Caloric and Energy Requirements
Acceptable Macronutrient Distribution Rangers or AMDRs were established from evidence levels of consumption, which either increase or decrease the risk of developing disease conditions (Otten et al., n.d.; USDA, n.d.). These disease conditions include coronary heart disease, obesity, diabetes and cancer. An AMDR refers to a range of food intakes aimed at reducing the risk of these disease conditions. At the same time, AMDR provides sufficient intakes of essential nutrients, which meet the body's daily nutritional requirements for health and energy. In order to accomplish these goals, an average adult should obtain 45-65% carbohydrates, 20-35% from fat, and 10-35% from protein sources (Otten et al., USDA).
Greg, who is a 19-year-old basketball player, weighs 84.82 kilograms. He stands .96520 meters and has a body mass index or BMI of 22.5. Energy balance depends on intake from energy derived from food and drinks and the amount of energy used (Otten et al., n.d.; USDA, n.d.). Factors, like age, body composition, sex, and level of physical activity determine energy use and requirements. An excess or lack results in weight loss or gain. Estimated Energy Requirement or EER is the average dietary intake of energy, scientifically...
The total is 628,350.42. His BMI of 22.5 is within the normal range. The USDA does not set a recommended level for energy, as energy intakes above EER are likely to increase weight. But when energy intake is lower than energy needs, the body uses energy reserves to function, primarily from adipose tissues. An abnormally low BMI tends to decrease the capacity for work and voluntary physical activity as a whole. This is not the case with Greg.
These data are consistent with the requirements and recommendations of the United States Department of Agriculture.
Other Suggestions
An adult like Greg should devote an average of 60 minutes a day to moderately intense physical activity, such as walking or jogging and at an average distance of 3-4 miles per hour (Otten et al., n.d.; USDA, n.d.). Otherwise, he should spend shorter period of more vigorous activities, like basketball, which he…

Sports Science and Sports Medicine- An Overview This is a paper about "Sports Science and Sports Medicine." 6 sources are given. (Harvard style) Sports/exercise science and medicine are fields that have only recently begun consolidating into distinct professions. They are both interrelated, the former being more of an investigative and experimental area while the latter deals with the implementation of the knowledge and techniques developed by sports science. They are still in the
Conclusion Originally, the main objective of sports medicine was the welfare of competitive professional athletes, but it now encompasses treatment of anyone engaged in sport and exercise. It is becoming an increasingly important branch of the overall medicine field. More general practitioners are being trained in sports medicine than ever before. The training gives them a better understanding of the physical, physiological, and psychological demands of exercise. This helps them to diagnose
In conclusion, it is a commonly established fact that horses used in sports, and particularly in polo, require a level of special care in order to ensure their longevity and well-being. The current paradigms regarding animal care mandates that no animal should suffer cruelty at human hands. This also extends to the treatment and care of polo ponies. Owners are to do all in their power to prevent injury or
Assessment is best performed during the "preswelling period on the sidelines" according to Trojan and McKeag (1998) The avoidance of "chronic ankle pain, laxity, or arthritis can be accomplished through "appropriate treatment." The following table illustrates the differentiation in ankle injuries that exists: Table 1.

Sport Drink Facts and Fictions Sports Drinks Commercial sports drinks make many claims, such as giving athletes 'wings' (Red Bull GmbH, n.d.), "Seizing Every Advantage" (PepsiCo, 2013), or "Go Stronger for Longer" (Coca Cola Co., 2013). Red Bull's Energy Drink contains 320 mg of caffeine and 110g (11%) of sucrose and glucose per liter (Red Bull GmbH, n.d.). Gatorade Thirst Quencher contains 58.3 g (5.8%) of sucrose and dextrose per liter of
Athletic Training Whether to win marathons or to make it to the state football championships, all athletes need some form of training. Lately, increased focus has been placed on the specific importance of weight, or strength, training for the overall conditioning of a casual or professional athlete. The terms "weight training" and "strength training" are technically different, but often the two terms are often used interchangeably. Typically, weight training implies the
