Et s\u00fcda p\u00fcsiks terve ja tugev, v\u00f5ib kasuks tulla kehaline liikumine. Brasiilia teadlaste uurimist\u00f6\u00f6 p\u00f5hjal on selgunud, et ujumine on s\u00fcdame tugevdamisel t\u00f5husam kui jooksmine, v\u00e4hemalt n\u00e4rilistel.<\/p>\n

On juba teada, et nii ujumisest kui ka jooksmisest, kui neid \u00f5igesti teha ja mitte \u00fcle pingutada, v\u00f5ib s\u00fcdame tervisele kasu t\u00f5usta.<\/p>\n

Andrey Jorge Serra S\u00e3o Paulo F\u00f6deraal\u00fclikoolist ja ta kolleegid soovisid aga l\u00e4hemalt v\u00e4lja uurida, kumb neist kahest sportimisviisist see k\u00f5ige t\u00f5husam on. Selleks tegid nad katseid rottide peal.<\/p>\n

Rotid jagati kolme r\u00fchma. \u00dcks r\u00fchm ei teinud \u00fcldse trenni, teine pandi viiel p\u00e4eval n\u00e4dalas tunniks ajaks jooksma ja kolmas ujuma, kokku kaheksa n\u00e4dalat.<\/p>\n

Selleks, et jooksmise ja ujumise kui erisuguste liikumisviiside intensiivsust v\u00f5rrelda, m\u00f5\u00f5tsid teadlased rottide hapnikutarvitust.<\/p>\n

<\/p>\n

Selgus, et nii jooksjatel kui ka ujujatel rottidel oli viimase trenni ajaks hapniku tarbimise t\u00f5husus esimese trenniga v\u00f5rreldes kasvanud \u00fcle viie protsendi.<\/p>\n

Kuid ainult ujujatel oli s\u00fcdames n\u00e4ha ka olulisi struktuurimuutusi. Neil oli suurenenud kogu s\u00fcdame mass, eelk\u00f5ige aga vasaku vatsakese mass. Jooksutrenni teinud rottidel p\u00fcsis s\u00fcdamemass \u00fcsna samasugune kui trenni \u00fcldse mitte teinud rottidel.<\/p>\n

Teadlased uurisid ka nende s\u00fcdamemuutuste ehk s\u00fcdame f\u00fcsioloogilise h\u00fcpertroofiaga seotud geenide aktiivsust ja valgus\u00fcnteesi. Ka neis n\u00e4itajais oli ujumisega tegelnud rottidel m\u00e4rgata suuremaid muutusi kui jooksurottidel.<\/p>\n

Tulemused on nad n\u00fc\u00fcd avaldanud ajakirjas Scientific Reports<\/a>.<\/p>\n

Teadlased m\u00e4rgivad, et ujumisel v\u00f5ib olla eriline toime ka s\u00fcdamelihase taastumisele.<\/p>\n

Uutest teadmistest on kasu teaduselegi, sest n\u00fc\u00fcd on v\u00f5imalik ujumise ja jooksmise f\u00fcsioloogilist m\u00f5ju paremini \u00fcksteisest eristada. Seni ei ole kehalise liikumise vormide erinevusi sedalaadi uuringuis nende s\u00f5nul alati vajaliku selgusega arvesse v\u00f5etud.<\/p>\n

Praeguses uuringus said s\u00fcdame struktuuri muutusi korraldavad molekulaarsed mehhanismid ka \u00fcle\u00fcldse natuke selgemaks kui enne.<\/p>\n

Inimesed valivad spordiala suuresti isiklikest eelistustest ja v\u00f5imetest l\u00e4htuvalt, kuid kui rottkatsete tulemusi \u00f5nnestub edaspidi ka inimestele laiendada, saab spordiala valida selle v\u00f5rra teadlikumalt.<\/p>\n
