Blood Flow Restriction Training to Prevent Cognitive Decline?

This study examined whether blood flow restriction training could possibly be utilized as an effective intervention technique for elderly adults suffering from cognitive decline. 

Here are some quick takeaways from this study:

"Resistance training with BFR is more efficient to increase muscle hypertrophy and strength as compared to the same resistance training without BFR and for a resistance training with BFR, lower exercise loads are needed to achieve comparable muscular adaptions (e.g., increase in muscle mass) as compared to high-load resistance training"

"Short-term and long-term resistance training with BFR improve cognitive performance as well as brain health to a greater extent than resistance training without BFR may provide deeper insights into the interplay between neurobiological mechanisms and cognitive processes. A deeper understanding of underlying exercise-induced and cognition-related neurobiological mechanisms is urgently needed to develop efficient prevention strategies (e.g., decelerate cognitive decline due to aging process) and to optimize rehabilitation strategies for individuals with worsened cognitive functions (e.g., older individuals with dementia). Here, the resistance training with BFR might be a promising strategy of exercise intervention."
