An Electromyographic Study Of Back And Lower Extremity Muscle Activity During A Traditional Squat And The Plyo Press Leg Press, Heidi C. Ivesdal

Physical Therapy Scholarly Projects

Strength training is a primary factor in athletics and rehabilitation. Lower extremity strength training has traditionally consisted of free weights, biomechanically designed weight machines, or plyometrics. The Plyo Press is a new machine that is currently being utilized in the Frappier Acceleration Program for athletes. It is specifically designed for lower extremity strength training in combination with plyometrics. The principle behind its design is to build strength in the most effective way to enhance speed and dynamic activity without the stress to the low back or legs that is present with the use of free weights.

An Emg And Video Analysis Of The Wrist Flexors During A Sidearm Baseball Delivery, Cordell J. Mack Jan 1997

An Emg And Video Analysis Of The Wrist Flexors During A Sidearm Baseball Delivery, Cordell J. Mack

Physical Therapy Scholarly Projects

By understanding proper pitching mechanics, therapists can develop better preventative and rehabilitation programs for pitchers. The purpose of this study was to explain the joint motions and muscle activity that occur at the elbow during both an overhand and sidearm baseball pitching delivery. Three healthy adult pitchers with recreational sidearm pitching experience were examined with synchronized high-speed video digitization and surface electromyography (EMG). It was proposed that the increased valgus moment during the acceleration phase due to the sidearm delivery would subsequently show an increase in EMG activity by the wrist flexor-pronator group to provide additional varus torque in minimizing …

Physical Therapy Faculty Burnout: A Survey, Donna J. Mcleod

Physical Therapy Scholarly Projects

Burnout is a serious concern in today's world, especially in the educational setting. Burnout not only affects the individual physically and emotionally, but it can also affect the work place. More specifically it can lead to increased absenteeism, job turnover, and other work associated withdrawal behaviors. Furthermore, burnout has the potential of affecting many other people above and beyond that individual who is burned out.

At this time, new physical therapy programs continue to be developed across the United States, although there is already a limited number of faculty in the physical therapy field. Therefore, due to the physical therapy …

Athletic Nutrition, Glenn M. Taira Jan 1997

Athletic Nutrition, Glenn M. Taira

Physical Therapy Scholarly Projects

Science has broken down many of the barriers that once kept athletes from performing at their very best. This has been done through the scientific study of athletes and the development of a combination of proper training, technique, mental attitude, and nutrition. While training and technique are variables that come with time and practice, proper nutrition can produce positive changes in an athlete's performance in a relatively short period of time. Eating the right kinds of foods, in the right proportions, for a given type of athletic event (Le. aerobic, anaerobic, strength, and muscular definition) can provide an athlete the …
