The fact that women usually outlive men is the subject of study for centuries not only years.
According to the researches power of the male heart is less for 20-25% between the ages 18-70. But the data shows that in the case of women health women’s heart at the age of 70 can function like the heart of 20 years-old.
LJMU research studied 250 healthy men women between the ages of 18-80. The main purpose of choosing only healthy candidates was determined by the fact that it would have been easier to make decisions and conclusions about the study that reveals the results giving opportunities to evaluate the data.
Professor Goldspink says: "By simultaneously studying both men and women we have been able to look for either similarities or differences between the two sexes as we get older. We now have a much clearer holistic picture of changes that take place in the human body throughout our life cycle."
Research finds that men can improve the indicators of the results by increasing regular exercising as it is clear with the veterans that their heart condition at the age of 50-70 is like it was in their 20-ies.
· Each volunteer taking part in the ageing and cardiovascular system research underwent five hours of non-invasive tests, focusing on three key aspects of our cardiovascular system.
· First, Tom Reilly, Director of LJMU’s Research Institute for Sports & Exercise Sciences, and his team measured body composition to establish bone density, muscle mass and the amount and distribution of body fat in each individual.
· Then Professor Goldspink’s team measured blood pressure, how fit each person was and in particular how powerful their hearts were at rest and when exercising to their limits on a treadmill.
· During the final phase of tests, heart performance was measured. Dr Keith George used ultrasound to measure the size of the chambers of the heart, the thickness of its muscular walls and its filling and emptying actions. Professor Tim Cable’s team studied the movement of blood out of the heart through the arteries to the muscles and skin of the limbs.
· The resulting information has produced a very detailed picture on the changes that occur in the cardiovascular system as we age naturally and shows that men and women experience a lot of similar changes as they get older:
o Most men and women become less active and less fit as they grow older, reducing muscle mass and increasing the amount of body fat.
o Blood pressure increases both at rest and during exercise, because the large arteries become stiffer and less elastic as we age.
o Blood flow to the muscles and skin of limbs also progressively decrease. These changes in the structure of blood vessels occur earlier in men, but women soon catch up after the menopause.
According to Science Daily, Kruger and co-author Randolph Nesse, a professor of psychology and psychiatry and director of the Evolution and Human Adaptation Program, argue that the difference in life expectancy stems from the biological imperative of attracting mates. "This whole pattern is a result of sexual selection and the roles that males and females play in reproduction," Kruger said, "Females generally invest more in offspring than males and are more limited in offspring quantity, thus males typically compete with each other to attract and retain female partners." Scientists think that determining impact has the social status of a man, too.
But except serious findings of the research there are some funny approaches to this issue. The photos say why men live less than women. You can have a fun.
