Australian researchers have found a link between poor grip strength and hypoxemia – low levels of oxygen in the blood.
Experts assessed the grip strength and oxygen saturation of the blood of middle-aged and older men, while measuring body fat and body mass and tailoring lifestyle information such as diet, smoking and physical activity.
They found a link between lower levels of oxygen saturation in the blood and lower grip strength, whether their muscle mass was high or low.
Experts suggest that a lowered fist could be a telltale sign of hypoxemia, which interferes with heart and brain function by not delivering enough oxygen to organs.
While the study showed a link between these two factors, “causation cannot be proven,” which means that it is not certain that lack of oxygen in the blood results in poor adhesion.
Study author Dr David Stevens, of Flinders University in Adelaide, said: “While looking at grip strength, my study does not show that people are at risk of poor health more. late in life and die prematurely (although many studies show this. “)”.

Instead, my study showed that regardless of male muscle mass, worsening hypoxemia was associated with decreased grip strength.
Decreased grip strength is already linked to an increase in the severity of a group of chronic conditions, including cardiovascular disease and COPD.
In this new study, the researchers originally aimed to determine the association between grip strength, muscle mass and fat mass, and obstructive sleep apnea (OSA), a potentially serious sleep disorder that could itself cause hypoxia.
Researchers evaluated 613 men, aged 40 to 88, for androgens, inflammation, lifestyle, environment and stress (MAILES), a long-term sample followed since 2009 to analyze the risk of heart disease and metabolism in humans.
They used a Smedley analog dynamometer – a small, portable device with a dial – to measure participants’ grip strength.
Experts also used a special type of x-ray called dual x-ray absorptiometry to determine whole body muscle mass and fat mass.
The researchers found that a decrease in grip strength was linked to a decrease in the isotope of oxygen.
Professor Robert Adams of Flinders University says that regardless of muscle mass, a simple grip test can highlight underlying issues associated with aging and worsening hypoxemia.
“Without good levels of oxygen in the blood, we cannot make the most of the muscles that we have,” he said.
Dr Stevens acknowledged that the fact that all participants were men was an “inherent limitation” of the study and meant that the results may not be generalizable to women.
The study is published in the journal Nature and Science of Sleep.
