Book Description
This new title in the Encyclopaedia of Sports Medicine Series from the Medical Commission of the International Olympic Committee presents in one volume the latest information on neuromuscular function in sport and exercise. Chapters combine basic mechanistic knowledge with true applications; Topics covered include neuromuscular fatigue, neuromuscular training, and musculoskeletal loading, and special chapters examine recently developed research methodologies used during natural locomotion: high speed ultrasonography (US) and transmagnetic electrical stimulation (TMES). An important addition to the reference collections of biomechanists, sports medicine specialists, sport scientists, and graduate students in these areas, this volume is also appropriate for advanced level coaches and sport physiotherapists.

Book Description
Bicycles have been a common device to enhance physical fitness level in gyms and training centers along with solid use in competitive sport. For that reason, biomechanics of cycling has grown as a research field with many publications addressing different perspective of the interaction between the cyclist and his bicycle. The most common end point of research on biomechanics of cycling is optimization of performance and reduction of injury risk. One goal of this book is to meet the growing need for a comprehensive presentation of contemporary knowledge on biomechanics of cycling which will positively influence the activity of cycling in a global fashion. In order to accomplish this purpose, ten chapters are presented with focus on varying methods for biomechanical analysis of cycling motion. The introduction section provides an overview of the main methods for assessment of cycling motion, including motion analysis, pedal force measurements, muscle activation, anthropometry and joint kinetics. These methods are discussed in depth in individual chapters followed by chapters on characteristics of bicycles and potential perspectives to improve their configuration in order to improve performance of cyclists and reduce their overuse injury risk. Moreover, a preliminary method to train technique in cyclists is shown. A final chapter provides authors perspective on the upcoming technology that should be effective in helping training of cyclists.

Book Description
Human walking requires complex muscle coordination to produce important biomechanical functions such as balance, forward propulsion and leg swing. For healthy individuals, these tasks are often accomplished effortlessly. However, for individuals post-stroke, balance, propulsion and leg swing can be compromised. Thus, the overall goal of this research was to understand how healthy individuals respond to altered balance control via mediolateral foot placement perturbations and how specific muscles contribute to propulsion and leg swing deficits in individuals post-stroke. Controlling mediolateral foot placement is critical to maintaining balance in the frontal plane, but can be difficult post-stroke. Thus, we investigated how healthy individuals maintain their balance after mediolateral foot placement perturbations to compare to individuals post-stroke. We found that participants responded to medial foot placement perturbations using lateral hip and ankle strategies and lateral foot placement perturbations using a lateral ankle strategy, but did not use a plantarflexion strategy following either perturbation. Modeling and simulation analyses further revealed changes in hip and trunk muscle contributions to foot placement, suggesting a coordinated response of the trunk and bilateral hip abductor muscles. On average, changes in muscle contributions to mediolateral ground reaction forces, torso power, and frontal plane external moments were small. These results highlight the responses of healthy individuals to altered balance control via foot placement perturbations. Individuals post-stroke often experience propulsion and knee flexion deficits, leading to slow walking speeds and stiff-knee gait. These deficits may have several underlying causes. Thus, modeling and simulation analyses of individuals post-stroke were used to identify muscle contributions to propulsion deficits, including excess braking from the vasti, plantarflexor braking, low plantarflexor output and reliance on compensatory mechanisms. Moreover, higher vasti contributions to braking in pre-swing predicted lower knee flexion. While the rectus femoris and iliopsoas did not directly contribute to lower knee flexion acceleration in pre-swing compared to contributions from the vasti, in some cases, the rectus femoris absorbed more power and the iliopsoas contributed less power to the paretic leg. These results highlight the heterogeneity of the post-stroke population and the need to identify individual causes of walking deficits to improve rehabilitation outcomes
