Explain the relationship between diet and exercise

Introduction

Explain the relationship between diet and exercise Nutrients are chemicals that fulfil specific functions in the body. They provide energy, help construct body tissue and supply body regulators to control metabolic functions. " Your local grocery shop is the best source for the 37 (three macronutrients, 13 vitamins, and 21 minerals) essential nutrients needed by the body on a regular basis" (Forsythe, 1990, www.calstatela.edu) Williams (1988) has identified what he labelled as the ten key nutrients that are central to human nutrition (see appendix 1). To ensure that the recommended daily allowance of macro- and micronutrients is consumed then you must choose to eat foods that have a high nutrient density or foods that are high in vitamins, minerals and fibre but are low in calories. Although the primary source of energy during exercise is derived from free fatty acids, carbohydrates (in the form of glycogen) is also needed. "Several studies, that compared high fat or low carbohydrate diets to mixed or high carbohydrate diets, demonstrated a significant performance advantage to the high carbohydrate groups" (Keith, 1989, www.calstatela.edu). ...read more.

Protein foods are used by the body after 45 minutes of exercise which again is ideal for football. Research shows professional outfield players run about 5-8 miles in a game and are in personal possession of the ball for a total of 3 minutes. As a result they use up huge amounts of carbohydrate energy. These carbohydrates must be replaced after the match. However two days prior to the match professional footballers increase the amount of carbohydrates they eat. In this way their muscles are fully prepared for the exercise within the match. Outline the role of macro and micronutrients, vitamins, minerals, dietry fibre and water in an athletes diet It is also very easy to dehydrate during exercise especially during summer months. Drinks which are very fizzy or very cold should not be drunk during periods of exercise as they often lead to stomach pains. Also drinking great quantities should be avoided for the same reasons, the rule 'little and often' should be followed. ...read more.

Conclusion

Observational studies measure dietary intake and fitness in groups (e.g., ecologic studies) or individuals (e.g., cross-sectional, case-control, and cohort studies). Among observational studies, cohort studies provide the strongest evidence of a link between diet and fitness. In this type of study, dietary information is obtained from individuals in a large population which is followed over time to observe the development of there fitness. Cohort studies indicate whether individuals with differing dietary intakes vary in their levels of fitness. Experimental studies include randomised controlled trials (RCTs) and basic research experiments (e.g., laboratory animal studies). Basic research experiments can help to identify diet-fitness relationships. However experimental animal findings cannot be readily compared to humans. A relationship between diet and fitness becomes more clear when relevant data from several different types of studies are consistent. Different diets have different effects on your performance, each sport is also different and requires different kinds of diets to enable them to reach there optimum performance. As I stated earlier your diet can often distinguish between winning and loosing at the top level, that's how important your body's physical shape is to your performance. ?? ?? ?? ?? ...read more.
