Gender and age distribution of motorcycle crashes in Spain.

2018

This study analysed motorcycle crashes in Spain. Ninety-nine thousand three hundred and four motorcycle crash reports filed in the years 2006-2011 were extracted from the Directorate General of Traffic database of crashes with victims. These data were analysed in terms of gender, age groups, trip purpose, type of crash, speed violation, day of the week, harm caused, use of helmet and psychophysical conditions of the driver to study the characteristics of motorcycle crashes in Spain and to assess the differences between male and female motorcycle drivers in these crashes. Significant differences were found in all the variables considered in the study, which implies gender differences in the …

Modeling offenses among motorcyclists involved in crashes in Spain.

2013

In relative terms, Spanish motorcyclists are more likely to be involved in crashes than other drivers and this tendency is constantly increasing. The objective of this study is to identify the factors that are related to being an offender in motorcycle accidents. A binary logit model is used to differentiate between offender and non-offender motorcyclists. A motorcyclist was considered to be offender when s/he had committed at least one traffic offense at the moment previous to the crash. The analysis is based on the official accident database of the Spanish general directorate of traffic (DGT) for the 2003–2008 time period. A number of explanatory variables including motorcyclist character…

Cardiorespiratory and Neuromuscular Responses to Motocross Riding

2008

The aim of the present study was to examine physiological and neuromuscular responses during motocross riding at individual maximal speed together with the riding-induced changes in maximal isometric force production. Seven A-level (group A) and 5 hobby-class (group H) motocross-riders performed a 30-minute riding test on a motocross track and maximal muscle strength and oxygen uptake (VO2max) tests in a laboratory. During the riding the mean (+/-SD) VO2 reduced in group A from 86 +/- 10% to 69 +/- 6% of the maximum (P < 0.001), whereas in group H the corresponding reduction was from 94 +/- 25% to 82 +/- 20% (P < 0.05). This relative VO2 during the riding correlated with riding speed (r = 0…

Robust dynamic comfort modeling for motorcycle riding

2015

Comfort modeling is considered a prerequisite in motorcycle design, primarily to address safety concerns and to position the product on the market. However, a comprehensive methodology for comfort modeling during the earliest development phases of a motorcycle model is still missing. Anthropometrical variation is the main noise factor to consider in comfort modeling in relation to the unavoidable variability of body segments. However, comfort is a subjective concept influencing riders' choice of motorcycle model. This work is a generalization of the robust ergonomic design methodology aimed at designing products whose ergonomic performance is insensitive to anthropometrical variation. This …

Alcohol abusive use increases facial trauma?

2016

Background Trauma is among the main death causes and morbidity in the world and is often related to the use of alcohol and its abuse has reached massive proportions, no matter if the country is developed or not, being considered as public health problem. Since there are very few randomized and prospective studies in literature about the association of facial trauma and the use of alcohol, this study aims to investigate the impact of alcohol use in facial trauma. Material and Methods This was a prospective and cross sectional study, involving facial trauma patients attended at Oral Maxillofacial Surgery Division of a State Hospital. Variables included patient´s profile, trauma etiology, faci…

Factores asociados a los accidentes de motocicleta en Barcelona, España

2019

espanolResumen: Este estudio analizo los accidentes de motocicleta y ciclomotor en Barcelona (Espana). 53.190 informes de conductores de motocicleta y ciclomotor involucrados en accidentes entre los anos 2006 y 2011 fueron extraidos de la base de datos de accidentes con victimas de la Direccion General de Trafico. Estos datos fueron analizados en terminos de sexo, grupos de edad, motivo del desplazamiento, dia de la semana, infracciones de velocidad, uso del casco y lesividad, con el objetivo de estudiar las caracteristicas de los accidentes de motocicleta y ciclomotor en Barcelona y evaluar las diferencias entre conductores varones y mujeres en estos accidentes. La gravedad de los accident…

Kinesiological Treatment of Early Spine Osteoarthritis in a Motorcyclist

2022

This case report speculates that the prolonged vibrations from enduro off-road sports are deleterious to the spine. The results of this case report may also aid sports physicians in better understanding this complex and relatively unknown phenomenon. No published data are present in the current literature that demonstrate the correlation between early spine osteoarthritis from enduro motorcycle overuse and the long-term management effects of a non-invasive kinesiological approach to reduce pain and inflammation and improve spine mobility and muscle strength.

New frontiers of Robust Design with applications to motorcycles

2012

Most of the literature on Robust Design has so far focused on making technical performances of products and processes as much insensitive as possible to the action of noise factors, often representing physical variables. When studying the human-machine interaction, we can try to achieve system robustness to “human” noise factors in general, by considering variations in: psychological impact, body shapes and cognitive psychology in usage. These are new frontiers of Robust Design. This work started from three research lines, namely Kansei Engineering, Robust Ergonomic Design, and Human Machine interface design, the former involving cognitive and psychological aspects within product placement,…
