Perceived Benefits, Motives, And Barriers To Aqua-Based Exercise Among Older Adults With And Without Osteoarthritis, Alison Fisken, Justin Keogh, Deborah L. Waters, Wayne Hing Jul 2013

Perceived Benefits, Motives, And Barriers To Aqua-Based Exercise Among Older Adults With And Without Osteoarthritis, Alison Fisken, Justin Keogh, Deborah L. Waters, Wayne Hing

Justin Keogh

This study aimed to (a) identify factors that motivate older adults to participate in aqua-based exercise; (b) identify potential barriers; and (c) compare perceptions between older adults with and without osteoarthritis (OA). Fifteen adults above 60 years of age participated in one of three focus groups during which they discussed perceived benefits, motives, and barriers to aqua exercise. Pain reduction was considered a major benefit among those with OA, improved health and fitness was a principal benefit for those without OA. All participants felt that the instructor could act as both a motivator and barrier; the most significant barrier was …


Development Of A Clinical Multiple-Lunge Test To Predict Falls In Older Adults, Ruth Wagenaar, Justin W. Keogh, Denise Taylor Aug 2012

Development Of A Clinical Multiple-Lunge Test To Predict Falls In Older Adults, Ruth Wagenaar, Justin W. Keogh, Denise Taylor

Justin Keogh

Objective: To develop a new Multiple-Lunge Test to distinguish between fallers and nonfallers in community-dwelling older adults.Design: A cross-sectional design was used to establish the sensitivity and specificity of the test to predict faller status based on retrospective self-reported fall history. Setting: Local retirement villages.Participants: Community-dwelling older adults (N 130; mean age SD, 77 7y) with (n 40) and without (n 90) a history of falls.Interventions: The Multiple-Lunge Test required individuals to lunge forward to a step length determined as 60% of their leg length, and return to start, for 5 consecutive repetitions. Interday and intraday test-retest reliability of the …


Strength And Coordination Training Are Both Effective In Reducing The Postural Tremor Amplitude Of Older Adults, Justin W.L. Keogh, Steve Morrison, Rod Barrett Dec 2009

Strength And Coordination Training Are Both Effective In Reducing The Postural Tremor Amplitude Of Older Adults, Justin W.L. Keogh, Steve Morrison, Rod Barrett

Justin Keogh

The current study investigated the effect of 2 different types of unilateral resistance training on the postural tremor output of 19 neurologically healthy men age 70–80 yr. The strength- (n = 7) and coordination-training (n = 7) groups trained twice a week for 6 wk, performing dumbbell biceps curls, wrist flexions, and wrist extensions, while the control group (n = 5) maintained their normal activities. Changes in index-finger tremor (RMS amplitude, peak, and proportional power) and upper limb muscle coactivation were assessed during 4 postural conditions that were performed separately with the trained and untrained limbs. The 2 training groups …


Digit Force Control In Older Adults: Benefits Of Resistance-Training?, Justin W.L. Keogh May 2006

Digit Force Control In Older Adults: Benefits Of Resistance-Training?, Justin W.L. Keogh

Justin Keogh

This paper seeks to review the effect on digit force control of: 1) the ageing process; and 2) the resistance-training in older adults. Significant age-related decreases in finger-pinch force control were observed in many but not all studies. Those that didn't report age-related differences involved bi-digit finger-pinch tasks requiring the production of constant forces only. This suggests that the age-related decline in force control becomes more pronounced the more challenging the force production task. While three studies reported that resistance-training improved older adults' digit force control capabilities, it is unclear if these improvements would occur in tasks that: 1) require …
