Abstract: Exercise participation is important in overall health, but is not without risk, particularly when exercising at vigorous intensities. Pre-exercise screening procedures such as the Sports Medicine Australia Pre-Exercise Screening System (SMA PESS) aim to minimise risks while maximising benefits from physical activity. The purpose of this study was to evaluate the SMA PESS as it might be used within commercial fitness centres and to determine the effect of point of care blood analysis on risk identification. Convenience s le of participants attending fitness centres for exercise classes. Participants were recruited from commercial fitness centres and completed the PESS via self-administration and interview with an Exercise & Sports Science Australia Accredited Exercise Physiologist. Blood related risk factors obtained from the CardioChek(®) point of care blood analyser were compared to those obtained from laboratory analysis. Findings indicated that approximately 54% of participants would be required to seek medical clearance with a further 17% restricted to moderate intensity exercise. The identification of risk in Stage 2 of the SMA PESS improved with increasing rigour of application, with the number of participants classified as moderate risk increasing non-significantly from 37% to 50% (p=0.40). Increasing the rigour of administration of the SMA PESS influences risk identification and results in a higher number of clients being excluded from participation in vigorous intensity exercise.

Abstract: Wearable activity trackers can help older adults remain physically active. However, knowledge of the user experience during long-term use is scarce. Therefore, this study examined older adults’ experiences with, and perceptions of, wearable activity trackers combined with health professional feedback after a year’s use as part of a randomised controlled trial. Twenty older adults (73.6 ± 5.5 years) who had used a Jawbone UP24 activity tracker for 12 months during a randomised controlled trial were recruited for this study. All participants had at least one chronic condition. Acceptability data relating to activity tracker wear time was combined with focus group data to explore participants experiences of long-term activity tracker use. Data was analysed using thematic analysis. The activity tracker was well-accepted with the device worn on an average of 86% of possible days and participants reported an overall positive experience. Four themes were identified: (a) increased sense of awareness of activity levels is related to motivation (b) the level of engagement with the activity tracker influences the user experience (c) the role of feedback from a health professional in providing ongoing support d) the role of habits in supporting long-term behaviour change. The use of an activity tracker combined with health professional support can assist older adults to maintain their activity levels over 12 months. Consideration should be given to the previous technology experience of users and the design and accuracy of an activity tracker when recommending their use in a research or clinical setting.

Abstract: Despite a range of efforts to increase physical activity participation in Australia, inactivity levels in older adults have remained high over recent decades, contributing to increased rates of chronic health conditions. Lifestyle interventions, including telephone counseling (TC), improve physical activity participation and associated health outcomes over the short term however, ongoing feedback and support is required to maintain these changes. Newer technologies such as wearable activity trackers (ATs) may offer an alternative method for providing ongoing support. This study aims to investigate whether newer technologies such as wearable ATs assist in providing ongoing support to maintain physical activity levels and health outcomes. Older adults aged years who had just completed a 12-week face-to-face in idualized community exercise program in Tasmania, Australia, participated in the study. They were randomized to receive AT, TC, or usual care (UC). All groups received a home exercise program and an optional referral to a community-based exercise program. The AT group also received an AT and text message feedback from an accredited exercise physiologist (AEP). The TC group received phone calls from an AEP throughout the 12-month intervention. The primary outcome was daily steps measured by an ActivPAL (TM) accelerometer at baseline and at 3, 6, and 12 months. Secondary outcome measures included body composition, blood pressure, 10-time sit-to-stand (TTSTS) test, timed up and go test, and cardiorespiratory fitness. This trial was approved by the Tasmanian Health and Medical Human Research Ethics Committee (H0014713). A total of 117 participants were randomized to the study (AT, n=37 TC, n=38 UC, n=42). At baseline, the participants (75/117, 64.1% female mean age 72.4 years, SD 6.4) completed an average of 6136 steps (SD 2985) per day. Although there were no significant differences between groups, the TC and AT groups maintained daily step counts (mean difference [MD] −79 steps, 95% CI −823 to 663 steps P=.81 and MD −588 steps, 95% CI −1359 to 182 steps P=.09), and UC showed a reduction in daily steps (MD 981 steps, 95% CI −1668 to −294 steps P=.003) during the 12-month period. Diastolic blood pressure was significantly higher after AT than after UC (MD 5.62 mm Hg, 95% CI 1.30 to 9.94 mm Hg P=.01), and TTSTS was significantly slower on TC compared with UC (MD 2.36 seconds, 95% CI −0.14 to 4.87 seconds P=.03). The use of an AT with AEP support or TC is effective at maintaining daily step count in older adults over a 12-month period, suggesting that wearable ATs are as effective as TC. Further research to investigate which option is more cost-effective would be beneficial.

Abstract: he range of benefits associated with regular physical activity participation is irrefutable. Despite the well-known benefits, physical inactivity remains one of the major contributing factors to ill-health throughout industrialized countries. Traditional lifestyle interventions such as group education or telephone counseling are effective at increasing physical activity participation however, physical activity levels tend to decline over time. Consumer-based wearable activity trackers that allow users to objectively monitor activity levels are now widely available and may offer an alternative method for assisting in iduals to remain physically active. his review aimed to determine the effects of interventions utilizing consumer-based wearable activity trackers on physical activity participation and sedentary behavior when compared with interventions that do not utilize activity tracker feedback. systematic review was performed searching the following databases for studies that included the use of a consumer-based wearable activity tracker to improve physical activity participation: Cochrane Controlled Register of Trials, MEDLINE, PubMed, Scopus, Web of Science, Cumulative Index of Nursing and Allied Health Literature, SPORTDiscus, and Health Technology Assessments. Controlled trials of adults comparing the use of a consumer-based wearable activity tracker with other nonactivity tracker–based interventions were included. The main outcome measures were physical activity participation and sedentary behavior. All studies were assessed for risk of bias, and the Grades of Recommendation, Assessment, Development, and Evaluation system was used to rank the quality of evidence. The guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement were followed. A random-effects meta-analysis was completed on the included outcome measures to estimate the treatment effect of interventions that included an activity tracker compared with a control group. here was a significant increase in daily step count (standardized mean difference [SMD] 0.24 95% CI 0.16 to 0.33 P .001), moderate and vigorous physical activity (SMD 0.27 95% CI 0.15 to 0.39 P .001), and energy expenditure (SMD 0.28 95% CI 0.03 to 0.54 P=.03) and a nonsignificant decrease in sedentary behavior (SMD −0.20 95% CI −0.43 to 0.03 P=.08) following the intervention versus control comparator across all studies in the meta-analyses. In general, included studies were at low risk of bias, except for performance bias. Heterogeneity varied across the included meta-analyses ranging from low (I2=3%) for daily step count through to high (I2=67%) for sedentary behavior. tilizing a consumer-based wearable activity tracker as either the primary component of an intervention or as part of a broader physical activity intervention has the potential to increase physical activity participation. As the effects of physical activity interventions are often short term, the inclusion of a consumer-based wearable activity tracker may provide an effective tool to assist health professionals to provide ongoing monitoring and support.
