Introduction To Heart Rate Zones

People workout due to several kinds of motives. Some would like to drop some pounds, a few wish to build larger muscles, others want the feeling of adrenaline and also, most exercise to be healthy and be well balanced. Most exercise or training plans are based on intensity. Intensity is described by five heart rate zones, namely healthy heart zone, fitness zone, aerobic zone, anaerobic zone and red-line zone.

The healthy heart zone, sometimes called the comfort zone is the safest and least difficult. Exercising in this zone (by brisk walking for example) improves the pumping ability of the heart and helps decrease body fat, blood pressure, and cholesterol. This zone eats away 10 percent carbohydrates, 5percent protein and eighty-five percent fat.

The fitness zone, also called the fat-burning zone, is regarded as the most efficient for overall cardiovascular health. More calories is used up in this zone because the workouts are more rigorous, such as jogging (against brisk walking in zone one). This zone eats away eighty-fivepercent fat, 5percent protein, and 10 percent carbohydrate.

The third heart zone is referred to as the aerobic zone. Since this zone strives for endurance, workouts are even more rigorous and intense. An example of exercise in this zone is running. It increases the number and size of the blood vessels and thus improves the individual’s circulatory system. It also boosts the respiratory system as it increases a person’s lung capacity.

The fourth heart rate zone is called the anaerobic zone, also referred to as the threshold zone. Running fast is an example exercise. Around 10 to 20 minutes of workout is usually allotted in this zone. At this time, the muscles are not supplied with sufficient blood because the heart cannot pump effectively. As a response, the muscles contract without the use of oxygen and so this is when the person feels the “burn”.

The red-line zone is the fifth heart rate zone where you can’t go any higher. Exercising at such very high intensity requires the guidance of a doctor. The best fitness training benefits can be obtained by spending 20-60 minutes of workout in this zone.

So which heart rate zone best suits you? Bear in mind that choosing the right zone is a major factor in any exercise. To get the best results, it is advised that you try different workouts and make the most out of each heart rate zone.
