Final answer:
The average pulse rate for adult males at rest is between 60 and 100 bpm. Maximum heart rates can be estimated as 220 minus one's age, and rates above or below the average range are known as tachycardia and bradycardia, respectively.
Step-by-step explanation:
For adult males, the average pulse rate, also known as heart rate (HR), falls within the range of 60 to 100 beats per minute (bpm) when at rest. This range is considered normal for a healthy adult. Maximum HR can be estimated with the formula 220 minus the person's age. For example, a 40-year-old man might have a maximum HR of about 180 bpm. However, it's important to remember that this is an estimate, and individual maximum heart rates can vary. Individuals with bradycardia experience heart rates below 60 bpm, while those with tachycardia have rates above 100 bpm in a resting state. Athletes often have lower resting HRs due to their high levels of fitness.
