  Verification of Blood Lactate during Incremental Exercise Testing
  Author(s): Kazuyuki Kominami* and Masatoshi Akino
  
  Background:The increase in Blood Lactate (BLa) level during incremental exercise testing (Inc-Ex) leads to bicarbonate ion buffering and excretion of carbon dioxide (CO2). The relationship between the excretion of excess CO2 and BLa during Inc-Ex is unclear. This study aimed to verify whether BLa could be estimated from excess CO2 excretion during Inc-Ex. Methods: We recruited 11 patients (group P, age: 72.6 ± 8.5 years; male: 9) who were prescribed medication for cardiovascular risk factors or diseases. Twenty-two healthy participants (group H, age: 69.3 ± 6.7 years; male: 9) were also recruited for comparison. All participants performed the symptomatic limited cardiopulmonary exercise test, and their BLa levels were measured. Excess CO2 (the difference between oxygen uptake and CO.. View More»
