Purpose: The aim of this investigation was to compare the changes in endurance running performance and physiological variables after a four-week period of high intensity interval training (HIIT) in either running or cycling in female athletes. Methods: Fourteen recreational female runners (age = 42  10 yr, height = 1.67  0.06 m, body mass = 61.6...
Article
Objective To identify interventions using wearable accelerometers to measure physical activity and/or sedentary behaviour in adults during hospitalization for an acute medical/surgical condition. Data sources Four databases were searched in August 2019 (MEDLINE, CINAHL, Scopus, EMBASE). Review methods Studies were selected if they described an in...

Purpose: The aim of this study was to investigate changes in physiological and performance variables in triathletes following a four week period of reduced training volume and increased training intensity. Methods: Sixteen moderately trained triathletes were randomly allocated to two groups: a control (CON) group which followed their usual train...

Objectives There are no agreed comprehensive tests for age-related changes to physical, emotional, mental and social functioning. Research into declining function focuses on those 75 years and older and little is known about age-related changes in younger people. The aims of this project were (1) to ascertain a comprehensive test battery that could...

The Exercise Science Toolkit is a web-based educational software program for exercise and health science tertiary students and professionals. The software was developed to facilitate student engagement with essential knowledge, skills and protocols in these disciplines, provide opportunities to conduct analyses on empirical data or simulations on a...

Objectives To investigate the levels of agreement between self-reported responses to the Adult Pre-exercise Screening System (APSS) questionnaire using online versus face-to-face (F2F) modalities. Design Convenience sample of adults completing a pre-exercise screening questionnaire using different modalities. Methods Adult volunteers (n = 94) wer...
Article
Objective: Older adults' health has been linked with time in moderate-to-vigorous physical activity (MVPA), and recent studies suggest time in sedentary behaviour may also be important. Time-use behaviours (MVPA, light physical activity, sedentary time and sleep) are co-dependent, and therefore their associations with health should be examined in...

Background Declining physical activity (PA) and associated health risk factors are well established. Workplace strategies to increase PA may be beneficial to ameliorate extensive sedentary behavior. This study assessed the effectiveness of two PA interventions in workplace settings. Methods Interventions were conducted over 40 days targeting insuf...

Introduction: The aim of this study was to investigate the effect of a 4 week high-intensity interval training (HIT) program on running and cycling performance. HIT is a training method which can be used to improve physical fitness in less time, and reduced training volume, than traditional endurance training. HIT allows athletes to accumulate time...
Article
End-stage renal disease (ESRD) is becoming more prevalent in Australia. As a result, strategies to improve quality of life when living with ESRD are becoming increasingly important. The Flinders Program has been developed to help support and increase the self-management capacity of people living with chronic disease. The Partners in Health (PIH) sc...

Stretching, either prior to exercise or at the end, or both, is typically carried out by all individuals undertaking sporting activity whether they be elite or recreational athletes. The many forms of stretching available to the athlete, either passive or active, have long been thought to improve performance, decrease injury and generally be advant...

Objective . Response time (RT) is important for health and human performance and provides insight into cognitive processes. It deteriorates with age, is associated with chronic physical activity (PA), and improves with PA interventions. We investigated associations between the amount and type of PA undertaken and the rate of change in RT for low-ac...
Article
Full-text available
Background. Low physical activity (PA) levels are associated with poor health risk factor profiles. Intervention strategies to increase PA and quantify the rate and magnitude of change in risk factors are important. Methods. Interventions were conducted over 40 days to increase PA in 736 insufficiently active (<150 min/wk PA) participants using ei...

Numerous studies have measured changes in fasting blood glucose (FBG) levels in response to physical activity (PA) interventions. While studies involving clinical populations such as type 2 diabetics typically report significant reductions, most others report no change in FBG. This study investigated changes in FBG in apparently healthy adults foll...

Increases in chronic illness due to sedentary lifestyles and poor metabolic fitness have led to numerous intervention strategies to promote physical activity (PA). This paper describes the methodological strategies of two short-term PA interventions. Outcome measures reported are PA adherence and compliance rates during the intervention and at 3, 6...

Article
Full-text available
The terminology used for monitoring and promoting physical activity and exercise among health and fitness professionals varies considerably. There is a large array of descriptor terms reported in the literature and used in day-to-day practice and this inconsistency can be confusing for clients and practitioners alike. The variation in terminology a...

To assess the applicability of risk-adjusted sequential control charts using the Paediatric Index of Mortality version 2 for monitoring of the quality of paediatric intensive care. Observational study. A registry of patient admissions to paediatric intensive care units (PICUs) in Australia and New Zealand. A total of 10,710 patients admitted to eig...

Sudden cardiac arrest (SCA) occurs in many thousands of Australians each year. Scientific evidence shows an increased survival rate for individuals who receive electrical defibrillation in the first few minutes after SCA. In the last decade automated (rhythm-detecting) external defibrillators (AEDs) have become available that are portable and affor...

It is not clear whether the global increase in weight problems in children is the result of excessive energy intake or decreasing energy expenditure. Methodological limitations have made it difficult to analyse. There is evidence that at least part of the problem may lie with increasing energy consumption, but it is important to examine the other s...
Article
This study investigated the influence of an exercise stimulus on pulmonary ventilation (V E) during severe levels of exercise in a group of ten athletes. The altered ventilation was assessed in relation to its effect on blood gas status, in particular to the incidence and severity of exercise induced hypoxaemia. Direct measurements of arterial bloo...
Article
Pulse oximetry is used extensively during exercise stress-testing in the clinical and sports medicine settings. There are few validation studies to assess the appropriateness of using pulse oximetry under conditions of potentially compromised peripheral blood flow. To study the accuracy of pulse oximetry during severe exercise stress, 10 athletes u...
