The purpose of this study was to evaluate the effects of a 24-month moderate-intensity resistive-training intervention on strength and function in older adults. A repeated-measures experimental research design was employed as a sample of 55 apparently healthy, older, community-dwelling volunteers (30 exercisers—25 women and 5 men; 25 comparisons—16 women and 9 men) were evaluated for strength of 5 muscle groups that influence lower extremity movement and physical function. Strength and function were evaluated at 6-month intervals. The findings from this study indicate that a moderate-intensity resistive-training program increases strength in older adults and that the strength benefits are retained for the duration of the intervention. Furthermore, a long-term strength-training program can increase independent-function skills in older adults and might therefore aid in prolonging functional independence.

This study reports on a comparison of how two different groups of people with an amputation view their bodies and perceive how others view them. One group has a history of sport participation, while the other has not. The analysis is based on 14 semistructured interviews with people with amputations: 7 were engaged in sport and 7 were not. The following themes emerged: Body, Prosthesis, Independence, Human Person, and Social Barriers. One could conclude that participation in sport influences how people with an amputation perceive their body as they live with their body in a more positive way and they better accept their new body condition and their being-in-the-world. The social barriers that people with an amputation have to face daily were evident, and one of the most significant ideas was the importance of being recognized and treated as a person and not as a person with a disability.

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.

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.

The purpose of this study was to determine the relationship among health-related quality of life (HRQOL), physical fitness, and physical activity in older patients after recent discharge from hospital. One hundred fifteen independent-living older adults (ages 70–92 years) were included. HRQOL (Medical Outcomes Study 36-item Short Form Health Survey), physical activity (Physical Activity Scale for the Elderly), and physical fitness (Senior Fitness Test) were measured 2–4 weeks after discharge. Higher levels of physical activity and physical fitness were correlated with higher self-reported HRQOL. Although cause and effect cannot be determined from this study, the results suggest that a particular focus on the value of physical activity and physical fitness while in hospital and when discharged from hospital may be important to encourage patients to actively preserve independence and HRQOL. It may be especially important to target those with lower levels of physical activity, poorer physical fitness, and multiple comorbidities.

The aim was to identify barriers and opportunities facing community health physiotherapists in delivering a home-based balance exercise program to address mild balance dysfunction and, secondly, to understand the perspectives of older people in adopting this program.
Focus groups, written surveys, and data recording sheets were used with nine older people and five physiotherapists. Focus groups were audio taped, transcribed, and coded independently by two researchers.
Thematic content analysis was undertaken. Emerging themes were: engaging in preventive health (various benefits, enhancing independence); adoption of strategies (acceptable design and implementation feasibility); exercising in context (convenience, practicality, and safety); and broader implementation issues (program design, proactive health messages, and a solid evidence base).
The views of older people and physiotherapists were sought to understand the adoption of a previously successful home-based program for mild balance dysfunction. Understanding the unique context and circumstances for individuals and organizations will enhance adoption.

This article presents a case study of the developments in media gatekeeping in the last 10 years, focusing on the launch of the Tennis Channel and the ascendance of ESPN as the major network for professional tennis in the United States. The U.S. broadcast networks NBC and CBS have ceded the exclusive television rights for 2 of the Grand Slam tournaments (Wimbledon, U.S. Open) to ESPN for the first time in over 40 years. Meanwhile, the Tennis Channel, despite its independence from the media conglomerates, has carved out a niche for fans with its extensive global coverage of tournaments and for advertisers with its lucrative audience demographics. This change in dominance after the broadcast networks reigned for over 4 decades underscores the globalization of the sport and the abundance of early-round tournament matches available to fans. Organizational theories are used to analyze what has occurred and to predict what will happen next for tennis media gatekeeping in the United States.

Regular participation in resistance training is important for older people to maintain their health and independence, yet participation rates are low. The study aimed to identify motivators and barriers to older people participating in resistance training. A systematic review was conducted including quantitative, qualitative, and mixed-method studies. Searches generated 15,920 citations from six databases, with 14 studies (n = 1,937 participants) included. In total, 92 motivators and 24 barriers were identified. Motivators specific to participating in resistance training included preventing deterioration (disability), reducing risk of falls, building (toning) muscles, feeling more alert, and better concentration. Looking too muscular and thinking participation increased the risk of having a heart attack, stroke, or death, despite the minimal likelihood of these occurring, were barriers. The analysis indicates that increasing participation in resistance training among older people should focus on the specific benefits valued by older people and the dissemination of accurate information to counter misperceptions.

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.

Embedded in the self-determination theory (Deci & Ryan, 2000) framework, we obtained self-report data from 418 paid and voluntary coaches from a variety of sports and competitive levels with the aim of exploring potential antecedents of coaches’ perceived autonomy supportive and controlling behaviors. Controlling for socially desirable responses, structural equation modeling revealed that greater job security and opportunities for professional development, and lower work–life conflict were associated with psychological need satisfaction, which, in turn, was related to an adaptive process of psychological well-being and perceived autonomy support toward athletes. In contrast, higher work–life conflict and fewer opportunities for development were associated with a distinct maladaptive process of thwarted psychological needs, psychological ill-being, and perceived controlling interpersonal behavior. The results highlight how the coaching context may impact upon coaches’ psychological health and their interpersonal behavior toward athletes. Moreover, evidence is provided for the independence of adaptive and maladaptive processes within the self-determination theory paradigm.
