Cardiorespiratory endurance definition12/31/2023 Erikssen and colleagues emphasize that even small improvements in CRF result in significant CVD risk reductions, which is a really an encouraging incentive to share with clients. It is important that exercise professionals inform their clients that by improving their fitness level they are actually developing healthier lives and reducing disease risk. (2010) cite other research that confirms improvement of low levels of CRF to moderate and high levels does reduce the risk of CVD and other causes of mortality decreases. The researchers report that improvements in CRF within the 7 years were associated with significant risk reduction from all causes of mortality. (1988) followed 2014 health men (40-60 years at baseline) for 7 years. With the risk of low levels of CRF to CVD well established, a meaningful question is whether improvements in CRF will also result in positive changes in CVD risk. Kodama and colleagues also clarify that this CVD risk reduction observed with higher CRF levels is present regardless of a person's age, sex, body mass index and smoking status.ĭoes a Change in CRF Affect Risk of Mortality? Persons with low CRF have a higher risk of all causes of mortality and CVD events, as compared to those individuals with moderate to high levels of CRF. From this analysis, Kodama and colleagues summarized that each 1-MET increase in CRF is associated with a 13% and 15% risk reduction from all-cause mortality and CVD events, respectively. (2009) reviewed 33 studies comprising 102,980 men and women participants (6910 all-cause deaths) and 84,323 participants (4485 CVD events). In a recent and original meta-analysis (study that combines results of several investigations) on CRF and mortality, Kodama et al. (2010) summarize several research studies that have demonstrated compellingly that moderate to high levels of CRF are associated with a reduced risk of CVD. This research column will review the new research examining the importance of CRF for CVD disease risk reduction. It is measured in milliliters of oxygen per kilogram of body weight (ml O2/kg/min). CRF can be defined as the ability of the respiratory, circulatory and muscular systems to consume, distribute and utilize oxygen during continuous physical activity (Lee et al.). Coinciding with these new AHA goals is new evidence suggesting that low cardiorespiratory fitness (CRF) is an equally strong predictor of cardiovascular disease (CVD) and other health causes of mortality (referred to as all-cause mortality), as are well-established risk factors such as smoking, obesity, hypertension and diabetes (Lee et al., 2010). The new Impact Goals document also declares that as the amount of physical activity increases through higher intensity, greater frequency, and/or longer duration, men and women experience much healthier lives. Ideal cardiovascular health includes four health behaviors (non-smoking, BMI <25 kg/m2, physical activity and three health factors (total cholesterol <200 mg/dL, fasting blood glucose <100 mg/dL, and <120/80 mmHG for blood pressure).
