A non-volitional skeletal muscle endurance test measures functional changes associated with impaired blood flow.

An electrically stimulated intermittent fatigue test using mechanomyography was recently proposed as a possible tool for detecting clinically relevant changes in muscle function. This study was designed to determine whether the proposed test can detect additional fatigue when it should be present. Subjects ( = 10) underwent two trials each (occluded and normal blood flow) with a standardized fatigue protocol on the Ankle Dorsiflexors (AD) and Wrist Extensors (WE) using a clinical electrical stimulator.

2021 Year in Review: E-Cigarettes, Hookah Use, and Vaping Lung Injuries During the COVID-19 Pandemic.

Electronic cigarettes (e-cigarettes) and hookah smoking have gained tremendous popularity over the past decade. With the constantly evolving e-cigarette market and potential impact of the COVID-19 pandemic on users of these tobacco products, research is needed to assess the prevalence and safety of these devices as well as potential public health implications and cessation tools. For this year in review, PubMed was searched from January 2021-December 14, 2021, for articles related to e-cigarettes, vaping-related lung injury, and hookah smoking.

A retrospective analysis of associations between BMI and days spent on mechanical ventilation in a level 1 trauma facility.

Objective: To examine whether BMI impacts the outcomes of mechanically ventilated patients.

Methods: Data was collected retrospectively among patients involved in motor vehicle accidents in intensive care at a major trauma center in Atlanta, GA. Patients were categorized into five BMI groups: underweight (BMI < 18.

Downhill Running Impairs Activation and Strength of the Elbow Flexors.

Brandenberger, KJ, Warren, GL, Ingalls, CP, Otis, JS, and Doyle, JA. Downhill running impairs activation and strength of the elbow flexors. J Strength Cond Res 35(8): 2145-2150, 2021-The purpose of this study was to determine if knee extensor injury induced by 1 hour of downhill running attenuated force production in the elbow flexors.
