The concept of nutrient timing has been of interest for several years. Before the term was ever coined, athletes were consuming nutrients before and during workouts to aid in fueling for various activities, mainly prolonged bouts of endurance exercise. The science of nutrient timing experienced significant jumps when researchers began to examine how delivery of nutrients impacts resistance-based exercise and how post-exercise delivery altered adaptive signaling pathways, recovery profiles and subsequent performance. From there, science evolved and research questions further examined both acute and prolonged responses to both endurance and resistance-based exercise at delivering various nutrients in varying amounts to identify how these approaches impact how an athlete feels, how they perform, how they recover, and how they adapt to their training. As the literature base of nutrient timing continues to evolve, more research is needed to help scientists, athletes, and practitioners understand how and when nutrient timing should be considered.
Our understanding of pre-workout nutrition on performance, recovery, and training adaptations is far from complete. The goal of this Research Topic is to solicit high-level research investigations that provide new insights into how pre-workout nutrition may impact an individual’s ability to perform, recover, and adapt to all types of exercise training and performance. Very early nutrient timing studies used the pre-exercise period to examine the impact of carbohydrate delivery on metabolic responses and performance, but since that time much focus on nutrient timing has shifted to nutrient delivery during and after training or competition. Ideal articles for this Research Topic will be those studies that have been designed to specifically examine a timing question or use a single or combination of nutrients at one or multiple timepoints. This will help to deepen our understanding of pre-exercise nutrition. Finally, investigations that broaden our understanding of pre-exercise nutrition into non-athletic exercising populations, various athletes, and outcomes of a non-physiological nature will bolster our understanding and help further advance the science of nutrient timing.
The scope of this Research Topic will be centered on Original Research, narrative, systematic, and meta-analysis papers that have examined some novel means by which pre-exercise delivery of nutrients may impact performance, metabolic responses, and recovery. Some key questions articles for this Research Topic can seek to answer include:
• As with many aspects of sport and exercise nutrition, females are largely underexplored and investigations that focus on women are of great interest
• In terms of weight loss and body composition manipulation, can pre-exercise nutrition favorably impact fat loss during a weight loss program or can pre-exercise delivery of certain nutrients afford greater compliance to the mental and physical stress of being in an energy deficit?
• Does pre-exercise nutrient delivery impact how an athlete adapts to training?
• What role does pre-exercise protein and amino acids in combination with macro-, micro- and non-nutrients have on acute exercise performance, affect, etc.?
• Are certain types of exercise or training more suited to yield positive outcomes from pre-exercise nutrition?
• Pre-exercise delivery of what nutrients can impact acute exercise performance?
