Essay On Exercise Induced Muscle Damage

The first time I realized I wanted to specialize in medicine was when my father took me to the fire station when I was around the age of fourteen. He began to show me images of different cases and trauma scenes they had participated in. Since then, I have constantly asked my dad questions about different calls and scenarios about patients he has rescued. By having a father in the medical field and continuing to take science and medical courses throughout high school, I began to learn more about medicine throughout the years. Deciding to partake in these courses further advanced my understanding in medicine. These courses helped it become clear to me that the medical field is something I continuously

Muscle contraction can be understood as the consequence of a process of transmission of action potentials from one neuron to another. A chemical called acetylcholine is the neurotransmitter released from the presynaptic neuron. As the postsynaptic cells on the muscle cell membrane receive the acetylcholine, the channels for the cations sodium and potassium are opened. These cations produce a net depolarization of the cell membrane and this electrical signal travels along the muscle fibers. Through the movement of calcium ions, the muscle action potential is taken into actual muscle contraction with the interaction of two types of proteins, actin and myosin.

Overtraining occurs because of an imbalance between a Physical load placed on an athlete and their coping capacity. One of the reasons why athletes may over train is because of their parents/coaches that can push them to sports and wanting them to be good. They want their child to earn a college scholarship and push them to their limits. Working harder and never taking a break, because "someone else is working around the clock to be the best", is the most warped and tired mentality that coaches and parents feed young people…The problem is a lack of education and knowledge of our own bodies. The reality is that only a select number of athletes earn scholarships every year. It is a mentality now that these athlete need to playing all year and

To maintain effectiveness of muscle and bone activity, the effects of on the musculoskeletal system are the greatest benefits a person can ask for.

In this assignment I will be reviewing the different effects of exercise on the body system including the acute and long term using the pre-exercise, exercise and post-exercise physiological data which I collected based on interval and continuous training method. I will also be including the advantages and disadvantages of these, also the participants’ strengths and areas where they can improve on.

Rationale, Significance and Hypothesis. An extrinsic factor, which exerts a dominant influence on skeletal muscle fiber phenotype, is the nervous system. Buller et al. (1960) elegantly demonstrated the plastic nature of skeletal muscle fibers in response to changes in innervation type. Later, Lφmo and Westgaard (Lφmo and Westgaard, 1974; Westgaard and Lφmo, 1988) demonstrated that depolarization of muscle with specific patterns and frequencies of electrical activity are sufficient to cause changes in mature muscle fiber phenotypes. However, how myofibrillar gene expression and structural organization is affected by the frequency of impulses during activity, the amount of activity over time, or other characteristics of patterned activity is essentially unknown. To answer these questions will require the isolation and study of subsets of muscle-specific proteins in relation to different electrical activation patterns in vivo, an issue that cannot be easily addressed in preparations currently used in the study of muscle development and maintenance. However, using novel in vivo approaches can, in part, circumvent this difficulty.

From a very early age sports are introduced upon both young boys and girls. Although it begins with sportsmanship and teamwork, it begins to evolve into new objectives when these young athletes enter high school. In fact, high school sports are vastly different. Your mind is trained to obliterate the opponent and win at all costs. This mentality can often lead many young athletes to turn to supplements to assist in muscle building. The most common supplement in use currently is Creatine. While athletic departments and sports nutrition stores claim that it is harmless, why do so many high school athletes end up with severe muscular and pulmonary damage? The answer has yet to be clearly

In this lab, the focus was to study muscular fitness. In muscular fitness, there are two main components of measurements that are being taken, which are muscular strength and muscular endurance. Muscular strength is an individual’s ability to exert their maximum force. To test muscular strength, there are multiple tests such as 1 RM , Static Handgrip Strength, and Back Strength Dynamometer test. Muscular endurance is an individual’s ability to sustain prolonged muscular contractions. Tests that reveal results about an individual’s muscular endurance would be tests such as YMCA Submaximal Bench Press, Push-Up, and Plank test. It is important to remember that there is no single test for endurance and strength that will tell an

Delayed-onset muscle soreness (DOMS) is muscle soreness secondary to exercise, characterized by increasing pain or discomfort during subsequent 24 -72 hours, and subsiding within few days (Elsevier 2009). This was often associated with athletes and coaches where they usually lead to detrimental to their performance and recovery after activities. Although its physiological mechanism has not yet determine, it may relate to primary mechanical damage that may happen to muscle cells during exercise. Because of its transient nature (peak soreness 24 to 72 hours and resolution of symptoms within 5 – 7 days) experimentally induced delayed-onset muscle is used as a model of myogenic pain to study the effects of different therapeutic modalities.

Nearly anyone who works out regularly has experienced sore muscles after exercise. Sometimes you will feel it later that night, or the next morning and in some cases, you may actually think you are out of the woods, only to wake up two days later with stiff, tender muscles that feel as tight as rubber bands. For some people, sore muscles are a reward after a hard workout. In fact, some people are not happy unless they are sore after their workout, while others could live without it. Either way, all of us have probably experienced muscle soreness at one time or another.

I learned how to use proper way to protect joints while palpating patients, repositioning or lifting. How to minimize joint compression to minimize injuring myself from while working.

Muscle injuries present very frequently in sports medicine and the current strategies to improve muscle healing are unsatisfactory, often leading to incomplete functional recovery due to the formation of fibrosis [1,2]. Various molecules and bioactive materials which promote muscle regeneration and angiogenesis, and block fibrosis have been identified, but a combination of factors (proangiogenic, anti-fibrotic) are often required for optimal muscle repair [1]. Platelet-rich-plasma (PRP) is an autologous whole blood derived bio-agent/biomaterial that is being investigated for use in soft tissue healing. Although its mechanism of action is still largely unknown, autologous PRP has been proposed empirically for the treatment of sports-related

Exercise is one of the most important factors in a persons’ life. Physical activity, or the lack of it, can result in a person having a healthy life or cause them to have diabetes. The benefits of exercise are countless. The positive health results, the improvement in attitude, even better academic performance are all factors which make not exercising inexcusable.

Typically you turn to those handy, but smelly, creams and sprays and pick up a bottle of painkillers. This may be necessary for serious injuries, but if it's just a case of an aching muscle (after a difficult workout or a rough sleep) then you can instead turn to a handy home remedy.

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
