There are many ways that a person must prepare for a marathon. Besides, practicing the ways in which someone runs in order to gain endurance and stamina during the race, the marathon runner must also prepare with the equipment and supplies that they will need during and right after the race.
After running, a person will need several things including water. They must also have ice packs to put on their joints and usually a towel to wipe off the sweat. There are different types of water that the person can drink.
However, the person may want to put back the electrolytes that they lost. Therefore, they will need to pick a certain type of drink to do that. If the person drank distilled water, then they will have decreased plasma osmolarity.
Decreased plasma osmolarity- by sweating and then replacing all volume by drinking h20, the woman has a net loss of nacl without a net loss of h20. therefore, her extracellular and plasma osmolarity will be decreased, and as a result, water will flow from extracellular fluid (ecf) to intracellular fluid (icf). the intracellular osmolarity will also be decreased afterthe shift of water. total body water (tbw) will be unchanged because the woman replaced all volume lost in sweat by drinking water. hematocrit will be increased because of the shift of water from ecf to icf and the shift of water into the red blood cells (rbcs), which causes their volume to increase.
