Effects of caffeine ingestion on physiological indexes of human neuromuscular fatigue: A systematic review and meta‐analysis

Abstract

Background: Caffeine is often used as a stimulant during fatigue, but the standard of characteristic physiological indicators of the effect of caffeine on neuromuscular fatigue has not been unified. The purpose of this systematic review and meta-analysis is to summarize current experimental findings on the effects of caffeine on physiological indexes before and after neuromuscular fatigue, identify some characteristic neuromuscular physiological indexes to assess the potential effects of caffeine. Methods:The Preferred Reporting Items for Systematic Reviews and Meta-analyses are followed. We systematically searched PubMed, Google academic, and Web of Science for randomized controlled trials. We searched for studies on caffeine's (i) effects on neuromuscular fatigue and (ii) the influence of physiological indexes changes. Metaanalysis was performed for standardized mean differences (SMD) between caffeine and placebo trials in individual studies. Results:The meta-analysis indicated that caffeine significantly improves voluntary activation (VA) (

The medicinal value of tea drinking in the management of COVID-19

“…And green tea polyphenol ornament preparation with EGCG as the major constituent, has been approved by the Food and Drug Administration (FDA) [ 7 ]. The alkaloids in tea show multiple functions such as activating the nerve center, protecting liver cells, and affecting the respiratory system, and are widely used in health care products and medicines [ 8 ]. Tea also contains a variety of amino acid components, of which l -theanine is a unique amino acid in tea (a non-protein amino acid).…”
