Warfighters sustain musculoskeletal injuries (MSKI) because of the significant occupational demands of physical training and combat operations. Injury-related impairments in physical performance limit the ability to train, compromise Warfighter readiness, and make Warfighters non-deployable. MSKI requiring surgery and/or limb immobilization (e.g., anterior cruciate ligament reconstruction, bone fractures, joint dislocation, stress fracture) are especially detrimental given the rapid loss of muscle mass and function that results from decreased muscle loading and activation post-injury. Recovery from these MSKI often requires extensive rehabilitation to restore muscle mass and physical performance to levels required of full duty status, with many Warfighters experiencing post-injury restrictions even after extensive rehabilitation. Developing targeted recovery solutions that support return-to-duty is therefore essential for Warfighters that do sustain injuries.
Disuse-induced losses of muscle mass after MSKI are driven by alterations in muscle protein turnover (i.e., muscle protein synthesis (MPS) < muscle protein breakdown (MPB)). Given the capacity of dietary protein to stimulate MPS and inhibit MPB, protein-centered diet interventions have been suggested as countermeasures to muscle disuse atrophy. Manipulating protein intake has been shown to diminish muscle atrophy and/or preserve muscle function in some experimental models of disuse (i.e., immobilization and bed rest in healthy populations) and post-surgical populations. As such, this presentation will consider the potential role of protein-based interventions in mitigating disuse atrophy to accelerate recovery and return to duty in military populations and discuss how such interventions may be incorporated as a standardized component of a Soldier’s treatment and recovery.
