Exercise Program and Diet Intervention Attenuated Inflammation Through Down-regulation of ASC Gene and Inflammatory Markers in Obese Adults
In Brief
A clinical study evaluating Exercise-Diet Intervention and Diet Intervention for Inflammatory Response and 4 related conditions. Completed, enrolled 37 participants across 1 site.
Detailed Summary
Background: Obesity is one of the most important health problems worldwide, several factors related to lifestyle as physical inactivity and unbalanced diets increase their development. This condition is characterized by low-chronic inflammation by excess of adipose tissue. The apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC) protein is part of NLRP3 inflammasome, a complex related to inflammation and metabolic alterations. Purpose: The aim of this study was to evaluate the effect of physical exercise program on ASC gene expression and inflammatory markers in obese adults. Methods: 37 obese individuals were randomized to exercise-diet group or diet-group during a 4-month follow-up period. The dietary evaluation was analyzed by Nutritionist Pro software. Body composition was evaluated by bioimpedance (InBody 370). All biochemical determinations were analyzed by dry chemistry (Vitros 350). ASC messenger ribonucleic acid (mRNA) expression was performed by real-time polymerase chain reaction (PCR) using Taqman probes and by the 2-ΔΔcq quantification method. Cytokine levels was performed using the Bio-PlexPro™ HumanTh17Cytokine Assays (MagPix) panel. Statistical analysis was performed with Statistical Package for the Social Sciences (SPSS) v.22 software.

Interventions
The participants who performed exercise-diet intervention performed an Astrand-rhyming test before and after the exercise program intervention. Participants followed a progressive exercise-program during four months according to initial physical fitness. The main exercises consisted of improving aerobic, speed and resistance performance. During all single sessions, breathlessness and fatigue were measured using 0 to10 Borg scale. A personal trainer certified by American College of Sports Medicine (ACSM) supervised three sessions per week, the other two unsupervised training days the subjects were given the detailed training program to do in house/park. And also, this group received a diet intervention that consisted of a 20 percentage reduction of total energy expenditure estimated by the Mifflin formula with a nutrients distribution as follows: 50% carbohydrates, 30% lipids, and 20% proteins.
