Keywords
Breakfast size, Exercise, Cognitive performance, Mood, Appetite, Active women
Brief summary
Both regular exercise and breakfast consumption have well known health benefits. Consuming breakfast prior to morning exercise may influence appetite, mood and cognitive function later in the day. The purpose of this study is to test whether the amount of food consumed at breakfast prior to exercise influences these parameters in active women.
