Barthel Readiness potential in different states of physical activation and after ingestion of taurine and/or caffeine containing. To investigate the influence of taurine and caffeine containing drinks and physical stress on the cortical movement-preparation, the readiness potentials or "Bereitschaftspotentiale" (BPs), preceding voluntary self-placed pedalling movements, were examined after different states of exhaustion on an ergometer. 15 (13 right-handed) healthy men, aged between 22–30, participated in a randomised, cross over, double-blind, placebo controlled study.
BPs were averaged out of artefact free EEG-segments from more than 90 triggered events, measured at 17 electrodes of the 10 : 20 system. With increasing effort the BPs were enlarged differently depending on the drink consumed. In placebo trials after exhaustive exercise premovement negative potential curves could be seen even in frontal areas. With caffeine the BPs increased after lower workload, achieving a level, which was reached in the placebo trials only after submaximal physical activation.

[Amino Acids. 2000. 5) A taurine and caffeine-containing drink stimulates cognitive performance and well-being.
Caffeine- and taurine-containing drinks have been on the European market for about a decade, and research on the individual constituents of these drinks indicates an improvement in cognitive performance resulting from consumption of such drinks.
In this double-blind, placebo-controlled study using 10 graduate students, we obtained the P300 components of event-related potential (ERP) waveforms following an auditory oddball paradigm, measured motor reaction time, and applied the d2 test for the assessment of attention. Status of mood was assessed by the “Basler-Befindlichkeitsbogen” questionnaire, a standard test for evaluation of feelings of well-being. Measurements were made at night, prior to and starting one hour after consumption of energy drink ingredients or placebo. At the end of the experiment (midnight), P300 latency and motor reaction time were significantly longer compared with baseline measurements in the placebo group, but were unchanged in the energy drink group.

To determine the effect of a taurine-enriched drink “Red Bull” on performance, 10 endurance-athletes performed three trials.
After 60 min. cycling at approximately 70% VO2 max, the subjects pedalled to exhaustion on a cycle ergometer. During each exercise, the subjects received 500 ml of a test-drink after 30 min. submaximal cycling: “Red Bull” without taurine, without glucuronolacton (U1), “Red Bull” without taurine, without glucuronolacton, without caffeine (U2) and “Red Bull” original drink containing taurine, glucuronolacton and caffeine (U3). The heart rate level was significantly lower in U3 (p = 0,0031) 15 min. after application. The plasma catecholamines increased slightly from begin of exercise to 15 min. after application of the drinks in all trials but remained on a significantly lower level in U3 (epinephrine (p = 0,0011) and norepinephrine (p = 0,0003). Endurance time was significantly longer with “Red Bull” original in U3 (p = 0,015). Dr. K.-R. GeiB. I. Jester.

Organisation and Management Introduction and Guiding Principle Introduction The natural sciences form an important cornerstone of modern industrial and high-tech societies.
Together with the disciplines of technical application they have a key role to play in the process of technological and social change. The results of scientific research and their wide-ranging applications create the basis for innovations that impact all areas of life in our society. Within the University of Paderborn, the Faculty of Natural Sciences and its activities serve to strengthen and advance the university's profile as a "University for the Information Society".
