Fit Check: Making Health Assessments Work For You, Brooklynn Raacke, Ryssa Schlaefli, Caleb Ashley, Makenzie Premer, Brooke Mann, Jessica Phelan

SACAD: Scholarly Activities

When given multiple tools to assess health, people tend to choose the one that is most familiar, fastest, or easiest to interpret. Relying solely on weight can overshadow other important indicators of health, such as body composition, cardiovascular function, and muscular development. Understanding this preference, even when other tools are available, matters for both educators and fitness professionals. This study used naturalistic observation to assess gym-goers' usage of health and anthropometric assessment tools. Results indicated that while gym-goers initially showed interest in less commonly used assessment tools, they overwhelmingly used the scale. Implications, limitations, and future directions are discussed.

The aim of this paper is to understand the key aspects of physical activity culture in English primary schools using the organizational culture framework.

Methods: A four-month rapid ethnography study was conducted within three primary schools in Bristol, UK, between March and July 2024. The findings draw on observations, interviews, documentary data, photo elicitation, informal conversations and …

Simulated Hearing Loss In Healthy Young And Older Adults Results In Poor Reaction Time In Older Adults., Victoria Kowalewski, Nicoleta Bugnariu, Rita M. Patterson, Jessica Hartos

Pacific Journal of Health

Emerging evidence links hearing loss to increased fall risk in older adults, yet mechanisms remain unclear. This study examined the impact of simulated hearing loss on reactive balance control in healthy young and older adults. Participants performed dual-task scenario involving auditory sentence repetition and unexpected surface translations. Hearing loss was simulated using Adobe Audition, applying frequency-specific attenuation based on moderate sensorineural hearing loss levels from the literature.

Speech-in-noise performance significantly declined under simulated hearing loss for both age groups (p < .001), confirming effective simulation, but not significant differences were found between age groups. Maximum COP-COM displacement (the scalar distance between Center of Pressure and Center of Mass) increased with perturbation intensity (Level 1 vs. Level 2: p < .001), but no significant differences were found between hearing conditions or age groups (p > .05), suggesting compensatory step execution was preserved.

Reaction time analysis revealed a significant interaction between hearing condition and perturbation level …
