Ara\u015ft\u0131rman\u0131n en dikkat \u00e7ekici bulgusu, “beynin g\u00fcbresi” olarak tan\u0131mlanan BDNF (beyin t\u00fcrevli n\u00f6rotrofik fakt\u00f6r) kimyasal\u0131 \u00fczerinde oldu. 12 hafta boyunca d\u00fczenli bisiklet s\u00fcren grupta, bu kimyasal\u0131n seviyelerinde ciddi bir y\u00fckseli\u015f g\u00f6zlendi. BDNF, beyindeki n\u00f6ronlar\u0131n b\u00fcy\u00fcmesini sa\u011flarken, h\u00fccreler aras\u0131 ileti\u015fimi de g\u00fc\u00e7lendiriyor.

Ayr\u0131ca uyku kalitesini art\u0131rmak, sa\u011fl\u0131kl\u0131 bir beslenme d\u00fczeni benimsemek ve kardiyovask\u00fcler risk fakt\u00f6rlerini y\u00f6netmek de beyin h\u00fccrelerinin korunmas\u0131nda kritik rol oynuyor.<\/p>\n\n\n\n
