The Benefits of Physical Exercise to the Human Body
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 compulsive exercise disorders.
The Cardiovascular response to exercise occurs quite quickly, during exercise oxygen is demanded in the muscles and the body uses more nutrients, metabolic process speed up, more wastes are created, and the body’s temperature increases. With intense exercise hydrogen ion concentrations increase within the muscles and blood this results in an increased pH [16]. A study back in 1976 was done by researchers Hidetaro Shibayama and Hiroshi Ebashi on the effects of long-term physical training of adult men. Shibayama and Ebashi took five healthy males and gave them a routine of a twenty-min treadmill at two-thirds their V02 max for three years, five days a week. After a short while (just twenty weeks) the subjects resting heart rate decreased by five beats a minute, an increase of red blood cell count was shown, and a decrease in average cholesterol levels. Improvement in ventilation efficiency became evident, oxygen intake slightly improved as well, and lactate produ...

Another weakness in the experimental design was that the reliability of the experiment was very low. As each test subject was only tested against each amount of prior exercise once, the impact of random errors is likely very large, which can be seen by the spread of the data on the graph. Although, this was attempted to be rectified by averaging the results of all four test subjects, it does not improve reliability too much. Conclusion: The results of this investigation indicated that a relationship between the amount of prior exercise and muscle fatigue does exist, however the results are also not conclusive enough to speculate on what the relationship is. This means that the hypothesis “If the amount of time spent performing vigorous exercise prior to the set of repetitions increases, then the physical performance (number of repetitions) will decrease” cannot be supported or rejected due to the inconclusive data.
Submaximal and maximal exercise testing are two analytic methods that can be used to examine the cardiovascular, and cardiorespiratory fitness/health levels of the individual being examined. Submaximal testing is usually preferred over maximal mainly because the submaximal exam is more practical in a fitness/health environment. Both test require the individual being examined to perform controlled exercise on a(n) treadmill/ergometer until either steady state has consecutively been reached (submax), or the individual reaches their max (close to it). Being that both test are set to exceed time limits of more than 3 minutes we examine the use of the ATP-PC, Glycolytic, and Oxidative energy systems. Although a huge portion of the test involves the use of the oxidative energy system, we must remember that the three systems are co-occurrent.
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.

...l., 1987). In a study in which the participants performed sprint interval training (Bayati, 2011), there was an increase in maximal blood lactate from pre to post training, indicating greater capacity of anaerobic glycolysis. This increase was found coinciding with increased peak power, mean power, and total work . Sharp et al. (1986) reported an increase in blood lactate concentrations and total work performed during a 45-s maximal cycle sprint after eight
According to the CDC, Centers for Disease Control and Prevention, adults should do at least 150 minutes a week of moderate-intensity exercise, or 75 minutes week of intense aerobic activity. Everyone should try to do at least the recommended amount of weekly exercise. Not exercising can be detrimental to one’s health. Exercising moderately for at least 150 minutes a week or working out intensely for 75 minutes can add, on average, 3.4 years to one’s lifespan, while people who do not exercise have the highest premature death rate. Being active has both mental and physical benefits, adding exercise to your routine can create a happier, healthier lifestyle. Exercise, no matter how strenuous or simple, is an important activity for all people.

Endurance running is a rewarding experience that puts to test an athlete’s courage, perseverance and determination. It is a marvelous wonder how the human body, with the proper conditioning and mental focus, could achieve such tasking running distance. Elite runners complete the marathon course in just over 2 hours, while the average runner completes it in about 4.5 hours. It’s difficult to comprehend how someone could run, consistently, for 4.5 hours.The actual marathon is simply a formality as the journey starts the day training begins. The outcome, the day of the marathon, is dependent on how successful the training program was executed. Long distance runners are the biggest advocates of the sport, always convincing others to jump on the training wagon. However, some runners, while they refuse to admit it, ponder if the effects of long distance running could be doing more damage than good. It is true that long distance running is potentially dangerous to the heart; however, research suggests that physician examination, as well as proper mechanics and posture during the training phase would ensure an enjoyable journey towards reaching an endurance goal injury free and would even benefit the heart in the long run.

Steady amounts of exercise help manage the fat to muscle ratio of the body. Exercise attracts attention because of its ability to maintain a person’s weight. The simple act of walking burns calories, contributing to overall weight loss. For fitness fanatics, consistent, and more intense, exercise builds muscle. When muscles are not worked out they weaken, and the chances of injury elevates. However if muscles are overused, they become fatigued, and the risk of strains rise. Long term cardio exercise induces long term benefits. Studies have shown, with regular exercise, comes an increase in metabolism. Since exercise improves overall fitness, it helps boost the immune system. Nonetheless don’t overdo it, too much exercise without enough rest can promote colds. Keeping a consistent
“The main concept is that exercise (a term we will use generically to cover both exercise training and physical activity) does more than change traditional ‘risk factors’ (blood lipids, hypertension, diabetes, etc.; Mora et al. 2007; Green et al. 2008). In this context, there is a ‘risk factor gap’, and exercise appears to be far more productive than it should be based on changes in traditional risk factors alone.”
One of the best ways in how people can improve their overall mood, keep their bones healthy and even live longer, is by being an active person. Fred DeVito stated that “if it doesn’t challenge you, it doesn 't change you”; however most people just want exercise just to have a fit body and be healthier without knowing great results. Other effects that exercise has into the body are normalization of glucose, insulin and leptin levels. In other words not only will it make the appearance in a person’s life to look great, but their entire body will have an extraordinary response. In order to have a more fulfilling and enjoyable life, those who are out of shape should participate in regular fitness schedule reginert.
Adding exercises into one’s daily routines can change their whole lifestyle. Many people look at exercise as being something just for people who want to lose weight or to become muscle bound, but there are a great deal of benefits that can be received from exercising regularly. Of course gaining muscle and losing fat are the two most popular reasons that usually attract people to the gym, but they make up a small part of the potential benefits that can be achieved with exercise. There are several ways in which I have benefited in my life from exercising regularly, besides just making me bigger and stronger. It has made me become more organized, helped me make better decisions, and motivated me to take on new challenges in life.
The benefit of physical fitness is to prevent obesity and encourage a healthy lifestyle thru training and focusing on the body’s compositions. Physical fitness is the measure of the body’s ability to go full capacity. If one doesn’t exercise ones body doesn’t work at its full potential all the time. Exercise can lower the risk of having major problems with ones body and relieve stress.
