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.

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

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
