Table 1: Descriptive characteristics of the study subjects.

VariablesSubjects ( = 42)

Age (yr)20.7 ± 2.2
Height (cm)165.3 ± 7.9
Weight (kg)68.4 ± 11.7
VO2peak (mL·kg−1·min−1)26.4 ± 3.9
HRpeak (beats·min−1)182.3 ± 12.3
VO2@30 W (mL·kg−1·min−1)11.2 ± 2.2
HR@30 W (beats·min−1)80.9 ± 12.3
Systolic pressure at 30 W (mm Hg)119.0 ± 2.8
Diastolic pressure at 30 W (mm Hg)76.8 ± 2.2
Rate-pressure product at 30 W (bpm·mm Hg)9,445 ± 1,589

HRpeak: peak heart rate; VO2peak: peak oxygen consumption. HR@30 W: heart rate during exercise at the submaximal workload of 30 W; VO2@30 W: oxygen consumption during exercise at the submaximal workload of aerobic exercise. Systolic pressure, diastolic pressure, and rate-pressure product at 30 W = systolic blood pressure, diastolic blood pressure, and heart rate × systolic pressure product during exercise at the fixed workload of 30 W. Data are means ± standard deviations.
