Brief Summary

In the past few years, Branched Chain Amino Acid (BCAA) supplements have gradually used on different groups. From training athletes, maintaining functions of healthy elders to preventing disabilities of people that can't do intense exercises. BCAAs are now considered to be able to prevent muscle atrophy and strength loss, also possible to increase strength and muscle mass if combined with resistance exercises. Stroke patients have difficulties with moving, which led to multiple disabilities, are more likely to have sarcopenia and strength loss. Furthermore, reducing the will of moving or walking. Recently, studies showed that combined BCAAs with resistance exercises can effectively increase muscle mass, thus commonly used on training athletes. Although aerobic exercises are proven to be more likely to improve walking ability of chronic stroke patients than traditional rehabilitation, BCAAs' effects are yet to be proven. Therefore, the aim of this study is to explore if BCAAs combined with moderate intensity exercises can prevent muscle atrophy, loss of strength and cardiopulmonary function. This is a randomized control trial. Participants are randomly assigned to either experiment or control groups. Both group received aerobic exercise (30 min in a session, 3 days a week, and for 8 weeks). Experiment group received BCAA supplement immediately after the exercise while the control group receive sham product (vitamins). The outcome measurements (including muscle mass, functional measures, and quality of life) are performed before (0-wk) and after (8-wk) the interventions, also after interventions in 3 months and 6 months for follow up.

Study Arms (2)

BCAA group

EXPERIMENTAL

Participants in the BCAA group take 40g of BCAA supplement before each aerobic exercise session. The interventions include 24 aerobic training sessions. Accordingly, the participants intake 960g of BCAA during a 8-week intervention period.

Dietary Supplement: BCAA supplementOther: Aerobic exercise

Control group

PLACEBO COMPARATOR

Participants in the control group take 40g of placebo before each aerobic training session. The placebo has the same caloric as the BCAA supplement but with different constitution (eg, different percentage of protein, fat and carbohydrate)

Dietary Supplement: BCAA supplementOther: Aerobic exercise

Interventions

BCAA supplementDIETARY_SUPPLEMENT

Before each exercise session (described later), the research assistant will give subjects 40g of BCAA or placebo supplement according to the treatment assignment and ask them to drink it down right away.

BCAA groupControl group

The exercise intervention includes 24 aerobic stationary cycling sessions (30 min/session, 3 session/week, and 8 weeks). The exercise sessions proceed under the supervision and guidance of a therapist.
