This study aims to test which of three exercise programs, previously demonstrated valuable for residential aged care adults, has the greatest benefit for walking speed and the spatiotemporal parameters that define it. The programs to be included are: 1. The GrACE program and 2. The GrACE plus Gait specific training.
This study will employ a non-randomised controlled design in which three different 24-week exercise programs and a non-exercising control group will be compared in the residential aged care (RAC) setting. The three programs are the GrACE and the GrACE plus a gait specific training program. Data Collection \~40 participants from two RAC facilities will be recruited into the study. This number of participants will provide 80% statistical power to identify moderate effect size between group differences on the primary outcome measures. The control group will be drawn from each of the RAC facility approached receiving exercise treatment. Participation will be informed by a discussion with the facilities Service Manager about the eligibility of participants and a medical history screen undertaken. All participants will provide informed written consent prior to participation. Participants in the exercise group will perform twice weekly training for 24 weeks. Data will be collected at 0 weeks, 12 weeks and 24 weeks in the control and exercise groups.

Gait speed and spatio-temporal parameters (in a wider variety of walking tasks)
Gait speed and spatio-temporal parameters will be recorded via the GaitMat II system (Manufacturer is EQInc; Model is GaitMat II), which required participants to walk across a level pressure mat system 3.66 m (11.91 ft.) long (McDonough et al. 2001). Participants completed the trials at their preferred (habitual) walking (gait) speed. All measures will be initiated from a standing start 2 m (6.56 ft.) from the GaitMat II platform as suggested by Kressig and Beauchet (Kressig \& Beauchet 2006) to reduce the effect that acceleration may have on gait speed. Three conditions will be measured which include normal walking, along with two dual tasks. These dual tasks include: (i) walking while carrying a glass of water in the participants preferred hand, (ii) walking while counting backwards from 30. Each of these gait conditions will be performed for three repetitions in a randomised block order (Taylor, 2012).

Sit to stand performance
In the sit-to-stand measure, participants sat and stood to a full standing position from a chair as many times as possible in 30 seconds whilst keeping their arms crossed against their chest (Millor 2013). Measurement units = repetitions in 30 seconds
Time frame: change from baseline to 24 weeks
handgrip strength
Upper body muscle function was measured by isometric handgrip strength and sit-to-stand performance, respectively. When performing the handgrip strength assessments, participants were seated, instructed to keep their elbow at 90° and asked to squeeze a handgrip dynamometer (Sammons Preston Roylan, Bolingbrook, IL) to their maximum ability for a period of up to five seconds (Mathiowetz 2002). Three trials were performed with the subject's dominant hand with one-minute rest between trials and the best result used for analysis (Roberts 2011). Measurement units = kilograms

Quality of Life (EQ-5D-EL)
The EQ-5D-EL descriptive system comprises the following five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has three levels: no problems, some problems and extreme problems.

Sarcopenia status (SARC-F)
The SARC-F questionnaire is a rapid diagnostic test used to screen individuals for sarcopenia. There are five SARC components: strength, assistance with walking, rising from a chair, climbing stairs, and falls. The scores range from 0 to 2 points for each of the five components, allowing a total score of 0-10. Studies have suggested that a score equal to or greater than four is predictive of sarcopenia and poor health outcomes.
