New study tests blood flow cuffs to boost leg strength in seniors
NCT ID NCT07534150
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether combining blood flow restriction (BFR) with resistance training can improve leg muscle function in older adults with dynapenia (age-related muscle weakness). Researchers will measure muscle strength, body composition, and physical performance in 720 participants aged 55 and older. The goal is to find the best BFR exercise settings and see if a 4-month training program helps participants regain strength and maintain it over time.

Inclusion Criteria * Aged 55 years and older. * No regular physical activity within the past three months, defined as exercising no more than twice per week. * No cognitive impairment and able to follow exercise and assessment instructions. Exclusion Criteria * Have contraindications to exercise, such as severe musculoskeletal problems, osteoporosis, deep vein thrombosis, or coagulation disorders. * Have comorbid conditions that are severe or end-stage, such as stroke diagnosed by a neurologist, diabetes with severe complications (e.g., retinopathy), or cardiovascular disease including heart failure, coronary ischemia, or arrhythmia. * Have high-risk factors for exercise, such as uncontrolled hypertension (systolic blood pressure \>160 mmHg or diastolic blood pressure \>100 mmHg), angina or chest tightness during exercise, or deep vein thrombosis. * Have a history of hematologic disorders or are currently taking blood-related medications, such as hormones or anticoagulants. * Are expected to move out of the local community within three months.
