Physiological Results
The one-way repeated ANOVA revealed a significant main effect of time on SpO2 [F (3, 51) =111.21, p < 0.001, ηp2 =0.87]. Post hoc comparisons demonstrated that SpO2 in Test 2 was significantly lower than that in the other tests. The main effect of time was significant for HR [F (3, 51) =8.80, p < 0.001, ηp2 =0.34], with higher HR for Test 2 than the other tests. The main effect of time on SBP was significant [F(3, 51) =7.49, p < 0.001, ηp2 =0.31], and SBP was significantly higher in Test 2 than in Test 3. A significant main effect of time was found for DBP [F (3, 51) =26.75,p < 0.001, ηp2=0.61], with larger DBP in Test 2 than in the other tests. There was a main effect of time in VC [F (3, 51) =13.08, p < 0.001, ηp2 =0.44], with a smaller VC in Test 2 than in the other tests (Table 1).
