Creatine and its Dangers
Creatine is a very controversial supplement on the market today. Many endorse the uses of creatine, but others are skeptical about the advantage a person receives from taking it and the dangers one inherits as a result of creatine consumption. The debate remains due to the short amount of time that creatine has been available. People base their opinions on preliminary studies that have been done but no one knows the long-term effects of creatine on the body. Many take the risk without vast knowledge, but others still remain skeptical based on preliminary evidence that discourages the intake of creatine.
How Creatine Works
Creatine is naturally produced in the body in the liver, pancreas, and kidneys. It can also be provided to the body through the consumption of fish and meat. (http://www.mothernature.com/ency/supp/creatine_monohydrate.asp) Creatine aids in the process of ATP which is energy used for quick, explosive activities such as the sports listed above. When ATP levels drop, muscles become fatigued. “Regeneration of ATP is essential if fatigue is to be delayed,” according to Charles P. Bolotte, MD. (http://www.lsms.org/journal/98creat.html) In theory, taking more creatine supplements allows for more creatine to be available to synthesize more ATP and therefore causes less fatigue in muscles. ATP is readily available energy for the body that is used in everyday activity. The synthesis of ATP is needed for all activities in the daily lives of people. It is used in the transmission of nerve signals, the movement of muscles, the synthesis of proteins, and cell division. Energy is released when one of the bonds between the end phosphate group is broken and the molecule becomes...

Creatine is one of the most popular sports supplements on the market and is used by bodybuilders, and athletes. It is an amino acid, like the building blocks that makes up proteins. It is also an important store of energy in muscle cells. Creatine is a natural nutrient found in our bodies and in the bodies of most animals. It can also be found in the form of a powder and sold as a supplement. Creatine is categorized as a food supplement by the Food and Drug Administration, like a vitamin and is available over the counter at drug stores and nutrition centers. Approximately 95% of the body’s creatine supply is found in the skeletal muscles. The remaining 5% of creatine is scattered throughout the rest of the body, with the highest concentration in the heart, brain, and testes. The human body gets most of the creatine it needs from food or dietary supplements.

Creatine was not a vitamin, however, but a synthesized blend of certain amino acids, which are the building blocks of proteins. The benefit creatine provides is increased energy for quick, anaerobic bursts of activity, such as are required in weightlifting. Athletes taking creatine can do more repetitions and sets of exercises than they could without it. Essentially, it speeds up the process of adding strength and size to the muscles by intensifying the workout. It has been compared to the way a marathon runner might saturate his muscles with carbohydrates before a race to provide endurance except that creatine strictly helps in anaerobic activities like muscle contractions.

Controversy has surrounded creatine every since it has hit the shelves. Creatine is already produced by our bodies in the liver and kidneys. However, a frequently asked question is: why do we need to take more? The purpose of creatine is to add water weight. When taking the supplement it takes away the water absorbed by our muscles which makes us have to drink even more water. However, when an individual is taking creatine it has to be regulated properly. If too much of the supplement is taken more harm can be done than good. According to Stuart Young, an individual needs to drink a bare minimum of a gallon of water per day to avoid adding harm to our bodies. Young also mentions how too much

In the article Should Colleges Really Eliminate the College Lecture? by Christine Gross-Loh, Loh discusses the relevance of traditional college lectures and how it could become obsolete in the near future. She explains how a “flipped classroom” could be more beneficial in terms of academics and show improvements in students learning abilities.

Creatine has been used in sports throughout time. Athletes have always had a fascination with being excellent at what they do. With the banning of steroids from competitive sports and the implementation of random drug testing in most sports, most athletes are still somehow hoping to gain an edge on their competition. This edge that they are using is creatine.
In the end, “The Yellow Wallpaper” examines the relationship between a loss of freedom and insanity. Specifically, the story uses John’s treatment of the narrator and the narrator’s subsequent reactions to demonstrate the evil that can occur when people deny others their freedom. John adds to this theme by exercising complete authority over the narrator’s life, thereby causing her descent into madness.
The use of steroids and performance enhancing drugs is a common trend that is currently fascinating athletes all over the world. Athletes who are using these drugs are damaging the sport and harming their bodies at the same time. Seeking a greater athletic physique and ability, athletes turned to the use of steroids. Once the dangers and possible health risks arose, athletes then turned to performance enhancers. Two specific supplements have taken the sports world by storm and now are being used by athletes of all ages. They are androstenedione and creatine. It took years until people began to understand how dangerous steroids really were. These performance enhancers, like androstenedione and creatine are going to produce the same results.
The idea of a flipped classroom originally came about in the 1980s when Eric Mazur developed a computer-based instruction to guide students through the lessons outside of his class. He did this because he felt his students needed him most during the class time (Schultz, 2014). Through time the idea of the flipped classroom has continued to be expanded on. In 2000, Lage, Platt, and Treglia published a study titled “Inverting the Classroom: A Gateway to Creating an Inclusive Learning Environment.” This study stated that different learning styles are no longer limited by time constraints or the possible loss of content. According to Lage, Platt, and Treglia, “Inverting the classroom means that events that have traditionally taken place inside the classroom now take place outside the classroom” (Lage, Platt, & Treglia, 2000, p. 32). Lage, Platt, and Treglia wanted to reach students with different learning styles by providing options for the students to use in learning outside of class and to increase their interaction with the students and teacher inside of class
There are three main energy systems used in a game of touch football which consist of the creatine phosphate (ATP PC) system, lactic acid system and the aerobic system. Each system plays a vital role during game play. Every muscle in your body requires energy to perform all movements, and to do this, the energy is produced by the breakdown of a molecule called adenosine triphosphate (ATP). ATP is found in all cells which is a chemical form of muscular activity and performs mostly all functions in the human body. It contains 3 phosphate groups and adenosine. ATP is stored in the muscles and lasts for approximately 10-30 seconds. Carbohydrates, fats and proteins, are all producers of ATP from the food we eat; however Creatine Phosphate is also a high energy compound producer found in the cells. These three chemical reactions are conducted to continue muscular work. The first system used in a game of touch football is the ATP PC system. This system is stored into the muscles and used in short durations for up to 10 seconds and doesn’t not require oxygen therefore being anaerobic. ATP lasts approximately 3 seconds, and then Creatine phosphate (CP) will continue until all ATP PC energy is used up. The use of ATP is high intensity and would usually be used in a 50m sprint or a pass in touch. Once the CP energy is used up the body then switches to the lactic acid system. This is because of the breakdown of glucose, resulting in the production of lactic acid. The lactic acid system an anaerobic energy system, which lasts for approximately 30 seconds to 2 minutes, and is the conversion of glycogen to glucose. In relation to a game of touch football, the lactic acid system could be used during a quick wruck, as the movements required are a...
