Book Description:
Eccentric muscle contraction, during which a muscle lengthens while under tension, is a fundamental process of human movement but a surprisingly under-researched area of exercise science. Evidence suggests that training programmes which incorporate both eccentric and concentric contractions can result in greater strength gains than concentric contractions alone, and this clearly has important implications for training and rehabilitation in sport and health. In Eccentric Exercise, leading international sport scientist Hans Hoppeler introduces the fundamental physiology and pathophysiology of eccentric muscle work, and explores the key applications of eccentric exercise in sport, rehabilitation and health. The book examines the molecular mechanisms responsible for tissue and organismic adaptations and discusses eccentric muscle-related pathology, specifically delayed onset muscle soreness. It assesses the use of eccentric exercise training in the treatment of certain disease states such as chronic obstructive pulmonary disease, heart insufficiency and sarcopenia, while a concluding chapter points to open research questions, shows the limits of the available data and highlights problems with current exercise modalities. This book is important reading for all sport and exercise scientists, clinicians working in rehabilitation, and high-level strength and conditioning coaches and trainers.

Book Description:
Essentials of Eccentric Training is the first comprehensive resource covering this innovative approach to resistance training and conditioning that produces extraordinary results. Backed by evidence-based studies and readily incorporated into training programs, eccentric training provides greater intensity to help individuals push past plateaus and increase muscular strength, endurance, and power. Using eccentric training, strength and conditioning professionals and personal trainers can also help their clients improve metabolism, manage their weight, and facilitate injury rehabilitation. The text provides the physiological explanations, exercises, and sample programs beneficial to introducing eccentric training into clients’ workouts. All facets of this exciting, power-generating modality are detailed by veteran international fitness expert Len Kravitz and champion bodybuilder and personal trainer Aaron Bubbico, who use eccentric training not only with clients but also in their own exercise regimens. The practical information in the book is supported by special features: • 70 eccentric training exercises are demonstrated through full-color photos and detailed instructions to properly illustrate techniques and minimize risk of injury. • A selection of 46 online exercise videos explain more complex workout techniques to ensure exercises are properly performed to maximize results. Symbols throughout the book indicate when videos are available online. • A selection of 24 sample workout plans, six case study workouts, and two sample eight-week training programs provide professionals with a strong starting point to build programs for their clients. • An appendix lists foundational resistance training exercises across seven popular sports. • An exercise finder categorized by muscle group makes selecting the right exercises for each client easy. After establishing a foundation of muscular physiology, the first chapters of Essentials of Eccentric Training explain the three unique ways of using eccentric training: eccentric emphasis, supramaximal training, and the two-up/one-down method. The next two chapters address specific effects of the training method: how it bolsters postworkout metabolic rate and how to minimize delayed-onset muscle soreness. The book’s final six chapters contain exercises and program designs specifically for muscular strength, muscular endurance, explosive power, weight loss, muscle size, and rehabilitation. Essentials of Eccentric Training imparts every aspect of this groundbreaking training system and its benefits in resistance exercise programs. The method presents boundless opportunities for strength and conditioning specialists and exercise professionals who work with athletes and exercise enthusiasts of all ages and fitness levels.

Book Description:
Research has demonstrated moderate evidence for exercise in the treatment of subacromial impingement syndrome (SAIS). This evidence has primarily addressed traditional concentric-eccentric resistance training with a lack of rationale for selection of contraction type, dosage, or progression of resistance. Recent literature has suggested that patients with tendinopathies respond well to eccentric training although few studies have investigated eccentric training effects on rotator cuff tendinopathy. The primary purpose of this study was to compare the effectiveness of an eccentric progressive resistance exercise (PRE) intervention to a concentric PRE intervention in adults with SAIS.

Book Description:
Seminar paper from the year 2013 in the subject Physical Therapy / Occupational Therapy, printed single-sided, grade: 1,2, University of Teesside (Physiotherapy - School of Health and Social Care), course: Designing Research Projects, language: English, comment: Physiotherapy / Master of Science in Advanced Clinical Practice in Manipulative Therapy, abstract: Complaints about shoulder disorders constitute the third most common musculoskeletal cause for visiting a general practitioner (GP). Nearly seventy-five percent of the causes are due to impingement syndrome, in which the rotator cuff tendon is affected mostly. Furthermore, high rates of recurrence and chronicity can be seen. Exercise therapy is recommended; it plays a key part in the physiotherapeutic treatment options. However, there is still a lack of knowledge concerning the best exercise. Research demonstrates good results regarding the effectiveness of eccentric exercises in tendon pathologies, in general. Although some research has been conducted in terms of impingement syndrome, there is a lack of a systematic review in this field. The purpose of a systematic review is to provide clinicians, policy and decision-makers with the highest quality knowledge. In this paper, the author proposes to carry out a systematic review of the role of eccentric exercises in impingement syndrome. The proposal begins by developing background information and explaining key concepts, which, consequently, lead to its overall rationale. Also, research hypotheses, followed by the aims and objectives, are considered. The methodological part starts with the argument why a systematic review seems somehow appropriate to the underpinning theory. Moreover, this proposal outlines the eligibility criteria and the research strategy of the search to demonstrate its methods. Subsequently, the author describes the chosen procedure of data analysis in terms of extraction and synthesis. In the final part, ethical considerations referring t

Book Description:
Eccentric training for Achilles tendinosis (AT) has been reported to significantly improve patient symptoms. There has been no biomechanical explanation on the mechanism for specific rehabilitation technique. The purpose of this study was to determine changes in muscle architecture that occurred as a result of Achilles tendinosis injury and a subsequent eccentric rehabilitation program. Twenty-five patients (age, 53.3 ± 17.5 years) diagnosed with AT participated in 6 weeks of rehabilitation. Specific exercises for the ankle plantar flexors consisted of maximal load eccentric muscle action using 3 sets of 15 repetitions. Patients also completed a protocol for AT, which consisting of traditional rehabilitation. Medial gastrocnemius (GM) and lateral gastrocnemius (GL) muscle fascicle length and thickness were measured with ultrasound at 2-week intervals from initial treatment day to the end of 6 weeks of rehabilitation. Medial gastrocnemius fascicle length increased (45.1 ± 10.5 mm to 51.4 ± 10.5 mm; P = .22) between the initial day of rehabilitation and after 6 weeks of rehabilitation. But, GM thickness (16.3 ± 3.5 mm to 16.8 ± 2.0 mm), GL fascicle length (47.2 ± 10.0 mm to 47.1 ± 7.4 mm), and GL thickness (14.9 ± 5.2 mm to 14.4 ± 2.7 mm) did not change as a result of rehabilitation. A 6-week eccentric-biased exercise increased the GM muscle fascicle length by 12%, but GM thickness, GL fascicle length, and GL thickness did not change as a result of rehabilitation. Eccentric training for the treatment of AT is well recognized, but the mechanism of action has not been previously reported. A 6-week eccentric training protocol increased the GM muscle fascicle length by 12%, and this correlated with improvement in a validated patient outcome scoring system. Further study is warranted to determine a predictive relationship between improvement of GM fascicle length and outcome scores. Levels of Evidence: Therapeutic, Level IV: Case series.
