Beaumont AJ, et al. – Researchers of this systematic review, meta-analysis, and meta-regression of controlled echocardiography studies compared left ventricular (LV) structure and function in aerobically trained older athletes (aged > 45 years) with age-matched untrained control individuals, and studied the effect of chronological age. For this investigation, researchers searched electronic databases from inception to January 2018 before conducting a random-effects meta-analysis to calculate pooled differences in means, effect size, and 95% confidence intervals. They found that athletes had greater LV end-diastolic diameter, interventricular septal thickness, posterior wall thickness, LV mass, LV mass index, and stroke volume. Findings suggested that older athletic men have larger cardiac dimensions and enjoy more favorable cardiac function vs healthy non-athletic counterparts. They also identified that masters athletes maintain these effects during chronological ageing.
