The Effects of Intradialytic Aerobic Exercise on Clinical Parameters, Coping With Illness, Perceived Benefits of Exercise and Barriers to Exercise in Haemodialysis Patients: A Randomised Controlled Trial

August 6, 2026 updated by: Muş Alparslan University

THE EFFECTS OF INTRADİALYTİC AEROBİC EXERCİSE ON CLİNİCAL PARAMETERS, COPİNG WİTH ILLNESS, PERCEİVED BENEFİTS OF EXERCİSE AND BARRİERS TO EXERCİSE İN HAEMODİALYSİS PATİENTS: A RANDOMİSED CONTROLLED TRİAL

This randomized controlled trial aims to investigate the effects of an 8-week intradialytic aerobic exercise program on clinical parameters, disease adaptation, and perceived exercise benefits and barriers in patients undergoing maintenance hemodialysis. Eligible participants will be randomly assigned to either an intervention group receiving supervised aerobic exercise during hemodialysis sessions or a control group receiving routine hemodialysis care. Aerobic exercise will be performed three times per week during hemodialysis for eight weeks. Exercise intensity will be individually adjusted according to the participant's subjective fatigue level using the 20-point Borg Rating of Perceived Exertion (RPE) scale, targeting an intensity of 11-13 ("light to somewhat hard"). Outcomes will be assessed before and after the intervention using validated clinical measurements and patient-reported outcome measures.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Dialysis Patient-Perceived Exercise Benefits and Barriers Scale (DPEBBS)
Time Frame: Two months
This is a 4-point Likert scale (1- Strongly Disagree, 4- Strongly Agree). The scale consists of 24 items and two open-ended questions. It comprises five sub-dimensions: "Daily Life (7 items)", "Exercise-related Undesirable Outcomes (7 items)", "Quality of Life (4 items)", "Exercise Effects (3 items)", and "Exercise Benefits (3 items)". The daily life and exercise-related undesirable outcomes sub-dimensions represent the obstacles to exercise, while the quality of life, exercise effects, and exercise benefits sub-dimensions represent the benefits of exercise. Items 3, 4, 6, 7, 10, 13, 16, 20, 22, and 23 comprise the benefits sub-dimension; items 1, 2, 5, 8, 9, 11, 12, 14, 15, 17-19, 21, and 24 comprise the obstacles sub-dimension. The items in the DPEBBS scale that represent barrier factors are reverse-coded. The scale is evaluated based on a total score (min=24, max=96). Higher scores indicate a greater perception of exercise benefits and fewer exercise barriers.
Two months
The End-Stage Renal Disease Adherence Questionnaire (ESRD-AQ)
Time Frame: Two months
The scale, designed to assess adherence to end-stage renal failure, consists of nine questions and four sub-dimensions encompassing adherence behaviors: "hemodialysis participation," "medication adherence," "fluid restriction adherence," and "diet adherence." The total score obtainable from the scale ranges from 0 to 1200. Higher scores indicate higher adherence to treatment.
