骑行和跑步术语——FTP、CTL、TSS、燃脂区、Zone 2——用大白话讲清楚是什么、怎么用。
Power
CP (Critical Power)
The highest power you can sustain indefinitely from aerobic metabolism alone.
阅读更多FTP (Functional Threshold Power)
The highest power, in watts, you can sustain for roughly an hour.
阅读更多NP (Normalized Power)
A weighted average of power that reflects the physiological cost of a variable-intensity ride.
阅读更多Sweet Spot
Training intensity at roughly 88–94% of FTP — high productivity per unit of fatigue.
阅读更多Threshold
Intensity at or around FTP/LTHR — the boundary between sustainable and unsustainable effort.
阅读更多VO2 max
The maximum volume of oxygen your body can consume and use during intense exercise.
阅读更多W' (W-prime)
The amount of work, in kilojoules, you can do above Critical Power before exhaustion.
阅读更多Heart rate
Training load
ATL (Acute Training Load)
A 7-day weighted average of your daily training stress — a proxy for fatigue.
阅读更多CTL (Chronic Training Load)
A 42-day weighted average of your daily training stress — a proxy for fitness.
阅读更多IF (Intensity Factor)
A workout's Normalized Power divided by your FTP — a simple measure of how hard the ride was relative to threshold.
阅读更多TSB (Training Stress Balance)
CTL minus ATL — a single number that estimates how fresh or fatigued you are.
阅读更多TSS (Training Stress Score)
A single number summarizing how much physiological stress a workout produced, scaled to FTP.
