LPVD= low-protein vegetarian diet. PREdiet= a fasting blood sample taken in the morning before the start of ND or LPVD (day 1). POSTdiet= a fasting blood sample taken in the morning after a 4-day ND or LPVD (day 5). PREtest= a resting blood sample taken 30 min after a breakfast, before the cycle ergometre test (day 5). Stage1–4= blood samples

taken after 10-min cycling at 40, 60 and 80% of VO2max and after the maximal stage (at 100% of VO2max until exhaustion). PREdiet compared to POSTdiet #= p<0.05. POSTdiet vs. Stage 1–4 *= p<0.05; **= p<0.01; ***= p<0.001. Selleckchem Compound Library There were no differences in serum albumin between the diet groups at rest or during cycling. Within LPVD group, albumin increased from 39.4 ± 3.1 g/l (PREdiet) to 41.7 ± 2.0

g/l (POSTdiet) (p=0.032). Within each diet group, cycling caused some statistically significant changes, which are presented in Table  6. Discussion Main results The main result of this study was that there was no difference in venous blood acid–base status and its independent or dependent variables between a 4-day LPVD and ND. However, one statistically significant change in acid–base status did occur in the LPVD group, as SID increased by 3.1% over the 4-day diet period. During cycling, the diet composition caused some differences in aerobic energy production, which could be seen in significantly higher VO2 and VCO2 at every submaximal Quinapyramine workload after LPVD compared to ND. The PRAL value of every foodstuff MK 8931 cost consumed in LPVD was under 0, so the diet was clearly designed to enhance the production of alkali in the body.
