Penn State Researchers Discover Abdominal Contractions Aid Brain Health
A study conducted by researchers at Penn State University has revealed that simple body movements, such as abdominal contractions, may play a significant role in maintaining brain health. The research, published in Nature Neuroscience, suggests that when abdominal muscles tighten, they exert pressure on blood vessels connected to the spinal cord and brain, causing the brain to shift slightly within the skull. This movement facilitates the flow of cerebrospinal fluid across the brain, potentially aiding in the removal of waste that could interfere with normal brain function. The study utilized advanced imaging techniques, including two-photon microscopy and microcomputed tomography, to observe these effects in mice. The findings indicate that even mild abdominal contractions, such as those occurring when standing up or taking a step, can create this beneficial effect, likened to a hydraulic system where the abdominal contraction acts as a pump.
