Abstract

Over the last decade, in support of training periodization there has been an emergence around the concept of nutritional periodization. Within athletics (track and field), the science and art of periodization is a cornerstone concept with recent commentaries emphasizing the underappreciated complexity associated with predictable performance on demand. Nevertheless, there are numerous training, with varying levels of evidence, that feature sport and event specific purposeful sequencing of different training units [long (macro-cycle; months), medium (meso-cycle; weeks) and short (micro-cycle; days and within-day duration] training cycles and sessions. Indeed, implementation of strategic temporal nutrition interventions (macro, meso and micro) can support and enhance training prescription and adaptation, as well as acute event specific performance. However, a general framework on how, why and when nutritional periodization could be implemented has not yet been established. It is beyond the scope of this review to highlight every potential nutritional periodization application. Instead, this review will focus on a generalized framework, with specific examples of macro-, meso- and micro-periodization for the macronutrients of carbohydrate (CHO), and by extension fat. More specifically, we establish the evidence and rationale for situations of acute high CHO availability, as well as the evidence for more chronic manipulation of CHO coupled with training. The topic of periodized nutrition has made considerable gains over the last decade, but is ripe for further scientific progress and field application.
