Question

Maria is a 121-lb endurance athlete who is planning to employ carbohydrate loading before her next race. Which strategy correctly follows the guidelines for carbohydrate loading?
Choose the statement below that correctly describes a good carbohydrate loading strategy for Maria:
O Four to six days prior to the event, Maria should consume 550 g of carbohydrate daily and decrease to 220 to 275 g of carbohydrate daily 1 to 3 days prior to the event.O One to three days before the event, 550 g of carbohydrate daily is recommended.O One to three days before the event, 1210 g of carbohydrate daily is recommended.O Six days before the event, her carbohydrate intake should be 550 g per day.O Two days before the event, an intake of 33 g of protein daily is adequate.

Answer 1

Answer:

Four to six days prior to the event, Maria should consume 550 g of carbohydrate daily and decrease to 220 to 275 g of carbohydrate daily 1 to 3 days prior to the event.

Explanation:

Carbohydrate loading is for constant  supply of  constant energy as ATPs for the skeletal muscles cells during high intense activity, to reduce fatigue, and increase performance for upmost performance.

The   main objective  is to  sustaining muscle  contraction during intense  exercise  

The practice   involved increase in   intake of high carbohydrate meals  a   few weeks before the commencement of the sporting activities. This is stored  as  muscle glycogen, as well as in the  liver glycogen and brain.  

The physiology involved  the conversion of  muscle glycogen  to glucose -6-phopahate in the liver, and its entry  into Glycolysis, and Krebs’s cycle to generate ATPs.

The use of muscle glycogen during strenuous exercise reduces   blood glucose uptake, and ensured that its level is at a relatively constant value for the body homeostatic conditions, without exogenous carbohydrate intake
