumn (Taiwan’s Wuling, KOM series); advanced riders with sufficient aerobic base

Advantages: Highly effective for cycling time-trial type events; better motivation maintenance (early training intensity is high, results are visible)

Disadvantages: Less scientific literature compared to traditional models; higher risk for those with weak foundations

Periodization Recommendations for Taiwanese Riders

Typical Taiwanese Race Calendar

Recommended approach: Block periodization, with Taiwan’s major autumn races as the peak, designing 3-4 block cycles per season.

Conclusion

There is no single universally correct model of periodized training. The best periodization is the one you can execute consistently. Understand the principles of the three major models, and choose or combine the approach that fits your race schedule, training time, and current abilities—this is what truly scientific training planning looks like.
