Au ping pong, 58% des points sont gagnés sur le service. Vous l’aurez compris le service est crucial dans une partie de ping pong. Savoir servir au ping pong permet de se donner un avantage déterminant. Ce premier contact avec la balle vous donne toute la maîtrise du jeu : vous pourrez ainsi choisir la vitesse, la trajectoire, l’effet. En servant, vous avez carte blanche sur la première balle et préparer déjà la deuxième balle.
L’importance de maîtriser le service tient au fait que vous n’avez qu’un seul essaie pour le réussir. Contrairement au tennis, le tennis de table ne permet de bénéficier d’un deuxième service. Il faut donc s’entraîner à bien servir et travailler différente technique : service lifté, service coupé ou service latéral. Apprendre à bien servir au ping pong est un processus long et technique.
Lorsque vous jouer au tennis de table, au moment de servir, le joueur adverse ne distingue pas toujours clairement votre raquette. Les pros ont tendance à cacher le plus possible leur raquette au service pour ne pas montrer à leur adversaire leur service. Ainsi si le joueur adverse ne distingue pas votre raquette et que vous faites un effet lifté, la balle rebondira normalement sur la table mais lorsqu’elle touchera sa raquette elle partira sur la droite ou sur la gauche en dehors de la table. La seule manière de parer un tel service est de connaître les différents lifts et d’anticiper le revoit en liftant dans le sens opposé.
Voici les services qui existent au ping pong : coupé, lifté, rentrant, mou, latéral, marteau, sauté, sortant, bombe, lancé.
Dans le détail voici le fonctionnement de certains de ces services qu’il est conseillé de travailler pour améliorer grandement votre technique de jeu.
Service lifté
Le service lifté a plusieurs variantes. Il comporte presque toujours un effet latéral. Certains services liftés donne un effet de blocage qui augmente l’effet sur la balle sans lifter proprement dit : la raquette est alors quasi horizontale au moment de frapper. Le principe du service lifté est de frotter la balle par derrière avec un mouvement de poignet.
Service latéral
Le service latéral consiste à taper la balle de côté en la frottant. La trajectoire sera donc incurvée. Pour réalisé ce service latéral votre coude sera levé et donc bien décollé de votre tronc.
Service marteau
Facile à maîtriser le service marteau au ping pong est l’un des services que vous pourrez utiliser rapidement. Il consiste à imiter le mouvement d’un marteau avec la raquette. Dans la pratique il s’agit d’un service ou vous frottez la balle rapidement latéralement. Cela donne un lifté/court ou un coupé/long selon la matière dont vous frottez la balle.
Service lancé
Très rare et perturbant, ce service consiste à lancer la balle en hauteur avant de la taper. Cela oblige l’adversaire à suivre la balle des yeux et à ne pas voir le mouvement de la raquette.L’intérêt est surtout d’accroître la vitesse au moment de l’impact afin de booster l’effet de la balle lorsque celle ci est frottée.
Sur youtube de nombreuses vidéos vous explique les techniques. Vous trouverez toutes les explications dans celle ci par exemple :
N’hésitez pas à rejoindre un club de ping pong pour prendre des leçons et jouer avec des gens expérimentés pour progresser. Vous aurez toujours l’occasion de jouer en vacances car les tables de ping pong sont courantes.

Understanding COSC Accreditation and Its Importance in Horology
COSC Certification and its Stringent Criteria
Controle Officiel Suisse des Chronometres, or the Controle Officiel Suisse des Chronometres, is the authorized Swiss testing agency that verifies the precision and accuracy of timepieces. COSC accreditation is a mark of quality craftsmanship and reliability in chronometry. Not all watch brands seek COSC accreditation, such as Hublot, which instead sticks to its own stringent standards with mechanisms like the UNICO, achieving similar precision.
The Science of Precision Chronometry
The central mechanism of a mechanical timepiece involves the mainspring, which supplies power as it loosens. This mechanism, however, can be vulnerable to external elements that may influence its precision. COSC-validated movements undergo demanding testing—over 15 days in various circumstances (5 positions, three temperatures)—to ensure their durability and dependability. The tests measure:
Typical daily rate precision between -4 and +6 secs.
Mean variation, highest variation levels, and impacts of temperature variations.
Why COSC Certification Is Important
For timepiece fans and connoisseurs, a COSC-validated watch isn’t just a piece of technology but a demonstration to enduring excellence and precision. It symbolizes a timepiece that:
Offers outstanding reliability and accuracy.
Offers confidence of quality across the entire design of the watch.
Is probable to retain its worth better, making it a wise investment.
Well-known Chronometer Manufacturers
Several renowned manufacturers prioritize COSC validation for their timepieces, including Rolex, Omega, Breitling, and Longines, among others. Longines, for instance, provides collections like the Archive and Soul, which showcase COSC-accredited movements equipped with advanced materials like silicone equilibrium springs to boost resilience and efficiency.
Historical Context and the Evolution of Chronometers
The notion of the chronometer originates back to the requirement for accurate chronometry for navigation at sea, highlighted by John Harrison’s work in the 18th cent. Since the formal establishment of COSC in 1973, the accreditation has become a yardstick for evaluating the precision of luxury timepieces, continuing a tradition of excellence in watchmaking.
Conclusion
Owning a COSC-certified watch is more than an visual choice; it’s a dedication to quality and precision. For those valuing precision above all, the COSC accreditation provides peacefulness of mind, guaranteeing that each accredited watch will operate reliably under various circumstances. Whether for individual satisfaction or as an investment decision, COSC-certified watches stand out in the world of horology, bearing on a tradition of careful timekeeping.
