James is a 14 year old boy who is very athletic and eats lots of food. Not everything is as nutritional as it should be and the following will share the positive benefits of making good food choices, including some recommendations.
Young people are in the ‘ready,go’ mode when it comes to participating in an athletic event. Most of these young people, as our case participant, James, thinks eating anything will give them what them to achieve their goal. Downing a doughnut and drinking a bottle of Gatorade will not do the trick, nor will it provide nutrition to enable them to be a good athlete. Many young athletes don’t figure into the equation that good nutrition is a vital part of their performance and how important it is to learn this.

Both are necessary and effect their growth and development as many young athletes have very low intake of the right carbohydrates and micronutrients, running on low energy, essentially causing hurt to their …show more content…
When a person does not have the proper balance of carbohydrates, it causes the body to work harder than it should and ushering in fatigue, faster. Glucose is a sugar in the body that is designed to kick in during any type of physical activity; it is the fuel your body needs to workout. Carbohydrates provide that glucose. If the body does not have enough glucose it will use the energy from muscles which is protein. When there is a deficiency in calcium that causes weak bones and does not allow the nerves impulses or muscle contraction to respond properly (Thomas and Manore 2006). Not having enough calcium puts the young athlete at risk for fractures and other injuries. Vitamin B deficiencies along with folate are very important to metabolism and the health of blood. A lack of these nutrients, including iron, especially for the female athletes can also lead to fatigue, muscle soreness and the ability to concentrate, which is necessary for those who are in athletic competitions.
Recommendations:
Stay hydrated. All athletes must replenish the fluids lost when exercising. It is a good rule of thumb to weigh before and after to see how much you have lost. This loss of weight will more than likely be fluid. The general rule of thumb is drinking 16–24 ounces of

The physical demands of tournament tennis players can be and usually are very grueling. The body is using both anaerobic and aerobic metabolism along with anaerobic and aerobic muscle fiber types. Tennis is a high intensity sport requiring hundreds of short bursts of activity. Most points only last around 10 seconds(anaerobic) but there is only 25 seconds of rest in between points and 90 seconds of rest in between games which requires the player to have endurance(aerobic). Tennis matches can be long and drawn out, lasting hours or they can be fast, intense and only last an hour. This means having adequate nutrition along with an efficient metabolism is key to being able to compete at the highest level.
Early summer, about forty-eight years ago in 1965, University of Florida assistant football coach, Dwayne Douglas, sat down and wondered why so many of his players were suffering from heat strokes and heat related illnesses during games or practice. So, he went to the university physicians and asked them to determine why this was happening. Not long after it was discovered that two key factors were causing the Florida Gator players to suffer from these conditions: the fluids and electrolytes the players were losing during the events were not being put back into the body, and the massive amounts of carbohydrates the players' bodies used for energy were not being replenished. So, he decided to create Gatorade. There are plenty of Gurus out there who will sit and tell you that water is natural and it’s the best thing you could ever put into your body, but let’s get real I’ll take scientifically proven research over someone’s “word” any day.

A NASCAR drivers’ training regimen throughout the season and during the off-season shows strong evidence that they are athletes. Nutrition is a key ingredient in the success of athletes in other sports, so NASCAR drivers and their crews practice healthy eating choices. On race day, nutrition is especially important for the crews. They eat no greasy foods for breakfast and load up on carbs for lunch so they can last the entire day at the track (Herlocker). Their diet proves that nutrition is key for the success of not only the drivers but for their crews as well.
To find the answer we performed an experiment. We decided to put the drinks to the test by exercising, and then seeing how well we shoot 10 free throws. But after we exercised we drank either Powerade or Gatorade. We would then collect data, analyze it, and ultimately find out which drink is more effective. When I finished working out on Day 1, I drank Gatorade. I made 8/10. On Day 2, I drank Powerade after exercising and shot 7/10. And since the results were very similar I decided I would exercise and shoot 10 more on Day 3. But instead of drinking a sports drink I just drank water. I made 7/10. This data was very interesting. It shows Gatorade improved performance more, but nothing really stood out. So unless you plan on running a marathon or other strenuous athletic tasks, it will not really matter if you drink Powerade or Gatorade. Our experiment even showed, no matter how many fancy sports drinks come out, water is always a very reliable option when it comes to regaining lost

For purpose of emphasis and understanding, some background information is needed to fully understand exactly what blood doping can do for an individual. In order for muscles to perform, they need a ready supply of oxygen. During high intensity exercise, oxygen is depleted and the body can not get enough oxygen to the muscle in order for them to perform their optimal potential. This lack of ability to get oxygen to the muscle is called oxygen debt and results in lactic acid being formed. Lactic acid is a waste product of anaerobic cellular respiration within the muscle tissue, which can cause muscle sourness that, usually, is felt after a hard or long workout. Fatigue usually sets in with the onset of lactic acid production. Oxygen is carried to the muscle by two delivery systems. Three percent of oxygen is carried in plasma and ninety-seven percent is in hemoglobin, the principal protein in erythrocytes (red blood cells). If hemoglobin amounts are increased, this will lead to increased oxygen levels that can be transported to the muscles. Allowing the muscles to become more fatigue resistant.

Today, our world is filled with food. While some are healthy, it seems like teenagers are more focused on the unhealthy foods. Yes, there are athletic programs; teens are still not eating the right foods they should be. They get the simple, easy to depend on, low cost foods which most likely are from fast food restaurants. Teenagers often pick the easy choice, which is why the obesity rate is rising in our state, including heart attacks and diabetes. Even though it seems like the unhealthy choices are more dependent when you’re in a rush and need a quick bite to eat, not caring about the nutrition, teenagers don’t realize that it will affect them in the long run, literally.
Unfortunately, in today’s society, school administrators focus heavily on standardized test scores and school rankings thus adding more pressure on students and teachers. This being said, schools have begun to focus on providing healthy foods because they help increase a person’s cognitive and critical thinking ability. It is seen that nutrition plays a great role in students’ performance on exams and physical activity due to the correlation between school provided meals and low student
Whether it is on a track, a pitch, court or rink, nutrition is of vital importance in the development of a healthy, competitive athlete. Athletes must depend on highly nutritious and vitamin rich to keep their body at their healthiest, their mind focused to maximize their performance.
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.
There is a relationship between food and exercise and people do not understand that. Everyone needs food in order for their body to work properly and do their daily activities, especially exercising. Without good nutrition, one will not be able to exercise effectively. To exercise effectively, one need the right caloric intake, energy, and nutrients in one’s body. The human body needs have carbohydrates, protein, fats, vitamins, minerals, and water to fuel it up, just like the car needs gas to run. Everyone should fuel their body with right foods so that they can maintain their energy levels. Bananas and lean white meats are examples of excellent sources of natural energy that can help the function properly and achieve fitness goals. Bananas are an excellent food to eat because they contain high potassium, makes the mind alert making the brain smarter, builds strong bones, and keeps the digestive system regulated. Lean white meat such as chicken and fish are good to eat because they make the tissues in the body healthy. Good nutrition is more important because if the body absorbs the nutrients it needs, one will be able to exercise very
