Essay on The Importance of Physical Fitness

Enhancing cardiac output allows you to maintain lower heart rates during physical activity. For example, at the start of a program you may have a heart rate of 150 beats per minute while running at a 6 mph pace. After three or more months of training increased cardiac output enables you to sustain the same running intensity at a lower heart rate such as 125 beats per

These components include aerobic power, which can be typically described as VO2 max, this is the maximal amount of oxygen the body can take in and use efficiently. The amount of oxygen taken in can be influenced greatly by the cardiovascular systems ability to deliver oxygenated blood to exercising muscles, the lungs ability to oxygenate the blood and the muscles ability to use the oxygen and extract it for sustained contractions. Disease and inactivity therefore can impair or inhibit these factors consequently reducing a persons ability to function.

Physical Fitness: Continue to workout on your own to maintain a healthy lifestyle and remember the health benefits of exercise and physical activity.

35. Resting Heart Rate It’s important that you know this so you know when something isn’t right, so check your pulse after you get up and count the beats for 10 seconds, now multiply that number by six. It should be somewhere in the range of 60 – 80, though it may be lower for athletes.

Exercise is another key to maintain a healthy heart and cardiovascular system. The American Heart Association recommends 150-minutes of moderate-intensity, aerobic, physical activity, or 75-minutes of vigorous-intensity, aerobic, physical activity. To stave off boredom, it’s suggested to do a combination of both types of exercise throughout the week (American Heart Association, 2017). Aerobic physical activity is described as, “Exercise with oxygen.” During this type of exercise, the body, more specifically the heart, is working hard to pump oxygenated blood from the heart to the muscles throughout your body (another name for this type of exercise is cardio-exercise). Specific examples of aerobic exercise are; cardio machines, walking, jogging, running, swimming, hiking, and even dancing. The intensity of the exercise depends on how fast and how long the exercise is consistently maintained over a period of time (Weil, n.d.).

When someone who exercises a lot such as a person that does sports the pulse rate level rises much less than in a person that doesn’t exercise a lot or does sports. You can check your heart by taking the tips of your first two fingers to press gently over your blood vessels on your wrist count your pulse for 10 seconds and multiply by 6 to find your beats per minute. You want to stay between 50percent to 85 percent of your heart rate. That is how you check your pulse.

As with the previous two phases the athlete will undergo another series of assessments. This time however the assessments will be different. Whereas before we were looking at areas of explosive strength in sprinting and weighted exercises, this time the emphasis will be placed on cardiovascular endurance. The assessment we will be primarily focused on will be a 1.5 mile run for time and heart rate. The reason we are focused on heart rate is to find his optimal heart rate for prolonged distance. Using a heart monitor we will have him preform the test three time and average of the three heart rates will be the target number. He will of course be allowed a 10 beats per minute cushion to allow for factors that are beyond our control like atmospheric issues such as heat and humidity, and any delayed onset muscle soreness(fitnessschoolbook). Again once all the data has been analyzed we will begin the last phase of the training regime.

-Heart rate is the number of times a person 's heart beats per minute. When you are preforming a type of exercise that will increase your heart rate, then your heart will pump blood all around your body faster and especially to muscles that are working the most because they require the most oxygen because of the intensity they are working at. It is vital to take your resting heart rate and the normal heart rate is 60-100bpm. For example, our cardiovascular exercise was cycling on a stationary bike for 20 minutes at a reasonable pace and this will depend on whether your heart rate will increase at a slow, fast or steady rate. However, the first 5 minutes we cycled at a very fast pace in order for your heart to pump more blood all around the body and to the required muscles in order for them to work harder. But the response is that the heart rate levels off, which means that it becomes steady so that after beginning the exercise and you’re like 5 minutes into it then your heart rate will stay the same or increase by little bits unless you change the intensity all the time which is not required when doing cardiovascular exercises.

1 Begin with only light aerobic activity to increase your heart rate. You may bike, walk, or jog for up to 10 minutes. Do not jump, run, or lift weights.

INTRODUCTION: High-Intensity Interval Training (HIIT) is known as one method to treat Cardiovascular Diseases (CD), such as Coronary Arterial Disease (CAD) and Heart Failure (HF), due to its potential to improve cardio respiratory fitness (1, 15). This exercise format is characterized as aerobic exercise performed in a high intensity - usually controlled by either maximum oxygen uptake or maximum heart rate – with active and low intensity. Performing exercise in high intensities mixed with active rest allows patients to tolerate a higher effort before they become tired. Heart failure patients present a diminished exercise capacity, due to a smaller Ejection Fraction (EF), which tells us how well the heart pumps blood to body. To these patients, High-Intensity Interval Training has been reported for improving Systolic Function due to the increased effort in which the heart is working (16). The necessity to provide nutrients through circulation during exercise leads to an increased contractility and consequently LV Remodeling (15). Coronary Arterial Disease Patients have a decreased blood flow to the myocardial tissue due to an obstruction inside the coronary arteries. HIIT increases the arteriovenous O2 difference, which means there is an elevated consumption of oxygen by the tissues as result of a higher stroke volume. All those benefits have been shown in the literature, but most of the studies present data with short-term interventions. A few studies discuss the benefits

Physical fitness has two main classifications-performance related and health related. People have different performance related requirements in accordance with their occupation but all people have the same health related requirements (The World). Then there are two types of exercise that helps tone a person’s body while increasing its endurance. These are aerobic and anaerobic. Aerobic exercise is exercise that uses the muscles and bones. Cardio activities are a good example of this, such as running or biking. This type of exercise increases the strength of a person’s heart and boosts their lung capacity. Anaerobic exercise is an intense but short amount of exercise (Payment). Since it is only for a brief amount of time, it does not require the amount of oxygen aerobic exercise does. Instead it uses glycogen which comes from the sugar in a person’s blood. An example of this exercise is weight lifting or sprinting. A person’s requires both anaerobic and aerobic exercise for good health. Simply doing a cardio work out is not healthy, and for a person to see real results there must be some activity like weight lifting (“Anaerobic”).

The heart rate is a measurement of how many times the heart beats in a minute. Physically fit people tend to have a lower heart rate and during intense exercise tend to have lower rates as well. A decrease of heart rate at both rest and at fixed intensity of sub-maximal exercise [7] occurs a few months after an exercise program is begun. One’s heart rate reflects the amount of work the heart must do to meet an increase of demands of the body when engaged in activity. Heart Rate tends to increase proportionally with intensity oxygen uptake [16].

The muscles demand more energy and oxygen due to the increased workload that comes from exercise. This causes the heart rate and respiratory rate to increase in order to provide the required additional fuel to the muscles. In addition, the entire circulatory system works more efficiently due to vascular dilation and cholesterol reduction. By improving the condition of your cardiovascular fitness you are also helping yourself live longer, decrease the risk of heart disease, lower blood pressure, strengthen your cardiovascular system, and the list goes on. These reasons alone could save you from having heart disease.
