One-way ANOVA or repeated measure ANOVA, where appropriate, was performed to detect statistical differences (&lt;/span&gt;&lt;em&gt;P&lt;/em&gt; &lt;!--&gt;&lt;&lt;!--&gt; &lt;!--&gt;0.05).&lt;/p&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Results&lt;/h3&gt;&lt;p&gt;Following the intervention, the Diabetes Self-care Scale (DSCS) scores in the control, CGM, and CGM&lt;!--&gt; &lt;!--&gt;+&lt;!--&gt; &lt;!--&gt;EX groups were 67.1&lt;!--&gt; &lt;!--&gt;±&lt;!--&gt; &lt;!--&gt;11.9, 84.8&lt;!--&gt; &lt;!--&gt;±&lt;!--&gt; &lt;!--&gt;19.3, and 112.7&lt;!--&gt; &lt;!--&gt;±&lt;!--&gt; &lt;!--&gt;10.9, respectively. These results indicated improvements in DSCS scores for both interventions, with the combined use of CGM and exercise demonstrating greater enhancement compared to CGM alone (CGM vs. CGM&lt;!--&gt; &lt;!--&gt;+&lt;!--&gt; &lt;!--&gt;EX, &lt;em&gt;P&lt;/em&gt; &lt;!--&gt;&lt;&lt;!--&gt; &lt;!--&gt;0.001). Notably, the combination of CGM and exercise was more effective in reducing 2-hour postprandial blood glucose values compared to the use of CGM alone (6.4&lt;!--&gt; &lt;!--&gt;±&lt;!--&gt; &lt;!--&gt;1.3 vs. 9.5&lt;!--&gt; &lt;!--&gt;±&lt;!--&gt; &lt;!--&gt;3.0, &lt;em&gt;P&lt;/em&gt; &lt;!--&gt;&lt;&lt;!--&gt; &lt;!--&gt;0.01).&lt;/p&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Conclusions&lt;/h3&gt;&lt;p&gt;These findings highlight the importance of combining CGM device with regular exercise into diabetes management to enhance self-care behaviors, maintain glycemic control, and reduce the risk of long-term complications associated with T2D.&lt;/p&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Objectifs&lt;/h3&gt;&lt;p&gt;&lt;span&gt;Face au fardeau socio-économique mondial que représente le DT2, il est nécessaire d’adopter des stratégies efficaces pour améliorer les comportements d’autosoins en vue d’une bonne gestion du diabète.

Thus, the objectives of this study were to systematically review the meta-analytic evidence verifying the effects of resistance training on muscular strength and/or hypertrophy in healthy adults and to address the quality of the meta-analytic evidence (CRD42020188928).&lt;/p&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;News&lt;/h3&gt;&lt;p&gt;Systematic reviews with meta-analyses that verified the effects of resistance training on strength and/or hypertrophy in healthy young adults, published in English, were searched in the PubMed, Web of Science, and Cochrane databases. The searches resulted in 1915 references, and 19 references were included following the adopted criteria. The selected meta-analyses investigated a total of 587 randomized controlled trials – 159 evaluated strength, 160 hypertrophy, and 268 both outcomes, involving 12,375 subjects of both sexes. Of the 19 selected meta-analyses, 31.6% verified the effect size of muscle strength, 31.6% of hypertrophy, and 36.8% of both variables (strength and hypertrophy). Moderate correlations were observed in the AMSTAR 2 quality assessment with the assessment of the quality of evidence (0.64; &lt;em&gt;P&lt;/em&gt; &lt;!--&gt;=&lt;!--&gt; &lt;!--&gt;0.003) and with the year of publication of the studies (0.57; &lt;em&gt;P&lt;/em&gt; &lt;!--&gt;=&lt;!--&gt; &lt;!--&gt;0.03).
