An Electromyographic And Video Motion Analysis Study Of The Drawback And Hold Phases Of Compound Bow Versus A Traditional Bow In Experienced Archers, Jason Brodina

Physical Therapy Scholarly Projects

Background/Purpose: Archery is quickly becoming an increasingly popular sport, with limited research in the training and rehabilitation of archers. The purpose of this study is to identify the major muscles and timing of recruitment during the drawback and hold of a bow, and to determine the presence of differences in this recruitment between a compound and traditional bow.

Subjects/Methods: Seven males between the ages of 36 to 51 years of age completed 6 drawbacks each with a compound bow and a traditional bow. Surface electrodes on the subjects and reflective markers on the bow were used to analyze electromyographic activity …

An Electromyographic Study Of Lower Trapezius Muscle Activity During Exercise In Traditional And Modified Positions, Rebecca Lee. Johnson

Physical Therapy Scholarly Projects

Shoulder rehabilitation commonly overlooks the influence of scapular muscles in providing the stability necessary for the shoulder to function properly. When considering muscles acting on the scapulothoracic articulation, literature suggests that the lower trapezius is a key stabilizer of this articulation. Traditionally, the lower trapezius is exercised while the patient is in a prone position with the humerus abducted 1450 while performing forward elevation. Unfortunately, repeated overhead activity has been proven to increase the incidence of shoulder impingement. In an effort to avoid exercising the lower trapezius in a position that would compromise the shoulder complex, a modified position of …

An Electromyographic And Video Motion Analysis Study Of Sprinters At Varying Speeds And Inclines, Christine Ann Rygh

Physical Therapy Scholarly Projects

Athletes desire to succeed in their respective sport. Several training programs claim to enhance athletic performance by loading specific muscles and joints needed for increased speed, power, and strength in a sport specific manner. One such training regimen is the Frappier Acceleration® program, in which the core element involves sprinting on a treadmill at varying speeds and inclines. The purpose of this study is to describe muscle activity and joint motion while running on a treadmill at different speeds and inclines.

Eleven males between the ages of eighteen and twenty-two years of age ran on a treadmill at five different …

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). …
