The Role Of Reported Affective Symptoms And Anxiety In Recovery Trajectories After Sport-Related Concussion, Bernadette A. D'Alonzo, Abigail C. Bretzin, Douglas J. Wiebe, Ivy League–Big Ten Epidemiology Of Concussion Study Investigators, Arthur C. Maerlender, Cary R. Savage

Center for Brain, Biology, and Behavior: Faculty Publications

Background: There is growing awareness and clinical interest in athletes with affective symptoms after sport-related concussion (SRC), as these symptoms may contribute to overall symptoms and represent a modifiable risk factor of longer recovery. However, evidence of their effects on the entire return-to-play (RTP) trajectory, particularly among women and men, is limited.

Purpose/Hypothesis: To examine the relationship between affective symptom reporting and RTP progression after SRC among a cohort of Division 1 student-athletes. We hypothesized that those endorsing affective symptoms, specifically nervous-anxious symptoms, spend more time in RTP progression and recovery.

Study Design: Cohort study; Level of evidence, 3.

Methods: …

Mild Traumatic brain injury (mTBI) is a signature wound in military personnel, and repetitive mTBI has been linked to age-related neurogenerative disorders that affect white matter (WM) in the brain. However, findings of injury to specific WM tracts have been variable and inconsistent. This may be due to the heterogeneity of mechanisms, etiology, and comorbid disorders related to mTBI. Non-negative matrix factorization (NMF) is a data-driven approach that detects covarying patterns (components) within high-dimensional data. We applied NMF to diffusion imaging data from military Veterans with and without a self-reported TBI history. NMF identified 12 independent components derived from fractional …

Research outputs 2022 to 2026

Individuals at risk of Developmental Coordination Disorder (DCD) have low levels of physical activity in childhood due to impaired motor competence; however, physical activity levels in adulthood have not been established. This study sought to determine the impact of DCD risk on physical activity levels in adults using accelerometry measurement. Participants (n = 656) from the Arvo Ylppö Longitudinal Study cohort had their motor competence assessed at the age of five years, and their physical activity quantified via device assessment at the age of 25 years. Between group differences were assessed to differentiate physical activity measures for individuals based on …

The Reliability And Magnitude Of Time-Dependent Force-Time Characteristics During The Isometric Midthigh Pull Are Affected By Both Testing Protocol And Analysis Choices, Stuart N. Guppy, Yosuke Kotani, Claire J. Brady, Shannon Connolly, Paul Comfort, Gregory G. Haff

Research outputs 2022 to 2026

This study aimed to investigate whether the use of short-duration (SHORT) isometric midthigh pull (IMTP) trials resulted in greater reliability and magnitude of time-dependent force-time characteristics than traditionally performed IMTP trials (TRAD). Fourteen subjects with > 6 months' training experience with the power clean volunteered to take part in the study. Subjects performed five ∼1-second IMTP trials (SHORT) and five 5-second IMTP trials (TRAD). SHORT resulted in substantially more reliable rate of force development (RFD) measures (intraclass correlation coefficient [ICC] = 0.97–0.99; coefficient of variation [CV] = 2.6–7.0%), particularly during time bands from force-onset to 150 ms, compared with TRAD when …

Beta-Alanine Supplementation And Anaerobic Performance In Highly Trained Judo Athletes, Mateusz Halz, Magdalena Kaszuba, Jonatan Helbin, Sara Krzysztofik, Aleksandra Suchanecka, Adam Zając

Baltic Journal of Health and Physical Activity

Introduction. Previous studies have shown that several weeks of beta-alanine (BA) supplementation increases anaerobic work capacity and decreases muscular fatigue, but limited research was conducted on elite martial arts athletes. Therefore, the purpose of this study was to investigate the effect of chronic BA supplementation on high-intensity intermittent upper and lower-body performance in highly-trained judo athletes. Material and Methods: Sixteen elite judo athletes (21.8 ± 2.5 years old) were randomly assigned to receive either BA (4 g/d over the first 2 weeks and 6 g/d in the last 2 weeks) or placebo for 4 weeks. Before and after BA supplementation, …

The Effects Of A Carbohydrate Hydrogel Beverage On Gastrointestinal Symptoms And Running Performance In Comparison To Conventional Carbohydrate Beverages, Nicholas Minichiello

Masters Theses, 2020-current

PURPOSE: The utilization of hydrogel technology allows carbohydrate beverages to form a gel in the acidic environment of the stomach, potentially enhancing gastric emptying. However, few studies have researched the effects of these beverages on gastrointestinal (GI) tolerance and exercise performance; there is minimal data in a variety of exercise conditions and/or beverage ingestion rates. The purpose of the present study was to assess the effects of a 80 g/h of maltodextrin-fructose hydrogel (MF-H) beverage versus conventional carbohydrate sources on GI symptoms and running performance. METHODS: eight distance runners (26 ± 5 y; VO_2max = 65 ± 7 ml/kg/min) …

The Impact Of Sleep On Athletic Performance: A Review Of The Literature, Rylan J. Pratt

Honors Thesis

This paper reviewed the literature regarding sleep and athletic performance, specifically identifying the problem of sleep debt in student athletes, the effects of sleep debt, and what factors negatively influence sleep, along with how to improve sleep. The literature revealed that it is common for athletes to not get adequate sleep. Sleep debt can have psychomotor and physiological effects on the body, which decreases optimal athletic performance. The many factors that negatively impact sleep include high intensity training sessions, travel, sleep disturbances, caffeine and/or alcohol consumption, and pre-competition anxiety. Recommendations for athletes that are struggling to achieve adequate sleep include, …

Reliability And Utility Of A Lumbopelvic-Hip Complex Stability Assessment In Individuals With Patellofemoral Pain, Erika Zambarano, Neal Glaviano, Amanda Murray

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

OBJECTIVE
Lumbopelvic-hip complex (LPHC) stability is related to altered movement patterns that are present in individuals with PFP. Current studies measuring LPHC function in PFP primarily assess endurance and not stability. A test of isolated LPHC stability, the Seated Trunk Control Test (STCT) was recently developed and test-retest reliability for the STCT has been shown to be excellent in a healthy population. To improve the clinical usefulness of the STCT, we aimed to establish test-retest reliability for individuals with PFP. We hypothesized the STCT would show good-to-excellent reliability. We also compared STCT performance between healthy individuals and those with PFP. …

Establishing Safe Thresholds To Improve Exercise Capacity In Collegiate Athletes With Inflammatory Bowel Disease (Ibd): A Critically Appraised Topic, Emily C. Roberts, Jenny Toonstra, Andrea Cripps

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

CLINICAL SCENARIO
Crohn’s Disease (CD), Ulcerative Colitis (UC), and Indeterminate Colitis (IC) are forms of Inflammatory Bowel Disease (IBD), a complex auto-immune disorder of the GI tract. IBD can present several challenges to athletic participation due to unpredictable disease activity and uncontrollable systemic symptoms that severely impact daily activities and limit exercise/sports participation. Limited studies and a lack of standard guidelines for physical activity (PA) and exercise are additional barriers for patients. The limitation of studies and absence of standard guidelines are a particular concern for Athletic Trainers who may encounter collegiate athletes with IBD and must navigate the return-to-play …
