About this study
Official title: Effects of Elastic-Band Resistance Training With or Without Breathing Exercise on Pulmonary Function and Functional Performance in Community-Dwelling Older Adults With Pulmonary Function Impairment: A Randomized Controlled Trial
The goal of this clinical trial is to learn whether elastic-band resistance training, with or without breathing training, can improve lung function and physical function in older adults with pulmonary function impairment living in the community. It will also learn about the safety and feasibility of these exercise programs.
The main questions it aims to answer are:
Read more
Does elastic-band resistance training improve lung function, lower-limb muscle strength, walking ability, and exercise tolerance?
Does adding structured breathing training to elastic-band resistance training provide additional benefits for lung function and respiratory-related health status?
Are these exercise programs safe and acceptable for older adults in a community setting?
Researchers will compare three groups: elastic-band resistance training plus breathing training, elastic-band resistance training alone, and usual health education. This will help determine whether elastic-band resistance training is helpful and whether breathing training adds extra benefit.
Participants will:
Take part in a 12-week study
Be assigned by chance to one of three groups
Attend supervised exercise sessions 3 times per week if assigned to an exercise group
Receive usual health education and daily activity guidance
Complete lung function tests, muscle strength tests, physical function tests, and questionnaires at the start of the study, at 6 weeks, and at 12 weeks

Detailed Description
Pulmonary function impairment is common in older adults and may be associated with reduced physical activity, lower exercise tolerance, poorer functional performance, and impaired respiratory-related health status. Community-dwelling older adults with early or mild pulmonary function decline may not receive formal pulmonary rehabilitation, but they may still benefit from simple, low-cost, and feasible exercise-based interventions.
This study was designed to evaluate whether a community-based elastic-band resistance training program, with or without structured breathing training, could improve pulmonary function and functional performance in older adults with pulmonary function impairment. Eligible participants were community-dwelling adults aged 60 years or older who were identified through pulmonary function screening. Participants were randomly assigned to one of three groups: elastic-band resistance training plus breathing training, elastic-band resistance training alone, or usual health education.
The elastic-band resistance training program used progressive resistance exercises targeting upper-limb, lower-limb, and trunk-related functional movement patterns. Training intensity was monitored using a perceived exertion scale and adjusted according to each participant's tolerance and movement quality. The structured breathing training program included breathing control exercises and breathing trainer-based practice, with progression based on training level, breath-holding or maintenance time, repetitions, and perceived breathing effort.
The intervention lasted 12 weeks. Participants in the exercise groups attended supervised sessions three times per week in a community health service setting, while the control group received usual health education and daily activity guidance. Study assessments were conducted at baseline, 6 weeks, and 12 weeks to examine changes in pulmonary function, muscle strength, functional performance, respiratory-related health status, sleep quality, adherence, and safety.
This study may provide evidence for a practical community-based exercise approach for older adults with pulmonary function impairment and may help clarify whether adding structured breathing training to elastic-band resistance training provides additional benefits.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Elastic-Band Resistance Training Plus Breathing TrainingBehavioural
Supervised elastic-band resistance training plus structured breathing training is provided for 12 weeks in a community health service setting. Participants attend 3-5 supervised sessions per week, with at least 3 sessions weekly. Each session includes approximately 60 minutes of elastic-band resistance training, consisting of warm-up, progressive exercises for the upper limbs, lower limbs, and trunk, and cool-down. Intensity is monitored using the OMNI-RES scale and adjusted according to movement quality and tolerance. An additional 10-minute breathing module includes inspiratory and expiratory trainer exercises, diaphragmatic breathing, pursed-lip breathing, rhythmic breathing, and breathing control. Participants also complete about 10 minutes of home-based breathing exercises on non-supervised days. Usual health education is provided.

Questions about this trial
What is this clinical trial studying?
A study testing Elastic-Band Resistance Training Plus Breathing Training and Elastic-Band Resistance Training in people with Respiration Disorders, run by Beijing Sport University at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 30 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
