It is proposed that the focus of sport management research be broadened to include those individuals who fill management positions in sport/fitness-related enterprises. A particularly useful approach is that of organizational behavior as it pertains to sport/fitness managers. Drawing from the content of organizational behavior for use in the study presented here, items of measure for job satisfaction include ability utilization, achievement, activity, advancement, authority, company policies/practices, compensation, co-workers, creativity, independence, moral values, recognition, responsibility, security, social service, social status, supervision-human relations, supervision-technical, variety, and working conditions. The corporate fitness managers participating in this study reported their level of general job satisfaction to be an average of 78.67 out of a possible 100 points. The factors shown to be significantly more satisfying than all other factors at the .05 level were social service and moral values. Additionally, although not significantly different from each other, both factors of advancement and compensation were revealed to be significantly more dissatisfying at the .05 level than all other factors.

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.

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.

Background:

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.

Methods:

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.

Results:

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.

Conclusions:

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.

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.

Cognitive-Affective Stress Management Training (SMT) is a coping skills training program designed to help athletes control dysfunctional stress processes (Smith, 1980). The present quasi-experimental study investigated the effects of SMT on affect, cognition, and performance in high performance youth volleyball players. Members of Alberta's Canada Games men's and women's (under 19 years of age) volleyball teams were assigned to either an experimental treatment group or a waiting-list control group. The treatment program consisted of eight modules, approximately 1 week apart, that allowed subjects to learn and apply somatic and cognitive coping skills. The results indicated that the treatment group emitted fewer negative thoughts in response to videotaped stressors and had superior service reception performance in a controlled practice compared to the control group. There were no interpretable differences between groups for either state anxiety (CSAI-2) or trait anxiety (SCAT). The cognitive and performance measures provided converging support for Smith's program. The results are discussed in terms of coping skills training, theoretical issues regarding the measurement of anxiety, and possible affect-cognition system independence.

The relationship of objectively measured sedentary time (ST), frequency of breaks in ST, and lower extremity function (LEF) was investigated in a diverse sample aged ≥ 70 years (n = 217). Physical activity (PA) was assessed by accelerometry deriving moderate-vigorous PA (MVPA) minutes per registered hour (MVPA min · hr−1), registered ST (ST min · hr−1), and breaks in ST min · hr−1 (breaks · hr−1). LEF was assessed by the Short Physical Performance Battery. Univariate associations with overall LEF were MVPA (r = .523), ST (r = −.499), and breaks (r = .389). Adjusted linear regression including MVPA min · hr−1, ST min · hr−1, and breaks · hr−1 explained 41.5% of LEF variance. Each additional break · hr−1 was associated with 0.58 point increase in LEF. Breaks and MVPA had strongest independent associations with LEF. Promoting regular breaks might be useful in maintaining or increasing LEF and later life independence. This novel finding is important for the design of effective lifestyle interventions targeting older adults.

Sport teams historically have been reluctant to change ticket prices during the season. Recently, however, numerous sport organizations have implemented variable ticket pricing in an effort to maximize revenues. In Major League Baseball variable pricing results in ticket price increases or decreases depending on factors such as quality of the opponent, day of the week, month of the year, and for special events such as opening day, Memorial Day, and Independence Day. Using censored regression and elasticity analysis, this article demonstrates that variable pricing would have yielded approximately $590,000 per year in additional ticket revenue for each major league team in 1996, ceteris paribus. Accounting for capacity constraints, this amounts to only about a 2.8% increase above what occurs when prices are not varied. For the 1996 season, the largest revenue gain would have been the Cleveland Indians, who would have generated an extra $1.4 million in revenue. The largest percentage revenue gain would have been the San Francisco Giants. The Giants would have seen an estimated 6.7% increase in revenue had they used optimal variable pricing.

Clinical Scenario:

Even though chronological aging is an inevitable phenomenological consequence occurring in every living organism, it is biological aging that may be the most significant factor challenging our quality of life. Development of functional limitations, resulting from improper maintenance and restoration of various organ systems, ultimately leads to reduced health and independence. Skeletal muscle is an organ system that, when challenged, is often injured in response to varying stimuli. Overt muscle-strain injury can be traumatic, clinically diagnosable, properly managed, and a remarkably common event, yet our contemporary understanding of how age and environmental stressors affect the initial and subsequent induction of injury and how the biological processes resulting from this event are modifiable and, eventually, lead to functional restoration and healing of skeletal muscle and adjacent tissues is presently unclear. Even though the secondary injury response to and recovery from "contraction-induced" skeletal-muscle injury are impaired with aging, there is no scientific consensus as to the exact mechanism responsible for this event. Given the multitude of investigative approaches, particular consideration given to the appropriateness of the muscle-injury model, or research paradigm, is critical so that outcomes may be physiologically relevant and translational. In this case, methods implementing stretch-shortening contractions, the most common form of muscle movements used by all mammals during physical movement, work, and activity, are highlighted.

Clinical Relevance:

Understanding the fundamental evidence regarding how aging influences the responsivity of skeletal muscle to strain injury is vital for informing how clinicians approach and implement preventive strategies, as well as therapeutic interventions. From a practical perspective, maintaining or improving the overall health and tissue quality of skeletal muscle as one ages will positively affect skeletal muscle’s safety threshold and responsivity, which may reduce incidence of injury, improve recovery time, and lessen overall fiscal burdens.

We previously reported that lower extremity muscular strength of older adults did not predict success of a balance recovery task. We propose that lower extremity coordination may limit performance independently of lower extremity strength. The present study was conducted to determine the extent to which knee extension strength and hip–knee coordination independently contribute to maximum vertical jump height. Maximum vertical jump height and isometric and isokinetic knee extension strength and power were determined in 13 young adults. Hip–knee coordination during the vertical jump was quantified using relative phase angles. Stepwise nonlinear multiple regression determined the variable set that best modeled the relationship between the dependent variable, maximum vertical jump height, and the independent variables of strength, power, and coordination. The quadratic terms of the normalized knee extension strength at 60 deg·s–1, and the average relative phase during the propulsion phase of the vertical jump, collectively accounted for more than 80% of the shared variance (p = .001). The standardized regression coefficients of the two terms, .59 and .52, respectively (p = .004 and .008), indicated the independence and significance of the contributions of knee extension strength and hip–knee coordination to maximum vertical jump height. Despite the pitfalls of extrapolating these results to older adults performing a balance recovery task, the results are interpreted as supporting the contention that while muscle strength confers a number of functional benefits, the ability to avoid falling as a result of a trip is not necessarily ensured. Increased muscle strength per se can occur in the absence of improved kinematic coordination.
