Older adults often suffer an accidental fall when navigating challenging surfaces during common locomotor tasks, such as walking and ascending stairs. This study examined the effect of slick and uneven surfaces on lower limb joint work in older and younger adults while walking and ascending stairs. Fifteen young (18–25 years) and 12 older (>65 years) adults had stance phase positive limb and joint work quantified during walking and stair ascent tasks on a normal, slick, and uneven surface, which was then submitted to a two-way mixed model ANOVA for analysis. The stair ascent required greater limb, and hip, knee, …

Context: The influence of several psychological characteristics on the willingness of athletes to report concussion behaviors has not been well explored. Therefore, the purpose of this study was to understand how athletic identity and sport passion predicted participants’ willingness to report symptoms above what was explained by athlete demographics, concussion knowledge, and perceived seriousness of concussions. Design: The study was cross-sectional. Methods: Three-hundred and twenty-two male and female high school and club sport athletes completed survey measures of concussion knowledge, athletic identity, harmonious and obsessive passion, and degree to which athletes indicated they would report concussions and …


Once You See It, You Can’T Unsee It?: Racial Justice Activism And Articulations Of Whiteness Among White Collegiate Athlete Activists, Yannick Kluch, Emma Calow, Eric M. Martin, Travis R. Scheadler, Andrew Mac Intosh, Shannon Jolly Sep 2023

The goal of this study was to examine how athletes holding privileged racial identities understand their whiteness as they engage in racial justice activism. Drawing from 12 semistructured interviews with white collegiate athletes who have engaged in activism for racial justice, we identified four higher order themes which we situate within a broader discussion of how each theme either reinforces or disrupts racial power: articulations of (a) racial consciousness, (b) white privilege, (c) white empathy, and (d) white accountability. While the white accountability theme has the potential to disrupt racial power due to its relying on rigorous self-critique, the remaining …

The purpose of this study was to investigate the effect of required remote work on work–family spillover within U.S. college sport. In particular, we examined the changes in work–family spillover (positive and negative), job commitment, and workaholism as employee’s work environment changed from traditional work expectations to work from home, and if these changes were, at least partially, due to parental responsibilities. Data were collected from full-time, National Collegiate Athletic Association (NCAA) athletic department employees (n = 1,139) in November 2019 and again in May 2020 following the onset of the COVID-19 pandemic and after the transition to remote …

On The Reproducibility Of Power Analyses In Motor Behavior Research, Brad Mckay, Mariane F. B. Bacelar, Michael J. Carter

Recent metascience suggests that motor behavior research may be underpowered, on average. Researchers can perform a priori power analyses to ensure adequately powered studies. However, there are common pitfalls that can result in underestimating the required sample size for a given design and effect size of interest. Critical evaluation of power analyses requires successful analysis reproduction, which is conditional on the reporting of sufficient information. Here, we attempted to reproduce every power analysis reported in articles (k = 84/635) in three motor behavior journals between January 2019 and June 2021. We reproduced 7% of analyses using the reported information, …
