A growing body of research has illuminated beneficial effects of a single bout of physical activity (i.e., acute exercise) on cognitive function in school-age children. However, the influence of acute exercise on preschoolers’ cognitive function has not been reported. To address this shortcoming, the current study examined the effects of a 30-min bout of exercise on preschoolers’ cognitive function. Preschoolers’ cognitive function was assessed following a single bout of exercise and a single sedentary period. Results revealed that, after engaging in a bout of exercise, preschoolers exhibited markedly better ability to sustain attention, relative to after being sedentary (p = .006, partial eta square = .400). Based on these findings, providing exercise opportunities appears to enhance preschoolers’ cognitive function.

Community engagement is commonly imbedded in the ethos of institutions of higher education and has been identified as a High Impact Practice for student learning and retention. The Sustained Engagement Experiences in Kinesiology (SEEK) program at the University of La Verne is a curriculum-wide approach that moves students through four stages of community engagement: Respect, Participating with Effort, Self-Directions, and Leadership. The stages are developmentally sequenced across the curriculum and provide opportunities for learners to move from passive participants to active engagement scholars. The engagement experiences serve to enhance students’ abilities to transfer what they learn in the classroom to real-life problems, foster an asset-based approach to community engagement, and facilitate a transition from surface-to deep-learning.

Individuals with autism often lack motivation to engage in sustained physical activity. Three adolescents with severe autism participated in a 16-week program and each regularly completed 30 min of cycling at the end of program. This study investigated the effect of a self-regulation instructional strategy on sustained cycling, which included self-monitoring, goal setting, and self-reinforcement. Of particular interest was the development of self-efficacy during the physical activity as a mediator of goal setting. A multiple baseline changing criterion design established the effectiveness of the intervention. The results suggest that self-regulation interventions can promote sustained participation in physical activity for adolescents with severe autism.

This study was a retrospective analysis of injuries sustained by women (mean age 60.9) who completed a 24-week walking intervention. We hypothesized that those who walked 60 min, 5 days/week (n = 27) were more likely to have an injury than those who walked 3 days/week (n = 27), and that predisposing conditions would lead to more injuries. We also examined the effect of the initial 4 weeks’ walking progression on likelihood of injury. A total of 12% of the walkers reported injuries necessitating program withdrawal, 18% reported minor injuries, and 26% reported injuries requiring medical treatment. Age, weight, cardiovascular fitness level, and walking volume were not significantly related to injuries. Women with prior musculoskeletal conditions were more likely to sustain injuries requiring medical treatment (p < .01). For these women, the initial progression may have been too rapid, suggesting that musculoskeletal screening and gradual progression guided by staff is important for moderate as well as intense activity programs.

Research addressing methods to sustain long-term adherence to physical activity among older adults is needed. This study investigated the motivations and supports deemed necessary to adhere to a community-based cardiac rehabilitation (CBCR) program by individuals with established coronary heart disease.
Twenty-four long-term adherers (15 men, 9 women; age 67.7 ± 16.7 yr) took part in focus-group discussions.
Constant comparative analysis supported previous research in terms of the importance of referral procedures, social support, and knowledge of health benefits in influencing uptake and adherence to CBCR. Results also highlighted the routine of a structured class and task-, barrier-, and recovery-specific self-efficacy as necessary to sustain long-term adherence for this specific clinical group.
Older adults themselves provide rich information on how to successfully support their long-term adherence to structured exercise sessions. Further research into how to build these components into any exercise program is necessary.

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.

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.

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.
