Pub Date : 2023-10-15 Sebastian Vetter, Pierre Hepp, Axel Schleichardt, Stefan Schleifenbaum, Maren Witt, Christian Roth, Hans-Peter Koehler
Strengthening the rotator cuff muscles is important for injury prevention and rehabilitation. However, there is considerable evidence that range of motion and fascicle length are risk factors for injury. Since muscle fascicle length improves motor performance and reduces the risk of injury, it may be an important variable to promote multidirectional changes in the function and macroscopic structure

Pub Date : 2023-07-08 Ferenc Torma, Csaba Kerepesi, Matyas Jokai, Peter Bakonyi, Erika Koltai, Gergely Babszki, Balazs Ligeti, Regina Kalcsevszki, Kristen M McGreevy, Steve Horvath, Zsolt Radak
Epigenetic clocks can measure aging and predict the incidence of diseases and mortality. Higher levels of physical fitness are associated with a slower aging process and a healthier lifespan. Microbiome alterations occur in various diseases and during the aging process, yet their relation to epigenetic clocks is not explored. To fill this gap, we collected metagenomic, epigenetic, and exercise-related

A comparison of critical speed and critical power in runners using Stryd running power medRxiv. Sports Med. Pub Date : 2023-07-06 Cody R van Rassel, Kate M Sales, Oluwatimilehin O Ajayi, Koki Nagai, Martin J MacInnis
Abstract Purpose: Although running traditionally relies on critical speed (CS) as an indicator of critical intensity, portable inertial measurement units (IMUs) offer a potential solution for estimating running mechanical power to assess critical power (CP) in runners. The purpose of this study was to determine whether CS and CP differ when assessed using the Stryd device, a portable IMU, and if two

Surveying Argentine healthcare providers' knowledge, attitude, and practice about diagnosis and management of sports-related concussions. medRxiv. Sports Med. Pub Date : 2023-06-27 Maria Julieta Russo, Fernando Salvat, Agostina Kanevsky, Marcelo Saco, Ignacio Alonso Hidalgo, Franco Della Vedova, Ricardo Allegri, Gustavo Sevlever
Background: A better understanding of the healthcare provider's knowledge, attitude, and practice (KAP) level would help athletes, trainers, and athletic administrators, implement more effective concussion-management recommendations and guidelines. This survey aims to understand healthcare provider's KAP dimensions regarding the diagnosis and management of sports-related concussions. Methods: Cross-sectional

Concussion acutely disrupts auditory processing in Division I football student-athletes medRxiv. Sports Med. Pub Date : 2023-06-22 Jennifer Krizman, Danielle Colegrove, Jenna Cunningham, Silvia Bonacina, Trent Nicol, Matt Nerrie, Nina Kraus
Diagnosis, assessment, and management of sports-related concussion requires a multi-modal approach. Yet, currently, an objective assessment of auditory processing is not included. The auditory system is uniquely complex, relying on exquisite temporal precision to integrate signals across many synapses, connected by long axons. Given this complexity and precision, together with the fact that axons are

Dose response of running on blood biomarkers of wellness in the generally healthy medRxiv. Sports Med. Pub Date : 2023-06-04 Bartek Nogal, Svetlana Vinogradova, Milena Jorge, Ali Torkamani, Paul Fabian, Gil Blander
Exercise is effective toward delaying or preventing chronic disease, with a large body of evidence supporting its effectiveness. However, less is known about the specific healthspan-promoting effects of exercise on blood biomarkers in the disease-free population. In this work, we examine 23,237 generally healthy individuals who self-report varying weekly running volumes and compare them to 4,428 generally

The effects of a dietary supplement on brain function and structure in Junior A ice hockey players: a prospective randomized trial medRxiv. Sports Med. Pub Date : 2023-05-25 Logan T. Breuer, Shaun D. Fickling, David A. Krause, Ryan C.N. D’Arcy, Tory O. Frizzell, Tania Gendron, Michael J. Stuart
Background Neurocognitive impairment linked to head impact exposure in otherwise healthy, non-concussed athletes may be associated with adverse long-term outcomes. The primary purpose of this study was to evaluate whether a dietary supplement, SynaquellTM, supports brain function and structure in male Junior A ice hockey players over the course of a season.

The Role of Oestrogen in Female Skeletal Muscle Ageing: A Systematic Review medRxiv. Sports Med. Pub Date : 2023-05-23 Annabel J. Critchlow, Danielle Hiam, Ross Williams, David Scott, Séverine Lamon
Ageing is associated with a loss of skeletal muscle mass and function that negatively impacts the independence and quality of life of older individuals. Females demonstrate a distinct pattern of muscle ageing compared to males, potentially due to menopause where endogenous sex hormone production declines. This systematic review aims to investigate the current knowledge about the role of oestrogen in
