Correlates of physical activity participation in community-dwelling older adults

The authors examined factors related to participation in walking, gardening or yard work, and sports or exercise in 686 community-dwelling adults 60-95 years of age from Wave IV of the population-based Americans' Changing Lives Study. Logistic regression revealed that male gender, being married, and better functional health were associated with greater likelihood of participating in gardening or yard work (p < .05). Male gender, better functional health, and lower body-mass index were independently associated with greater likelihood of walking (p < .05). Increasing age, male gender, higher education, and better functional health were associated with greater likelihood of participating in sports or exercise (p < .05). Subsequent analyses yielded an interaction of functional health by gender in sport or exercise participation (p = .06), suggesting a greater association between functional health and participation in men. Gender and functional health appear to be particularly important for physical activity participation, which may be useful in guiding future research. Attention to different subgroups may be needed to promote participation in specific activities.     

Academic incentives for students can increase participation in and effectiveness of a physical activity program

The authors sought to determine whether a greater academic incentive would improve the effectiveness and student adherence to a 12-week voluntary exercise program designed to decrease students' percentage of body fat. They randomly assigned 210 students to 1 of 2 groups with different academic reward structures. The group with the greater reward structure showed better exercise adherence and lost more body fat than those without the additional incentive. These findings suggest that an academic incentive can increase overall student adherence to a voluntary exercise program and can boost the effectiveness of the program in a university environment. The findings also have potential implications for on-campus promotion of physical activity.     

College students' motivation for physical activity: differentiating men's and women's motives for sport participation and exercise

Despite the many clear benefits of an active lifestyle, lack of physical activity is a significant health problem in the college population. A key issue in physical activity research is developing an understanding of motivation. Although physical activity takes many forms, most research designed to enhance motivation for and adherence to physical activity focuses on exercise behavior and ignores sport participation. In this study, the authors compare motivations for sport participation versus exercise among college students. Results indicate that participants were more likely to report intrinsic motives, such as enjoyment and challenge, for engaging in sport, whereas motivations for exercise were more extrinsic and focused on appearance and weight and stress management. The findings suggest that motives for sport participation are more desirable than those for exercise and may facilitate improved adherence to physical activity recommendations.     

Alcohol use and participation in organized recreational sports among university undergraduates

OBJECTIVE: The authors examined alcohol use among students involved in recreational sports. To the authors' knowledge, this is the first study of alcohol use in which researchers separate recreational sports participants from intercollegiate athletes and examine them as a separate group of interest. PARTICIPANTS: The authors generated a random sample of 494 students from the undergraduate population at a 4-year university. METHODS: They used a Web-based survey to collect data and stratified and weighted the sample by residence status to more accurately reflect the population. RESULTS: Students who participated in recreational sports used alcohol at a greater frequency and intensity than did those who were not involved in recreational sports across a variety of measures, even alongside other variables, including race, sex, and Greek membership. CONCLUSIONS: On the basis of these findings, alcohol consumption among those participating in recreational sports appears to be an area worthy of consideration in future research.     

Neighborhood influences on physical activity in middle-aged and older adults: a multilevel perspective

Over the past few years, attention has been drawn to the importance of neighborhood influences on physical activity behavior and the need to consider a multilevel analysis involving not only individual-level variables but also social- and physical-environment variables at the neighborhood level in explaining individual differences in physical activity outcomes. This new paradigm raises a series of issues concerning systems of influence observed at different hierarchical levels (e.g., individuals, neighborhoods) and variables that can be defined at each level. This article reviews research literature and discusses substantive, operational, and statistical issues in studies involving multilevel influences on middle-aged and older adults' physical activity. To encourage multilevel research, the authors propose a model that focuses attention on multiple levels of influence and the interaction among variables characterizing individuals, among variables characterizing neighborhoods, and across both levels. They conclude that a multilevel perspective is needed to increase understanding of the multiple influences on physical activity.     

Benefits and barriers to sports participation for athletes with disabilities: the case of Malaysia

The purpose of this paper was to explore the benefits and barriers influencing participation for athletes with disabilities from a developing country (Malaysia). Two independent studies were undertaken: Study 1 included a sample of 123 athletes (95 males, 28 females) who participated in the 2006 Far East and South Pacific Games for the Disabled (FESPIC Games); Study 2 involved focus group discussions with 14 elite athletes. The athletes ranged in age from 15 to 59?years. Data were collected through a questionnaire (Study 1) and focus group discussions (Study 2). The primary reasons for participation in sport were achievement/challenge (58%) and competency/skill development (41%). The main barriers faced by the athletes were structural (facilities, equipment, funding) and the negative attitude from the government, public and media. However, despite these difficulties the majority of athletes were keen to continue to compete. Further work is required to ensure athletes with disabilities are provided with similar opportunities to athletes without disabilities.     

Aging and well-being in French older adults regularly practicing physical activity: a self-determination perspective

The purpose of this study was to identify the motivational profiles of physically active older adults and to achieve a better understanding of their perceived motives to explain their regular physical activity behavior in relation to self-determination theory (SDT). To address these aims, this study used quantitative and qualitative approaches. Older adults (n = 92; M = 74.95, SD = 4.6) completed the French version of the Sport Motivational Scale. A cluster analysis showed two motivational profiles with differential motivational patterns. The first was named the high combined profile, with high scores on intrinsic motivation and introjected regulation and low levels of external regulation. The second profile was the low to moderate motivational profile, with low scores on intrinsic motivation and moderate scores on introjected regulation. The qualitative study's results demonstrate the usefulness of SDT in explaining the relationship between these motivational profiles and the intertwining of the three basic psychological needs.     

Brown,Title IX and the impact of race and sex segregation on sports participation opportunities for Black females

Although neither the 1954 Brown v. Board of Education of Topeka, Kansas decision nor Title IX of the Education Amendments Act (1972) specifically mentions sports participation, both antidiscrimination laws have changed the landscape of high school and college sports by granting Blacks and females increased access to athletic opportunities previously reserved for Whites males. Although Brown and Title IX are popular topics among research scholars, studies rarely consider the unique experiences of Black females, who unlike Black males and White females, occupy at least two subordinate social locations due to their race and gender. This article goes beyond the usual single axis of inquiry and examines the intersection of Brown and Title IX and, thus, the intersection of race and sex for Black females who inhabit a sports world dominated by Whites and males. Using existing literature to assess the implementation and effectiveness of Brown and Title IX independently before exploring their sociohistorical linkages and integrated effect on access to sports participation opportunities, the author finds that Black women and girls have been left out of the game.     

Farm-level constraints on agri-environmental scheme participation: a transactional perspective

Voluntary agri-environmental schemes based on management agreements characterise much agri-environmental policy across the EU at present, and have expanded following the implementation of Regulation 2078/92 in all member states. Schemes generally motivate individual farmers to contract with government agencies to produce countryside goods in return for compensatory payments. Hence, farmers’ decisions to participate are central to achieving policy objectives. An enhanced understanding of farmers’ attitudes to and perceptions of schemes and their implementation would be of value for policy development. Recent transactions-cost research has observed that such schemes involve potentially heavy transactions costs, for both the state and farmers. In addition to reducing scheme cost-effectiveness, the transactions costs incurred by farmers can form a significant constraint on participation in schemes, with adverse effects on the supply of conservation goods. This paper considers behavioural and transactional perspectives on scheme participation. Some new data on the transactional burdens experienced by farmers when participating in schemes is examined from the perspective of identifying ways to improve policy transacting to ease constraints on participation where these exist. At the level of the individual participant, the development of agri-environmental one-stop-shops in member states for all schemes would allow transactions-cost economies, saving on the overhead costs of applying to different schemes with different objectives, as well as allowing a more integrated, less confused approach to participation. The longer-term value of farmer networks and capacity-building for agri-environmental management is important too.     

Factors related to meeting physical activity guidelines in active college students: A social cognitive perspective

Objective: To examine the relations of sex, exercise self-efficacy, outcome expectations, and social support with meeting physical activity guidelines (PAGs). Participants: Three hundred ninety-six college students participated in this study in the summer 2013. Methods: Students completed online questionnaires that assessed physical activity behaviors and psychosocial factors (ie, self-efficacy, outcome expectancies, and social support). Students' physical activity profile was categorized as meeting no PAGs, meeting aerobic PAGs only, meeting muscle-strengthening PAGs only, or meeting both PAGs. Results: A multinomial logistic regression revealed that students' sex and psychosocial factors significantly affected the odds of meeting any and all PAGs. Sex significantly moderated the relationship between outcome expectancy and meeting aerobic PAGs and between outcome expectancy meeting muscle-strengthening PAGs. Conclusions: Results indicate that interventions designed to increase psychosocial factors may increase the likelihood of students meeting any and all PAGs. Social support may be especially beneficial for increasing muscle-strengthening activity.     

Diabetes, aging and physical activity

Diabetes mellitus (DM) is a metabolic disease affecting the regulation of insulin and glucose causing a disruption in the normal control of counterregulatory hormones and macronutrients, resulting in blood glucose accumulation. Metabolic deregulation leads to the production of noxious substances that have a particular propensity for damaging vascular and nervous structures. Physiological changes observed with aging are correlated with a concomitant increase in DM and its associated complications. Long-term complications, including peripheral and central neuropathies, micro- and macrovascular damage, retinopathy, and nephropathy are the major causes of mortality in diabetics [cardiovascular disease (CVD) being the primary complication causing death in this population]. All-cause mortality is three to four times greater in the DM population; hence, management of DM is of timely importance, particularly with a projected prevalence increase of 134% within the next 25 years among individuals over the age of 65 years. Exercise modalities, including endurance and resistance training, were employed to improve glycemic/metabolic control and to ameliorate the progression of DM-related complications. Several risk factors, including glucose levels, blood pressure, lipid/cholesterol profile, and BMI, are reportedly improved with these modes of exercise. However, not all studies demonstrate an improvement in risk factors, but consistently note improvement in complications and a reduction of DM incidence. There is convincing evidence that exercise, with or without specific improvements to traditional DM-related risk factors, is an effective therapy for the management of DM.The Canadian Centre for Activity and Aging is affiliated with St. Joseph’s Health Care and The University of Western Ontario, London, Ontario, Canada.     

Fertility, labor force participation, and tastes: An economic psychology perspective

Economic and economic psychology models of wife's labor force participation and family size decisions are examined within the context of a marriage cohort. Among other results, it was found that tastes influence the demand for work and number of children, along with traditional economic determinants such as opportunity costs and income. Tastes have an especially strong impact when modeled as unobservables, in order to correct for measurement error. Further, the often observed empirical association between labor force participation and fertility is found to be spurious and not necessarily causal in nature. That is, labor force participation and fertility negatively covary largely as a consequence of common economic and taste antecedents and not due to reciprocal interactions. Hypotheses were tested using a new structural equation methodology.     

Operationalizing environmental indicators for physical activity in older adults

This qualitative study describes environmental supports and barriers to physical activity in an older adult sample drawn from low- and high-walkable neighborhoods. Thirty-seven individuals age 55 and over were recruited and answered open-ended survey questions, with a subsample invited back to partake in a semistructured interview. Content analysis identified categories and themes linking perceptions of neighborhood-environment characteristics to activity. Emerging categories and themes did not differ across neighborhood walkability, so results are presented for both groups combined. Infrastructure was the most common category identified to encourage activity, specifically, well-maintained sidewalks, bike paths or lanes, and traffic control. Other categories of land use, landscape, and aesthetics were reported. Poorly maintained or missing sidewalks, crosswalks, bike paths or lanes, and traffic safety were categories that discouraged activity. In conclusion, the information obtained is helpful in solidifying which environmental characteristics are important to measure as they relate to activity behavior in an older adult population.     

Getting tougher for the fourth quarter: boomers and physical activity

Baby Boomers might not consider themselves as growing old but are starting to reach the last quarter of average life spans. This article asks how Boomers prepare for their fourth quarters through physical activity. Three years (1999-2001) of National Health Interview Survey data yielded 96,501 adult respondents. Dependent variables were moderate, vigorous, and strengthening activity. Old boomers (1946-1955) and young boomers (1956-1965) were compared to respondents born before 1926, after 1975, and 10-year cohorts between. SUDAAN multiple logistic regression adjusted for complex sampling structure and multiply imputed income. Age-adjusted, older cohorts showed greater likelihood of activity than younger cohorts, offsetting moderate-activity declines with age until sharp decreases at advanced age: a plateau across Boomer and younger-aged cohorts. Interventions should promote activity at intensities and frequencies to which Boomers are most receptive.     

Reducing attrition in physical activity programs for older adults

This study investigated attrition in a 6-month physical activity intervention for older adults. The program was based on the social-cognitive theory incorporating self-efficacy factors. Two hundred forty-eight insufficiently active 65- to 74-year-olds were recruited from the Australian federal electoral roll. The intervention comprised walking and strength and flexibility exercises and was conducted in 30 local neighborhoods where the participants resided. Characteristics of individuals lost to attrition (n = 86, 35%) were compared with those of program completers (n = 162, 65%). Logistic-regression analysis showed that those lost to attrition came from areas of lower socioeconomic status, were overweight and less physically active, and had lower walking self-efficacy scores and higher loneliness scores. The results suggest that early assessment of these characteristics should be undertaken to identify individuals at risk of attrition, to improve retention, and to avoid potential bias.
