Physiological and Psychophysical Comparison between a One and Two-Handed Identical Lifting Task
The 1991 NIOSH (National Institute for Occupational Safety and Health) revised lifting equation’s objective is to prevent or reduce lifting-related injuries, especially of the low back. However, the lifting equation is only applicable to two-handed lifting tasks. Oneand twohanded repetitive lifting tasks are a consistent part of many occupations. Understanding the metabolic demands of oneand tw...
متن کاملThe Kinematics of Trunk and Upper Extremities in One-Handed and Two-Handed Backhand Stroke
The aim of this study was to present kinematics of trunk and upper extremities in tennis players who perform one-handed and two-handed backhand strokes. The study aimed to address the question of whether one of those techniques has some important advantage over the other. If so, what makes it superior? The study included 10 tennis coaches with average coaching experience of 9 years. The coaches...
متن کاملComparison of surgically induced astigmatism between one-handed and two-handed cataract surgery techniques
BACKGROUND The purpose of this study was to compare surgically induced astigmatism (SIA) between one-handed and two-handed cataract surgery techniques. METHODS Eighty-eight eyes of 44 patients with no ocular disease other than cataract, who underwent cataract surgery by a single surgeon, were selected for this study. Cataract surgery was performed by coaxial phacoemulsification and intraocula...
متن کاملOne and two-handed backhand executed in different kinematic chains
Tennis is numbered among technically complex sports disciplines, where a variety of shots considerably affects the results obtained by professional players. According to the references worldwide, tennis players should master four areas: technical, tactical, physical and mental ones [1]. One of the most essential elements of technical training is backhand, which can be performed with one or two ...
متن کاملTwo-Handed Assembly Sequencing
This paper considers the computational complexity of automatically determining assembly sequences for mechanical products. Specifically, we address the partitioning problem: given an assembly of rigid parts, identify a proper subassembly that can be removed as a rigid object without disturbing the rest of the assembly. We examine the complexity of the partitioning problem under varying types of...
