![]() ![]() In theory, PCDs promote faster blood flow, nutrient delivery, and waste removal from the compressed muscles. Thus, the rate of DOMS recovery from multiple treatments is unknown.Ī few studies have been conducted that investigate the use of a PCD in the recovery from strenuous exercise. Further, most previous research investigating PCDs have used a single treatment. ![]() However, little is known regarding the use of these devices in the recovery from DOMS, particularly in comparison to compression garments. Pneumatic compression devices, which offer short-term but more intense dynamic compression, have been used in the treatment of diseases such as lymphedema ( 3). The sequential nature of inflating, holding, and deflating cuffs returns blood, and thereby wastes and metabolites, from the periphery to the core. Dynamic PCDs, such as the device used in this study, have up to five separate compartments which inflate sequentially from the most distal part of the limb towards the center of the body. Pneumatic compression devices (PCDs) provide compression to the limbs via inflatable cuffs. While the use of compression garments during recovery has shown to be beneficial, other forms of compression, such as pneumatic compression, have received little attention when directly compared to these garments. It is thought that compressive garments aid in prevention of excessive muscle swelling and enhance blood flow and the removal of waste products and muscle metabolites, which result in greater range of motion (ROM) about the affected joint, less severe decrements in muscular strength and power, and reduced pain ( 4). However, recovery from strenuous exercise resulting in delayed-onset muscle soreness (DOMS) has significantly improved when wearing such garments. Previous research has demonstrated little to no benefit to while wearing compression garments while exercising ( 10). These findings suggest that daily treatments using a PCD further reduce peak disturbance and recovery time from DOMS of the elbow flexors when compared to a continuously-worn CS.Ĭompression garments have received attention due to their purported abilities to improve exercise performance and speed muscle recovery and are available from a multitude of manufacturers for almost any sport imaginable. ![]() ROM disturbances during the PCD treatment were lower (mean peak reduction in ROM −9.04 degrees in PCD compared to −17.25 degrees in CS, p < 0.05) and peak pain was lower by 39% (27.5 mm in PCD compared to 45.2 mm in CS, p < 0.05) when compared to the CS treatment. 2.0 cm in CS, p = 0.012), however there was no difference in lower arm circumference ( p = 0.091). Muscle swelling, assessed via changes in upper arm circumference, was significantly lower in the PCD treatment (1.7 vs. Treatment order was randomized and balanced. Subjects rested for seven additional days before completing another muscle-damage protocol and the remaining treatment. Swelling, range of motion (ROM), and pain were measured daily during the five-day recovery period. Immediately following the muscle-damage protocol, subjects either wore a CS continually for five days or completed daily, 20-minute PCD treatments for five days. The muscle-damage protocol consisted of four sets of 25 repetitions of isokinetic concentric elbow flexion followed by eccentric elbow extension at 60°/second. Eight college-aged students participated in this crossover design study. The purpose of this study was to determine the effects of a pneumatic compression device (PCD) compared to a continuously-worn compression sleeve (CS) during a five-day recovery period from delayed-onset muscle soreness (DOMS) of the elbow flexors. ![]()
