Reports of cardiovascular responses to head-stand posture are lacking in literature. The results of the various responses, respectively, to the supine, erect, and head-stand posture, are as follows: heart rate/min 67, 84, and 69; brachial arterial pressure mm Hg 92, 90, and 108; posterior tibial arterial pressure mm Hg 98, 196, and 10; finger blood flow ml/100 ml min 4.5, 4.4, and 5.2; toe blood flow ml/100 ml min 7.1, 8.1, and 3.4; forehead skin temperature C 34.4, 34.0 and 34.3; dorsum foot skin temperature C 28.6, 28.2, and 28.2. It is inferred that the high-pressure-capacity vessels between the heart level and posterior tibial artery have little nervous control. The high-pressure baroreceptors take active part in postural adjustments of circulation. The blood pressure equating mechanism is not as efficient when vital tissues are pooled with blood as when blood supply to them is reduced. man; heart rate; blood flow; skin temperature Submitted on January 3, 1963

This study examined the acute effects of caffeine on the cardiovascular system during dynamic leg exercise. Ten trained, caffeine-naive cyclists (7 women and 3 men) were studied at rest and during bicycle ergometry before and after the ingestion of 6 mg/kg caffeine or 6 mg/kg fructose (placebo) with 250 ml of water. After consumption of caffeine or placebo, subjects either rested for 100 min (rest protocol) or rested for 45 min followed by 55 min of cycle ergometry at 65% of maximal oxygen consumption (exercise protocol). Measurement of mean arterial pressure (MAP), forearm blood flow (FBF), heart rate, skin temperature, and rectal temperature and calculation of forearm vascular conductance (FVC) were made at baseline and at 20-min intervals. Plasma ANG II was measured at baseline and at 60 min postingestion in the two exercise protocols. Before exercise, caffeine increased both systolic blood pressure (17%) and MAP (11%) without affecting FBF or FVC. During dynamic exercise, caffeine attenuated the increase in FBF (53%) and FVC (50%) and accentuated exercise-induced increases in ANG II (44%). Systolic blood pressure and MAP were also higher during exercise plus caffeine; however, these increases were secondary to the effects of caffeine on resting blood pressure. No significant differences were observed in heart rate, skin temperature, or rectal temperature. These findings indicate that caffeine can alter the cardiovascular response to dynamic exercise in a manner that may modify regional blood flow and conductance.

This paper presents a study of work shift analysis on security workload. Six security employees were investigated in this study for two work shift periods (morning and night). T - test was used to determine the differences of psychophysiological fatigue before and after working. Survey was conducted to identify some complaints. Pulse, blood pressure (systolic and diastolic), and skin temperature were also determined to define the physiological fatigue. In addition, motivation, psycho - social, and psychological complaints were identified to define the psychological fatigue by using an independent developed questionnaire. The results then shows some differences about the physical fatigue aspect in which the average are 32,2 before working and 28,2 after working. The average pulses aspects are 65.6 beats/min and 93.2 beats / min before and after working, the average blood pressure are 121,8 mm Hg and 127,7 mm Hg before and after working for systolic aspect. The average blood for diastolic aspect are 71 mm Hg and 75,9 mm H before and after working. Skin temperature is 34.8 C before working and 34.6 C after working. Result of this study also shows some differences on psychological fatigue where the mean work motivation was 21.5 before working and 24.7 after working, psycho-social was 13,5 before working and 14.3 after working, and psychological complaint was 50.8 before working and 40.83 after working.
