About this study
Official title: Effect of Activity at the Ventilation Threshold on Appetite and Food Intake After a Glucose Drink in Normal Weight, Overweight and Obese Boys
The investigators hypothesize exercise increases short term appetite and food intake, and interferes with satiety and satiations to a preload in normal weight, overweight and obese boys.
Read the detailed description
The effect of exercise (EXR) on short-term food intake (FI) and subjective appetite was investigated in normal weight (NW), overweight (OW) and obese (OB) boys were randomized into 4 treatments. Each boy consumed either a non-caloric sweetened control (CON) or GLU drink after either exercise (EXR) or sedentary activity. Subjects exercised at their ventilation threshold (VeT).

Detailed description
The effect of exercise (EXR) on short-term food intake (FI) and subjective appetite was investigated in normal weight (NW), overweight (OW) and obese (OB) boys were randomized into 4 treatments. Each boy consumed either a non-caloric sweetened control (CON) or GLU drink after either exercise (EXR) or sedentary activity. Subjects exercised at their ventilation threshold (VeT).

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
food intake (kcal) (time frame: at 30-35 min after the treatment). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01196351, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
