the Effect of Exercise and Oral Supplement Intervention in Sarcopenia Markers in Hemodialysis Patients

The Effect of Different Post-exercise Oral Nutritional Supplement Intake Timing on Sarcopenia Indicators in Hemodialysis Patients

Objective: To assess the effect of different post-exercise oral nutritional supplement intake timing on sarcopenia indicators in hemodialysis patients.

Study Design: 24-weeks Randomized Control Trial (RCT), includes 12-wk intervention period and 12-week follow up period.

Setting & Participants: Maintenance hemodialysis patients who were older than 20 years old meet sarcopenia diagnosis criteria.

Intervention: Group A: During intervention period, participants have 3 times exercise program per week. Each program is 30 minutes of resistance exercise and aerobic exercise. Participants take oral supplement in 1 to 2 hours after exercise program. Group B: Participants have the same exercise program and oral supplement as Group A. However, they take oral supplement in 2.5-4 hours after exercise program. Group C: Participants only take oral supplement. Control group: Participants maintain usual diet and physical activity without any intervention.
