Ausdauer ab 55: Bremst Fitness, dass sich Krankheiten ansammeln?

<h4>Background</h4>Cardiorespiratory fitness (CRF) has been linked to lower risk of individual chronic diseases, but little is known about the CRF in relation to multimorbidity.<h4>Objectives</h4>The authors investigated the association between CRF and multimorbidity risk and explored differences in the trajectories of chronic disease accumulation at varying levels of CRF.<h4>Methods</h4>The study included 38,348 adults from the UK Biobank (mean age 55.21 ± 8.15 years; 51.95% female) who were followed for up to 15 years to detect the incidence of 59 common chronic diseases. CRF was estimated using a 6-minute submaximal exercise test and tertiled as low, moderate, and high (after standardization by age and sex). Multimorbidity was defined as the presence of 2 or more chronic diseases. Data were analyzed using Cox regression, Laplace regression, and linear mixed-effects models.<h4>Results</h4>During the follow-up (median [IQR]: 11.57 [7.39-11.76] years), 15,368 (40.08%) participants developed multimorbidity. The risk of multimorbidity was 21% lower in participants with high compared to low CRF (HR: 0.79 [95% CI: 0.76-0.83]). The median time to multimorbidity onset was 1.27 (95% CI: 1.01-1.54) years later for those with high compared to low CRF. Moreover, participants with high CRF experienced a significantly slower annual rate of chronic disease accumulation (β = -0.043 [-0.050 to -0.036]).<h4>Conclusions</h4>High CRF is associated with lower multimorbidity risk, delayed onset

<h4>Objective</h4>To evaluate the association of estimated cardiorespiratory fitness (eCRF) with incident cardiometabolic multimorbidity (CMM) and its potential contribution to CMM risk prediction in an older adult population.<h4>Patients and methods</h4>The analysis included 3326 participants from the English Longitudinal Study of Aging (mean age 63 years; 1820 (54.7%) women) who were free of hypertension, cardiovascular disease, diabetes, and stroke at baseline (wave 4; 2008-2009). Estimated CRF was derived using validated nonexercise prediction equations (heart rate-based, body mass index-based, and Nord-Trøndelag Health Study-based eCRF). Incident CMM was defined at wave 10 (2021-2023) as the presence of ≥2 of the following: hypertension, cardiovascular disease, diabetes, or stroke. Multivariable-adjusted odds ratios (ORs) (95% CIs) and discrimination indices were calculated.<h4>Results</h4>During 12-15 years of follow-up, 197 (5.9%) participants developed CMM. Each eCRF measure reported an inverse linear association with CMM risk. Higher heart rate-based eCRF was associated with lower odds of CMM (per 1- metabolic equivalents (MET) increment: OR=0.78; 95% CI, 0.70-0.87; highest vs lowest tertile: OR=0.42; 95% CI, 0.25-0.69). Similar associations were observed for body mass index-based eCRF (per 1-MET increment: OR=0.78; 95% CI, 0.68-0.89; highest vs lowest tertile: OR=0.42; 95% CI, 0.25-0.70) and Nord-Trøndelag Health Study-based eCRF (per 1-MET increment: OR=0.73; 95% C

BACKGROUND: Non-communicable diseases (NCDs) account for an estimated 80% of the healthcare burden among older adults globally. Aerobic physical activity (PA) contributes to functional mobility, increased bone and muscle strength, prevention of illness and quality of life; however, PA is not yet a fully realised aspect of geriatric care. OBJECTIVE: To review recent evidence for the impact of aerobic PA and cardiorespiratory fitness (CRF) on mortality and NCD outcomes in adults aged ≥ 65 years. METHODS: Following PRISMA guidelines, we performed a systematic search of the Scopus, Cochrane Library, PubMed and Web of Science databases, published between 2016 and February 2024. RESULTS: The 94 included studies (reported in 104 individual manuscripts) included 46 cross-sectional, 24 longitudinal, 7 cross-sectional/longitudinal, 1 intervention/cross-sectional, and 16 interventions studies. PA and CRF were consistently associated with reduced all-cause mortality in longitudinal studies. Most included studies reported inverse associations between measures of PA and cardiovascular disease (CVD, n = 14 of 16 studies) risk and measures of dysglycaemia (n = 12 of 16 studies). Obesity/adiposity, blood pressure, lipids, and metabolic syndrome (MetS) were not consistently associated with aerobic PA. While aerobic PA interventions generally improved depression outcomes, longitudinal studies showed inconclusive results. Observational evidence suggests an association between PA and frailty, but
