Daily Movement Activities Are Associated With Within-Person Instability Of Cognitive Function In Older Adults: Evidence From An Ambulatory Assessment Study, Chih-Hsiang Yang, Donald Hedeker, Jongwon Lee, Halle Prine, Donna Coffman, Jingkai Wei, Jonathan George Hakun

Faculty Publications

Background and Objectives

Physical inactivity and excessive sedentary time (ST) are associated with poor cognitive health in older adults. However, current literature largely relies on cross-sectional designs or in-lab cognitive assessments, which do not adequately reflect cognitive function in naturalistic settings. Further, existing studies have largely overlooked the variability or the instability in daily cognitive function, which represents a critical marker of cognitive decline. This ambulatory assessment study examined the temporal associations of daily movement behaviors with the mean levels and the variability of cognition among older adults at risk of dementia.

Sensory Integration Processes Characterize Concussed Athletes With Balance Deficits, Bhagyashree Singh, Ingo Helmich

Exercise and Sport Studies: Faculty Publications

Impaired postural control constitutes a major symptom after mild traumatic brain injuries (mTBI/sport-related concussions (SRC)). In order to uphold cognition and behavior during pathological situations, individuals may be characterized by neuronal upregulation. Because postural control necessitates the integration of sensory information within somatosensory (/parietal) cortices, we investigated the hypothesis that athletes with ongoing symptoms after SRC are characterized by increased brain activation within these areas in order to compensate for postural deficits. Sixty-six athletes (27 ± 13 years; 50 men, 16 women) participated in the study. Twenty-two concussed athletes reported high post-concussion symptoms (PCS; symptomatic group), and 22 concussed athletes …

Cancer cachexia (CC) is marked by severe skeletal muscle loss and dysfunction, associated with mitochondrial degeneration. Our previous studies showed induction of the mitophagy marker BNIP3 3-wk post-Lewis lung carcinoma (LLC) induction. We hypothesize that excessive mitophagy contributes to muscle wasting in CC. To test this, we used a Bnip3 knockout (KO) mouse model with LLC-induced CC to assess its impact on muscle outcomes. Eight-wk-old male and female mice were injected with 1 x 10(6) LLC cells or PBS (sham controls). After 4 wk, we assessed muscle function through dorsiflexor electrophysiology, muscle protein synthesis via deuterium oxide labeling, and mitochondrial …

Voluntary Contractions Underestimate Peak Muscle Activity In Drop Jumps, David Alan Phillips, Skylar Paletta, Michael R. Perlet

Department of Kinesiology Scholarship and Creative Works

Maximal voluntary isometric contractions (MVIC) are a common method to normalize electromyographic amplitude into standardized units of %MVIC. However, in 60% of drop jump research using an MVIC in 2018–2023, supramaximal activation or activation greater than 100% MVIC occurred. Therefore, MVICs may not be representative of peak muscle activation, leading to erroneous interpretation of muscle activation. The purpose of this study is to quantify EMG normalization difference in drop jump landings. Sixteen (10 M, 6F) participants were recruited for the study. MVICs were recorded from nine lower extremity muscles and this activation compared to the maximal activation recorded from 10 …

However, the effect was not lasting and the working mechanisms was unclear. The purpose of this study is to determine the behavioral and neurophysiological effects of five daily sessions of tDCS on PSF.

Methods and analysis

This will be a double-blind randomized controlled trial targeting an enrollment of 32 participants with subacute-chronic stroke and significant fatigue (average Fatigue Severity Scale (FSS) > 4). Participants will be equally randomized to either anodal tDCS or sham tDCS …

Effect Of In-Season Potentiation And Priming On Jump Height In Collegiate D1 American Football Players, Benjamin Dagostino, Kody Cooke, Paulette Yamada, Trevor Short

Topics in Exercise Science and Kinesiology

Neuromuscular priming and post-activation potentiation (PAP) are techniques utilized to increase nervous system excitation, muscle force, and rate of force development during subsequent muscle contractions in sport. PAP is a commonly used approach that has the potential to influence neuromuscular status monitoring and flagging, and optimize power training. Specifically, jump height is an important parameter in athletic performance and assessing inter-limb asymmetries. Thus, the purpose of this paper is to report the effects of different PAP strategies on jump height during a competitive D1 American football season.

Walk A Mile: Exploring Cause-Based Charity Event Participation As A Catalyst For Increasing Physical Activity Behavior, Kimberly S. Fasczewski, Andrey A. Sanko Posada, Meg Hopkins

Journal of Social, Behavioral, and Health Sciences

Despite the known benefits of physical activity (PA), more than half of U.S. adults do not meet the American College of Sports Medicine’s PA recommendations for health, often resulting in negative health outcomes. Developing programming that increases motivation for PA participation is critical for healthcare professionals to combat physical inactivity. Previous research has demonstrated that framing disease-based PA charity fundraising events as “helping a cause” improved motivation for PA due to the individual’s emotional connection to the cause. There is currently no congruent research on motivation for participation in cause-based charity events. Behavioral economics theory posits that cognitive, emotional, and …

Physical Activity And Body Image In Early Onset Cancer Patients, Madeleine Z. Pollard

Graduate Masters Theses

Abstract: Cancer is the leading cause of death among Americans under the age of 85 (Brown et al., 2012). There are increasing rates of cancer diagnoses in adults aged 18-49, which is described as an early onset (EO) diagnosis. Despite high survival rates (Lewis et al., 2021), EO cancer patients are at increased risk for long-term physical and psychological challenges associated with both the disease and its treatment (Haque et al., 2023). Cancer diagnosed during these critical periods of life can significantly impact self-perception and body image, which are critical to identity formation and quality of life (Castonguay, et al., …

Aging-Induced Increase In Top-Down Connectivity From Dlpfc To Sma/M1 And Decrease In Inter-Limb Motor Coordination During Standing Tasks, Jiahao Pan, Shuqi Zhang

International Journal of Physical Activity and Health

This study aimed to investigate the effects of aging on inhibitory control from the prefrontal cortex (PFC) to the motor cortices and inter-limb coordination during dual task standing. Participants performed single-task and dual-task standing. Ground reaction force, center-of-pressure, muscle activity, and cortical activation were measured. The older group showed a greater effective connectivity index from the intra-hemispheric dorsolateral PFC (DLPFC) to supplementary motor area (SMA) (right, p = 0.009; left, p = 0.003) and left DLPFC to right M1 (p = 0.020)than the young group across task conditions. Also, the older group had greater inter-tibialis anterior coherence at 15–35 …

It Is Not Clear How Well Physical Activity Promotion Materials Are Understood: Findings From A Rapid Literature Review, Jafra D. Thomas, Jasmine C. Wong, Regina F. Hockert, Yi Sheng Wu, Winston Kennedy

Topics in Exercise Science and Kinesiology

Topics in Exercise Science and Kinesiology Volume 6: Issue 1, Article 6, 2025. Efforts to promote physical activity and other health-related behaviors are more effective when resource materials are understood by a wide and diverse audience. Before our lab’s previous investigations (Thomas et al., 2024), only one study seemed to use the cloze procedure to directly test the comprehension (i.e., readability) of physical activity promotion material (Cardinal & Seidler, 1995). Thus, this rapid literature review sought to (a) determine the extent the cloze procedure has been used to study physical activity promotion material comprehension in lay adults and (b) collate …
