The U.S. Department of Health and Human Services (1990) has specified as a key objective the reduction of disability in the performance of activities of daily living (ADL) for persons over the age of 65 years. Many ADL involve combinations of muscular strength, muscular endurance, and flexibility, three components that together have been referred to as "muscular fitness." The capacity of the elderly to remain functionally independent, therefore, may depend less on cardiovascular fitness, which has traditionally been the focus of health related fitness research, than on these components of muscular fitness. This review addresses the issue of muscular fitness and disability in the elderly by considering three questions: Is muscular fitness associated with ADL performance? Can muscular fitness be improved with exercise training? Do improvements in muscular fitness improve ADL performance? Answers to these questions will have important implications for future research and program implementation. Although initial findings are promising, more data are needed on the effect of muscular fitness on functional independence and quality of life in the elderly.

The purpose of this study was to examine patterns of physical activity (PA) during a single weekend to ascertain possible relationships between PA and anthropometry, fundamental motor skills, and CHD risk factors among 105 normal male and female children, aged 3–4 years. The children played, when awake, on the average for 14 hr, 16 min indoors and for 5 hr, 12 min outdoors of which low activity playing accounted about 4 hr. Notable gender differences were observed in the intensity of PA but not in fundamental motor skills and CHD risk factors. The results suggest that physical activity is weakly related to fundamental motor skills and CHD risk factors at an early age. The association between PA and body size was modified by gender (p = .024): The girls who played indoors a lot were heavier than the others, and the boys who played much more outdoors were heavier in relation to other boys. The associations between PA and motor skills as well as PA and CHD risk factors were also highly gender-dependent: The boys benefited from interacting with parents, while the girls benefited from independence. The most influential factors seemed to be the amount of playing outdoors, the amount of high level play activities, as well as interaction with parents.

This study represents a first step in the development and validation of a measure of sport-specific self-acceptance. Phase 1 of this study involved instrument design and pilot testing. In Phase 2 a random sample of Division I collegiate athletes (N=131) were asked to complete the Self-Acceptance Scale for Athletes (SASA) as well as measures of general self-acceptance self-esteem, stability of self-concept, and sport-specific self-description (i.e., perceived competence/adequacy). Test-retest coefficients ranged from 62 to .75 and alpha coefficients ranged from .58 to .80. Factor analysis suggests two factors, independence of self-regard and self-accepting self-regard representing the two dimensions of self-acceptance measured in the SASA. Scores on the SASA have moderate correlations with general self-acceptance, self-esteem, and stability of self-concept. A significantly stronger relationship between self-esteem and perceived competence/adequacy than between self-acceptance and perceived competence/adequacy suggests that the SASA is able to discriminate between these closely related constructs

The goal of this study was to identify the relationships between the learning choices made by pupils and their personal characteristics, including cognitive style (field dependence–independence), a motivational variable (feeling of self-efficacy), and a cognitive variable (task representation). The participants were 64 twelve-year-old sixth graders from a suburban middle school in France (35 boys and 29 girls). Cognitive style or FDI was measured with the Group Embedded Figures Test, a perceptual test that requires finding a simple geometrical figure embedded in a complex geometrical one. Five learning conditions (autonomy, tutoring, verbal instruction, silent demonstration, and verbal demonstration) were then proposed in random order to the pupils. They were asked to select a learning method to solve a motor problem: a badminton service. The results indicated an absence of relationships between the choice of a learning condition and cognitive style. Three variables partially predicted the learning-condition choice: feeling of self-efficacy, task representation, and motor performance. The present results can be interpreted in the light of studies on children’s help-seeking behavior in problem-solving situations.

Physical inactivity is associated with increased morbidity and mortality. This study provides prevalence estimates of inactivity by select characteristics among older adults.
Respondents ≥50 years of age were selected from the 2005 Behavioral Risk Factor Surveillance System (N = 185,702).
Overall, 30.0% of older adults did not engage in leisure-time physical activity. Within each racial/ethnic group, the prevalence of inactivity was highest among Hispanic men (41.9%) and women (42.4%). Among men with and without disabilities, chronic disease conditions associated with inactivity were angina or coronary artery disease. Among women with disabilities, chronic disease conditions associated with inactivity were stroke and diabetes; among women without disabilities only diabetes was significantly associated with inactivity.
Regular physical activity is an important means to maintaining independence, because it substantially reduces the risk for developing many diseases; contributes to healthy bones, muscles, and joints; and can reduce the risk for falling. Health care providers are encouraged to discuss concerns regarding physical activity with their patients.

Understanding factors that influence live game-day attendance has garnered significant attention from both researchers and practitioners in the sport industry. Despite the National Football League’s unprecedented annual revenues, league attendance remains down, spurring large-scale investment into the game-day experience (Florio, 2008). In this case, students will perform various statistical analyses (i.e., computing chi-square tests of independence, t tests, effect sizes [Cohen’s d], and confidence intervals) to determine which factors most strongly influence fan attendance at Jacksonville Jaguars home games. Specifically, this case investigates the degree to which stadium upgrades motivate fans to attend and explores the extent to which fans support the use of public funds for stadium upgrades. Answering these questions will further equip future sport managers to make data-driven decisions regarding the utility of strategies—such as stadium projects—to enhance the game-day experience. Furthermore, students can use the knowledge gained from the case to critically analyze public investment in sport stadia as well as the ways in which consumers’ preferences are either independent of or depend on categorical variables such as gender. The case is intended for use in research methods courses and is also applicable to sport marketing, sport facility, and sport finance courses.

To question the relation between uni- and bipedal postural skills, 21 subjects were required to stand on a force platform through uni- and bipedal conditions. These two protocols are commonly used paradigms to assess the balance capacities of healthy and disabled patients. The recorded displacements of the center of pressure (CP) were decomposed along mediolateral and anteroposterior axes and assessed through variance positions and parameters obtained from fractional Brownian motion (fBm) modeling to determine the nature and the spatiotemporal organization of the successive controlling mechanisms. The variances underline the relative independence of the two tasks. Nevertheless, as highlighted by the fBm framework, postural correction is initiated for the unipedal stance after shorter time delays and longer covered distances. When compared to bipedal standing, one of the main characteristics of unipedal standing is to induce better-controlled CP trajectories, as deduced from the scaling regimes computed from the fBm modeling. Lastly, the control of the CP trajectories during the shortest time intervals along the anteroposterior axis appears identical for both uni- and bipedal conditions. Unipedal and bipedal standing controls should thus be viewed as two complementary tasks, each providing specific and complementary insights into the postural control organization.
This study examines the historical significance of Jang Gwon’s activities in the sport promotion carried out by Korea’s YMCA. At its birth, the Korean YMCA’s sport promotion was closely linked with the Korean nationalist movement under Japanese colonial rule, and this link was most evident around 1920, when Jang Gwon worked as a judo master. Citing the Sokol movement in Czechoslovakia, Jang Gwon took initiatives to enlighten Korean people’s consciousness and popularize sports, including judo and basketball, across the country through the Korean YMCA’s sport promotion. In particular, Jang Gwon introduced modern judo—formally known as Gangdogwan (Kodokan judo), initiated by Jigoro Kano—in Korea and took initiatives to establish the Korean Basketball Association and the Korean Basketball Referee Association. Through the Korean YMCA’s sport promotion, Jang Gwon motivated the Korean people to aspire to liberation and independence from Japanese colonial rule. Moreover, amid the prevailing social climate, in which physical activities were discouraged due to the influence of Neo-Confucianism, he provided a paradigm shift that called for “sport for all,” which enabled the modernization of sports and physical education in Korea.

For more than half a century fellows of the National Academy of Kinesiology have enthusiastically advocated for the promotion and adoption of physically active lifestyles as an affordable and effective means to prevent chronic diseases and conditions, and enhance independence and high quality of life for older adults. It is possible to discern distinct evolutionary stages when examining scholarship related to the role of physical activity in the promotion of healthy aging. Research into physical activity and aging began with critical early studies that established the underlying scientific evidence for a relationship between physical activity and healthy aging. More recent work has addressed such topics as building consumer demand, developing policies and legislation to support active aging, and understanding the complex interrelationships between physical activity and other lifestyle factors in the prevention and treatment of chronic diseases and conditions. It is increasingly apparent that strategies to promote active and successful aging must be integrated into an effective public policy. Kinesiologists and other health professionals, working in collaboration with colleagues from other disciplines, can help to reduce risk factors for chronic disease and improve quality of life for older adults by building awareness of the importance of physical activity and by assisting with the development and implementation of appropriate and effective interventions that reduce risk factors and improve quality of life.

This cross-sectional study was performed to examine associations of objectively measured sedentary time (ST) and breaks in sedentary time (BST) with instrumental activities of daily living (IADL) disability in Japanese community-dwelling older adults.
The sample comprised 1634 older adults (mean age: 73.3 y, men: 38.4%). Sedentary behavior was measured using a triaxial accelerometer. Disability was defined as inability in at least 1 of the IADL tasks using the Tokyo Metropolitan Institute of Gerontology Index of Competence.
After adjusting for potential confounders and moderate-to-vigorous physical activity (MVPA), longer ST was significantly associated with higher likelihood of IADL disability, whereas a greater number of BST was associated with lower likelihood of IADL disability. ST and BST remained statistically significant after mutual adjustment with odds ratio of 1.30 (95% confidence interval [CI)], 1.00–1.70) and 0.80 (95% CI, 0.65–0.99), respectively.
This study first demonstrated that shorter ST and more BST were associated with lower risk of IADL disability independent of MVPA and that the association for ST was independent of BST and vice versa. These findings suggest not only total ST but also the manner in which it is accumulated may contribute to the maintenance of functional independence in older adults.
