    So far, clinical trials have failed to prove
    the benefits of aerobic exercise using diffusion magnetic resonance imaging on adult white matter

    White matter is generally considered to be a passive brain tissue.
    It is in the back seat of its active gray matter counterpart, where powerful neurons live

    .
    If neurons are brain cells that produce signals and electrical impulses, then the axons in the white matter are the lines that transmit these signals between neurons

    White matter is mainly composed of the axon wiring of the brain; due to the fatty proteins and lipids covering the axon fibers, it has the "white" homonym
    .
    The insulation provided by these proteins and lipids helps to increase the speed at which signals are transmitted from one brain area to another

    In this study , the researcher collected a sample of 180 healthy but considered inactive elderly people .
    Then, the participants were randomly divided into small groups and met three times a week for six months

    In this study , the researcher collected a sample of 180 healthy but considered inactive elderly people .
    Then, the participants were randomly divided into small groups and met three times a week for six months
    .

    The first group : walk about 40 minutes per lesson ; the second group : participated in a dance class that gradually became more difficult within six months ; the third group : as a control for the study, it was limited to balance and stretching exercises for the purpose of Keep your heart rate low
    .
    Each participant underwent a series of magnetic resonance imaging and cognitive and cardiopulmonary tests before and after the intervention to assess the impact of physical activity on the brain

    To measure changes in white matter over time, the team used a technique called the T1w/T2w ratio, which involves MRI scans of the participants’ brains
    .
    When performing an MRI scan, researchers and doctors usually look at T1-weighted and T2-weighted images

    .
    These are the black, white, and gray images of the brain that often appear in medical dramas when the character's brain is injured

    .
    In the T1-weighted image, the white matter of the brain is white and the
    gray matter is gray, but on the T2-weighted image, the colors are inverted
    .
    It is this color that can help researchers identify changes in brain anatomy, such as tumors, atrophy, or in this case, changes in white matter

    Since T1-w and T2-w images are widely used in most studies, the team decided to combine these images to create a ratio to enhance the contrast associated with the white matter of the brain
    .
    Using algorithms and advanced statistics, the team was able to extract values ​​showing how specific areas of white matter changed during the six-month intervention

    The results of the study found that participants in the walking group and dance group had increased white matter after six months of aerobic exercise
    .
    In other words, physical activity has a positive effect on the white matter of the brain, especially in the areas most prone to aging, such as the corpus callosum and cingulate.
    They give important cognitive abilities such as memory and executive functions

    In addition, the walking group experienced the additional benefits of improved episodic memory after the intervention and was able to recall their lifetime memories better
    .
    Therefore, activities that truly increase heart rate may be more suitable for combating certain side effects of brain aging

    However, for less strenuous activities, the situation was the opposite: participants in the research team were limited to low-intensity exercises, such as stretching or balancing postures, and experienced a normal, slow white matter signal decline within six months, and there was no change in episodic memory

    In short, the results of
    this study show that the white matter areas that are prone to aging retain a certain degree of plasticity, which can be induced by aerobic exercise training .
    In addition, the
    researchers provided evidence that the T1w/T2w signal may be a useful and widely used measurement method for studying short-term plasticity and degradation in adults
