Blood Flow Restriction Training for Age-Related Sarcopenia

Overview

Brief Title: Safe Exercise for Age-Related Muscle Loss in Hospitalized Seniors Summary: This study compares two exercise methods to help older hospital patients (age 65+) rebuild muscle strength after being diagnosed with sarcopenia (age-related muscle loss). We want to know if using special pressure cuffs during light exercise works better than traditional strength training alone. Who Can Join: Hospitalized seniors with stable health conditions Excludes those with severe disabilities, dementia, or certain blood circulation problems What We'll Do: 40 participants will be randomly assigned to either: Traditional Training Group: Uses weights/bands at 65-75% max capacity Arm/leg exercises 3x/week for 4 weeks Pressure Cuff Training Group: Uses special cuffs on arms/thighs during lighter exercises (20% max capacity) Same exercise frequency with controlled pressure for safety What We'll Measure: Handgrip strength (main test at 0/4/12 weeks) Walking speed, balance tests, quality of life surveys Any side effects like dizziness/nausea Safety First: Doctors will check your health before starting. Nurses will monitor every session. We use medical-grade cuffs with safe pressure limits (arm: 80-100mmHg, thigh: 150-200mmHg). You can stop anytime if uncomfortable. Why This Matters: This could help hospitalized seniors regain strength faster using gentler exercises. All activities are supervised by rehabilitation specialists at West China Hospital, with ethics committee approval (IRB number required).
