Lately, modeling and optimizing endurance performance has become popular. Optimal strategies have been calculated for running as well as for cycling. Since most of these studies are of theoretical nature, we performed a series of experiments to determine whether race performance can actually be improved using mathematical optimization in a realistic scenario. The optimal strategy was based on t...

Older pedestrians and cyclists are vulnerable road users, comprising a substantial proportion of all road fatalities world-wide. Pedestrian fatalities constitute between 20 and 30 percent of road fatalities, while cyclist deaths range from 2 percent in Australia to 10 percent in Denmark, Belgium, Germany and Sweden to 23 percent in the Netherlands. Older pedestrians and cyclists are over-repres...

The influences of sex and age upon endurance performance have previously been documented for both running and swimming. A number of recent studies have investigated how sex and age influence triathlon performance, a sport that combines three disciplines (swimming, cycling and running), with competitions commonly lasting between 2 (short distance: 1.5-km swim, 40-km cycle and 10-km run) and 8 h ...

To provide data for fatigue life prediction and testing of structural components in off-road bicycles, the objective of the research described herein was to quantify the loads input to an off-road bicycle as a result of surface-induced loads. A fully instrumented test bicycle was equipped with dynamometers at the pedals, handlebars, and hubs to measure all in-plane structural loads acting throu...

OBJECTIVE This paper examines the relationship between bicycle collisions and the amount of cycling at the local level. Most previous research has focused on national and city comparisons, little is known about differences within a city (the mesoscale). METHODS This study mainly used three types of data sets relating to bicycle collisions, use of bicycles and local neighbourhood characteristi...

BACKGROUND India is motorising rapidly. With increasing motorisation, road traffic injuries are predicted to increase. A third of a billion children travel to school every day in India, but little is known about children's safety during the school commute. We investigated road traffic injury to children during school journeys. METHODS We conducted a cross-sectional survey in Hyderabad using a...

The present study was conducted on buffaloes that were non-cycling (heifers, n=32; lactating, n=13) or cycling (heifers, n=11; lactating, n=27) and in the buffaloes that conceived (heifers; n=11; lactating, n=23)or failed to conceive (heifers, n=32; lactating, n=17) subsequent to artificial insemination. Plasma samples were analyzed for thyroid stimulating hormone, thyroid hormones, glucose, to...
