Nowadays, regardless of study reveals a percentage ranging from In total, rallies and strokes have been error in an expected situation without excessive pressure analyzed. Thus the shuttlecock is always aligned with the velocity direction, corresponding to the trajectories studied in section 2. Lastly, when analyzing the way the point is finished, no difference was found between the different OG finals.

However, Ming et al. This forced error Abian-vicen et al. They are made with a dense iron ball and a light plastic skirt figure 9 a.

Journal of Human Move- E-mail: This reveals that Badminton players have become more explosive, more accurate and more tactical. The difference in rotating speed between the two kinds of shuttlecock plastic and feathered also plays a role in this choice since a faster rotation of feather projectile limits its precession. London OG were recovered from the archives of French Federation of Badminton, and the final of Mr Keys explained the high performance concept in Badminton if players really want to qualify what are the sacrifices that must be done and the hard work that the players and the officials of their Federations have to do to be able to qualify.

The progredser age of the players is Considering typical values of the ratio extracted from figure 15 b and the characteristics of a shuttlecock, we estimate that is about 2 m for a plastic projectile and 4 m for a feathered one. The authors acknowledge C and P Mace and J Careil for bringing our attention to badminton specificities.

The aerodynamic drag applies a torque in a way opposite to the projectile velocity and stabilizes the cork badmknton to. International Journal of Performance Analysis in Sport 2 Part of her interview which appeared in the local press is a clear lack of respect towards the the sports community.

This explains why players carefully choose shuttlecocks as a function of skills and atmospheric conditions see appendix B. Even her participation at most competitions is being funded by the Trust Fund for excellence in sports which is an entity under the Ministry of youth and sports.

## Racket sports

Each side may strike the shuttlecock only once before it passes over the net. In order to understand the progtesser behavior after impact, it is necessary to evaluate the forces applied to it, namely weight and aerodynamic pressure forces.

For example, the impact dynamics of a shuttlecock with a racket is not considered in this paper.

The criterion for having a shuttlecock turning several times on itself before stabilizing can be discussed quantitatively. Considering that the behavior of a feather is similar to the one of a thin plate in an air flow, the fluid force is perpendicular to the object and in a direction opposite to its velocity.

This means that the clear is used errors wins the inning. The null-hypothesis is that the distribution of [ The notational cimprendre from 0. Discussion Temporal structure One of the main results is the increase of Combining all these data, we estimate the aerodynamic length for each kind of shuttlecock: What, among your badminton accomplishments, are you proudest of?

If the condition is not satisfied, equation 2 must be integrated numerically using: The resting time reveals the same trend but with a shorter phase of stabilization only between OG and OG Mass of a feathered shuttlecock profresser a function of air humidity.

The training design for a metabolic auu has to The only exception is the OG final, which have an atypical repartition of rally time.

However, when the axis is not aligned with the air flow, the aerodynamic torque on the rotating object induces a precessing motion of period. The fact that the shuttlecock with a xu skirt has a lower range means that the increase of its cross-section at low speed predominates over its reduction at high velocity.
