Reporting Physical Activity: Perceptions and Practices of Australian Media Professionals

Ben J. Smith and Catriona M.F. Bonfiglioli

Background:

Advocacy informed by scientific evidence is necessary to influence policy and planning to address physical inactivity. The mass media is a key arena for this advocacy. This study investigated the perceptions and practices of news media professionals reporting physical activity and sedentariness to inform strategic communication about these issues.

Methods:

We interviewed media professionals working for major television, radio, newspaper and online news outlets in Australia. The interviews explored understandings of physical activity and sedentariness, attributions of causality, assignment of responsibility, and factors affecting news reporting on these topics. Data were thematically analyzed using NVivo.

Results:

Physical inactivity was recognized as pervasive and important, but tended to be seen as mundane and not newsworthy. Sedentariness was regarded as more novel than physical activity, and more likely to require organizational and environment action. Respondents identified that presenting these issues in visual and engaging ways was an ongoing challenge.

Conclusions:

Physical activity researchers and advocates need to take account of prevailing news values and media practices to improve engagement with the news media. These include understanding the importance of novelty, narratives, imagery, and practical messages, and how to use these to build support for environmental and policy action.

Prevalence of Total and Domain-Specific Physical Activity and Associated Factors Among Nepalese Adults: A Quantile Regression Analysis

Susan Paudel, Alice J. Owen, Stephane Heritier, and Ben J. Smith

Aim: To analyze the data from the World Health Organization Nepal STEPS survey 2013 to determine the prevalence of total and domain-specific physical activity (PA) and associated factors among Nepalese adults. Methods: A multistage cluster sampling technique was used to proportionately select participants from the 3 ecological zones (Mountain, Hill, and Terai) in Nepal. The Global PA Questionnaire was used to assess PA. The data were analyzed using quantile and ordinary least square regression. Results: Only 4% of the adults did not meet the World Health Organization PA guidelines. Age had a negative monotonic association with total PA and occupational PA, with the highest difference at the upper tails of the PA distribution. Lower total PA and occupational PA were associated with secondary or higher education, being retired or in unpaid employment, living in Terai or urban areas, and nonsmoking. Age, higher education, unpaid employment, and Terai or urban residence were negatively associated, while being currently married was positively associated with transport-related PA. Conclusion: Increasing age, higher education, unpaid employment, unemployment or retirement, and urban residence were associated with lower PA, with the stronger association at the upper tails of the distribution. The correlates had dissimilar associations across the quantiles of PA distribution.

Evaluating the Population Health Impact of Physical Activity Interventions in Primary Care—Are We Asking the Right Questions?

Elizabeth G. Eakin, Ben J. Smith, and Adrian E. Bauman

Background:

This article evaluates the extent to which the literature on primary care-based physical activity interventions informs the translation of research into practice and identifies priorities for future research.

Methods:

Relevant databases were searched for: (1) descriptive studies of physician barriers to physical activity counseling (n = 8), and (2) reviews of the literature on primary care-based physical activity intervention studies (n = 9). The RE-AIM framework was used to guide the evaluation.

Results:

Lack of time, limited patient receptiveness, lack of remuneration, and limited counseling skills are the predominant barriers to physical activity counselling. Issues of internal validity (i.e., effectiveness and implementation) have received much more attention in the literature than have issues of external validity (i.e., reach and adoption).

Conclusions:

The research agenda for primary care-based physical activity interventions needs greater attention to the feasibility of adoption by busy primary care staff, generalizability, and dissemination.

Effects of Carbohydrate Ingestion and Carbohydrate Mouth Rinse on Repeat Sprint Performance

Ben M. Krings, Timothy J. Peterson, Brandon D. Shepherd, Matthew J. McAllister, and JohnEric W. Smith

The purpose of this investigation was to examine to the influence of carbohydrate ingestion (CHOI) and carbohydrate mouth rinse (CHOR) on acute repeat maximal sprint performance. Fourteen healthy males (age: 21.7 ± 1.8 years, mass: 82.3 ± 12.3 kg) completed a total of five 15-s maximal repeat sprints on a cycle ergometer against 0.075 kg ・ kg-1 body mass each separated by 4 min of active recovery. Subjects completed four experimental trials and were randomly assigned one of four treatments: (1) CHOI, (2) CHOR, (3) placebo mouth rinse (PLAR), (4) placebo ingestion (PLAI). Subjects rinsed or ingested six 50 mL 10% CHO solutions throughout each trial. Performance variables measured included rating of perceived exertion, peak heart rate, peak and mean power output, fatigue index, and total work. Significant treatment main effects were observed for mean power output (p = 0.026), total work (p = 0.020), fatigue index (p = 0.004), and heart rate (p = 0.013). Overall mean power output and total work were significantly greater with CHOI (659.3 ± 103.0 watts, 9849.8 ± 1598.8 joules) compared with CHOR (645.8 ± 99.7 watts, 9447.5 ± 1684.9 joules, p < .05). CHOI (15.3 ± 8.6 watts/s) significantly attenuated fatigue index compared with CHOR (17.7 ± 10.4 watts/s, p < .05). Based on our findings, CHOI was more likely to provide a beneficial performance effect compared with CHOR, PLAI, and PLAR. Athletes required to complete repeat bouts of high intensity exercise may benefit from CHOI.

The Built Environment and Population Physical Activity: Methods for Mapping the Relevant Laws

Tracy Nau, William Bellew, Billie Giles-Corti, Adrian Bauman, and Ben J. Smith

Background: The development of policies that promote and enable physical activity (PA) is a global health priority. Laws are an important policy instrument that can enable enduring beneficial outcomes for individuals, organizations, and environments through multiple mechanisms. This article presents a systematic process for mapping laws relevant to PA, which can be used to understand the role of laws as a powerful PA policy lever. Methods: Building on methods used in public health law research, we developed a protocol for scientific mapping of laws influencing the built environment for PA in Australia. The MonQcle online legal research platform was used for data coding, analysis, and presentation. Results: We describe the 10 key stages of legal mapping that we applied to examine state and territory laws that influence walking and cycling in Australia. Conclusions: Law is a neglected element of policy research for PA. There is a need for accessible legal data to drive the design, investment, and implementation of legal interventions to improve population PA. Legal mapping is a first step toward evaluation of such laws for PA. This paper provides a practical case study and guidance for the 10 stages in legal mapping of laws that influence the built environment for PA.

Whole of Systems Approaches to Physical Activity Policy and Practice in Australia: The ASAPa Project Overview and Initial Systems Map

William Bellew, Ben J. Smith, Tracy Nau, Karen Lee, Lindsey Reece, and Adrian Bauman

Background: The literature on whole of system approaches (WSAs) has been largely theoretical in focus. The Australian Systems Approaches to Physical Activity is a national project designed to contribute a practical implementation focus to such approaches at the population level. Methods: National meetings were convened with federal and state government sector stakeholders to identify physical activity (PA) related policies and programs. Policies and programs were audited to develop an understanding of the existing PA system. A WSA conceptual map for PA was developed using feedback from system stakeholders, existing WSAs, and related work in obesity. Results: Completion of the policy audit has revealed key areas of need regarding policy governance, coordination, financing, and evaluation. An initial WSA conceptual map for Australia has been developed incorporating governance, translation, and advocacy. Stakeholder co-production of an integrated framework for PA and design plans for a community of practice knowledge hub has commenced. Conclusions: In Australia, Australian Systems Approaches to Physical Activity project partners have developed a conceptual whole of systems map that is guiding progress beyond the theoretical to application in the real world: a national PA policy audit, co-production of an integrated PA policy framework, and planning for a PA community of practice knowledge hub.

Effects of Carbohydrate Mouth Rinsing on Upper Body Resistance Exercise Performance

Ben M. Krings, Brandon D. Shepherd, Hunter S. Waldman, Matthew J. McAllister, and JohnEric W. Smith

Carbohydrate mouth rinsing has been shown to enhance aerobic exercise performance, but there is limited research with resistance exercise (RE). Therefore, the purpose of this investigation was to examine the effects of carbohydrate mouth rinsing during a high-volume upper body RE protocol on performance, heart rate responses, ratings of perceived exertion, and felt arousal. Recreationally experienced resistance-trained males (N = 17, age: 21 ± 1 years, height: 177.3 ± 5.2 cm, mass: 83.5 ± 9.3 kg) completed three experimental sessions, with the first serving as familiarization to the RE protocol. During the final two trials, the participants rinsed a 25-ml solution containing either a 6% carbohydrate solution or an artificially flavored placebo in a randomized, counterbalanced, and double-blinded fashion. The participants rinsed a total of nine times immediately before beginning the protocol and 20 s before repetitions to failure with the exercises bench press, bent-over row, incline bench press, close-grip row, hammer curls, skull crushers (all completed at 70% one-repetition maximum), push-ups, and pull-ups. Heart rate, ratings of perceived exertion, and felt arousal were measured at the baseline and immediately after each set of repetitions to failure. There were no differences for the total repetitions completed (carbohydrate = 203 ± 25 repetitions vs. placebo = 201 ± 23 repetitions, p = .46, Cohen’s d = 0.10). No treatment differences were observed for heart rate, ratings of perceived exertion, or felt arousal (p > .05). Although carbohydrate mouth rinsing has been shown to be effective in increasing aerobic performance, the results from this investigation show no benefit in RE performance in resistance-trained males.

Dietary Intakes of Elite 14- to 19-Year-Old English Academy Rugby Players During a Pre-Season Training Period

Deborah R. Smith, Ben Jones, Louise Sutton, Roderick F.G.J. King, and Lauren C. Duckworth

Good nutrition is essential for the physical development of adolescent athletes, however data on dietary intakes of adolescent rugby players are lacking. This study quantified and evaluated dietary intake in 87 elite male English academy rugby league (RL) and rugby union (RU) players by age (under 16 (U16) and under 19 (U19) years old) and code (RL and RU). Relationships of intakes with body mass and composition (sum of 8 skinfolds) were also investigated. Using 4-day diet and physical activity diaries, dietary intake was compared with adolescent sports nutrition recommendations and the UK national food guide. Dietary intake did not differ by code, whereas U19s consumed greater energy (3366 ± 658 vs. 2995 ± 774 kcal·day-1), protein (207 ± 49 vs. 150 ± 53 g·day-1) and fluid (4221 ± 1323 vs. 3137 ± 1015 ml·day-1) than U16s. U19s consumed a better quality diet than U16s (greater intakes of fruit and vegetables; 4.4 ± 1.9 vs. 2.8 ± 1.5 servings·day-1; nondairy proteins; 3.9 ± 1.1 vs. 2.9 ± 1.1 servings·day-1) and less fats and sugars (2.0 ± 1. vs. 3.6 ± 2.1 servings·day-1). Protein intake vs. body mass was moderate (r = .46, p < .001), and other relationships were weak. The findings of this study suggest adolescent rugby players consume adequate dietary intakes in relation to current guidelines for energy, macronutrient and fluid intake. Players should improve the quality of their diet by replacing intakes from the fats and sugars food group with healthier choices, while maintaining current energy, and macronutrient intakes.

Associations of Type, Organization, and Number of Recreational Activities With Total Activity

Heather R. Bowles, Dafna Merom, Tien Chey, Ben J. Smith, and Adrian Bauman

Background:

The aim of this study was to examine the associations between characteristics of recreational activity and total physical activity (PA).

Methods:

Recreational activity type and number were assessed for 3,385 adult respondents to the population-based Exercise Recreation and Sport Survey and categorized as “no recreational activity,” “walking only,” “sport only,” or “combined walking and sport.” Total PA was assessed by the International Physical Activity Questionnaire and categorized as “low,” “moderate,” or “high.”

Results:

Odds of high total PA were 1.7 times greater among walking-only participants, 2.9 times greater among sport-only participants, and 3.3 times greater among participants in combined walking and sport compared to no recreational activity participants. Greater number of recreational activities related to increased odds of high total PA. Similar associations were observed between recreational activity and moderate total PA.

Conclusion:

Participants in more than one type of recreational activity were less likely to have a low-active lifestyle.
