This study systematically examined the extent of environmental sustainability (ES) research within the sport-related journal sample of academic literature to identify areas of under-emphasis and recommend directions for future research. The data collection and analysis followed a content analysis framework. The investigation involved a total of 21 sport-related academic journals that included 4,639 peer-reviewed articles published from 1987 to 2008. Findings indicated a paucity of sport-ES research articles (n = 17) during this time period. Further analysis compared the sport-ES studies within the sample to research in the broader management literature. A research agenda is suggested to advance sport-ES beyond the infancy stage.

Although there is strong and consistent evidence that childhood and adolescent physical activity is osteogenic, the evidence concerning its sustained effects to adult bone health is not conclusive. Therefore the value of interventions, in addition to beneficial bone adaptation, could be exposure to activities children enjoy and therefore continue. As such, interventions should provide skills, pleasure, and supportive environments to ensure continued bone-strengthening physical activity with age. Until the dose-response as well as timing of physical activity to bone health is more fully understood, it is sensible to assume that physical activity is needed throughout the lifespan to improve and maintain skeletal health. Current federal guidelines for health-related physical activity, which explicitly recommend bone-strengthening physical activities for youth, should also apply to adults.

This study explores the strategies that experienced walkers felt were most useful for sustaining outdoor walking routines. To investigate this issue, a survey-based instrument was used in combination with a Conceptual Content Cognitive Mapping (3CM) exercise.
Seventy-one experienced walkers were asked to complete the 3CM exercise to explore the strategies that have helped them regularly walk outdoors. After 1 week these same individuals received a survey investigating these same issues as well as demographics and physical activity participation.
There was general agreement between 3CM and survey data with respect to the strategies used by experienced walkers. The most highly endorsed strategies involved using health goals and supportive walking environments. Survey results also revealed that those more likely to endorse the use of social support took fewer walks per week, but engaged in more nonwalking related physical activity.
Overall, the findings suggest that experienced walkers use a variety of strategies. Strategies such as focusing of the positive health outcomes, using attractive natural settings, and developing realistic action plans appeared to be the most useful. These results also indicate the 3CM technique may be an effective way to explore beliefs and motivations regarding physical activity.

The purpose of this study was to: (1) investigate how kinematic patterns are adjusted while running in footwear with THIN, MEDIUM, and THICK midsole thicknesses and (2) determine if these patterns are adjusted over time during a sustained run in footwear of different thicknesses. Ten male heel-toe runners performed treadmill runs in specially constructed footwear (THIN, MEDIUM, and THICK midsoles) on separate days. Standard lower extremity kinematics and acceleration at the tibia and head were captured. Time epochs were created using data from every 5 minutes of the run. Repeated-measures ANOVA was used (P < .05) to determine differences across footwear and time. At touchdown, kinematics were similar for the THIN and MEDIUM conditions distal to the knee, whereas only the THIN condition was isolated above the knee. No runners displayed midfoot or forefoot strike patterns in any condition. Peak accelerations were slightly increased with THIN and MEDIUM footwear as was eversion, as well as tibial and thigh internal rotation. It appears that participants may have been anticipating, very early in their run, a suitable kinematic pattern based on both the length of the run and the footwear condition.

This study assessed the influence of caffeine on metabolic and cardiovascular functions during sustained, light intensity cycling and at rest. Eight healthy, recreationally active adults participated in four randomly assigned, double-blind experimental trials of 60 min upright seated cycle exercise (30% VO2max) or equivalent rest with caffeine (5 mg ⋅ kg−1) or placebo consumed 60 min prior to data collection. Gas exchange was measured by open-circuit spirom-etry indirect calorimetry. Global blood flow was evaluated by thoracic impedance cardiography and arterial blood pressure by auscultation. A repeated measures ANOVA indicated that pretrial caffeine increased oxygen uptake and energy expenditure rate (p < 0.05) but did not change respiratory exchange ratio. Systolic, diastolic, and mean arterial blood pressure were elevated following caffeine intake (p < 0.05). Cardiac output, heart rate, stroke volume, and systemic vascular resistance were not significantly different between caffeine and placebo sessions. For each of the metabolic and hemodynamic variables examined, the effects of caffeine were similar during constant-load, light intensity cycling and at rest. These data illustrate that caffeine's mild thermogenic influence can be mediated without a major shift in substrate oxidation mixture. Caffeine at this dosage level alters cardiovascular dynamics by augmenting arterial blood pressure.

Children cite “fun” as the primary reason for participation in organized sport and its absence as the number-one reason for youth sport attrition. Therefore, the purpose of this study was to develop a theoretical framework of fun using a novel mixed-method assessment of participants in sport (FUN MAPS) via concept mapping.
Youth soccer players (n = 142), coaches (n = 37), and parents (n = 57) were stratified by age, sex, and competition level and contributed their ideas through (a) qualitative brainstorming, identifying all of the things that make playing sports fun for players; (b) sorting of ideas; and (c) rating each idea on its importance, frequency, and feasibility.
The FUN MAPS identify the 4 fundamental tenets of fun in youth sport within 11 fun-dimensions composed of 81 specific fun-determinants, while also establishing the youth sport ethos.
The FUN MAPS provide pictorial evidence-based blueprints for the fun integration theory (FIT), which is a multitheoretical, multidimensional, and stakeholder derived framework that can be used to maximize fun for children and adolescents to promote and sustain an active and healthy lifestyle through sport.

We reviewed and summarize the extant literature on associative/dissociative cognitive strategies used by athletes and others in circumstances necessitating periods of sustained attention. This review covers studies published since a prior publication by Masters and Ogles (1998), and, in keeping with their approach, offers a methodological critique of the literature. We conclude that the distinction between associative and dissociative strategies has outlived its usefulness since initially proposed in an earlier era of ground-breaking research by Morgan and Pollock (1977) that was influenced to some extent by psychodynamic thinking. In recent years there has been an evolutionary shift in concepts of sustained attention toward mindfulness—moment-by-moment attention—that has had a significant impact on conceptual models and clinical practice in diverse areas including stress management, psychotherapy, and athletic performance. We propose that future research on cognitive activity in sustained performance settings be embedded in a mindfulness-based conceptual model.
Citizens program, now known as 3 WINS Fitness ( www.3winsfitness.com ), based on the premise of involving students so they could understand the power they had to make world-altering change. The research is definitive. A program of community physical activity must be sustainable, accessible, and scalable

established school expectations ( Tinning, 1988 ). These future teachers will then have the opportunity to become sustainable practitioners who will employ authentic teaching approaches in line with promoting physical literacy and hopefully also influence the socialization process of future generations
3 WINS Fitness is a student-delivered free exercise program for the community delivered in public parks. We believe this program, which operates without external funding and has been sustained for 6 years, is one significant solution to reducing the level of physical inactivity in the United States. The operative 3 WINS in our program are participant health, community health, and student professional development. The primary focus has been underserved communities, and our current eight programs in Los Angeles, serve over 300 participants regularly. Three challenges to the program are student empowerment, faculty understanding and involvement, and establishing the relationship between university and parks, which represent a vital partnership. However, the accomplishment of undergraduate students having such a dynamic impact on public health underscores the need for encouraging this sustainable and innovative strategy to increase the physical activity levels of communities across America.
