Clinical Trial Summary

The purpose of this study is to determine whether or not energy and macronutrient intake changes when comparing habitually active and habitually sedentary college-aged males in two different sessions of one resting and one exercise.

Description:

Obesity is a consequence of positive energy balance, in which more energy is consumed than expended. It is hypothesized that regular amounts of physical activity may be important in helping individuals more accurately regulate energy balance. More research is needed to understand the impact of a physically active lifestyle on energy regulation capabilities Therefore, this study looks at sedentary college aged males compared to active college aged males when looking at two different sessions of energy expenditure, one exercise session and one resting session, and their energy and macronutrient intake after these sessions. The sessions will take place in the morning where each participant will exercise or rest and then be allowed to eat from a buffet ad libitum, where acute energy and macronutrient intake will be assessed.

The following hypotheses are proposed:

• Individuals who regularly engage in physical activity will more accurately respond to an energy deficit caused by an acute period of physical activity by increasing intake at a subsequent meal.

• Individuals who do not regularly engage in physical activity (sedentary individuals) will be less sensitive to accurately regulate energy balance and will not respond to an energy deficit caused by a period of acute physical activity.

Intervention

Other:
• Exercise Session
This study consists of two laboratory sessions. Participants will be randomly assigned to the order in which they go through these two sessions. The "Exercise Session" will consist of the participant coming into the lab and completing 45 min bout of exercise on an exercise bike, followed by a 60 min resting period, followed by the lunch buffet portion of the session where they will have 25 min to eat ad libitum.
• Rest Session
This study consists of two laboratory sessions. Participants will be randomly assigned to the order in which they go through these two sessions. The "Rest Session" will consist of the participant coming into the lab and completing a 45 min period of reading followed by a 60 min resting period, followed by the lunch buffet portion of the session where they will have 25 min to eat ad libitum.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Energy Intake at the Meal (Exercise Session)	Energy intake was measured by weighing each item served in the ad libitum buffet meal before and after the subject's meal and subtracting the difference to determine gram weight of each item consumed. Food labels and the NDS-R software were used to determine dietary intake based upon gram weight of each food consumed.	2 hours
Primary	Energy Intake at the Meal (Rest Session)	Energy intake was measured by weighing each item served in the ad libitum buffet meal before and after the subject's meal and subtracting the difference to determine gram weight of each item consumed. Food labels and the NDS-R software were used to determine dietary intake based upon gram weight of each food consumed.	2 hours
Primary	Percent Energy From Carbohydrate at the Meal (Exercise Session)	Carbohydrate intake was measured by weighing each item served in the ad libitum buffet meal before and after the subject's meal and subtracting the difference to determine gram weight of each item consumed. Food labels and the NDS-R software were used to determine dietary intake based upon gram weight of each food consumed.	2 hours
