Foundational evidence from this study will provide insights into the feasibility of the digital approach.
#Sequential multiple assignment randomized trial trial#
Discussion: This study will be the first to investigate improving carbohydrate periodization using a digital approach and tailored coaching strategies under this context. A sequential multiple assignment randomized trial (SMART) is an experimental design that scientists can use to develop highquality dynamic treatment regimens (DTRs), a prespecified. Due to the high attrition nature of digital interventions, all quantitative analyses will be carried out based on both the intention-to-treat and per-protocol principles. Secondary outcomes are changes in goal, weight, carbohydrate periodization self-efficacy, and beliefs about consequences. The primary outcomes are the mobile application and coach uptake, retention, engagement, and success in attaining carbohydrate periodization behavior. In the SMART, athletes will be given the application and additional coaching according to their engagement responses. We will then conduct a 4-week pilot sequential multiple assignment randomized trial (SMART) with an additional 150 athletes. SMART COMPASS is pragmatic, mirroring clinical, antibiotic-treatment decision-making and addressing the most relevant issue for treating patients: identification of the patient-management strategy that optimizes the. 250 athletes with pre-existing nutritionist support will also be recruited as control. Sequential, multiple-assignment, randomized (SMART) COMPASS allows evaluation when there are multiple, definitive therapy options. 500 athletes will be recruited to test the feasibility of a novel menu planner mobile application with coaching for 6 weeks. Methods/design: We aim to recruit 900 athletes across the UK. Yet, digitally delivered dietary behavior change interventions for athletes and the coaching strategy to support them are still novel concepts within sports nutrition. Digital environments appear to allow nutritionists to deliver this intervention at scale, reducing expensive human coaching time. Despite this approach being accepted in the athletic populations, athletes do not systematically follow the guidelines. See Sequential multiple assignment randomized trials (SMART) design. Background: It has recently been identified that manipulating carbohydrate availability around exercise activity can enhance training-induced metabolic adaptations. inference based on p-values, non-sequential case mean-unbiased estimate.
