#1
Stephen Harvey, Chris Rissel, Mirjam Pijnappels
Falls among older adults remains a significant public health issue. Bicycling positively influences falls risk factors including reduced balance, muscle weakness, and low self-perceived confidence in maintaining balance. However, this association has not been systematically examined. We recruited 107 community-dwelling participants aged 65 and over in the Netherlands to determine the relationship between bicycling and fall risk factors. Participants completed 3 questionnaires on cycling behaviour and balance confidence, and undertook 5 fall related physical performance tasks encompassing tests of balance, strength, gait and endurance...

Background In Germany there are more than 70 million bicycles. Because of technical progress, over 200,000 electro-assisted bikes were sold in Germany in 2010 alone. In 2013, the number increased to 410,000. Currently more than 1.6 million electric bicycles are used here. One of the largest user groups are seniors. Accident researchers fear an increased risk of accidents/injuries. Methods For one year, all cycling accidents involving electric bicycles and senior citizens were collected and analysed in 23 hospitals of the TraumaNetwork NorthWest and by the local police authorities...

Objective: Bicycling is an affordable way to increase access to employment, schooling, and services and an effective measure against obesity. Bikeshare programs can make bicycling accessible to diverse populations, but little evidence exists on their adoption in low-resource neighborhoods. Our study examined factors associated with bikeshare use in a metropolitan area in the southern United States. Methods: We performed a retrospective cross-sectional analysis of a database of clients (N=815) who rented a bicycle from Zyp Bikeshare in Birmingham, Alabama between October 2015 and November 2016...

With the increasing popularity of mountain biking, also known as off-road cycling, and the riders pushing the sport into extremes, there has been a corresponding increase in injury. Almost two thirds of acute injuries involve the upper extremities, and a similar proportion of overuse injuries affect the lower extremities. Mountain biking appears to be a high-risk sport for severe spine injuries. New trends of injury patterns are observed with popularity of mountain bike trail parks and freeride cycling. Using protective gear, improving technical proficiency, and physical fitness may somewhat decrease the risk of injuries...

BACKGROUND: Cycling is considered to have a positive effect on public health through increased physical activity. In Norway, the e-bike is seen as a way of getting more people to cycle. However, the motorized assistance of an e-bike potentially eliminates any physical activity associated with its use. It is possible that the assumed health effect of increased cycling is "erased" through a reduction in other physical activities (a substitution effect). In this paper we study the public health effects of e-bikes using a combined cross-sectional and quasi-experimental design...

The boom in bike-sharing is receiving growing attention as societies become more aware of the importance of active non-motorized traffic modes. However, the low usage of this transport mode in China raises concerns. The primary objective of this study is to explore factors affecting bike-sharing usage and satisfaction degree of bike-sharing among the bike-sharing user population in China. Data were collected by a questionnaire survey in Ningbo. A bivariate ordered probit (BOP) model was developed to examine simultaneously those factors associated with both bike-sharing usage and satisfaction degree of bike-sharing among users...

Cycling is becoming one of the most popular forms of recreation and transport the world over, but cyclists still have a high level of vulnerability. A bicycle helmet is an important safety device available to cyclists, but little is known regarding possible determinants of helmet use among adults. This study aims at providing information on helmet usage patterns in Italy and identifying the factors associated with bicycle helmet use. Data on 2072 bicycle riders from an Italian friends of cycling association aged 18 years or older who had ridden a bicycle in the last month were collected using an ad-hoc questionnaire via the web...

Most low-income Americans fail to meet physical activity recommendations. Inactivity and poor diet contribute to obesity, a risk factor for multiple chronic diseases. Health promotion activities have the potential to improve health outcomes for low-income populations. Measuring the effectiveness of these activities, however, can be challenging in community settings. A "Biking for Health" study tested the impact of a bicycling intervention on overweight or obese low-income Latino and African American adults to reduce barriers to cycling and increase physical activity and fitness...

This paper examines if, in a lower-income minority neighborhood, bicycling practices and bicycle-environment preferences of Blacks and Hispanics were different from Whites. During the summer of 2014, surveys were mailed to 1537 households near a proposed cycle track on Malcolm X Boulevard in Roxbury, MA. On the Boulevard, intercept surveys were distributed to cyclists and observations noted about passing cyclist's characteristics. Data were analyzed from 252 returned-mailed surveys, 120 intercept surveys, and 709 bicyclists...

INTRODUCTION: The use of electric bicycles (E-bike) has dramatically increased. E-bikes offer convenient, environmental-friendly, and less expensive alternative to other forms of transport. However, E-bikes provide a new public health challenge in terms of safety and injury prevention. This study is the first to specifically investigate the E-bike related orthopaedic injuries, based on a national trauma registry. METHODS: Data from a National Trauma Registry were reviewed for patients hospitalized following E-bike related injuries...

China has a historic system of wide cycle tracks, many of which are now encroached by cars, buses and bus stops. Even with these conditions, college students still bicycle. On campuses, students park their bikes on facilities ranging from kick-stand-plazas to caged sheds with racks, pumps and an attendant. In other countries, including Canada, some of the newer cycle tracks need to be wider to accommodate an increasing number of bicyclists. Other countries will also need to improve their bike parking, which includes garage-basement cages and two-tiered racks...

The motion of parts of an object is usually perceived relative to the object, i.e., nonretinotopically, rather than in retinal coordinates. For example, we perceive a reflector to rotate on the wheel of a moving bicycle even though its trajectory is cycloidal on the retina. The rotation is perceived because the motion of the object (bicycle) is discounted from the motion of its parts (reflector). It seems that the visual system can easily compute the object motion and subtract it from the part motion. Bikes move usually rather predictably...

With the steady rise of health and environmental awareness, the number of bicyclists is increasing. However, there are few epidemiologic studies on bicycling under the influence (BUI). The aim of this study was to determine the prevalence of BUI and the associated risk factors in a representative Korean population. The data of 4,833 adult bicyclists who participated in the Korean National Health and Nutrition Examination Survey (2010-2012) were analyzed. Among the 4,833 participants investigated in this study, 586 (12...

Kinematic measurements conducted during bike set-ups utilise either static or dynamic measures. There is currently limited data on reliability of static and dynamic measures nor consensus on which is the optimal method. The aim of the study was to assess the difference between static and dynamic measures of the ankle, knee, hip, shoulder and elbow. Nineteen subjects performed three separate trials for a 10-min duration at a fixed workload (70% of peak power output). Static measures were taken with a standard goniometer (GM), an inclinometer (IM) and dynamic three-dimensional motion capture (3DMC) using an eight camera motion capture system...

INTRODUCTION: Public bike share users have low prevalence of helmet use, and few public bike share systems make helmets available. In summer 2016, a public bike share system launched in Vancouver, BC. Each bicycle is equipped with a free helmet, in response to BC's all-ages compulsory helmet law. This study assessed the prevalence of helmet use among adult cyclists on personal and public bicycles in Vancouver. METHODS: A survey of adult cyclists (age estimated at ≥16 years) at five screen line sites and at 15 public bike share docking stations was conducted...
