Which of the following is a component that raises heart rate during a warm-up?

• A. Pulse raiser
• B. Rest
• C. Cool-down
• D. Maximum effort sprint

Answer: (A)

Raising heart rate during a warm-up is about preparing the body by increasing circulation and core temperature so the muscles are ready to work. The pulse raiser does this with light activity such as jogging or skipping, gradually getting the heart beating faster to a safe, effective level. Rest wouldn’t raise the heart rate; it keeps it low. A cool-down is used after activity to bring heart rate down, not to raise it. A maximum effort sprint would spike heart rate quickly but is too intense to start with and isn’t used as the main warm-up. So the pulse raiser is the part that best achieves the goal of elevating heart rate during a warm-up.
