Abstract
The aim of this study was to evaluate changes in electromyographic activity with the use
of gradual compression stockings (GCSs) on middle‐distance endurance athletes’ performance,
based on surface electromyography measurement techniques. Sixteen well‐trained athletes were
recruited (mean ± SD: age 33.4 ± 6.3 years, VO2max 63.7 ± 6.3 mL∙kg−1∙min−1, maximal aerobic speed
19.7 ± 1.5 km∙h). The athletes were divided into two groups and were assigned in a randomized
order to their respective groups according to their experience with the use of GCSs. Initially, a
maximum oxygen consumption (VO2max) test was performed to standardize the athletes’ running
speeds for subsequent tests. Afterward, electromyographic activity, metabolic, and performance
variables for each group were measured with surface electromyography. In addition, blood lactate
concentration was measured, both with and without GCSs, during 10 min at 3% above VT2 (second
ventilatory threshold), all of which were performed on the track. Next, surface electromyography
activity was measured during a 1 km run at maximum speed. No significant changes were found in
electromyography activity, metabolic and performance variables with GCSs use (p > 0.164) in any
of the variables measured. Overall, there were no performance benefits when using compression
garments against a control condition.
