Background: Warm-up is commonly recommended for injury prevention and performance enhancement across all activities, yet this recommendation is not supported by evidence for repetitive submaximal activities such as instrumental music performance.
Purpose: The objective of this study is to quantify the effects of cardiovascular, core muscle, and musical warm-ups on muscle activity levels, musical performance, and subjective experience in skilled violinists.
Methods: Fifty-five undergraduate, postgraduate, or professional violinists performed five randomly ordered 45-s musical excerpts of varying physical demands both before and after a randomly assigned 15-min, moderate-intensity cardiovascular, core muscle, musical (technical violin exercises), or inactive control warm-up protocol. Surface EMG data were obtained for 16 muscles of the trunk, shoulders, and right arm during each musical performance. Sound recording and perceived exertion (RPE) data were also obtained. Sound recordings were randomly ordered and rated for performance quality by blinded adjudicators. Questionnaire data regarding participant pain sites and fitness levels were used to stratify participants according to pain and fitness levels. Data were analyzed using two- and three-factor ANCOVA (surface EMG and sound recording) and Wilcoxon matched pairs tests (RPE).
Results: None of the three warm-up protocols had significant effects on muscle activity levels (P ≥ 0.10). Performance quality did not significantly increase (P ≥ 0.21). RPE significantly decreased (P < 0.05) after warm-up for each of the three experimental warm-ups; control condition RPE did not significantly decrease (P > 0.23).
Conclusion: Acute physiological and musical benefits from cardiovascular, core muscle, and musical warm-ups in skilled violinists are limited to decreases in RPE. This investigation provides data from the performing arts in support of sports medical evidence suggesting that warm-up only effectively enhances maximal strength and power performance.

The objective of this study is to gain insight into the current research frontiers, hotspots, and development trends in the field of immunization programs for women and children, and to provide scientific guidance and reference for follow-up research. Based on all the original research papers related to the research on immunization programs for women and children in the Web of Science Core Collection (WoSCC) database, bibliometric studies and visual analysis were carried out to explore the research frontiers, hotspots and development trends, and to analyze the risk factors affecting the vaccination coverage of immunization programs for women and children. Eight hundred forty-three papers obtained from 1,552 institutions in 96 countries/regions from January 1950 to August 2024, coauthored by 4,343 authors.

However, while PVS is also prevalent amongst Vascular Dementia (VD), the pathological distinctions between regional PVS in AD- and VD-driven cohorts remain largely unknown. Through a mixed dementia cohort, we examined these pathology-driven localization patterns via automated PVS segmentations from T2-weighted MRI.

Background: The location of proposed brain MRI markers of small vessel disease (SVD) might reflect their pathogenesis and may translate into differential associations with cognition. We derived regional MRI markers of SVD and studied: (i) associations with cognitive performance, (ii) patterns most likely to reflect underlying SVD, (iii) mediating effects on the relationships of age and cardiovascular disease (CVD) risk with cognition.
Method: In 891 participants from The Multi-Ethnic Study of Atherosclerosis, we segmented enlarged perivascular spaces (ePVS), white matter hyperintensities (WMH) and microbleeds (MBs) using deep learning-based algorithms, and calculated white matter (WM) microstructural integrity measures of fractional anisotropy (FA), trace (TR) and free water (FW) using automated DTI-processing pipelines.

Background: The higher prevalence and incidence of later life dementia among older Black Americans compared to older White Americans is incompletely understood and understudied. HATS is designed as a companion to the Mayo Clinic Study of Aging (MCSA) with a focus on identification of modifiable cardiovascular contributions to brain health among Black older adults living in urban areas in the upper Midwest.
Method: HATS is enrolling 300 U.
