The Effect of Breakfast Size Prior to Morning Exercise on Cognition, Mood and Appetite in Habitually Active Women

The Effect of Breakfast Size Prior to Morning Exercise on Cognition, Mood and Appetite Later in the Day in Habitually Active Women

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Cognitive function change from baseline scores	Participants will complete 4 cognitive tasks (Four Choice Reaction Time, NBack, Stroop and RVIP) measuring reaction time, short-term memory, speed of processing and attention.	Assessed hourly until 4.5 hours and at 6.5 and 10.5 hours

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Mood change from baseline scores	Mood will be assessed using Visual Analogue Scales (VAS) immediately before and after each set of cognitive tasks.	Assessed hourly until 4.5 hours and at 6.5 and 10.5 hours

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Appetite change from baseline scores	Appetite will be assessed using Visual Analogue Scales (VAS) immediately before each set of cognitive tasks.	Assessed hourly until 4.5 hours and at 6.5 and 10.5 hours
