Question

multiple choice question
swelling techniques such as sponging the head and face with cold water or using a water spray have been shown

improve cardiovascular responses to exercise
decrease core temperature
to decrease sweat loss

Explanation:

Cold - water sponging on the head and face or using a water spray cools the body. This helps in reducing the core body temperature during activities. It doesn't directly improve cardiovascular responses to exercise. Also, sweating is a cooling mechanism, and these techniques don't reduce sweat loss but rather help manage heat by cooling the surface, which in turn can influence core temperature.

Answer:

decrease core temperature
