    Default Προπόνηση Με Βάρη & Αποτελεσματικότητα Στην Κατάθλιψη

    Νεα μετα-αναλυση απο 33 κλινικες δοκιμες, στις οποιες συμμετειχαν συνολικα 1877 ασθενεις, μας δειχνει πως η ασκηση με βαρη μειωνει σημαντικα τα καταθλιπτικα συμπτωματα.

    Ειναι κατι το οποιο εχει μελετηθει αρκετα σχετικα με την αεροβια ασκηση και γενικα την ασκηση, αλλα η συγκεκριμενη ερευνα επικεντρωθηκε στην προπονηση με αντιστασεις (με βαρη).

    Association of Efficacy of Resistance Exercise Training With Depressive Symptoms Meta-analysis and Meta-regression Analysis of Randomized Clinical Trials
    Brett R. Gordon, et al, JAMA Psychiatry. 2018;75(6):566-576.

    Question What is the overall association of efficacy of resistance exercise training with depressive symptoms, and which logical, theoretical, and/or prior empirical variables are associated with depressive symptoms?

    Findings In this meta-analysis of 33 clinical trials including 1877 participants, resistance exercise training was associated with a significant reduction in depressive symptoms, with a moderate-sized mean effect. Total volume of resistance exercise training, health status, and strength improvements were not associated with the antidepressant effect; however, smaller reductions in depressive symptoms were derived from trials with blinded allocation and/or assessment.

    Meaning The available empirical evidence supports resistance exercise training as an alternative and/or adjuvant therapy for depressive symptoms.

    ABSTRACT

    Importance The physical benefits of resistance exercise training (RET) are well documented, but less is known regarding the association of RET with mental health outcomes. To date, no quantitative synthesis of the antidepressant effects of RET has been conducted.

    Objectives To estimate the association of efficacy of RET with depressive symptoms and determine the extent to which logical, theoretical, and/or prior empirical variables are associated with depressive symptoms and whether the association of efficacy of RET with depressive symptoms accounts for variability in the overall effect size.

    Data Sources Articles published before August 2017, located using Google Scholar, MEDLINE, PsycINFO, PubMed, and Web of Science.

    Study Selection Randomized clinical trials included randomization to RET (n?=?947) or a nonactive control condition (n?=?930).

    Data Extraction and Synthesis

    Hedges d effect sizes were computed and random-effects models were used for all analyses. Meta-regression was conducted to quantify the potential moderating influence of participant and trial characteristics.

    Main Outcomes and Measures

    Randomized clinical trials used validated measures of depressive symptoms assessed at baseline and midintervention and/or postintervention. Four primary moderators were selected a priori to provide focused research hypotheses about variation in effect size: total volume of prescribed RET, whether participants were healthy or physically or mentally ill, whether or not allocation and/or assessment were blinded, and whether or not the RET intervention resulted in a significant improvement in strength.

    Results

    Fifty-four effects were derived from 33 randomized clinical trials involving 1877 participants. Resistance exercise training was associated with a significant reduction in depressive symptoms with a moderate-sized mean effect ? of 0.66 (95% CI, 0.48-0.83; z?=?7.35; P?<?.001). Significant heterogeneity was indicated (total Q?=?216.92, df?=?53; P?<?.001; I2?=?76.0% [95% CI, 72.7%-79.0%]), and sampling error accounted for 32.9% of observed variance. The number needed to treat was 4. Total volume of prescribed RET, participant health status, and strength improvements were not significantly associated with the antidepressant effect of RET. However, smaller reductions in depressive symptoms were derived from randomized clinical trials with blinded allocation and/or assessment.

    Conclusions and Relevance

    Resistance exercise training significantly reduced depressive symptoms among adults regardless of health status, total prescribed volume of RET, or significant improvements in strength. Better-quality randomized clinical trials blinding both allocation and assessment and comparing RET with other empirically supported treatments for depressive symptoms are needed.

It takes much more than physical strength for us to build and sculpt our bodies. It takes an enormous amount of mental strength as well, and that's what people are truly jealous of. Take it as a compliment, for you stand out in a crowd full of followers."

    Νομίζω πως αυτό ούτε καν χρειαζόταν να γίνει μετα-ανάλυση. Είναι δεδομένο το πόσο βοηθάνε τα βάρη στην ψυχολογία μας!
