Maximal heart rate is estimated by subtracting your age from 240?

No, It is recommended that you exercise at 55% to 85% of your predicted maximum heart rate (220 minus your age)


How and why does aging affect the maximal heart rate?

Young children generally have a maximal heart rate approaching 220 beats per minute. This maximal rate falls throughout life. By age 60 maximal heart rate in a group of 100 men will average about 160 beats per minute. This fall in heart rate seems to be a linear process so that maximal heart rate can be estimated by the formula 220- AGE. This is an ESTIMATE, however. If we actually measure the maximal heart rates of those same 100 men during a maximal exercise test we would probably see a range of heart rates between 140 and 180. There is no strong evidence to suggest that training influences the decline in maximal heart rate. This reduction appears to be due to alterations in the cardiac electrical conduction system (SA node and Bundle of His), as well as down regulation of beta-1 receptors, which decreases the heart's sensitivity to catecholamine stimulation.

What is maximal heart rate?

: Maximal heart rate is the highest number of times per minuet that your heart can contract. In Humans the maximal heart rate is about 200 BPM. Sinus tachycardiac is a heart rate of more than 100 BPM. Fast heart rate decreases coronary blood flow fill leading to an increased demand of oxygen on the heart. This means that you should not keep your heart beating at its maximal rate for too long. Fibbrilation is a high heart rate which occurs in a disease of the heart that causes the electrical signals in the heart to become very rapid and irregular the heart rate for fibbrilation is about 300 -600 BPM. Dont worry though your heart cannot go into fibbrilation unless there is a heart disease which causes it to happen and a heart rate of 200 BPM is NOT fast enough to causes fibbrilation in the heart. : I hope you find this helpful : http://wiki.answers.com/Q/How_heart_works&alreadyAsked=1


What damage happens when your heart rate goes above 222?

It can causes heart damage, inchemia heart disease- very low cardiac output and coronary blood flow, fibbrilation.

Your resting heart rate should be between 60-100 beats per minute. If you are an athlete or train a lot, your resting heart rate could be lower. That is an average. Resting heart rate above 150 is tachycardia (fast). During exercise, you should shoot for between 40-60% of your heart rate max which is generally estimated by subtracting your age from 220. Example a 20 year old (220-20=200) would have a max heart rate of 200. You should be careful when starting exercise not to get your heart rate too close to max.
