Preschoolers with developmental delay (DD) are at risk for poor fundamental movement skills (FMS), but a paucity of early FMS interventions exist. The purpose of this review was to critically appraise the existing interventions to establish direction for future trials targeting preschoolers with DD. A total of 11 studies met the inclusion criteria. Major findings were summarized based on common subtopics of overall intervention effect, locomotor skill outcomes, object-control outcomes, and gender differences. Trials ranged from 8 to 24 weeks and offered 540–1700 min of instruction. The majority of trials (n = 9) significantly improved FMS of preschoolers with DD, with a large intervention effect (η2 = 0.57–0.85). This review supports the utility of interventions to improve FMS of preschoolers with DD. Future researchers are encouraged to include more robust designs, a theoretical framework, and involvement of parents and teachers in the delivery of the intervention.

Background:

Interactive stationary bikes provide positive affective experiences and physiological benefits; however, research is limited.

Methods:

This study compared usage of GameBikes to traditional stationary bikes among families in the home following a 6-week randomized, controlled trial design. Parents completed questionnaires featuring constructs of the theory of planned behavior (TPB). Usage was tracked by all family members and belief elicitation with GameBike families followed the trial.

Results:

Usage across the trial was significantly different for children in favor of the GameBike group (t 36 = 2.61, P = .01, d = .85). No differences were identified for parents. Significant time effects for parents’ (F 5,48 = 5.07, P < .01; η2 = .35) and children’s (F 5,32 = 8.24, P < .01; η2 = .56) usage were found with declines across 6 weeks. Affective attitude was the only significant TPB variable between groups at both time one (t 57 = 2.53, P = .01; d = .65) and follow-up (t 52 = 2.70, P = .01; d = .74) in favor of the GameBike group. Elicited beliefs were primarily affective- and control-based.

Conclusions:

The results provide support for use of interactive video games to augment current PA initiatives. Larger-scale trials with longer durations are warranted.

Background:

The current physical activity (PA) and health-related quality of life (HRQoL) literature warrants further investigation with general population samples. The exploratory-focused purpose of this study was to compare total PA-HRQoL and walking-HRQoL relations, include a measure of general happiness, and to evaluate potential activity-HRQoL demographic moderators.

Methods:

A random sample of 351 adults completed an adapted Godin Leisure Time Questionnaire, the SF-36, and the Satisfaction with Life Scale.

Results:

Partial correlations revealed small-to-moderate associations between walking/total PA and general health, vitality, and social functioning after controlling for key demographics (P < 0.05). A dependent t-test determined walking and PA as equally related to vitality and social functioning. Multiple regression revealed annual income as a moderator of the total PA/walking-social functioning relationship [F(3,315) = 9.71 and F(3,316) = 12.03, P < 0.01, respectively].

Conclusions:

HRQoL may be considered with walking interventions and annual income. The contribution of PA to overall happiness appears to be minor.

Age and gender are consistently related to physical activity (PA), yet theoretical explanation for these associations is scant. The present study compared the mean values and correlations of a population sample, divided by gender and age group, with respect to theory of planned behavior beliefs (behavioral, normative, and control) and PA. Participants were a sample (N = 6,739) of adults (M age = 49.65, SD = 16.04) who completed measures of social and health demographics, theory of planned behavior beliefs, and self-reported PA. Mean analyses identi-fed greater perceived control over PA for seniors than for young and middle-aged adults (η2 > .025). Belief–behavior correlations, however, were not different across age and gender in 24 of 26 tests (q < .19). Thus, PA beliefs are invariant across age and gender with the exception of mean levels of perceived control, which are lower among younger adults than older adults. Factors such as early parenthood and career demands were considered the likely reasons for differences. Overall, the evidence suggests that adapting theoretical models for specific age groups or based on gender may not be necessary.

This study investigated the moderating influence of the five-factor model of personality (FFM) on the theory of planned behavior (TPB) in the exercise domain. Although an analysis of all possible moderation effects was conducted, it was hypothesized that high extraversion (E) and conscientiousness (C) individuals would demonstrate significantly stronger relationships between intentions and exercise behavior than those low in E and C. Conversely, it was expected that high neuroticism (N) individuals would show a significantly weaker relationship between intention and exercise behavior than those low in N. A total of 300 undergraduate students completed measures of the FFM, TPB, and a 2-week follow-up of exercise behavior. Two-group structural equation models of the TPB were created using a median split for each personality trait. Overall, 5 significant (p < .05) moderating effects were found. Specifically, N was found to moderate the effect of subjective norm on intention. E also moderated the effects of subjective norm on intention as well as intention on behavior. C moderated the effects of affective attitude on intention and intention on behavior. Theorized influences for the presence or absence of personality moderators are discussed. The results generally support the possibility of personality being a moderator of the TPB but highlight the need for future research and replication.

Despite its well-established benefits, physical activity engagement is low in the adult population; evidence suggests that this is especially a concern for women >60 years. The purpose of this mixed methods study was to explore the feasibility of a 6-week randomized control trial of self-determination theory-based dance and walking programs for older women. Primary outcomes were feasibility measures: recruitment, retention, and satisfaction. Secondary outcomes included self-reported physical activity, behavioral regulations, and psychological needs. Thirty-five women completed the study (M = 62.8 ± 4.8 years), representing 39% recruitment and 95% retention rate. Both programs were highly attended. Exploratory effect sizes for secondary measures were promising. Emergent themes highlighted the importance of servant leadership concepts in the group setting for motivating physical activity. Our findings provide support for expanding this trial to a full-scale study.

Background:

Nearly 50% of U.S. women enter pregnancy as overweight or obese (OW/OB). There is a critical need to understand how to motivate OW/OB pregnant women for exercise behavior to improve their health and reduce adverse pregnancy outcomes.

Purpose:

To examine salient Theory of Planned Behavior belief predictors of normal weight (NW) and OW/OB pregnant women’s exercise behavior (EXB) across pregnancy.

Methods:

Pregnant women (N = 357) self-reported their exercise beliefs and behavior during each pregnancy trimester. Pearson correlations were used to examine exercise beliefs-behavior associations. Stepwise regressions were used to identify trimester (TRI) 1 and TRI 2 belief predictors of TRI 2 and TRI 3 EXB, respectively, for each weight status group. Belief endorsement was examined to identify critical beliefs.

Results:

TRI 1 EXB beliefs explained 58% of the total variance (22% NW, 36% OW/OB) in TRI 2 EXB. TRI 2 EXB beliefs explained 32% of the total variance (17% NW, 15% OW/OB) in TRI 3 EXB. Individual beliefs varied by weight status and trimester. Control beliefs emerged with the lowest endorsement; making them most critical to target for exercise interventions.

Conclusion:

Prenatal exercise interventions should be weight status specific and target salient beliefs/barriers unique to the pregnancy trimesters.

The impact of a six-week indoor wall climbing on the perceptions of self for children with special needs aged 6–12 years was explored. Participants (n = 46) were randomly assigned to the intervention (girls, n = 4; boys, n = 19) and control groups (girls, n = 5; boys, n = 18). Belayers’ and children’s perceptions of efficacy were measured using specifically designed questionnaires and perceptions of competence and global self-worth were measured using Harter’s (1985) Self-Perception Profile for Children for participants with an adaptive age of 8 years or higher. Children’s self-efficacy and belayers’ ratings of children’s efficacy improved significantly, t(21) = 3.9, p = .001, d = .84 and F(2, 44) = 30.03, p < .001, respectively. The children’s judgments of their athletic and social competence and global self-worth, however, did not change over time or differ from the wait-listed control group (p > .05). These results suggest that it is likely that many experiences that enhance self-efficacy may be needed to improve self-perceptions.

Background: A recent randomized controlled trial found that an intervention focused on developing an exercise habit increased weekly minutes of moderate to vigorous physical activity (MVPA) over 8 wk compared to a control group. The purpose of the current study was to test if changes in habit, as well as other behavioral strategy constructs from the Multi-Process Action Control Test, mediated between group condition and MVPA (self-report and accelerometry). Methods: Inactive new gym members (N = 94) were randomized into control or experimental (habit-building) groups. Results: No construct entirely explained mediation condition (experimental and control) and changes in MVPA measured by accelerometry. Self-report MVPA found affective judgments, behavioral regulation, and preparatory habit to be mediated between group (experimental/control conditions) and changes in behavior (β = 0.36, 95% confidence interval [.05–.78]). Conclusions: Self-reported and objectively measured behavior models demonstrated complete and partial mediation, respectively. New gym members could benefit from successful behavioral enactment by developing constructs to support habit formation.

The purpose of this study was to use the constructs of the theory of planned behavior (TPB) to gain a better understanding of the factors influencing older adults’ participation in strength training. Two hundred men and women age 55 years and older were purposely sampled from seniors’ centers in Ontario Canada. Participants completed a TPB questionnaire and reported their current physical activity participation. It was hypothesized that perceived behavioral control followed by attitude would be the strongest determinants of strength-training intentions and that intention would be the strongest determinant of strength-training behavior. Regression analyses revealed that subjective norm and perceived behavioral control explained 42% of the variance in intention and intention explained 40% of the variance in behavior. Gender and current strength-training participation did not significantly moderate the relationship between the TPB variables. The results suggest that interventions targeting subjective norm and perceived control might be helpful in promoting strength-training behavior among older adults.
