What are the effects of low intensity resistance training with vascular restriction on leg muscle strength in older men?

Research indicates that aging muscle mass declines by 3-8% every decade after age 30, a primary contributor to decreased leg strength in older men. A revolutionary technique, low intensity resistance training with vascular restriction (BFR), has emerged as a promising method to combat this decline by producing significant gains in leg muscle strength and mass, without the high mechanical stress of traditional heavy lifting.
