An Evidence-Based Review Of The Pathophysiology, Treatment, And Prevention Of Exercise-Associated Muscle Cramps, Kevin C. Miller, Brendon P. Mcdermott, Susan W. Yeargin, Aidan Fiol, Martin P. Schwellnus

Faculty Publications

Exercise-associated muscle cramps (EAMCs) are common and frustrating for athletes and the physically active. We critically appraised the EAMC literature to provide evidence based treatment and prevention recommendations. Although the pathophysiology of EAMCs appears controversial, recent evidence suggests that EAMCs are due to a confluence of unique intrinsic and extrinsic factors rather than a singular cause. The treatment of acute EAMCs continues to include self-applied or clinician-guided gentle static stretching until symptoms abate. Once the painful EAMCs are alleviated, the clinician can continue treatment on the sidelines by focusing on patient-specific risk factors that may have contributed to the onset …

Non-Steroidal Anti-Inflammatory Drugs On Core Body Temperature During Exercise: A Systematic Review, Dawn M. Emerson, Stephen Cl Chen, Melani R. Kelly, Bryant Parnell, Toni M. Torres-Mcgehee

Faculty Publications

BACKGROUND: Because of their anti-pyretic effects, some individuals prophylactically use non-steroidal anti-inflammatory drugs (NSAIDs) to blunt core temperature (Tc) increases during exercise, thus, potentially improving performance by preventing hyperthermia and/or exertional heat illness. However, NSAIDs induce gastrointestinal damage, alter renal function, and decrease cardiovascular function, which could compromise thermoregulation and increase Tc. The aim of this systematic review was to evaluate the effects of NSAIDs on Tc in exercising, adult humans. METHODS: We conducted searches in MEDLINE, PubMed, Cochrane Reviews, and Google Scholar for literature published up to November 2020. We conducted a quality assessment review using the Physiotherapy Evidence …
