Calculated thresholds are obtained using the Karvonen formula as follows
Karvonen formula: heart rate reserve X power (%) + resting heart rate
The maximum heart rate is 205 – 1/2 x age, so my estimated maximum heart rate, at 27 years old, is about 192. So my heart rate reserve is 192-48=144.
The calculated aerobic and anaerobic thresholds are therefore obtained as follows.
So my calculated aerobic threshold would be (192 – 48) x 0.7 + 48 or 150. My anaerobic threshold is (192 – 48) x 0.9 + 48, or 178. The treadmill threshold test gave me an aerobic threshold of 158 and an anaerobic threshold of 178, so the calculated value for the aerobic threshold is slightly off, but the anaerobic threshold is exactly the same as the lactate-based threshold test.
«An endurance athlete’s training should be 70-80% basic endurance, which is a LOT.»
