Effect of Skinny Jeans on Muscle Activities of the Quadriceps Group and Gluteus Maximus Muscles During Ascending Stairs
Skinny Jeans is a tight pants made by denim or spandex, and snugly fits around the calf and ankle. The purpose of this study was to evaluate the effect of the skinny jeans on muscle activities of vastus medialis, vastus lateralis and gluteus maximus during ascending steps. Twenty health young females spontaneously participated in this study. All participants conducted skinny jeans or training pants and were measured the muscle activation by surface electromyography (EMG) during stair up. The muscle activation was recorded from three muscles including vastus lateralis (VL), vastus medialis (VM), and gluteus maximus (GM). The corrected data of muscle activities was normalized to the value of maximal voluntary isometric contraction (%MVIC). The normalized EMG levels (%MVIC) of the VL, VM and GM were compared using a paired t-test. According to the results of this study, the ascending steps worn the skinny jeans was significantly increase the muscle activation of vastus medialis and gluteus maximus compared to training pants. However, the vastus lateralis was significantly less activation in wearing skinny jean than training pants. In addition, there was significant difference EMG activity of VM/VL ratio (p<.001). These results suggest that the ascending step conducted the skinny jean would be more activation of the muscles on surrounding the hip and knee joints and imbalance between the two muscles (vastus lateralis, vastus medialis). The results also suggest that the more muscle activation and imbalance between vastus lateralis and vastus medialis of skinny jean are, the more muscle fatigue induce.
