Defintion for Critical Speed

The speed at which an athlete can sustain exercise without fatigue over a prolonged period, representing the threshold between aerobic and anaerobic energy systems.

Long Definition

Critical Speed (CS) is the highest running speed a runner can maintain indefinitely without fatigue. It represents the threshold between sustainable and unsustainable effort. CS is determined through time trials or specific tests and is crucial for pacing strategies. For example, if a runner's CS is 5 m/s, they can sustain this pace for extended periods. Understanding CS helps runners optimize training, improve endurance, and set realistic race goals. It matters because training at or near CS can enhance aerobic capacity and delay fatigue, crucial for long-distance events.

Kaizen Insights

Kaizen uses Critical Speed to assess an athlete's endurance capacity and predict performance in longer distance events. It helps in setting training intensities and pacing strategies.
