In this study the authors write: “The greater improvement in physical function with blood flow restriction demonstrates how this addition can increase the quality of simple walking exercise for populations that may be contraindicated to heavy-load resistance training.

• Blood flow restriction walking provides a low-load alternative    to resistance training for improving the physical function of older adults who may be contraindicated to high-load resistance training.
• Blood flow restriction walking improves physical function beyond that of traditional walking exercise.
  
• While higher than traditional walking, ratings of perceived exertion for 10 min of blood flow restriction walking were relatively low and improved with training programme duration.”
