Aerodynamic drag in cycling: methods of assessment.

When cycling on level ground at a speed greater than 14 m/s, aerodynamic drag is the most important resistive force. About 90% of the total mechanical power output is necessary to overcome it. Aerodynamic drag is mainly affected by the effective frontal area which is the product of the projected frontal area and the coefficient of drag. The effective frontal area represents the position of the ...

Intensity of exercise during road race pro-cycling competition.

PURPOSE The aim of this study was to quantify the intensity of competition during two professional bicycle stage races: the Tour de France (Tour) and Vuelta a España (Vuelta). METHODS The HR responses of 18 world class cyclists were recorded during the races and compared with HR ranges that corresponded to four intensities of exercise that were measured in the laboratory with an incremental t...

The Aerodynamic Drag of Parafoils

The parafoil is an aerodynamic decelerator that uses the concept of parachute and airfoil aerodynamics. The device has been used as a parachute for high-precision delivering of payload (military and civilian), to recover sounding rockets, for various tethered applications (to carry instrumentation for weather survey, air pollution measurements, radar tracking systems), and as recreational parac...

Field-measured drag area is a key correlate of level cycling time trial performance

Drag area (Ad ) is a primary factor determining aerodynamic resistance during level cycling and is therefore a key determinant of level time trial performance. However, Ad has traditionally been difficult to measure. Our purpose was to determine the value of adding field-measured Ad as a correlate of level cycling time trial performance. In the field, 19 male cyclists performed a level (22.1 km...

Reproducibility of a Laboratory Based 1-km Wattbike Cycling Time Trial in Competitive Cyclists

The purpose of this study was to evaluate the reliability of a 1-km cycling time trial using a Wattbike cycling ergometer in competitive cyclists. Ten competitive male cyclists (mean ± SD; 63.9 ± 5.1 mL•kg -1 •min -1 ) performed a VO2max test and a familiarization of the 1-km time trial (TT) on the same day, and 3 separate 1-km TT (TT1, TT2 and TT3) separated by >24 hours. Mean performance time...
