When a sports nutrition coach cannot find a randomized trial, what might they refer to for insights?

In situations where a randomized trial is unavailable, a sports nutrition coach might turn to a case study for insights. Case studies provide detailed examinations of individual or group experiences and can offer valuable perspectives on specific dietary interventions or nutritional strategies implemented within real-world contexts. By analyzing these unique situations, coaches can glean practical insights that might not be captured in larger-scale studies. Although case studies may not provide the same level of generalizability as randomized trials, they can still highlight trends, outcomes, or effective practices that are relevant to particular populations or scenarios.

While peer-reviewed literature typically encompasses a broader range of studies and includes both randomized and non-randomized research, it may not always provide the individual-level insights that a case study does. Cohort studies can also offer useful information but are generally more focused on larger groups and trends over time rather than specific individual cases. Expert opinions may provide guidance but are subjective and lack the empirical foundation found in case studies. Thus, a case study serves as a valuable resource when randomized trials are not available.
