Question

which of the following is a benefit of a proper warm - up before exercise?
a. increased risk of injury
b. improved blood flow to muscles
c. slower reaction time
d. decreased muscle flexibility

what role does proper technique play in injury prevention?
a. reduces the risk of injury by ensuring biomechanically correct movements
b. improves cardiovascular endurance
c. increases muscle strength
d. enhances mental focus

Explanation:

• For the first question: A proper warm - up increases blood flow to muscles (not a, c, or d which are negative or incorrect effects).
• For the second question: Proper technique reduces injury risk via biomechanically correct movements (b is about cardiovascular, c about strength, d about mental focus - not related to injury prevention via technique).

Answer:

1. B. Improved blood flow to muscles
2. A. Reduces the risk of injury by ensuring biomechanically correct movements
