The human hand is extraordinary.
Not only does it allow us to shoot, catch or catch something, it is also an indicator of health.
By evaluating the amount of power a person can generate with their footprint, researchers can understand a person’s strength, understand their rate of aging, and even diagnose certain health conditions such as heart disease and cancer.
Gripping strength can be measured by means of a dynamometer in which the person grasps the device in the same way as holding a glass, with the elbow turned sideways and at a right angle.
The device is then held down for about five seconds. The test is usually done with both hands, with three handles on each hand, and then the average strength is measured.
Men in their 20s and 30s have the greatest power, while women over 75 have the least power.
The average footprint of people between the ages of 20-29 is 46 kilos for men and 29 kilos for women. When the person reaches the age of 60 to 69, this measure decreases to 39 kilograms and 23.5 kilograms, respectively.
What does it mean to have less power in your hands?
Some studies have shown that having a lower than average grip strength compared to people of the same sex and age group is associated with an increased risk of cardiovascular failure. A low strength indicates detrimental changes in the structure and functions of the heart.
Likewise, a poor grip can predict heart death, death from any cause, and hospitalizations for heart failure.
The strength of the handshake can also be useful in predicting cancer survival. Although survival is based on other factors such as cancer type and time of diagnosis, one study found that the stronger the footprints of patients, the more likely they were to beat lung cancer.
Diagnosis of colorectal, prostate or lung cancer in men and breast or lung cancer in women is associated with a five kilogram reduction in hand strength in people aged 60 to 69 years.
This deterioration was also associated with an increased chance of dying from colorectal cancer in men and breast cancer in women.
Obesity is also associated with a weaker footprint later in life. The presence of fat around a muscle reduces the muscle’s effectiveness.
A recent study showed that people who developed type 2 diabetes had a weaker handshake. This is likely due to the presence of fat in the muscles, which makes them less efficient and consequently causes muscle inactivity and breakdown.
The strength of the hand decreases with age. Over the years, as the body loses muscle mass, it also loses its strength in the hands.
Aging causes a reduction in muscle mass (and function) of 1% per year from middle age. This can result in a loss of up to 50% of muscle mass between the ages of 80 and 90.
However, aging progresses at different rates in humans.
This means that grip strength may decrease due to age-related changes in the nervous system, when signals do not move as quickly, or because of a loss of muscle mass in the arms.
Another study showed that decreased grip strength in the elderly was associated with lower cognitive function.
Muscle loss occurs in the body as certain health conditions and age develop.
But measuring strength in many areas can be difficult, so hands are essential. Their ability to produce refined and powerful moves makes them an indicator of overall health.
When we get sick, including diabetes, heart, or cancer, the ability of our muscles to produce strength decreases. Its functionality and mobility also deteriorates.
This is due to a combination of factors such as decreased cardiac function, muscle mass and muscle mass, and fatigue by allowing prolonged movements.
Certain health conditions can also cause fatigue, making us less likely to move and exercise, thus creating increased muscle loss and decreased strength cycling.
In particular, cancer can limit the functioning of our digestive system, making it difficult to eat and reduce our appetite.
The foods we eat, especially proteins, are important for maintaining muscle mass and strength. Without enough food to energize us, the body must use its internal reserves to produce it.
One of the main ways to do this is by burning unused tissue, and muscle is the favorite fuel for this condition. The loss of body mass reduces the body’s natural reserves and potentially its ability to resist chronic long-term illness.
One of the secrets to maintaining health and muscle strength is exercise. Muscles break if not used.
For example, it is known that walking patients after surgery prevents the loss of muscle and bone mass and reduces the duration of hospital stay.
Either way, a strong handshake can provide more information about you than you think.
