Feasibility and Benefits of Group Based Exercise in Residential Aged Care Adults: a Pilot Study for the GrACE Programme
This study is a pilot study (feasibility and acceptability study), which will compare feasibility and efficacy outcomes between a 12-week Exercise Program and control group in RAC residents.
Study Design and Recruitment This study compared the delivery feasibility and outcomes of a 12-week combined resistance and weight bearing exercise programme which the investigators named the GrACE programme. Participant recruitment and assessment occurred over a five-month period.
The RAC was approached about participation via email and telephone follow-up. Potential participants were identified at a meeting with the facility Service Manager. Participants were screened via the inclusion criteria at the meeting with the Service Manager and a Registered Nurse, and written consent was attained prior to participation. Following an explanation of the procedures, purposes, benefits and associated risks of the study, participants had the opportunity to ask questions. A total of 37 older RAC adults provided written informed consent for the study. The exercise group contained 20 participants and the control group 17 participants. Ethical approval to conduct this study was attained from Bond University's Human Ethics Research Committee (RO 1823).
Intervention: the GrACE programme Previous work by our group trialled a successful exercise programme in respite day care that could promise benefits to those in RAC (HenwoodWooding & de Souza 2013). In brief, the GrACE programme included a number of targeted weight-bearing exercises (using body weight and dumbbells) and a range of seated, non-resisted upper- and lower-body dynamic and reaching movements. While developed for respite care older adults, the programme was slightly modified for the RAC setting; initially using reduced range of motion and resistance, and an extended conditioning/familiarisation phase. The conditioning phase lasted for three weeks in which technique was emphasised without using any weights or additional resistance. The focus of this technique of the conditioning phase was to develop the correct technique and minimise the potential for any delayed onset muscle soreness or adverse effects. After concluding the conditioning phase, participants were able to use light dumbbells (often starting with 0.5kg) increasing to heavier dumbbells (up to 4kg) with their increasing capacity over the course of the programme. Participants performed the exercises twice per week for 12 weeks. Training sessions lasted approximately 45 minutes, were separated by at least 48 hours and were delivered by an allied health professional experienced working with RAC adults.
Control Group All subjects assigned to the control group were given the option to engage in other activities that were offered by the facility during the 12-week intervention period. Activities were facility specific, and included Zumba Gold aerobic exercise and walking, however no specific resistance exercises were offered.
Data Collection Reasons for refusal (non-consent) to participate were recorded (Henwood 2014). All muscle function outcome measures in this study have been previously validated for use with older adults, and their protocols reported elsewhere (Henwood, Wooding & de Souza 2013; Sterke et al. 2012). Assessments were completed one-on-one with each participant. During muscle function measures assessments, participants were encouraged to rest as needed and given verbal support and encouragement to reduce any potential burden to the participant.
