Aerobic activities and your heart rate
Heart rate is widely accepted as a good method for measuring intensity during running, swimming, cycling, and other aerobic activities. Exercise that doesn't raise your heart rate to a certain level and keep it there for 20 minutes won't contribute significantly to cardiovascular fitness. The heart rate you should maintain is called your Target Heart Rate. There are several ways of arriving at this figure. One of the simplest is: maximum heart rate (220 - age) x 70%. Thus, the target heart rate for a 40 year-old would be 126. In this example for this 40 year old to get a cardiovascular effect the individual would need to keep their heart rate at or above 126 beats per minute to get a cardiovascular effect. Note: Although 70% was used in this example, the heart rate range needed to achieve results falls between 60% and 85% of your maximum heart rate. If you are just beginning your exercise program, your target heart rate range should be roughly at 60% of your maximum heart rate. As you become more conditioned (or if you are already in good cardiovascular shape) you can increase your target heart rate to 70%-85% of your maximum heart rate. Remember, your target heart rate is only a guide. When checking heart rate during a workout, take your pulse within five seconds after interrupting exercise because it starts to go down once you stop moving. Count pulse for 10 seconds and multiply by six to get the per-minute rate.
Sole treadmills such as F80 and F85 model year 2012-2013 come with heart rate programs.
With the proper use of a heart rate monitor, many people find that their usual choice of exercise intensity was either too high or too low and exercise is much more enjoyable by maintaining their heart rate in the desired benefit range. To determine the benefit range in which you wish to train, you must first determine your Maximum Heart Rate. This can be accomplished by using the following formula: 220 minus yourage. This will give you the Maximum Heart Rate (MHR)for someone of your age.
To determine the effective heart rate range for specific goals you simply calculate a percentage your MHR. Your Heart rate training zone is 50% to 90% of your maximum heart rate. 60% of your MHR is the zone that burns fat while 80% is for strengthening the cardio vascular system. This 60% to 80% is the zone to stay in for maximum benefit.
