P\u0159i v\u00fdb\u011bru nov\u00e9 rakety je nejd\u016fle\u017eit\u011bj\u0161\u00ed neztratit hlavu. Nestarat se o to, jakou m\u00e1 barvu, kdo j\u00ed vyrobil anebo kter\u00fd hr\u00e1\u010d z TOP 20 s n\u00ed hraje. Nejd\u016fle\u017eit\u011bj\u0161\u00edm krit\u00e9riem je, zda s n\u00ed m\u016f\u017ee hr\u00e1\u010d zlep\u0161it svou hru, v opa\u010dn\u00e9m p\u0159\u00edpad\u011b to pro n\u011bj nen\u00ed vhodn\u00e1 raketa. Aby hr\u00e1\u010di m\u011bli z tenisu v\u011bt\u0161\u00ed radost, mus\u00ed se zlep\u0161ovat. Je jedno jestli v\u00edt\u011bz\u00ed na turnaj\u00edch nebo prost\u011b z\u00edsk\u00e1vaj\u00ed hern\u00ed jistotu p\u0159i pravideln\u00e9m tr\u00e9ninku. Ale co zlep\u0161\u00ed hru? V\u00edce s\u00edly? V\u00edce kontroly? V\u011bt\u0161\u00ed ovladatelnost d\u00edky n\u00ed\u017e je hr\u00e1\u010d na s\u00edti pohotov\u011bj\u0161\u00ed? Nebo v\u00edce komfortu, kter\u00fdm p\u0159edch\u00e1z\u00ed zran\u011bn\u00edm? Nen\u00ed od v\u011bci vysv\u011btlit, co se obecn\u011b pova\u017euje za hlavn\u00ed, hru zlep\u0161uj\u00edc\u00ed, hern\u00ed krit\u00e9ria:<\/p>\n

Stabilita
\nUkazatel, kter\u00fd ur\u010duje, jak se raketa zachov\u00e1, kdy\u017e hr\u00e1\u010d m\u00ed\u010d odehraje mimo st\u0159ed plochy rakety. Obecn\u011b plat\u00ed, \u017ee rakety s v\u011bt\u0161\u00ed \u00faderovou plochou jsou m\u00e9n\u011b n\u00e1chyln\u00e9 ke zkrut\u016fm a deformac\u00edm p\u0159i \u00faderu.<\/p>\n

Komfort
\nV\u00fdrobci raket se p\u0159edh\u00e1n\u011bj\u00ed v tom, kdo ve sv\u00fdch raket\u00e1ch zabuduje v\u011bt\u0161\u00ed v\u00fdb\u011br p\u0159\u00edslu\u0161enstv\u00ed, kter\u00e9 zabra\u0148uj\u00ed anebo tlum\u00ed n\u00e1razy a vibrace. Do t\u00e9to kategorie lze za\u0159adit technologii Twin-Tube od Headu nebo Power-holes Wilsonu.<\/p>\n

S\u00edla
\nRakety, kter\u00e9 produkuj\u00ed v\u00edce s\u00edly maj\u00ed v\u011bt\u0161inou \u0161ir\u0161\u00ed a tu\u017e\u0161\u00ed r\u00e1m, jsou del\u0161\u00ed, maj\u00ed v\u011bt\u0161\u00ed hlavu, a jsou vyv\u00e1\u017een\u00e9 do hlavy. Jsou ur\u010deny pro hr\u00e1\u010de, kte\u0159\u00ed pot\u0159ebuj\u00ed zahr\u00e1t tvrd\u011bji, aby jejich norm\u00e1ln\u00ed, b\u011b\u017en\u00fd \u00fader dolet\u011bl a\u017e k z\u00e1kladn\u00ed \u010d\u00e1\u0159e. Nejlep\u0161\u00ed hr\u00e1\u010di s tvrd\u00fdmi \u00fadery, jako je t\u0159eba Pete Sampras, produkuj\u00ed vlastn\u00ed s\u00edlu a proto kdyby si je\u0161t\u011b nav\u00edc vzali tento typ rakety, m\u011bli by pot\u00ed\u017ee zahr\u00e1t m\u00ed\u010d do dvorce. Proto tak\u00e9 profesion\u00e1ln\u00ed hr\u00e1\u010di obvykle hraj\u00ed s raketami, kter\u00e9 tolik s\u00edly sami o sob\u011b neprodukuj\u00ed.<\/p>\n

Kontrola
\nPro vysp\u011bl\u00e9 hr\u00e1\u010de znamen\u00e1 kontrola p\u0159esnost, schopnost zahr\u00e1t m\u00ed\u010d do ur\u010dit\u00e9ho m\u00edsta na dvorci. Pro n\u011b jsou vhodn\u00e9 rakety s lep\u0161\u00ed kontrolou, tak aby mohli “c\u00edtit” m\u00ed\u010d na raket\u011b. To jsou obvykle rakety s u\u017e\u0161\u00edm r\u00e1mem, kter\u00e9 je mo\u017en\u00e9 p\u0159i \u00faderu prot\u00e1hnout d\u00e1le, zlep\u0161it dotek m\u00ed\u010de s raketou a neztratit p\u0159itom kontrolu.
\nPro st\u0159edn\u011b pokro\u010dil\u00e9 hr\u00e1\u010de to znamen\u00e1 mo\u017enost dobr\u00e9ho kontaktu m\u00ed\u010de s v\u00fdpletem, mo\u017enost udr\u017eet m\u00ed\u010d ve h\u0159e a pokra\u010dovat ve v\u00fdm\u011bn\u011b. Pro takov\u00e9 hr\u00e1\u010de jsou nejvhodn\u011bj\u0161\u00ed rakety se \u0161ir\u0161\u00edm r\u00e1mem, v\u011bt\u0161\u00ed \u00faderovou plochou a del\u0161\u00edm dr\u017eadlem.<\/p>\n

U ka\u017ed\u00e9 rakety je v\u017edy jedno z t\u011bchto krit\u00e9ri\u00ed p\u0159evl\u00e1daj\u00edc\u00ed. Mus\u00ed u n\u00ed b\u00fdt v\u0161ak obsa\u017eena i ta zb\u00fdvaj\u00edc\u00ed krit\u00e9ria a \u017e\u00e1dn\u00e9 nem\u016f\u017ee chyb\u011bt. Samotn\u00e1 s\u00edla by byla na nic, pokud by hr\u00e1\u010d nezahr\u00e1l m\u00ed\u010d do dvorce; raketa, kter\u00e1 p\u0159i \u00faderu vyd\u00e1v\u00e1 v\u011bt\u0161\u00ed svist ne\u017e skibob na dr\u00e1ze by asi tak\u00e9 nest\u00e1la za jist\u00e9 zran\u011bn\u00ed ruky.<\/p>\n","protected":false},"excerpt":{"rendered":"
