Book excerpt: Studienarbeit aus dem Jahr 2021 im Fachbereich Gesundheit - Sportwissenschaft, Note: 1,0, Friedrich-Alexander-Universität Erlangen-Nürnberg, Veranstaltung: Sporternährung, Sprache: Deutsch, Abstract: In der vorliegenden Hausarbeit wurde die Studie von Lara et al. (2014) mit dem Titel „Caffeine-containing energy drink improves physical performance in female soccer players“, als Ausgang genutzt. In dieser Studie, wurde von den Teilnehmerinnen 3mg Koffein pro Kilogramm Körpergewicht in Form eines Energydrinks konsumiert, mit dem Ziel herauszufinden, ob der Konsum einen Einfluss auf die physische Leistungsfähigkeit im Fußball hat. Zusätzlich wurden 4 weitere Studien, welche auch den Koffeinkonsum und seinen Effekt auf die physische Leistungsfähigkeit untersucht haben, herangezogen, um die Ergebnisse der Ausgangsstudie kritisch zu hinterfragen, zu belegen oder zu widerlegen. Die Hausarbeit ist gegliedert in einen Hauptteil, in welchem die einzelnen Studien und deren Ergebnisse vorgestellt werden. Für viele Menschen ist Koffein ein alltägliches Genussmittel, welches zur geistigen und körperlichen Anregung und vor allem bei Müdigkeit in Mengen von 50 mg bis 500 mg/Tag konsumiert wird. „Koffein ist eine leicht diffusible Substanz, die besonders in das Zentralnervensystem und in die Muskulatur gelangt und mehrere Wirkungsansätze hat“ (Hottenrott & Seidel, 2017). Koffein kommt in mehr als 60 Pflanzen vor. Die wohl bekannteste Pflanze, in welcher Koffein vorkommt, ist die Kaffeepflanze. Koffein ist damit einer der Hauptwirkstoffe von Kaffee und wird häufig gegen Müdigkeit konsumiert (Pauli & Girreßer, 2014). Heutzutage gibt es aber auch zahlreiche andere Lebensmittel und Getränke, denen Koffein künstlich zugesetzt wurde. Eines dieser Getränke ist der Energydrink. Energydrinks werden häufig vor der Aufnahme sportlicher Aktivitäten konsumiert, da dem Koffein, im Kontext Sport, leistungssteigernde Effekte nachgesagt werden. Cureton et al. (2007) und Ganio et al. (2009) belegten z.B. mit ihren Studien, dass die Einnahme von Koffein zu einer erhöhten Ausdauerleistungsfähigkeit führt. Auch wurde eine Leistungssteigerung durch die Einnahme von Koffein hinsichtlich der Reaktionsschnelligkeit, der motorischen Koordination und von Kraftleistungen nachgewiesen (Hottenrott & Seidel, 2017). Aufgrund seiner leistungssteigernden Wirkung stand Koffein bis 2004 auf der Dopingliste. Damit Koffein eine Wirkung auf den Menschen hat, ist insbesondere die Dosis bedeutend.

Download or read book The Effects of Energy Drinks on Division 1 Soccer Midfielders written by Jordan D. Vitale and published by . This book was released on 2020 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Caffeine is a popular ergogenic aid that is commonly used in young athletes to improve performance. Energy drinks are just one of the many ways to consume caffeine. There have been mixed results about whether or not caffeine actually improves different types of exercise performance. The studies that do exist focus primarily on the effects that caffeine has on males. There is very little research on the effects of caffeine on females, especially during anaerobic exercise. The purpose of this study is to expand the known effects that energy drinks have on anaerobic exercise performance and explore a new population of female soccer midfielders through the use of a Wingate test. A total of 10 participants were chosen from a division I collegiate women’s soccer team and were asked to volunteer in the study. Each participant was informed of testing protocol and expectations before agreeing to participate and signing a consent form. Peak power and rate of fatigue was the main focus of the study. All of the data was analyzed through the use of an independent t-test to discover the relationship between energy drink consumption and peak power, and energy drink consumption and rate of fatigue. It is hypothesized that the consumption of an energy drink prior to a Wingate anaerobic test would result in overall better anaerobic performance, specifically with increased power and a lower fatigue index.

Book excerpt: From the bestselling author of The Ascent of Money and The Square and the Tower “A dazzling history of Western ideas.” —The Economist “Mr. Ferguson tells his story with characteristic verve and an eye for the felicitous phrase.” —Wall Street Journal “[W]ritten with vitality and verve . . . a tour de force.” —Boston Globe Western civilization’s rise to global dominance is the single most important historical phenomenon of the past five centuries. How did the West overtake its Eastern rivals? And has the zenith of Western power now passed? Acclaimed historian Niall Ferguson argues that beginning in the fifteenth century, the West developed six powerful new concepts, or “killer applications”—competition, science, the rule of law, modern medicine, consumerism, and the work ethic—that the Rest lacked, allowing it to surge past all other competitors. Yet now, Ferguson shows how the Rest have downloaded the killer apps the West once monopolized, while the West has literally lost faith in itself. Chronicling the rise and fall of empires alongside clashes (and fusions) of civilizations, Civilization: The West and the Rest recasts world history with force and wit. Boldly argued and teeming with memorable characters, this is Ferguson at his very best.

Download or read book Caffeine in Food and Dietary Supplements written by Leslie A. Pray and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Caffeine in Food and Dietary Supplements is the summary of a workshop convened by the Institute of Medicine in August 2013 to review the available science on safe levels of caffeine consumption in foods, beverages, and dietary supplements and to identify data gaps. Scientists with expertise in food safety, nutrition, pharmacology, psychology, toxicology, and related disciplines; medical professionals with pediatric and adult patient experience in cardiology, neurology, and psychiatry; public health professionals; food industry representatives; regulatory experts; and consumer advocates discussed the safety of caffeine in food and dietary supplements, including, but not limited to, caffeinated beverage products, and identified data gaps. Caffeine, a central nervous stimulant, is arguably the most frequently ingested pharmacologically active substance in the world. Occurring naturally in more than 60 plants, including coffee beans, tea leaves, cola nuts and cocoa pods, caffeine has been part of innumerable cultures for centuries. But the caffeine-in-food landscape is changing. There are an array of new caffeine-containing energy products, from waffles to sunflower seeds, jelly beans to syrup, even bottled water, entering the marketplace. Years of scientific research have shown that moderate consumption by healthy adults of products containing naturally-occurring caffeine is not associated with adverse health effects. The changing caffeine landscape raises concerns about safety and whether any of these new products might be targeting populations not normally associated with caffeine consumption, namely children and adolescents, and whether caffeine poses a greater health risk to those populations than it does for healthy adults. This report delineates vulnerable populations who may be at risk from caffeine exposure; describes caffeine exposure and risk of cardiovascular and other health effects on vulnerable populations, including additive effects with other ingredients and effects related to pre-existing conditions; explores safe caffeine exposure levels for general and vulnerable populations; and identifies data gaps on caffeine stimulant effects.
Download or read book Wearable Sensor Technology for Monitoring Training Load and Health in the Athletic Population written by Billy Sperlich and published by Frontiers Media SA. This book was released on 2020-02-13 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several internal and external factors have been identified to estimate and control the psycho-biological stress of training in order to optimize training responses and to avoid fatigue, overtraining and other undesirable health effects of an athlete. An increasing number of lightweight sensor-based wearable technologies (“wearables”) have entered the sports technology market. Non-invasive sensor-based wearable technologies could transmit physical, physiological and biological data to computing platform and may provide through human-machine interaction (smart watch, smartphone, tablet) bio-feedback of various parameters for training load management and health. However, in theory, several wearable technologies may assist to control training load but the assessment of accuracy, reliability, validity, usability and practical relevance of new upcoming technologies for the management of training load is paramount for optimal adaptation and health.
