Informative Speech On Exercise And Physiology

Our world is constantly changing because of new ideas, creations, and advancement in science. We learn something new every day, or at least majority of people do. If you really think about it, we have come a long from first seeing our own image from a reflection of the water to understanding why we look the way we do from genetics. Like one old coach told me, “you might fall behind, but the world keeps moving.” Exercise is something that has been talked about way before our time, but I will be writing about how exercise physiology has changed the world. The first thing I want to talk about is the positive and overall outcome of the growth of exercise physiology through science. Secondly, I will be discussing some of the negative effects including:
In the late 1900’s The National Athletic Trainers Association (NATA) was formed and a few years after, The American College of Sports Medicine (ACSM) was founded. The field of exercise educated people on how their bodies work. This was a very important concept because as people’s knowledge increased, more questions needed to be answered. Why is the percent of obese American children increasing? Why do my muscles cramp? What are training methods not working? These are all questions exercise science/physiology answer. As the Internet FAQ Archives website summarizes, “Exercise may also be directed to improvement of a person's general health, physical fitness, or as physical therapy, to augment an existing treatment to remedy or to ameliorate the effects of a disease or illness upon the body.” Exercise physiology shows that there is a correlation between the human body systems and athletic performance. Some of the systems that effect performance include the cardiovascular system, the cardiorespiratory system, the thermoregulatory system, body composition and the musculoskeletal system. Thanks to the growth of exercise physiology, we know that the body is fueled by substrates, muscles cramp occur when there’s not enough oxygen supply, and foods are loaded with sugars. This brings up my other topic about the negative changes through exercise
In our society, we see men with chiseled abs and abnormally sized muscles and think that they are in top-notch shape. In the other side, we look at models and see that their waist sizes are close to zero and believe that they are in good shape. We now know that the outside appearance doesn’t necessarily prove health. People attempting to reach their health goals can choose to take enhancing supplements that are not always legal. Let’s talk about the legal supplements first. Sports supplements including: protein, pre-workout, creatine kinase, etc., have become increasingly popular in the last decade. Although these supplements are not necessarily bad, if these supplements are used the wrong way it can lead to detrimental health. In article titled, Young body-builders beware: Supplements can be dangerous, experts discuss the risk of taking supplements rather than actual food. In a 2010 Consumer Reports investigation found that some protein shakes, if consumed frequently, could expose people to potentially toxic levels of arsenic, cadmium, and lead. The American Academy of Orthopedic Surgeons advised that children and adolescents shouldn’t take creatine supplements. Although, creatine has not been proven as “unsafe” higher amounts have been linked to kidney damage. Let’s take an account bodybuilders. Some of them have so little bod-fat that it
