Rat Supraspinatus Tendon Responds Acutely and Chronically to Exercise

The objective of this study was to identify acute responses and chronic adaptations of supraspinatus tendon to non-injurious exercise. We hypothesized that chronic exercise increases tendon mechanical properties, and a single exercise bout increases MMP activity acutely. Rats were divided into acute or chronic exercise (EX) or cage activity (CA) groups.
