Studies put the squeeze on athletic compression garments

Compression garments are popular with some athletes, such as runners and basketball players, who think the tight-fitting clothing lends a competitive edge. But that may not be the case, according to two new studies presented Thursday at the annual meeting of the American College of Sports Medicine being held in Baltimore.

One study looked at the effect on oxygen consumption among 16 trained male distance runners who wore lower leg compression sleeves. The sleeves, socks that run from just above the ankle to just below the knee, were worn by the runners during a 12-minute running test. The athletes also did the test without the sleeves.

Oxygen consumption did not change significantly in either test. However, small variations were noted--four runners had greater than 1% average increase in oxygen consumption, which means they ran less efficiently. Four runners also had a greater than 1% average decrease in oxygen consumption. There was no change in running mechanics.

Abigail Laymon, the study's lead author and a researcher in the department of kinesiology at Indiana University, also gave the athletes a questionnaire asking their feelings about the compression sleeves. Those who had better outcomes with were more likely to have a favorable attitude about the garments and thought their racing would improve while wearing them.

"Overall, with these compressive sleeves and the level of compression that they exert, they don't seem to really do much," Laymon said in a news release. "However, there may be a psychological component to compression’s effects. Maybe if you have this positive feeling about it and you like them then it may work for you. It is a very individual response."

The other study focused on upper thigh compression garments. Researcher and lead author Nathan Eckert, a human performance doctoral student in the department of kinesiology at Indiana University, tested three types of compression garments on 25 men who did vertical jumps. Each test subject did the jumps while wearing a waist-to-knee garment that fit exactly, one that was a size smaller, and one that was a size larger.

No differences were noted in jump height. "We looked at various different angles to see if the variability changed and nothing significant happened," Eckert said in a news release. "This basically states that at all three different levels of compression did absolutely nothing for them."

Excellent post and well-received here. However, when is the study coming out on spanx? LOL I find the compression garments too constricting, anyway, and welcomed this news.

This study is without merit. Very surprised that Indiana University would produce such a shoddy study with out an scientific basis. They only used on brand of leg sleeves, and they tested them for 12 minutes. Endurance runners run longer than 12 minutes.

A number of Universities around the world have done well documented studies on the benefits of compression clothing. Furthermore the researchers contradict themselves by saying 4 athletes had a 1% increase and 4 athletes had a 1% decrease. At the worst the results are inconclusive.

The lead reasearcher Abigail Laymon has no experience with compression clothing and she is community college student not a University of Indiana professor. Robert F. Chapman also does not have experience with compression clothing nor vascular or circulation expertise. From reading the report it sounds like thye doctored the results in their favor.

Very disappointing.

They should have read the Penn State study on effects of compression LYCRA on athletes.

Other studies have found that compression garments are beneficial primarily during extended exertion (such as marathons or perhaps half-marathons) and to aid post-exertional recovery. Most anecdotal reports are the same, including my personal experience. Once again, the headline goes far beyond the actual findings of these two studies, that examined only sprints.

Well, placebos do work.
