Marginally significant improvements were observed in left ventricular ejection fraction (SMD\u00a0=\u00a00.19, 95% CI: 0.00 to 0.38, P\u00a0=\u00a00.05) and E\/e\u2019 ratio (SMD = \u22120.14, 95% CI: \u22120.29 to 0.00, P\u00a0=\u00a00.05).Subgroup analyses stratified by adherence to ACSM recommendations (\u226570% vs. &amp;lt;70%) showed that the high-adherence group achieved statistically greater improvements in 6-MWT (P\u00a0=\u00a00.03) and peak VO\n                      <jats:sub>2<\/jats:sub>\n                      (P\u00a0=\u00a00.003).
