The purpose of this study was to compare the kinetics, kinematics, and muscle activation patterns of the countermovement jump, the power clean, and the jump squat with the expectation of gaining a better understanding of the mechanism of transfer from the power clean to the vertical jump. Ground reaction forces, electromyography, and joint angle data were collected from 20 trained participants ...

PURPOSE One of the aims of the treatment in ambulant cerebral palsy (CP) patients is improvement of gait. The level of gait pathology is assessed by instrumented gait analysis, including surface electromyography. The aim of this study was to investigate the relation of the abnormality level of the gait and the co-contraction of the agonist-antagonist muscles, and relation between symmetry left ...

The purpose of the present study was to define the degree of muscular activation while walking in water in order to aid rehabilitation therapists in their choice of exercises for daily clinical practice in aquatherapy. This study compares the electromyographic (EMG) activity of the rectus femoris, the soleus of the right lower limb and the contra-lateral lumbar erector spinae, during gait in wa...

The effect of in-bag dry- and wet-ageing on metabolite profiles lamb legs was determined using Rapid Evaporative Ionisation Mass Spectrometry (REIMS). Using orthogonal projection to latent structures-discriminant analysis (OPLS-DA) with REIMS, 1705 ions were identified (Q2 = 0.86) in four muscles: m. semimembranosus, biceps femoris, vastus lateralis rectus femoris. A total 663 metabolites diffe...

OBJECTIVES To investigate the validity and reliability of surface electromyography (EMG) as a new non-invasive determinant of the metabolic response to incremental exercise in elite cyclists. The relation between EMG activity and other more conventional methods for analysing the aerobic-anaerobic transition such as blood lactate measurements (lactate threshold (LT) and onset of blood lactate ac...

INTRODUCTION Critically ill patients are characterized by increased loss of muscle mass, partially attributed to sepsis and multiple organ failure, as well as immobilization. Recent studies have shown that electrical muscle stimulation (EMS) may be an alternative to active exercise in chronic obstructive pulmonary disease (COPD) and chronic heart failure (CHF) patients with myopathy. The aim of...

OBJECTIVE To study increases in electromyographic (EMG) response from the right and left rectus femoris muscles of individuals with long-term cervical spinal cord injuries after EMG biofeedback treatment. DESIGN Repeated measure trials compared EMG responses before and after biofeedback treatment in patients with spinal cord injuries. MAIN OUTCOME MEASURES The Neuroeducator was used to anal...
