- ND= normal diet.
- 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 ergometer 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).
- POSTdiet vs. Stage1–4 *= p<0.05; **= p<0.01; ***= p<0.001.
