Physiological Responses to Cola Ingestion
Research Quarterly. American Alliance for Health, Physical Education and Recreation, 1977Abstract On four separate occasions resting, fasted adults ingested 10 oz of a cola-flavored soft drink containing either 0, 22.5, 35, or 150 mg caffeine. Heart rate, blood pressure, and plasma free fatty acid (FFA) and glucose values were obtained before and at 15, 30, 60, 90, 120, 180 and 360 min after the feeding.

PHYSIOLOGIC RESPONSES TO TRAINING
Clinics in Chest Medicine, 1994Endurance training improves exercise tolerance principally by inducing structural and biochemical changes in the exercising muscles. These changes yield improved oxygen delivery to the site of muscle metabolism, which improves oxygen use and forestalls the onset of anaerobic metabolism. The physiologic stress of heavy exercise is thereby reduced.

The physiological responses to running downhill
European Journal of Applied Physiology and Occupational Physiology, 1974The metabolic cost of one healthy male subject aged 31 years, running on a range of gradients from +5% to −45% at speeds varying from 6.0 km · h−1 to 18.0 km · h−1, on a motor-driven treadmill, has been investigated. The results showed that the “apparent” efficiency of running increased with gradient from 0 to −15% and then remained fairly constant at ...

Physiological responses in blood phobics
Behaviour Research and Therapy, 1984Abstract Eighteen patients with blood phobia were shown a film of thoracic operations containing large amounts of blood. Their heart rate (HR) and blood pressure (BP) were measured continuously before, during and after the watching of the film. The group data showed a diphasic response; an increase in HR and BP from baseline to the beginning of the ...

Conductive, Physiologically Responsive Hydrogels
Langmuir, 2010Coupling molecular sensing with electrical conductivity may provide an important and valuable resource in assessing disease pathology. Here, we introduce pH-responsive hydrogels with homogeneously synthesized gold (Au) nanoparticles that reversibly alter conductivity through pH-induced volumetric swelling.

Physiologically responsive gene therapy
Molecular Medicine Today, 1998The goal of physiologically responsive gene therapy is to allow a host's endogenous regulatory mechanisms to control the production of therapeutic proteins (effectors). Ideally, effector production would be switched on in response to specific signals, stay within therapeutic limits and be switched off when no longer needed.

The physiologic response of CPR training
Annals of Emergency Medicine, 1991To determine the physiologic response of CPR training.Cardiovascular and ventilatory parameters were investigated during 40 minutes of CPR performance and during a maximum exercise test in seven female and nine male subjects (mean age, 30 years; range, 16 to 49 years).During CPR performance, mean oxygen consumption (0.36 +/- 0.10 L/min), and mean ...

Physiologic Responses to Primary Blast
The Journal of Trauma: Injury, Infection, and Critical Care, 1998Primary blast injuries are produced by the blast shock wave. The critical determinant of survival is pulmonary injury, but acute cardiorespiratory responses to blast exposure are not well understood. The aim of this study was to investigate these changes.Twenty anesthetized rats were exposed to moderate blast overpressure, 10 animals receiving thoracic

Physiological Responsiveness During Hypnosis
International Journal of Clinical and Experimental Hypnosis, 19904 physiological measures--electromyogram, respiration rate, heart rate, and skin conductance--were recorded for 11 high and 11 low hypnotizable Ss. It was hypothesized (a) that physiological responsiveness during hypnosis would vary depending on the nature of the task instructions, and (b) that high hypnotizable Ss would show more physiological ...
