Metabolic window

The metabolic window is a term used in strength training to describe the 30-minute (give or take, dependent on the individual) period after exercise during which nutrition can shift the body from a catabolic state to an anabolic one. Specifically, it is during this period that the intake of protein and carbohydrates can aid in the increase of muscle mass.[1]

Some theorists believe the metabolic window begins to close within minutes of the end of a workout. The same nutrients taken two hours later result in significantly reduced protein synthesis and muscle glycogen storage.[1] Further research is needed into the effects of food and exercise timing, but methodology has to be considered in these experiments.[2]

Currently there is no scientific evidence to support to the metabolic window theory.
