Endurance Training Essay

These adaptations are relevant because the body is being stressed which leads to more blood being needed by the working muscles. With this increase in stroke volume and cardiac output, it also increases the heart rate. Heart rate is the amount of times the heart beats per minute. This means that the heart is working hard and being progressively overloaded increases the efficiency and will improve the performance of the athlete. Another adaptation is oxygen uptake. When the body is being progressively overloaded oxygen uptake is really important because it is the amount of oxygen being delivered to working muscles. This amount increases when exercise begins but decreases as adaptations occur. This is very similar to lung capacity as lung capacity is the amount of air that the lungs can hold. Another physiological adaptation in relation to progressive overload is haemoglobin levels. Haemoglobin is the substance in the blood that binds to oxygen and transports it around the body. These levels are important because it’s telling us how much oxygen and blood is being used and directly relates to stroke volume and oxygen uptake. Muscle hypertrophy is a term that refers to muscle growth together with an increase in the size of muscle cells. For a sprinter this adaptation is very important because it indicates that the muscles have been stimulated and grown and an

Cardiac output adapts throughout a training program. The "American Council on Exercise's Personal Trainer Manual" lists exercise adaptations as increased ventricle size, decreased exercise heart rate and increased stroke volume. Therefore, your heart can maintain a high cardiac output with less effort. Most improvement to cardiac output is contributed to increased stroke volume. Positive adaptations occur in as little as three months of aerobic training.

Choosing a vocation can be a daunting task. With the world ever-evolving, one may come across a new attractive career every year. In order to ensure optimal job satisfaction, it is vital to educate oneself about every alluring prospect prior to committing. Simple factors like the time commitment and salary can mean the difference between a content existence and a miserable one.

What limits the speed and stamina of most endurance athletes is the ability of their heart and lungs to deliver oxygen at a steady rate

Americans love their sports. People are constantly watching games like football, basketball, baseball, soccer, and volleyball live and on TV. There are many factors that go on during sports that keep them going. We all know about the coaches, players, fans, referees, and team owners, but on of the most important part is sometimes forgotten. That part happens to be athletic trainers. Athletic trainers make sure the athletes stay in good health and make sure that athletes recover from injuries so that they can return to the game. Athletic trainers also help prevent injuries from happening. Being an athletic trainer is a career path that involves many years of education and practice. Athletic trainers seem to go unnoticed at many sporting events, but in fact, have to go through tons of education and training and are a major part in health in sports.

During exercise there is an increase in cardiac output, which corresponds to an increase in maximal oxygen consumption. With the increase in oxygen consumption, a greater increase in blood flow occurs. This means there is more oxygen circulating in the blood for the tissues to take up. Due to the increase in blood flow, vasoconstriction of arterioles occurs to maintain mean arterial pressure (Bassett & Edward, 1997). This limits oxygen consumption because some of the blood flow is directed to the brain and skin. It is further pointed out that the heart is another limiting factor because it determines how much blood and oxygen are supplied to the muscles especially when blood flow exceeds maximal cardiac output (Bassett & Edward,

Millet, G., Jaouen, B., & Borrani, F. (2002, August 1). Effects of concurrent endurance and

During an exercise, changes occur in the oxygen and carbon dioxide level in the blood. The muscles cells start using up quickly oxygen in the blood as a result of the exercise making them to demand for more. More carbon dioxide are produced as a waste product from the respiring muscle cells which has to be taken away through expiration by breathing harder and faster.

Increased oxygen at the muscular level will decrease lactic acid build up. This lessens fatigue and, in turn, increases the amount of muscle you can build.

There are some grades of systematic inflammation process related to some pathological conditions such as cardiovascular disease and type 2 diabetes.

A person may be training as an athlete for a big competition or someone training for a marathon. They can even just be a young or old individual living a normal life, yet some people may think that athletes are more viable to do strength training than an average person. Although people may have assumptions that athletes are the only ones who use strength training, individuals use muscular strength and endurance in their daily life do to the many benefits there are to it.

Professional athletes are excellent role models. However, most people don't acknowledge their medical trainers action. Despite this a career as a medical trainer intrest me.

19th of august Goal: I seek to enhance endurance no later than 30 minutes. I will use interval training training. This training will prevent fatigue, this through regular training with short intervals. Thus enhancing endurance by preventing lactic acid build up. This works by expanding the body's capacity to transport and use oxygen in the skeletal muscle. Therefore regular resistance exercise will gradually lead to more endurance.

Muscular endurance is very important for people playing sports and who have to sustain an activity for long periods of time. Muscular endurance is determined by how well your slow twitch muscle fibers are developed. In case your wondering what slow twitch muscle fibers are, I will explain. There are generally two types of muscle fibers in your body, slow twitch and fast twitch. Slow twitch muscle fibers cannot exert as much force as fast twitch, but can sustain an effort over a much greater period of time. Fast twitch muscle fibers can exert a great amount of force but for a very limited amount of time. Therefore, slow twitch equals endurance, while fast twitch equals strength.

This is what causes us to be sore. The muscles then build back up, becoming stronger than before. (lifehacker.com) People still need to be careful when they exercise because they can hurt themselves or overexert themselves while doing it. Being a little sore for a 24-48 hour period is normal but when being sore is a severe pain, it was probably caused by overexertion. (lifehacker.com)
