The Comparison of Energy in Take & Body Weight EXERCISE

Status Completed

Clinical Trial Summary

This study will compare the effect of two doses of exercise on energy intake and body weight. The comparison will be between three groups; two exercise groups and a control group. The exercise groups will not be provided with a dietary intervention and the study design also includes a non-exercise control group. E-Mechanic trial can make important contributions to understanding of the role of exercise dose in weight management. While it is accepted that regular exercise plays an important role in general health, the exact role of exercise in prevention of weight gain, weight loss and prevention of weight regain remains poorly understood despite exercise being widely prescribed for these purposes. The idea that current weight management exercise recommendations may produce increased energy intake (or other forms on compensation) resulting in disappointing weight loss is an important public health issue. The finding of this study could help shape future exercise and weight loss recommendations and treatment plans.

Clinical Trial Description

The purpose of the E-MECHANIC Trial is to test the effect of two doses of exercise on energy intake, body weight, body composition, activity levels, and metabolic rate. The exercise doses will reflect current recommendations for: 1) general health (8 KKW), and 2) weight loss (20 KKW). A non-exercise control group will also be recruited. The primary outcome variables are: 1) energy intake, and 2) the discrepancy between expected weight loss and observed weight loss. Energy intake will be measured using doubly labeled water and laboratory-based food intake tests. Secondary outcome variables include resting metabolic rate, activity levels (excluding structured exercise), and body composition. Following a comprehensive baseline assessment, participants will be randomly assigned to the 8 KKW, 20 KKW, or control group in a 1:1:1 ratio. Additional assessments will be conducted at week 4, with another comprehensive assessment at week 24. The week 4 assessment is important to determine if endpoints change in the short-term, but not long-term. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
