Concurrent Training and Metabolic Profile, Lung Function, Quality of Life and Stress
Effects of Concurrent Training on Metabolic Profile, Lung Function, Quality of Life and Stress in Sedentary Adults: A Randomized Controlled Trial
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.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Concurrent Training Group
The experimental group will perform 16-weeks of the concurrent training exercise.

|
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)
|
Change from Baseline in Salivary Stress Hormones at Week 16
Time Frame: Baseline (Week 0) to follow-up (Week 16)
|
Salivary levels of cortisol, α-amylase, immunoglobulin A, and Lysozyme will be analyzed.
|
Baseline (Week 0) to follow-up (Week 16)
|
Change from Baseline in the Spirometric Values at Week 16
Time Frame: Baseline (Week 0) to follow-up (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)
|
Change from Baseline in the "Satisfaction with Life" at Week 16
Time Frame: Baseline (Week 0) to follow-up (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)
|
Change from Baseline in the "Perceived Stress" at Week 16
Time Frame: Baseline (Week 0) to follow-up (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)
|
Change from Baseline in the "36-Item Short Form Survey (SF-36)" at Week 16
Time Frame: Baseline (Week 0) to follow-up (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).

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".
