Question

why is building up to full uniform/padding a good idea in preventing heat illness during practices?
students can run faster when not weighed down by gear.
students need to get acclimatized to heat and exercise intensity before wearing heavy gear
students need to build up their muscles before wearing full gear.
removing gear makes it harder to cool a student down when overheated.

Explanation:

When it comes to preventing heat illness, getting acclimatized to heat and exercise intensity is crucial. Wearing full - uniform/padding right away can lead to overheating. Gradually building up (by first getting used to the heat and exercise without full gear) allows the body to adjust. Running faster (first option) is not related to heat illness prevention. Building muscles (third option) is about strength, not heat - related. Removing gear (fourth option) is the opposite of what the question is about (building up to full gear).

Answer:

Students need to get acclimatized to heat and exercise intensity before wearing heavy gear.
