This cross-sectional observational study examined the frequency of older patient–physician discussions about exercise, who initiates discussions, and the quality of questioning, informing, and support about exercise. The study used a convenience sample of 396 follow-up visits at 3 community-based practice sites, with 376 community-dwelling older patients and 43 primary-care physicians. Audiotapes were analyzed using the Multi-Dimensional Interaction Analysis coding system. Results demonstrate that exercise was discussed in 13% of visits and the subject was raised equally by patients and physicians. Exercise was significantly more likely to be discussed in dyadic visits (14.7%) than in triadic visits (4.1%). Patient level of education, patient overall physical health, and the physician’s being female were significant predictors of the occurrence of exercise discussion. Given the importance of exercise for maintaining health and independence in older adults, more clinical and research attention is needed to address barriers to effective discussions in this area.

Adiposity, lean mass, and physical activity (PA) are known to influence physical function in older adults, although the independent influences are not completely characterized. Older adults (N = 156, M age = 68.9 ± 6.7 yr, 85 men) were assessed for body composition via dual-energy X-ray absorptiometry, PA by accelerometer, and physical function via timed up-and-go (UP&GO), 30-s chair stand, 6-min walk (6-min WALK), and Star-Excursion Balance Test. In the absence of percentage-body-fat by PA interactions (p > .05), main effects existed such that a higher percentage body fat was associated with poorer performance in UP&GO, 30-s chair stand, and 6-min WALK (p < .05). No significant main effects were found for PA and functional performance. Adiposity explains 4.6–11.4% in physical functional variance (p < .05). Preventing increases in adiposity with age may help older adults maintain functional independence.

Scholarship expectations of many universities in the United States are becoming more stringent. The purpose of this study was to examine variables associated with the scholarship of the sport management professoriate. The participants were 266 of the 422 academics in the NASPE-NASSM Sport Management Program List (1991). Chi-square tests of independence (alpha < .004) revealed slight tendencies for (a) younger faculty to have doctorates in areas such as sport management, psychology/sociology of sport, and legal aspects of sport rather than in physical education; (b) younger faculty to have more publications than older faculty; (c) women to be concentrated in the lower ranks and salary ranges; and (d) movement toward gender parity in rank and salary. This study should be replicated in 5 years to discover if these tendencies were precursors of trends.
The subculture of bicycle racing provides a situation in which the relationship between formal rules and dominant sport ideologies, and the taken-for-granted informal structures produced by athletes during competition, may be observed. Ethnographic and interview data suggest that such structures as pelotons and pacelines create both the opportunity for and the requirement of cooperative efforts between opponents, standing in stark contrast to more conventional conceptions of sport in which only unambiguous conflict between competitors is seen as legitimate. Here the informal norms of cooperation are central to insider definitions of the social order and are accompanied by strong sanctions for noncompliance. This cooperative informal order is seen as especially problematic for novices, as it diverges from widely held beliefs in the independence of competing units and the importance of overcoming opponents through maximum individual effort. Media coverage of the sport, in disregarding cooperative efforts, both creates and perpetuates erroneous stereotypes, making socialization into the sport more difficult.

Measurements of functional ability, balance, strength, flexibility, life satisfaction, and physical activity were compared among three populations of older adults (age 75-85 years). Sixty-nine subjects performed the Physical Performance Test (PPT). timed Up and Go. 1 repetition maximum (IRM) leg press and extensions, and Modified Sit and Reach. The Physical Activity Questionnaire for the Elderly and Satisfaction With Life Scale were also completed. No difference was found among the groups for life satisfaction. Individuals living in a nursing facility had poorer PPT scores, dynamic balance, leg extension strength, leg press strength, flexibility, and physical activity than individuals living in assisted-care facilities and the community. Assisted-care individuals had significantly lower PPT scores and leg strength than community-living individuals. The decline of ADL performance and physical activity may be accounted for by loss of strength, balance, and flexibility, all associated with a loss of independence.

In a sample of 291 adolescents (mean age 13 yr), seven psychosocial factors, including family support, were examined in relation to accelerometry-derived physical activity (PA) measured after school and during the weekend. Gender-specific stepwise linear regression analyses determined which combinations of factors explained the variance in nonschool moderate to vigorous PA and nonschool total PA after adjusting for % BF, age, and maturity (p ≤ 0.05). Being praised by a family member and % BF explained 13% of the variance in female nonschool MVPA, while being praised and maturity explained 13% of the variance in nonschool total PA. Having a family member watch him participate, % BF, and age explained 11.5% of the variance in male nonschool MVPA, while having a family member participate with him explained 6.4% of the variance in nonschool total PA. Despite adolescents’ growing independence, family support continues to influence PA levels.

Two reasons given for the dramatic decline in the percentage of women coaches since the passage of Title IX have been the effectiveness of the “good old boys” network and the lack or ineffectiveness of the “good old girls” network. With homologous reproduction used as a theoretical basis for these networks, 1,106 public secondary schools were surveyed to determine their administrative structures based on the sex of the principals and the athletic directors. Two types of administrative structures were identified with four models under each type. The numbers of male and female head coaches in the girls' athletics program under each administrative structure were determined and analyzed for independence. Significant differences were found between the different administrative models and the gender of the head coaches. Findings are discussed in terms of the prevailing administrative structures and the representation of females in coaching as a result of the dominant group reproducing itself.

Aging leads to a decline in strength and an associated loss of independence. The authors examined changes in muscle volume, maximum isometric joint moment, functional strength, and 1-repetition maximum (1RM) after resistance training (RT) in the upper extremity of older adults. They evaluated isometric joint moment and muscle volume as predictors of functional strength. Sixteen healthy older adults (average age 75 ± 4.3 yr) were randomized to a 6-wk upper extremity RT program or control group. The RT group increased 1RM significantly (p < .01 for all exercises). Compared with controls, randomization to RT led to greater functional pulling strength (p = .003), isometric shoulder-adduction moment (p = .041), elbow-flexor volume (p = .017), and shoulder-adductor volume (p = .009). Shoulder-muscle volumes and isometric moments were good predictors of functional strength. The authors conclude that shoulder strength is an important factor for performing functional reaching and pulling tasks and a key target for upper extremity RT interventions.

Physical activity is important for maintaining independence and quality of life in older people living in care homes. Little is known about patterns of physical activity or sedentary behavior in this population.
Thirty-three care home residents (82.6 ± 9.2 years) wore an ActiGraph GTX3 accelerometer for seven days, which provided minutes of sedentary behavior and low, light, and moderate-to-vigorous physical activity. Participants undertook the Mini-Mental State Examination and care staff reported activities of daily living (Barthel index) and functional ambulation classification (FAC) for each participant.
Participants spent on average 79% of their day sedentary, 14% in low, 6% in light, and 1% in moderate-to-vigorous physical activity. Activity levels did not significantly differ between days or hours of the day (P > .05).
Levels of physical activity were very low and time being sedentary was high. This study can inform physical activity and sedentary behavior interventions for care homes’ residents.

The aging process leads to adverse changes in body composition (increases in fat mass and decreases in skeletal muscle mass), declines in physical function (PF), and ultimately increased risk for disability and loss of independence. Specific components of body composition or muscle capacity (strength and power) may be useful in predicting PF; however, findings have been mixed regarding the most salient predictor of PF. The development of a conceptual model potentially aids in understanding the interrelated factors contributing to PF with the factors of interest being physical activity, body composition, and muscle capacity. This article also highlights sex differences in these domains. Finally, factors known to affect PF, such as sleep, depression, fatigue, and self-efficacy, are discussed. Development of a comprehensive conceptual model is needed to better characterize the most salient factors contributing to PF and to subsequently inform the development of interventions to reduce physical disability in older adults.
