Cardiovascular Activities Essay, Research Paper
The term aerobic was made popular by Dr. Kenneth Cooper in the late 1960s. The name was derived from Greek roots — aero, or air; and bios, or life. Since aerobic training plays a role in the prevention of cardiovascular disease, it’s often referred to as cardiovascular training. In order for an activity to be aerobic it must be rhythmic in its nature, use the large muscle groups and be continuously maintained for 20 to 60 minutes. It must also challenge the heart and lungs, but without overdoing it. Walking, hiking, swimming, running, cycling, rope skipping, rowing, stair climbing and group fitness classes such as low impact aerobics and indoor cycling are all aerobic.
What happens with aerobic training is that oxygen is continuously delivered to your muscles. Sprinting to the bus is admirable and impressive, but it is NOT an aerobic activity. It is considered an anaerobic activity, which means “without air.” This is because sprinting lasts for only a short amount of time, while a true cardiovascular activity would take place over a longer time period.
An example of anaerobic exercising would be something that is strenuous, such as running up a steep hill. There is a burning in your legs because the oxygen is no longer being delivered to your muscles. Your anaerobic system is designed only for those short bursts of intense activity but regular aerobic training will improve your anaerobic performance. You will probably shape up in a month or two. Supermarket shopping, on the other hand, will burn some calories, but it’s not rigorous enough to be considered aerobic.
Cardiovascular or aerobic activities are very important in living a healthy lifestyle. Almost everyone can fit easy and enjoyable activities into their regimen. It can be anything, such as, walking, hiking, jogging, bicycling, rowing, swimming and even water aerobics. With so many choices to chose from, cardiovascular exercising is the way to go!
