Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to determine the optimal time to take caffeine I order to maximize muscular strength and muscular endurance. There have been many studies done that have shown that caffeine has the ability to improve both muscular strength and endurance due to many different effects that it has in the central nervous system. However, there is still a very intriguing question: when is the optimal time to take caffeine in order to maximize performance? It is known that caffeine has its peak effects occur about 45 minutes after ingestion. By taking caffeine 45 minutes before exercise, the peak effects would occur at the beginning of the workout, and by taking it 15 minutes before the exercise, the peak effects would occur in the middle of the workout, when the body is becoming fatigue. This study is aimed to figure out which of these scenarios is the most effective.
Download or read book Sport and Exercise Nutrition written by Susan A. Lanham-New and published by John Wiley & Sons. This book was released on 2011-08-10 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: Please note that digital editions do not include all the illustrations found in the printed book. Now widely adopted on courses throughout the world, the prestigious Nutrition Society Textbook series provides students with the scientific basics in nutrition in the context of a systems and disease approach rather than on a nutrient by nutrient basis. In addition books provide a means to enable teachers and students to explore the core principles of nutrition and to apply these throughout their training to foster critical thinking at all times. This NS Textbook on Sport and Exercise Nutrition has been written to cover the latest information on the science and practice of sport and exercise nutrition. A key concept behind this textbook is that it aims to combine the viewpoints of world leading nutrition experts from both academia/research and a practical stand point. Plus where necessary there are additional practitioner based authors to ensure theory is translated into practice for each chapter in the form of either ‘practice tips' or ‘information sheets' at the end of relevant chapters. The textbook in essence can be divided into three distinct but integrated parts: Part 1: covers the key components of the science that supports the practice of sport and exercise nutrition including comprehensive reviews on: nutrients both in general and as exercise fuels; exercise physiology; hydration, micronutrients; and supplements. Part 2: moves into focusing on specific nutrition strategies to support different types of training including: resistance; power/sprint; middle distance/speed endurance; endurance; technical/skill, team; and specific competition nutrition needs. The unique format of this textbook is that it breaks down nutrition support into training specific as opposed to the traditional sport specific support. This reflects the majority of current sport and exercise requirements of the need to undertake concurrent training and therefore facilitating targeted nutrition support to the different training components through the various macro and micro training cycles. Part 3: explores some of the practical issues encountered in working in the sport and exercise nutrition field and includes key sport related topics such as: disability sport; weight management; eating disorders; bone and gut health; immunity; injury; travel; and special populations and situations. READERSHIP: Students of nutrition and dietetics at both undergraduate and postgraduate level. All those working in the field of nutrition and related health sciences.
Download or read book Effects of Caffeine Gum on Muscular Strength and Power in Recreationally Active Females written by Lindsay D. Montgomery and published by . This book was released on 2020 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research indicates that a moderate dose of caffeine may enhance muscular strength and power, particularly in males. Less is known on caffeine’s impact on muscular performance in females. The purpose of this study was to determine the effects of a 200 mg dose caffeine gum on muscular strength and muscular power in recreationally active females. Nineteen women participated in 3 laboratory sessions, the first being the familiarization trial. During the next two visits, the participants were given either 200 mg of caffeine gum or a placebo gum, rested for 15 minutes, completed a 10 minute warm-up, then performed performance testing consisting of maximal jump height testing on a force plate, followed by one repetition maximum testing for the bench press and leg press. While the caffeine resulted in higher mean differences for all tests, there were no significant differences between caffeine or placebo trials (p > 0.05) for any performance measures except the maximal squat jump (p = 0.04). In conclusion, a 200 mg dose of caffeine is not sufficient to improve muscular strength and some instances of muscular power. This is a novel finding, and future studies should look at altering time to absorption or higher dosing of caffeine gum.

Download or read book Impact of Caffeine on Strength and Endurance written by Ella Knight and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Caffeine is a well-established ergogenic aid believed to increase strength and muscular endurance. An increase in strength suggests a centralized impact, or an “outflow” effect, on the central nervous system (CNS). An increase in muscular endurance suggests an impact of caffeine on peripheral factors such as the myoneural junction or others that locally impact muscular contractions. The present study was conducted to determine the predominant impact of caffeine, either on central or peripheral factors that govern muscular contraction, or both. Data concluded that (1.) muscular strength increased from control in both the caffeine and placebo trials, and (2.) there was no improvement in muscular endurance in the caffeine and placebo trial when compared to control; however, during the isokinetic endurance test, there was a modest increase in peak torque in the caffeine trial when compared to control. This study was conducted with approval from the Hanover College Human Subjects Institutional Review Board.

Download or read book The Effect of an Energy Drink on Acute Muscle Strength and Fatigue in Young Males written by Michelle Hawley and published by . This book was released on 2012 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: The popularization of energy drink use as a supplement to exercise is steadily increasing, especially among young adult males. However, the effects of energy drinks on muscular performance in young adults have yet to be clearly elucidated. Eight male subjects (mean age: 23.3 ± 4.3 yrs, height: 181.0 ± 5.3 cm, fat percent 17.8 ± 5.2%, and weight 85.3 ± 12.6 kg) completed this randomized double-blinded cross over study. The purpose of this study was to determine differences in acute muscular strength and endurance and Profile of Mood States (POMS) scores between three treatments (RockStar, sugar-free RockStar, and sugar-free caffeine-free Placebo). It was hypothesized that there would be no significant differences in acute peak torque and endurance of the knee extensors and flexors or on fatigue and vigor subscores from the POMS questionnaire. Each man was tested randomly at least 1 week apart. Diet and time of day were held constant across trials. Peak torque of knee extensors and flexors at 60, 180, 240 degress/second and fatigue index and total work were calculated by performing 50 repetitions at 240 degrees/second. There were no significant differences in peak torque, fatigue index, or total work measures or in subjective measures of fatigue or vigor from the POMS between the treatments. This study indicates that RockStar energy drinks have no acute ergogenic effects in young men performing isokinetic strength or endurance testing.
