Unhealthy people tend to have high blood pressure. Fit & healthy people who exercise tend to have low blood pressure. My question is won’t athletes have B.P a bit higher than normal due to a heavy training load & the heart been stronger & possibly enlarged pumping a higher volume of blood than an average couch surfer? Also the general chart doesn’t take into account age, height, weight, profession, recently eaten & drank coffee, mental state etc. Isn’t it just like the BMI thing when super league players of solid muscle are classed as ‘obese’?
