Cardiovascular response and rate of perceived exertion a HR during hyperoxic exercise. *T1 is significantly lower than T2–6. T6 is significantly higher than T1, T3, and T4 (p < 0.05). b Systolic blood pressure during hyperoxic exercise. *T1 is significantly lower than T2, T3 and T6 (p < 0.05). c Diastolic blood pressure during hyperoxic exercise. No significant changes (p < 0.05). d Mean arterial blood pressure during hyperoxic exercise. No significant changes (p < 0.05). e Rate pressure product during hyperoxic exercise. *T1 is significantly lower than T2–6. T6 is significantly higher than T1 and T3 (p < 0.05). f Rate of perceived exertion (Borg score) during hyperoxic exercise. *T1 is significantly lower T2–T6 (p < 0.05)
