Ace And Ucp2 Gene Polymorphisms And Their Association With Baseline And Exercise-Related Changes In The Functional Performance Of Older Adults, Justin W. Keogh, Barry Palmer, Denise Taylor, Andrew Kilding

Justin Keogh

Maintaining high levels of physical function is an important aspect of successful ageing. While muscle mass and strength contribute to functional performance in older adults, little is known about the possible genetic basis for the heterogeneity of physical function in older adults and in how older adults respond to exercise. Two genes that have possible roles in determining levels of muscle mass, strength and function in young and older adults are angiotensin-converting enzyme (ACE) and mitochondrial uncoupling protein 2 (UCP2). This study examined whether polymorphisms in these two individual genes were associated with baseline functional performance levels and/or the training-related …

Objective: Cancer can affect an individual’s level of physical function and health related quality of life (HRQoL). Those requiring hospital admission may be at risk of further decline during hospitalisation. The aim of this study was to investigate physical functioning and HRQoL of cancer patients on admission and over the course of their hospital admission. Methods: A prospective observational study was undertaken on the inpatient wards of a specialist oncology hospital. Assessment measures were taken bi-weekly until discharge from hospital or if they became too unwell to continue. Functional outcome measures included timed-up and go test (TUG), 30 second sit …

To determine the feasibility of using the activPAL3TM activity monitor, and, to describe the activity patterns of residential aged care residents. Design: Cross-sectional. Setting: Randomly selected aged care facilities within 100 km of the Gold Coast, Queensland, Australia. Participants: Ambulatory, older (.60 years) residential aged care adults without cognitive impairment. Measurements: Feasibility was assessed by consent rate, sleep/wear diary completion, and through interviews with staff/participants. Activity patterns (sitting/lying, standing, and stepping) were measured via activPAL3TM monitors worn continuously for seven days. Times spent in each activity were described and then compared across days of the week and hours of the …

Objective Benefits, Participant Perceptions And Retention Rates Of A New Zealand Community-Based, Older-Adult Exercise Programme, Justin Keogh, John Rice, Denise Taylor, Andrew Kilding

Justin Keogh

INTRODUCTION: Most exercise studies for older adults have been university- or hospital-based. Little is known about the benefits and factors influencing long-term participation in community-based exercise programmes, especially in New Zealand. AIM: To quantify the objective benefits, participant perceptions and retention rates of a New Zealand community-based exercise programme for adults (60 years or older). METHODS: Study 1 involved assessing the benefits of 12 weeks’ training on a convenience sample of 62 older adults commencing the never2old Active Ageing programme. Study 2 assessed the perceptions of 150 current participants on a variety of programme components that could act as barriers …


Perceived Barriers, Benefits And Motives For Physical Activity: Two Primary-Care Physical Activity Prescription Programs, Asmita Patel, Grant M. Schofield, Gregory S. Kolt, Justin Keogh Jun 2013

Perceived Barriers, Benefits And Motives For Physical Activity: Two Primary-Care Physical Activity Prescription Programs, Asmita Patel, Grant M. Schofield, Gregory S. Kolt, Justin Keogh

Justin Keogh

This study examined whether perceived barriers, benefits, and motives for physical activity differed based on allocation to 2 different types of primary-care activity prescription programs (pedometer-based vs. time-based Green Prescription). Eighty participants from the Healthy Steps study completed a questionnaire that assessed their perceived barriers, benefits, and motives for physical activity. Factor analysis was carried out to identify common themes of barriers, benefits, and motives for physical activity. Factor scores were then used to explore betweengroups differences for perceived barriers, benefits, and motives based on group allocation and demographic variables. No significant differences were found in factor scores based on …


Quantitative Assessment Of Quality Of Life In New Zealand Prostate Cancer Survivors: The Effect Of Androgen Deprivation Therapy, Justin Keogh, C U. Krägeloh, D Shepherd, C Ryan, S Osborne, J Masters, R D. Macleod Jun 2013

Quantitative Assessment Of Quality Of Life In New Zealand Prostate Cancer Survivors: The Effect Of Androgen Deprivation Therapy, Justin Keogh, C U. Krägeloh, D Shepherd, C Ryan, S Osborne, J Masters, R D. Macleod

Men with prostate cancer experience many challenges to their quality of life (QOL). While some of these challenges reflect the direct effects of the cancer, additional side-effects and symptoms are also associated with common treatments especially androgen deprivation therapy (ADT). While several studies have examined the effects of ADT on the QOL of men with prostate cancer, much of this research is between 10-20 years old and was conducted in North America or Europe. This study therefore examined the effects of ADT on QOL in prostate cancer patients (survivors) in the Southern hemisphere. The registries of two New Zealand based …


Body Composition, Physical Fitness, Functional Performance, Quality Of Life, And Fatigue Benefits Of Exercise For Prostate Cancer Patients: A Systematic Review, Justin W. L. Keogh, Roderick D. Macleod Sep 2012

Body Composition, Physical Fitness, Functional Performance, Quality Of Life, And Fatigue Benefits Of Exercise For Prostate Cancer Patients: A Systematic Review, Justin W. L. Keogh, Roderick D. Macleod

Justin Keogh

Context: Prostate cancer patients, especially those on androgen deprivation therapy (ADT), experience many symptoms that make it difficult to maintain their independence and quality of life. Because ADT acts by means of reducing testosterone production, exercise may offset many of the ADT side effects and those of the cancer itself.Objectives: This systematic review of the literature evaluates whether exercise could reduce symptoms and improve quality of life for prostate cancer patients.Methods: Using relevant databases and key words, 12 training studies were found meeting the inclusion and exclusion criteria.Results: Grade A level evidence was observed for the benefits of exercise in …


Evidence For Biomechanics And Motor Learning Research Improving Golf Performance, Justin W. L. Keogh, Patricia A. Hume Sep 2012

Evidence For Biomechanics And Motor Learning Research Improving Golf Performance, Justin W. L. Keogh, Patricia A. Hume

Justin Keogh

The aim of this review was to determine how the findings of biomechanics and motor control/learning research may be used to improve golf performance. To be eligible, the biomechanics and motor learning studies had to use direct (ball displacement and shot accuracy) or indirect (clubhead velocity and clubface angle) golf performance outcome measures. Biomechanical studies suggested that reducing the radius path of the hands during the downswing, increasing wrist torque and/or range of motion, delaying wrist motion to late in the downswing, increasing downswing amplitude, improving sequential acceleration of body parts, improving weight transfer, and utilising X-factor stretch and physical …

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 …
