Cardiac variables in the Doppler test

	Trials	Rest	Exercise	Recovery
HR (beats/min)	60EX	70.0 ± 2.8	104.5 ± 4.1^*	78.0 ± 4.2^*
HR (beats/min)	80EX	71.2 ± 1.4	105.5 ± 3.1^†	79.0 ± 3.7^†
SV (mL)	60EX	83.0 ± 4.1	106.6 ± 6.9^*	100.2 ± 5.9^*
SV (mL)	80EX	81.5 ± 4.6	114.6 ± 7.4^†^§	100.8 ± 3.9^†
CO (L/min)	60EX	5.9 ± 0.2	11.5 ± 0.6^*	7.7 ± 0.3^*
CO (L/min)	80EX	5.8 ± 0.3	12.3 ± 0.6^†^§	7.9 ± 0.3^†

Values are mean ± SE (n = 5). Values are averaged over the last 30 sec of each session. HR, heart rate; SV, stroke volume; CO, cardiac output. SV and CO were obtained by the Doppler echocardiography. *P < 0.05 vs. at Rest in the 60EX trial. ^†P < 0.05 vs. at Rest in the 80EX trial. ^§P < 0.05 60EX trial vs. 80EX trial.
