Objective And Subjective Benefits Of A Community-Based, Older Adult Multi-Component Exercise Programme, Justin Keogh, John Rice, Denise Taylor, Andrew Kilding

Justin Keogh

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 or …

Practical Applications Of Biomechanical Principles In Resistance Training: Neuromuscular Factors And Relationships, Jason Lake, Paul A. Swinton, Justin Keogh

Justin Keogh

This paper is the second in our three part series examining how a variety of biomechanical principles and concepts have direct relevance to the prescription of resistance training for the general and athletic populations as well as for musculoskeletal injury rehabilitation. In this paper, we considered different neuromuscular characteristics of resistance exercise. We started by defining the causes of motion, discussing force and Newton’s second law of linear motion. This led to discussion of impulse, and how its relationship with momentum can be used to study force-time curves recorded from different ground-based resistance exercises. This enables the sports biomechanist to …

Perception And Responses To Different Forms Of Aqua-Based Exercise Among Older Adults With Osteoarthritis, Alison Fisken, Deborah L. Waters, Wayne Hing, Michael Steele, Justin Keogh

Wayne Hing

Osteoarthritis (OA) is prevalent among older adults. Aqua-based exercise is often recommended as a therapeutic intervention. Limited evidence exists on the effectiveness of this form of exercise intervention. Perceptions of pain, mean, and maximum heart rate (HR) responses, ratings of perceived exertion (RPE), and subjective enjoyment to different forms of aqua-based exercise were investigated. Thirteen older adults with documented OA completed five aquatic exercise sessions: body-weight aqua-fitness (AF), body-weight aqua-jogging (AJ), resisted aqua-fitness (RAF), resisted aqua-jogging (RAJ), and hydrotherapy (HYD). HYD was rated most enjoyable with AF deemed as an acceptable alternative. Pain scores immediately postexercise were significantly lower than …

Mechanomyography; Lasers For Non-Invasive Quantification Of Muscle Recovery From Exercise Induced Fatigue, Nicholas Rosser, Darryl Mcandrew, Donald Iverson

Darryl J McAndrew

Muscle fatigue is a common clinical sign and possible precursor to musculoskeletal injury. Existing methods of detecting muscle fatigue qualify changes within muscle or across joints, but are expensive, invasive or difficult to use. A technique of mechanomyography utilising maximal percutaneous stimulation (known as the Muscle Displacement Laser {MDL}) is an easy non-invasive assessment tool, which may have considerable application in measuring muscle fatigue and determining recovery. Specifically, this study attempted to validate the MDL as a tool to measure muscle fatigue and determine the time-course of recovery from Delayed Onset of Muscle Soreness in human biceps brachii muscle. Methods: …

Research Review: Exercise Can Be So Demanding, Michael Climstein, Joe Walsh

Mike Climstein

Introduction: It’s the last week of university and I’m preparing my last lecture for a colleague who is in Las Vegas at a strength and conditioning conference. Hmmph! Just not fair – and on top of sending an email from the poolside reminding me to give the lecture, he has the audacity to complain about the 40°C weather (did I mention it’s been single digits temperature here on the Gold Coast in the mornings?) Anyway, getting back on topic, I’m preparing his lecture on obesity and am including a number of slides on basal metabolic rate, resting metabolic rate, assessment …

Physical And Psychosocial Function In Residential Aged-Care Elders: Effect Of Nintendo Wii Sports Games, J. W. L. Keogh, N. Power, L. Wooller, P. Lucas, C. Whatman

Justin Keogh

This mixed-methods, quasi-experimental pilot study examined whether the Nintendo Wii Sports (NWS) active video game (exergame) system could significantly improve the functional ability, physical activity levels, and quality of life of 34 older adults (4 men and 30 women, 83 ± 8 yr) living in 2 residential aged-care (RAC) centers. Change score analyses indicated the intervention group had significantly greater increases in bicep curl muscular endurance, physical activity levels, and psychological quality of life than the control group (p

Can Exercise Ameliorate Treatment Toxicity During The Initial Phase Of Testosterone Deprivation In Prostate Cancer Patients? Is This More Effective Than Delayed Rehabilitation?, Robert Newton, Dennis Taaffe, Nigel Spry, Prue Cormie, Suzanne Chambers, Robert Gardiner, David Shum, David Joseph, Daniel Galvao

Prue Cormie

Background: There has been substantial increase in use of androgen deprivation therapy as adjuvant management of prostate cancer. However, this leads to a range of musculoskeletal toxicities including reduced bone mass and increased skeletal fractures compounded with rapid metabolic alterations, including increased body fat, reduced lean mass, insulin resistance and negative lipoprotein profile, increased incidence of cardiovascular and metabolic morbidity, greater distress and reduced quality of life. Numerous research studies have demonstrated certain exercise prescriptions to be effective at preventing or even reversing these treatment toxicities. However, all interventions to date have been of rehabilitative intent being implemented after a …

Effect Of The Planet Health Intervention On Eating Disorder Symptoms In Massachusetts Middle Schools, 2005-2008, S. Bryn Austin, Jennifer L. Spadano-Gasbarro, Mary L. Greaney, Emily A. Blood, Anne T. Hunt, Tracy K. Richmond, Monica L. Wang, Solomon Mezgebu, Stavroula K. Osganian, Karen E. Peterson

INTRODUCTION: The Planet Health obesity prevention curriculum has prevented purging and abuse of diet pills (disordered weight control behavior [DWCB]) in middle-school girls in randomized trials, but the effects of Planet Health on DWCB when implemented by schools under dissemination conditions are not known. METHODS: Massachusetts Department of Public Health and Blue Cross Blue Shield of Massachusetts disseminated Planet Health as part of the 3-year, Healthy Choices obesity prevention program in middle schools. We conducted an evaluation in 45 schools from fall 2005 to spring 2008. We gathered data from school staff to quantify intervention activities, and we gathered anonymous …

Acute Interval Exercise Intensity Does Not Affect Appetite And Nutrient Preferences In Overweight And Obese Males, Shaea Alkahtani, Nuala Byrne, Andrew Hills, Neil King

Nuala Byrne

This study investigated the influence of two different intensities of acute interval exercise on food preferences and appetite sensations in overweight and obese men. Twelve overweight/obese males (age=29.0±4.1 years; BMI =29.1±2.4 kg/m2) completed three exercise sessions: an initial graded exercise test, and two interval cycling sessions: moderate-(MIIT) and high-intensity (HIIT) interval exercise sessions on separate days in a counterbalanced order. The MIIT session involved cycling for 5-minute repetitions of alternate workloads 20% below and 20% above maximal fat oxidation. The HIIT session consisted of cycling for alternate bouts of 15 seconds at 85% VO2max and 15 seconds unloaded recovery. Appetite …

Interval Training Intensity Affects Energy Intake Compensation In Obese Men, Shaea Alkahtani, Nuala Byrne, Andrew Hills

Nuala Byrne

Purpose: Compensatory responses may attenuate the effectiveness of exercise training in weight management. The aim of this study was to compare the effect of moderate- and high-intensity interval training on eating behavior compensation. Methods: Using a crossover design, 10 overweight and obese men participated in 4-week moderate (MIIT) and high (HIIT) intensity interval training. MIIT consisted of 5-min cycling stages at ±20% of mechanical work at 45%VO2peak, and HIIT consisted of alternate 30-s work at 90%VO2peak and 30-s rests, for 30 to 45 min. Assessments included a constant-load exercise test at 45%VO2peak for 45 min followed by 60-min recovery. Appetite …
