warm - up routines increase body temperature. what other effect do they have on the body?
○ a. they increase blood flow.
○ b. they decrease blood flow.
○ c. they increase hydration levels.
○ d. they decrease hydration levels.

Explanation:

Warm - up routines prepare the body for physical activity. When the body is warmed up, the blood vessels dilate. This dilation leads to an increase in blood flow. Hydration levels are mainly affected by fluid intake and loss (such as through sweating during exercise, but not directly by the warm - up routine itself).

Answer:

A. They increase blood flow.
