Book Description
The purpose of this study was to analyze and determine the effects on muscular strength, endurance, and hypertrophy of a single supramaximal eccentric contraction and submaximal concentric contraction after conventional resistance training. In this study, 2 male collegiate football athletes completed four weeks of strength training on the bench press. Training was conducted 3 times per week with 1RM testing and chest circumference measurements done before training, after two weeks of training, and after four weeks of training. The independent variables were the types of contractions being performed after the strength training- eccentric or concentric. The dependent variables were performance in the 1RM bench press, ACSM push-up test, and change in chest circumference. The bench press is an exercise that is an excellent measure of upper body strength; it’s utilized in almost every recreational lifting program and used as a measure of performance for the NFL combine and power lifting competitions. The ACSM push-up test is a test that measures upper body muscular endurance and is used to assess general health in a wide range of age groups and populations. The chest circumference measurements were used to measure muscular hypertrophy as the course of training progressed. The sessions were completed with both subjects lifting together and competing to improve 1RM the most from baseline and improve amount of push-ups done from baseline. It was hypothesized that performing a supramaximal eccentric contraction after conventional strength training on the bench press would yield higher percentage increases on the 1RM, number of push-ups performed from baseline, and muscular hypertrophy from baseline. Pilot data suggested that the hypotheses made were true. Data concluded that (1) the concentric group experienced a greater increase of strength than the eccentric group after two weeks of training (6.6% compared to 5.45% from baseline); while the eccentric group experienced a greater increase in strength than the concentric group after four weeks of training (12.72% compared to 10% from baseline), (2) the eccentric group yielded a higher percent increase in push-up repetitions after two and four weeks of training (31.43% at 2 weeks and 37.14% at 4 weeks), (3) the concentric group displayed a greater increase in chest circumference and hypertrophy after two weeks and four weeks of training (2.09% at 2 weeks and 2.70% at 4 weeks).

Book Description
What is Triphasic Training? It is the pinnacle of sports performance training. Created by world renown coach, Cal Dietz, Triphasic Training breaks down dynamic, athletic movements into their three components (eccentric, isometric, and concentric), and maximizes performance gains by applying stress to the athlete in a way that allows for the continuous development of strength, speed, and power. Who uses Triphasic Training: Everyone! From elite level athletes to absolute beginners, the triphasic method of training allows for maximal performance gains in minimal time. For that reason professional athletes from all backgrounds seek out Coach Dietz each off-season to train with his triphasic system. Coach Dietz has worked with hundreds of athletes from the NFL, NHL, and MLB, as well as several dozen Olympic athletes in track and field, swimming, and hockey. What the book is about: Triphasic Training was originally a digital book with over 3,000 hyperlinks and 6 hours of video lectures, showing the reader exactly how to perform every exercise and apply the training methods. To ensure that you do not miss out on this valuable component, inside your book you will find a web link to a downloadable PDF that contains all of the hyperlinks and videos from the original digital book. The PDF is laid out to allow you to easily follow along as you read the book. Simply scroll in the PDF to the page that you are reading in the book and it will have every hyperlink and video that is on that page. The book contains over 350 pages, divided clearly into 2 parts: the “why” and the “what”. The first three sections go through the physiological basis for the Triphasic method, undulated block periodization, and general biological applications of stress. The authors will explain how to incorporate the Triphasic methods into existing programs, with complete descriptions on adapting it to virtually any scenario. Sections 4 through 7 are devoted entirely to programming, with over 3,000 exercises and 52 weeks of programs for numerous different sports. Included in the programming section are: Over 3,000 exercises, each hyperlinked to a video tutorial that shows you exactly how to perform the exercise. 5 separate 24-week training programs built for either 6 day, 5 day, 4 day, 3 day, or 2 day models. Over 6 hours of video lectures by Coach Dietz further explaining the Triphasic Training method. These lectures go even deeper into the physiology and application of what he does with his elite athletes. Over two dozen tables showing exactly when and how to modify exercises to ensure continuous improvement in your athletes. Peaking programs for football lineman or skill players, baseball, swimming, volleyball, and hockey players (among others). A complete 52 week training program for football.

Book Description
Muscle hypertrophy—defined as an increase in muscular size—is one of the primary outcomes of resistance training. Science and Development of Muscle Hypertrophy is a comprehensive compilation of science-based principles to help professionals develop muscle hypertrophy in athletes and clients. With more than 825 references and applied guidelines throughout, no other resource offers a comparable quantity of content solely focused on muscle hypertrophy. Readers will find up-to-date content so they fully understand the science of muscle hypertrophy and its application to designing training programs. Written by Brad Schoenfeld, PhD, a leading authority on muscle hypertrophy, this text provides strength and conditioning professionals, personal trainers, sport scientists, researchers, and exercise science instructors with a definitive resource for information regarding muscle hypertrophy—the mechanism of its development, how the body structurally and hormonally changes when exposed to stress, ways to most effectively design training programs, and current nutrition guidelines for eliciting hypertrophic changes. The full-color book offers several features to make the content accessible to readers: • Research Findings sidebars highlight the aspects of muscle hypertrophy currently being examined to encourage readers to re-evaluate their knowledge and ensure their training practices are up to date. • Practical Applications sidebars outline how to apply the research conclusions for maximal hypertrophic development. • Comprehensive subject and author indexes optimize the book’s utility as a reference tool. • An image bank containing most of the art, photos, and tables from the text allows instructors and presenters to easily teach the material outlined in the book. Although muscle hypertrophy can be attained through a range of training programs, this text allows readers to understand and apply the specific responses and mechanisms that promote optimal muscle hypertrophy in their athletes and clients. It explores how genetic background, age, sex, and other factors have been shown to mediate the hypertrophic response to exercise, affecting both the rate and the total gain in lean muscle mass. Sample programs in the text show how to design a three- or four-day-per-week undulating periodized program and a modified linear periodized program for maximizing muscular development. Science and Development of Muscle Hypertrophy is an invaluable resource for strength and conditioning professionals seeking to maximize hypertrophic gains and those searching for the most comprehensive, authoritative, and current research in the field.
