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.

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 (103 kcal and 8.4 g of protein) in 1 to 2 hours after exercise program.

The only one different between "1 hour combined intervention" and this intervention is the time interval between exercise and nutrition. The time interval of "1 hour combined intervention" is 1 to 2 hour, and this intervention is 2.5-4 hours. Other procedure is totally the same.

Participants only take oral supplement. The oral supplement is the same as the "1 hour combined intervention" and "3 hours combined intervention".

Subjects take oral supplement after exercise in the time period between 1-2 hours. They will take oral supplement during hemodialysis treatment.

All procedures between "1 hour combined intervention" and "3 hours combined intervention" are the same. The only one different is the time interval between exercise and nutrition. In this arm, the time interval of exercise and nutrition is 2.5 to 4 hours. When we recruiting subjects, all interventions will be clearly introduced to them, including the same and the different parts among them.

Subjects only take oral supplement during hemodialysis treatment. The oral supplement is the same as the "1 hour combined intervention" and "3 hours combined intervention".

Measuring whether the of 6-meter walk is less than 1.0 m/s or not. This is one of the sarcopenia indicator.
