Leg cycling tracking by dynamic vision

Journal of Biomechanics, 1997
This study describes a method of tracking of human body limbs from a monocular sequence of perspective images. These objects and the associated articulations must be modelled. The principle of the method is based on the interpretation of image features as the three-dimensional perspective projections points of the object model and an iterative process ...

Energetics of best performances in track cycling

Medicine &amp Science in Sports &amp Exercise, 1998
VO2max and best performance times (BPTs) obtained during maximal voluntary trials over 1, 2, 5, and 10 km from a stationary start were assessed in 10 elite cyclists. Steady-state VO2 and peak blood lactate concentration ([La]b) were also determined in the same subjects pedaling on a track at constant submaximal speeds. The energy cost of cycling (Cc, J.

Aerodynamics of Track Cycling

2012
The aim of this thesis was to identify ways in which the velocity of a track cyclist could be increased, primarily through the reduction of aerodynamic drag, and to determine which factors had the most significant impact on athlete performance. An appropriate test method was set up in the wind tunnel at the University of Canterbury to measure the ...

Tracking the Metal of the Goblins: Cobalt’s Cycle of Use

Environmental Science & Technology, 2011
Cobalt is a vital element in many technological applications, which, together with its increasing end-use in batteries, makes it important to quantify its cycle of use. We have done so for the planet as a whole and for the three principal cobalt-using countries - China, Japan, and the United States - for 2005.

The safety of urban cycle tracks: A review of the literature

Accident Analysis & Prevention, 2013
Cycling has to be a safe activity, and perceived as such, if bicycle trips by all populations are to increase and the public health benefits are to be realized. A key characteristic of developed countries with a high cycling mode share is their provision of cycle tracks--separated bikeways along city streets--on major routes.

Energetics of Indoor Track Cycling in Trained Competitors

International Journal of Sports Medicine, 1988
Steady-state track VO2 was estimated by means of the retroextrapolation method in seventeen competitive male cyclists at speeds ranging from 28 to 43 km.h-1. Peak VO2 was also determined using an ergocycle multistage test (80 rev.min-1). Results showed large VO2 variations at similar speeds on the track (SEE greater than 10% Y; n = 17).

The physics of road and track cycling

2020
Even if the first bicycle was invented in Germany in 1817 by Karl von Drais, the Physics of cycling probably started in 1869 with the work of the Scottish mechanical engineer W.J.M. Rankine entitled On the dynamical principles of the motion of velocipedes.
