To calculate the anaerobic threshold:
\[ \text{AT} = (220 - \text{A}) \times 0.875 \]
Where:
An anaerobic threshold is defined as the point at which the human body switches from aerobic to anaerobic metabolism. The threshold is reached when a person's heart rate reaches 85-90% of their maximum heart rate.
Let's assume the following value:
Using the formula:
\[ \text{AT} = (220 - 30) \times 0.875 = 165.00 \, \text{BPM} \]
The Anaerobic Threshold is 165.00 BPM.
Let's assume the following value:
Using the formula:
\[ \text{AT} = (220 - 45) \times 0.875 = 152.88 \, \text{BPM} \]
The Anaerobic Threshold is 152.88 BPM.
