Endurance plays a major role in many athletic activities. Without endurance training, many athletes would not be able to compete in their respective sports. Endurance training involves low resistance and high repetitions, but what exactly does this do to your body and how does it do it?
For starters, endurance training increases the level of certain aerobic enzymes, which are needed for the breakdown of fuels to produce energy. Enzymes are proteins that speed up metabolic reactions; they release and transfer energy. Enzymes are influenced by many factors:
1) Temperature- activity is increased when the muscles are warm, therefore warming up before the actual activity is very important
2) Acidity- lower Ph levels reduces enzyme activity, leading to fatigue
3) Fuel- enzymes work faster when they have more fuel
The faster the enzyme can breakdown your body's fuel, the faster you will receive energy.
Training also increases the number and size of the mitochondria. Mitochondria are cellular powerhouses that produce energy aerobically. All oxidative energy production takes place in the mitochondria. Oxygen is the key to endurance training, so the mitochondria are very important. Oxygen is needed to breakdown carbohydrates and fats, which provide energy. Dr. John Holloszy conducted an experiment to prove the importance of the mitochondria in endurance training. He had two groups of rats. One group was trained and eventually could exercise continually for four to eight hours. The untrained rats became tired after thirty minutes of exercise. Holloszy found a fifty to sixty percent increase in the mitochondrial protein and a twofold increase in oxygen consumption in the muscles of the trained rats. This...

... Endurance athletes have been found to have healthier mood state profiles. There are generally classified as having lower levels of tension, depression, anger, fatigue, and confusion. However, during periods of over-training, levels of anger, anxiety, and depression are increased. Overall though, endurance athletes are more mentally healthy than an average athlete is.
Endurance is gained by persistency with a lighter load. This means doing maybe one set of 20-40 with ten pounds, instead of two sets of ten to twelve with twenty pounds. You progressively increase your workload. Consistency is very important. Endurance workouts are all week long, all year-round.
Endurance training affects every part of your body, physically and emotionally. It makes you healthier and overall happier person. Endurance plays a major role in all of our athletic activities.
The data collected during this experiment has shown that a relationship likely exists between the rate of muscle fatigue and the time spent performing vigorous exercise prior to the set of repetitive movements. This is likely due to a build-up of lactic acid and lactate as a result of anaerobic respiration occurring to provide energy for the muscle cell’s movement. As the pH of the cell would have been lowered, the enzymes necessary in the reactions would likely not be working in their optimum pH range, slowing the respiration reactions and providing an explanation to why the average number of repetitions decreased as the prior amount of exercise increased.
The higher a person’s VO2max, the longer they can sustain endurance events at higher training intensities. Conclusively, the experiment proved that the trained participant had a higher VO2max (higher oxygen consumption) and was indeed more fit than that of the untrained participant.
Muscular endurance- As the player must continue running, their muscles will begin to tire and lactic acid will build up in their muscles. To ensure the players muscle don’t fatigue, the coach of this elite athlete has clearly targeted their muscular endurance. Shown through the multiple resistance trainings and circuit training, the athletes muscular endurance will be sure to improve.
“The purpose of this experiment is to compare the effects of a regime of maximal strength training in combination with a usual endurance training programme with an endurance only training programme on the physiological and muscular parameters during a 2-hr constant cycling test in well-trained triathletes.” Their hypothesis was that in a 5 week period of training, the changes in the cycling cadence would be lesser in the endurance and strength training group versus the endurance only training group.
Another kind of endurance is short term muscle endurance. This training helps athletes to cope with
...nd after intense physical activity, the body is able to maintain a balanced level of carbohydrate sources and perform better.
Evidence of lifting weights can be traced back to the origins of man. As far back as cave painting and scrolls, there exists evidence of weightlifting. Initially as an expression of strength, to competition and functional training, weightlifting has carved its path through the ages. It has taken on a new role in the modern world; athletic training. With an entirely new emphasis in sports on speed, strength, and flexibility; weightlifting is more popular than ever. Unfortunately, young athletes often do more harm than good by injuring themselves lifting. When these uneducated lifters try to jump right into a program, lifting more than they should, an injury is imminent. What is overlooked, is that when weightlifting is done correctly, it has a great potential to prevent injuries instead of cause them. Understanding how the body works, using proper technique on the appropriate lifts, and participating in regular physical activity can greatly reduce the risk of athletic injuries.
Cellular respiration is an important function for the body to obtain energy (Citovsky, Lecture 18). There are two types of cellular respiration; aerobic conditions and anaerobic conditions. Aerobic conditions are the cellular respiration occurred with oxygen while anaerobic conditions are cellular respiration occurred without oxygen. The most common cellular respiration is aerobic conditions where oxygen were supplied for phosphorylation (Campbell et al., pg 177). In human body, anaerobic conditions occurred when muscle cells are overworked and oxygen is depleted before it could be replenished (Citovsky, Lecture 19). This is a common phenomenon during exercise. The accumulation and production of lactic acid from anaerobic cellular respiration has been always a cause of muscle sore from intense exercise (Campbell et al., pg. 179).
Enzymes are types of proteins that work as a substance to help speed up a chemical reaction (Madar & Windelspecht, 104). There are three factors that help enzyme activity increase in speed. The three factors that speed up the activity of enzymes are concentration, an increase in temperature, and a preferred pH environment. Whether or not the reaction continues to move forward is not up to the enzyme, instead the reaction is dependent on a reaction’s free energy. These enzymatic reactions have reactants referred to as substrates. Enzymes do much more than create substrates; enzymes actually work with the substrate in a reaction (Madar &Windelspecht, 106). For reactions in a cell it is important that a specific enzyme is present during the process. For example, lactase must be able to collaborate with lactose in order to break it down (Madar & Windelspecht, 105).
In this paper I will be looking at an article called The Over Training Syndrome, which was written in 1994. I will be comparing the information in the article with the content from the week 6 Qualifying Sports Training lecture. This will be done by directly quoting the article, then the lecture and having a short discussion on the quoted point. The four areas of comparison will be; the definition of overtraining, the cause of overtraining, the effects of over training, and the recovery time from overtraining. The goal of this paper is to discuss the advancement in knowledge over the last twenty years in these four points on overtraining.
From that we then need to define muscular endurance, so muscular endurance is your ability to exert force against a load for a longer period of
Firstly, it is highly effective for prevention and treatment of many common diseases and longevity. Strength training can improve muscle strength and endurance, make it easier to do daily activities, slow disease that related declines in muscle strength, and provide stability to joints. Stability exercises may help reduce the risk of falls. Such as heart disease. Mayo Clinic Staff said a routine of regular cardio can improve heart health. Recent studies have shown that break training is often tolerated well in people with heart disease, and it can produce significant benefits, (2015). It also allows the system of organs within the body to work better, especially the organ systems associated with the breathing and heart. According to an article in the journal "Circulation" wrote by Patrick Dale, (2014). When everyone begins to exercise, blood is shunted to muscles from other areas of body, including their gut. The temperature of blood increases and the blood vessels near skin expand to promote total body cooling. It increases the density of bone in the body, and stimulates lung function makes the lungs
I believe that fitness has a greater impact on you mentally than it does physically. Fitness releases chemicals that cause you to feel better instantaneously, improving mood for 24 hours. Fitness makes you more confident and improves your self-esteem, key for ridding anxiety and depression. Fitness makes you set goals for yourself, motivating you to improve yourself everyday. It gives you a boost of energy after, making you feel like you can conquer the world, or to just do your homework.
As the topic above endurance runners have slower twitch muscles in the body. The anatomy build of an endurance runners differs from a sprinter. Scott Amato, (2013, September 27 explains long distance are typically tall. The article also explains that long distance runners have long arms. The long legs of a long distance runners helps with a making fewer steps while running. While these are the typical characteristics of a long distance runners, some runners are normal height but have long legs to be able to give them the advantage of long strides. Most long distance runners are really thin and have less muscle mass. However; there is a reason why long distance runners have less muscle mass. Less muscle mass helps the long distance runners run longer as well as allowing the runner to run fast during a race because runners are not held down with all that muscle mass. Most runners do not weigh a lot because long distance runners run burn a lot of calories while running, causing runners to gain no weight at all. Most long distance runners have high VO2 max, which leads to them running for long periods in time. While these are the characteristics for long distance runners, there are different characteristics for
Can’t stay fit if one doesn’t put forth any effort physical fitness requires physical exercise. But in everyday life one has to do some sort of physical exercise it varies from picking up boxes to walking up and down stairs all day. Physical fitness is a measure of the body’s ability to run at full capacity that measures on a personal level. It measures aerobic endurance, muscular strength, muscular endurance, body composition and also flexibility (Wilson). If one doesn’t exercise ones body doesn’t work at its full potential and exercise affects ones body in many different ways there are also many was to exercise (Wilson). How ones heart and lungs do there job also depends on aerobic endurance. Aerobic and anaerobic exercises can also help with ones muscular endurance (Wilson).
