Researchers compared 33 060 runners and 15945 walkers to investigate the effect of differences in exercise type and intensity on CHD risk factors. The initial expenditure (METhr / day) was compared with the hypertension, hypercholesterolemia, diabetes and coronary artery disease detected by the physician during the 6.2 years of follow-up.
Running has reduced the risk
One MET determines the consumption of one kilocalorie of energy for one kilogram of body weight in one hour of rest (quiet sitting) (kcal / kg / h) and the number of MET means how many times more energy is consumed during exercise compared to the energy spent in rest time. Very slow walk (<3 km / h) is a small physical activity, referred to as 2 MET, free walk (3 km / h) – 2.5 MET. A moderate level of physical activity is in the 3-6 MET range, eg a fast walk (6 km / h) – 3 MET, recreational skiing – 5 MET, cycling at 15-18 km / h or medium intensity classes fitness – 6 MET. Intense physical activity is a 7-12 MET energy expenditure, e.g. tennis (singles) or running at 8 km / h – 8 MET, swimming (crawl) – 10 MET, running (12 km / h) – 12 MET.
The application of running does not bring significantly higher results compared to walking in the case of risk of diabetes or coronary heart disease, while walking has been more effective in the case of hypertension and hypercholesterolemia. It is therefore best to combine both forms of activity.
