Weightlifting Training and Biomechanics covers a gamut of training and technique from the perspective of Soviet era sport science to modern radical, departures in theory of biomechanics: “Can There Be Such A Thing As An Asian Pull”; “Equilibrium in Weightlifting”; “The Foot, the Ankle Joint and Asian Pull”. “Asian pull’ technique is in all probability an effort to circumvent gravity by finding the path of least resistance for the body’s movements, which means these movements need not be designed to raise body center of mass as high as possible (as in the Russian pull) before squatting under the barbell. “The Asian pull technique is antithetical to Russian protocols which stipulate the lifter remain flat - footed as trunk and thighs straighten in unison during the explosion phase (see figure 3). Much of the explosion phase of the Asian pull is carried out with shoulder joints behind the vertical line of the bar with heels raised as legs straighten.” “Peculiarities of balance, equilibrium and stability are not unique to weightlifting. In point of fact they can even be considered 'normal aberrations' in athletics; given the extraordinary complexity of the human body's movement possibilities. Furthermore, the high incidence of injuries in American sport can be traced to a catastrophic outcome of strength and conditioning training, therapeutics and the like; where an athlete's movements are choreographed to conform to rigid, arbitrarily conceived limitations; especially linear (Charniga, 2015 - 2017). Five articles have appeared in the EWF Science journal with another two awaiting publication.

Introduction to Weightlifting Training and Technique I.P. Zhekov and various authors This book consists of translations of selected sections of two books: Ilya Zhekov’s The Biomechanics of the Weightlifting Exercises and Junior Weighlfiting by L.S. Dvorkin. European coaches and sport scientist have justifiably referred to Zhekov’s book as “god’s book of weightlifting”. Zkekov’s book incorporates unique perspectives from actual practice, biomechanics and even engineering concepts. In fact Zhekov left weightlifting later in his career to work for the Russian space agency, i.e., a seamless transfer from weightlifting biomechanics to rocket science. The rest o the book consists of various articles about weightlifting biomechanics, flexibility from R.A. Roman, A. Lukhashev, R.P. Moroz and others. “A correct execution of the movement is performed when there is no full extension of the knees, nor a significant rise onto the toes. The squat under begins when the athlete has straightened his knees to an angle of 165 - 170° and has only begun to rise onto the toes.” “A rational and consequently economical movement should begin with as great as speed as possible from the very beginning. (I.P. Zhekov, 1972) …”the weightlifter as a self – tuning system is confronted with the always present task to find such a movement structure which conforms to the required laws of physiology and will produce the maximum motor - effect. “the skill to execute the squat under in the presence of a slower barbell speed is also indicative of better technique; It is namely this skill that is important for lifting maximum weights”. I.P. Zhekov, 1976 “The feet, like the spine, are the support and “springing” apparatus of man. The arch permits the feet to become a “spring” . I.P. Zhekov, 1976

A System of Multi – Year Training in Weightlifting, by Alexsei Siderovitch Medvedyev Alexsei Medvedyev was a world champion weightlifter (+90 kg class); PhD, served two stints as the head coach of the Soviet national team; author of numerous articles and books on weightlifting training. This particular text was written by him with sections composed by other faculty of the institute of sport in Moscow where Medvedyev was head of the weightlifting faculty. For instance, weightlifting biomechanics expert Alexandr Lukhashev wrote the chapter on “Biomechanical Fundamentals of the Snatch and the Clean”. Lukhashev was the first to devise a method of studying the snatch and the clean and jerk recording of bar trajectory, muscle EMG, force platform (support reaction) and joint angles simultaneously. “The weightlifters’ speed - strength training chapter was written mostly by Yuri Verkhoshansky. The text covers the complex of factors which are involved in the training of weightlifters: programming training, classification and sequencing of exercises, teaching the classic exercises, planning and organization of restoration. All in all an excellent overview of the multifaceted structure of Soviet era weightlifting sport science. Unlike all but useless western literature emanating from US universities the Soviets relay on the science of experience as many of the top weightlifting sport scientists were former lifters and coaches.

The Female in Weightlifting features a series of essays about the peculiarities of female weightlifters. Some history and the challenges of the participation of females in weightlifting “De- masculinization of strength”; “How the female weightlifter outgrew the lady bar” are presented. Unique stereotype debunking essays about how females ‘express’ strength’ “Expression of Strength in Weightlifting”; prepare for competition attempts: “Comparison of Warm Up Protocols of High Class Male and Female Weightlifters”. “Discrete alterations in facial expression, in all probability, mirror the female lifter's intrinsic abilities to optimize tension of muscles, i.e., to eliminate unnecessary tension for effective rapid switching the disposition of the body during the weightlifting exercises.” “The 'sleeping' female weightlifter receiving the full weight of the barbell in the low squat in figure 5 is a unique 'expression' of muscular strain, i.e., an ambiguity of nature.” “The point here is not point a finger, but to make the point: the strength of today’s women lifters is beyond the equipment, originally designed for a “weaker sex”, whatever that is.” An original and unique theory of the female weightlifter’s low injury susceptibility is presented: “Shouldn’t female weightlifters be injury prone”. … the ability to react quickly, in many respects, faster than males, to unanticipated circumstances, loss of balance, falling and so forth, with very rapid reflexive release of muscle tension to dissipate and/or otherwise re - distribute mechanical energy.” Three essays of this book have appeared in the EWF Science journal with another awaiting publication.

Introduction to The Training of the Weightlifter, by Robert Ansovitch Roman Robert Roman is one of the genuine founding fathers of weightlifting sport science. He recognized early on, in the words of another Soviet sport scientist that: “the technique is the training”. It is not possible to separate the two. A national level lifter in the early 1950s for Soviet Wings he was national coach in the late 1960s and became a professor of weightlifting at Moscow State University. My brief meeting of Robert Roman at the 1983 Spartakiade is described in the foreward. “This text is devoted to those who wish to devote themselves to weightlifting and achieve high results.” The majority of the research carried out in USSR of barbell trajectory was done by Roman and/or was either inspired by or direct offshoots. “The most essential and distinguishing peculiarities of a weightlifter’s training are shown, with respect, to such characteristics as: a list of barbell exercises utilized and their quantity; the volume of the training loads; the quantity of high intensity work in the various exercises; the resistance and the number of repetitions per set.” “The information is based on experimental research and practical experience.

Stroke is one of the leading causes of physical disability around the world, resulting in significant motor deficits and ultimately reduced gait performance. In order to regain or improve motor function, stroke patients will undergo rehabilitation. Current rehabilitation techniques are labour-intensive and time-consuming for both the therapist and the patient. Therefore, not all patients receive the recommended quantity and quality of rehabilitation. To improve the gait rehabilitation process, robot-assisted gait rehabilitation has been receiving increased interest over the past few years. The research in this thesis aims to demonstrate feasibility of robotic gait rehabilitation devices which are designed to be easy to use, simple and compact. The Linkage-based Gait Trainer (LGT) was the first device developed and is an overground gait rehabilitation device consisting of a four-bar linkage end-effector mechanism. The literature review suggested the design could be an effective gait rehabilitation device while minimising the components required. The design of the LGT was validated with a healthy human participant, and kinematic data showed that the device successfully constrained the user’s foot motion to a pre-defined gait trajectory. The imposed trajectory of the LGT is set by the linkage design and cannot be changed. To allow for modification to the trajectory a subsequent device (robotic Re-Link Trainer [rRLT]) was developed. The rRLT also uses a four-bar linkage, however the spatiotemporal parameters of gait, such as walking speed, stride length and cadence, can be varied to accommodate a wider range of users with different limb lengths and desired walking speeds. A trial with healthy participants was carried out to validate the rRLT’s design and its function. The results confirmed the device’s ability to vary the spatiotemporal parameter of the gait pattern the device imposes on the user. One of the limitations of both the LGT and rRLT is that the constrained gait path is not variable. To make the device available for more users with different gait trajectories, a new gait rehabilitation device with a five-bar linkage called PRO-GaiT was developed. A trial with healthy participants confirmed the ability to change and constrain different gait trajectories during walking exercises. The research in this thesis confirmed the ability of a linkage-based overground gait rehabilitation device to constrain a user’s footpath to a desired trajectory. Such devices can vary the footpath and spatiotemporal parameters of gait to accommodate many different users. The devices developed in this research could improve the effectiveness of the gait rehabilitation by potentially increasing the time and intensity of each session while reducing the number of staff required. A rehabilitation device based on this research could be compact, easy to use and low cost thus can be widely adopted by many hospitals and clinics.

Musculoskeletal unloading in microgravity has been shown to induce losses in bone mineral density, muscle cross-sectional area, and muscle strength. Currently, an Interim Resistive Exercise Device (iRED) is being flown on board the ISS to help counteract these losses. Free weight training has shown successful positive musculoskeletal adaptations. In biomechanical research, ground reaction forces (GRF) trajectories are used to define differences between exercise devices. The purpose of this evaluation is to quantify the differences in GRF between the iRED and free weight exercise performed on a Smith machine during a squat. Due to the differences in resistance properties, inertial loading and load application to the body between the two devices, we hypothesize that subjects using iRED will produce GRF that are significantly different from the Smith machine. There will be differences in bar/harness range of motion and the time when peak GRF occurred in the ROMbar. Three male subjects performed three sets of ten squats on the iRED and on the Smith Machine on two separate days at a 2-second cadence. Statistically significant differences were found between the two devices in all measured GRF variables. Average Fz and Fx during the Smith machine squat were significantly higher than iRED. Average Fy (16.82 plus or minus.23; p less than .043) was significantly lower during the Smith machine squat. The mean descent/ascent ratio of the magnitude of the resultant force vector of all three axes for the Smith machine and iRED was 0.95 and 0.72, respectively. Also, the point at which maximum Fz occurred in the range of motion (Dzpeak) was at different locations with the two devices.Amonette, William E. and Bentley, Jason R. and Lee, Stuart M.

This textbook presents the main principles of visual analytics and describes techniques and approaches that have proven their utility and can be readily reproduced. Special emphasis is placed on various instructive examples of analyses, in which the need for and the use of visualisations are explained in detail. The book begins by introducing the main ideas and concepts of visual analytics and explaining why it should be considered an essential part of data science methodology and practices. It then describes the general principles underlying the visual analytics approaches, including those on appropriate visual representation, the use of interactive techniques, and classes of computational methods. It continues with discussing how to use visualisations for getting aware of data properties that need to be taken into account and for detecting possible data quality issues that may impair the analysis. The second part of the book describes visual analytics methods and workflows, organised by various data types including multidimensional data, data with spatial and temporal components, data describing binary relationships, texts, images and video. For each data type, the specific properties and issues are explained, the relevant analysis tasks are discussed, and appropriate methods and procedures are introduced. The focus here is not on the micro-level details of how the methods work, but on how the methods can be used and how they can be applied to data. The limitations of the methods are also discussed and possible pitfalls are identified. The textbook is intended for students in data science and, more generally, anyone doing or planning to do practical data analysis. It includes numerous examples demonstrating how visual analytics techniques are used and how they can help analysts to understand the properties of data, gain insights into the subject reflected in the data, and build good models that can be trusted. Based on several years of teaching related courses at the City, University of London, the University of Bonn and TU Munich, as well as industry training at the Fraunhofer Institute IAIS and numerous summer schools, the main content is complemented by sample datasets and detailed, illustrated descriptions of exercises to practice applying visual analytics methods and workflows.
