1. Starvation and Energy Balance
Energy balance determines the positive or negative impacts on lean body mass and functionality during the injured state. Vitals to assess for physiological adaptations to starvation will be discussed. Since fuel utilization can dramatically shift in the underfueled body and ultimately impact treatment outcomes, the clinician should keep a keen eye on energy balance.
2. The Injury Response
The injured state is marked with hormonal features of the stress response. Hypermetabolism, inflammation, and immobility are all aspects during acute and chronic injury and rehabilitation that can be mitigated with nutrition engagement. Physiological changes exacerbate the loss of lean muscle mass during immobilized periods; therefore, preservation of muscle mass becomes a critical control point.
3. Nutrition Considerations for the Injury Response
Infection, soft-tissue injury, and bone injury have unique features causing vitamin and mineral needs to increase above the dietary reference intakes (DRIs). Those needing particular attention include vitamins C and D and the minerals iron and zinc. Other nutrition supplements such as omega-3 fatty acids and creatine can also be beneficial in controlling chronic inflammation while sensitizing the muscle to anabolic stimuli and preventing muscle protein breakdown.
