background and objectives: evaluation has an important role in software development. quality is considered in the evaluation of information systems, which depends on usability, availability, validity, compatibility, and response time. this research was performed with the aim of determining the usability of hospital information systems according to the 7 principles of isometric 9241, part 10. me...

The purpose of this study was to investigate the between-session reliability of common strengthand power-related measures in adolescent athletes. Seventeen adolescent athletes (males: n = 8: age 17.1 ± 2.2 years; height 175.6 ± 3.5 cm; mass 80.2 ± 3.6 kg; females: n = 9; age 16.9 ± 2.6 years; height 178.5 ± 4.3 cm; mass 71.5 ± 4.5 kg) participated in this study. Isokinetic dynamometry, isometri...

The authors modeled variability of force during continuous isometric contractions of the quadriceps femoris. Twenty adults (aged 25 +/- 6 years old) performed isometric leg extensions. Target forces were 11 percentages of maximum voluntary contraction (%MVC), ranging from 2 to 95%, and 5 absolute levels, from 25 to 225 N. The authors used standard deviation of absolute force, coefficient of var...

It is established that there exists an intimate connection between isometric deformations of polyhedral surfaces and discrete integrable systems. In particular, Sauer’s kinematic approach is adopted to show that second-order infinitesimal isometric deformations of discrete surfaces composed of planar quadrilaterals (discrete conjugate nets) are determined by the solutions of an integrable discr...

The purpose of this study was to examine the effects of Taiji training on knee extensor strength and force control in older individuals. Twenty-six healthy older adults (71.9 6 1.8 years) participated in the study. Sixteen of the older adults (70.2 6 1.8 years) underwent Taiji training for 20 weeks (experimental group), whereas the other 10 (74.6 6 1.2 years) served as the control group. For bo...

OBJECTIVE To determine if isometric (static) strength accurately predicts dynamic lifting capacity. PARTICIPANTS 107,755 male and 23,078 female prospective workers taking part in a post-offer employment test. METHODS Subjects were tested for strength three standard static lifts and attained physical maxima for four dynamic lifts. RESULTS The data confirms modest correlations between isome...
