Final answer:
Safety equipment such as wrist, elbow, and shoulder guards are necessary in sports to prevent injuries.
Step-by-step explanation:
Wearing safety equipment such as wrist, elbow, and shoulder guards is necessary in sports to prevent injuries. These guards provide protection to the vulnerable areas of the body and absorb impact during physical activities. For example, wrist guards can prevent wrist sprains or fractures when landing after a fall in skateboarding. Elbow guards can help cushion the impact during a fall in rollerblading. Shoulder guards can protect the shoulder joint from dislocations during contact sports like football.
