Pneumatic Compression vs Blood Flow Restriction for Muscle Recovery

Purpose

Both BFR and intermittent pneumatic compression are purported to decrease symptoms associated with exercise induced muscle damage (EIMD) that cause delayed onset muscle soreness (DOMS). Blood flow restriction relies on applying pressurized cuffs to the most proximal portion of the limb. Another form of recovery often relied upon is pneumatic compression. The mechanism by which pneumatic compression works is similar to that of a massage, whereby the device progressively increases the pressure on a portion of the limb before releasing and moving further up the limb.The purpose of this study is determine whether BFR or pneumatic compression can be used to decreased DOMS which may indicate enhanced recovery.

Control
The participants will be asked to refrain from exercise 24 hours prior to and following the exercise. Participants will complete all pre-exercise tests (DOMS, CMJ, MVIC). The exercise consists of running on a treadmill situated at a -10% grade at 9 km/hr (5.59 mph) for 20 minutes. This is proceeded and followed by 5 minute warm-up/cool-down periods. Those that are allocated to the "control" group, will not receive treatment after the downhill running protocol.
Experimental
Pneumatic compression
The participants will be asked to refrain from exercise 24 hours prior to and following the exercise. Participants will complete all pre-exercise tests (DOMS, CMJ, MVIC). The exercise consists of running on a treadmill situated at a -10% grade at 9 km/hr (5.59 mph) for 20 minutes. This is proceeded and followed by 5 minute warm-up/cool-down periods. Those allocated to the "pneumatic compression" group will receive 20 minutes of pneumatic compression at 100 mmHg.
  • Device: Pneumatic Compression
    Following downhill running protocol, participants will complete 20 minutes of pneumatic compression at 100 mmHg.
Experimental
Blood flow restriction
The participants will be asked to refrain from exercise 24 hours prior to and following the exercise. Participants will complete all pre-exercise tests (DOMS, CMJ, MVIC). The exercise consists of running on a treadmill situated at a -10% grade at 9 km/hr (5.59 mph) for 20 minutes. This is proceeded and followed by 5 minute warm-up/cool-down periods. Those allocated to the "BFR" group will receive 4 rounds of treatment: 3 minutes will be spent at 100% of resting limb occlusion pressure, followed by 2 minutes of 0% occlusion.
  • Device: Blood Flow Restriction
    Following the downhill running protocol, participants will complete 4 rounds of treatment: 3 minutes at 100% resting limb occlusion pressure, 2 minutes of 0% resting limb occlusion pressure.
