Benefits of Aerobic and Anaerobic Exercise


Benefits of Aerobic and Anaerobic Exercise

            Aerobic exercise is a physical exercise of relatively low intensity that depends primarily on the aerobic energy-generating process. Aerobic literally means "living in air", and refers to the use of oxygen to adequately meet energy demands during exercise via aerobic metabolism. Generally, light-to-moderate intensity activities that are sufficiently supported by aerobic metabolism can be performed for extended periods of time. The intensity should be between 60 and 85% of maximum heart rate.

Aerobic exercise comprises innumerable forms. In general, it is performed at a moderate level of intensity over a relatively long period of time. For example, running a long distance at a moderate pace is an aerobic exercise, but sprinting is not. Playing singles tennis, with near-continuous motion, is generally considered aerobic activity. The benefits of anaerobic exercise are powerful, and anaerobic exercise needs to be a part of your fitness program. Anaerobic exercise is high intensity muscular activity that lasts for a short period of time.

Aerobic Exercise Benefits:

The benefits of doing regular aerobic exercise are:

1) Strengthening the muscles involved in respiration, to facilitate the flow of air in and out of the lungs

2) Strengthening and enlarging the heart muscle, to improve its pumping efficiency and reduce the resting heart rate, known as aerobic conditioning

3) Strengthening muscles throughout the body

4) Improving circulation efficiency and reducing blood pressure

5) Increasing the total number of red blood cells in the body, facilitating transport of oxygen

6) Improved mental health, including reducing stress and lowering the incidence of depression

7) Reducing the risk for diabetes.

As a result, aerobic exercise can reduce the risk of death due to cardiovascular problems. In addition, high-impact aerobic activities (such as jogging or jumping rope) can stimulate bone growth, as well as reduce the risk of osteoporosis for both men and women.

Anaerobic Exercise Benefits:

Anaerobic means "without oxygen," so your body does not use oxygen to help produce energy when you exercise anaerobically like it does when you exercise aerobically. The benefits of doing regular anaerobic exercise are:

1) Increase insulin sensitivity by increasing glucose uptake by muscles and improving the ability to store glucose

2) Contribute to healthy body composition of lean muscle and fat

3) Decrease body fat by raising metabolism

4) Increase muscle mass

5) Builds healthy bones, muscles and joints

6) Improves bone density and strength

7) Enhancing the speed at which muscles recover from high intensity exercise

Both Aerobic and Anaerobic can help decrease dose of glucose lowering medications or even need for glucose lowering medications. And they can lower glucose during exercise and for several hours after exercise.
