No influence of ischemic preconditioning on running economy.

Purpose: Many of the potential performance-enhancing properties of ischemic preconditioning suggest that the oxygen cost for a given endurance exercise workload will be reduced, thereby improving the economy of locomotion. The aim of this study was to identify whether ischemic preconditioning improves exercise economy in recreational runners.

Methods: A randomized sham-controlled crossover study was employed in which 18 adults (age 27 ± 7 years; BMI 24.
