The Current State Of Subjective Training Load Monitoring—A Practical Perspective And Call To Action, Joseph O. C. Coyne, G. Gregory Haff, Aaron J Coutts, Robert U. Newton, Sophia Nimphius

Research outputs 2014 to 2021

This commentary delivers a practical perspective on the current state of subjective training load (TL) monitoring, and in particular sessional ratings of perceived exertion, for performance enhancement and injury prevention. Subjective measures may be able to reflect mental fatigue, effort, stress, and motivation. These factors appear to be important moderators of the relationship TL has with performance and injury, and they also seem to differ between open and closed skill sports. As such, mental factors may affect the interaction between TL, performance, and injury in different sports. Further, modeling these interactions may be limited due to the assumption that an …

Feasibility And Preliminary Efficacy Of A 10-Week Resistance And Aerobic Exercise Intervention During Neoadjuvant Chemoradiation Treatment In Rectal Cancer Patients, Favil Singh, Daniel A. Galvão, Robert Newton, Nigel A. Spry, Michael K. Baker, Dennis Taaffe

Research outputs 2014 to 2021

Background:

Neoadjuvant chemoradiation treatment (CRT) in rectal cancer patients is associated with a reduction in physical capacity, lean mass and increased fatigue. As a countermeasure to these treatment-related adverse effects, we examined the feasibility and preliminary efficacy of a 10-week exercise program during CRT.

Methods:

Ten rectal cancer patients (7 men, aged 27-70 years, body mass index = 26.4 ± 3.8 kg/m2) receiving CRT undertook supervised resistance and aerobic exercise twice weekly. Assessments were undertaken pre- and post-intervention for upper and lower body muscle strength by 1-RM, muscle endurance, physical performance tests, body composition by dual X-ray absorptiometry, quality of …

“…Like You’Re Pushing The Snowball Back Up Hill”—The Experiences Of Australian Physiotherapists Promoting Non-Treatment Physical Activity: A Qualitative Study, Breanne E. Kunstler, Paul D. O'Halloran, Jill L. Cook, Joanne L. Kemp, Caroline Finch

Research outputs 2014 to 2021

Participating in physical activity is important for maintaining general health. When physiotherapists promote physical activity for the purposes of maintaining or improving a patient‟s general health, they are promoting non-treatment physical activity. Physiotherapists have a responsibility to promote non-treatment physical activity to their patients while also providing the patient with treatment for their presenting complaint. This qualitative study explored the experiences of Australian physiotherapists promoting non-treatment physical activity to patients with musculoskeletal conditions. Ten Australian physiotherapists treating patients with musculoskeletal conditions in private practice and outpatient settings were recruited using a social media campaign and snowballing. All interviewees received one …

Research outputs 2014 to 2021

Objective Health clubs (HC) and personal trainers (PT) are traditional outlets for the promotion of physical activity (PA) and exercise programming. As physicians are increasingly being called on to write exercise prescriptions for their patients, this study sought to investigate the level of integration between the healthcare and fitness systems.

Design An internet study was designed with five domains to understand physicians’: (1) overall perception of HC, (2) appropriateness and recommendation of HC and PT to their patients, (3) attitude regarding specific aspects of HC, (4) support of patient participation in HC sponsored exercise and (5) elements of HC that …

Intrarater Reliability And Agreement Of The Physioflow Bioimpedance Cardiography Device During Rest, Moderate And High-Intensity Exercise, Nicole Gordon, Chris R. Abbiss, Andrew J. Maiorana, Kieran J. Marston, Jeremiah J. Peiffer

Research outputs 2014 to 2021

The PhysioFlow bioimpedance cardiography device provides key measures of central systolic and diastolic and peripheral vascular function. Many of these variables have not been assessed for intrarater reliability and agreement during rest, submaximal exercise and high-intensity interval exercise. Twenty healthy adults (age: 26±4 years) completed two identical trials beginning with five minutes of rest followed by two 5-minute submaximal cycling bouts at 50% and 70% of peak power output. Subjects then completed ten 30-second cycling intervals at 90% of peak power output interspersed with 60 s of passive recovery. Bioimpedance cardiography (PhysioFlow; Manatec Biomedical, France) monitored heart rate, stroke volume, …

Time On Androgen Deprivation Therapy And Adaptations To Exercise: Secondary Analysis From A 12-Month Randomized Controlled Trial In Men With Prostate Cancer, Dennis R. Taaffe, Laurien M. Buffart, Robert U. Newton, Nigel Spry, James Denham, David Joseph, David Lamb, Suzanne K. Chambers, Daniel A. Galvao

Research outputs 2014 to 2021

Objectives

To explore if duration of previous exposure to androgen deprivation therapy (ADT) in men with prostate cancer (PCa) undertaking a year-long exercise programme moderates the exercise response with regard to body composition and muscle performance, and also to explore the moderator effects of baseline testosterone, time since ADT, and baseline value of the outcome.

Patients and Methods

In a multicentre randomized controlled trial, 100 men who had previously undergone either 6 months (short-term) or 18 months (long-term) of ADT in combination with radiotherapy, as part of the TROG 03.04 RADAR trial, were randomized to 6 months supervised exercise, followed …

An Overview Of Technical Considerations When Using Quantitative Real-Time Pcr Analysis Of Gene Expression In Human Exercise Research, Jujiao Kuang, Xu Yan, Amanda Genders, Cesare Granata, David J. Bishop

Research outputs 2014 to 2021

Gene expression analysis by quantitative PCR in skeletal muscle is routine in exercise studies. The reproducibility and reliability of the data fundamentally depend on how the experiments are performed and interpreted. Despite the popularity of the assay, there is a considerable variation in experimental protocols and data analyses from different laboratories, and there is a lack of consistency of proper quality control steps throughout the assay. In this study, we present a number of experiments on various steps of quantitative PCR workflow, and demonstrate how to perform a quantitative PCR experiment with human skeletal muscle samples in an exercise study. …

The Effects Of Acute And Chronic Sprint-Interval Training On Cytokine Responses Are Independent Of Prior Caffeine Intake, Guilherme Ferreira, Leandro Felippe, Rômulo Bertuzzi, David Bishop, Emiliano Barreto, Fernando De-Oliveira, Adriano Lima-Silva

Research outputs 2014 to 2021

We examined the effect of acute and chronic sprint interval training (SIT), with or without prior caffeine intake, on levels of exercise-induced inflammatory plasma cytokines [interleukin (IL)-6, IL-10, tumor necrosis factor (TNF)-α]. Twenty physically-active men ingested either a placebo (n = 10) or caffeine (n = 10) 1 h before each SIT session(13-s × 30-s sprint/15 s of rest) during six training sessions (2 weeks). The early (before, immediately after, and 45 min after the exercise) and late (24 and 48 h after the exercise) cytokine and creatine kinase (CK) responses were analyzed for the first and last …

Effects Of Long-Term Participation In Tennis On Cognitive Function In Elderly Individuals, Scott Culpin

Theses: Doctorates and Masters

Many studies have reported the relationship between exercise and cognition with conflicting results. This may be due to differences in intervention durations, session lengths, intensities, and type of exercise. It has been suggested that exercises requiring greater cognitive demand such as football, basketball and racquet sports, are protective against cognitive decline, compared to less cognitively demanding exercises such as swimming, cycling and running, however, research concerning exercise types are currently limited. The present study tested the hypothesis that elderly individuals who had been regularly playing tennis more than 10 years, would have greater cognitive function than those who had been …

Interpreting Signal Amplitudes In Surface Electromyography Studies In Sport And Rehabilitation Sciences, Andrew D. Vigotsky, Israel Halperin, Gregory J. Lehman, Gabriel S. Trajano, Taian M. Vieira

Research outputs 2014 to 2021

Surface electromyography (sEMG) is a popular research tool in sport and rehabilitation sciences. Common study designs include the comparison of sEMG amplitudes collected from different muscles as participants perform various exercises and techniques under different loads. Based on such comparisons, researchers attempt to draw conclusions concerning the neuro- and electrophysiological underpinning of force production and hypothesize about possible longitudinal adaptations, such as strength and hypertrophy. However, such conclusions are frequently unsubstantiated and unwarranted. Hence, the goal of this review is to discuss what can and cannot be inferred from comparative research designs as it pertains to both the acute and …
