Clinical Trial Summary

Physical inactivity and sedentary time are highly prevalent worldwide and are associated with many adverse health outcomes. Workers adults spend two-thirds of their workday sitting, so they are particularly at risk. Exercise is considered a preventive and treatment tool for diseases, however, the effects of Concurrent Training (that is, aerobic plus resistance training) are not well established in healthy adults. This research project aims to analyze the effects of a concurrent training program on metabolic profile, lung function, stress and quality of life, as well as body composition and physical fitness in sedentary adults. This is a single-blinded two-arm RCT with parallel groups. After completion of baseline assessments, eligible participants will be randomized in a 1:1 ratio to participate in concurrent training group or control group. Repeat assessments will be taken immediately post 8 weeks and post 16 weeks of intervention.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Maximal Dynamic Strength (Estimated 1 RM)	Experimental group participants will perform incremental loading tests to estimated 1 RM in free weights exercises.	Baseline (Week 0) to follow-up (Week 8)
Other	Assessment of Dietary Intake	Dietary habits will be assessed using a semi-quantitative Food Frequency Questionnaire.	Baseline (Week 0) to follow-up (Week 16)
Primary	Change from Baseline in the Lipid Profile at Week 16	The levels of total cholesterol, LDL-C, HDL-C, triglycerides, HbA1c, and glucose will be analyzed. These outcome measures have the same units of measure (mg/dL).	Baseline (Week 0) to follow-up (Week 16)
Primary	Change from Baseline in the Inflammatory Profile at Week 16	The cytokines IL-1ß, IL-1ra, IL-10, IL-6, TNF-a, TGF-ß, adiponectin and leptin will be analyzed. These outcome measures have the same units of measure (pg/ml).	Baseline (Week 0) to follow-up (Week 16)
Primary	Change from Baseline in the Fasting Insulin at Week 16	Insuline will be expressed in mU/L.	Baseline (Week 0) to follow-up (Week 16)
Primary	Change from Baseline in the Blood Pressure at Week 16	The systolic blood pressure (mmHg) and diastolic blood pressure (mmHg) will be measure through an automated oscillometric cuff.	Baseline (Week 0) to follow-up (Week 16)
Primary	Change from Baseline in Salivary Stress Hormones at Week 16	Salivary levels of cortisol, a-amylase, immunoglobulin A, and Lysozyme will be analyzed.	Baseline (Week 0) to follow-up (Week 16)
Primary	Change from Baseline in the Spirometric Values at Week 16	Spirometry will be performed to obtain the Forced Vital Capacity, Peak Expiratory Flow, and Forced Expiratory Volume in 1s.; These outcome measures have the same units of measure, i.e., %predicted.	Baseline (Week 0) to follow-up (Week 16)
Primary	Change from Baseline in the "Satisfaction with Life" at Week 16	The "Satisfaction with Life Scale" questionnaire consists of 5-item formulated in the positive sense, that are answered using a 7-point Likert scale, where 1=strongly disagree and 7= strongly agree. Final scores range between 5 (low satisfaction) to 35 (high satisfaction).	Baseline (Week 0) to follow-up (Week 16)
Primary	Change from Baseline in the "Perceived Stress" at Week 16	The Perceived Stress Scale measures the perception of stress. Seven out of the 14-items are considered negative and seven as positive rated on a 5-point Likert scale. Final scores range between 0 to 56 points, with a higher score representing higher stress.	Baseline (Week 0) to follow-up (Week 16)
Primary	Change from Baseline in the "36-Item Short Form Survey (SF-36)" at Week 16	The 36-Item Short Form Survey is a generic instrument to evaluate health-related quality of life. SF-36 comprises 36 questions that cover 8 domains of health. Response choices for the items were on 2-, 3-, 5- or 6-point scales. Two-component scores are derived from 8 subdomains: a physical component (PC) and a mental component (MC). Higher scores on all subscales represent better health and functioning (>50).	Baseline (Week 0) to follow-up (Week 16)
Primary	Change from Baseline in the "World Health Organization Quality of Life Instruments - Bref" at Week 16	The World Health Organization Quality of Life Instruments - Bref, assesses the subjective quality of life and consists of 26 questions with responses on a 5-point Likert scale. Each domain is made up of questions where the scores vary between 1 and 5. The mean score in each domain represents the perception of the subject of their satisfaction with each aspect of quality of life. The higher the score, the better is their perception. There are no cut-points above or below which quality of life could be classified as "poor" or "good".	Baseline (Week 0) to follow-up (Week 16)
Secondary	Change from Baseline in the Body Composition at Week 16	Body weight (kg) and stature (cm) will be assessed to report BMI in kg/m^2. Values of skeletal muscle mass (kg) and fat mass (kg) will be determined using the tetrapolar bioimpedance (Inbody 270, USA).	Baseline (Week 0) to follow-up (Week 16)
Secondary	Change from Baseline in the Cardiorespiratory Fitness at Week 16	Cardiorespiratory fitness will be assessed by the "Chester Step Test". The maximum test duration is 10 minutes (Level 5). VO2Max will be calculated by the CST software and expressed in mlso2/kg/min.	Baseline (Week 0) to follow-up (Week 16)
Secondary	Change from Baseline in the Muscular Strength at Week 16	Handgrip strength will be measured by Jamar hand dynamometer. The test will be repeated twice with each hand. The score is the highest of the two readings (to the nearest kg).	Baseline (Week 0) to follow-up (Week 16)

Two attempts will be carried out on each side, and the result is the mean of the two measures.; Legs flexibility will be assessed by "Modified Sit-and-reach test". Two measurements will be performed, and the result is the mean of the two measures.	Baseline (Week 0) to follow-up (Week 16)
Secondary	Change from Baseline in the Levels of Physical Activity at Week 16	Sedentary time and physical activity levels (light, moderate and vigorous) will be assessed using a triaxial accelerometer (ActiGraph GT3X, US).; These outcome measures have the same units of measure (min/day).	Baseline (Week 0) to follow-up (Week 16)
