Fig 1.
Mean power output during the three intervals under all four conditions.
* indicates P<0.05 in comparison to interval #1. NoNo: normoxia with normoxic recovery; NoHOX: normoxia with hyperoxic recovery; HoHo: hypoxia with hypoxic recovery; HoHOX: hypoxia with hyperoxic recovery.
Fig 2.
Changes in arterial oxygen saturation (SaO2) during the three intervals under all four conditions.
For clarity, the associated statistical analyses are documented in Table 2. NoNo: normoxia with normoxic recovery; NoHOX: normoxia with hyperoxic recovery; HoHo: hypoxia with hypoxic recovery; HoHOX: hypoxia with hyperoxic recovery.
Table 1.
The values (means ± SD) of the different metabolic and perceptual responses of the athletes (n = 10) during the 3x3-min DP intervals in association with the different oxygen contents during the intervals and recovery periods.
NoNo: normoxia with normoxic recovery; NoHOX: normoxia with hyperoxic recovery; HoHo: hypoxia with hypoxic recovery; HoHOX: hypoxia with hyperoxic recovery.
Table 2.
The values (means ± SD) of the EMG and the TSI responses of the athletes (n = 10) during the 3x3-min DP intervals in association with the different oxygen contents during the intervals and recovery periods.
NoNo: normoxia with normoxic recovery; NoHOX: normoxia with hyperoxic recovery; HoHo: hypoxia with hypoxic recovery; HoHOX: hypoxia with hyperoxic recovery.
Table 3.
The mean (± SD) absolute power outputs in watt of the athletes (n = 10) during the three 3-min intervals of DP while breathing air of different oxygen contents during the intervals of exercise and recovery periods.
NoNo: normoxia with normoxic recovery; NoHOX: normoxia with hyperoxic recovery; HoHo: hypoxia with hypoxic recovery; HoHOX: hypoxia with hyperoxic recovery.
