Official title
The Role of Beef in Optimal Protein and Feeding Strategies to Accelerate Muscle Mass and Functional Recovery From Anterior Cruciate Ligament (ACL) Repair
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Musculoskeletal injury, particularly injuries requiring surgical repair, induce significant muscle atrophy, resulting in diminished physical function. The protein turnover-associated (diminished protein synthesis, elevated protein breakdown, negative net muscle protein balance) etiology of injury and surgical-induced atrophy are, in part, similar to those observed with muscle wasting induced by hyper-catabolic and inflammatory conditions and prolonged periods of skeletal muscle disuse (e.g., cachexia and joint immobilization). Combining dietary strategies to optimize the anabolic properties of beef as a high quality protein source that provides essential amino acids prior to surgery and throughout post-surgery rehabilitation may attenuate muscle atrophy and accelerate the restoration of muscle function. This project will examine the efficacy of habitual consumption of a beef-based higher protein meal pattern and post-physical rehabilitation beef protein supplementation throughout post-surgical rehabilitation intervention on skeletal muscle function in response to anterior cruciate ligament (ACL) repair in healthy, physically active adults. Stable isotope methodologies, proteomic analysis of muscle protein synthesis, and molecular assessments of skeletal muscle atrophy and remodeling will be assessed to evaluate the effects of increased protein intake, including consumption of a high quality beef-based protein supplement following patient physical therapy sessions on: 1. Skeletal muscle protein fractional synthetic rates during and in recovery from surgery; 2. Inflammatory, proteolytic, and anabolic intramuscular signaling during surgery and their association with skeletal muscle protein synthesis and muscle function; 3. Muscle size and functional recovery; 4. Duration to return to routine exercise, sport, or physical activity.
