The coordination of the hands in the elderly requires more neural activity

In the process of aging, people's coordination ability is also decreasing

The research titled "Alpha and beta neural oscillations differentially reflect age-related differences in bilateral coordination" was published in the journal Neurobiology of Aging

Bilateral coordination refers to the ability of people to coordinate the left and right sides of the body during exercise, which is one of the basic skills in daily life

There are two types of coordination: in-phase and anti-phase

Previous studies have found that aging is related to the decline of bilateral coordination, especially the anti-phase coordination

To test this hypothesis, the researchers conducted an experiment using electroencephalogram (EEG)

The subject sits at a transparent table on which eight possible arm movements are shown

The researchers found that compared with the younger group, older subjects had lower synchronization of different parts of the body when they completed anti-phase exercises

The decrease in synchronicity is related to the difference in brain activity during anti-phase exercises

Some people believe that the power of alpha waves is related to the degree of active participation in solving specific tasks

Comparable differences were also observed between the beta wave power of the two age groups

Vadim Nikulin of the Max Planck Institute for Human Cognition and Brain Science said: "Nerve changes occur in the early stages of various pathologies in the brain
