What is the Anaerobic Threshold?
The anaerobic threshold is the point during exercise when your body’s demand for oxygen exceeds its ability to supply it. At this point, your muscles start relying more on anaerobic metabolism, producing energy without oxygen. The anaerobic threshold marks the transition from sustainable exercise to a more intense, unsustainable effort.
Why is the Anaerobic Threshold Important in Cycling?
Knowing your anaerobic threshold is crucial for optimizing your cycling performance. By training at or just below this threshold, you can improve your body’s efficiency in clearing lactate (a byproduct of anaerobic metabolism) and increase your endurance. Additionally, by maintaining a steady effort below your anaerobic threshold during long rides, you can delay fatigue and improve overall performance.
Methods to Calculate the Anaerobic Threshold
There are several methods to determine your anaerobic threshold in cycling. Here are two commonly used ones:
- Field Test: This method involves a high-intensity effort that lasts around 30 minutes. Start with a proper warm-up, then ride as hard as you can sustain for the given duration. Your average heart rate or power output during the last 20 minutes of the effort is a good estimate of your anaerobic threshold.
- Blood Lactate Testing: This method involves taking blood samples at various stages of exercise intensity and measuring the lactate levels. The point at which lactate levels sharply increase above the baseline signifies the anaerobic threshold.
Understanding Your Anaerobic Threshold Results
Once you have determined your anaerobic threshold, you can use this information to set training zones and improve your cycling performance. Training just below this threshold for extended periods can help increase your body’s ability to sustain higher efforts, while training above it can improve your anaerobic capacity.
Calculating your anaerobic threshold in cycling is essential for optimizing your training and performance. By knowing your threshold, you can plan your rides, set appropriate training zones, and improve your endurance and overall performance. Whether you choose a field test or blood lactate testing, understanding your anaerobic threshold will take your cycling to the next level.
