OBJECTIVES The objective of the present study was to determine the incidence of acute spinal cord injuries (ASCI) in all forms of horse riding in New South Wales (NSW) for the period 1976-1996. Other aims of the present study were to compare and contrast ASCI with vertebral column injuries (VCI) without neurological damage and to define appropriate safety measures in relation to spinal injury i...
The aim of this study is to verify the effect of indoor horse riding exercise on basal physical exercise and lumbar muscular function. The subjects included were 20 healthy females, who participated in the horse riding exercise using SRider (Rider Co. & ChonbuK National Univ, Korea) for 30 minutes per day, 3 days per week, over a period of 8 weeks. The subjects were divided into 4 groups as fol...
BACKGROUND The purpose of this study was to characterize the physiological demands of a riding session comprising different types of recreational horse riding in females. METHODS Sixteen female recreational riders (aged 17 to 54 years) completed an incremental cycle ergometer exercise test to determine peak oxygen consumption (VO₂peak) and a 45-minute riding session based upon a British Horse...
INTRODUCTION: The prevalence of obesity in children has reached epidemic proportions with over 37% of children aged 6-11 years in the U.S. being classified as "at risk for overweight" or "overweight." Utilization of active video games has been proposed as one possible mechanism to help shift the tide of the obesity epidemic. PURPOSE: The purpose of this study was to determine if riding a stati...
The Segway Human Transporter (HT) is a one person dynamically selfbalancing transportation vehicle. The Segway Robot Mobility Platform (RMP) is a modification of the HT capable of being commanded by a computer for autonomous operation. With these platforms, we propose a new domain for human-robot coordination through a competitive game: Segway Soccer. The players include robots (RMPs) and human...
This research analyzes the relationships between off-highway vehicle (OHV) riders’ patterns of prior experience and the social-psychological benefits they desire from the activity; it also examines the relationships between patterns of prior experience and environmental attitudes. The sample consists of 600 OHV riders in Utah drawn from the entire population of OHV owners within the state. The ...
on public land is not new—motorcycles have been used off-road for nearly a century (Havlick 2002).1 However, the growth in popularity of OHV use is primarily due to the introduction of all-terrain vehicles (ATVs), which began gaining popularity after being introduced in 1983, and ATV riding has become one of the fastest growing outdoor recreation activities in the country.2 Between 1982 and 200...
An experiment collected proximity data of motor traffic overtaking cycle traffic on roads with and without cycle lanes using an instrumented bicycle. The work enhances previous research which has considered the riding position of the cyclist and whether or not the cyclist was helmeted, while controlling for vehicle type. The analysis shows that significantly wider passing distances are adopted ...
This paper describes a response acquisition system composed of some spindle accelerometers and a time synchronized on-board GPS receiver developed in order to collect the dynamic response of vehicle riding on an unpaved road. A method of time-space conversion for calculating the response spectrum is proposed to eliminate the adverse effect of time-varying speed, based on the transform from the ...
