What to know
Although a weekend athlete can experience overuse injuries, they are far more common among people who do the same exercise repeatedly or often. And it's happening more often to aging baby boomers. Also known as chronic or stress injuries, overuse injuries are brought on gradually by wear and tear from a repetitive activity such as cycling, running, or hitting a tennis ball. The result: microscopic trauma to muscle, bone, tendon, or ligament, which in turn leads to inflammation or tissue damage.
