Svaly jsou z\u00e1kladem pro n\u00e1\u0161 aktivn\u00ed pohyb. Jsou dvoj\u00edho typu. Hladk\u00e1 svalovina a p\u0159\u00ed\u010dn\u011b pruhovan\u00e1. Hladkou svalovinu bychom na\u0161li v r\u016fzn\u00fdch vnit\u0159n\u00edch org\u00e1nech, nap\u0159\u00edklad v tr\u00e1vic\u00ed trubici nebo mo\u010dov\u00e9m m\u011bch\u00fd\u0159i.Ta je neovladateln\u00e1 v\u016fli a moc se o n\u00ed mezi lidmi nemluv\u00ed. P\u0159\u00ed\u010dn\u011b pruhovan\u00e1 svalovina je upevn\u011bna na kost\u0159e pomoc\u00ed \u0161lach a jej\u00edm hlavn\u00edm \u00fakol je pr\u00e1v\u011b pohyb cel\u00e9ho t\u011bla.

Svaly jsou tvo\u0159en\u00e9 svalov\u00fdmi vl\u00e1kny, jednotliv\u00fdmi bu\u0148kami. V t\u011bchto bu\u0148k\u00e1ch se nach\u00e1z\u00ed velk\u00e9 mno\u017estv\u00ed speci\u00e1ln\u00edch protein\u016f, kter\u00e9 se um\u00ed kontrahovat, p\u0159i\u010dem\u017e zaji\u0161\u0165uj\u00ed svalovou aktivitu. Na\u0161e svaly ale nejsou dobr\u00e9 jen k pohybu. Sv\u00fdm metabolismem se zapojuj\u00ed do chodu cel\u00e9ho organismu. Nap\u0159\u00edklad pr\u00e1v\u011b svaly jsou t\u00edm org\u00e1nem, kter\u00fd spot\u0159ebov\u00e1v\u00e1 velk\u00e9 mno\u017estv\u00ed gluk\u00f3zy. Tuto gluk\u00f3zu jsou schopn\u00e9 p\u0159ij\u00edmat ale jen v moment\u011b, kdy na n\u011b p\u016fsob\u00ed inzulin. Pokud ale dlouhodob\u011b p\u0159et\u011b\u017eujeme slinivku, kter\u00e1 tvo\u0159\u00ed inzulin, p\u0159\u00edli\u0161n\u00fdm p\u0159\u00edjmem gluk\u00f3zy, p\u0159estane m\u00edt schopnost tolik inzulinu produkovat. Svaly tak nejsou schopn\u00e9 gluk\u00f3zu p\u0159ij\u00edmat a doch\u00e1z\u00ed ke vzniku cukrovky II. typu. A toto v\u0161e je jen zlomek. Mus\u00edme se tak sna\u017eit, aby na\u0161e svaly rostly, mus\u00edme sportovat. Nyn\u00ed, kdy\u017e p\u0159ich\u00e1z\u00ed zimn\u00ed obdob\u00ed, je to n\u00e1ro\u010dn\u011bj\u0161\u00ed. Ale s dobr\u00fdm vybaven\u00edm jde v\u0161echno. Nap\u0159\u00edklad Didrikson kure je oble\u010den\u00ed, kter\u00e9 m\u016f\u017eete vyu\u017e\u00edt v\u017edy a nikdy V\u00e1s nezklame. Sta\u010d\u00ed jen jednou vyzkou\u0161et a pak u\u017e se jej nikdy nebudete cht\u00edt vzd\u00e1t.
