Yoga vs. Stretching-Strengthening: Physical Fitness in Sedentary Young Adults

Turkey (Türkiye)50 participantsStarted 2026-06-22

Plain-language summary

The goal of this clinical trial is to learn if yoga or stretching-strengthening exercises are more effective in sedentary young adults who are currently healthy but at risk due to inactivity. The main questions it aims to answer are: Which exercise type leads to better improvements in physical fitness, mental well-being, and sleep quality based on a person's starting profile? How do initial levels of balance and muscle strength affect how well a person responds to these exercises? Researchers will compare a yoga group to a stretching-strengthening exercise group to see if one approach is more effective than the other for specific types of individuals. Participants will: Be evaluated for their starting physical fitness (balance and strength) and psychological health. Perform either yoga or stretching-strengthening exercises regularly during the study period. Complete surveys about their mood, stress levels, and sleep quality. Be re-tested at the end of the program to measure changes and improvements.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1This trial compares yoga to stretching-and-strengthening exercises for sedentary young adults — given my current activity level and health history, which of these two approaches do you think would be safer or more appropriate for me to start with?
2Since this trial isn't recruiting yet, is it worth waiting to see if I'm eligible once it opens, or would you recommend I start some form of structured exercise program now rather than delay?
3The trial measures things like muscle strength, core endurance, flexibility, and balance — are there any of these areas where you have specific concerns about my baseline fitness that I should know before joining a structured exercise study?
4This study is listed as Phase NA, which I understand means it's more of a behavioral or fitness comparison than a drug trial — does that change the kinds of risks I should think about, and are there any physical conditions I have that might make either yoga or strengthening exercises risky for me?
5If I don't end up qualifying or the trial never opens near me, are there evidence-based yoga or stretching-and-strengthening programs you'd recommend that target the same fitness goals this study is measuring?

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
