Neuroplasticity
Findings provide insight into the complex interplay between grip strength, mental health, and brain structure.
Grip strength is associated with increased grey matter volume in the temporal cortices and subcortical regions of the brain. In sum, the current study below shows that stronger grip strength was associated with better mental health, cross-sectionally and longitudinally. At the brain level, research found widespread associations between grip strength and greater grey matter volume in subcortical and temporal cortices. Moreover, GMV also correlated with better mental health and considerably mediated the effect of grip strength on cognitive functioning. Overall, findings provide insight into the complex interplay between grip strength, mental health, and brain structure.
Perhaps the most unambiguous evidence is when training increases the thickness or volume of neural structure. It has been demonstrated that sedentary older adults who engage in aerobic exercise can delay shrinkage in prefrontal cortex, an area maximally sensitive to age-related volumetric shrinkage. Repetitive tractioning of our spines in our yoga practice forms neural pathways, building "cognitive reserve" buffering against age-related cognitive decline.
Tuning the biorhythm of our breath and heart cycles. Our yoga practice restores the clockwork-like nature of our nervous and endocrine system, bringing balance where there was stress. Integrating parts of our brain for symmetric patterns for mind body harmony.
Research has shown that even in older adults, the brain retains a significant capacity for neuroplasticity, meaning new neural connections can still form and existing ones can be strengthened through stimulating activities. Sexy body sure! Sexy brain, yes please!
