However, both the application and language of the mechanical constructs are not always adhered to when applied to biological systems, which can lead to errors and misunderstandings within the scientific literature. Here we address three topics that seem to be common points of confusion and misconception, with a specific focus on sports biomechanics applications: 1) joint reaction forces as they pertain to loads actually experienced by biologi- cal joints; 2) the partitioning of scalar quantities into directional components; and 3) weight and gravity alteration. For each topic, we discuss how mechan- ical concepts have been commonly misapplied in peer-reviewed publications, the consequences of those misapplications, and how biomechanics, exercise science, and other related disciplines can collectively benefit by more carefully adhering to and applying concepts of classical mechanics. 11 Keywords: joint reaction force; weightlessness; misunderstandings; myths; 12 communication 13 1. Background 14 Biomechanics, as defined by Hatze (1974), \is the study of the structure 15 and function of biological systems by means of the methods of mechanics" 16 (p. -
Biomechanical Modelling in Sports – Selected Applications
Biomechanical modelling in sports – selected applications U. Hartmann1, G. Berti2, J.G. Schmidt1, T.M. Buzug3 1University of Applied Sciences Koblenz, RheinAhrCampus, Germany. 2NEC Europe Ltd., C&C Research Laboratories, St. Augustin, Germany. 3University of Luebeck, Institute for Biomedical Engineering, Germany. Abstract In the past decade computer models have become very popular in the fi eld of sports biomechanics due to the exponential advancements in computer technology. Biomechanical computer models can roughly be grouped into multi-body mod- els and numerical models. The theoretical aspects of both modelling strategies will be shortly introduced. This chapter focuses on the presentation of instructive application examples each representing a specialized branch within the fi eld of modelling in sports. Special attention is paid to the set-up of individual models of human body parts. In order to reach this goal a chain of tools including medical imaging, image acquisition and processing, mesh generation, material modelling and fi nite element simulation becomes necessary. The basic concepts of these tools are thoroughly described and fi rst results presented. The chapter ends with a short outlook into the future of sports biomechanics. Keywords: biomechanical models, mesh generation, fi nite elements, sports 1 Introduction 1.1 Why models? The fi eld of sports biomechanics suffers from one very severe restriction; in general it is not possible for ethical reasons to measure forces and pressure inside the human body. Thus, typical measurement technology in biomechanics works on the interface between the body and the environment. Force platforms for instance dynamically quantify reaction forces when a person is walking or run- ning across the sensor, electromyography (EMG) monitors action potentials of contracting muscles with electrodes detached to the human skin. -
Ultramarathons
Name Date Ultramarathons A marathon is a long-distance running event. A marathon is officially 26.2 miles long. When a running event is longer than 26.2 miles, it is called an ultramarathon. Over 70,000 people complete ultramarathons every year. There are two kinds of ultramarathons. In the first kind of ultramarathon, runners have to cover a specific distance—50 miles, for example. In the second kind of ultramarathon, runners have a limited amount of time, such as 24 hours, to cover as much distance as they can. Some ultramarathons are run as loops around a track or course. Others are run on trails through forests, deserts, or mountains. Many ultramarathons that are run on trails include natural obstacles that a runner will have to overcome, such as rocky paths or bad weather. Ultramarathons are run all over the world. There is an ultramarathon on every continent, even Antarctica. Because it is so expensive to travel to Antarctica, those who want to participate in an Antarctic ultramarathon usually have to pay many thousands of dollars. The most famous race across Antarctica is called The Last Desert Race. Runners pay over $14,000 to compete in this race. They must also buy special equipment to protect themselves against the extreme cold. People who want to train to run in an ultramarathon should first gain experience running regular marathons. Once you have completed a few marathons, you can add more and more distance every time you run. Besides practicing, there are a few other things you can do to help you prepare to run an ultramarathon. -

Beginning Mountain Bike Racing in the Tricities TN/VA: Sweat and Gear Without Fear
Natasha Snyder [email protected] Beginning Mountain Bike Racing in the TriCities TN/VA: Sweat and Gear without Fear Natasha Snyder <[email protected]> Author Natasha Snyder and her beloved racing steed on a 35 mile training ride. Alvarado Station Store, Creeper Trail, Abingdon, VA. Natasha is a retired mountain bike racer from Bristol TN who specialized in cross country and cyclocross, with several trophy finishes. Natasha Snyder [email protected] The world of mountain bike racing is exciting, exhausting, varied—and accessible. If you are a competent mountain biking enthusiast who has mastered basic riding skills and built a decent level of fitness, you may be ready to explore the next step: the local racing circuit. With some readily available equipment and determination, you could begin collecting trophies in no time. Most adults who purchase a mountain bikes are simply recreational riders, looking to enjoy a comfortable, ecologically-sound, human-powered ride around their neighborhood or perhaps a quick ride to the beach during vacations. After all, mountain bikes are stylistically diverse, slower and safer than motorcycles, and more comfortable than skinny road bicycles. However, sometimes a casual rider becomes a true “enthusiast,” which is what people involved in bicycle racing call those who are more than recreational riders, but not quite elite athletes. Once the desire to go fast surpasses the desire to arrive home clean and comfortable, the time may have arrived for you to consider preparing to enter a local or amateur mountain bike race here in the Tri Cities and surrounding region.
