Sarcopenia and Combined-modality Exercise

Not Applicable

Terminated

• Conditions: Sarcopenia

• Registration Number: NCT04806152
• Lead Sponsor: The University of The West Indies

Brief Summary

This study examined the effects of combined-modality exercise training (resistance, endurance, flexibility and balance) on muscle mass, muscle function and physical activity in community-dwelling elderly living in Jamaica who had been characterised as having sarcopenia.

Detailed Description

Community-dwelling seniors aged 60 years and older were screened for muscle mass and function (grip strength and walk speed) and persons with sarcopenia were identified using the European Working Group on Sarcopenia in Older Persons (EWGSOP) algorithm for case finding (N=1344). Of the 77 seniors with sarcopenia, 38 consented to participate and were randomly allocated to receive 6 months combined-modality high intensity treadmill based exercise and a 'usual care' home exercise programme. A comparison of the effects of treatment assignment on muscle mass, function, fitness, physical activity level and disability was done. Participants in the supervised combined-modality high intensity group were required to attend sessions 3 times per week; participants in the home exercise programme were required to attend 1 supervised session at the start of their 6-month intervention. Outcomes were assessed at baseline and at the end of the 6-month intervention. Data were analysed using standard statistical parametric and non-parametric methods including repeated measures analysis of variance to determine changes in outcomes and regression to establish determinants of outcomes.

Primary Outcome Measures

Name	Time	Method
Lower extremity (LE) functional strength	6 months	1-repetition maximum (RM) strength
Appendicular lean mass index	6 months	dual energy x-ray absorptiometry (DEXA) measured appendicular lean mass summed and divided by height squared, expressed in kg/m2
Disability	6 months	Lawton Instrumental Activities of Daily Living scale: minimum score = 0 (low function, dependent); maximum score = 8 (high function, independent). Lower scores indicate a worse outcome.
Fat-free mass	6 months	dual energy x-ray absorptiometry (DEXA) determined: fat mass subtracted from weight, expressed in kg
self-selected walk speed	6 months	speed in the timed-10-metre walk
Accelerometry	6 months	weekly energy expenditure
Balance	6 months	Berg balance test score: minimum score = 0, maximum score = 56. Lower values indicate worse outcome
Functional endurance	6 months	Distance walked in 6 minutes

Secondary Outcome Measures

Name	Time	Method
Depression	6 months	Center for Epidemiological Studies-Depression \[CES-D\] score: minimum score = 0, maximum score = 60, with higher scores indicating more depressive symptoms
Timed-up-and-go	6 months	Functional test indicating fall risk
