Cardiovascular Training
Cardiovascular (CV) fitness or endurance is how efficient your body is at taking in oxygen and putting it to use. The cardiovascular system is comprised of the heart, blood, and blood vessels through which blood travels around the body. Aerobic exercise is a key element in CV training. Aerobic simply means “with oxygen”, this type of activity includes things such as swimming, dancing, walking, jogging and cycling (Bushman, 2011). Essentially aerobic activities are exercises where large muscles are moving in a rhythmic way for a sustainable period of time (“Active Adults”, 2015).
Benefits of CV Fitness
CV Fitness is an important element in overall health and wellbeing. Adults that are physically active are healthier than those who are inactive and are less likely to develop many chronic diseases. Those who follow the guidelines of frequency, intensity, time and type of CV fitness are at lower risk of premature death, coronary heart disease, stroke, type 2 diabetes and some mental illnesses (“Active Adults”, 2015). It is found that adults who exercise regularly have hearts that gradually adapt to the activity rates and the heart increases in strength and size thus improving CV health. Aerobic activity aids in clearing fatty deposits from the walls of some vessels, this slows down the process of atherosclerosis (Marieb et al., 2014). Atherosclerosis is basically an accumulation of fatty deposits in inner linings of some arteries which blocks blood flow
Cardiovascular disease is the number one killer in the United States, causing about 610,000 deaths yearly (Center for Disease Control and Prevention, 2015). Cardiovascular disease is defined as a group of disorders damaging the heart and blood vessels, usually involving the blockage of vessels, which in turn harm the heart (WHO, 2015). A 2011 American Heart Association statement predicted that without intervention, 40% of United States adults will have at least one form of Cardiovascular disease by 2030. A large portion of these deaths by cardiovascular disease is due to the sedentary population. To better prevent cardiovascular disease, the Physical Activity Guidelines for Americans Advisory Committee stated that adults should complete about 150 minutes of moderate intensity physical activity, or 75 minutes of vigorous intensity physical activity weekly (Barry, Blair, Church, Hooker, Sui, Warren, 2010). Research has shown that meeting these recommendations is linked with lower cardiovascular disease risk, as well as reduced risk of mortality. The Center for Disease Control and Prevention estimates that only about 20.3% of Americans meet these guidelines. These statistics show that the majority of the United States population does not get nearly the amount of physical activity they need. However, even though many people are not doing the recommended amount of physical activity, this may not mean that they are living a sedentary life. Living a sedentary lifestyle is
Introduction: In this experiment, cardiovascular fitness is being determined by measuring how long it takes for the test subjects' to return to their resting heart rate. Cardiovascular fitness is the ability to "transport and use oxygen while exercising" (Dale 2015). Cardiovascular fitness utilizes the "heart, lungs, muscles, and blood working together" while exercising (Dale 2015). It is also how well your body can last during moderate to high intensity cardio for long periods of time (Waehner 2016). The hypothesis is that people who exercise for three or more days will return to their resting heart rate much faster than people who only exercise for less than three days.
Exercise and physical activity deliver oxygen and nutrients to your tissues and help your cardiovascular system work more efficiently.
Cardiovascular and metabolic diseases are a growing problem around the world today. Not only do diseases such as diabetes and heart disease affect individuals and their lifestyles, they also affect the economy, politics, education and the professional work environment. 20-26% of individuals in the United States live with heart disease, and obesity and high blood pressure compose the greatest factors for developing this disease [20]. Studies have shown a direct correlation between the amount of sedentary time and cardiovascular and metabolic disease risk, regardless of baseline measurements [20]. Thus, increase in physical activity will decrease cardiometabolic risk factors [8]. Several studies indicate a positive correlation between physical activity and decreased cardiometabolic risk markers [2,4,11,16]. However, we now know that an individual who is getting the recommended physical activity per day can still have a large amount of sedentary time.
The highest leading cause of death for men and women within the United States is heart disease. The number of deaths for heart disease is 611,105; this is more than half of a million lives being claimed by heart disease. (Centers for Disease Control and Prevention, Leading Causes of Death). This disease tends to be preventable, even though it’s the highest cause of death. In order to prevent one self from having a heart disease, individuals should take the right precautions throughout their everyday lives to reduce the risk of contracting different types of heart diseases; one of the best ways to prevent heart diseases is to engage in exercise. Heart disease involves the blood vessels becoming narrow in the body, which causes restriction
Obesity rates have continued to raise over the years. In America 1 out of 3 adults were considered to be obese. Due to these statistics obesity has become a huge concern for our country. Factors that are related to obesity are heart diseases, health issues, diabetes, and hypertension. To not be another statistic we must have a healthy nutrition and have physical activities in our daily routines. Aerobics is a great way to start a healthy lifestyle. As said in myDr, "Regular aerobic exercise improves your cardiovascular fitness by increasing your capacity to use oxygen. It does this by increasing your heart’s capacity to send blood (and hence oxygen) to the muscles." Cardiovascular exercise is extremely important because reduces health problems, improved bone and muscle health, and controls your weight.
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.).
Cardiovascular exercise includes workouts and movements that are particularly brought about to increase your heart rate and blood circulation throughout the entire body.This includes activities such as swimming, biking, cycling, walking and, of course, running. When you are training cardio, you are improving your heart, a muscle, and its ability to effectively pump blood throughout your body.Ideally, a healthy heart is one that beats regularly
The objective of this report is to critically explain the physiological effects of exercise on the human respiratory system and cardiovascular system. To begin with, I will explain the two systems, their specific functions and how they inter-relate. I will then go on to analyse the effects of exercise on the two systems by looking at the way in which the body deals with an increased workload, and any health issues that may affect this.
This year in physical education, I ran a mile in 9:37. I reached the 50th percentile, which was 10:00, but I did not reach the presidential goal of 8:23. To improve my cardiovascular fitness, I will ride my bike, hike, and jog more. Currently, I walk my dog most days, but on weekends I will set aside more time to go for a jog or hike in a park to improve my cardiovascular fitness.
Good physical health is a vital part of the well-being of every person. A major component of our physical health is “Cardiovascular fitness”. Cardiovascular fitness is the ability of the heart and lungs to provide oxygen to the muscles for activity of an extended duration. If we have a good level of cardio-vascular fitness we are able to sustain activity for a reasonable period of time and not fatigue easily. This can give individuals a variety of health benefits and allow more regular and enjoyable activity to be participated in. This research report will examine my results of cardio-vascular fitness tests and weekly physical activity events, which
Physical activity has been proven to have phenomenal benefits on the human body and is an important part of a balanced lifestyle. Statistics have shown that regular exercise can prevent illness and lower one’s likelihood of being diagnosed with a series of diseases significantly. It has been ‘medically proven’ that regular exercise can reduce a subject’s chance of being diagnosed with coronary heart disease or stroke by 35%, type two diabetes by 50%, colon cancer by 50%, breast cancer by 20%, early death by 30%, osteoarthritis by 83% and a number of other life threatening illnesses. Regular exercise can improve a person’s overall wellbeing and immunity to common illnesses. During physical activity, a person’s heart rate can increase significantly and allow more oxygenated blood to be supplied to muscles. A person’s breathing rate can increase during exercise and supply more oxygen to the lungs. The increased blood flow during exercise allows the brain to function better. Exercise has many benefits to the human body and is a major factor of disease
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 benefits of physical exercise in humans far outweighs the harmful effects associated with exercise. A prescription of physical activity has been known to delay the onset or prevention of many chronic diseases. An improvement in heart function, lower blood pressure and improve functional capacity is noticed after just a few weeks of exercising. Physical activity will also result in an increase of lean muscle mass, promote weight maintenance, increased flexibility, and a generally stronger more fit individual. Conversely, exercise when preformed strenuously or obsessively can counteract such positive effects, bringing up some issues like oxidative stresses, injuries, and
