Aerobic training protects cardiac function during advancing age: a meta-analysis of four decades of controlled studies

In contrast to younger athletes, there is comparatively less literature examining cardiac structure and function in older athletes. However, a progressive accumulation of studies during the past four decades offers a body of literature worthy of systematic scrutiny. We conducted a systematic review, meta-analysis and meta-regression of controlled echocardiography studies comparing left ventricular (LV) structure and function in aerobically trained older athletes (> 45 years) with age-matched untrained controls, in addition to investigating the influence of chronological age. statistic. , 95% CI 0.05-1.86, p = 0.04). Meta-regression for chronological age identified that athlete-control differences, in the main, are maintained during advancing age. Athletic older men have larger cardiac dimensions and enjoy more favourable cardiac function than healthy, non-athletic counterparts. Notably, the athlete groups maintain these effects during chronological ageing

Cardiovascular Benefits of Endurance Training in Seniors:40 is not too Late to Start

International audienceIt is unknown whether commencing structured endurance training after 40 years of age is powerful enough to induce beneficial cardiovascular adaptations in later life. 34 men between the ages of 55 and 75 were included: 10 life-long sedentary seniors (SED), 13 endurance master athletes who commenced training≤30 years of age (ET30), and 11 endurance master athletes who commenced training≥40 years of age with no prior physical training (ET40). All performed resting 5-min spectral heart rate (HR) variability analysis, resting and submaximal-exercise echocardiography, and a maximal exercise test. Maximal oxygen uptake was higher and resting HR was lower in both trained groups vs. SED, without difference between ET30 and ET40. Atrial and left ventricle dimensions were greater in ET30 and ET40 vs. SED, without difference between both athletes groups. At rest, total arterial compliance was improved in both ET30 and ET40 compared to SED. During submaximal exercise, improvement in global LV afterload was only observed in ET30 vs. SED. Two powerful markers of health, maximal oxygen uptake and resting HR, did not differ between athletes who commenced training before 30 or after 40 years of age, but were significantly improved compared to their life-long sedentary counterparts

[Cognitive decline in geriatric oncology: Trends, evaluation and treatment]

International audienceCancer prevalence increases with aging. Prevalent or incident neurocognitive disorders are frequent in geriatric oncology. Cognitive decline associated with cancer increases the risk of under or over-cancer treatment and makes therapeutic decisions complex. In this context, we present tools to optimize cognitive impairment screening, identification of underlying mechanisms and specific treatments. Geriatric specialists intervention can help global care, social services utilization and patient's orientation when ambulatory cares become difficult
