Kynnystehon

Kynnystehon is a Finnish term that translates to "threshold power." It refers to the amount of power a cyclist can sustain for a specific, but short, duration, typically around one hour. This metric is a key indicator of a cyclist's aerobic capacity and their ability to perform at high intensities for extended periods. It is often used in training and performance analysis to assess a rider's fitness level and to set appropriate training zones.

Understanding kynnystehon is crucial for both amateur and professional cyclists. It helps in designing training programs that target specific physiological adaptations. For instance, training sessions aimed at improving kynnystehon often involve intervals at or near this power output. The higher a cyclist's kynnystehon, the better their endurance and sustained power output will be, which is vital for competitive cycling events.

This concept is closely related to other physiological markers like Functional Threshold Power (FTP), which is typically measured over 20 minutes. Kynnystehon, being a shorter duration, generally represents a higher power output than FTP. However, the exact duration for kynnystehon can vary slightly depending on the context or the specific training methodology being used. It is a valuable tool for tracking progress and making informed decisions about training intensity and duration.
