    Default Αύξηση Οστικής Μάζας Σε Γυνάικες 70 Ετών Μέσω Προπόνησης Αντιστάσεων

    Το γνωριζαμε λιγο πολυ ηδη οτι η προπονηση με αντιστασεις εχει πολλα θετικα για ανθρωπους μεγαλυτερης ηλικιας.

    Η συγκεκριμενη μελετη εδειξε πως προπονηση με αντιστασεις σε γυναικες που ειχαν μειωμενη μυικη δυναμη, 3 φορες την εβδομαδα για 60 λεπτα, ειχε ως αποτελεσμα βελτιωση της οστικης μαζας των γοφων κατα 6%!!

    Ως συμπερασμα μπορουμε να πουμε πως προπονηση αντιστασεων με ασφαλεια εχει θετικα αποτελεσματα στην προληψη οστεοπορωτικων καταγματων σε γηραιοτερες γυναικες με μειωμενη μυικη δυναμη.

    Huovinen V, et al, Bone mineral density is increased after a 16-week resistance training intervention in elderly women with decreased muscle strength. Eur J Endocrinol. 175(6):571-582. 2016. Turku University. Finland

    Abstract

    OBJECTIVE: Non-pharmacological interventions are important in reducing risk for osteoporotic fractures. We investigated the effects of a 16-week individualized resistance training intervention on bone mineral density (BMD), bone turnover markers and 10-year relative risk (RR) for osteoporotic fracture.

    DESIGN: Interventional study with a follow-up.

    METHODS: In total, 37 elderly women (mean age 71.9 ± 3.1 years) with decreased muscle strength participated in the resistance training intervention three times per week with 60 min per session for 16 weeks under the supervision of a licensed physiotherapist. Total hip BMD with
    quantitative CT, bone markers (sclerostin, osteocalcin, CTX, PINP, IGF-1, 25(OH)-D) and 10-year RR for osteoporotic fracture were measured at baseline, post-intervention and at 1-year follow-up after the end of the intervention. Eleven age- and sex-matched controls did not participate in the intervention but were studied at baseline and at 1-year follow-up.

    RESULTS:Resistance training seemed to increase total hip BMD by 6% (P = 0.005). Sclerostin (P < 0.001) and total osteocalcin (P = 0.04) increased while other bone markers remained unchanged. A 10-year RR for major osteoporotic and hip fracture remained unchanged. At follow-up total
    hip BMD (P < 0.001) decreased back to the baseline level with a simultaneous decrease in serum sclerostin (P = 0.045), CTX (P < 0.001) and an increase in 25(OH)-D (P < 0.001), 10-year RR for major osteoporotic (P = 0.002) and hip fracture (P = 0.01).

    CONCLUSIONS:Our findings suggest an important role of continuous supervised resistance training for the prevention of osteoporotic fractures in elderly women with decreased muscle strength.

    Αυτό είναι δεδομένο! Η συστηματική γυμναστική με αντιστάσεις ειναι σωτήρια σε αυτές τις ηλικίες! Εχω δει πολλές φορές στο γυμναστήριο γυναίκες 70+ να κάνουν ασκήσεις.

    Χαίρομαι που το διαβάζω σε μελέτη. Επιβεβαιώνει τα λεγόμενα του προσωπικού μου ιατρού, πως με τη συστηματική εκγύμναση με αντιστάσεις δεν εμφανίζονται θέματα οστεοπόρωσης.
