Pmax: maximal power; HRave; average heart rate during total training session; HR max: maximal heart rate during main part training session; SO₂: oxygen saturation during training session; RPE: Rated Perceived Exertion; EE: energy expenditure; AitH: Aerobic interval training Hypoxia group; AitN: Aerobic interval training Normoxia group; SitH: Sprint interval training Hypoxia group; SitN: Sprint interval training Normoxia group. P-values of analysis of variance to compare differences between groups at baseline.

^aIndicates differences with respect to AitN (post-hoc t-test with Bonferroni correction).

^bIndicates differences with respect to AitH (post-hoc t-test with Bonferroni correction).

^cIndicates differences with respect to SitN (post-hoc t-test with Bonferroni correction).

^dIndicates differences with respect to SitH (post-hoc t-test with Bonferroni correction).

Values in bold are significant.
