Sports Injuries and First Aid: Why Ice May Not Speed Healing
How sports injuries happen, how to prevent them, and what to do in the first minutes when something goes wrong.
Try 3 questions
1. In injury biomechanics, when does a tissue injury occur?
- When load exceeds the tissue's capacity
- Whenever a muscle is used intensely
- Only when a bone is struck directly
Show the answer
Answer: When load exceeds the tissue's capacity
Tissues tolerate loads up to a limit; injury results when a single load or the accumulation of loads exceeds what the tissue can withstand.
2. How do most anterior cruciate ligament (ACL) tears in sports like football happen?
- Without contact, landing or cutting
- During slow, steady jogging on grass
- From a direct blow by an opponent
Show the answer
Answer: Without contact, landing or cutting
Around 70% of ACL tears are non-contact, typically when the knee collapses inward during a landing, sudden stop or change of direction.
3. Compared with male athletes in the same sports, the ACL injury rate in female athletes is roughly what?
- Two to three times higher
- Essentially the same rate
- About half as high as men's
Show the answer
Answer: Two to three times higher
Differences in landing mechanics, neuromuscular control, anatomy and hormones likely contribute; targeted training reduces the gap.
