Anaerobic threshold weight loss
Runners want to increase their aerobic threshold because this will enable them to run faster for longer before they tip into anaerobic metabolism which cannot be sustained for as long. When it comes to strength training, intensity is measured by how much weight you are carrying, how many repetitions you are carrying this weight and what rest intervals you have. Cardiovascular exercises compliment strength training and this is where you can use a definitive method such as target heart rate for weight loss to maximize fat loss. Target heart rate for weight loss applies mainly to cardiovascular exercises. Your body behaves very differently in each of these heart rate zones. When you run at close to your anaerobic threshold, running should be hard but not uncomfortable. Understanding target heart rate for weight loss When you do cardio exercises, your heart rate will increase. How to measure heart rate The most effective way of measuring heart rate is by using a heart rate monitor. The pace which corresponds to your aerobic threshold is generally around your marathon pace. Some runners observe a change in their breathing rhythm at the anaerobic threshold, from one breath for every four steps to one breath for every two steps. There is some controversy about whether there really is a level of exercise intensity at which lactic acid in the bloodstream begins to increase. In Chapter 7 we discussed the different ways that the body can convert stored energy into motion. The anaerobic threshold is defined as the level of exercise intensity at which lactic acid builds up in the body faster than it can be cleared away. Target heart rate for weight loss is most suitable for cardiovascular type exercises such as running or cycling. On this view, the anaerobic threshold is simply point at which the lactic acid accumulation becomes noticeable to the runner.
The aerobic threshold is the level of effort at which anaerobic energy pathways start to be a significant part of energy production. Target heart rate for weight loss applies mainly to cardiovascular exercises. It is relatively slow at producing energy, and therefore cannot be used when a lot of energy is needed quickly. As we shall see later, this is about 70% of VO 2 max, or about 75% of your working heart rate. It is, however, the main energy system used for long distance running. This is a device that you can wrap around your chest and it sends signals to the hear rate the monitor that is worn on the wrist. With the information provided here, you could use target heart rate for weight loss to maximize the efficiency and effectiveness of your cardiovascular exercises. By that definition, the target heart rate for weight loss is the zone in which your exercise efforts will give you the most amount of fat loss. There is evidence that lactic acid levels increase smoothly as exercise becomes more intense, and there does not appear to be an identifiable discontinuity or kink in the curve. The picture on the right is the typical heart rate chart that you may have seen in gyms. So if your age is 40, your maximum heart rate should theoretically be 180. You can determine the zone by assessing your maximal heart rate and then doing a rough calculation to assess the heart range zone that you want to be within. For this reason, it is also sometimes called the lactate threshold or lactate turnpoint (LT). The increase in heart rate is usually proportional to the intensity of the cardio exercise. Understanding heart rate zones Researchers have grouped heart rate zones. The aerobic energy system uses oxygen, and burns carbohydrate, fats and proteins.
