- Description: This study aims to present a new approach towards the analysis of intervention time-series studies in the context of sports-related injury data. We used Victoria-wide hospital admission injury data associated with the sport of Australian football during the period 2006 to 2013. To estimate the state-wide effect of an implemented exercise training intervention that aimed to reduce the number of football-related injuries, time-series analysis was performed using a generalised least square (GLS) method. We show how the GLS method can be used to evaluate the impact of the intervention. Trend and seasonal patterns time series were also assessed using the 'Seasonal and Trend decomposition using Loess' nonparametric seasonal decomposition procedure. The model identified a decreasing trend in the seasonally adjusted number of injuries after the implementation of the intervention in the hospital admission data. The seasonal decomposition plots also indicate strong seasonal patterns in the injury time series.

- Description: The number of people affected by dementia across the world is estimated to grow over the coming decades. It is a condition that leads to global and nonreversible cognitive impairment. As well as creating dependency in everyday activities, dementia increases the risk of older people experiencing a fall. Falls are globally recognized as a public health problem, given their high prevalence and severe consequences among older people. Several interventions have been developed to prevent falls, with robust evidence to support exercise-based interventions and in particular Tai Chi. Tai Chi exercise is a mind-body exercise that has evidence to support its potential to improve physical, cognitive, and mental health more generally as well as prevent falls. Most exercise trials to date have excluded people with dementia, and so there is little evidence to guide the use of Tai Chi for this patient group. Further, the methodological quality and heterogeneity of approaches used in Tai Chi studies such as the exercise dose, outcomes measured, and how adherence was reported, makes it difficult to make firm conclusions. Emergent evidence suggests Tai Chi is an enjoyable and safe form of exercise for community-dwelling older people with mild to moderate dementia and their informal carers. It has strong potential to improve quality of life and prevent falls among this patient group. The mechanism for its effectiveness is not clear but it is potentially via a positive impact on both cognitive and physical functioning. Clinical practice recommendations for exercise prescribers are provided with an emphasis on how to attract and sustain high levels of adherence. © 2022 Elsevier Inc. All rights reserved.

- Description: Exercise is effective in preventing falls among older adults. However, few studies have included people living with dementia and their carers and explored their experiences. The aim of this study is to explore what affects the acceptability of exercise interventions to better meet the needs of people with dementia and their carers as a dyad. Observations, field notes containing participant's and instructor's feedback, and focus groups with 10 dyads involved in Tai Chi classes for 3 or 4 weeks in two sites in the South of England were thematically analyzed to understand their experiences. Findings suggest that dyads' determination to achieve the benefits of Tai Chi facilitated their adherence, whereas a member of the dyad's low sense of efficacy performing the movements during classes was a barrier. Simplifying class content and enhancing the clarity of instructions for home-based practice will be key to support the design of future exercise interventions. © 2019 The Authors.

- Description: Objectives: The aim of this study was to understand what influenced people living with dementia and their family carers’ adherence to the home-based component of a Tai Chi exercise intervention. Method: Dyads, of people living with dementia and their family carers, who participated in the intervention arm of the Tai Chi for people living with dementia trial, were invited to join weekly Tai Chi classes for 20 weeks and practice at home. Semi-structured dyadic home interviews were conducted on average after 16 weeks of classes. The views of 15 dyads with a range of home practice adherence were sought in semi-structured interviews. The interviews were analysed using an inductive thematic approach. Results: Most participants found time to practise Tai Chi at home and practised for 18 hours on average. Amongst the barriers to adherence were participants’ competing commitments and a booklet not sufficiently conveying the Tai Chi movements. Hence, a video or DVD was requested by participants. Facilitators of their adherence to the home-based component of the intervention were their enjoyment of the practice and the development of a habit, which was supported by their commitment to the study and their willingness to benefit from Tai Chi. Conclusion: Enjoyment and perceived benefits had a great impact on participants living with dementia and their carers’ adherence to home-based Tai Chi practice. However, difficulties to perceive the Tai Chi movements through images might be hindering sustained participation. Hence, alternative aids such as videos and DVDs should be explored to facilitate adherence. © The Author(s) 2020.

- Description: Purpose: The interaction of ageing and exercise training status on left-ventricular (LV) peak strain is unclear. Additionally, strain analysis across the entire cardiac cycle facilitates a more detailed assessment of deformation, yet this has not been implemented to characterize the ageing LV and in association with training status. This study investigated healthy ageing and training status on LV systolic and diastolic strain utilizing novel echocardiographic applications. Methods: Forty healthy males were included and allocated into four groups; young recreationally active (YRA,n = 9; 28 ± 5 years), old recreationally active (ORA, n = 10; 68 ± 6), young trained (YT,n = 10; 27 ± 6 years), and old trained (OT, n = 11, 64 ± 4 years) groups. Two-dimensional speckle-tracking echocardiography was performed to ascertain peak LV longitudinal and circumferential strain (base and apex) strain within each myocardial layer and at 5% increments across the cardiac cycle. Results: Older groups had lower diastolic longitudinal lengthening and circumferential expansion between 40–85% mid-diastole, regardless of training status (P < 0.05). Whereas, strain throughout systole was similar between groups (P > 0.05). Longitudinal and circumferential (base and apex) peak and layer-specific strain did not differ between groups (P > 0.05). Conclusion: Novel applications of diastolic strain revealed lower age-associated LV longitudinal lengthening and circumferential expansion in older age. Yet, diastolic strain profiles did not differ based on chronic habits of exercise training and, thus, older trained men did not demonstrate an attenuation of age-associated differences in mid-diastolic LV strain. © 2020, The Author(s).

- Description: There is a wide variance in the magnitude of physiological adaptations after resistance or endurance training. The incidence of “non” or “poor” responders to training has been reported to represent as high as 40% of the project’s sample. However, the incidence of poor responders to training can be ameliorated with manipulation of either the training frequency, intensity, type and duration. Additionally, global non‐response to cardio‐respiratory fitness training is eliminated when evaluating several health measures beyond just the target variables as at least one or more measure improves. More research is required to determine if altering resistance training variables results in a more favourable response in individuals with an initial poor response to resistance training. Moreover, we recommend abandoning the term “poor” responders, as ultimately the magnitude of change in cardiorespiratory fitness in response to endurance training is similar in “poor” and “high” responders if the training frequency is subsequently increased. Therefore, we propose “stubborn” responders as a more appropriate term. Future research should focus on developing viable physiological and lifestyle screening tests that identify likely stubborn responders to conventional exercise training guidelines before the individual engages with training. Exerkines, DNA damage, metabolomic responses in blood, saliva and breath, gene sequence, gene expression and epigenetics are candidate biomarkers that warrant investigation into their relationship with traina-bility. Crucially, viable biomarker screening tests should show good construct validity to distinguish between different exercise loads, and possess excellent sensitivity and reliability. Furthermore “red flag” tests of likely poor responders to training should be practical to assess in clinical settings and be affordable and non‐invasive. Early identification of stubborn responders would enable op-timization of training programs from the onset of training to maintain exercise motivation and optimize the impact on training adaptations and health. © 2022 by the authors.

- Description: Aim: To explore the effects of exercise (water-based or land-based) and/or manual therapies on pain in adults with clinically and/or radiographically diagnosed hip osteoarthritis (OA). Methods: A systematic review and meta-analysis was performed, with patient reported pain assessed using a visual analogue scale (VAS) or the Western Ontario and McMaster Universities Arthritis Index (WOMAC) pain subscale. Data were grouped by follow-up time (0-3 months=short term; 4-12 months=medium term and; >12 months=long term), and standardised mean differences (SMD) with 95% CIs were used to establish intervention effect sizes. Study quality was assessed using modified PEDro scores. Results: 19 trials were included. Four studies showed short-term benefits favouring water-based exercise over minimal control using the WOMAC pain subscale (SMD -0.53, 95% CI -0.96 to -0.10). Six studies supported a short-term benefit of land-based exercise compared to minimal control on VAS assessed pain (SMD -0.49, 95% CI -0.70 to -0.29). There were no medium (SMD -0.23, 95% CI -0.48 to 0.03) or long (SMD -0.22, 95% CI -0.51 to 0.06) term benefits of exercise therapy, or benefit of combining exercise therapy with manual therapy (SMD -0.38, 95% CI -0.88 to 0.13) when compared to minimal control. Conclusions: Best available evidence indicates that exercise therapy (whether land-based or water-based) is more effective than minimal control in managing pain associated with hip OA in the short term. Larger highquality RCTs are needed to establish the effectiveness of exercise and manual therapies in the medium and long term.

In study one, 482 athletes completed the Type D personality questionnaire (DS14), stress thermometer and MCOPE in relation to a recently experienced sport stressor. Type D was associated with increased levels of perceived stress and selection of coping strategies (more emotion and avoidance coping) as well as perceptions of their effectiveness. In study two, 32 participants completed a rugby league circuit task and were assessed on pre-performance anxiety, post-performance affect and coping. Type D was associated with poorer performance (reduced distance more errors), decreases in pre-performance self-confidence and more use of maladaptive resignation/withdrawal coping. Findings suggest that Type D is associated with maladaptive coping and reduced performance.

- Description: There is an emerging body of literature relating to the effectiveness of frequent aerobic exercise as a prophylactic for age-associated dysfunction of large arteries, yet systematic evaluation and precise estimate of this effect is unknown. We conducted a systematic review and meta-analysis of controlled studies examining flow mediated dilatation (FMD) of athletic older persons and otherwise healthy sedentary counterparts to (i) compare FMD as a determinant of endothelial function between athletes and sedentary individuals and, (ii) summarize the effect of exercise training on FMD in studies of sedentary aging persons. Studies were identified from systematic search of major electronic databases from inception to January 2018. Study quality was assessed before conducting a random effects meta-analysis to calculate a pooled ES (mean difference) with 95% CI's. Thirteen studies [4 interventional (n = 125); 10 cross-sectional [including one study from the interventional analysis; (n = 485)] with age ranges from 62 to 75 years underwent quantitative pooling of data. The majority of study participants were male. Older athletes had more favorable FMD compared with sedentary controls (2.1%; CI: 1.4, 2.8%; P < 0.001). There was no significant improvement in the vascular function of sedentary cohorts following a period of exercise training (0.7%; CI: −0.675, 2.09%; P = 0.316). However, there was a significant increase in baseline diameter from pre to post intervention (0.1 mm; CI: 0.07, 0.13 mm; P < 0.001). In addition, there was no significant difference in endothelial independent vasodilation between the trained and sedentary older adults (1.57%; CI: −0.13, 3.27%; P = 0.07), or from pre to post exercise intervention (1.48%; CI: −1.34, 4.3%; P = 0.3). In conclusion, long-term aerobic exercise appears to attenuate the decline in endothelial vascular function, a benefit which is maintained during chronological aging. However, currently there is not enough evidence to suggest that exercise interventions improve vascular function in previously sedentary healthy older adults.

- Description: Adolescence is a critical time for developing lifelong healthy behaviors, including active lifestyles. Participation in sport and physical activity, however, declines during adolescence, and few studies have comprehensively identified why, particularly among rural girls. This article identifies a range of independent and interacting factors that influence sport and physical activity participation of rural adolescent girls. The socioecological model of health was used to guide four focus group discussions with Grade 7 girls (n = 34). The results showed that adolescent girls were positively influenced when sports or physical activities were fun, when they involved being with friends, and when they were supported by families and teachers through role modeling and positive feedback. A range of intrapersonal and organizational factors affected perceived self-competence, particularly the coeducational nature of school physical education classes and peer teasing, which supported social comparisons of skill level. In promoting sport and physical activity to rural adolescent girls, focus must be directed on developmentally appropriate activities that are fun, offering opportunities for single-sex classes, and generating cultural changes that encourage noncompetitive and self-referencing activities. © 2009 The Author(s).

- Description: Adolescence is a critical time for developing lifelong healthy behaviors, including active lifestyles. Participation in sport and physical activity, however, declines during adolescence, and few studies have comprehensively identified why, particularly among rural girls. This article identifies a range of independent and interacting factors that influence sport and physical activity participation of rural adolescent girls. The socioecological model of health was used to guide four focus group discussions with Grade 7 girls (n = 34). The results showed that adolescent girls were positively influenced when sports or physical activities were fun, when they involved being with friends, and when they were supported by families and teachers through role modeling and positive feedback. A range of intrapersonal and organizational factors affected perceived self-competence, particularly the coeducational nature of school physical education classes and peer teasing, which supported social comparisons of skill level. In promoting sport and physical activity to rural adolescent girls, focus must be directed on developmentally appropriate activities that are fun, offering opportunities for single-sex classes, and generating cultural changes that encourage noncompetitive and self-referencing activities. © 2009 The Author(s).

- Description: Hypertension, defined as persistently elevated systolic blood pressure (SBP) >140 mmHg and/or diastolic blood pressure (DBP) at least 90 mmHg (International Society of Hypertension guidelines), affects over 1.5 billion people worldwide. Hypertension is associated with increased risk of cardiovascular disease (CVD) events (e.g. coronary heart disease, heart failure and stroke) and death. An international panel of experts convened by the International Society of Hypertension College of Experts compiled lifestyle management recommendations as first-line strategy to prevent and control hypertension in adulthood. We also recommend that lifestyle changes be continued even when blood pressure-lowering medications are prescribed. Specific recommendations based on literature evidence are summarized with advice to start these measures early in life, including maintaining a healthy body weight, increased levels of different types of physical activity, healthy eating and drinking, avoidance and cessation of smoking and alcohol use, management of stress and sleep levels. We also discuss the relevance of specific approaches including consumption of sodium, potassium, sugar, fibre, coffee, tea, intermittent fasting as well as integrated strategies to implement these recommendations using, for example, behaviour change-related technologies and digital tools. **Please note that there are multiple authors for this article therefore only the name of the first 30 including Federation University Australia affiliates “Fadi Charchar, Priscilla Prestes, Britt Klein, Colette Browning, Olutope Akinnibosun and Shane Thomas” are provided in this record**

- Description: Telomeres are specialized nucleoprotein structures that protect chromosomal ends from degradation. These structures progressively shorten during cellular division and can signal replicative senescence below a critical length. Telomere length is predominantly maintained by the enzyme telomerase. Significant decreases in telomere length and telomerase activity are associated with a host of chronic diseases; conversely their maintenance underpins the optimal function of the adaptive immune system. Habitual physical activity is associated with longer leukocyte telomere length; however, the precise mechanisms are unclear. Potential hypotheses include regulation of telomeric gene transcription and/or microRNAs (miRNAs). We investigated the acute exercise-induced response of telomeric genes and miRNAs in twenty-two healthy males (mean age = 24.1±1.55 years). Participants undertook 30 minutes of treadmill running at 80% of peak oxygen uptake. Blood samples were taken before exercise, immediately post-exercise and 60 minutes post-exercise. Total RNA from white blood cells was submitted to miRNA arrays and telomere extension mRNA array. Results were individually validated in white blood cells and sorted T cell lymphocyte subsets using quantitative real-time PCR (qPCR). Telomerase reverse transcriptase (TERT) mRNA (P = 0.001) and sirtuin-6 (SIRT6) (P<0.05) mRNA expression were upregulated in white blood cells after exercise. Fifty-six miRNAs were also differentially regulated post-exercise (FDR <0.05). In silico analysis identified four miRNAs (miR-186, miR-181, miR-15a and miR-96) that potentially targeted telomeric gene mRNA. The four miRNAs exhibited significant upregulation 60 minutes post-exercise (P<0.001). Telomeric repeat binding factor 2, interacting protein (TERF2IP) was identified as a potential binding target for miR-186 and miR-96 and demonstrated concomitant downregulation (P<0.01) at the corresponding time point. Intense cardiorespiratory exercise was sufficient to differentially regulate key telomeric genes and miRNAs in white blood cells. These results may provide a mechanistic insight into telomere homeostasis and improved immune function and physical health. Funding NHMRC

- Description: Abstract Objectives Competitive endurance athletes commonly undertake periods of overload training in the weeks prior to major competitions. This investigation examined the effects of two seven-day high-intensity overload training regimes (HIT) on performance and physiological characteristics of competitive cyclists. Design The study was a matched groups, controlled trial. Methods Twenty-eight male cyclists (mean ± SD, Age: 33±10 years, Mass 74±7 kg, VO2 peak 4.7±0.5 L·min−1) were assigned to a control group or one of two training groups for seven consecutive days of HIT. Before and after training cyclists completed an ergometer based incremental exercise test and a 20-km time-trial. The HIT sessions were ~120 minutes in duration and consisted of matched volumes of 5, 10 and 20 second (short) or 15, 30 and 45 second (long) maximal intensity efforts. Results Both the short and long HIT regimes led to significant (p<0.05) gains in time trial performance compared to the control group. Relative to the control group, the mean changes (±90% confidence limits) in time-trial power were 8.2%±3.8% and 10.4%±4.3% for the short and long HIT regimes respectively; corresponding increases in peak power in the incremental test were 5.5%±2.7% and 9.5%±2.5%. Both HIT (short vs long) interventions led to non-significant (p>0.05) increases (mean ± SD) in VO2 peak (2.3%±4.7% vs 3.5%±6.2%), lactate threshold power (3.6%±3.5% vs 2.9%±5.3%) and gross efficiency (3.2%±2.4% vs 5.1%±3.9%) with only small differences between HIT regimes. Conclusions Seven days of overload HIT induces substantial enhancements in time-trial performance despite non-significant increases in physiological measures with competitive cyclists

- Description: The aim of this research was to provide a comparative analysis of the influence of behavioural alternatives, autonomy, competence and relatedness on participation in sport and physical activity for female adolescents within metropolitan and rural settings. Eighteen focus groups were conducted with a cross section of schools within metropolitan Melbourne and rural Victoria, Australia, involving 12-13-year olds and 15-16-year olds, using a semi-structured format. Content and thematic analyses were conducted on the data. Findings supported the sport commitment model by demonstrating that, in both rural and metropolitan settings, participation was influenced by the strength of commitment to a range of behavioural alternatives. Our findings also extended self-determination theory by suggesting that autonomy, competence, and relatedness were interrelated and their strength and influence on participation varied between settings. This study also has practical implications, including the promotion of more inclusive and supportive sports environments for female adolescents and promoting sport and physical activities as activity that promotes wellness, complements academic endeavours and reduces the stress of academic study. © 2011 Taylor & Francis.

- Description: This study explores a weekly community-based exercise program (CBEP) for ageing adults in Gippsland, Victoria, Australia. This program aims to improve the health and well-being of ageing adults and was evaluated using an exploratory qualitative study design. Four focus group discussions and two individual interviews were conducted before a thematic analysis using Braun & Clark's (2006) six-step approach. A total of 23 participants were involved in the study over a 6-week period. The thematic analysis resulted in two main themes: (a) meeting community needs and (b) benefits to health and well-being. Five minor themes stemmed from these two themes, in which participants identified that a service gap existed within the community and the program was adaptive in its design to meet community needs. Participants reported benefits to health and well-being, specifically perceived improved mobility and independence, social connections and ‘recharging the batteries to feel good’. The inclusion of Tai Chi exercises was noted for increased vitality and pain management benefits. The role of the exercise instructor was deemed to be instrumental to the success of the CBEP. The CBEP provides motivation for older adults to attend, increasing physical activity. Future CBEPs for ageing adults should provide a social component and relevant health education for participants. Exercises should be safely adapted by the exercise instructor to suit people of various abilities and to promote a more ‘inclusive’ environment. © 2021 John Wiley & Sons Ltd.

- Description: Physical inactivity continues to be a global issue with many adolescents and adults failing to meet the recommendations for daily exercise. Efforts to reduce physical inactivity in adults include the incorporation of strategies such as workplace physical activity programs, especially for sedentary workers. In this systematic literature review we examined current literature about the efficacy of workplace physical activity programs, as well as the barriers and enablers to these programs. Six EBSCO databases were searched (Academic Search Complete, CINAHL Complete, MEDLINE, APA PsycInfo, APA PsycArticles and SPORTDiscus with full text) between a ten year period (2011 to 2021). The search terms used were “physical activity”, “workplace” and “program” along with their variations. Following a systematic process, eighteen papers met the eligibility criteria. The authors analysed the findings using a narrative synthesis, in which four themes emerged from the data. These include Benefits to physical health, Benefits to mental health, Barriers to workplace physical activity and Workplace activity enablers. These findings provided several recommendations for organizations that endeavour to improve the health of workplace employees. Generalised workplace physical activity programs were viewed favourably by both employees and employers. Incorporating these practices into daily work structures may provide favourable outcomes such as increased work productivity and reduced physical inactivity. © 2023 The Author(s).
