Purpose The purpose of this study was to assess the effects of practicing Baduanjin exercises on the lower extremities of subjects using electromyography analysis. Subjects 110 healthy adults were randomly assigned as subjects to two groups: SG group who received sixteen weeks of Baduanjin training and CG group who received no training. Methods The methods used in this study included the us...

Anatomical studies describe the vastus medialis (VM) as being subdivided into two morphologically distinct components, obliquus (VMO) and longus (VML). However, there are discrepancies regarding functional differentiation of these components. The aim this study was to compare levels activation VMO VML by high density surface electromyography. Twelve healthy young women (age: 21.4 ± 2.0 years; ...

(1) Background: this study aimed to determine if there are differences in quadriceps and hamstring muscle activation professional male female soccer players. (2) Methods: was recorded by surface electromyography 27 players (19 8 female). The performed the Bulgarian squat lunge exercises. Vastus medialis, vastus lateralis, rectus femoris, semitendinosus, biceps femoris were muscles analyzed. (3)...

[Purpose] We investigated the difference in onset time between the vastus medialis and lateralis according to knee alignment during stair ascent and descent to examine the effects of knee alignment on the quadriceps during stair stepping. [Subjects] Fifty-two adults (20 with genu varum, 12 with genu valgum, and 20 controls) were enrolled. Subjects with > 4 cm between the medial epicondyles of t...

BACKGROUND The aim of this study was to investigate whether electromyographic manifestations of fatigue and exercise tolerance were related to stage of disease in men with a COPD diagnosis. METHODS Fourteen men with COPD with a diagnosis of mild to severe air flow obstruction were involved in 2 separate testing sessions. The first one consisted of a pulmonary function (FEV1 and FEV1/FVC) and ...

Purpose: A variation in squatting technique is using arms to actively push the bar up with the upper limbs which is common in bodybuilding. This study aimed to compare the Electromyography (EMG) activity of selected muscles during squat with and without upper limb assistance. Methods: This was a quasi-experimental study. Fifteen healthy male power lifters (using the convenience sampling method...

Patellofemoral pain is a common ailment within both the running and general populations. Many of the structures of the anterior knee that comprise the patellofemoral joint can be the source of chronic pain and inflammation that is associated with this condition. Much of the evidence in the literature points to a delay in activation of the vastus medialis oblique muscle as compared to the vastus...
