Answer:
Step-by-step explanation:
During long training sessions in high temperatures, the body tends to lose both water and electrolytes through sweat. Electrolytes are minerals that play a crucial role in maintaining fluid balance and muscle function. Therefore, the army member's choice of purified water with electrolytes is a good one. By choosing water with electrolytes, the army member is replenishing not only the lost fluids but also the important minerals needed for proper hydration. Electrolytes, such as sodium, potassium, and magnesium, help regulate muscle contractions and prevent muscle cramps. They also aid in maintaining proper nerve function and hydration levels. Drinking purified water with electrolytes helps to prevent dehydration and maintain optimal performance during training sessions in high temperatures. It ensures that the body is replenishing both fluids and essential minerals, which are necessary for muscle function and overall well-being. In summary, during long training sessions in high temperatures, the army member's body likely needs purified water with electrolytes to replenish lost fluids and maintain the proper balance of essential minerals for hydration and muscle function.
