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 benefits of exercise are indisputable and understanding the relationship between cardiorespiratory endurance training and other categories of conditioning requires a review of changes that occur with incremented aerobic, or anaerobic capacity. Although, is moderation in thought of taking up endurance exercise for cardiovascular health. In order to provide an explanation, we would need to perform studies, include researched background information, and organization/analysis of the results. For instance, in the most sizably voluminous such study to date, involving more than 50,000 adults and presented at the 2012 annual meeting of the American College of Sports Medicine; participants who r...

- In 2014, the Centers for Disease Control and Prevention found that two of the top five causes of death in the United States were heart disease and stroke, which took almost 750,000 lives. These two leading killers in America can be preventable by a few different lifestyle changes, but one major component is physical activity. The American Heart Association recommends at least 150 minutes per week of moderate-intensity aerobic activity, or 75 minutes of vigorous aerobic activity, or a combination of the two....

- Effects of Endurance/Strength Training on the Human Body Exercise is a major key when it comes to living a healthy lifestyle. Although there are many different types of exercise as well as different types of intensity levels, depending on age, weight, gender, disease, etc., some types of exercise are better than others. Regardless of the type of workout, exercise helps control weight and certain health conditions and diseases. It also helps people be more positive and boost their energy. In the first study, it looks into the impact of extreme endurance workout on the heart.... [tags: Exercise, Physical exercise, Aerobic exercise]

- The Varoius Adaptations to Endurance and Strength Training Principles of training is a necessary instrument that should be applied to every sport and exercise in order that athletes and teams in training would have specific training objectives and goals to achieve. Without the principles of training, teams and athletes would be training blindly and this would lead to overtraining and burn out resulting in poor performances and therefore loss of interest and eventually result in the athlete dropping out of the training....

Endurance and Strength Training Effects on Physiological and Muscular Parameters during Prolonged Cycling
- Introduction: The research study my group and I examined was titled, “Endurance and Strength Training Effects on Physiological and Muscular Parameters during Prolonged Cycling.” This study done by Hausswirth et. all was published in 2010 in the Journal of Electromyography and Kinesiology. When performing in a triathlon, which consists of swimming, cycling, and running in a single continuous event, it is generally accepted throughout the exercise science community, that “over performing” during the cycling stage by increasing ones cadence or aerobic power, could hinder the running portion of the triathlon that follows (Hausswirth)....

- Every poem constructs a perception for every reader and most readers will have a different outcome from one another. In How To Be Drawn by Terrance Hayes, the author adds many hidden messages and symbols in the poems for the readers to uncover, and in many times it tends to be difficult. It takes a lot of examination to reveal what the speaker or author is trying to assert. Hayes’ uses many social and historical references such as racism into his poems to depict the anger within the speaker. One of the many themes that prevail in many of his poems is a sense of being trapped such as the poem, “Like Mercy”.... [tags: Endurance, Endurance training, Religion, Angel]

- Since the dawn of humankind, exercise has been a part of our existence, either consciously or unconsciously. Primal beings would run, climb trees, and sling weapons in order to survive and provide food, clothing, and other lifeline necessities for themselves and their families. As they continue to hunt on a daily basis, they unconsciously would build and maintain their cardiovascular system as they travel further to survive. Approximately 400 BC, the Hippocrates mention about exercise in great detail.... [tags: Health ]

- Many people have heard of low-oxygen training or high altitude training before, but probably do not know all that much about. This type of training to have an advantage in competitions is very well known amongst endurance athletes, specifically runners. Training in low-oxygen situation for short term will reap benefits for almost any athlete. Training at high altitudes is rewarding for athletes because it forces your body to make changes that will result in positive gains. While training at high altitudes the lack of oxygen causes your body to produce more red blood cells, these changes typically take around a month to occur and will last between 10 and 20 days (Dan Peterson, Live Science...
