Das Glossar – erklärt, ohne Bullshit
Begriffe aus Radsport und Laufen – FTP, CTL, TSS, Sweet Spot, Zone 2 – einfach erklärt: was sie bedeuten und wie du sie nutzt.
Power
CP (Critical Power)
The highest power you can sustain indefinitely from aerobic metabolism alone.
Mehr erfahrenFTP (Functional Threshold Power)
The highest power, in watts, you can sustain for roughly an hour.
Mehr erfahrenNP (Normalized Power)
A weighted average of power that reflects the physiological cost of a variable-intensity ride.
Mehr erfahrenSweet Spot
Training intensity at roughly 88–94% of FTP — high productivity per unit of fatigue.
Mehr erfahrenThreshold
Intensity at or around FTP/LTHR — the boundary between sustainable and unsustainable effort.
Mehr erfahrenVO2 max
The maximum volume of oxygen your body can consume and use during intense exercise.
Mehr erfahrenW' (W-prime)
The amount of work, in kilojoules, you can do above Critical Power before exhaustion.
Mehr erfahrenHeart rate
Training load
ATL (Acute Training Load)
A 7-day weighted average of your daily training stress — a proxy for fatigue.
Mehr erfahrenCTL (Chronic Training Load)
A 42-day weighted average of your daily training stress — a proxy for fitness.
Mehr erfahrenIF (Intensity Factor)
A workout's Normalized Power divided by your FTP — a simple measure of how hard the ride was relative to threshold.
Mehr erfahrenTSB (Training Stress Balance)
CTL minus ATL — a single number that estimates how fresh or fatigued you are.
Mehr erfahrenTSS (Training Stress Score)
A single number summarizing how much physiological stress a workout produced, scaled to FTP.
Mehr erfahrenPace & effort
Cadence
How many times your legs complete a full pedal stroke per minute (cycling) or steps per minute (running).
Mehr erfahrenNegative split
Completing the second half of an effort or race faster than the first.
Mehr erfahrenZone 2
Easy endurance riding at 55–75% of FTP — the foundation of aerobic fitness.
