Cardiovascular Exercise Principles and Guidelines: Part One *

For maximum effectiveness and safety, cardiovascular exercise has specific instructions on the frequency, duration, and intensity. These are the three important components of cardiovascular exercise that you really need to understand and implement in your program. In addition, your cardiovascular program should include a warm-up, a cool-down, and stretching of the primary muscles used in the exercise. This article is part one of a two part series discussing the very important principles and guidelines of a safe and effective cardiovascular exercise program. Part one will explain the proper methods of warming-up, stretching, and cooling-down and discuss the frequency and duration of a sound cardiovascular routine. Part two will discuss how to monitor exercise intensity and heart zone training.

Warming Up and Stretching
One very common mistake is stretching before muscles are warmed-up. It is important to stretch after your muscles are warm (after blood has circulated through them). Never stretch a cold muscle. First warm up. A warm-up should be done for at least 5-10 minutes at a low intensity. Usually, the warm-up is done by doing the same activity as the cardiovascular workout but at an intensity of 50-60% of maximum heart rate (max HR). After you've warmed-up for 5-10 minutes at a relatively low intensity, your muscles should be warm. To prevent injury and to improve your performance, you should stretch the primary muscles used in the warm up before proceeding to the cardiovascular exercise.

Cooling Down
The cool down is similar to the warm-up in that it should last 5-10 minutes and be done at a low intensity (50-60% of max HR). After you have completed your cardiovascular exercise and cooled-down properly, it is now important that you stretch the primary muscles being used. Warming-up, stretching, and cooling-down are very important to every exercise session. They not only help your performance levels and produce better results, they also drastically decrease your risk of injury.

Frequency of Exercise
The first component of cardiovascular exercise is frequency of the exercise, which refers to the number of exercise sessions per week. To improve both cardiovascular fitness and to decrease body fat or maintain body fat at optimum levels, you should exercise (cardiovascularly) at least three days a week. The American College of Sports Medicine recommends three to five days a week for most cardiovascular programs. Those of you who are very out of shape and/or who are overweight and doing weight-bearing cardiovascular exercise such as an aerobics class or jogging, might want to have at least 36 to 48 hours of rest between workouts to prevent an injury and to promote adequate bone and joint stress recovery.

Hi Nice Blog . I don't really know a lot about cardiovascular system information or art, but that's just my 2 cents. Really great job though, Krudman! Keep up the good work!
