THE EFFECT OF COMPRESSION CLOTHING ON MUSCULAR STRENGTH AND ENDURANCE
Notice bibliographique
Résumé
Purpose: Claims have been made in the popular press as to the efficacy of compression clothing to improve endurance and jumping performance. The press has reported a 30% enhancement of endurance and power. Dupont, Brooks, Spalding, and other companies have incorporated the compression concept into athletic clothing according to magazine reports. The purpose of the proposed study was to determine the efficacy of compression athletic clothing to enhance muscular strength and endurance in target muscle groups. METHOD: The study was a repeated measure cross over design. Four compression garments (Bioconcepts, Phoenix, Arizona) were custom fabricated for each athlete. Two were “t-shirts” that extended to the elbow bilaterally and two garments were “shorts” that extended to the knees. The garments were designed to provide 40mm Hg compression unilaterally, and the second garment provided compression to the opposite side. Varsity, provincial and national level athletes (n = 15) from a variety of sports were recruited to perform repeated isokinetic testing (Biodex 3, Shirley, New York) of elbow flexion/extension and knee flexion extension at 120 degrees/second wearing each of the garments. Statistically, eight within-subject comparisons were made. We evaluated whether there were statistically significant differences between compressed and non-compressed conditions for each direction (flexion/extension), on each limb. For example, we tested whether there was a statistically significant difference between right elbow flexion when compressed compared to non-compressed. Summary of Results: There were no statistically significant differences in performance using compression garments for 7 of 8 tests (p-values ranged from 0.2 to 0.9). Left elbow extension demonstrated a statistically significant decrement in performance with compression (p = 0.03). Discussion: A randomized repeated measure design provides a strong scientific method to investigate the effect of compression athletic garments. We would expect, given the magazine reports, to find consistent improvements in muscular performance. However, none of the cross over tests provided support for any consistent benefit from the use of compression garments. Therefore, the use of compression garments remains a personal preference rather than a demonstrable advantage. The current study has limitations. Most important is the variability in the perceived compression. Some subjects only noticed a small difference between sides, whereas others felt compression to an uncomfortable level. We did not measure the actual level of compression. More subjects are needed to determine if the results of the current study are consistent and reproducible.

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
