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.

Following downhill running protocol, participants will complete 20 minutes of pneumatic compression at 100 mmHg.
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.

RECRUITINGCounter Movement Jump Height
Participants will be asked to complete three consecutive counter movement jumps with hands on hips. The CMJ will be used as an indirect measure of muscle function.
Time frame: Immediately before and immediately after exercise, immediately after treatment, 24-hours post treatment.
Maximal Voluntary Isometric Contraction
Participants will be asked to complete an MVIC to assess muscle function.
Time frame: Immediately before and immediately after exercise, immediately after treatment, 24-hours post treatment.
Sedentary delayed onset muscle soreness
Using a visual analog scale, participants will be asked to rate their level of soreness while at rest.
Time frame: Immediately before and immediately after exercise, immediately after treatment, 24-hours post treatment.
Active delayed onset muscle soreness
Using a visual analog scale, participants will be asked to rate their level of soreness while completing a wall sit.
Time frame: Using a visual analog scale, participants will be asked to rate their level of soreness while at rest.
