The Health Fitness Human Performance Essay

People who exercise more will have different diets to those who do not exercise. Carbohydrates are very important for athletes as it provides fuel. Carbohydrate is stored as glycogen in the liver and muscles, and released when needed during exercise. It is easily broken down to provide energy. The other source of energy is fat, but this cannot be converted into energy as quickly as glycogen.

carbohydrates in the form of sugars and starches, it is digested and circulated through the blood stream as a simple sugar. If the glucose is not used immediately for energy, it will go into storage as glycogen in the liver and muscles. When these glycogen stores are filled, the excess glucose is stored as fat. As exercise continues, and more energy is needed, glycogen breaks down to

A lot of people struggle with being self conscious and having no confidence. Working out and eating healthy can help this problem along with many others. There are so many benefits to fitness and a healthy diet. In this essay I will be going over the benefits of working out and eating healthy and how it can boost your self confidence and make everyday better.

It is concluded that most of college going athletes have nutritional knowledge and they consume calcium supplements and weight gain supplements very frequently and lack of time is the most responsible factor for their nutrition intake.

Today’s task is to conduct 4 For the Core, Military Movement Drills 1 & 2, and Hill Repeats. IAW TC 3-22.20.

As the muscles begin to exert force, in order to obtain quick energy, energy must be produced through an anaerobic pathway. The first step of carbohydrate metabolism is glycolysis where a chain of reactions take place to release the energy stored in glucose. Glycolysis is a ten reaction pathway, the first five reaction constituting of the preparatory phase and the final five constituting of the payoff phase. This process all occurs in the cytosol where the glucose molecule is split to form two molecules of pyruvate. The preparatory phase is the production of two molecules of glyceraldehyde-3-phosphate through phosphorylation of a glucose molecule. The consumption of 2 ATP molecule allows this phase to proceed. Reaction 1 is catalysed by hexokinase and is the phosphorylation of glucose to form glucose-6-phosphate. The phosphate group from ATP is transferred to glucose forming glucose-6-phosphate. This reaction is an exergonic reaction with a ΔG˚’=-16.7KJ/mol and the energy released by hydrolysis of ATP drives the reaction forward. Reaction 2 involves the isomerization of glucose-6-phosphate to fructose-6-phosphate. This reaction is catalyzed by phosphohexose isomerase and is an endergonic reaction with ΔG˚’=+1.7KJ/mol. In reaction 3, fructose-1-phosphate is further phosphorylated to produce fructose-1,6-bisphosphate. Second ATP is consumed in this endergonic reaction with ΔG˚’=

Nutrition and fatigue are two major areas of exercise and sport. Sport and nutrition together can be a major factor in preventing fatigue, and maintaining a good diet can help keep the athlete consistent with training and performance without the training load being too detrimental and leaving the athlete with excessive fatigue, illness or recurring injuries. Training and eating becomes a cycle of preparation and recovery, with meals and snacks consumed after one session becoming the pre-event meal for a subsequent workout. The ingestion of carbohydrates, fats and proteins all aid in the promotion of optimal training and performance. As well as food fuels, recovery is a significantly important factor in regards to having an adequate training session or

Carbohydrates are made up of 3 things carbon, hydrogen and oxygen. Which are broken down into glucose that will circulate the body via the bloodstream then will be turned into glycogen when stored in the liver and muscle cells for later use as it provides fast-release energy. This is the easiest form of food transformation into energy.

How ever there was a huge change in food intake after participants engaged in High Intensity Exercise. There was a difference shown with a significance of (P<.05). This helped the researchers come to the conclusion that High Intensity workouts are beneficial for the 24 hour energy balance. However it found that these effects usually don’t carry over into the next day. It also showed that while the consumption levels fell the types of food which they consumed did not change

Overall, all the participants did not meet recommendations for CHO, Vitamin A, D, C, B1, and B6 during training and, in addition, women did not consume the recommendations for PRO, calcium, iron, and zinc.5 Furthermore, during the race 75% of the runners doing the 60- km race fell short on getting the recommend CHO. For the 120-km runners, 3 of the 4 men took in greater than 500 ml/h of fluid, which met recommendations, but only 1 runner took in greater than the recommended CHO during the race (108 g/hr). One major limitation of this study is that the four runners PRO, sodium, and fat intakes weren’t recorded during the 120-km

Carbohydrates are one of the main fuel sources of energy. Carbohydrates are made of carbon, hydrogen and oxygen molecules. Monosaccharides (glucose and fructose), disaccharides (sucrose) are referred as sugar molecules. Aerobic and anaerobic metabolism work together to provide ATP and energy for exercise (Baker et al, 2010). Skeletal muscles use fat and carbohydrate for energy. Therefore, at high exercise intensities, fat does not synthesis ATP, so fat utilisation has a higher amount of ATP. Therefore, glucose utilisation is necessary for ATP synthesis (Milian, 2013).

The body derives it 's energy from four key fuels 1) glucose 2)proteins 3) free fatty acids 4) ketones. The primary determinant of the fuel utilized is the availability of carbohydrate. The body has three storage units that can be utilized during times of calorie deprivation: 1) carbohydrate, which is sotred in liver and the muscles 2) protein, which can be converted to glucose in the liver 3) fat, which is stored primarily in adipose tissue. Under specific conditions a fourth fuel comes into play -ketones which are derived from the incomplete breakdown of free fatty acids. Under normal dietary conditions ketones play a minimal role in energy prodcition. During times of Low carb dieting or starvation diets ketones impact energy production significantly.

Physical Activity is undeniably good for everyone, not only does it keep you fit and healthy but when started at a young age, it can set up good habits for life. Sometimes however, people do not take care of their physical wellbeing, resulting in obesity and other eating disorders which can be detrimental to their health.

Footballers nutritional needs play an important role in becoming an elite player, in fact the importance is so highly important that every elite level player knows it’s importance and follows a specific diet in their respective clubs and their personal lives. One of the greatest managers to ever grace the game Arsene Wenger has also mentioned “food is like kerosene. If you put the wrong one in your car, it’s not as quick as it should be” (Wegner, 2003). To create a perfect diet different factors should also be considered such as timing of every meal, the amount of calories and carbs needed, hydration, micro nutrients, vitamins, fats and protein. All these

The articles by Erikson et al., Gatz, Korol et al., and Draganski et al. explore the concept of increased physical activity and/or mental activity having effects on the cognitive function and development or deterioration of the brain as we age. Although I agree that physical exercise is critical in increasing cognitive function because of the health benefits it provides, as well as the increased blood flow and circulation throughout the body, I ultimately believe that a healthy brain is not achieved solely by physical exercise or mental exercise, but both. I think there is a link between physical and mental exercise, and that the combination of these two activities creates higher cognitive functioning of the mind as well as the body. The mind and body come together and meet to make an overall healthy individual.
