The Effects of Different Volume-Load on Sprint and Change of Direction Performance
Get PDFThis study was designed to compare the effects of two different strength training protocols on sprint and change of direction (COD) performance in recreationally trained athletes. Participants were evaluated on maximal dynamic (1RM squat) and isometric (IMTP) strength, speed (30m sprint), and COD (5-0-5 test). The participants were divided into two groups (Low volume-heavy load group [LV], High volume-moderate load high-intensity endurance (HIE) group [HV]) after initial testing, for a 4-week training intervention using traditional and weightlifting derivative lifts. The training consisted of 5 sessions per week (3 sessions resistance training [RT], each about 40-50 mins; 2 sessions sprint & COD, each about 30 mins), after the 4-week intervention, participants were retested. Data was analyzed using repeated measures ANOVA, and effect sizes were calculated using Cohen’s d. The study showed moderate improvement in sprint performance for both groups (d=0.577, p=0.0015) with no difference between the two. HV had a statistically significant improvement in 1RM (d= 1.065, p=0.01), but both LV and HV exhibited statistically significant improvement in relative strength (respectively [SREL], d=-1.27, -2.528; p=0.004, \u3c 0.0001). COD performance and IMTP peak force (PF) was marginally improved in either group. Concurrently, sprint and resistance training is recommended to improve sprint performance. However, COD does not appear to be affected in the same fashion by relative strength and may have a greater learning adaptation for recreationally trained athletes compared to sprinting

Frontal sinus mucocele in a 79-year-old with ptosis
No full textA mucocele is a benign, mucus-filled cystic lesion that can occur when paranasal sinus drainage is obstructed. As mucoceles grow, they may cause erosion of the bony sinus walls and symptoms of mass effect, such as nasal congestion, headaches, and proptosis. Uncommonly, they can expand into the orbit and present with ptosis due to compression of Cranial Nerve III (oculomotor nerve). This case report describes a 79-year-old male who first presented to the ophthalmology clinic with a 6-12 month history of unilateral ptosis. On exam, right-sided eyelid ptosis with mild restriction on right upward gaze was noted. Past ophthalmic history is significant for cataracts, posterior vitreous detachment, nonexudative age-related macular degeneration, and presbyopia. There was no history of ocular injury or surgery. Imaging with MRI and CT revealed a right frontal sinus mucocele with sinus expansion encroaching on the right superior orbit with extension into the orbit. Multifocal sites of bone thinning surrounding the frontal sinus, and inferiorly displaced right globe proptosis due to mucocele extension were present. CT sinus imaging from 6 years prior was significant for pansinusitis and new mild polypoid mucosal thickening in the right frontal sinus. The patient was referred to ENT for surgical intervention. This case report chronicles the progression of mucocele development, including physical exam and imaging findings, following the unusual presentation of unilateral ptosis due to compression of Cranial Nerve III from mucocele expansion
Exploring Collaborations between Public Health and Healthcare in Rural Communities: Strengths and Barriers
No full textPURPOSE: Due to their similar missions and the limited availability of resources in rural settings, local health departments (LHDs) and healthcare organizations may be primed for collaboration. LHDs and healthcare organizations may partner for various reasons, but these collaborations are often limited in capacity and related to the completion of needs assessments There is also a gap in the literature in that most collaborations studied have not been located in rural communities and occurred before the COVID-19 pandemic. The purpose of this study is to explore the potential benefits of collaborations between LHDs and local healthcare organizations in rural communities, as well as the facilitators and barriers. METHODS: This qualitative study uses semi-structured interviews via Zoom to describe potential experiences, benefits, challenges, and strategies of these collaborations. Interviews were first conducted with participants from national or state organizations that represent or support LHDs and local healthcare organizations, followed by interviews with LHDs and local healthcare organizations located in or serving rural communities. Interview transcripts will be analyzed using a rapid-coding process to identify key themes. RESULTS: Analysis is ongoing, but preliminary results from the first stage of interviews indicate possible common reasons for collaborations in rural areas are related to the completion of needs assessments, emergency preparedness, and the sharing of funding and resources. Possible barriers to collaboration include perceived competition for funding and resources, including workforce. Trust and relationships between collaborating entities were deemed important facilitators. DISCUSSION: Study findings could provide rural LHDs and local healthcare organizations with tools to build and strengthen collaborations, as well as make the most of limited resources
Foggy with a Chance of Vibration: Exploring Light, Sound, and Spatial Perception in Multisensory Experience Design
No full textThe perception of a space that we feel, hear, and see emerges from the interplay of our senses rather than solely from its physical structure. This study investigates how artificial fog, sound, vibrations, and visuals shape depth perception, emotional engagement, and movement, offering insights into how sensory manipulation can transform spatial experiences. Understanding these interactions may inform the design of immersive environments, influencing how people interpret and navigate spaces both digitally and physically. By analyzing installations such as Karolina Halatek’s fog-based light sculptures in Metz, France, and teamLab’s interactive projection environments in Tokyo, Japan, this research explores how 3D soundscapes, fog density, and low-frequency vibrations impact spatial awareness and user perception. To test these effects, computer simulations in Unreal Engine 5 were conducted to examine how controlled sensory conditions influence perception. Results indicate that artificial fog alters depth perception, making spaces appear, larger, smaller, or stretched depending on density and lighting. Low-frequency vibrations generate tactile sensations from a distance, allowing sound to be felt rather than just heard, influencing interaction and movement. The synchronization of sound and visuals enhances emotional engagement, memory retention, and spatial awareness, reinforcing immersion and user presence. These findings have broad applications in Augmented Reality (AR), educational settings, interactive art, museum exhibitions, therapeutic environments, urban design, Virtual Reality (VR), and more. As these technologies evolve, the ability to fine-tune environmental stimuli will redefine immersive storytelling, interactive media, and spatial perception. Therefore, if we can manipulate perception, we can redefine reality—transforming how we experience art, space, and technology in ways once thought impossible
Evaluating Appalachian Farmacy: A Qualitative Process Evaluation of a Rural Produce Prescription Program
No full textIntroduction: Food insecurity remains a critical public health concern, particularly in rural, low-income communities. Produce prescription programs have emerged as a strategy to improve food access and promote healthier eating behaviors. This study presents a qualitative process evaluation of Appalachian Farmacy, a produce prescription program in Northeast Tennessee designed to increase fruit and vegetable consumption among individuals receiving Medicaid, Medicare, or Supplemental Nutrition Assistance Program (SNAP) benefits. Methods: Semi-structured interviews were conducted with program participants to explore their experiences, perceptions of the program, and barriers to participation. Transcripts were analyzed using rapid coding in Microsoft Excel to identify common themes. Results: Themes that emerged included inconsistent treatment and rules across grocery store locations, easy experiences for exchanging vouchers at farmer’s markets, desired changes for smaller voucher increments, barriers to attending educational events, suggestions for additional education topics, expanding sites and times for voucher accessibility, knowledge gained from educational classes, financial relief, increased socialization, overall health benefits, emotional and mental health benefits, changes in eating behaviors, improved access to fruits and veggies, increased variety of produce intake, and desired program expansion. Conclusion: These findings suggest that increasing accessibility—through expanded distribution sites, flexible voucher options, and enhanced educational support—could strengthen the program’s impact. Addressing these gaps can help optimize produce prescription programs as an effective strategy to combat food insecurity and promote healthier eating habits in rural communities
Characteristics of People Who Achieve Acceptable Symptom State after Total Hip Replacement
No full textPurpose: Patient Acceptable Symptom State (PASS) is characterized as the highest level of symptom state beyond which patients consider themselves well and achieve the desired functional status. The Joint Replacement version of the Hip Disability and Osteoarthritis Outcome Score (HOOS-JR) is used to assess the outcomes of total hip replacement (THR) in the USA. This study examined the characteristics of people who do or do not achieve PASS as reflected on HOOS-JR scores 6-months after THR. Methods: Data for people who underwent THR at a tertiary care hospital were extracted from clinical charts. The HOOS-JR scores at pre-surgery and 6-months after THR were extracted from the charts. People with HOOS-JR scores of \u3e76.7 at 6-months after THR were considered responders (achieved PASS), and those ≤76.7 were considered non-responders (did not achieve PASS). A multivariate binary logistic regression assessed the relationships between demographic and health variables, LBP, and pre-surgery HOOS-JR scores as independent variables and responder or non-responder as the dependent variable. The odds ratio (OR) was interpreted as the index of association, where OR with p values of \u3c0.05 were considered significant. Results: Twenty-four patients (37.5%) from the sample failed to achieve PASS at 6-months after THR. Logistic regression analysis identified higher BMI (OR=1.16, 95% confidence interval [CI]=1.01-1.34; P=0.03) and lower pre-surgery HOOS-JR scores (OR=1.06, 95% CI=1.01-1.10; P=0.01) were found to be significantly associated with achieving PASS for HOOS-JR at 6-months after THR. Conclusions: This study\u27s results indicate that people with higher BMI or lower pre-surgery HOOS-JR may not achieve optimal functional status at 6-months after THR. Physical therapists can provide interventions to improve lower extremity function in people scheduled to undergo THR to enable patients to experience timely recovery in hip function after THR
How does self-disclosure differ between those caring for individuals with Alzheimer’s disease and related dementias (ADRD) versus non-ADRD caregivers?
No full textIntroduction: Unpaid caregivers often juggle professional careers and academic responsibilities while caring for a loved one. This added responsibility can lead to heightened stress and an increased caregiver burden, particularly among ADRD caregivers. Caregiver-friendly workplaces and university environments can encourage individuals to disclose their caregiving responsibilities and obtain support. However, research to date is limited in this area. This study examines differences in self-disclosure between those caring for individuals with ADRD versus non-ADRD caregivers in a university setting. Methodology: A cross-sectional study compared the self-disclosure status of university employee and student caregivers (n=349) who provided unpaid care to an adult \u3e18 years. Participants completed a Qualtrics survey that assessed demographic information, caregiving context, and care recipient characteristics. Participants also completed the Zarit Burden Index. Differences between ADRD and non-ADRD caregivers were assessed using t-tests and chi square analyses. Results: Compared to non-ADRD caregivers, ADRD caregivers had fewer years of caregiving experience (3.79 ±4.78 vs. 5.54 ±6.90, p\u3c0.05) and were significantly more likely to provide personal care (79.01% vs. 52.34%, p\u3c0.0001) and provide support to older recipients (80.28 ±8.28 vs. 61.55 ±22.86 years, p\u3c0.001) with a greater number of health conditions (2.73 ±2.36 vs. 2.13 ±1.94, p=0.04). ADRD caregivers reported more paid (47.56% vs. 22.31%, p\u3c0.001) and unpaid (82.14% vs. 62.65%, p\u3c0.001) help compared to non-ADRD caregivers; however, they also experienced higher caregiver burden (19.59 ±10.69 vs. 16.53 ±9.96, p=0 .02). Despite receiving more support, ADRD caregivers were significantly more likely to disclose their caregiving role to university personnel and peers compared to non-ADRD caregivers (68.67% vs. 51.92%, p\u3c0.001). Implications: Findings highlight the self-disclosure behaviors of university employee and student caregivers, and the specific challenges faced by ADRD caregivers. Universities can provide additional support for employee and student caregivers to help them manage their professional, academic, and caregiving responsibilities.
