Impacts of Developmental Coordination Disorder on Postural Control Mechanisms in Children and Early Adolescents

Sirine Guetiti, Geneviève Cadoret, Félix Chénier, and Mariève Blanchet

Several studies have demonstrated balance impairments in children with developmental coordination disorder (DCD). However, a recent meta-analysis reports that none of the existing studies investigated the entire construct of balance across the same postural task. It is unclear whether anticipatory postural adjustments before voluntary unperturbed leaning tasks are altered in DCD. Anticipatory postural adjustment’s impact on postural control and limits of stability as well as the contribution of proprioception in these mechanisms are also unknown. This study compared the center of pressure displacements of participants with DCD (n = 30) to typically developing participants (n = 20) (9–12 years old). Standing on an AMTI force plate, participants were asked to lean as far as possible forward, backward, rightward, and leftward in both natural and with eyes closed + foam conditions (eight separated trials). The statistical analysis revealed that the DCD group had larger anticipatory postural adjustments, maximal center of pressure excursion, and greater postural instabilities than the control group. The proprioceptive condition does not systematically influence postural performance in DCD. These deficits are, however, increased in mediolateral directions. These impairments could interfere with children’s performance during daily and physical activities and even negatively impact social inclusion.

Inhibition of Ironic Errors and Facilitation of Overcompensation Errors Under Pressure: An Investigation Including Perceived Weakness

Hiroki Nakamoto, Shoya Hashimoto, Mio Kamei, Munenori Murata, Sachi Ikudome, Kenta Karakida, and Yoshifumi Tanaka

The conflicting predictions of ironic process theory and the implicit overcompensation hypothesis have been presented as a framework to explain the characteristics of errors that occur when a certain behavior is prohibited. The former predicts that instructions prohibiting a particular behavior will increase the likelihood of an outcome that should be avoided (ironic error), whereas the latter predicts that the likelihood of an outcome opposite of that to be avoided (overcompensation error) will increase. We examined how these errors, which negatively affect performance, are influenced by pressure and perceived weakness. Participants performed a tennis-stroke task, aiming to hit a ball toward a target zone while avoiding a discouraged zone. The results indicate that pressure decreases the ironic errors but increases the overcompensation errors that occur when a particular behavior is discouraged, while an increase in perceived weakness induces random errors.

Is Scotland Walking in the Right Direction? A Cross-Sectional Analysis of Trends in Walking by Socioeconomic Status

Tessa Strain, Paul Kelly, Rona Gibb, Mary Allison, Nanette Mutrie, and Marie Murphy

Background: Walking is a key target behavior for promoting population health. This paper charts the 30-year history of walking policy in Scotland. We assess whether population walking levels among adults in Scotland have changed in recent years and identify the characteristics of those least likely to report any walking. Methods: We pooled 9 years (2012–2019 and 2021) of data from adult (≥16 y) respondents of the Scottish Health Survey (n = 41,470). The outcomes of interest were the percentage reporting (1) any walking and (2) any walking with an average pace that is of at least moderate intensity. We also investigated the contribution of walking to total nonoccupational moderate to vigorous physical activity. We used linear and logistic regressions to test linear trends over time and to identify inequalities by age, sex, and the Scottish Index of Multiple Deprivation quintile. Results: There was an increase in all measures of walking over the period 2012–2021; for example, the percentage reporting any walking increased by 7 percentage points (81.4%–88.4%). Inequalities still exist by age, sex, and the Scottish Index of Multiple Deprivation but have not grown over time. Inequalities by sex and age are most pronounced in the least affluent Scottish Index of Multiple Deprivation quintiles; less affluent older women are least likely to report any walking. Conclusions: Scotland appears to be walking in the right direction. Surveillance data support a positive trend after decades of policy and promotion efforts. The policies do not appear to be exacerbating existing inequalities, but narrowing them will require more concentrated efforts.

agcounts: An R Package to Calculate ActiGraph Activity Counts From Portable Accelerometers

Brian C. Helsel, Paul R. Hibbing, Robert N. Montgomery, Eric D. Vidoni, Lauren T. Ptomey, Jonathan Clutton, and Richard A. Washburn

Portable accelerometers are used to capture physical activity in free-living individuals with the ActiGraph being one of the most widely used device brands in physical activity and health research. Recently, in February 2022, ActiGraph published their activity count algorithm and released a Python package for generating activity counts from raw acceleration data for five generations of ActiGraph devices. The nonproprietary derivation of the ActiGraph count improved the transparency and interpretation of accelerometer device-measured physical activity, but the Python release of the count algorithm does not integrate with packages developed by the physical activity research community using the R Statistical Programming Language. In this technical note, we describe our efforts to create an R-based translation of ActiGraph’s Python package with additional extensions to make data processing easier and faster for end users. We call the resulting R package agcounts and provide an inside look at its key functionalities and extensions while discussing its prospective impacts on collaborative open-source software development in physical behavior research. We recommend that device manufacturers follow ActiGraph’s lead by providing open-source access to their data processing algorithms and encourage physical activity researchers to contribute to the further development and refinement of agcounts and other open-source software.

Interventions Based on Behavior Change Techniques to Encourage Physical Activity or Decrease Sedentary Behavior in Community-Dwelling Adults Aged 50–70: Systematic Review With Intervention Component Analysis

Saima Ahmed, Kimberly Lazo Green, Lisa McGarrigle, Annemarie Money, Neil Pendleton, and Chris Todd

Increasing physical activity (PA) and/or decreasing sedentary behaviors is important in the delay and prevention of long-term conditions. PA can help maintain function and independence and decrease the need for hospitalization/institutionalization. Activity rates often decline in later life resulting in a need for interventions that encourage uptake and adherence through the use of Behavior Change Techniques (BCTs). We conducted a systematic review of the evidence for interventions that included BCTs in community-dwelling adults with a mean age of 50–70. The review followed PRISMA guidelines. The interventions were psychosocial, nonpharmacological, and noninvasive interventions utilizing components based on BCTs that evaluated change in PA and/or sedentary behavior. Intervention Component Analysis (ICA) was used to synthesize effectiveness of intervention components. Twelve randomized controlled trials were included in this review. The mean sample age was 50–64. Thirteen BCTs were used across all studies, and the most commonly used techniques were goals and planning, feedback and monitoring, and natural consequences. Seven intervention components linked with BCTs were found: personalized goal setting, tailored feedback from facilitators, on-site and postintervention support, education materials and resources, reinforcing change on behavior and attitudes, self-reported monitoring, and social connectedness. All components, except for social connectedness, were associated with improved health behavior and PA levels. The interventions that use BCTs have incorporated strategies that reinforce change in behavior and attitudes toward PA.

Is It Possible to Decolonize the Field of Physical Activity and Health?

Alan G. Knuth, Giulia Salaberry Leite, Sueyla Ferreira da Silva dos Santos, and Inácio Crochemore-Silva

Is it possible to decolonize the field of physical activity and health? Decoloniality presupposes a body-geopolitical location, such as in the Brazilian and Latin American context, where it is crucial to use social identity lenses related to race, gender, sexuality, and other social markers that affect the body. Understanding health and physical activity from a decolonial perspective would bring the oppressions that connect capitalism, patriarchy, and racism to the center of the discussion. For a “physical activity other,” we challenged the general recommendation of physical activity in the 4 domains. Physical activity should be understood as an end in itself, as a right, and as human development. Approaches that advocate physical activity at work, at home, and while commuting use other human activities to relate these domains to health without considering the inequalities and oppressions that constitute them in most parts of the world. Is it fair to apply “global recommendations” for physical activity to scenarios such as Brazil and Latin America, using models that are inappropriate to the context and history of these places, people, and cultures? Perhaps it is time to socially reorient and reposition physical activity from a decolonial perspective. We need Black, Indigenous, Latino, African, and other people from the Global South to move the research agenda, recommendations, and policies on physical activity from “any” health to a fair health.
