A tool used to determine training intensity levels based on functional threshold power (FTP) helps cyclists optimize their workouts by providing personalized training zones. These zones, often represented as percentages of FTP, correspond to different physiological states and training adaptations, from active recovery to maximum effort. For example, a zone 2 workout might target endurance, while a zone 5 workout focuses on developing maximum power output.
Structured training based on these personalized zones leads to more effective and efficient progress. By understanding their physiological responses to different intensities, athletes can avoid overtraining, target specific weaknesses, and maximize performance gains. Historically, training intensity was often guided by perceived exertion, a subjective and less precise method. The advent of power meters and associated analytical tools allows for a more scientific and data-driven approach.
