Fare poco o scarso esercizio fisico influenzerebbe i rischi di mortalità molto più degli altri fattori, come diabete, fumo o ipertensione. È la conclusione di uno studio retrospettivo della Cleveland University che ha definito il fenomeno "bassa fitness cardio-respiratoria" ed ha stupito gli stessi autori: la ricerca ha rivisto i dati raccolti tra il 1991 ed il 2014 dai test sotto sforzo fatti a circa 122'000 persone tra i 53 ed i 73 anni.
La pigrizia uccide

"Non abbiamo mai visto qualcosa di così pronunciato - ha detto il cardiologo leader della ricerca - essere decisamente fuori forma ha evidenziato un effetto peggiore sulla longevità della pressione alta, del diabete e dell'uso di sigarette". Le persone più sedentarie e poco capaci di resistere al test sotto sforzo rispetto a quelle al top delle capacità e più atletiche, hanno mostrato rischi di mortalità persino tre volte più alti rispetto ai fumatori. Anche per chi ha una forma fisica media, ma non pessima, i rischi di mortalità sono risultati decisamente più elevati rispetto ai super atleti.
