Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

With many medications we prescribe them relative to time of day or a meal. This study established if pre dinner vs post dinner exercise was more effective at altering post dinner glucose and triglyceride levels vs no exercise at all.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

All participants completed three trials in a random order in which they consumed a standardized dinner meal with 1) no RE (NoRE), 2) pre-dinner RE (RE→M), and 3) post-dinner RE beginning 45 min after dinner (M→RE). Diet was standardized during the day of testing. Participants reported to the lab for testing sometime between 3 - 5:30 p.m. and upon arrival a venous catheter was inserted into a forearm vein. Frequent blood sampling, indirect calorimetry measurements, and subjective well-being measurements ensued for \~5.75 h while the participants were in the lab.
