Cardiovascular considerations on recreational scuba diving. SEC-Clinical Cardiology Association/SEC-Working Group on Sports Cardiology consensus document.

The practice of recreational scuba diving has increased worldwide, with millions of people taking part each year. The aquatic environment is a hostile setting that requires human physiology to adapt by undergoing a series of changes that stress the body. Therefore, physical fitness and control of cardiovascular risk factors are essential for practicing this sport. Medical assessment is not mandatory before participating in this sport and is only required when recommended by a health questionnaire designed for this purpose. However, due to the significance of cardiovascular disease, cardiology consultations are becoming more frequent. The aim of the present consensus document is to describe the cardiovascular physiological changes that occur during diving, focusing on related cardiovascular diseases, their management, and follow-up recommendations. The assessment and follow-up of individuals who practice diving with previous cardiovascular disease are also discussed. This document, endorsed by the Clinical Cardiology Association of the Spanish Society of Cardiology (SEC) and the SEC Working Group on Sports Cardiology of the Association of Preventive Cardiology, aims to assist both cardiologists in evaluating patients, as well as other specialists responsible for assessing individuals' fitness for diving practice.

The Association of Physical Activity and Urinary Incontinence in US Women: Results from a Multi-Year National Survey.

OBJECTIVES: To evaluate the relationships between physical activity, both work and recreational, and urinary incontinence among women. METHODS: We assessed women aged 20 years and older in 2008-2018 NHANES (National Health and Nutrition Examination Survey) cycles who answered self-reported urinary incontinence and physical activity questions. Weighted, multivariate logistic regression model was used to determine the association between incontinence and physical activity levels after adjusting for age, body mass index, diabetes, race, parity, menopause and smoking. RESULTS: A total of 30,213 women were included in analysis, of whom 23.15% had stress incontinence, 23.16% had urge incontinence, and 8.42% had mixed incontinence (answered "yes" to both stress and urge incontinence). Women who engaged in moderate recreational activity were less likely to report stress and urge incontinence (OR 0.79, 95% CI 0.62-0.99 and OR 0.66, 95% CI 0.48-0.90, respectively). Similarly, women who engaged in moderate activity work were less likely to report stress, urge and mixed incontinence (OR 0.84, 95% CI 0.70-0.99; OR 0.84, 95% CI 0.72-0.99; and OR 0.66 95% CI 0.45-0.97, respectively). CONCLUSIONS: Moderate physical activity and greater time spent participating in moderate physical activity are associated with a decreased likelihood of stress, urge and mixed incontinence in women. This relationship holds for both recreational and work-related activity. We hypothesize that the mechanism of this relationship is multifactorial, with moderate physical activity improving pelvic floor strength and modifying neurophysiological mediators (such as stress) involved in the pathogenesis of incontinence.

Promoting the Participation of Children and Adolescents With Disabilities in Sports, Recreation, and Physical Activity.

The benefits of physical activity are likely universal for all children, including children and adolescents with disabilities (CWD). The participation of CWD in physical activity, including adaptive or therapeutic sports and recreation, promotes inclusion, minimizes deconditioning, optimizes physical functioning, improves mental health as well as academic achievement, and enhances overall well-being. Despite these benefits, CWD face barriers to participation and have lower levels of fitness, reduced rates of participation, and a higher prevalence of overweight and obesity compared with typically developing peers. Pediatricians and caregivers may overestimate the risks or overlook the benefits of physical activity in CWD, which further limits participation. Preparticipation evaluations often include assessment of health status, functional capacity, individual activity preferences, availability of appropriate programs, and safety precautions. Given the complexity, the preparticipation evaluation for CWD may not occur in the context of a single office visit but rather over a period of time with input from the child's multidisciplinary team (physicians, coaches, physical education teachers, school nurses, adaptive recreation specialists, physical and occupational therapists, and others). Some CWD may desire to participate in organized sports to experience the challenge of competition, and others may prefer recreational activities for enjoyment. To reach the goal of inclusion in appropriate physical activities for all children with disabilities, child, family, financial, and societal barriers to participation need to be identified and addressed. Health care providers can facilitate participation by encouraging physical activity among CWD and their families during visits. Health care providers can create "physical activity prescriptions" for CWD on the basis of the child's preferred activities, functional status, need for adaptation of the activity and the recreational opportunities available in the community. This clinical report discusses the importance of participation in sports, recreation, and physical activity for CWD and offers practical suggestions to health care providers.

Grip Strength-Endurance in Ambitious and Recreational Climbers: Does the Strength Decrement Index Serve as a Feasible Measure?

The present study investigated the time course of repetitive maximal isometric grip strength, depending on the arm position, laterality (dominant vs. non-dominant side), and climbing level. The intervention aimed to provide a feasible indicator of maximal strength-endurance in climbing. Seventeen recreational (climbing level (CL): 6.8 (SD 0.5) on the Union Internationale des Associations d'Alpinisme (UIAA) metric scale) and eleven ambitious (CL: 8.7 (SD 0.6) UIAA metric scale) climbers (age: 27 (8) years; BMI: 21.6 (1.9) kg/m2; ape index (arm span divided by body height): 1.05 (0.18); training volume: 2.2 (1.0) h/week). Participants completed maximal isometric handgrip strength (Fmax) tests in four positions (left and right hand beside the trunk as well as left and right hand above the shoulder) plus twelve repetitive work-relief cycles, lasting 4 and 1 s where isometric strength, heart rate, and perceived exertion were recorded. Fmax differed between groups in nearly all positions. A large side × position × time × group interaction was observed for repetitive isometric grip strength (p = 0.009, ηp2 = 0.71). However, subsequent post-hoc tests did not reveal a significant difference between groups during each testing position. Additional correlation analysis between asymmetry and CL showed an inverse relationship for ambitious climbers (r = -0.71). In conclusion, the degree of grip strength decline did not relevantly differentiate between ambitious and recreational climbers. Thus, the time course of handgrip strength seems to mainly rely on maximal grip strength during the first contraction.

In search of a "vocabulary for recreation": Leisure-time physical activity among humanitarian migrants in regional Australia.

This study provides an exploration of the meanings of leisure for humanitarian migrants in regional Australia and these meanings' implications for health. It uses mixed-methods to explore leisure-time physical activity participation and day-to-day experiences of leisure and health. A sample representing approximately one third of the Coffs Coast adult humanitarian migrant population completed the survey, as well as 32 individuals who participated in interviews and focus groups. Findings were organised into three themes and explored issues around mental health and time for leisure, cultural differences in experiencing leisure, and the connections with experiences of other disadvantaged groups. We conclude by arguing that leisure needs to be brought to the fore of discussions around service provision and policy making concerned with the wellbeing of the refugee migrant population, particularly focusing on support for the (re)development of a vocabulary for recreation, as a step forward in the journey to healing and belonging.

From Cancer Rehabilitation to Recreation: A Coordinated Approach to Increasing Physical Activity.

Participation in adequate physical activity improves the health status of cancer survivors, enhances their survival, and reduces their risk of cancer recurrence. However, cancer survivors engage in low levels of physical activity and have limited access to rehabilitation services that could increase their participation. No optimal framework has been developed that supports physical activity participation among cancer survivors. Given the growth in numbers of cancer survivors, development of a framework may provide a pathway to facilitate timely and appropriate care. This perspective paper describes the development of the Cancer Rehabilitation to Recreation (CaReR) Framework and its practical implications. The CaReR Framework uses a tailored, stepped approach to guide health services and clinicians on the design and implementation of interventions to promote physical activity among cancer survivors. Implementation of the CaReR Framework will improve continuity and quality of care for cancer survivors and promote physical activity with the ultimate aim of improving health outcomes.

Calculation of Critical Speed from Raw Training Data in Recreational Marathon Runners.

INTRODUCTION: Critical speed (CS) represents the highest intensity at which a physiological steady state may be reached. The aim of this study was to evaluate whether estimations of CS obtained from raw training data can predict performance and pacing in marathons. METHODS: We investigated running activities logged into an online fitness platform by >25,000 recreational athletes before big-city marathons. Each activity contained time, distance, and elevation every 100 m. We computed grade-adjusted pacing and the fastest pace recorded for a set of target distances (400, 800, 1000, 1500, 3000, and 5000 m). CS was determined as the slope of the distance-time relationship using all combinations of, at least, three target distances. RESULTS: The relationship between distance and time was linear, irrespective of the target distances used (pooled mean ± SD: R = 0.9999 ± 0.0001). The estimated values of CS from all models were not different (3.74 ± 0.08 m·s), and all models correlated with marathon performance (R = 0.672 ± 0.036, error = 8.01% ± 0.51%). CS from the model including 400, 800, and 5000 m best predicted performance (R = 0.695, error = 7.67%) and was used in further analysis. Runners completed the marathon at 84.8% ± 13.6% CS, with faster runners competing at speeds closer to CS (93.0% CS for 150 min marathon times vs 78.9% CS for 360 min marathon times). Runners who completed the first half of the marathon at >94% of their CS, and particularly faster than CS, were more likely to slowdown by more than 25% in the second half of race. CONCLUSION: This study suggests that estimations of CS from raw training data can successfully predict marathon performance and provide useful pacing information.

Exploring perceived benefits, motives, barriers, and recommendations for prescribing yoga exercises as a nonpharmacological intervention for patients with epilepsy: A qualitative study from Palestine.

OBJECTIVES: Yoga is believed to play a role in stabilizing the electroencephalogram and the autonomic nervous system, thus might help control seizures in people with epilepsy (PWE). This qualitative study was conducted to explore experiences of Palestinian PWE with regard to benefits, motives, barriers, and recommendations of prescribing yoga exercises as a nonpharmacological intervention. METHODS: Purposive and snowball sampling techniques were used to recruit PWE who practiced yoga. Semi-structured in-depth interviews (n = 18) were conducted with the study participants. The interpretive description method was used to qualitatively analyze the data collected during the interviews. RESULTS: Following the thematic analysis adopted for this study, four major themes emerged. These themes were as follows: perceived benefits of yoga, motives to practice yoga, barriers to practice yoga, and recommendations on effective yoga practice for PWE. The perceived benefits included improvements in management of seizures, psychological, physical, and social well-being. People with epilepsy were motivated by the health benefits of yoga. Barriers of adherence to practice included personal and logistic factors. The interviewees recommended tailoring yoga sessions to the needs of PWE. CONCLUSION: This explorative qualitative study reported perceived benefits, motives, barriers, and recommendations of yoga as a nonpharmacological intervention for PWE. People with epilepsy used yoga as a beneficial nonpharmacological intervention to improve their health and reduce the negative effects of epilepsy on their physical and psychosocial well-being. Future studies are needed to investigate the health benefits of yoga when sessions are tailored to the needs of PWE.

Risk of hypoglycaemia associated with professional, recreational, and traffic-related activities in patients with type 2 diabetes: a cross-sectional study by questionnaire.

AIMS: We aimed to quantify the exposure to physical exercise associated with professional, recreational, or traffic-related activities in patients with type 2 diabetes, which may provoke or aggravate hypoglycaemic episodes, and to assess whether such risks determine the choice of medications minimizing the risk of hypoglycaemia. METHODS: In total, 203 patients with type 2 diabetes (98 women, 105 men, age 65 [56;72; median, inter-quartile range] years, diabetes duration 10 [5;15] years) were recruited from a German diabetes practice. A questionnaire assessed their engagement in professional, recreational, or traffic-related activities. The prescription insulin or sulphonylureas was quantified in relation to the number of such activities. RESULTS: 63.5% of the patients were treated with insulin, 7.4% with sulphonylureas, and 70.9% with either. Sixty-six patients (22.7%) were professionally active: 36 (54.4%) of those were professionally exposed to risky behaviour (14 [31.8%] patients with exposure to multiple risks and 20 (30.3%) who experienced hypoglycaemic episodes in the past year). In total, 194 (95.6%) patients were exposed to risky behaviour during recreational activities, 129 (63.6%) to multiple ones. All patients were exposed to traffic-related activities, 144 (70.9%) were exposed to more than being pedestrian, and 24 (11.8%) experienced hypoglycaemic episodes while in traffic. CONCLUSIONS: Patients with type 2 diabetes are exposed to risks associated with professional, recreational, and traffic-related activities. We recommend a careful assessment of such risks before glucose-lowering medications with a potential for provoking hypoglycaemic episodes are prescribed.

Sports nutrition for the recreational athlete.

BACKGROUND: Recreational sports participation provides many potential health benefits. However, some athletes experience medical problems associated with, or exacerbated by, a mismanagement of the relationship between their diet and sporting endeavours. OBJECTIVE: The aim of this article is to highlight recent developments in clinical sports nutrition, with a focus on providing evidence-based advice and resources for the management of common medical presentations. DISCUSSION: A low dietary energy intake relative to exercise energy demands (ie low energy availability) may result in an array of medical issues. An evidence-based framework for advice on sports supplements is available.

Understanding limitations in sport 1 year after an Achilles tendon rupture: a multicentre analysis of 285 patients.

PURPOSE: The purpose of this study was to determine patient-related and treatment-related predictors of superior and inferior function in sport and recreational activities 1 year after an Achilles tendon rupture. METHODS: This study is based on a multicentre cohort from 4 previous randomised controlled trials. All the patients who had responded to the Foot and Ankle Outcome Score (FAOS) at the 1-year follow-up were included. All the patients had a clinically verified Achilles tendon rupture and patients who underwent surgery were treated within 96 h of the time of rupture. Patients were excluded in the event of a previous Achilles tendon rupture or the presence of other lifestyle diseases. The primary outcomes of the study were reported in the 20th and 80th percentiles of the FAOS subscale, function in sports and recreational activities. RESULTS: A total of 285 (84% men) patients with an average age of 40.0 (SD 8.4) years were included. Smoking increased the odds of superior self-reported FAOS sport and recreation [OR 4.59 (95% CI 1.58-13.32), p = 0.005] compared with non-smoking, while being female [OR 0.38 (95% CI 0.16-0.93), p = 0.035] and every increment of one unit in BMI [OR 0.89 (95% CI 0.81-0.99), p = 0.029] reduced the odds. No variable was statistically significant when attempting to predict which patients report inferior FAOS sport and recreation. The recovery of symmetry in heel-rise tests had no effect on 1-year FAOS sport and recreation. Patient-reported outcomes had a good-to-excellent explanatory capacity of superior and inferior 1-year function in sport and recreational activities (AUC = 0.87-0.93). CONCLUSION: BMI is a modifiable risk factor, which, when lowered, may be associated with less impairment in sports 1 year after an Achilles tendon rupture. Females appear to perceive more limitations than males. Unexpectedly, smokers experience less limitations in foot and ankle function. Patients who report no functional limitation in sport are characterised by an overall perception of adequate foot, ankle and Achilles function, despite not having recovered symmetry in the heel-rise test. LEVEL OF EVIDENCE: I.

Recreational football is medicine against non-communicable diseases: A systematic review.

The purpose of this research was to conduct a systematic review of published articles related to the effect of recreational football on non-communicable diseases. A systematic review of Web of Science, SPORTDiscus, MEDLINE, and PubMed databases was performed according to PRISMA guidelines. Only empirical studies were included. There were no restrictions on the types of study design eligible for inclusion. The primary outcome measures result from the potential effects of recreational football on non-communicable diseases (eg, blood pressure, bone density, LDL cholesterol, and fat mass). A total of 44 articles met the inclusion criteria and were included. Recreational football is shown to: (a) decrease blood pressure and resting heart rate, improve cardiac structure and functioning, as well as increase maximal oxygen uptake in both sexes; (b) reduce cholesterol and triglycerides levels, increase insulin sensitivity, and have a positive impact on glycemic control; (c) improve bone mineralization, increase both bone mineral density and content, as well as acting as a stimulus for osteogenesis; and (d) be clearly beneficial for bone health, while slightly beneficial for body composition, muscle strength, and maximal oxygen uptake in adults with prostate cancer. The present systematic review demonstrated the benefits of recreational football practice on non-communicable diseases related to cardiovascular and bone health, body composition, type 2 diabetes, and prostate cancer. The effectiveness of recreational football on the aforementioned diseases may be related to age and gender; however, further research is required.

Physiological Demands of Trampolining at Different Intensities.

Purpose: The aim of this study was to examine the physiological demands of trampolining, in comparison with treadmill running, using a larger sample size and a wider range of physiological measures, than had been reported in the previous research. Method: Twenty-three healthy adults completed three, three-minute exercise bouts on both a trampoline and treadmill at different intensities. Heart rate (HR), oxygen consumption ([Formula: see text]), energy expenditure (EE) and blood lactate (BL) were collected for each bout. Results: Results of a two-way repeated measures MANOVA indicated that there was a significant difference between the modalities ([Formula: see text] = 9.3, p <.0005, [Formula: see text] = 0.39). A follow up two-way repeated measures ANOVA then identified that significant differences existed between the modalities for each of the variables; [Formula: see text] ([Formula: see text] = 159, p <.0005, [Formula: see text] = 0.88), EE (= 136, p <.0005, [Formula: see text] = 0.86) and BL ([Formula: see text] = 171, p <.0005, [Formula: see text] = 0.89). Subsequent post hoc testing found [Formula: see text] to differ significantly between the medium intensities (p =.01 d =0.6). EE to differ significantly for the medium (p =.003, d =-0.7) and high intensities (p =.02, d =-0.5). BL to differ significantly for the low (p =.04, d =0.4), medium (p =.03, d =0.5) and high (p =.001 d =1.4) intensities. Conclusions: The results from our study indicated that while significant differences do occur between running and trampolining for a given intensity, the trendline associated with each of the variables is similar. Therefore, monitoring the intensity of the session based the percentage of the participant's maximum heart rate, which is commonly used in running, may also be applied to trampolining.

Association of Food Access, Recreational Opportunities, and Natural Amenities with Engagement in the Veterans MOVE! Weight Management Program.

OBJECTIVE: The aim of this study was to examine the association of county-level food access, recreational opportunities, and natural amenities with participant engagement in a weight management program. METHODS: In this cohort study, participants in the Veterans Health Administration MOVE! weight management program between October 1, 2007, and September 30, 2013, were observed for 12 months after enrollment. Engagement was measured as the number of program visits per year at 12 months. Cross-sectional analysis and spatial regression were used to examine county characteristics associated with greater participant engagement at 12 months. RESULTS: A total of 321,624 participants in 2,708 counties were included. Greater engagement was associated with older age, female sex, white race, being married, and being retired. After accounting for similarities between nearby communities, engagement at 12 months was 3.1 visits higher for each additional farmers' market per 1,000 population (P = 0.01). Engagement was highest for participants living in counties with the most natural amenities (P < 0.001). Recreational opportunities had only a small effect on engagement in the program (ß = 0.02 visits at 12 months; P = 0.002). CONCLUSIONS: Consideration of a participant's county characteristics in addition to other known demographics and program factors may help to explain variation in engagement in weight management programs.

Transcranial Direct Current Stimulation for Online Gamers.

Transcranial direct current stimulation (tDCS) is a noninvasive brain stimulation technique that applies a weak electric current to the scalp to modulate neuronal membrane potentials. Compared to other brain stimulation methods, tDCS is relatively safe, simple, and inexpensive to administer. Since excessive online gaming can negatively affect mental health and daily functioning, developing treatment options for gamers is necessary. Although tDCS over the dorsolateral prefrontal cortex (DLPFC) has demonstrated promising results for various addictions, it has not been tested in gamers. This paper describes a protocol and a feasibility study for applying repeated tDCS over the DLPFC and neuroimaging to examine the underlying neural correlates in gamers. At baseline, individuals who play online games report average weekly hours spent on games, complete questionnaires on addiction symptoms and self-control, and undergo brain 18F-fluoro-2-deoxyglucose positron emission tomography (FDG-PET). The tDCS protocol consists of 12 sessions over the DLPFC for 4 weeks (anode F3/cathode F4, 2 mA for 30 min per session). Then, a follow-up is conducted using the same protocol as the baseline. Individuals who do not play online games receive only baseline FDG-PET scans without tDCS. Changes of clinical characteristics and asymmetry of regional cerebral metabolic rate of glucose (rCMRglu) in the DLPFC are examined in gamers. In addition, asymmetry of rCMRglu is compared between gamers and non-gamers at baseline. In our experiment, 15 gamers received tDCS sessions and completed baseline and follow-up scans. Ten non-gamers underwent FDG-PET scans at the baseline. The tDCS reduced addiction symptoms, time spent on games, and increased self-control. Moreover, abnormal asymmetry of rCMRglu in the DLPFC at baseline was alleviated after tDCS. The current protocol may be useful for assessing treatment efficacy of tDCS and its underlying brain changes in gamers. Further randomized sham-controlled studies are warranted. Moreover, the protocol can be applied to other neurological and psychiatric disorders.

Previous High School Participation in Varsity Sport and Jump-Landing Biomechanics in Adult Recreational Athletes.

CONTEXT: Early sports sampling is associated with superior biomechanics in youth athletes; however, the effect of multisport participation on adult biomechanics is unknown. OBJECTIVE: To compare jump-landing biomechanics between adult recreational athletes who previously participated in 0, 1, or 2 or more select high school varsity sports (VSs; basketball, lacrosse, soccer, volleyball) that feature landing and cutting tasks. DESIGN: Descriptive laboratory study. SETTING: University community setting. PATIENTS OR OTHER PARTICIPANTS: Fifty adult recreational athletes (22 women, 28 men; age = 23.8 ± 2.5 years) with no high school VS experience or with high school VS experience in basketball, lacrosse, soccer, or volleyball. Athletes were grouped into those who participated in 0 (0VS, n = 11), 1 (1VS, n = 21), or 2 or more (2VSs, n = 18) of these sports at the high school level. MAIN OUTCOME MEASURE(S): The average Landing Error Scoring System (LESS) total score from 3 individual jump landings was determined. A 1-way analysis of covariance using sex as the covariate was calculated to compare groups. The Pearson R was used to test for the correlation between the LESS score and number of sports played, and a linear regression analysis was performed using the number of sports played to predict the LESS score. The α level was set a priori at .05. RESULTS: The 0VS athletes produced similar LESS scores as the 1VS athletes (5.89 ± 1.2 versus 5.38 ± 1.93 points, respectively, P = .463), whereas the 2VSs athletes demonstrated lower LESS scores (3.56 ± 1.97 points) than the 0VS (P = .002) and 1VS (P = .004) athletes. The LESS scores were moderately negatively correlated with the number of high school VSs played (R2 = -0.491, P < .001). The linear regression analysis was significant (F1,37 = 9.416, P = .004) with R2 = 0.203. For every additional VS played at the high school level, the LESS score decreased by 1.28 points. CONCLUSIONS: Landing Error Scoring System scores were lower in athletes who had a history of multisport high school varsity participation in basketball, lacrosse, soccer, or volleyball compared with those who had a history of single-sport or no participation in these sports at this level. Multisport high school varsity participation in these sports may result in improved neuromuscular performance and potentially reduced injury risks as adults.

Make Them Move: Understanding Visitors' Sedentary Behavior in Protected Natural Areas. A Case Study in Spain.

BACKGROUND: Protected areas are important attractions for promoting healthy life habits. Consequently, to date, a number of studies have examined the association between visitors' characteristics and physical activities. However, little is known about the specific users inclined exclusively to have sedentary behavior during a visit. Thus, using the Alt Pirineu Natural Park (Spain) as a case study, the aim of this study is to determine the influence of sociodemographic, trip, motivational, and opinion descriptors on the likelihood of participating in sedentary behavior while visiting a protected natural area. METHODS: The data used were randomly collected from visitors through an onsite structured questionnaire (N = 628). RESULTS: Metabolic equivalent consumption was used to empirically distinguish the sedentary (22.6%) from the active (77.4%) visitor groups. A logistic regression analysis indicated that the trip and motivational descriptors explained the highest degree of the overall variation in reporting sedentary behavior. CONCLUSION: The study contributed to documenting the information about visitors' behavior in protected areas, and the findings may aid park managers in developing effective management strategies for promoting and enhancing physical activity in protected natural areas.

Normative, passionate, or problematic? Identification of adolescent gamer subtypes over time.

BACKGROUND AND AIMS: For most youngsters, gaming is a fun and innocent leisure activity. However, some adolescents are prone to develop problematic gaming behavior. It is therefore important to have a comprehensive understanding of psychosocial and game-related characteristics that differentiate highly engaged gamers from problematic gamers. To that end, this study evaluated the stability and consistency of Internet gaming criteria (as suggested by the DSM-5) and psychosocial characteristics in a two-wave longitudinal study including 1928 young adolescents (mean age = 13.3 years, SD = 0.91, 57% boys). METHODS: A confirmatory factor analysis revealed good stability of the Internet gaming disorder (IGD) construct over time. Latent class analyses revealed three classes for boys (recreational, engaged, and problematic) and two classes for girls (recreational and engaged). RESULTS: Significant differences between classes emerged for problem criteria (conflict and problems in social life), gaming duration, impulsivity, social competence, and attention/hyperactivity. The absence of a problematic gaming class for girls suggests that girls are less likely to develop problematic gaming behavior. DISCUSSION: The IGD criteria as proposed by the DSM-5 are a helpful tool to identify problematic gamers, although the results of this study suggest that using a strict cut-off point might result in false positives, particularly for boys. Problem criteria appeared to be the most sensitive and specific in identifying the problematic gamer, whereas escapism criteria were the least specific and sensitive. Careful consideration of the current proposed criteria to identify problematic gaming behavior could benefit the research and clinical field.

Improving Physical Activity and Outdoor Recreation in Rural Alabama Through Community Coalitions.

Obesity rates in the United States are trending upward, and disadvantaged populations continue to have disproportionate rates of obesity. In Alabama, the ALProHealth initiative used community-based participatory research to work with community coalitions to implement research-based interventions that addressed issues related to the lack of opportunities for physical activity in 14 counties whose populations are at high risk of obesity. Coalitions developed work plans and timelines for implementing interventions on the basis of issues discussed during focus groups at the beginning of the ALProHealth initiative. These 14 coalitions implemented 101 interventions related to physical activity in 16 communities. In this evaluation, we measured potential reach and improvements in amenities. The largest reach for an intervention was achieved through marketing and communication efforts, while the most popular intervention, undertaken by the largest number of communities, centered on installing or repairing playground equipment at community parks. Community-based participatory research is an effective method for addressing health issues at the local level, as interventions are developed and readily adopted through active partnerships with community leaders and residents.

If You Make it Free, Will They Come? Using a Physical Activity Accessibility Model to Understand the Use of a Free Children's Recreation Pass.

BACKGROUND: Children's sedentary lifestyles and low physical activity levels may be countered using population-level interventions. This study examines factors influencing the use of a free community-wide physical activity access pass for grade 5 students (G5AP). METHODS: A natural experiment with longitudinal data collection. A sample of 881 children completed the 9-month follow-up survey self-reporting where they used the G5AP. Two analyses were conducted: Getis-Ord GI* geographic cluster analysis of the spatial distribution of users, and logistic regression examining the relationship between use and accessibility (informational, economic, and geographic) and mobility options, while accounting for intrapersonal and interpersonal factors. RESULTS: Overall, 44.9% of children used the G5AP with clusters of high use in urban areas and low use in the suburbs. Other factors significantly related to G5AP included gender (girls), informational accessibility (active recruitment), economic accessibility (median household income), geographic accessibility (facilities within 1.6 km of home), and mobility options (access to Boys & Girls Club bus). CONCLUSIONS: This study found that a diverse population of children used the G5AP. To continue being successful, community-based physical activity interventions need to ensure that the intervention increases geographic, economic, and informational accessibility and provides mobility options that are available to the target population.
