- Brief Summary
The goal of this clinical trial is to \[learn about, test, compare etc.\] in individuals with severe mental disorders and obesity comorbid.
The main question\[s\] it aims to answer are:
* Are inflammatory activity, oxidative and vascular damage and metabolic mechanisms, as well as neurocognitive and functional performance, related to different physical exercise interventions?
* Do inflammatory, oxidative stress and cardiometabolic biomarkers predict neurocognitive improvement after physical activity training?
Participants will guided-exercise of moderate intensity and frecuency, and incentive of autonomous physical activity proposals by the specialist; guided physical activity group (GPAG), or (b) 12 weeks of an exercise program standard physical activity without guided and incentives; standard physical activity group (SPAG).
If there is a comparison group: Researchers will compare GPAG and SPAG to see if inflammatory, oxidative stress, and cardio-metabolic biomarkers improve neurocognitive performance after physical activity training
- Detailed Description
The psychiatric disorders and obesity comorbidity is related to neurocognitive impairment and inflammation. Exercise is crucial to improve and maintain healthy lifestyles. This randomized controlled trial tested the efficacy of aerobic exercise as promoter of neurocognitive improvement across psychiatric disorders and OB comorbid. Participants (n=29) received brief healthy lifestyle counseling and were randomized to 12 weeks of guided-exercise of moderate intensity and frequency, and incentive of autonomous physical activity proposals by the specialist; guided physical activity group (GPAG) (n=10) or 12 weeks of exercise standard physical activity without guided and incentives; standard physical activity group (SPAG) (n=19). Peripheral blood biomarkers of inflammation, oxidative stress, vascular mechanisms and metabolic activity, as well as neurocognitive and functional performance were assessed twice over after and before treatment. Mixed one-way analysis of variance and linear regression analyses were performed.

- Primary Outcome Measures
Name Time Method Systolic pressure/diastolic pressure 4 months Measured on the right arm using an automatic sphygmomanometer with participants in the sitting position after resting for 5 minutes.
Functional Assessment Short Test 4 months Functional performance. The higher scores mean a better outcome.
Verbal learning and memory 4 months Complutense Verbal Learning Test total immediate recall, short-term free recall and long-term free recall The higher scores mean a better outcome.
Cognitive flexibility 4 months Wisconsin Card Sorting Test The higher scores mean a better outcome.
Working memory 4 months Trail Making Test The higher scores mean a better outcome.
Short-term memory 4 months Complutense Verbal Learning Test total immediate recall, short-term free recall and long-term free recall The higher scores mean a better outcome.
Visual memory 4 months Rey-Osterrieth Complex Figure Test figure two minutes after the copy and 20 minutes after the copy.
The higher scores mean a better outcome.World Health Organization Quality of Life brief scale 4 months Quality of life. The higher scores mean a better outcome.
Verbal fluency 4 months Animal naming test for phonemic and semantic fluency. The higher scores mean a better outcome.
Waist circumference 4 months Measured in the standing position at the end of normal expiration and at the midway between the inferior costal margin and the superior border of the iliac crest.
Processing speed 4 months Stroop Color and Word test color/word subtest The higher scores mean a better outcome.
Oxidative stress markers 4 months Oxidative stress in leukocytes was evaluated using fluorimetry techniques with a fluoroscan (Synergy MX). In total, 100 000 cells were plated in each well of 96-well plates and incubated for 30 min at 37 °C with the corresponding fluorochromes, as follows: dichlorofluorescein diacetate to measure reactive oxygen species (ROS) production (485 nm excitation, 535 nm emission), MitoSOX to measure mitochondrial ROS (mROS) (510 nm excitation, 580 nm emission), tetramethylrodamin methyl ester to assess mitochondrial membrane potential (552 nm excitation, 574 nm emission), nonylacridin orange mitochondrial mass (495 nm excitation, 519 nm emission), and 5-chloromethylfluorescein diacetate to measure intracellular glutathione (492 nm excitation, 517 nm emission). The monocyte cell line U-937 was used as an internal control to avoid potential fluctuations in fluorescence over time.
Maximum heart rate 4 months Measured with a watch-shaped device that was worn on the wrist and captured the beats per minute.
Short Form-36 Health Survey questionnaire 4 months Quality of life. The higher scores mean a better outcome.
Metabolic markers 4 months Under aseptic conditions, fasting venous blood samples were collected between 8 and 9 am to measure.
Inflammatory markers 4 months Serum cytokine concentrations were determined using Luminex® X-MAP technology (Luminex Corp., Austin, TX, USA) based on flow cytometry. Sample processing and data analysis were performed according to the manufacturer's instructions. (Behring Nephelometer II, Dade Behring, Inc., Newark, DE, USA)..
Adhesion molecules markers 4 months Serum lipid peroxidation levels were measured using a commercial thiobarbituric acid reactive substances (TBARS) kit according to the manufacturer's instructions (Olympus, Hamburg, Germany). A Luminex 200 flow analyzer system (Austin, TX, USA) was employed to analyze adhesion molecules in serum. To measure immunological markers, citrated blood samples were incubated with dextran (3%) for 45 min to isolate human polymorphonuclear leukocytes (PMNs). The supernatant was layered over Ficoll-Hypaque (GE Healthcare, Barcelona, Spain) and centrifuged for 25 min at room temperature at 650g. Lysis buffer was added to the remaining erythrocytes in the pellet, which were incubated at room temperature for 5 min and then spun at 240g for 5 min. PMNs were rinsed twice and resuspended at 37 ℃ in Hanks' balanced salt solution (Sigma Aldrich, MO). Scepter 2.0 cell counters (Millipore, MA, USA) was employed to count cells
