This trial will investigate the effects of an exercise intervention on retired American professional football (APF) players. A total of 20 retired APF players (≥ 18 years of age), who suffer from chronic pain, will be enrolled and perform a 18-month exercise intervention which involves 90 exercise rehabilitation training visits. They will also be tested on various measures of health and function at baseline, 6 months, 12 months, and 18 months.
The purpose of the study is to investigate the effects of an exercise intervention on retired APF players. This study has previously been approved by the FDA for a different condition.
