Useful tools to establish power and heart rate performance metrics.
Intensity Factor (IF) in cycling is a metric that quantifies the relative intensity of a workout compared to an athlete's Functional Threshold Power (FTP). It's calculated by dividing the normalized power (the average power output adjusted for fluctuations in intensity) of a ride by the athlete's FTP. IF provides insights into how challenging a workout was in relation to the athlete's sustainable power output, helping to gauge the physiological stress experienced during the ride. This metric is crucial for tailoring training sessions to specific intensity levels, optimizing performance gains, and avoiding overexertion or undertraining.
