Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Progressive Resistance Training - two one hour group sessions per week for 24 weeks with a 24 week follow-up period.
Participants will undertake twice weekly machine-based resistance and free standing balance training for 24 weeks under the close supervision of accredited exercise physiologist experienced in delivery to older adults with complex health care needs.

Sessions will be preceded by a low intensity five minute warm-up using ergonomic walking, arm or leg cycling, or rowing machines, and followed by a five minute warm-down that includes targeted stretching. Within each session participants will undertake six resistance exercises using air-pressure driven machines proven effective in older disabled adults (HUR Australia) and balance exercises targeting static and dynamic balance, and agility.
To ensure technique development and reduce training related delayed on-set of muscle soreness (DOMS), participants will undertake a four week conditioning phase prior to training at a higher-intensity. Specifically, for the first two weeks participants will
complete 3 sets of each exercise for 8 repetitions at 50% of the predicted maximum capacity.
For the third and fourth week of training the intensity will be increased to
65% but set and repetition kept the same.

From the fifth week, the intensity will be increased to 75% of the participants predicted maximum capacity. The predicted maximum will be a conservatively assumed resistance based on the participant’s ability to complete repetitions. At the highest intensity, an accurate resistance will be reflected by the participant’s capacity to complete eight repetitions before fatigue.
Isometric extension measurements are recorded fortnightly for each of the participants to measure their performance improvement and as an indicator of global body strength and functional capacity.
Each participants provided with a swipe card that automatically uploads their individualised routine onto each of the six exercise stations. This also allows for instant tracking of attendance to the session, adherence (using all six stations), and performance (under, on or over).

Rehabilitation
Comparator / control treatment
Wait list control. Participants entering this group will be asked to continue with their usual care for an initial 24 week period. Within this time period there will be no restriction on receiving allied health services, attending activity groups or any other physical activities they are presently receiving or involved in. However, participants will be asked not to commit to or become involved in any new ongoing (> 1 session) activity groups that they are not referred to by their GP or specialist.
At the end of the 24 week waiting period this group will enter the intervention group.

Measured at baseline, 24 weeks of intervention and 24 weeks follow-up
Secondary outcome [1] 317649 0
Economic benefit (this is a primary outcome)
Measured by modelling the:
(1) incremental cost-effectiveness of clients provided this PRT model compared to those receiving usual care. Cost will include health service utilisation costs, capital costs, overheads and transport costs. Effectiveness will be measured using the changes in primary outcomes between the two trial groups (exercise and waiting list).
(2) Cost -utility measured using the EQ-5D to derive a cost per Quality Adjusted Life Year (QALY). Costs will be those of health service utilisation costs, capital costs, overheads and transport costs. and client costs attributable to the program (e.g. self transport, memberships, opportunity costs).
(3) Cost-benefit measured from the perspective of Australian society. Costs again derived from Health service utilisation, capital costs, overheads, transport costs, client costs, opportunity costs, transfer costs. Benefits will be expressed in dollars ($AUD) over a time horizon of two years and will include reduced health care utilisation, delay entering residential aged care, improved participation/productivity and a willingness to pay determination.
Timepoint [1] 317649 0
Effectiveness and QoL data collected at baseline, 24 weeks of intervention and 24 weeks follow-up.
Cost data collected daily through diary completion, trip logs and project expenses.
Willingness to pay and qualitative information informing social benefits/costs of the program collected at dropout, 24 weeks of intervention and again at follow-up.
Secondary outcome [2] 318209 0
Sarcopenic Status: Diagnosis of sarcopenia requires the presence of both low muscle mass and low muscle function (strength or performance).
Muscle mass will be measured by BIA, muscle strength by hand grip strength, and performance by the SPPB 2.4 metre walk. The established cut-off points to define low muscle mass are less than or equal to 2 standard deviations below the norm of a young healthy population (less than 8.87 kg/m2 for men and less than 6.42 kg/m2 for women), for low muscle strength less than 30 and less than 20 kg for men and women, respectively, and low muscle performance a gait speed of less than 0.8 m/s. In addition to the physical assessment of sarcopenia, the SARC-F questionnaire will be complete as an assessment of tool validity in the target population and an Australian context and the FRAIL scale will be used to investigate relationships between sarcopenia and frailty.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Potential participants are invited to apply and are screened for inclusion and exclusion criteria using a checklist by the project manager.
At baseline assessment eligible participants are provided with a unique identifying number by the exercise physiologist (who are assessing them) and who are blind to the allocation sequence.
The allocation sequence was computer generated by one of the investigators at a separate site prior to the assessment period.
The Project Manager then looks up the allocation sequence and matches the allocation to the unique identifying number provided to the participant.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A list of consecutive Study IDs is assigned to one of the two groups in 2:1 (control:intervention) ratio using computerised random allocation in blocks..

Statistical methods / analysis
The sample size is based on a feasibility of delivery capacity calculation accounting for 5 participants per session training twice weekly for 24 weeks at 2 location supervised by 2 exercise physiology staff, with delivery occurring in waves. Session numbers will be increased among higher functioning participants as the project progresses and AEP gain experience with the delivery.
A power calculation was not conducted.
The primary analysis will be of individual participants’ data in the exercise versus the wait list control group, adjusted for group baseline differences. The analysis will include:
1) Repeated measures on the quantitative outcome measures between groups at the intervention two time points. A secondary within exercise group analysis will explore what if any residual impact of training was present during the follow-up period.
2) An exploratory analysis using regression analysis will look at relationship between key variable in disability and health care utilisation to identify risk factors.
3) Health economic modeling will be between the cost of intervention delivery and usual care base on Australian dollars.

Summary
Brief summary
Progressive resistance training (PRT) is a powerful but underutilised tool in the battle against later life disability. With regular and ongoing PRT older adults can reduce their decline into dependency and disability. This has important implication for an individual's quality and dignity of life and for the national healthcare budget.

The primary objective of this project is to evaluate evidence-based PRT as a service delivery option for community-dwelling older adults receiving government subsidised home care assistance. A comparison will be made between PRT participation and wait list control participants.

Given the strength of evidence we hypothesise that with regular PRT, participants will reduce their trajectory of health decline, improve and prolong their wellbeing, with benefits retained for up to 24 weeks after the training period.

Three hundred adults 65 years and older residing in north Brisbane and receiving a government subsidised home care assistance will be randomised to twice weekly PRT or a wait list control group. Participants will be bussed to and from their training and assessment sessions. All assessments and training session will be supervised by accredited exercise physiologists with special population expertise in disability and gerontology prescription.

Data will be collected prior to and following long-term participation (24 weeks), and following a long-term period of non-participation (24 weeks), so the residual impact of PRT can be evaluated.
