A Conditional Process Model of Children’s Behavioral Engagement and Behavioral Disaffection in Sport Based on Self-Determination Theory

Thomas Curran, Andrew P. Hill, and Christopher P. Niemiec

The potential benefits of children’s engagement in sport for their psychological, social, and physical health are well established. Yet children may also experience psychological and social impairments due, in part, to a variety of detrimental coach behaviors. In the current study, we proposed and tested a conditional process model of children’s self-reported behavioral engagement and behavioral disaffection in sport based on self-determination theory. Results from a sample of 245 youth soccer players suggested that structure from coaches related positively to behavioral engagement and negatively to behavioral disaffection, and that these relations were mediated by athletes’ basic psychological need satisfaction. Importantly, and in line with our hypotheses, these indirect effects were moderated by autonomy support from coaches, such that the mediation was evident only among those who reported higher levels of autonomy support. These findings underscore the importance of coaches’ providing guidance, expectations, and feedback (i.e., structure) in a way that respects athletes’ volition (i.e., autonomy support).

A Phenomenological Evaluation of the Psychological Factors That Influence Motorsports Performance

Christopher R. Hill, Kathleen T. Mellano, Haley B.P. Trujillo, and David P. Ferguson

Race car drivers not only face high-speed challenges but also need to manage complex team dynamics and sponsor relations and are exposed to unique fan access while competing. This study examines the unique psychological aspects of motorsports and how race car drivers currently train psychological skills to match these distinctive demands. Adopting a phenomenological approach, this study involved semistructured interviews with 11 professional race car drivers. The interviews focused on drivers’ psychological experiences during racing and their psychological preparation. Thematic analysis of the interview data revealed key psychological factors impacting performance. These included concentration, confidence, anxiety, managing emotional states, unique social aspects, and motivation. Drivers also had an interest in psychological-skills training but reported a lack of resources and consistent application. This study highlights the unique psychological challenges presented in motorsports, and the findings underscore the need for targeted psychological-skills training and resources for race car drivers.

The Relationship Between Barrier Self-Efficacy and Physical Activity in Children and Adolescents: A Meta-Analysis

Christopher R. Hill, Deborah L. Feltz, Stephen Samendinger, and Karin A. Pfeiffer

Previous reviews have highlighted the importance of self-efficacy beliefs in maintaining adequate levels of childhood physical activity (PA), but variable findings with different age groups and measures of PA indicate the need to quantify the extant literature. The purpose of this meta-analysis was to estimate the relationship between adolescents’ barrier self-efficacy (BSE) and PA behavior using a random-effects model and to examine age and type of PA measurement as potential relationship moderators. A systematic online database review yielded 38 articles up to June 2018. A small to moderate correlation between BSE beliefs and PA was noted, although the variability was considerable. Age and measurement timing were not significant moderators, but the type of measurement was a significant relationship moderator. This meta-analysis emphasizes the importance of BSE as a psychosocial correlate to PA behavior in young people. There is a need for further BSE–PA research with attention to measurement technique and developmental differences.

Changes in Physical Activity and Sedentary Behavior in a Randomized Trial of an Internet-Based Versus Workbook-Based Family Intervention Study

Victoria Catenacci, Christopher Barrett, Lorraine Odgen, Ray Browning, Christine Adele Schaefer, James Hill, and Holly Wyatt

Background:

The America on the Move (AOM) Family Intervention Program has been shown to prevent excess weight gain in overweight children. Providing intervention materials via the internet would have the potential to reach more families but may increase sedentary behavior. The purpose was to evaluate whether delivering the AOM Family Intervention via the internet versus printed workbook would have a similar impact on sedentary behaviors in children.

Methods:

131 children (age 8–12) were randomized to receive the AOM Family Intervention via the internet or workbook for 12 weeks. Changes in objectively measured sedentary time and moderate-to vigorous physical activity (MVPA) as well as self-reported screen time were compared between groups.

Results:

There were no significant differences between groups in screen time, sedentary time, or MVPA at the end of the 12 week intervention. Families receiving the intervention via the internet were more likely to remain in the study (98% vs. 82%, P = .016).

Conclusions:

Using the internet to deliver the lifestyle intervention did not increase sedentary behavior in children. Attrition rates were lower when the program was delivered by internet versus via printed materials. These results provide support for using the internet to deliver healthy lifestyle programs for children.

Why Residuals Are Important in the Self-Efficacy–Performance Relationship Analysis: A Study Across 12 Cycling Sessions

Stephen Samendinger, Christopher R. Hill, Teri J. Hepler, and Deborah L. Feltz

Background: The positive role of self-efficacy in directing a wide range of health-related interventions has been well documented, including those targeting an increase in physical activity. However, rarely do researchers control the influence of past performance and past self-efficacy perception ratings when exploring the interaction of self-efficacy and performance, allowing for a refined understanding of this relationship and the unique contribution of each factor. Methods: A residualized past performance, residualized self-efficacy hierarchical regression model was used to examine the effect of prior past performance and pre-exercise self-efficacy on performance with a health-related task (12 aerobic exercise cycling sessions). Results: The previous day’s residualized performance was a significant predictor of performance, as was same-day residualized self-efficacy (P < .001). However, residualized self-efficacy became a stronger predictor over time. Conclusions: While maintaining a consistent level of moderate–vigorous physical activity over 12 exercise sessions, participants increased their ratings of task self-efficacy, explaining an increasing portion of the variance in the self-efficacy–performance relationship days 9 to 12.

The Köhler Motivation Gain Effect With Exercise Tasks: A Meta-Analysis

Stephen Samendinger, Christopher R. Hill, Soyeon Ahn, and Deborah L. Feltz

The purpose of this meta-analysis was to examine the Köhler motivation effect in partnered dyads (conjunctive task structure) during exercise. This preregistered meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and included 19 (total sample size N = 1,912) primary, peer-reviewed research articles that have reported the effectiveness of the Köhler effect paradigm (with a no-partner control condition) in exercise tasks on the outcome variable of intensity or persistence of effort. The overall motivation gain effect was statistically significant, g ¯ ppc = 0 . 91 (SE = 0.12), suggesting a significantly higher performance gain in conjunctive partnered exercise groups compared with individual exercise. The large effect was moderated by the performance-dependent variable (persistence and intensity), mean participant age, and exercise partner type (human and software generated). There appears to be strong support for the Köhler motivation gain paradigm as a potential to help individuals improve their effort in exercise settings.

An Investigation of the Sled-Push Exercise Using a Resisted Sled Machine in Apparently Healthy Older Adults: An Exploratory Study

Micheal Baumann, Christopher Hill, Clayton Camic, Peter Chomentowski, Vitor Siqueira, Steven Petruzzello, and Emerson Sebastião

Physical function is regarded as the cornerstone of healthy aging, and exercise is an important determinant of healthy aging. This study examined the feasibility and physiological (heart rate, blood pressure, blood lactate, and rate of perceived exertion) and psychological (enjoyment) response resulting from an acute progressive sled-push (SLP) exercise session using the novel XPO Sled Trainer in older adults and compared that with walking (WKC) condition. The exercise session comprised six exercise bouts at 75%, 85%, 100% (2×), and 125% (2×) of normal velocity with a 2-min rest between bouts. Thirty-six older adults were randomly allocated into either the SLP or WKC conditions. No adverse events were observed during the exercise session, and all participants completed the exercise protocol as prescribed. One-third of the participants in the SLP group reported minimal body discomfort. Significantly higher responses were observed for all physiological variables as the intensity of the exercise increased in the SLP group compared with the WKC group (p < .001). The SLP group presented a decline in enjoyment as the intensity of the exercise increased (during), but similar enjoyment level than the WKC group for the overall exercise session (p = .711). Our findings support the viability and safety of SLP exercise using the XPO Sled Trainer in older adults. Such exercise demonstrated an intensity-driven modality that may have potential to elucidate positive adaptations in the cardiovascular system of older adults with acceptable levels of enjoyment.
