摘要: The purpose of this investigation was to examine the effect ammonium chloride (NH4Cl) and sodium bicarbonate (NaHCO3) ingestion on physical working capacity at fatigue threshold (PWCFT). Eighteen adult males (mean age, SD=23, 2 years) volunteered for two experiments (experiment 1,n=9 ; experiment 2,n=9). In both experiments, subjects orally ingested 0.3 g · kg−1 body weight NH4Cl NaHCO3 over a 3-h period in random order days separated by 72 h or more. 1, following substance, performed discontinuous incremental cycle ergometer test onset PWCFT which estimated from integrated electromyography voltages vastus lateralis muscle. 2, continuous test. results these indicated that had no significant (P>0.05) 1: NH4Cl=257, SD 26 W; NaHCO3=256, 22 W;t=0.06;r=0.866; 2: NH4Cl=231, 14 NaHCO3=216, 16 W;t=1.78;r=0.857).
