    Abstract

    Background: Arm crank ergometry (ACE) has been shown to elicit marked improvements in lower body exercise capacity among older individuals. It is currently unknown whether ACE is effective in alleviating functional consequences of aging, such as balance and physical function. Objective: To determine the efficacy of ACE training on balance, mobility and cardiorespiratory fitness in older people. Design and Participants: Two-arm, randomised parallel trial; assessment at baseline and post-intervention. Participants who were aged >65 years and community-dwelling. Exclusion criteria included neurological and musculoskeletal disease, cognitive problems and/or cardiovascular/pulmonary diseases. Interventions: Participants were randomly assigned to six weeks of seated ACE (n = 10) or stationary cycling (control group) (n = 10) training, 3 times per week. Main outcome measures: The outcomes were functional balance and mobility, postural sway, upper body strength and cardiorespiratory fitness. Results: ACE training resulted in increased functional reach distance (d= 0.83 – 1.28), faster timed-up-and-go execution (d= 1.36) and reduced mediolateral postural sway (d= 0.8 - 1.3). Both ACE and CYC interventions elicited similar increases in mode-specific (%∆ ~25) and cross-transfer (%∆ ~13) peak oxygen uptake (P<0.05). Conclusions: The findings highlight that ACE training is effective in alleviating functional consequences of ageing, such as balance and mobility.
