Answer:
Skipping a cool-down can cause them.
They take rest to heal.
A broken bone is one type.
Tendonitis is one type.
Step-by-step explanation:
Overuse injuries represent any type of muscle or bone injury caused by repetitive trauma as tendinitis or stress fractures. The most common overuse injuries are from muscle and bone overuse, when the athlete don't rest properly, the excess of activity push muscles and bones out of the limit. Also, training errors conduct to these injuries.
Overuse injuries can be caused by skipping cool-down periods, or rest periods, that's what get the athlete in a overuse state. After these injuries occur, to rest is mandatory, it's the only way to heal, because muscles and bone need to stop to recover from the wide time use.
In addition, as we said before, tendinitis and stress fractures are the most common overuse injuries, due to the overuse of tendons and bones, at that point, they stress and become vulnerable.
