BACKGROUND Bicycle use, despite its proven health and other benefits, is rarely part of everyday travel for many people due to the perceived risk of injury from collision crashes. This article investigated the role of physical vs. attention conspicuity in preventing bicycle crashes involving a motor vehicle in New Zealand. METHODS The Taupo Bicycle Study involved 2590 adult cyclists recruited...

The aim of this study was to assess and compare by numerical simulations analytical models the resistive forces, mechanical power energy cost using two different types road helmets (standard vs aero helmet). An elite cyclist scanned on racing bicycle, wearing his competition gear helmets. Numerical Computational Fluid Dynamics were carried-out at 11.11 m/s (40 km/h) 20.83 (75 km/) extract drag ...

BACKGROUND Mandatory helmet legislation for cyclists is the subject of much debate. Opponents of helmet legislation suggest that making riders wear helmets will reduce ridership, thus having a negative overall impact on health. Mandatory bicycle helmet legislation for children was introduced in Ontario, Canada in October 1995. The objective of our study was to examine trends in children's cycli...

objectives the aim of this study was to obtain the epidemiology of this type of injury in tabriz imam reza hospital as a referral center in northwest of iran during 2009 to 2012. materials and methods one hundred bicycle-related patients during the three years were entered in this descriptive cross-sectional study. patient’s demographics, place and time of crash, mechanism of trauma, helmet and...

Bicycle helmet wearing is currently not legally enforced in Ireland and little is known about the self-reported practice amongst young children. The principal aim of this study was to assess self-reported helmet wearing amongst a sample (n = 314) of primary school children (aged 8-13 years) attending disadvantaged schools in Dublin. Approximately 86% of the sample owned a bike and provided a re...

BACKGROUND Helmets have been shown to decrease the risk of brain injury; however, helmets must be worn correctly and fit well in order to be effective. The objective of this study is to determine whether kindergarten-aged children could learn and retain appropriate helmet wearing technique through an educational bicycle safety program. METHODS Retrospective analysis of scores in questionnaire...

With the remarkable increase in the prevalence of obesity in the USA and most high-income countries of the world over the last 20 years, there is an urgent need to promote an increase in physical activity by persons of all ages. One of the methods to do so is the use of bicycling for both commuting and recreation. Bicycles were introduced in the 19th century and now number about 1 billion world...

Australia is one of the few countries with current uniform helmet legislation (introduced in the early 1990s), but many cyclists continue to ride without head protection. Many peer-reviewed epidemiological studies published over the past decade have investigated the efficacy of helmets in preventing serious injury to bicycle riders involved in crashes. This report presents a formal summary quan...

Traumatic brain injuries (TBIs) are a major health and socioeconomic problem throughout the world, with an estimated 10 million deaths and instances of hospitalization annually. Numerical methods such as finite element (FE) methods can be used to study head injuries and optimize the protection, which can lead to a decrease in the number of injuries. The FE head models were initially evaluated f...
