De woordenlijst, zonder bullshit uitgelegd
Fiets- en hardlooptermen - FTP, CTL, TSS, sweet spot, Zone 2 - simpel uitgelegd, met wat ze betekenen en hoe je ze gebruikt.
Power
CP (Critical Power)
The highest power you can sustain indefinitely from aerobic metabolism alone.
Lees meerFTP (Functional Threshold Power)
The highest power, in watts, you can sustain for roughly an hour.
Lees meerNP (Normalized Power)
A weighted average of power that reflects the physiological cost of a variable-intensity ride.
Lees meerSweet Spot
Training intensity at roughly 88–94% of FTP — high productivity per unit of fatigue.
Lees meerThreshold
Intensity at or around FTP/LTHR — the boundary between sustainable and unsustainable effort.
Lees meerVO2 max
The maximum volume of oxygen your body can consume and use during intense exercise.
Lees meerW' (W-prime)
The amount of work, in kilojoules, you can do above Critical Power before exhaustion.
Lees meerHeart rate
Training load
ATL (Acute Training Load)
A 7-day weighted average of your daily training stress — a proxy for fatigue.
Lees meerCTL (Chronic Training Load)
A 42-day weighted average of your daily training stress — a proxy for fitness.
Lees meerIF (Intensity Factor)
A workout's Normalized Power divided by your FTP — a simple measure of how hard the ride was relative to threshold.
Lees meerTSB (Training Stress Balance)
CTL minus ATL — a single number that estimates how fresh or fatigued you are.
Lees meerTSS (Training Stress Score)
A single number summarizing how much physiological stress a workout produced, scaled to FTP.
Lees meerPace & effort
Cadence
How many times your legs complete a full pedal stroke per minute (cycling) or steps per minute (running).
Lees meerNegative split
Completing the second half of an effort or race faster than the first.
Lees meerZone 2
Easy endurance riding at 55–75% of FTP — the foundation of aerobic fitness.
