Performance analysis of a world-class sprinter during cycling grand tours.

چکیده
This investigation describes the sprint performances of the highest internationally ranked professional male road sprint cyclist during the 2008-2011 Grand Tours. Sprint stages were classified as won, lost, or dropped from the front bunch before the sprint. Thirty-one stages were video-analyzed for average speed of the last km, sprint duration, position in the bunch, and number of teammates at 60, 30, and 15 s remaining. Race distance, total elevation gain (TEG), and average speed of 45 stages were determined. Head-to-head performances against the 2nd-5th most successful professional sprint cyclists were also reviewed. In the 52 Grand Tour sprint stages the subject started, he won 30 (58%), lost 15 (29%), was dropped in 6 (12%), and had 1 crash. Position in the bunch was closer to the front and the number of team members was significantly higher in won than in lost at 60, 30, and 15 s remaining (P < .05). The sprint duration was not different between won and lost (11.3 ± 1.7 and 10.4 ± 3.2 s). TEG was significantly higher in dropped (1089 ± 465 m) than in won and lost (574 ± 394 and 601 ± 423 m, P < .05). The ability to finish the race with the front bunch was lower (77%) than that of other successful sprinters (89%). However, the subject was highly successful, winning over 60% of contested stages, while his competitors won less than 15%. This investigation explores methodology that can be used to describe important aspects of road sprint cycling and supports the concept that tactical aspects of sprinting can relate to performance outcomes.

Speed Trends in Male Distance Running
The major cycling "Grand Tours" have shown an attenuation of performance over the last decade. This has been interpreted as circumstantial evidence that newer anti-doping strategies have reduced the use of performance-enhancing drugs. To examine this idea under more controlled conditions, speed trends for world class 5000 m, 10000 m, and marathon performances by men from 1980 to 2013 were analy...

A model is presented of the force and power produced during a world record sprint to provide coaches and athletes with a method to determine how much force to use during strength training and what velocity to train at. In addition to specific velocity of strength training, the coach or athlete can estimate the biomechanical position of the athlete by determining that position for the relevant s...

This study examined the relationship between coping strategies and performance–goal discrepancy (PGD) with positive and negative effects before and after the competition. Sixty-two Iranian male sprinter runners, aged from 21 to 26 years, completed the Brief COPE (Carver, 1997) and the PANAS (Watson, Clark, & Tellegen, 1988) questionnaire two hours before and six hours after the competition. The...
متن کامل1 The grand tour via geodesic interpolation of 2 - frames
Grand tours are a class of methods for visualizing multivariate data, or any finite set of points in n-space. The idea is to create an animation of data projections by moving a 2-dimensional projection plane through n-space. The path of planes used in the animation is chosen so that it becomes dense, that is, it comes arbitrarily close to any plane. One inspiration for the grand tour was the ex...
