简要总结
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.

研究组 & 干预措施
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.
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.
干预措施: Pneumatic Compression (Device)
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.
干预措施: Blood Flow Restriction (Device)
结局指标
主要结局
Counter Movement Jump Height
时间窗: Immediately before and immediately after exercise, immediately after treatment, 24-hours post treatment.
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.
Maximal Voluntary Isometric Contraction
时间窗: Immediately before and immediately after exercise, immediately after treatment, 24-hours post treatment.
Participants will be asked to complete an MVIC to assess muscle function.
Sedentary delayed onset muscle soreness
时间窗: Immediately before and immediately after exercise, immediately after treatment, 24-hours post treatment.
Using a visual analog scale, participants will be asked to rate their level of soreness while at rest.
Active delayed onset muscle soreness
时间窗: Using a visual analog scale, participants will be asked to rate their level of soreness while at rest.
Using a visual analog scale, participants will be asked to rate their level of soreness while completing a wall sit.
