This study showed evidence that foam rolling induced modulation of spinal nervous system excitability (in other words, change in the sensitivity of the muscle spindle reflex).
Running in Highly Cushioned Shoes Does Not Decrease Injuries
The researchers attribute the greater impact loading with the highly cushioned shoes to a stiffer leg during landing than with conventional shoes.
Previous Leg Injury Increases Risk of Other Leg Injuries
Once one joint/structure/tissue is injured, compensation patterns usually occur in which the individual offloads physical stress to other areas of the body. This would logically lead to an increased risk of use/overuse/misuse/abuse to these other areas, likely eventually leading to injury.
