About this study
Official title: Elastic-band Resistance Exercise or Vibration Treatment With Hydroxymethylbutyrate (HMB) Supplement for Sarcopenic Older People
Sarcopenia is a geriatric syndrome characterised by the progressive loss of skeletal muscle mass and function with a risk of adverse outcomes. In Hong Kong, the prevalence of sarcopenia in community-dwelling older people was 9%. According to a meta-analysis on the effect of sarcopenia on health outcomes in older people, sarcopenia significantly increased hazard ratios of falling by 3.23×, functional decline by 3.03× and fracture risk by up to 3.75×, thus making sarcopenia a major risk factor for fragility fractures.
Elastic-band exercise alone was shown to enhance skeletal muscle mass, performance and gait speed. Low-magnitude high-frequency vibration (LMHFV) was shown to be effective in enhancing muscle strength, balancing ability and reducing fall risk. HMB supplementation is advantageous due to its simplicity in administration and found to be effective in maintaining total lean mass, appendicular lean mass, leg and arm lean masses.

The objective of this study is to evaluate the effectiveness of elastic-band exercise or vibration treatment in combination with HMB supplementation on the control of sarcopenia by a single-blinded randomized controlled study.
Community-dwelling older people failing the sarcopenia screening according to the Asian Working Group on Sarcopenia (AWGS) will be recruited and randomized to (1) control, (2) Exercise + HMB or (3) LMHFV + HMB group by envelope drawing of computer-generated random numbers. Control group will be given promotional materials of sarcopenia and will not receive any intervention. The Exercise + HMB group will be instructed to take a thirty-minute home-based elastic band exercise practiced for 30 mins per day, 3 times per week for 3 months. The LMHFV + HMB group will be assigned to participating community centres and receive vibration treatment at 35Hz, 0.3g (peak to peak magnitude), displacement of <0.1mm, for 20 min/day, at least 3 days/week for 3 months. Both HMB treatment groups will given 3.0 g/day for 3 months. Outcome assessments will be performed at baseline and end-point of 3 months. Outcome assessor and statistician will be blinded to group allocation.
Muscle strength in the lower extremity will be the primary outcome. Muscle strength in the upper extremity, gait speed, muscle mass (based on AWGS definition), functional performance in terms of balancing ability and time-up-and-go test, quality of life by short-form 36 will be taken as secondary outcomes.

Sarcopenia is a geriatric syndrome characterised by the progressive loss of skeletal muscle mass and function with a risk of adverse outcomes. In Hong Kong, the prevalence of sarcopenia in community-dwelling older people was 9%. According to a meta-analysis on the effect of sarcopenia on health outcomes in older people, sarcopenia significantly increased hazard ratios of falling by 3.23×, functional decline by 3.03× and fracture risk by up to 3.75×, thus making sarcopenia a major risk factor for fragility fracture.
A recent study reported a randomized controlled trial (RCT) of 3-month intervention of elastic-band exercise alone has shown significant enhancement in skeletal muscle mass by a 0.7 kg gain and a better performance demonstrated by 0.14 m/s faster gait speed. This project targets to investigate the application of elastic-band exercise for older people to carry out at home for sarcopenia intervention.
Low-magnitude high-frequency vibration (LMHFV) has previously shown to be effective in enhancing muscle strength, balancing ability and reducing fall risk in a RCT involving 710 subjects. Community-dwelling older people treated at 35 Hz, 0.3 g and 20 minutes per day for 18-months showed reduced hazard ratio for fall or fracture (HR=0.56, 95% CI at 0.40-0.78, p=0.001), 2.46 kg increase in quadriceps strength (95% CI at 1.70-3.22, p<0.001) and overall statistically significant improvements in balancing ability.
HMB supplementation is advantageous due to its simplicity in administration compared to various other schemes. In a RCT on the efficacy of HMB supplementation on 10-day bed-rested older adults aged 60-76, 3.0-g/day was found to be effective in maintaining total lean mass, appendicular lean mass, leg and arm lean masses with significant differences.
The objective of this study is to evaluate the effectiveness of elastic-band exercise or vibration treatment in combination with HMB supplementation on the control of sarcopenia by a single-blinded randomized controlled study.
Community-dwelling older people failing the sarcopenia screening according to the Asian Working Group on Sarcopenia (AWGS) will be recruited and randomized to (1) control, (2) Exercise + HMB or (3) LMHFV + HMB group by envelope drawing of computer-generated random numbers.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
HydroxymethylbutyrateDietary supplement
Hydroxymethylbutyrate supplementation at 3.0 g/day with dietary advice.
Low-magnitude High Frequency Vibration (LMHFV)Device
Also called Vibration treatment
Low-magnitude High Frequency Vibration is a non-invasive biophysical intervention which provides mechanical stimulation with no reported adverse effects. Our previous studies on bone showed that LMHFV can help boost the patients' bone mineral density (BMD) and muscle health.
Elastic-band ExerciseBehavioural
Subjects enrolled in the elastic-band exercise group will be instructed with 1 session of group training (at baseline) and 1 follow-up home visit (at 4 weeks) including instructions on 5-10 min warm-up and cool-down routines, 30 min chair-based resistance exercises using Thera-Bands as previously reported with training to both upper and lower body muscle groups including both hand and knee extensor muscles. The subjects will be instructed to perform the instructed exercises 3 times per week, one hour after HMB intake, for 12 weeks. The elastic band strengths will be progressively increased from 1.3 kg to 2.1 kg (yellow to green) of tensional force as instructed by a qualified coach in our project team based on each subject's "multiple repetition maximum", where multiple repetition maximum is defined by reaching fatigue by 8 repetitions of stretching.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Sarcopenia is a geriatric syndrome characterised by the progressive loss of skeletal muscle mass and function with a risk of adverse outcomes. In Hong Kong, the prevalence of sarcopenia in community-dwelling older people was 9%. According to a meta-analysis on the effect of sarcopenia on health outcomes in older people, sarcopenia significantly increased hazard ratios of falling by 3.23×, functional decline by 3.03× and fracture risk by up to 3.75×, thus making sarcopenia a major risk factor for fragility fractures.
Elastic-band exercise alone was shown to enhance skeletal muscle mass, performance and gait speed. Low-magnitude high-frequency vibration (LMHFV) was shown to be effective in enhancing muscle strength, balancing ability and reducing fall risk. HMB supplementation is advantageous due to its simplicity in administration and found to be effective in maintaining total lean mass, appendicular lean mass, leg and arm lean masses.
The objective of this study is to evaluate the effectiveness of elastic-band exercise or vibration treatment in combination with HMB supplementation on the control of sarcopenia by a single-blinded randomized controlled study.
Community-dwelling older people failing the sarcopenia screening according to the Asian Working Group on Sarcopenia (AWGS) will be recruited and randomized to (1) control, (2) Exercise + HMB or (3) LMHFV + HMB group by envelope drawing of computer-generated random numbers. Control group will be given promotional materials of sarcopenia and will not receive any intervention. The Exercise + HMB group will be instructed to take a thirty-minute home-based elastic band exercise practiced for 30 mins per day, 3 times per week for 3 months. The LMHFV + HMB group will be assigned to participating community centres and receive vibration treatment at 35Hz, 0.3g (peak to peak magnitude), displacement of <0.1mm, for 20 min/day, at least 3 days/week for 3 months. Both HMB treatment groups will given 3.0 g/day for 3 months. Outcome assessments will be performed at baseline and end-point of 3 months. Outcome assessor and statistician will be blinded to group allocation.
Muscle strength in the lower extremity will be the primary outcome. Muscle strength in the upper extremity, gait speed, muscle mass (based on AWGS definition), functional performance in terms of balancing ability and time-up-and-go test, quality of life by short-form 36 will be taken as secondary outcomes.
