High-Intensity Interval Resistance Training and Low-to-Moderate-Intensity Resistance Training in Upper Extremity Muscles

Turkey (Türkiye)49 participantsStarted 2026-05-18

Plain-language summary

High-intensity interval resistance training (HIIRT) has emerged as a time-efficient alternative to conventional resistance training; however, evidence regarding upper-extremity-focused HIIRT and its multidimensional effects remains limited. This randomized controlled trial aims to compare the effects of upper-extremity HIIRT and low-to-moderate-intensity resistance training (LMRT) on muscle strength, functional capacity, cognition, mental health, and health-related quality of life in healthy young adults. Forty-nine healthy young adults aged 18-25 years will be randomly allocated to one of three groups: HIIRT, LMRT, or a control group. Participants in the intervention groups will complete supervised upper-extremity resistance training sessions twice weekly for 8 weeks, while the control group will receive no structured exercise intervention. Outcome measures will include isotonic upper-extremity muscle strength, the Six-Minute Walk Test, the Montreal Cognitive Assessment, the State-Trait Anxiety Inventory, the Generalized Anxiety Disorder-7 questionnaire, the Dispositional Flow Scale-2, and the Short Form-36 Health Survey. The study is designed to evaluate the effects of the two resistance training protocols on physical, cognitive, and psychological outcomes in healthy young adults.

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.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

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.
