Previous research on the stereotype threat phenomenon has shown that inducing a negative stereotype toward a group debilitates motor performance despite the increase in motivation. Most of the studies focused on tasks requiring technical skills. However, what happens when the task does not require technical skills but focuses on energy expenditure? To examine this question, 34 male and female participants were assigned to a negative stereotype toward women and a nullified-stereotype condition and performed 20 min of self-paced cycling exercise. The authors hypothesized better performances when participants were assigned to the negative stereotype toward women condition than when assigned to the nullified-stereotype condition. As predicted, men and women increased their performances, accompanied by increases in heart rate. Concerning women, this result provides support for the notion that the effect of inducing a negative stereotype is task dependent, but further research is needed to more deeply investigate the mechanisms involved.

We conducted Men on the Move, a 12-week randomized controlled feasibility trial of a scalable, choice-based, physical activity (PA) and active transportation intervention. Participants were community-dwelling men aged 60 years and older (n = 29 intervention [INT] and n = 29 waitlist control [CON]). Trained activity coaches delivered: (a) one-on-one participant consultations to develop personal action plans for PA and active transportation, (b) monthly group-based motivational meetings, (c) weekly telephone support, (d) complimentary recreation and transit passes, and (e) pedometers and diaries for self-monitoring. Men on the Move demonstrated high rates of recruitment, retention, and intervention adherence. INT chose a variety of group-based and individual PAs and destinations for their personal action plans. At 12 weeks, INT achieved more steps, moderate–vigorous PA, and energy expenditure than CON. INT was also more likely to take transit and meet national guideline levels of PA. At 24 weeks follow-up, INT benefits were sustained for moderate–vigorous PA and energy expenditure.

We provide a systematic review of interventions utilizing mobile technology to alter physical activity, sedentary behavior, and sleep among adults aged 50 years and older. A systematic search identified 52 relevant articles (randomized control trial [RCT], quasi-experimental, pre/post single-group design). Of 50 trials assessing physical activity, 17 out of 29 RCTs and 13 out of 21 trials assessed for pre/post changes only supported the effectiveness of mobile interventions to improve physical activity, and 9 studies (five out of 10 RCTs and all four pre/post studies) out of 14 reduced sedentary behavior. Only two of five interventions improved sleep (one out of two RCTs and one out of three pre/post studies). Text messaging was the most frequently used intervention (60% of all studies) but was usually used in combination with other components (79% of hybrid interventions included SMS, plus either web or app components). Although more high-quality RCTs are needed, there is evidence supporting the effectiveness of mHealth approaches in those aged 50 years and older.

Increasing somatosensory information from the foot by exercising barefoot can potentially optimize the effectiveness of physical exercise interventions on falls prevention in the older adults. This pilot study was then undertaken to explore the effects of increased somatosensory information from the foot by exercising barefoot on balance, gait, and plantar cutaneous sensitivity in institutionalized older adults involved in multimodal exercise intervention. Participants were assigned to three groups: a control group which did not perform any physical exercise and two groups in which they were involved in a multimodal exercise program performed barefoot or shod. Postural, gait, and plantar cutaneous sensitivity parameters were collected. The results showed that the exercise program produced larger effects on balance and plantar cutaneous sensitivity when exercises were performed barefoot, without any noticeable effect on gait. Hence, barefoot exercising could be a relevant means to optimize the fall-prevention exercise programs in institutionalized older adults.

Background: Identifying parental perceived barriers might contribute to strategies to promote physical activity in children. This study aimed to observe parental perceived barriers for 6- to 10-year-old children’s participation in organized sports and understand to what extent the socioeconomic status, the place of residence, and children’s sex, age, and sport participation affect those perceived barriers. Methods: Data were collected from 834 parents of 6- to 10-year-old children living in the Portuguese Midlands, using a multiple-choice questionnaire. Parents reported the perceived barriers to children’s sport activities, such as time, health, transportation, costs, safety, facilities, weather, tiredness, and lack of interest. Children’s and sociodemographic characteristics were also collected. Results: Time and costs were the most reported barriers by parents. Barriers to access were mostly reported by parents of girls and younger children, parents of inactive children, and families living in an urban setting and in socioeconomic disadvantage. Perceived barriers differed according to both children’s and sociodemographic characteristics, highlighting the need to reduce costs and increase the variety of sports/facilities, particularly in families with girls, younger children, and those with lower incomes from more urbanized areas. Conclusions: The present findings should be considered in future planning and interventions to effectively promote physical activity in children.

Background: This study investigated associations between different types of sedentary behavior (SB) and physical activity (PA) in parent and their child, including the moderating effects of parent and child sex. Methods: In total, 1231 adolescents, 1202 mothers, and 871 fathers were evaluated. The SB (TV viewing + computer + video game); different types of PA (leisure-time PA, occupational PA, and total PA); and the socioeconomic level were evaluated by questionnaire. The relationship between adolescents’ SB and PA with parental characteristics was estimated by linear regression. Results: The SB of male adolescents was correlated to the father’s SB (β = 0.26; 95% confidence interval [CI], 0.13–0.39) and mother’s SB (β = 0.18; 95% CI, 0.06–0.31). A similar relationship was observed between SB of female adolescents and the father’s SB (β = 0.31; 95% CI, 0.19–0.42) and mother’s SB (β = 0.29; 95% CI, 0.20–0.38]). The SB of girls was inversely related to mother’s occupational PA (β = −2.62; 95% CI, −3.66 to −0.53]). The PA of the boys and girls was correlated with their fathers and mothers PA. All the results were adjusted for age and parent’s socioeconomic level. Conclusions: SB and PA of parents were associated with SB and PA of their children, regardless of gender. Strategies for health promotion should consider the family environment to increase PA and reduce SB.

Resistance training (RT) can maintain and improve physical and mental health in older adults, but this population has low levels of RT participation. Linking older people participating in RT (i.e., peers) with those who have not may promote and maintain adherence. This qualitative study explored the experience of peers in encouraging RT participation among older adults. Data were collected using focus groups, researcher observations, and semistructured interviews. Thematic analysis was conducted. Older people (n = 8) who engaged in RT prior to recruitment, participated as peers. Each provided peer support for between one and four RT participants for 6 weeks. The peer role was perceived by peers as potentially leading to a relationship which benefitted both parties. Peers reported that helping and supporting others was a positive experience and raised their self-efficacy. Difficulty initiating contact and differing expectations of peers and RT participants were viewed as challenges. Peer mentoring could help promote RT participation among older adults.

An understanding of physical activity attitudes, preferences, and experiences in older adults is important for informing interventions. Focus groups were conducted with 46 regionally-based Australian adults aged 65 years and older, who were not currently meeting activity recommendations. Content analysis revealed that participants mainly engaged in incidental activities such as gardening and household chores rather than planned exercise; however, leisure-time walking was also mentioned frequently. Although participants valued the physical and mental health benefits of physical activity, they reported being restricted by poor physical health, extreme weather, and fear of injury. Participants were interested in exercise groups and physical activity programs tailored to their existing physical health. The majority of participants reported preferring to be active with others. The findings from this study are useful in for informing future interventions specifically tailored to the needs of older adults in Australia.

Background: Health behaviors in childhood and adolescence are implicated in health behaviors and chronic disease risk in adulthood for the majority of the US population. However, little is known about these relationships in Hawaiian youth. This study investigated the extent to which childhood physical activity (PA) and fruit and vegetable consumption behaviors predicted later behaviors across a 10-year period in Hawaiian youth. Methods: Three cohorts of fourth- to sixth-grade students who participated in an elementary after-school program (Fun 5) provided baseline data (Y1—data collected between 2003 and 2007), 5-year (Y5—data collected between 2008 and 2012), and 10-year (Y10—data collected between 2013 and 2017) follow-up surveys. Demographic, PA, and fruit and vegetable consumption measures were completed at all 3 time points. Bivariate and multiple regressions were computed in 2018. Results: Y1 and Y5 behavior predicted PA in young adulthood. For fruit and vegetable consumption, Y1 behavior predicted Y5 behavior but not Y10 behavior, and Y5 behavior predicted Y10 behaviors. Conclusions: Similar to mainland US youth, it is important to address PA and nutrition early in the life span for Hawaiian youth to increase long-term preventive health behaviors and reduce long-term chronic disease risk.

Background: Despite holding great potential for addressing concerns regarding public health, recent systematic reviews have found effect sizes for interventions targeting physical activity to be small. Before interventions can be improved, the factors influencing outcomes must be identified. This systematic review aimed to identify predictors of success, measured in terms of engagement (eg, involvement duration) and health behavior change (eg, increased step counts), of workplace interventions targeting physical activity. Methods: A structured search of 3 databases (PubMed, PsycINFO, and Web of Science) was conducted to identify articles published between January 2000 and April 2017. For inclusion, articles needed to test a workplace intervention targeting physical activity and perform a quantitative analysis, identifying predictors of engagement or health behavior change. Results: Twenty-two studies were identified for review (median quality score = 70%). Demographic variables (eg, gender, age) were inconsistent predictors of success. However, employees in better health and physically active at baseline were found to have a greater likelihood of success. Conclusions: It appears that achieving successful results among employees at high risk of poor health outcomes remains a significant challenge for interventions. It is hoped that program developers can use this information to create effective interventions particularly for more sedentary employees.
