    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.

  • Design of Urban Transit Rowing Bike (UTRB)
    Design of Urban Transit Rowing Bike (UTRB) A Major Qualifying Project Report Submitted to the Faculty of the WORCESTER POLYTECHNIC INSTITUTE in partial fulfillment of the requirements for the Degree of Bachelor of Science In Mechanical Engineering ________________ ________________ By Zebediah Tracy Claudio X. Salazar [email protected] [email protected] Date: August 2012 ___________________________________ Professor Isa Bar-On, Project Advisor Legend Red: Works contributed by Zebediah Tracy Blue: Works contributed by Claudio X. Salazar Green: Mutual works contributed by both Tracy and Salazar Abstract The objective of this project was to create a human-powered vehicle as a mode of urban transport that doubles as a complete exercise system. The project was constrained in scope by the requirement of affordability, under $1,000. This was accomplished through reducing complexity by utilizing a cable and pulley drive train, simplified tilting linkage and electric power assist in place of variable gears. This project successfully demonstrates that rowing can be the basis for effective human powered urban transport. Acknowledgments The UTRB MQP group would like to thank the following people for their assistance during this project. Thanks to professor Isa-Bar-On for her steadfast support and guidance over the full course of this endeavor. This report would not have been possible without her. Thanks to Derk F. Thys creator of the Thys Rowing Bike for his correspondence and for his foundational work on rowing geometry for biking. Thanks to Bram Smit for his correspondence regarding the Munzo TT linkage and his experience building a variety of innovative recumbents. Thanks to Bob Stuart, creator of the Car Cycle for his correspondence regarding his groundbreaking work and engineering insights.

  • Physiological Contributions to Successful Downhill Mountain Bike Performance
    PHYSIOLOGICAL CONTRIBUTIONS TO SUCCESSFUL DOWNHILL MOUNTAIN BIKE PERFORMANCE EDINBURGH NAPIER UNIVERSITY, MSC BY RESEARCH SUZANNE L. HADDEN A THESIS SUBMITTED IN PARTIAL FULFILMENT OF THE REQUEST OF EDINBURGH NAPIER UNIVERSITY, FOR THE AWARD OF MASTER OF SCIENCE BY RESEARCH. JUNE 2011 ABSTRACT Purpose: To, one, investigate the anatomical and physiological attributes of Downhill mountain bike athletes and, two, to determine the influence of these inherent physiological attributes on Downhill race performance. Methods: The study consisted of two testing components; laboratory- and field-based testing. Laboratory study: An anthropometric profile was determined from seven trained and competitive DH athletes (age 21 ± 5 years). Peak power output and time to peak power were determined by six, 6-second maximal sprints, performed on an SRM stationary ergometer. Cadence was restricted during five sprints (60, 80, 100, 120 and 140 rpm) to determine optimal cadence for achieving peak power. Field study: Twelve trained and competitive DH athletes (age 20 ± 5 years) performed two timed runs of a National Championship DH course. Heart rate was recorded and two GPS units (attached to the bicycle and helmet) recorded speed (kmhr-1), distance (m), time (seconds) and impacts (g). Results: Laboratory study: DH cyclists have predominantly mesomorphic somatotypes (mean somatotype values, 2.1,4.7,3.0) with a mean sum of 8 skinfolds, 68.7 ± 19.8 mm. Sprint testing revealed peak power output (23.36 ± 2.12 Wkg-1) was achieved at restricted cadence of 110 rpm and time to peak power output was 1.5 ± 0.9 seconds. Field study: DH race run time was 178.57 ± 12.10 seconds.
