Low Energy Availability (Lea) And Its Relationship To Nutritional Status And Bone Health In Collegiate Athletes, Anthony Dempsey

UNH URC Open (2026 and after)

This project aims to identify low energy availability in a sample of collegiate athletes and explore the relationship with bone mineral density and nutrient deficiencies. Participants (n=3,407) were recruited from a northeast university and self-reported athlete status and physical activity via online questionnaire. Food records were used to calculate energy and nutrient intake. Anthropometrics including height, weight, body composition and bone mineral status were measured in duplicate. Energy availability (EA) was calculated as (Energy Intake (EI) -Exercising Energy Expenditure) (EEE)) /Fat Free Mass (FFM) (kg) and categorized as optimal (>45 kcal/kg FFM), subclinical, or clinically low (< 30 kcal/kg FFM). Fifteen percent of participants were characterized as athletes (club or division I varsity); mean EA was lower among athletes vs. nonathletes (17.90.7vs.21.90.3, p< .001). Males were more likely to have optimal EA status vs. females (8.8vs4.7%, p< .001). Most females (75.1%) were categorized as clinically LEA; 20.3% had subclinical LEA. Among men, athletes’ EA was similar to nonathletes (21.11.2vs22.20.5, p=.4); among females, athletes had lower EA vs. nonathletes (16.220.9vs21.70.3, p< .001). Males with clinically low EA were most likely to consume inadequate intakes of potassium, fiber, iron, and vitamin D (77.1,94.0,10.4 and 97.3%, respectively); similarly, females with clinically low EA, were most likely to consume inadequate intakes (81.9,87.6,88.3, and 99.5%, respectively). Bone z-scores were higher among athletes vs. non athletes (-.27±.06vs-.67±.02, p< .001) but were not different by EA status. Given the prevalence of LEA within the college athlete and nonathlete populations, further research and tailored nutritional education is needed for this at-risk population.

Human Movement Studies & Special Education Faculty Publications

Background: Favorable attitudes toward regular leisure-time physical activity may not always translate into intention if adolescents feel ambivalent about the behavior. This study tested whether felt ambivalence weakens the prospective attitude–intention association and the indirect effect of attitude on later behavior through intention. Methods: Chinese adolescents (N = 1714; Grades 7–12; mean age = 15.0 years) completed a three-wave survey at approximately two-week intervals. Wave 1 assessed attitudes toward regular leisure-time moderate-to-vigorous physical activity, felt ambivalence, and physical activity habit; Wave 2 assessed intention; and Wave 3 assessed leisure-time physical activity. Moderated mediation was tested in a structural equation model …

From Intention To Enactment: Action Planning And Habit Automaticity Distinguish Successful From Unsuccessful Intenders To Engage In Regular Leisure-Time Moderate-To-Vigorous Physical Activity, Yaogang Han, Yubing Wang, Pan Li, Binn Zhang

Human Movement Studies & Special Education Faculty Publications

University students often intend to exercise regularly but fail to translate intention into action. The present study tested which post-intentional processes distinguish successful from unsuccessful intenders in self-reported regular leisure-time moderate-to-vigorous physical activity (MVPA) enactment. Chinese undergraduates from 10 universities completed a three-wave survey administered at roughly two-week intervals. Habit automaticity was assessed at Wave 1, intention together with action planning and coping planning at Wave 2, and self-reported regular-exercise status at Wave 3. Because the dependent variable was assessed using a single stage-based self-report item, the findings should be interpreted as explaining self-reported regular-exercise status rather than objectively measured …

The Relationship Between Physical Activity, Sleep, And Hallucinations In Adults With Charles Bonnet Syndrome, Jarrod Hollis, Rohit Narayan, Eldre W. Beukes, Rosie Lindsay, Aliyah Bharwani, Umair Mughal, Ikra Yaqoob, Justin A. Haegele, Scott Muriden, Peter M. Allen

Human Movement Studies & Special Education Faculty Publications

Physical activity levels, hallucination experiences, sleep quality, and perceived stress were assessed using a survey administered to 57 adults with a confirmed diagnosis of Charles Bonnet Syndrome (CBS). Physical activity demonstrated a significant negative correlation with hallucination severity (r = –0.335, p = 0.011, two-tailed). A significant negative correlation was also observed between physical activity and perceived stress (r = –0.497, p < 0.001, two-tailed). In contrast, no significant association was identified between hallucination frequency and sleep disruption or insomnia. These findings suggest that engaging in appropriate levels of physical activity may help reduce the severity of hallucinations and mitigate stress among individuals with CBS. The observation that higher levels of physical activity are associated with reduced hallucination burden may help the development of evidence-based management strategies for CBS. Additionally, the finding that physical activity was significantly related to hallucination severity, whereas sleep disruption was not, merits deeper exploration in future research.

Employing a scenario-based experimental design with a sample of 430 Chinese consumers, we explored price differences interact with loyalty status, price trajectory information, and brand consistency. Our findings reveal a complex non-linear inverse sigmoid relationship between rate disparity and channel switching. Contrary to expectations, loyalty membership did not reduce switching intent or increase discount thresholds. Moreover, rate disparity triggered brand integrity concerns, with brand doubt consistently exceeding switching intent. While price trajectory information did not change switching likelihood, …

Decreased Exercise-Induced Pulmonary Capillary Recruitment In Pulmonary Arterial Hypertension, David Langleben, Stylianos E. Orfanos, Benjamin D. Fox, Michele Giovinazzo, Magali Kaddis, John D. Catravas

Bioelectrics Publications

The human lung normally accommodates exercise-induced cardiac output increases mainly via recruitment of non-concomitantly perfused pulmonary capillaries. Recruitment is detectable by measuring the first-pass transpulmonary metabolism of ³H-benzoyl-Phe-Ala-Pro, providing an estimate of functional capillary surface area (FCSA). Pulmonary arterial hypertension (PAH) results from luminal narrowing of small precapillary arterioles, reducing downstream perfused FCSA. We hypothesized that exercising PAH patients would not be able to recruit FCSA normally. We studied two patients with severe PAH. Despite exercising to maximal dyspnea, neither could recruit FCSA. These limited data are the first direct measurements of FCSA in exercising PAH patients.
