We examined whether the momentary induction of state mindfulness benefited subsequent balance performance, taking into consideration the effects of dispositional mindfulness. We also tested whether our mindfulness induction, grounded in sustaining moment-to-moment attention, influenced the attentional focus strategies that were adopted by the participants during the balancing task. Balance performance was ascertained based on approximate entropy (ApEn) of the center of pressure (COP) data. The study involved 32 males (age: M = 22.8, SD = 1.94) who were randomly assigned to the mindfulness or control group. Using difference in pretest to posttest performance based on the medio-lateral movements as the dependent variable, the test for interaction showed that the mindfulness induction was more effective for participants with higher dispositional mindfulness. Participants who underwent mindfulness induction also reported greater use of external focus strategies than those in the control group. Results suggest that momentary mindful attention could benefit balance performance and affect the use of attentional focus strategies during movement control.

Increasing evidence underscores the health benefits of Tai Chi (TC), although there is limited evidence of benefits among racial and ethnic minorities. This study investigated the impact of psychosocial status on balance among 23 Latino seniors after a twice-a-week, 12-week TC exercise program. Functional status was measured at baseline, immediately after, and three months following the TC exercise program, using the Timed Up and Go Test and Tinetti Falls Efficacy Scale. Psychosocial status was measured at baseline by the Center for Epidemiologic Studies Depression Scale and Norbeck Social Support Questionnaire. Both measures of functional status improved and were sustained after three months of TC. Greater improvement was significantly related to a higher level of baseline social support. More depressed seniors reported less fear of falling after TC. Depression and social support are important moderators of functional improvement after TC among Latino seniors.

A comprehensive measure of activity-related support was developed and used to examine gender differences in activity support and links between support and physical activity in a sample of adolescents.
Participants included 202 middle school girls and boys. Participants completed the Activity Support Scale and three self-report measures of physical activity.
Seven sources of support were identified including maternal and paternal logistic support, maternal and paternal modelling, general familial support, sibling support, and peer support; all scales were internally consistent. No gender differences in activity-related support were identified. Adolescents who were more active reported higher levels of activity support from all sources except maternal and paternal modelling of physical activity.
Results from this study highlight the importance of activity-related support from family and friends as a potential method to promote and sustain physical activity among adolescents.

The purpose of this paper is to discuss the shared interest of the public health and parks and recreation sectors in promoting active visits to parks. At the institutional level, both sectors have missions to promote physical activity and view parks as key components in attaining physical activity goals. While some balancing among park goals may be necessary to avoid overuse and resource degradation, active visits more often complement park sustainability goals by reducing automobile and other motorized use impacts. The public health and parks and recreation sectors have each developed ecologic models to understand the determinants and outcomes of park-related physical activity. Transdisciplinary integration of these modeling efforts can lead to a better understanding of how active visits fit within the context of the overall recreational experience and the full range of benefits that parks provide. We conclude by identifying strategies for improving collaboration between the public health and parks and recreation sectors.

This study examined the relationship between the three facets of subjective meaning—personal incentives, sense of self, and perceived behavioral options—and adherence behaviors in the athletic injury rehabilitation setting. Subjects were 40 intercollegiate athletes who had sustained a sport related injury; all completed a questionnaire assessing the three components of meaning specific to sport and injury rehabilitation. Adherence was defined as a composite of attendance at the prescribed sessions, degree of completion of the prescribed exercise protocol, and the athlete's intensity or effort exerted in performing the prescribed exercise. Multiple-regression analyses indicated that each dimension significantly predicted adherence behaviors. Athletes who demonstrated greater adherence believed in the efficacy of the treatment, perceived more social support for their rehabilitation, were more goal directed or self-motivated, and placed more emphasis on mastery or task-involved goals in sport.

To identify and characterize the scientific literature on the effects of exercise on Alzheimer’s disease, research was conducted in the following databases: MEDLINE, CINAHL, Web of Science, and Scopus. These MeSH terms—“exercise”, “motor activity”, “physical fitness”, “Alzheimer disease”, and its synonyms in English—were used in the initial search to locate studies published between 2003 and 2013. After reading the 12 final articles in their entirety, two additional articles, found by a manual search, were included. Of these, 13 had beneficial results of exercise in Alzheimer’s disease. Given the results discussed here, the exercise may be important for the improvement of functionality and performance of daily life activities, neuropsychiatric disturbances, cardiovascular and cardiorespiratory fitness, functional capacity components (flexibility, agility, balance, strength), and improvements in some cognitive components such as sustained attention, visual memory, and frontal cognitive function in patients with AD.

The term “community-based” can refer to many types of physical activity interventions. The bulk of physical activity research in older adults focuses on changing individual behavior, sometimes in community settings. Addressing the nation’s goal of increasing the proportion of physically active older adults requires more programs to improve contextual factors that support individual behavior and calls for introducing into community settings successful individual-level programs based on solid research. The social ecology model provides an ideal multilevel framework for community-wide efforts. In conjunction with programs to increase the types and levels of physical activity of older adults, changes can be directed at social, cultural, environmental, institutional, and policy contexts for individual behavior change. Guidelines and evaluation methods, including cost analysis of developing, implementing, and sustaining programs, are needed. Recommendations are made to advance community-based strategies for promoting physical activity among adults age 50 and older.

Based on the contention that leadership has sustained effects on followers even after the leader–follower relationship has ended, we investigated the career-long effects of abusive coach leadership on athlete aggression and task performance. Abusive leadership scores were derived from ratings by two independent raters’ evaluations of coaches’ biographies, and athlete aggression and task performance data were derived from objective sources. Data were obtained from players (N = 693) and coaches (N = 57) involved in the National Basketball Association (NBA) between the 2000–2001 and 2005–2006 seasons. Controlling for tenure, salary, team winning percentage, and absence due to injuries, multilevel modeling showed that exposure to abusive leadership influenced both the trajectory of psychological aggression and task performance over players’ careers. These findings suggest that the effects of abusive leadership extend far longer than currently acknowledged, thus furthering our understanding of the nature and effects of abusive leadership.

Resistance training (RT) increases strength in older adults, but there have been few studies of long-term RT or detraining in older adults. Postmenopausal participants (51–71 years of age) were randomized to RT or a control group for Year 1. For Year 2, participants chose whether to resistance train or not. Three groups emerged: train/train (n = 8: 60 ± 4 years), train/no train (n = 11: 62 ± 3 years), or controls (n = 17; 58 ± 6 years). Both training groups increased strength (p < .05) in Year 1. In Year 2, train/train maintained strength, whereas train/no train lost strength for knee extension (p < .001) but not for arm pulldown. Controls did not change. Reported physical activity levels were significantly increased in trainers in Year 1 and remained high regardless of RT in Year 2 (p < .05). Therefore, sustained changes in strength and physical activity behavior might be possible even if RT is discontinued.

To describe the effectiveness of a multi-strategy physical activity (PA) intervention.
Self-report data from random samples were collected prior to and following intervention. Social marketing, healthcare provider, and environmental strategies were concurrently implemented with a central coordinating theme of “10,000 Steps Rockhampton.”
There was evidence of significant project reach and awareness. The downward trend in PA seen in the comparison community (48.3% to 41.9% “active”) was not evident in Rockhampton. Women were the “early adopters” in this project; with an increase of 5% (95% CI: –0.6, 10.6) in the percent categorized as “active” (compared with decreases among women in the comparison community and among men in both communities).
High levels of project awareness, combined with modest increases in activity levels in women, demonstrate initial project effects. Longer term interventions, focusing on sustainable individual, social, and environmental change strategies are needed to maintain and improve this result.
