EaRneST: Exercise and CiRulating MetabolomicS: A Pilot Randomized Controlled Study

Brief Summary

Detailed Description

Detailed Description The purpose of the study is to determine the effect of a structured exercise intervention on mitochondrial fuel metabolism and cardiovascular function. Participants with diastolic dysfunction will undergo a structured exercise intervention. Group A (intervention) will undergo exercise intervention for three months and Group B (control) will not receive the exercise intervention. At the start of the study and upon completion, all participants will undergo cardiovascular tests to measure cardiovascular function, as well bio-specimen (blood and urine) collection for metabolic profiling. Study Design Study Type : Randomized controlled trial Estimated Enrollment :40 participants Time Perspective:Prospective Official Title:EaRneST: Exercise and CiRculating MetabolomicS: A Pilot Randomized Controlled Study Study Start Date :July 2018 Estimated Primary Completion Date :Nov 2019 Estimated Study Completion Date : Nov 2019 Groups and Cohorts Group/Cohort :Group A Intervention/treatment Visit 1. Baseline procedures 1. Cardiovascular measurements Arterial stiffness assessment by non-invasive brachial blood pressure machine Echocardiography Standard transthoracic echocardiographic examination will be performed according to established laboratory practice using standard commercially available machines. Resting electrocardiography will be performed to ascertain sinus rhythm. 2. Biospecimen collection Fresh blood, urine specimens will be collected for metabolomics. 3. Six-minute walk test The Six-Minute Walk Test is a shuttle walk test. 4. Musculoskeletal Analysis Participants will undergo focused examinations that include measurement of height, weight, body mass index, waist circumference, body composition analysis.
