CARDIOVASCULAR RESPONSES TO HIGH INTENSITY AEROBIC AND ANAEROBIC EXERCISES.      Parker, A., Messersmith, P., Beil, K., Mahoney, K., Jones, K., McKenzie, J.A., and McCole, S.D.

Methods: Healthy, physically active females (n = 11) and males (n = 9) each performed a VO2max test, Wingate Anaerobic Test (WAT), and 30 s of one-leg maximal isokinetic extension and flexion (180 °/s) of the lower leg (ISO) at least 48 hours apart. Each test was preceded by 10 minutes of quiet rest for measurement of baseline values. Cardiac output (Q), stroke volume (SV), and heart rate (HR) were measured every 10 s using impedance cardiography. Blood pressure was measured immediately at the end of test. Mean arterial pressure (MAP) and total peripheral resistance (TPR) were calculated using standard formula. Peak values were analyzed for significant differences (p < 0.05) using repeated measures ANOVA and post-hoc testing with Bonferroni correction. Results: All data reported as mean + SE. Participants averaged 23 + 1 yr, 19.8 + 1.4 %, and 52.9 + 2.3 mL/kg/min for age, body fat, and VO2max, respectively.    Test Q HR SV MAP TPR  (L/min) (bpm) (mL) (mm Hg) (dynes/s/cm-5) VO2max 19.5 + 1.0 193 + 2 105.8 + 5.8 109 + 2 473 + 27 WAT 16.8 + 1.0 169 + 3* 99.3 + 5.5 101 + 3* 523 + 40 ISO 14.6 + 1.0*# 151 + 3*# 96.0 + 5.8 102 + 3* 605 + 41* All data reported as mean + SE.  * significantly different from VO2max test, # significantly different from WAT Conclusion: ISO does not impose a similar CV load as VO2max or WAT testing.
