Comparison In Muscle Activity Between The Back Squat, Romanian Deadlift And Barbell Hip Thrust During Hip Extension, Jose Delgado
Comparison In Muscle Activity Between The Back Squat, Romanian Deadlift And Barbell Hip Thrust During Hip Extension, Jose Delgado
Theses: Doctorates and Masters
Common resistance-training exercises such as back squat, Romanian deadlift (RDL), and hip thrust have been used by strength and conditioning specialists to target the musculature used during hip extension. Little is known about the differences in muscular activity of the hip extensors between these exercises, so it is not known which is the most effective as a hip extensor exercise. The primary purpose of this study was to compare muscle activity of several muscles during the high-bar back squat, RDL and barbell hip thrust, using men with a minimum of 1 year of lower-body resistance-training experience. Surface electromyography (EMG) was …
An Electromyographic Comparison Of Neck Conditioning Exercises, Jemma L. Coleman
An Electromyographic Comparison Of Neck Conditioning Exercises, Jemma L. Coleman
Theses : Honours
It is known that sustained muscular contractions can cause muscular pain, which explains the prevalence of neck pain of employees in static and semi-static work such as dentistry, sewing machine and computer operation. Additionally, exposure to high and sustained gravitational forces in high performance combat pilots is another source of neck pain in the workplace. Individuals with neck pain have been found to show decreased neck strength, in particular neck flexor strength has been found to be less than that of the general population. It has been suggested that neck-conditioning exercises may be useful in the prevention and rehabilitation of …
Force And Electromyographic Responses To Ergometer Rowing, Darryl A. Turner
Force And Electromyographic Responses To Ergometer Rowing, Darryl A. Turner
Theses: Doctorates and Masters
During many athletic events, fatigue influences the physiological and biomechanical characteristics of performance. For optimal performance in events such as rowing, athletes must maintain a skilfully co-ordinated movement technique. The ability to produce high force outputs during repetitive contractions is influenced by fatigue and dependent on a number of factors including neuromuscular activities. Neuromuscular activation may be expressed by amplitude and frequency characteristics of the electromyographic signal (EMG) sample from the muscle. During sustained isometric contractions, changes in EMG characteristics are related to changes in force, which may be useful in monitoring the fatigue process (Basmajian, 1974: De Luca, 1985). …
