Unobtrusive Observation of Caregiver-Child Pairs at Public Pools and Playgrounds: Implications for Child Unintentional Injury Risk

This study aimed to determine and compare the nature of supervision children received in two settings that have different levels of environmental risk, an aquatic setting (public pools) and a non-aquatic setting (playground). An observational design was implemented to examine caregiver and child behaviors at six indoor public pools and four playgrounds. Chi-square tests of homogeneity were conducted to determine associations between caregiver and child variables. Pre-school children received significantly higher levels of supervision than school aged children in both settings. For school aged children the level of supervision varied between settings, with children significantly more likely to be unsupervised in public pools and poorly supervised in playgrounds. Reasons for the lack of supervision in aquatic settings remain unclear, particularly as this setting was considered to be of higher environmental risk, because drowning rates are high for young children. Because evidence indicates inadequate supervision is common in aquatic settings, further investigations are required to identify ways to promote closer supervision practices, and determine caregiver perceptions regarding their responsibilities when supervising young children in aquatic settings

Self-Reported Supervisory Behavior and Belief vs. Actual Observations of Caregiver Behavior at Beaches

This study examined self-reported supervisory behaviours of caregivers at beaches and ascertained whether self-reported supervision reflects observed behaviour. Observations were conducted of caregiver/child pairs at 18 Australian beaches, with questionnaires subsequently completed by caregivers. Caregivers identified visual contact as essential for close supervision and proximity a key determinant in distinguishing supervision and close supervision. Supervisory behaviour was associated with child age, whilst lifeguard patrol had no effect on supervision. All supervision statements from the PSAPQ-BEACH were associated with supervision. Only three statements were significant independent predictors of supervision. Comparisons suggest caregivers’ self-reported supervisory behaviour reflects actual supervision. As this is the first study of its kind, it is essential that further prospective research using mixed-method approaches build on this information

Home Swimming Pool Design to Improve Diving Safety

This study sought to establish home swimming pool design guidelines to minimize risk of diving injury. Using a qualitative design, interviews with representatives of home pool companies were analyzed and common themes were determined. Pool company display centers and advertising materials were also examined. The typical in-ground fiberglass home pool was described by manufacturers as 8m in length, with a constant gradient of 0.9m to 1.8–2.0m deep. Comparisons between this profile and the underwater pathways of young adults in previous studies by the authors showed that, if the dives had been performed in this typical pool, impact would have occurred for some dives. Safety features such as depth markings and signage were absent from all pools. We concluded that recreational swimmers with limited diving skills are at risk of diving injury in the typical home swimming pool. Recommendations are provided of strategies that can be implemented by home pool owners to improve pool safety

Predicting Young Adults’ Intentions and Involvement in Alcohol-Influenced Aquatic Activity

Globally, alcohol consumption is a public health issue and a risk factor for drownings among young adults. While studies have identified a prominence of alcohol in youth drownings, little is known about the factors that influence young adults’ involvement in alcohol-influenced aquatic activity. The current study aimed to identify the predictors of young adults’ intention to participate, and past participation, in alcohol-influenced aquatic activity. A reliable and valid survey, informed by the Theory of Planned Behavior, was distributed to young adults (aged 18-24 years) educated in the UK and Australia. Cumulative odds ordinal logistic regressions with proportional odds were conducted to establish predictors. Overall, 182 participants completed the survey. Subjective norms (Wald χ2 (2) = 8.43, p = .015), cognitive attitudes (Wald χ2 (2) = 6.40, p = .041) and previous involvement (χ2 (1) = 8.98, p = .003) were significant predictors of intention, whilst the influence of friends (Wald χ2 (2) = 10.99, p = .004) and intention (Wald χ2 (2) = 10.80, p = .005) were significant predictors of behavior. Practitioners should enhance risk awareness and norm perceptions in prevention programs to encourage informed decision making in social aquatic situations

Swim Instructor Beliefs About Toddler and Pre-School Swimming and Water Safety Education

To study the teacher component of the parent-teacher-learner triad in preschool aquatics and explore compatibility of instructor messages with current drowning prevention beliefs, 133 preschool aquatics instructors were surveyed. Instructors with basic swim teacher accreditation and those with a preschool/infant instructor extension (“Extension”) were compared. More Extension instructors selected “safety” as an important outcome (χ2 = 7.907, df = 3, p = 0.048). Both instructor groups considered parental education important but Extension instructors held this view more strongly. Disturbingly, more Extension instructors disagreed that increased toddler confidence following lessons necessitates greater supervision around water (χ2 = 4.141, df = 1, p = 0.042). To avoid such messages, instructor education should place even greater emphasis on close and constant adult supervision and counter the misconception that early age lessons protect children from drowning

Can You Swim? Self-Report and Actual Swimming Competence Among Young Adults in Ballarat, Australia

This paper reports the Australian findings in an international study comparing self-reported and actual swimming and aquatic skills of young adults. Physical Education and Sports Sciences students (n=263) completed the “Can You Swim?” self-report survey and practical skills assessment, unaware that the practical tests replicated survey items. Relationships for comparisons between practical tests and their matched survey item were weak, indicating participants had inaccurate perceptions of their own swimming skills. Typically, they underestimated their competence in terms of distance and fundamental aquatic skills. Understanding of what constitutes different levels of swimming ability was poor, for example, most participants identified as average or good to excellent swimmers, but more than half of self-identified average swimmers, and 20% of good to excellent swimmers, estimated they could complete \u3c100m of continuous swimming. The implications of study findings for drowning prevention and the need for further research are discussed

Treadmill velocity best predicts 5000-m run performance

In this study, we aimed to investigate physiological determinants of endurance performance that best predict 5000-m average run velocity before and after endurance training. Thirty-nine previously untrained participants completed a 5000-m run; a constant velocity test (measuring running economy); and an incremental treadmill test to determine maximal oxygen uptake, final treadmill velocity, and velocity and oxygen uptake at lactate threshold, before and after six weeks of endurance training. Maximal oxygen uptake, final treadmill velocity, and velocity and oxygen uptake at threshold all increased significantly after training (p < 0.05). Average velocity for 5000m increased significantly (p < 0.05). Running economy was not significantly altered. Correlation analysis revealed final treadmill velocity was most strongly related to 5000-m performance, in both untrained and trained states (r = 0.89, 0.83). Lactate threshold velocity (r = 0.73, 0.76), maximal oxygen uptake (r = 0.55, 0.51) and oxygen uptake at threshold (r = 0.45, 0.45) also showed significant correlations. In contrast, running economy was not significantly related to performance. These results demonstrate that final treadmill velocity in an V̇O2max test is the single best predictor of 5000-m performance in untrained and trained states. Furthermore, stepwise regression analysis showed that only velocity at lactate threshold significantly improved the accuracy of prediction provided by final treadmill velocity alone. © Georg Thieme Verlag KG Stuttgart
