Help Close previous l 12 of 13 l nextExplanation / Answer
1. Glucose is the major source of carbohydrates which is broken down for energy during glycolysis. Glucose is a simple sugar that is used by the body as fuel. It is the only energy source that can be utilised by the brain.
2. Glucose is stored in the muscle and liver as glycogen.
Glycogen is a polymer of glucose produced by the breakdown of glucose by insulin activity. It is stored in the muscles and liver and acts as a readily available source of energy whenever the blood glucose level is low.
3. In order to maximise the glycogen availability, many athletes follow a carbohydrate loading schedule before a big event.
Carbohydrate taken prior to exercise or a sport event in the form of sport drink, bars etc., help maintain blood glucose level and prevents premature fatigue and decreased preformance. Thus food rich in carbohydrates help in improving glycogen replacement and are helpful during times of intense training and competition.
4. It is not recommended that athletes reduce carbohydrate consumption in order to lose weight because carbohydrates are necessary for energy production.
5. Choosing high glycemic foods is beneficial during post recovery period to maximise glycogen production.
High glycemic foods is necessary to replace stored muscle glycogen and initiate muscle glycogen synthesis.
6. Atheles should consume foods that contain sufficient B Vitamins because they are necessary for energy metabolism.
B vitamins such as thiamine, riboflavin, Vit B6 and VitB12 and folate are necessary during body's process for converting proteins and sugars into energy.The stress on the body's energy production , changes in the body's tissue resulting from competition or exercise , loss of nutrient requires VitB for recovering.
7. Improper nutrition can result in dehydration, physical injuries and eating disorders.
Poor nutrition increases the risk of injury.The body must be provided with sufficient daily energy needs that does not limit the storage of carbohydrates in muscle and liver.
8. A poor diet can result in osteoporosis which will further impact athlete performance due to increased risk for fractures.
Osteoporosis in athletes is due to tloss of trabecular bone found on the vertebrae and neck of the femur. Decreased calorie intake with high fibre diet reduce calcium absorption. This may lead to decreased bone density and are finally ended with fractures.
