LPVD= low-protein vegetarian diet. The values of VO2, VCO2, VE and RQ are presented in Table 5. After LPVD, VO2 was significantly higher at 40, 60 and 80% of VO2max (2.03 ± 0.25 vs. 1.82 ± 0.21 l/min, p=0.035; 2.86 ± 0.36 vs. 2.52 ± 0.33 l/min, p<0.001 and 4.03 ± 0.50 vs. 3.54 ± 0.58 l/min, p<0.001; respectively), but not at 100% of VO2max, compared to ND (Figure 2). Also, VCO2 differed significantly at all submaximal stages, being higher after LPVD (p=0.011. p=0.009, p=0.010, respectively). VE tended to be higher at all stages after LPVD,
but the difference was significant (p=0.009) only at Stage 2. RQ was not different between the diet groups at any point of the cycling.

However, none of the VO2max values differed significantly from each other. Blood carbohydrate and fat metabolites and serum albumin There were no differences in venous blood lactate, glucose, FFA or TG between the two diet groups at rest or during cycling. At rest, TG decreased significantly (p=0.021) during LPVD (PREdiet vs. POSTdiet). During cycling there were, within each diet group, some statistically significant changes that are presented in Table 6.
