Historically, sport nutrition research has focused on generating the evidence-base that underpins what nutritional guidelines are provided to athletes (and practitioners). However, practitioners face challenges when implementing such guidelines and there is an absence of evidence in relation to the how. Therefore, questions which seek to advance our understanding of how practitioners implement nutritional recommendations to increase and sustain the systematic update of guidelines into practice, are increasingly being asked. For example, 1) how do athletes experience nutritional adherence in sport? and 2) how do practitioners design and deliver a sport nutrition service which enables athletes’ and sport professionals’ (e.g., S&C coaches, physiologists, physiotherapists, lifestyle advisors, psychologists, coaches, and doctors) behaviours?
It is well established that the application of behavioural science to address complex behavioural problems enables the design and implementation of evidence-based interventions that are targeted and tailored to needs of the group that they intend to serve. Empirical attention to human behaviour in sport nutrition is now gaining traction with the recognition that athletes’ dietary behaviour is influenced by a complex interaction of individual, social, and environmental factors. Therefore, multifaceted sport nutrition programmes are being called for to promote dietary behaviour change.
This collection will present contemporary research on behaviour change in sport nutrition from a behavioural science perspective. We wish to deepen our theoretical understanding of the behavioural science approach in sport nutrition and examine the application of the approach to develop sport nutrition professional practice. With a focus on the behavioural science approach within sports nutrition, we aim to, 1) advance our understanding of behaviour change in sport nutrition; 2) be a catalyst for further research in the area; and 3) provide evidence and theory-informed recommendations for sport nutrition practitioners, researchers, and intervention designers alike.
