What do sports injuries of the hip and asthma have in common?
There are two reasons why repetitive, overuse injuries occur: the exercise demands on the body exceed the body's endurance capacity or the exercise demands on the body exceed the body's core strength.
With exercise induced asthma, the endurance capacity is limited and fatigue results in the smaller hip muscles being overpowered by the much stronger quadriceps.
Once the core muscles fatigue, there is a bio-mechanical breakdown that affects the whole leg, whether running cycling or doing any other activity.
The result? Overuse injuries.
Since we started performing exercise testing on endurance athletes with overuse injuries, they have controlled their underlying medical problems, improved their overuse injuries and they are faster as well.
