High-density and low-density lipoproteins (HDL and LDL) are established analytical targets for diagnosis and risk stratification of numerous chronic diseases. This study investigates potential sources of bias in lipoprotein particle counting (HDL-P and LDL-P), focusing on the most atheroprotective small-HDL and most pro-atherogenic small-LDL. Plasma samples were fractionated using asymmetric-flow field-flow fractionation (AF4), coupled with hydrodynamic size measurement and comprehensive liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis of each fraction. Concentration-size profiles were deconvoluted into 10 HDL and 8 LDL Gaussian subspecies. Molecular volume ratios were used to evaluate proposed particle models, providing evidence for the presence of s-HDL disk and …

Faculty Publications

Following a comprehensive review, the International Society of Sports Nutrition (ISSN) has developed an official position on the role of dietary antioxidants in exercise and sport. Antioxidants play a complex, context-dependent role in vivo; they can facilitate recovery from exercise but may also hinder training adaptations when consumed at supraphysiological doses. While endogenous antioxidant systems can effectively maintain redox balance, dietary sources, particularly whole foods, can help mitigate excessive oxidative stress following intense/heavy training or inadequate recovery. The influence of dietary antioxidants depend on timing, dosage, type, and individual factors. The ISSN’s official position encompasses the following: (1) Redox balance …

White Iii, Olivia Finnegan, Joshua Culverhouse, Anthony Holmes, Robert Glenn Weaver Med, Phd

Faculty Publications

Background:

Children and adolescents with intellectual and developmental disabilities (IDD) are at greater risk for obesity and poor obesogenic behaviors (e.g., physical activity, screen time, diet, sleep) than their typically developing counterparts. The Structured Days Hypothesis (SDH) suggests that in typically developing children and adolescents, obesogenic behaviors worsen during periods of reduced structure (e.g., weekend or summer vacation). However, children and adolescents with IDD have unique factors that may alter how structure (i.e., pre-planned, segmented, adult supervised, out-of-home programs) influences obesogenic behaviors. Therefore, the objective of this systematic review and meta-analysis is to examine obesogenic behaviors during periods of more …

The Promise Of Mindfulness-Based Interventions: A Stress-Reduction Strategy For Testicular Cancer Survivors' Health-Related Quality Of Life, Michael J. Rovito, Colin F. Mahony, Kamalie Thomas, Keith Brazendale, Ciaran Fairman Ph.D., Cscs, Cet

Faculty Publications

Background: Testicular cancer (TC) disproportionately affects younger men and carries unique psychosocial and physiological consequences that extend well beyond treatment. Despite favorable survival rates, TC survivors frequently report diminished health-related quality of life (HRQoL). These burdens are often compounded by masculinity-related identity disruptions, fear of recurrence, sexual dysfunction, and a lack of tailored psychosocial support. Existing interventions remain limited, with most programs focused on physical rehabilitation or early detection. Few address the multidimensional stressors that shape the TC survivorship experience.

Aims: This narrative review examines the literature on HRQoL among TC survivors and evaluates the potential of mindfulness-based interventions (MBIs) …

Dual-Task Effects On Spatiotemporal, Kinematic, And Kinetic Parameters And Their Variability During Running, Hsiang-Ling Teng, Jo Armour Smith, Will F.W. Wu

Physical Therapy Faculty Articles and Research

Background

Running in real-world environments often requires using cognitive resources simultaneously with the motor task (dual tasking, DT). Limited existing evidence suggests that DT reduces running speed. Movement variability is essential for a healthy, adaptable motor system. DT has been shown to affect movement variability during walking. Nonetheless, it remains unclear how DT affects spatiotemporal, kinematic, and kinetic parameters and their variability during running.

Research question

Does DT affect spatiotemporal, kinematic, and kinetic measures and their variability during running? Does running speed influence DT effects?

Methods

Thirty-one asymptomatic runners participated in this cross-sectional study. Three-dimensional running biomechanics were recorded while …
