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.
Submaximal usually equates to about 70-85 percent of maximal heart rate (MHR).
Your maximal heart rate is 220 - MINUS your age. In most human their MHR is about 200- 220 BPM. Maximal heart rate is the highest number of times per minuet that you heart could contract during maximal physical exersion. It is unlikely for your heart to go into Fibrillation at heart rates of 200 - 250 BPM. Fibrillation occurs at heart rates of 300- 600 BPM and can be causes by Heart disease Electrical shock Heart attacks Heart Arrhythmia
depressants affect the heart rate by its heart rate
Your maximal heart rate is 202 BPM To work out your maximal heart rate you need to do a simple caluclation 220- minus YOUR AGE IN YEARS For example 220 - 20 = 200220-10= 210
The heart rate in the human body doesn't actually affect the adrenal glands. Its the other way around. The adrenal glands affect the heart rate by rising the rate over what it actually should be.
Submaximal usually equates to about 70-85 percent of maximal heart rate (MHR).
At 17 your maximal heart rate is 203 BPM. I would surgest that you visit your local hospital immedatly or call 999 Fribbrilation can occur if the heart goes over your maximal rate To calculate your maximal heart rate you need to subtract your age from the number 220 For more information please contact me Elliottcollins@hotmail.co.ukHow_heart_works
Subtract your age by 220
Your maximal heart rate is 220 - MINUS your age. In most human their MHR is about 200- 220 BPM.

Maximal heart rate is the highest number of times per minuet that your heart could contract within one minuet. A heart rate for an senior is about 120- 160 BPM
depressants affect the heart rate by its heart rate
Heart rate monitors are used to monitor heart rate on a longer-time basis. You can buy heart rate monitors between £10-500. You can use them whilst you are exercising so that you avoid the risks of exceeding your maximal heart rate.

this is a training system which raises an individual's pulse rate from 60% to 80% of his Maximal Heart Rate (MHR).
220 in max fisical activity eg sports
It increases your heart rate.
