Background Physical activity (PA) is a component of cardiac rehabilitation (CR). However, life-long engagement in PA is required to maintain benefits gained. Wearable PA monitoring devices (WPAM) are thought to increase PA. There appear to be no reviews which investigate the effect of WPAM in cardiac populations. We firstly aimed to systematically review randomised controlled trials within the cardiac population that investigated the effect WPAM had through the maintenance phase of CR. We specifically examined the effect on cardiorespiratory fitness (CRF), amount and intensity of daily PA, and sedentary time. Secondly, we aimed to collate outcome measures reported, reasons for drop out, adverse events, and psychological impact from utilising a WPAM. Methods A systematic search (up to January 2019) of relevant databases was completed, followed by a narrative synthesis, meta-analysis and qualitative analysis. Results Nine studies involving 1,352 participants were included. CRF was improved to a greater extent in participants using WPAM with exercise prescription or advice compared with controls (MD 1.65 mL/kg/min;95% confidence interval [CI; 0.64–2.66]; p = 0.001; I 2 = 0%). There was no significant between group difference in six-minute walk test distance. In 70% of studies, step count was greater in participants using a WPAM with exercise prescription or advice, however the overall effect was not significant (SMD 0.45;95% [CI; − 0.17-1.07] p = 0.15; I 2 = 81%). A sensitivity analysis resulted in significantly greater step counts in participants using a WPAM with exercise prescription or advice and reduced the heterogeneity from 81 to 0% (SMD 0.78;95% [CI;0.54–1.02]; p < 0.001; I 2 = 0%). Three out of four studies reporting on intensity, found significantly increased time spent in moderate and moderate-vigorous intensity PA. No difference between groups was found for sedentary time. Three of six studies reported improved psychological benefits. No cardiac adverse events related to physical activity were reported and 62% of non-cardiac adverse events were primarily musculoskeletal injuries. Reasons for dropping out included medical conditions, lack of motivation, loss of interest, and technical difficulties. Conclusions Our meta-analysis showed WPAM with exercise prescription or advice are superior to no device in improving CRF in the maintenance phase of CR and no cardiac adverse events were reported with WPAM use. Our qualitative analysis showed evidence in favour of WPAM with exercise prescription or advice for both CRF and step count. WPAM with exercise prescription or advice did not change sedentary time. Psychological health and exercise intensity may potentially be enhanced by WPAM with exercise prescription or advice, however furthe...

Although survival rates continue to improve for many cancers (Australian Institute of Health and Welfare, 2016), cancer treatments (e.g., surgery, hormonal therapy, radiation therapy, chemotherapy) can contribute to acute, late-term, and long-term side effects. These treatments may negatively alter patients' body composition and physical function, leading to increased risk of other orthopedic and cardiovascular conditions (

ObjectivesTo assess awareness of external auditory exostosis (EAE) among Australian surfers.MethodsThis is a cross-sectional observational study, assessing professional and recreational Australian surfers. Currently, active surfers over 18 years of age, surfing year-round, were eligible to participate. After initial screening, individuals were asked to complete a questionnaire. All included volunteers underwent bilateral otoscopic examination, to assess the presence and severity of EAE.ResultsA total of 113 surfers were included in the study and were divided into two groups, based on surfing status: 93 recreational surfers and 20 professional surfers. Recreational surfers were significantly older (p<0.005), more experienced (greater years surfing; p<0.005), with lower prevalence of otological symptoms (p<0.05). The most common symptoms were water trapping, impacted wax and hearing loss. Prevalence of EAE was high for both groups (95% in the professional surfers and 82.8% in the recreational surfers); however, recreational surfers had mild grade EAE (grade 1) as the most common presentation, as opposed to professionals who had severe grade EAE (grade 3) as the most common presentation (p<0.05 between groups). Awareness of the term ‘surfer’s ear’ was high for both groups, as was knowledge of prevention options. However, fewer considered the condition to be preventable, and an even lower number reported regular use of prevention methods.ConclusionAustralian surfers had a high level of awareness of EAE; however, few reported using prevention methods, despite having a high prevalence of the condition. Health practitioners should screen susceptible individuals in order to recommend appropriate preventive measures.

Background Surfing is a popular sport in Australia, accounting for nearly 10% of the population. External auditory exostosis (EAE), also referred to as surfer’s ear, is recognized as a potentially serious complication of surfing. Cold water (water temperature below 19 °C) is a commonly cited risk factor, with prevalence of EAE in cold water surfers ranging from 61 to 80%. However, there is a paucity of studies reporting the prevalence of EAE in surfers exposed to water temperatures above 19 °C. With mean water temperature ranging from 19 °C to 28 °C, the Gold Coast region of Australia provides the ideal environment to assess the main goal of this study: to assess the prevalence and severity of EAE in warm water surfers. Methods Eligible participants were surfers living and surfing on the Gold Coast (Queensland, Australia). Currently active surfers over 18 years of age, surfing year-round, with a minimum of five consecutive years of surfing experience were recruited to participate. Included individuals were asked to complete a questionnaire and underwent bilateral otoscopy. Results A total of 85 surfers were included, with mean age 52.1 years (standard deviation [SD] ±12.6 years) and mean surfing experience of 35.5 years (SD ±14.7 years). Nearly two-thirds of participants (65.9%) had regular otological symptoms, most commonly water trapping (66%), hearing loss (48.2%), and cerumen impaction (35.7%). Less than one-fifth of the surfers (17.7%) reported regular use of protective equipment for EAE. The overall prevalence of exostosis was 71.8%, with most of the individuals having bilateral lesions (59%) and a mild grade (grade 1, 47.5%). There was insufficient evidence for any significant associations between the main outcomes (presence and severity of EAE) and factors related to age, surfing experience, winter exposure, surfing ability, symptoms, and use of protective equipment. Conclusion To the best of our knowledge, this is the first study assessing EAE in surfers exposed to warm waters (above 19 °C). The prevalence of 71.8% highlights the high prevalence of the condition in the surfing population, regardless of water temperature. Future research should focus on ways to prevent EAE.

ABSTRACT. The purpose of this study was to examine the validity of the American College of Sports Medicine's (ACSM) prediction equations for calculating peak oxygen consumption (VO2max) in young adults with mental retardation. A total of 32 subjects with mental retardation participated in this study: 15 young adults with Down's syndrome (DS) and 17 non‐DS young adults (NDS). Subjects were matched for age, gender and intelligence quotient (IQ). Subjects were given a standard treadmill‐graded exercise test to determine peak heart rate (HR) and peak oxygen consumption (VO2max). Subjects were connected to a metabolic cart during the test. Peak VO2 was predicted using ACSM's prediction equations where predicted VO2max is: men, 57.8–0.445 (age); and women, 42.3–0.356 (age). Statistical significance between groups was determined using a two‐tail t‐test, with alpha set a priori at 0.05. The DS group had a significantly (P=0.0003) lower peak HR(DS 155.90 ± 12.12 vs NDS 175.38±9.87) and per cent HR achieved (P=0.0007) (DS 80.26±6.76 vs NDS 89.39±4.46) as compared to the NDS group. Differences were also found between groups with respect to peak oxygen consumption. The DS had a significahtly (P=0.006) lower peak oxygen uptake (ml kg(−1) min(−1) as compared to the NDS group (23–68±4.01 vs 31.00±7.11, respectively). Significant differences (P=0.007) were accordingly observed with respect to per cent predicted oxygen uptake achieved (DS 55.22± 10.61 vs NDS 73.27±19.15). A nearly two‐fold difference (P=0.01) was observed with respect to the functional aerobic impairment between the DS (44.79±10.61)and NDS (28.29±18.63) groups, further illustrating the impaired peak cardiovascular capacities of both groups. The results of this study indicated that use of the ACSM gender and activity specific prediction equations in young adults with mental retardation (DS and NDS), peak VO2 is significantly over‐predicted (83.9 and 39.2%, respectively). Therefore, peak oxygen consumption and derived exercise prescriptions must be based on actual measurements, rather than via ACSM prediction equations. Otherwise, training intensities may be over‐predicted and impose possible health risks.

Background The feasibility and benefits of a 24-week targeted progressive supervised resistance and weight-bearing exercise programme (Group Aged Care Exercise + GAIT (GrACE + GAIT)) in the residential aged care (RAC) setting was investigated as very little peer-reviewed research has been conducted in relation to exercise programmes of this duration in this cohort. Methods A quasi-experimental study design consisting of two groups (control and exercise) explored a 24-week targeted progressive supervised resistance and weight-bearing exercise programme (GrACE + GAIT) in two RAC facilities in Northern New South Wales, Australia. A total of 42 adults consented to participate from a total of 68 eligible residents (61.7%). The primary outcome measures were feasibility and sustainability of the exercise programme via intervention uptake, session adherence, attrition, acceptability and adverse events. Secondary measures included gait speed and the spatio-temporal parameters of gait, handgrip muscle strength and sit to stand performance. Results Twenty-three residents participated in the exercise intervention (mean (SD) 85.4 (8.1) years, 15 females) and 19 in the control group (87.4 (6.6) years 13 females). Exercise adherence was 79.3%, with 65% of exercise participants attending ≥70% of the sessions; 100% of those originally enrolled completed the programme and strongly agreed with the programme acceptability. Zero exercise-related adverse events were reported. ANCOVA results indicated that post-intervention gait speed significantly increased (p < 0.001) with an 18.8% increase in gait speed (m/s). Discussion The GrACE + GAIT programme was shown to be feasible and significantly improve adults living in RAC facilities gait speed, handgrip strength and sit to stand performance. These results suggest that the GrACE + GAIT programme is suitable for use in the RAC sector and that it has the potential to reduce disability and improve function and quality of life of the residents.

BackgroundMasters athletes (MAs) have led a physically active lifestyle for an extended period of time or initiated exercise/sport in later life. Given the benefits of physical activity and exercise we investigated if body mass index (BMI), an indirect health indicator of obesity, was clinically superior in MAs as compared to controls or the general population.MethodsSeven databases (Medline, PubMed, Scopus, Web of Science, CINAHL, PsycINFO, Cochrane) were electronically searched for studies on BMI (kg/m2) or as a percentage of BMI categories (underweight, normal, overweight, obesity) in MAs.ResultsOf the initial yield of 7,431 papers, 60 studies met our inclusion criteria and were used in this literature review. Studies identified were classified as: endurance sports (n = 14), runners (n = 14), mixed sports (n = 8), cyclists (n = 4), soccer (n = 4) swimmers (n = 3), non-specific (n = 3), orienteering (n = 2), World Masters Games (n = 2) and individual sports (n = 5). Where BMI was presented for the group of MAs the mean was 23.8 kg/m2 (± 1.1) with a range from 20.8 kg/m2 (endurance runners) to 27.3 kg/m2 (soccer players), this was significantly lower (p < 0.001) than controls ( −9.5%, 26.13 ± 1.7 kg/m2). Where gender specific BMI was reported the mean for male MAs was 23.6 kg/m2 (± 1.5) (range 22.4 kg/m2 endurance to 26.4 kg/m2 swimmers) and 22.4 kg/m2 (± 1.2) for female MAs (range 20.8 kg/m2 mixed to 24.7 kg/m2 WMG).ConclusionIn most, but not all studies the BMI of MAs was significantly lower than controls. A clinically superior BMI affords MAs reduced risk with regard to a number of cardiometabolic diseases, osteoarthritis and certain types of cancers.
