Abstract

INTRODUCTION: Skeletal muscle discomfort commonly occurs during long-distance air travel. Although the effects of high altitude on muscle have been well-studied, the effects of short-term exposure to the altitude at which aircraft cabins are pressurized, 2438 m, have not. The primary aim of this study was to examine global gene expression in the gastrocnemius muscle after simulated flight. Inflammatory indicators were also assessed in the muscle. METHODS: Thirty-five mice were evenly exposed to normobaria or hypobaria (2438 m) for -8-9 h. Microarray and ribonucleic acid (RNA) analyses were performed. Additionally, macrophage and neutrophil presence was examined. RESULTS: Fourteen genes were ..
