4hw.com.cn: how to see whether a person has a long life? There are long eyebrows, high forehead, big earlobes, and lifeline of the palm. These signs come from facial features and life principles. At present, it is difficult to find a scientific basis. However, scientists have found that there are indeed three signs related to healthy longevity: heart rate, grip strength and vital capacity.
Heart rate: resting heart rate 55-60 times / min is the best
Some studies have compared the relationship between heart rate and life span in the elderly. It is found that the ratio of resting heart rate greater than 80 beats / min in men is nearly half lower than that of resting heart rate less than 60 beats / min in men who live to 85 years old. In other words, people who have a fast resting heart rate have a significantly increased risk of cardiovascular disease and a high mortality rate.
Since resting heart rate is the best at 55-60 beats per minute, is there any good way for the elderly to control it?
Here are three ways for you. The first is to exercise regularly, so that the heart function can be exercised; the second is to control weight, obesity will increase the burden on the heart, so that the heart rate can be accelerated; the third is to stop smoking and limit alcohol, because smoking and drinking can accelerate the resting heart rate.
Grip strength: proportional to heart function
Generally speaking, the grip strength often decreases with the aging of the body function, so we often say that the grip strength reflects the health of the body. In 2010, researchers from the British Medical Research Council found that those with the strongest grip usually lived longer than those with the weakest grip, and that those with the weakest grip had a 67% higher risk of death during the follow-up period than those with the strongest grip.
In addition to reflecting muscle strength, grip strength is proportional to our heart function. According to a Canadian study published in the lancet, poor grip strength indicates a higher risk of serious diseases such as heart disease and stroke, and a shorter life expectancy.
There are many ways to improve grip strength, and the method is very simple. Small instruments such as grip strength device are very convenient to be carried on the body and practiced at any time, not limited by time and space. In addition, there are also some fitness balls and leather balls that can help us to increase our grip strength. 'I have an oval pressure reducing ball myself, which has elasticity. In addition to reducing pressure, it can also help me to increase my grip strength. '
Of course, muscle strength can't be out of balance in exercise. Both the left and right hands need to do grip strength exercises. The elderly also need to exercise the muscle strength of the waist and legs when the safety is guaranteed. After all, whether the quality of life of the elderly can be guaranteed depends on the health of the whole body. Muscle strength is a very important indicator.
Vital capacity: large vital capacity, good body capacity
Vital capacity can predict life span, which is the conclusion of scientists from Boston University School of medicine after 30 years of research. Research shows that vital capacity is closely related to the functional capacity and metabolic capacity of various systems of the body. With the decrease of vital capacity, the capacity of internal organism also decreases.
To test the vital capacity, you can go to the hospital for a pulmonary function test. The middle-aged and elderly people can do this test to understand what their current vital capacity is, and better promote their own exercise.
The improvement of vital capacity mainly depends on the adherence to sports. Fitness items suitable for the public include swimming, jogging, cycling, mountain climbing, etc. However, vigorous exercise is not necessary to exercise vital capacity. In a quiet state, there are also some exercises that can effectively exercise vital capacity, such as Taijiquan, breathing exercises, and even the methods of regulating breathing such as blowing balloons and candles, which can also help improve vital capacity.
