Benefits of Physical Exercise
Image via WikipediaThere are two types of physical exercise, Aerobic and Anaerobic. Anaerobic exercise triggers anaerobic metabolism, when the exercise is intense enough. It involves high intensity activity lasting 2 minutes and used by athletes wishing to build power and muscle mass. Muscles will develop differently in anaerobic exercise resulting in greater performance in short duration.
On the other hand, aerobic exercise also know as cardiovascular exercise, involves low intensity activity performed over longer periods of time. These activities include, walking, swimming, cycling and jogging, which need a lot of oxygen to generate the energy level required for prolonged exercise. Aerobic exercise makes the lungs work harder as the body’s need for oxygen is increased.
The benefits of physical exercise includes:
- Building and maintaining health bone density
- Joint mobility
- Maintaining healthy weight
- Reducing surgical risks
- Strengthening the immune system
- Muscle strength
- Feeling good about one self through being physically and mentally fit, thus reducing chances of depression
- In aerobic exercise there’s an increased energy level
- Also, in aerobic exercise there’s reduced blood pressure, resting heart rate and
risk of stroke or heart attack.
Besides, exercising regularly is likely to make us live longer and enjoy a better quality of life. In fact, studies show that being physically unfit is just as harmful as smoking in terms of lowering life expectancy. Regular exercise is a great benefit for mental and emotional well-being. The chemicals and hormones released in the brain through exercise protects against stress and promotes happiness. It doesn’t even cost much in terms of money or time to exercise. Half an hour a day is enough and can be split into two 15 minutes of out indoors or outdoors. Half an hour of low paced jogging can burn around 300 calories. This could be a contribution towards achieving the necessary calorie deficit to lose weight, or alternatively it can earn you a bar of chocolate that you feel less guilty about eating. For good cardiovascular fitness it is generally recommended to exercise 3 to 5 times a week and for 30-60 minutes, not including warming up at the start and cooling down at the end.
