TRUNK AND SHOULDER MUSCLE ACTIVITIES DURING PUSH-UP EXERCISE ON STABLE AND UNSTBLE SURFACES

The purpose of this study was to evaluate muscle activity of the prime movers and core stabilizers on stable and unstable surfaces during push-up exercise. Subject: Fourteen healthy male participants (age, 21.6 ±2.3 years; height, 174.7 ±8.1cm; weight, 68.2 ±16.4kg) without low back pain and shoulder injury in the past year were recruited. The participants completed push-up exercise in three conditions: on the ground, air disc and sling. EMG activities of external abdominal oblique, pectoralis major, and anterior deltoid muscles and elbow joint kinematics were recorded. Our results showed that external abdominal oblique muscle had significantly greater activity in the sling group (

Searching for rising stars in bibliography networks

Abstract. Identifying the rising stars is an important but difficult human resource exercise in all organizations. Rising stars are those who currently have relatively low profiles but may eventually emerge as prominent contributors to the organizations. In this paper, we propose a novel PubRank algorithm to identify rising stars in research communities by mining the social networks of researchers in terms of their co-authorship relationships. Experimental results show that PubRank algorithm can be used to effectively mine the bibliography networks to search for rising stars in the research communities
