STUDY DESIGN Prospective descriptive biomechanical analysis of shoulder motion in golf. OBJECTIVE To characterize normal shoulder motion during the driving swing in male recreational golfers of various age groups. BACKGROUND Shoulder trauma accounts for approximately 12% of all golf-related injuries. To design sport-specific rehabilitation programs for the injured golfer and exercise progra...

the human population has been growing at least at the rate of 1.2% annually since 1960 reachingup to 6.4b in 2002 and more than 7.0b in 2012. in davao city, the annual population growth rate is running at 3.22%in year 1990, at 2.41% last 2007 and recently in 2013 at 2.36%. the alarming problem we confront today is thatthe increase in land area for human use does not expand in proportion to popu...

The classic Herlihy/Wing notion of concurrent objects has had great success in theories and implementations (e.g. java.util. concurrent), providing programmers with the simple abstraction of an atomic object. Since then, software transactions have appeared, also touting the the goal of providing an atomicity abstraction. However, despite some vertical composition strategies within particular ST...

INTRODUCTION Although parachute landing injuries are thought to be due in part to a lack of exposure of trainees to realistic descent velocities during parachute landing fall (PLF) training, no research has systematically investigated whether PLF technique is affected by different vertical descent conditions, with standardized and realistic conditions of horizontal drift. This study was designe...

A wireless network of buoys, two autonomous robotic boats, and an autonomous tethered vertical profiling system were used to characterize phytoplankton dynamics and spatiotemporal changes in chemical and physical forcing factors in a small montane lake (Lake Fulmor, Idyllwild, California). Three deployments each year were conducted in 2005 and 2006 to examine seasonal changes in the structure o...

STUDY DESIGN Single-subject with repeated measures. OBJECTIVES To determine if runners can use real-time visual feedback from an accelerometer to achieve immediate reductions in tibial acceleration and vertical-force loading rates. BACKGROUND Stress fractures are a common injury among runners. Previous studies suggest that runners with higher than normal tibial acceleration and vertical-for...
