Effects of Foot Position during Squatting on the Quadriceps Femoris: An Electromyographic Study

International Journal of Exercise Science 6(2) : 114-125, 2013. Weightlifters have commonly believed that changing joint position can alter specific muscle activation. The magnitude of force produced by a muscle is highly dependent upon the length of the muscle. The purpose of this study was to determine the effect of foot positioning on muscle activation of the superficial quadriceps as measured by surface electromyography (sEMG) during a functional squatting movement in healthy adults. Twenty physically active asymptomatic adults (7 females and 13 males) were included in the study while four different foot positions (Neutral, Internally Rotated, Externally Rotated, and Staggered) were assessed. Three quadriceps muscles (Rectus Femoris (RF), Vastus Medialis Oblique (VMO), and Vastus Lateralis Oblique(VLO) were measured. Raw EMG was transformed using a root mean square algorithm. Six one-way repeated measure ANOVAs were conducted to examine the peak and average RMS amplitude for each muscle across each condition, with an alpha level of 0.05 set a priori. Across all foot positions only the Staggered foot position reached statistical significance when compared to all other foot positions for each muscle group. Results suggest that altering the foot position during a partial weight squat has little to no effect on the EMG amplitudes of the quadriceps. However, more research is needed to examine the concentric and eccentric phases of the squatting motion separately with the addition of full weight bearing squats

Moving from Computed Radiography to Digital Radiography, a Collaborative Approach to Improve Image Quality

The University of New Mexico School of Medicine (UNM SOM) and the University of New Mexico Hospital (UNMH) have long worked together to deliver high quality patient care to the citizens of New Mexico and the surrounding region. One of the key ways that the Department of Radiology has worked to deliver the highest quality care to the patients of UNMH is by establishing a Quality Assurance Committee. The committee is composed of radiologists, technologists, medical physicists and support staff who all lend their expertise to review and help solve any quality assurance issues for the department. This poster is one example of how a team\u27 within the Quality Assurance Committee helped solve an important image quality issue within our department, and improved patient care. This project is an example of how to form a team (triad) comprised of radiologists, technologists, and physicists to utilize post-processing techniques in digital radiography (DR) in order to optimize image acquisition and improve image quality.\u2

Chemical Reactions: Marijuana, Opioids, and Our Families

Chemical Reactions: Marijuana, Opioids, and Our Families is the seventh Massachusetts Family Impact Seminar. This seminar was designed to emphasize a family perspective in policymaking on issues related to the legalization of marijuana and managing the opioid abuse crisis in the Commonwealth. In general, Family Impact Seminars analyze the consequences an issue, policy, or program may have for families

Editorial: Coastal risk: shores and deltas in peril

Coastal systems are the result of a natural equilibrium between hydrodynamic, atmospheric, and terrestrial parameters and sediment dynamics. In the Anthropocene, this equilibrium in many coastal regions can be altered by human activities. These activities may globally magnify the effects of extreme meteorological events and sea level rise and directly influence coastal processes down to a local scale within and between river catchments, the sea, and the coast. While most interventions, such as urban development, seawalls, and jetties are placed for specific human benefits, their indirect effects on coastal economies, societies and ecosystems can be significant.
