Although moderate and light physical activity (for example, walking) is undoubtedly beneficial to health, nevertheless, it does not protect against premature cardiovascular death. For the latter, more substantial loads are required - swimming, tennis and t.

This is reported in the May issue of Heart by Dr. John Yarnell and his colleagues (University of Queens, Belfast, Northern Ireland). They determined the optimal intensity of physical activity in a population of more than 1900 men aged 49-64 years. When included in the project The Caerphilly Study (1971 g. ), none of the participants did not suffer from cardiovascular diseases, according to the Internet edition for girls and women from 14 to 35 years old Pannochka. net During the 10 years of observation, 252 men (13%) died. More than 75% of these deaths were associated with heart disease.

The total time of exercise was directly related to overall, cardiovascular mortality and mortality from coronary artery disease, "the authors write. Only a heavy, intensive load (climbing stairs, swimming, jogging) was reliably and independently associated with a reduction in the risk of premature cardiovascular mortality.

Easy (walking, bowling, sailing) and moderate loading (golf, digging up beds, dancing).

It turned out that the intensity of the load is more important in this case than the total number of calories spent.

Men who routinely engaged in physical heavy workload but who did not spend more than 54 kcal / d (9 minutes of jogging or paired tennis, 7 minutes of climbing stairs) had a 47% lower risk of overall mortality and 63% lower risk of coronary death in the next 10 years.

On the contrary, among men who regularly engaged in light and moderate exercise and spent about 343 kcal / d (more than 90 minutes of walking, or 1 hour of ballroom dancing), the risk of premature death did not decrease.
