This 60- minute webinar, hosted by Professor Kevin Tipton from the University of Durham, will look at how nutrition can play a role in the recovery of exercise induced injuries. Certain injuries can result in immobilisation of limbs and/or reduced activity which may lead to loss of muscle mass, strength, and function. Muscle loss with inactivity results primarily from a decrease in muscle protein synthesis and “anabolic resistance,” i.e., a diminished response to stimulation of muscle protein synthesis by anabolic agents - including amino acids from protein intake. Professor Tipton will review why maintenance or even an increase in the amount of protein ingested during periods of reduced activity is an important aspect of nutritional support following injury.
Additionally, inflammatory response to an injury is an integral part of the healing process. Efforts to obliterate inflammation after an injury should therefore be tempered. Instead, avoiding nutrient deficiencies (including energy, protein and micronutrients) should be the key focus of subsequent nutritional support for injuries. Careful determination of energy expenditure and intake during recovery are important aspects of nutritional management.
Professor Tipton will also review the available data for efficacy of nutraceuticals, such as omega-3 fatty acids, leucine, creatine etc., and consider whether nutraceuticals should be considered for preliminary treatment. Aspects of using nutraceuticals for injury support will be discussed, such as optimal dose, timing, and the potentially harmful consequences which are not currently well understood. Finally, Professor Tipton will review the preliminary and indirect evidence for nutritional support for injuries other than those requiring limb immobilisation, such as traumatic brain injuries (concussions) and muscle injuries.
