Slow twitch are characterized by having long contraction rates, being resistant to fatigue, relying on oxygen as their main source of metabolism, and are used primarily in endurance type of activities that don't require a great deal of force. Fast twitch fibers on the other hand have short but powerful contraction rates, are highly fatigable due to their reliance on anaerobic metabolism that produces lactic acid, and are more suited to activities that are powerful and quick in duration. So the next time you are watching or participating in an athletic event, try and think of what type of muscle cells are involved and see if you can pick out which athletes have a predominance of that muscle type in their

Justin Atkinson November 27, 2012 Why Athletes Should be Drug Tested Sports are a big part of the world. Many people idolize athletes. What people don’t think about is how the athletes are when they are not around a whole bunch of people. Have you ever wondered if your idol did drugs, such as steroids, marijuana, or non-prescribed cortisone, etc. Many people do not think about these things.
In recent times the drugs have become more sophisticated and are made to target a wide range of sporting activities. Anabolic steroids or Testosterone for instance is mainly used in power sports like sprinting, weight lifting and cycling as it helps build increased muscle mass and strength, or in smaller doses can help with muscle recovery. Anabolic steroids were banned from sporting in 1975 after a test was developed to detect there use. Then in 1983 caffeine was also banned this was followed by testosterone, blood doping and Erythropoietin (EPO), although accurate tests for their detection was not found until 2000. ( USADA CEO Travis Tygart 2012) Said, ‘Nobody wins when an athlete decides to cheat with dangerous performance enhancing drugs, but clean athletes at every level expect those of us here on their behalf, to pursue the truth to ensure the win-at-all-cost culture does not permanently overtake fair, honest competition.
This work presents people with, in the reviewers opinion, qualitive data and personal observation. The qualitive data is represented by the select amount of athletes and coaches they interviewed and the personal observation was done by the coaches and athletes. Given that, it is possible that the work also included secondary material since the authors haven’t experienced any of what the coaches and athletes are talking about. The reviewer thinks that this article could demonstrate a thesis and also argue it because of the history that Compton has as a gang-run town and the evidence given to the authors by the athletes and others and how they are learning to succeed despite what they are faced with. Like one of the athletes interviewed stated (Beaver), “It’s easy to be like everyone else, being different is hard” (p.88).
Walking is greatly underestimated as a form of physical activity. Frankly and concisely, walking is a very potent form of exercise. And exercise is a must for Type 2 diabetics needing to lower their blood sugar, lose weight and keep it off. Whether walking is the best method of exercise is up for debate: running for instance will always burn more calories than walking will. But, running is also not for everyone.
Depporah Joseph M B English 042 10 May 2012 Anabolic steroids Should athletes be allowed to use performance-enhancing drugs in order to improve their performance? Steroid usage in sports has long been a big issue for many athletes both professional and amateur. Steroids are not condoned in any sport however; some athletes do take the chance by using performance-enhancing drugs in order to increase the chances of a successful outcome in a competition. Many athletes have been barred from participating in certain sports because they were convicted of taking steroids. In light of this, one can only wonder how many top athletes have won events due to the use of steroids.
Therefore, many athletes are willing to risk it all by taking performance enhancing drugs to be the best in their profession mainly for three reasons: the pressure to perform, the life style, and the desire to be the best. Athletes have to deal with pressure to perform by their coaches, owners, and by others playing his or her position. Coaches want the athletes to do well because more Johnson 2 than likely if the athletes do well, the team will win. Coaches are under more pressure to win than players because their jobs depend on winning games. If the players don’t perform well; coaches will look at other players to help the team win.
They have coaches that push them to their limit and encourage them to do well the same as a football or hockey coach. Dancers are often looked at as a group of people who perform but they compete against other teams. Just because their competitions involve a stage and judges, does not make them any less of a sports team. Movies and stereotypes often portray dancers as dainty and weak but this is not true. Endurance, physical strength and flexibility are required to become a dancer.
Shelby Karpman, a physician who has been involved in numerous MMA events during the past 20 years. Sekeres starts the article by quoting Karpman as saying a “ban would only drive the sport underground, and lead to increased health risks” and banning the competitions “will only generate more injuries and deaths” (Sekeres, S2). Dr. Karpman states in the article that he “has worked in all those sports [boxing, hockey and football], and said the injuries he has witnessed in MMA, and the latest research, do not justify a medically-endorsed ban”. Dr. Karpman has experience in medically supervising over 200 matches and watching more than 2,000 fights. “The Ultimate Fighting Championship held its first Vancouver event in June, and a nearby hospital treated broken limbs, cuts and severe bruises, but not brain injuries.
