G\u0142\u00f3wnym mitem pokutuj\u0105cym od lat w medycynie i teorii treningu jest teza o rzekomym zahamowaniu wzrostu u \u0107wicz\u0105cych oporowo dzieci. Wed\u0142ug niej trening si\u0142owy mia\u0142 uszkadza\u0107 chrz\u0105stki wzrostowe znajduj\u0105ce si\u0119 w nasadach ko\u015bci. Wraz z post\u0119pem wiedzy przeanalizowano te badania, udowadniaj\u0105c, \u017ce programy treningowe w nich przedstawione nie by\u0142y dostosowane do mo\u017cliwo\u015bci m\u0142odocianych oraz \u0107wicz\u0105cy nie posiadali wiedzy na temat poprawnej techniki \u0107wicze\u0144 (czyli trenowali bez odpowiedniego nadzoru). Co ciekawe, okazuje si\u0119, \u017ce wi\u0119ksze ryzyko uszkodzenia chrz\u0105stek wzrostowych pojawia\u0142o si\u0119 przy r\u00f3\u017cnego rodzaju wyskokach i l\u0105dowaniach z zeskoku.<\/p>\n\n\n\n

Dodatkowym b\u0142\u0119dem metodologicznym bada\u0144 z minionych lat by\u0142o to, \u017ce kwalifikowano do udzia\u0142u w nich m\u0142odzie\u017c nieuprawiaj\u0105c\u0105 innych sport\u00f3w poza podnoszeniem ci\u0119\u017car\u00f3w (w kolebkach tej dyscypliny takich jak Bu\u0142garia czy Turcja) \u2013 a tu dob\u00f3r naturalny do tego sportu preferowa\u0142 osobnik\u00f3w niskich, kr\u0119pych, u kt\u00f3rych tempo wzrastania nie by\u0142o por\u00f3wnywalne z innymi populacjami. Na podstawie obecnie dost\u0119pnej wiedzy eksperci sformu\u0142owali tez\u0119, \u017ce trening oporowy (trening si\u0142owy) nie powoduje ubytk\u00f3w w p\u0142ytkach wzrostowych i nie spowalnia procesu wzrostu<\/strong>.<\/span><\/p>\n\n\n\n

Wed\u0142ug prawa Delpeche\u2019a i Wolffa obci\u0105\u017canie tkanki kostnej jest jednym z g\u0142\u00f3wnych czynnik\u00f3w stymuluj\u0105cych jej tworzenie. Dlatego g\u0119sto\u015b\u0107 ko\u015bci nastolatk\u00f3w, \u0107wicz\u0105cych zgodnie z bezpiecznymi zasadami d\u017awigania ci\u0119\u017car\u00f3w, jest 20-35% wi\u0119ksza ni\u017c \u015brednia dla ich wieku. I odwrotnie – wyeliminowanie tych si\u0142 prowadzi do zaniku ko\u015b\u0107ca – tak jak ma to miejsce np. u os\u00f3b trwale le\u017c\u0105cych lub kosmonaut\u00f3w. To samo prawo m\u00f3wi, \u017ce prawid\u0142owy wzrost ko\u015bci mo\u017ce nast\u0105pi\u0107 jedynie pod warunkiem dzia\u0142ania r\u00f3wnomiernie roz\u0142o\u017conych si\u0142 nacisku i poci\u0105gania, dlatego nacisk na technik\u0119 \u0107wicze\u0144 pozostaje niebagatelny.<\/p>\n\n\n\n

Trening oporowy (trening si\u0142owy) prowadzony przed okresem dojrzewania kszta\u0142tuje g\u0142\u00f3wnie rozw\u00f3j si\u0142y<\/strong>, przede wszystkim dzi\u0119ki mechanizmom dzia\u0142aj\u0105cym w obr\u0119bie uk\u0142adu nerwowego, kt\u00f3re zwi\u0119kszaj\u0105 liczb\u0119 motoneuron\u00f3w generuj\u0105cych impulsy przy ka\u017cdym skurczu mi\u0119\u015bni. Zwi\u0119kszenie si\u0142y u dzieci mo\u017cna uzyska\u0107 bez wzrostu masy mi\u0119\u015bniowej.<\/strong> Do przerostu mi\u0119\u015bni niezb\u0119dne jest pojawienie si\u0119 androgen\u00f3w, co zaistnieje dopiero przy pokwitaniu.<\/p>\n\n\n\n

Niezale\u017cnie od uczestnictwa w innych aktywno\u015bciach sportowych, w okresie m\u0142odzie\u0144czym aktywno\u015b\u0107 taka jest ch\u0119tniej stosowana w celu zwi\u0119kszenia masy mi\u0119\u015bniowej. Hiperplazja (wzrost ilo\u015bci w\u0142\u00f3kien mi\u0119\u015bniowych) przebiega w najwi\u0119kszej mierze w\u0142a\u015bnie w okresie pokwitania.
