The Acute Hemodynamic Effects of Caffeine During Different Body Positions in Normotensive Young Adults
Revista De Chimie(2020)
摘要
The aim of this study was to investigate the acute cardiovascular hemodynamic effects of administration of a fixed dose of 130 mg of caffeine versus placebo in a sample of healthy young adults (N = 32, sex ratio 1/1), who were successively placed in four distinct positions (orthostatic before ingestion, orthostatic, supine and Trendelenburg vertical positions, after ingestion) on a gravitational inversion table. The experimental design was a single-center, parallel-group, double-blind, randomized, placebo-controlled clinical trial. Following the descriptive and inferential statistical processing of the data, a statistical significant pattern (p [0.05) of acute postural cardiovascular hemodynamic adaptation of the subjects was revealed, under the influence of caffeine versus placebo ingestion.
