Table 1 shows HR, VO2, VCO2, and VE values at rest before CSW and BJS tests. Statistics did not
highlight any difference between the two settings, thus athletes started tests from similar conditions.
Figure 2 shows parameter values which reached statistical significance. In particular, the upper panel
demonstrates that workload at AT was significantly increased by beetroot juice supplementation as
compared to the CSW test. In detail, workload reached at AT was 6.3 ± 1.0 and 6.7 ± 1.1 kg during the
CSW and the BJS test respectively. The lower panel of Figure 2 also demonstrates that AEC was
significantly reduced during the BJS test, as this parameter reached a level of 1.9 ± 0.5 during the
CSW test and 1.7 ± 0.3 kcal·kg−1·h−1 during the BJS test. None of the other variables measured at
anaerobic threshold (i.e., VO2, VCO2, VE, and HR) were significantly affected by beetroot juice
supplementation, as shown by Table 2. The kg level at maximum workload was effected but not at a
significant value. It is likely that increasing the number of participants would have resulted in a
statistically significant outcome.
