The purpose of this study was to compare the hemodynamic, arterial stiffness, and blood flow changes following four weeks of either continuous or discontinuous aerobic exercise in adults. Forty-seven subjects between the ages of 18 and 57 were recruited for one month of either continuous aerobic treadmill work for 30 minutes at 70% max heart rate or 3 bouts of 10 minutes of exercise at 70% of max heart rate with two 10 minute break periods in between, totaling 30 minutes of aerobic work. Following exercise, both CON and DIS groups demonstrated a significant improvement in VO2max (CON 35.39±1.99 to 38.19±2.03; DIS 36.18±1.82 to 39.33±1.75), heart rate max (CON 183.5±3.11 to 187.17±3.06; DIS 179.06±2.75 to 182±2.61), decreases in SBP(CON 119±1.82 to 115.11±1.50; DIS 117.44±1.90 to 112.67±1.66), DBP(CON 72.56±1.65 to 70.56±1.06; DIS 71.56±1.59 to 69.56±1.43), augmentation index (CON 17.17±2.17 to 14.9±1.92; DIS 19.71±2.66 to 13.91±2.46), central pulse wave velocity (CON 8.29±0.32 to 6.92±0.21; DIS 7.85±0.30 to 6.83±0.29), peripheral PWV (CON 9.49±0.35 to 7.72±0.38; DIS 9.11±0.37 to 7.58±0.47), and significant increases in average forearm blood flow (CON 4.06±0.12 to 4.34±0.136; DIS 4.26±0.18 to 4.53±0.15), peak FBF following reactive hyperemia (CON 28.45±0.094 to 29.96±0.45; DIS 29.29±0.46 to 30.6±0.38) area under the curve of FBF (CON 28.65±1.77 to 30.4±1.08; DIS 30.52±1.9 to 31.67±1.44) and AUC peak FBF following RH (CON 222.3±5.68 to 231.95±4.42; DIS 230.81±6.91 to 237.19±5.39. These data suggest that for healthy people either four weeks of continuous or discontinuous aerobic training is effective in improving measures of fitness and vascular health.
