BACKGROUND Minimising the likelihood of injury to the anterior cruciate ligament (ACL) during abrupt deceleration requires proper synchrony of the quadriceps and hamstring muscles. However, it is not known whether simple verbal instructions can alter landing muscle activity to protect the knee. OBJECTIVE To assess the efficacy of verbal instructions to alter landing muscle activity. METHODS...
The aim of this study was to compare the effects of two pedaling methods on lower limb muscles fatigue index and muscular activity in road cyclists. For this purpose eight road cyclists participated in two separately session in laboratory. They were pedaling with pushing technique in first session and circling (pullingpushing) technique in the other session. Surface electromyography activity...
Background: Muscle fatigue can change the muscle activation pattern during running and causes some disorders in running biomechanics. The aim of present study was to determine the effect of muscle fatigue on electromyographic activation pattern and co-contractions of lower extremity muscles during running. Methods: Fourteen males (age: 23.76±2.14 years, weight: 78.45±2.54 kg, hei...
Background Researchers are increasingly using echo-intensity (EI) as an index of muscle quality or fatty and fibrous tissue infiltration. EI is moderately associated with strength and/or power a better predictor performance than measures mass. In this regard, ultrasound-derived may be promising skeletal assessment tool for monitoring the progression physical performance. However, there has been...
INTRODUCTION Bilateral rectus femoris haematoma following a simultaneous strain of the quadriceps muscles is a very rare condition. CASE PRESENTATION We report the case of a 21-year-old Greek Caucasian female rowing athlete who was injured on both thighs. She complained of pain and inability to walk. Physical examination revealed tenderness over the thighs and restriction of knee movement. Th...
