Cardiorespiratory Fitness in the Obesity Paradox.

 

There is not astonishment to find out that being obese leads to further health complications.

​

Obesity is a major risk for the development of cardiovascular disease. It plays a big part in heart disease, by increasing the likelihood of developing diabetes, hypertension and high cholesterol.

Obesity and low cardiorespiratory fitness (CRF) have been shown to independently increase the risk of CVD mortality.

Furthermore, Long-term prospective studies have found both CRF and obesity to be strong predictors of CV mortality. Some evidence suggests that CRF may be a more influential moderator of CV risk than obesity because the influence of obesity is reduced or negated with high CRF.

​

There is general consensus found across several different studies that the obesity paradox persists among patients with low CRF. "However, among patients with high CRF, risk of all-cause mortality is lowest for the overweight category in some, but not all, studies, suggesting that higher levels of fitness may modify the relationship between body fatness and survival in patients manifesting an obesity paradox."
