Background:

Social support can influence physical activity among some individuals. This study examined the effect that social support has on adolescents’ physical activity and their perceived barriers and benefits to exercising.

Methods:

A survey was completed by adolescents (N = 535) at 2 single-sex (1 male, 1 female) high schools in Ohio.

Results:

Adolescents who received parental encouragement to exercise and who had an exercising friend engaged in significantly more days of physical activity in the past week than did their counterparts. Perceived benefits of physical activity differed significantly based on whether the respondent received parental encouragement and had a friend who exercised. Social support for physical activity significantly affected adolescents’ perceptions of and engagement in physical activity.

Conclusions:

Parents should encourage their children to become physically active and partner with peers when exercising.

This study aimed to identify barriers and facilitators associated with walking for exercise among people who experience intermittent claudication. Fifteen individuals (7 men and 8 women) participated in 3 focus groups that were tape-recorded and content analyzed. A social-cognitive framework was used to categorize barriers and facilitators as those related to the person, to the activity, or to the environment. Variables identified included those specific to intermittent claudication and those common among the general population. Barriers to walking included irregular or graded walking surfaces, uncertainty about the outcome of walking, ambiguity regarding pain, the need to take rest breaks, and the presence of leg pain. Facilitating factors included availability of a resting place, use of cognitive coping strategies, companionship support, and availability of a treadmill-walking program. Findings are interpreted in light of current research on exercise determinants and encourage prospective examinations of the predictive validity of these factors for walking.

In a cross-sectional survey, older Australians (N = 402) were asked to report their physical activity habits and the 3 main barriers to more physical activity. Active and inactive men and women differed only in how many reported being sufficiently active or that their health was too poor to be more active. Six barriers were reported by more than 10% of inactive men and women: “already active enough,” “have an injury or disability,” “poor health,” “too old,” “don't have enough time,” and “I'm not the sporty type.” Insufficient time was identified by significantly fewer respondents as age increased. More respondents 65–70+ years old identified poor health as a barrier than did those 60–64. The proportion who had an injury or disability decreased from 60–64 to 65–69 and increased markedly among those 70+. Programs for older adults should take into account the age of the target group and the limitations imposed by poor health or disability.

To better understand mechanisms of physical activity (PA) behavior change in breast cancer survivors, we examined mediation of a successful PA behavior change intervention by social cognitive theory (SCT) constructs. Our exploratory study randomized 41 breast cancer survivors to receive the 3-month intervention (INT) or usual care (UC). We used the Freedman and Schatzkin approach to examine mediation of intervention effect on PA 3 months postintervention by changes in SCT constructs from baseline to immediately postintervention. Compared with UC, the INT group reported lower barriers interference (mean difference = −7.8, 95% CI [−15.1, −0.4], d = −0.67, p = .04) and greater PA enjoyment (mean difference = 0.7, 95% CI [0, 1.5], d = 0.61, p = .06). Barriers interference mediated 39% (p = .004) of the intervention effect on PA 3 months postintervention. PA enjoyment was not a significant mediator. Reducing barriers to PA partially explained our intervention effect.

This study attempts to measure quantitative and qualitative dimensions of leisure time in an effort to see how they are related to the sport participation rates of women and men. Using data collected from a sample of 83 women and 128 men—all of whom were employed, married parents—it was found that women did more housework than men did but the time spent on housework did not account for differences in participation rates for either women or men. Most important in explaining participation in sports among women was the average number of hours per week their spouses were away from home in the evenings. On the basis of these findings it was concluded that the quantitative dimensions of leisure were not associated with sport participation rates; however, the qualitative dimensions of leisure were associated with barriers to participation for women but not for men. The data suggested that compared to men, women were less likely to feel they had the freedom to participate in sport. This difference was explained in terms of a combination of factors including differential socialization and different patterns of motivation related to sport participation among women and men.

The purpose of this study was to investigate the differences in skin temperature during ice application through a dry towel and a dry elastic bandage compared to application on bare skin. Nine subjects completed a 30-min treatment session that consisted of 0.68 kg of cubed ice applied under three conditions: through a dry towel, through a dry elastic bandage, and directly on the skin (control). Following the removal of the ice, all subjects were monitored for 20-min for skin temperature (S temp). There was a significant interaction in S temp between the control (12.50 ± 4.39 °C) and dry towel (23.48 ± 2.88 °C) conditions, the control (12.50 ± 4.39 °C) and dry elastic wrap (27.47 ± 2.36 °C) conditions, and the dry towel (23.48 ± 2.88 °C) and dry elastic wrap (27.47 ± 2.36 °C) conditions. The findings indicated that using a barrier (dry towel or dry elastic bandage) limits the temperature-reducing capacity of the ice and therefore its potential physiological effects.

Background:

Perceived barriers are modifiable correlates of participation in physical activity. Associations of specific perceived barriers with participation in and level of walking for recreation, and other leisure-time physical activity (LTPA) were examined. Personal, social, and environmental factors associated with these perceived barriers were then examined.

Methods:

From 2003 to 2004, 2 surveys collected data on recreational walking and other LTPA, perceived barriers to participation, and personal, social, and environmental attributes, from 2194 Australian adults. Zero-inflated negative binomial regression models examined associations of perceived barriers with walking and other LTPA. Generalized linear models identified the correlates of these perceived barriers.

Results:

The perceived barriers of lack of motivation and time were associated with level of LTPA, while lack of motivation, poor health, and lack of facilities were associated with the odds of non-participation in LTPA. Personal, social, and environmental factors independently contributed to variations in perceived barriers.

Conclusions:

Level and likelihood of participation in LTPA are associated with different perceived barriers. Perceived barriers are a function of both nonmodifiable personal factors and potentially modifiable personal, social, and environmental factors. These findings suggest that the provision of relevant environmental opportunities and social support may effectively reduce perceived barriers to LTPA.
