A Review: Genetics as a Predictor for Success for Elite Athletes Performing in Power vs. Endurance Sports

Common wisdom tells us that a sprinter is highly unlikely to excel in a marathon, and vice versa. It is easy to conceive that genetic variation is a major source of such differences in athletic ability. Actually identifying these genetic causes requires classification of athletic traits and in depth data analysis. Every year the number of polymorphisms that are candidates to clarify individual variations in sports performance increases. The growth of complexity and disproportion between studies parallels with advances in sports genetics. Additionally, there are numerous factors that play a part in these studies of elite athletes. These factors include gender, size of population, ethnic origin or level of competition of candidates, and the statistical approaches all make correlations between studies difficult. Recent studies support the possibility of developing polygenic profiles that could be used as a method to determine an athlete’s genetic predisposition to certain sports and events. A recent study conducted by Buxens et al., investigated the correlation between genetic polymorphisms and world-class endurance vs power athletes. Their research was published in an academic journal and was titled; “Can we predict top-level sports performance in power vs endurance events? A genetic approach”. The goal of their study was to discriminate potential genetic differences between athletes who are in both endpoints of the sports performance continuum, that being endurance vs. power (Buxens et al.). In this experiment, the population studied consisted of one hundred males aging 20 to 39 who competed within the last 10 years at an exceptionally high level. Of the one hundred males, fifty were world-class endurance runners who were European champions and Olympic…...

Student Athletes Article Review

... A Conceptual Model of Academic Success for Student-Athletes Summary Student-athletes are a nontraditional group burdened with many demands and expectations. Collegiate sports are a popular mass commercial form of entertainment and generate millions of dollars. NCAA Division 1 sports generated 751 million dollars in revenue this year at the expense of student-athletes’ academic goals. Graduation rates for athletes are lower than traditional groups. Support services have not consistently or effectively enhanced learning and personal development of student-athletes. Analysis Athletes spend 40 hours a week on sport related activities decreasing time for academic pursuits and productive activities. This time is spent with other athletes and coaching staff which impairs personal development and social integration. The rigorous schedule leads to physical exhaustion and nagging injuries. This hampers attention to educational pursuits and goal attainment. Educational Importance Colleges and universities have a duty to provide the best educational experience possible for its students. Education should not take a backseat to sports on campuses across the country. Individual, multilevel, and culturally relevant curriculum and programs should be developed to promote personal, social, and academic success for student-athletes. These programs need to ensure that athletes can compete not just in sports but in life. Reference Comeaux, E. & Harrison, K. (2011). A......

Genetic Testing & College Athletes

...Genetic Testing and College Athletes On April 13, 2010, the NCAA made tests for Sickle Cell Trait (SCT) mandatory, effective in August 2010. SCT is a condition where the blood cells are elongated and potentially block blood flow and resist bonding to oxygen. The trait is generally benign but becomes active under extreme physical stress. For athletes, when performing strenuous activities, the trait is sometimes triggered and can potentially cause death. The statute states “student-athletes must be tested for sickle cell trait, show proof of a prior test or sign a waiver releasing an institution from liability if they decline to be tested.”(Brutlag, 2010) SCT genetic testing and NCAA regulations were implemented in order to protect student athletes, but the testing raises questions of who should receive the test results, the use of the results in discrimination against affected athletes and its potential to be cascade towards excessive genetic testing. In the current legislation, the results from an athletes test are given to the school, the coach and the athlete. This disclosure policy has the potential to be used to discriminate against those who are afflicted with SCT. Although the athlete has the option to opt out of testing initially once they have the test, the disclosure to the school and coaching staff is automatic. The test results should be first given to the student, and then they should have the option to waive liability and not disclose to the......

Nutrition Knowledge and Attitudes Among Clemson University Student-Athletes

...NUTRITION KNOWLEDGE AND ATTITUDES AMONG CLEMSON UNIVERSITY STUDENT-ATHLETES A Thesis Presented to the Graduate School of Clemson University In Partial Fulfillment of the Requirements for the Degree Master of Science Nutrition by Ashley Nicole Dunnigan May 2010 Accepted by: Beth Kunkel, Committee Chair Gail Delicio Karen Kemper i ABSTRACT Participants in this study were 95 Clemson University student-athletes who were currently on the varsity men’s and women’s soccer, tennis, track and field, and swimming and diving who completed a survey on nutrition knowledge and attitudes. The mean total point score on the survey was 17.48 + 1.71. The mean score on knowledge questions on the survey was 11.59 + 3.14 or 46.3%. Females had a slightly higher mean score (12.3+ 3.03 or 49.2%) than males (10.9 + 3.13 or 43.6%) on the knowledge questions. The mean score on attitude questions was 5.89+ 1.67 or 58.9%. Females had a slightly higher mean score (6.19 + 1.53 or 61.9%) than the males (5.60 + 1.76 or 56%) on the attitude questions. A multiple regression analysis for impact of sport, gender, class rank, previous nutrition course, and eating situation on total score on the survey gave an overall R2 of 0.174 (F= 3.75, p= 0.004). There was no significant unique effect of class rank (p = 0.084), sport (p= 0.079), and eating situation (p= 0.079) for this model. The unique effect of gender (p= 0.003) and taking a nutrition course (p= 0.036) were statistically significant. Even......

Genetic Testing

...480 Article April 1, 2013 Genetic testing for sports is not something that is very common. Some people think that it is needed so that any type of athlete can do well in their preferred sport/skills. On the other hand, the disadvantage could be that sports may not just be for fun anymore. According to Bill Miller, genetic testing will change sports in a way that each individual will be able to maximize their performance in certain areas and minimize their risk for any sort of problems. Even though they say that they can alter these genes, does it really work? Eventually, according to the Washington Post, the Food and Drug Administration had to get involved because they never cleared this kind of testing. Atlas Sports Genetics, out of Boulder Colorado, was the first company to offer Athletic DNA testing in the United States. They decided to test a specific gene, which controls muscle protein, ACTN3. This protein helps the muscles create quicker spurs of energy and power in the body. According to Atlas’s president of operations, “A lot of people get confused and think we’re saying this can tell you whether you or your child will be the next Michael Jordan”. He also stated, “It doesn’t tell you that. But it will tell you whether you are producing this protein and whether you are predisposed to be good at a sprint sport or an endurance sport.” He is saying that if a person does develop this protein well they should be focusing more on sports that have a greater amount......

Salaries of Sports Athletes

...Salaries of Sports Athletes The world of sports is a multimillion dollar industry. Around the globe, people flock to sporting events or watch their favourite teams faithfully each week on television. As a result, professional sports athletes receive huge salaries – well above, for example, those of doctors, lawyers, teachers or social workers. There is some debate about whether such outrageously high salaries are justified. On the one hand, sport is viewed as a professional career, in which the top players should rightly earn high salaries. Athletes train rigorously from an early age to become peak performers in their field. They face tremendous pressure in each and every game, match or competition. Their personal lives are compromised and they lose all privacy. At the same time, their strong achievements bring honour and attention, not only to themselves, but also to their teams, schools, cities or countries. On the other hand, various professions contribute to making our world run smoothly. Doctors put in at least ten years of grueling study and internship; their work saves lives. Teachers educate and inspire young people to be responsible citizens: their efforts produce the citizens of tomorrow. Social workers rescue individuals facing physical, mental and psychological challenges: their intervention creates safer societies. Yet, professionals in the fields above usually struggle to get by, despite their meaningful and critical contribution to the world. In my view,......

The Power of Steroids in the Sports World

...the human race. These drugs are seemingly notorious for their ability to produce large amounts of muscle mass in an attempt to exploit ultimate power, performance, and dominance in a person. However, the negative effects of steroids tend to have a severe impact on the justification of the drug’s use in today’s society. When I say society, I am rather referring to a more predominant superior subculture, the professional athlete that can easily be held accountable for the cultivation and spread of steroids. This “high-class” group can denote the contrary of ethics; that is, revealing actions which tend to expose a sense of narcissistic personal qualities that hinder our beliefs of what is right and what is wrong. At one point or another, performance enhancing substances outspokenly seem to enter every professional athlete’s mind. The issue of steroids or any performance enhancing drugs in this matter has significantly heightened recently and seems to be a legitimate issue within professional sports. In an attempt to meet expectations and standards, reduce the pressures to perform, and alleviate public scrutiny, many professional athletes are left quivering in fear whether or not to take the two-faced drug that’s so readily adhered to by many. In my attempt to explore the mainstream issue of steroids in professional sports, I wish to focus on three imperative aspects that will help assist in the configuration of such a prevailing concern. How do steroids operate......

Drugs in Sport

...for athletes to take performance enhancing drugs despite the risks involved? Abstract Drugs in sport is an ongoing problem which I believe will never be completely abolished from the sporting world. We have definitely come a long way since the early days of drug use with the introduction of governing bodies such ad WADA to help control the testing of athletes and the detection of illegal substances, however I do not think we will be able to completely remove this ’drug culture’ from the sporting world. Therefore having experienced first-hand the drug testing practices involved in detection after competing in the world youth championships this year I was interested to look into the motivation behind athletes who choose to cheat and risk their future career both athletically and their career after retirement having been branded as a 'cheat’ within their sport. I will do this by looking into the history of drug use in sport and the enhancements the drugs provide to performance to try to understand why athletes risk their careers to simply win.

Amateurs vs. Athletes

...10 March 2014 Amateurs or Professionals? Big-money college sports takes your breath away. College football and men’s basketball have become such huge commercial enterprises that together they generate more than $6 billion in annual revenue, more than the National Basketball Association. A top college coach can make as much or more than a professional coach. Powerful conferences like the S.E.C. and the Pac 12 have signed lucrative TV deals, while the Big 10 and the University of Texas have created their own sports networks. Last year, Turner Broadcasting and CBS signed a 14-year, $10.8 billion deal for the television rights to the NCAA’s men’s basketball national championship tournament (a.k.a “March Madness”). And what does the labor force that makes it possible for coaches to earn millions, and causes marketers to spend billions, get? Nothing. The workers are supposed to be content with a scholarship that does not even cover the full cost of attending college. Any student athlete who accepts an unapproved, free hamburger from a coach, or even a fan, is in violation of NCAA rules. Nevertheless, the NCAA prohibits any form of payments, beyond scholarships, to any athlete who is responsible for producing the revenue. The NCAA also restricts the ability for any college athlete to earn income from an outside source. In a study sponsored by the NCAA, they discovered that college players have less money than non-athletic students, and almost fifty-eight percent are not even......

Athletes vs. Non-Athletes

...Athletes vs. Non-Athletes A sport is an activity involving physical exertion and skill in which an individual or team competes against another or others. Many high school students across the U.S. participate in some kind of organized sports team. Is it morally right to let kids play sports and encourage them to become student-athletes? Many people believe that athletics can make a person change their personality, or it takes too much time away from them performing to their maximum strength, academics. Some even question, what the purpose of playing a sport? The purpose of this essay is to explain why it is morally justifiable for parents to let their kids be engaged and play sports. Playing sports can help you become a better person for the future and can help students become motivated about academics. I will explain how a student-athlete builds character and the aspects that they learn on and off the field. Being a student-athlete does not only mean you only know how to play a sport or sports but you know how to compose yourself around others, and how playing a sport in high school can help you become a better person in the long run. Participating in team sports helps to develop good character. One of the major characters you learn by participating in athletics is that you learn how to become responsible. Being a student-athlete you must know your priority, and that is that you are a student first, then an athlete. There are many things you must know to being eligible......

Research on Challenges Facing Sport in the Country Still Doing Litereature Review.

...Richard Attias Become a fan Email The Development Factor: The Challenge of Sport in the 21st Century Posted: 10/21/2014 8:39 am EDT Updated: 10/29/2014 9:59 Sport occupies a peculiar place in world dynamics in that it surpasses the limitations of geographical boundaries and social classes. Still, a gap remains between developed and developing nations when it comes to sport. In the industrialized world, sport as an economic sector represents approximately 2% of GDP. For developing economies, though, the challenge remains making sport a factor of economic development, and a driver for social change, so it benefits all citizens in the long term. UNESCO's 1978 International Charter of Physical Education and Sport classified sport as "a fundamental right for all." But the low place sport occupies in the developing world's priorities shows that its importance as an educational and social tool is not yet universal. Everyone agrees that sport contributes to economic development by creating jobs and stimulating business activity. The organization of a major sporting event, for example, is a great opportunity for the local economy. The thousands of people who attend will spend money on food, lodging, transportation and other, related tourist activities. However, in recent years, we see these economic benefits are obvious only the short term. If we take the example of South Africa in 2010, the positive impact of the World Cup was, in terms of job creation and reduced......

The Power Elite Does It Exist Today

...C. Wright Mills proposed the power-elite theory in 1956, which states that there is a power elite in modern societies, an elite who commands the resources of vast bureaucratic organizations that have come to dominate industrial societies. According to Mills, the power elite are the key people in the three major institutions of modern society- military, economy and the government (Mills 1956). It is the elite that occupy these leadership positions within the bureaucracies. Although this theory was proposed in what may have been a simpler time, the structure of power in America remains very much the same, as does the close relationship between the military, corporate, and government elites. Mills placed the military as one of the triumvirate groups that comprised the power elite. The military has been elevated to a position of prestige and power and the present class of professional soldiers has had an impact that is far greater than just military affairs. In World War II, large corporations tied to the defense industry rose in power and influence and formed the origins of what President Eisenhower called the military industrial complex (Swanson). The war brought a bureaucratic centralization of power. In more recent times, the demands of foreign affairs, the dangers of potential adversaries, the sophistication and mystique of new weapons, and especially the development of the means of mass destruction have all given power to our highest military leaders (Reynolds). ......

Ethical Issues Regarding the Use of Performance Enhancing Drugs in Sports

...Ethical issues regarding the use of Performance Enhancing Drugs in Sports In the history of 20th century sports, specifically in the post World War 2 era, there has been an ever increasing use of performance enhancing drugs in all avenues of sport. Sports have become money making machine for both athletes and big business and the “win at all costs” attitude which has permeated itself into all aspects of professional and college level athletics. Winners make money, losers don’t. The temptation of fame, notoriety and million dollar contracts in all venues of sport is a lure for many athletes. Elite professional athletes are worshiped in today’s society. This paper will elaborate on the use of performance enhancing drugs in the sporting world and the associated sports ethical issues. It is a majority belief in all sporting circles that the “true” spirit of sportsmanship does not allow any aspect of performance enhancing drugs. There are several arguments both in favor and against the use of performance enhancing drugs which will be presented and discussed in this paper. While addressing this ethical issue, we need to define the term ethics. Ethics can be defined as the socially accepted norms and values. These norms and values are varied from society to society and are based on culture and tradition. Ethics also could be defined as the unsaid, un-written and understood laws that prevail in a society. Ethics also cover what is right and what is wrong in society and......

One of first publications in the U. S. was on the way spectators viewed competitive bicycling (Brown & Mahoney, 1984). Sports psychology focuses on the knowledge from kinesiology and psychology. Sports psychology involves all of the psychological aspects that are includes in sports. This includes how psychological aspects affect performance, along with how sports can affect the mind and body. Health and sports psychology identify how psychological factors impact health, as well as the aspects of sports. Sports psychologists can employ shaping and chaining, reinforcement schedules, and one-trial learning techniques in teaching new technical skills among athletes. Shaping and Chaining Before identifying how shaping and chaining can be employed to teach new technical skills to athletes, sports psychologists have to understand each process of shaping and chaining. If a behavior does not take place, it is not associated with an individual’s performance or listed in the abilities that he or she is able to perform. Shaping can be used to add behaviors that can help athletes perform, effectively and efficiently. Shaping can identify a behavior that is not present yet and work towards the retrieval of that......

Your wife or husband is in favor of altering your child’s genes so that she or he will be predisposed to be a successful athlete in your favorite sport. Explain in detail (one page) why you would also be in favor of this, or why would you argue against altering the child’s genes in this manner. Being a former student athlete, nothing would make me happier than seeing my son or daughter succeed with athletics. I can only imagine the feeling of seeing your son/daughter hit the game winning shot and watching them excel throughout their lives. With that being said, I would be in favor of adjusting my child’s genetic make up making them a superior athlete. Elite athleticism is what separates you from the average competitor, some people are just born to be a great athlete. While training, diet, and mental fitness are all clearly important contributors to achieving athletic success, the fact that individuals reaching the peak of their chosen sports often suggest a role for genetics. There are many reasons why I would be in favor in changing my son/daughter genetic make up making them the best athlete possible.
