Dietary Needs Comparison
November 12, 2015
Are you an athlete? Hydrated? Hungry? Healthy? Dieting and exercise are only two components of safe practices in athletics. This writing is a comparison of the position statements/stands of the nutritional needs for different types of athletes based on the recommendations of the National Athletic Trainers’ Association (NATA), the International Society of Sports Nutrition (ISSN), and the American College of Sports Medicine (ACSM). Following the comparison, a detailed overview of the nutritional needs of athletes within each of the following categories will be described: ultra-endurance/endurance, strength/power, and intermittent activities. In doing so, the types of

In order to accomplish this bout involves the increasing of anaerobic capacities. ATP-PC system and glycolysis are the energy systems used when these athletes perform. This athlete needs more protein in their diet than other athletes. These athletes must pay attention to protein intake because too much protein causes dehydration, overburdens the liver and kidneys, and interferes with calcium absorption. Fat intake is also higher than regular healthy individuals. 24-40% of glycogen stores are depleted after a training or performance bout. Carbohydrates are essential in their diet too. An experiment concluded that immediately before and after a training or performance bout, a supplement of protein, creatine, and carbohydrate was consumed, and it caused a great increase in strength and muscle protein synthesis. Nutrition during the activity is obsolete because the activity is such short-lived. The athletes are encouraged to always begin training only if properly hydrated and to replenish their fluids according to how much water weight was lost during the …show more content…
Loren Cordain created the Paleo Diet to mimic caveman and stone-aged eating. The theory states that if the caveman didn’t eat it, neither should we. In return, we shall live a healthier, fitter, and disease-free life. The main foods consumed are animal protein and plants. The restrictions include only 23 percent daily value of carbohydrates, and the diet is costly. The advantages for athletes, especially weight-controlled sports, the athlete will stay lean, strong, and energetic. The disadvantage for all athletes would be the lack of carbohydrates in the diet. Foods other than bread, pastas, and rice include carbohydrates, but the athlete should still be aware that there could be a lack of a major macronutrient in their diet. A new program for athletes was implemented because of the lack of carbohydrates. This implementation to the Paleo Diet allowed for the intake of different foods in order to make up for the

Ultimately, sports nutrition can be very interesting and should be taught to all. There are 7 types of nutrients the should ideally be consumed in our everyday meals. This will help with physical and mental health.

Of the 258,000 athletes that wrestle in high school, only 7,408 are able to continue their career as a wrestler in college (NCAA 1). These 2.7% of wrestlers are faced with multiple adversities from making weight, to the long seven minutes of nonstop action on the mat. Although the seven minutes go buy quick when spectating, when you 're on the mat it seems never ending. A lot of work goes behind ones success on the mat. To be successful in college wrestling on must cut weight efficiently, lift weights, and warm up effectively before every match.Among college wrestlers, cutting weight is a big part of their lives. College wrestlers often believe that cutting weight will improve their chances of winning. They do this be dehydrating themselves before weigh ins, then shortly after weigh ins replenishing their fluids as fast as possible. For this technique to be effective the athletes must do it right. If not done right, the wrestler will only weaken or fatigue themselves before the competition. As the college wrestler rushes to replenish his water, electrolytes, and glycogen after weigh ins, they think by competition they will be hydrated and that their muscles will be fueled again, but it does not work that way. Replenishing body fluids takes 24-48 hours, and muscle glycogen replenishment can can up to 72 hours. Not only does cutting weight have short term effects, but has long term effects as well. This includes organ damage, eating disorders, and unhealthy eating habits.
Good nutrition and its role in positively affecting athletic performance has become more and more evident almost daily. Specific macro and micronutrients are better understood as to their specific functions within the body and from that how they can influence the body’s ability to perform while under duress. An example of such would be the stress of athletic performance. Vitamin D, which is also referred to as cholecalciferol, is one of the fat soluble vitamins that have been attributed to influencing athletic performance. However, vitamin D is not as much a “performance enhancing” nutrient in the sense that when taken in higher amounts it will aid athletic performance, but rather when in deficient amounts it can hinder athletic performance.
Education plays a dominant role in the lives of students all over the United States. Since most students spend roughly eight to twelve hours in school, it is important to make sure that they are provided with a healthy and nutritious breakfast, lunch and snack.

Proteins are extremely important in the growth of muscles, combined with weight training; protein can enhance muscle mass gain. Dependent on the athlete, the balance between weight lifting and protein intake will vary; a professional or trainer will measure the needed amount. Thought, all athletes will need a high protein diet, short track sprinters will not intake as much as much as a football player, for the sprinter would have a high carbohydrate diet. Resulting in instant energy opposed to the football players need for muscle mass and stored energy for long exercise periods.
Since we have been learning about nutrition in class, our task was to record a food log. Nutrition requires a well-balanced diet containing nutrient and vitamins like amino acids and fatty acids. Over the past seven days I have been recording and have been looking very carefully at my intake of nutrients, minerals, vitamins, and fats. In our task, the objective was to record the basic foods we ate during the period of seven, but it did not require recording every single detail or our intake of food. Doing this food log was a pain and it was disturbing because I never wrote about what I ate like breakfast, lunch, dinner, or additional meals. I found this food log useful because it helped me learn what I can change in my intake of foods to make my diet healthy and to see what about my diet is affecting me from being healthy because I could affect me in the future.
Nutrition and fitness play two of the most important roles in human health, and it is not difficult to understand some of the consequences for ignoring their significance. Ignoring proper nutritional and fitness habits can lead to extreme health risks such as obesity; most of which will eventually cause serious health issues up to and including death. To decrease these serious health risks and promote favorable personal health, one should incorporate positive nutritional and fitness habits.
Certain foods can make a difference in sports competition. Conditioning, strength, and speed have been the focal points of athletic training for years; however, the research on nutritional elements indicates their importance to an athlete's optimal performance. Knowing the proper food to eat before, during, and after a physical activity can help an athlete in achieving their desired performance.
Innumerous scientists confirm that nutrition and dietary supplementation can deeply affect molecular and cellular processes that occur in the body during the exercise and the recovery process. This brief review analyzes the potential for performance enhancement through protein supplementation ingestion, and the importance of nutrition education for sports supplement users.
This diet consists of: seafood, meats, fruits, vegetables and nuts. According to Loren Cordain, the author of The Paleo Diet, “The diet decreases the body’s glycemic load, expands the vitamin and nutrient consumption, has a healthy ratio of saturated and unsaturated fats, and consists of a good balance of fat, protein and carbohydrates.” (2). This diet is all about eating fresh foods and foods directly from nature. There are many things you cannot eat when you are on this diet. Some examples are: grains, dairy and processed food. Processed food is anything that comes in a jar, box or bag. I feel as if this diet is hard to stick to nowadays because most people find it convenient to just heat something up or grab a snack and go. There are many advantages as well as disadvantages to the paleo diet. Some advantages include: losing weight, no chemicals or additives, and a larger intake of iron and protein.” (Bonci 1). This diet will definitely make you feel better about yourself as a result of weight loss and consuming healthy food. Along with these advantages there are just as many disadvantages. Some of these disadvantages include: no grains or dairy which are essential for energy, strong bones and health, you can potentially have a nutrient imbalance, it is a hard diet for athletes, picky eaters and vegetarians and these foods tend to be more pricey (Bonci 1).
