The results for the HRmax and VO2max are presented in Table 1. There was a significant lower HRmax value in the protocol in water (SRW) compared to the two protocols on land (TRE, SRL) [F(2,7) = 36.128, p < 0.001]. For the VO2max, the results showed significant greater values for the treadmill protocol when compared to the two stationary running protocols [F(2,7) = 14.121, p = 0.004]. In addition, between the SRW and SRL no significant differences were found. The eta2 for HRmax and VO2max was 0.84 and 0.64 in the protocols factor, respectively.
