A genetically determined, task-specific rate at which the heart beats. Training does not increase maximum heart rate, but knowledge of one’s maximum heart rate may be used to determine target heart rate training zones.
In addition to the above methodology, other common HRmax formulae may better estimate your maximum heart rate. For example, Tanaka's equation is another well-known correlation based on a group of healthy men and women (3).
Phelan recommends that most people starting an exercise regimen keep their heart rate in a moderate range, at about 50 to 75 percent of their maximum heart rate. People with heart disease or those at significantly greater risk may start at a lower intensity, while healthier adults might aim for higher target heart rates (see chart).
Let's remember the minimum physical activity for maximum health benefit: walking 10,000 steps each day, 30 minutes a week of resistance exercise, and 20 minutes three times a week of movement that puts you at 80 percent of your age-adjusted maximum heart rate. (That's about 220 minus your age for men; 206 minus 88 percent of your age for women.) So if you use a heart rate monitor--the version with a chest strap tends to be more accurate--see that you are indeed getting to that target heart rate for at least 20 continuous minutes, three times a week, and you'll be golden.
Effort, measured in MYZONE Effort Points (MEPs), accumulates for every minute of activity the user expends based on the maximum heart rate. The device also calculates calories burned and the duration of each workout session.
