Effects of Resistance Training on Sarcopenia in Older Patients With Chronic Heart Failure

Kieu Dang Phuong Nguyen146 enrolled

Overview

The goal of study is to evaluate the effects of an eight-week machine-based resistance training program on managing sarcopenia in older outpatients with chronic heart failure (HF) at Military Hospital 175.

The participants will be randomly assigned to two groups: One group received machine-based resistance training (MRT) at the hospital, while the other group received usual care (US). The outcomes will be measured in the participants after 8 weeks including handgrip strength, gait speed, performance on the five-times sit-to-stand test.

The participants will receive HF treatment as prescribed by cardiologists. If participants have any additional medical conditions, their existing medications or treatments should continue. They are also asked to maintain their usual physical activity, exercise routines, and dietary habits, without making changes outside of the study intervention. At the beginning, patients participating in resistance training should complete a pretest of one-repetition maximum (1-RM) to assess muscle strength, which will be used by a professional physical therapist to develop an individualized prescription. The specific movements are as follows: (1) leg press and (2) calf raise by Proxomed Compass 540 (Germany); (3) leg curl, (4) chest press, (5) push up, (6) seated row by HUR machine (US). During the 8 weeks, subjects will train 3 non-consecutive days/week with intensity 30%1-RM to 60% 1-RM, 3 sets/one excercise with 8-12 repetitions.

Outcomes

Primary Outcomes

The change of muscle strength

The change of muscle strength will be evaluated using handgrip strength, measured in kilograms. Each hand will be tested twice with a Jamar Hydraulic Hand Dynamometer (USA), and the highest value will be recorded.

Time frame: Baseline and 8 weeks

Secondary Outcomes

The change of the five-times sit-to-stand test

The five-times sit-to-stand test is timed in seconds. Participants will sit in a chair without armrests, ensuring their back and lower legs are straight, with their arms crossed over their chest. They will then stand up and sit down as quickly as possible. The time is recorded using a stopwatch, beginning when the participants stand for the first time and ending when they sit down for the fifth time.

Time frame: Baseline and 8 weeks

The change of gait speed

Gait speed is measured in meters per second. Participants will walk at their usual pace over a 6-meter distance, and gait speed will be calculated using the formula v = s/t, where t is the time in seconds and s is the distance (6 meters).

Time frame: Baseline and 8 weeks
