Stanzione and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction: Crossover point is characterized as the point during exercise when one transitions energy substrates from fat to carbohydrate predominance. Crossover point is applicable to most exercise endeavors and varies based on exercise intensity. However, less is known about crossover point and its specificity towards sports type. Understanding the relationship between crossover point and sport type would be beneficial in understanding the metabolic response to exercise across exercise modalities. In addition, the current state of the research has primarily focused on endurance sports with respect to crossover point; thus, there is a paucity of data on non-endurance athletes (e.g., Combat Sport Athletes). Athletes participating in high intensity sports are an ideal population to study, because most data on substrate use are focused on endurance-related activities. Furthermore, crossover point is intensity driven; but it has been well documented that the constituents of the diet can directly play a role as well. Most studies in this area have focused on a few days of dietary intervention or analyses of an athlete's usual intake. There is information lacking on the immediate influence of a pre-exercise meal on exercise metabolism or the crossover point. Therefore, the purpose of this study were as follows: 1) to analyze differences between Runners, Triathletes, Rowers and CrossFit Athletes, 2) to analyze differences in time to crossover point between a group of high intensity sport athletes (Combat Sport Athletes) and a group of low- to moderate- intensity sport athletes (Runners); and, 3) to examine if two acute dietary interventions and a fasted intervention could alter baseline time to crossover point in a group of healthy athletes. Healthy athletes were defined as those without any metabolic disorders and who could participate in maximal and submaximal exercise. Methods: Participants were recruited from the surrounding Philadelphia area to participate in a four-session crossover study design consisting of a maximal oxygen consumption (VO2max) test and three submaximal tests, each separated by at least one week. The submaximal tests were preceded by either a bolus feeding of carbohydrate, fat or no meal (in a randomized fashion), 30 minutes prior to exercise. Participants were measured via indirect calorimetry during all exercise tests, and crossover point was determined using respiratory exchange ratio (RER), defined as reaching an RER >0.85 with no return below 0.85 for the remainder of the test. Each participant was also measured for anthropometrics, body composition and dietary intake at each session. A one-way ANOVA was applied to determine differences between Runners, Triathletes, Rowers and CrossFit Athletes. A 2x2 factorial ANOVA was conducted to determine if differences existed in heart rate and percent (%) VO2max at crossover point between Combat Sport Athletes and Runners during a VO2max and submaximal test. A Kruskal-Wallis test was applied to determine if differences existed in time to crossover point between Combat Sport Athletes and Runners during a VO2max and submaximal test. A Kruskal-Wallis test was applied to identify differences between sport groups. A Friedman's test was applied to denote the directional effects of two acute dietary interventions and a fasted intervention on time to RER. All statistical procedures were performed with the Statistical Package for the Social Sciences (SPSS) version 24.0, with alpha levels set a priori to p

Available in PDF, EPUB and Kindle. Book excerpt: Caffeine is the world's most popular drug! Almost all of us start our day with a jolt of caffeine from coffee, tea or cola. And many of us crave chocolate when we're stressed or depressed. Without it we're lethargic, head-achy and miserable. Why? Why do we crave caffeine? How much do we really know about our number one drug of choice? Here is the first natural, cultural, and artistic history of our favorite mood enhancer--how it was discovered, its early uses, and the unexpected parts it has played in medicine, religion, painting, poetry, learning, and love. Weinberg and Bealer tell an intriguing story of a remarkable substance that has figured prominently in the exchanges of trade and intelligence among nations and whose most common sources, coffee, tea, and chocolate, have been both promoted as productive of health and creativity and banned as corrupters of the body and mind or subverters of social order. Some Highlights From the World of Caffeine Balzac's addiction to caffeine drove him to eat coffee, as some schizophrenic patients are observed to do today, and may have killed him Mary Tuke breaks the male monopoly on tea in England in 1725 The ways caffeine functions as a smart pill Goethe's responsibility for the discovery of caffeine Did a mini Ice Age help bring coffee, tea and chocolate to popularity in Europe? What is the mystery of coffee's origin? As good as gold: the stories of how caffeine, in its various forms, was used as cash in China, Africa, Central America and Egypt What does the civet cat have to do with the most costly coffee on earth today? The World of Caffeine is a captivating tale of art and society -- from India to Balzac to cybercafes -- and the ultimate caffeine resource.
