The interaction between training mode and caffeine: Cardiovascular responses at rest and during exercise. - 103 p.

Thesis (Ph.D.)--State University of New York at Buffalo, 2002.

Exercise training has been shown to improve cardiovascular function at rest and during physical stress compared to inactivity. However, the effects of training mode (aerobic vs resistive) on cardiovascular responses during both physical and psychological stresses are unknown. In addition, there are no studies that compare the effect of training mode on the cardiovascular responses to pharmacological stressor, caffeine, and whether they differ from that of physiological stressors.

520 $a Exercise training has been shown to improve cardiovascular function at rest and during physical stress compared to inactivity. However, the effects of training mode (aerobic vs resistive) on cardiovascular responses during both physical and psychological stresses are unknown. In addition, there are no studies that compare the effect of training mode on the cardiovascular responses to pharmacological stressor, caffeine, and whether they differ from that of physiological stressors.
520 $a This study examined the effect of training mode (aerobic vs resistive) on the blood pressure (systolic blood pressure, diastolic blood pressure, mean blood pressure) and heart rate responses to Physical (dynamic exercise at absolute and relative work rates and isometric exercise at 33% of the maximum voluntary contraction) and psychological stressors (mental stress) alone (<italic> study #1</italic>), and in combination with a pharmacological stressor, caffeine (<italic>study #2</italic>).
520 $a <italic>Study #1</italic> showed that aerobic and resistive training improved the regulation of cardiovascular responses to physical stresses compared to being sedentary. Similar to aerobic training, resistive training lowered systolic blood pressure and heart rate responses to exercise compared to sedentary group. However, unlike aerobic training, resistive training was accompanied with higher diastolic blood pressure responses to exercise. Results indicated that aerobic training altered blood pressure differently than resistive training.
520 $a <italic>Study #2</italic> showed that aerobic-trained subjects were more effectively able to counteract the pressor effect of a pharmacological stressor, caffeine, when introduced alone or combined with physiological stressors. The aerobic-trained group exhibited attenuated mean blood pressure in response to caffeine at rest and a suppressed response during physical and mental stress compared to the resistive and sedentary groups. The reduced pressor effect of caffeine, an adenosine receptor inhibitor, at rest and its suppression during exercise may be attributed to various adaptations of aerobic exercise training.
520 $a In addition, the heart rate response to caffeine at rest and during exercise differed among groups. Unlike the resistive and the sedentary groups, the aerobic group exhibited a suppressed bradycardic response to caffeine at rest. During exercise Caffeine decreased the tachycardic response to exercise in the aerobic-trained group, but had no effect on the heart rate of the resistive and sedentary groups.
520 $a <italic>It is concluded that: Central and peripheral adaptations of aerobic exercise training are more effective than those of resistive training in counteracting the negative effects of various stresses, to which the cardiovascular system may be exposed during daily living</italic>.
