Systematically review the comparison of anterior and posterior framed walker in terms of biomechanical analysis and energy expenditure and to discuss the implications for clinical practice. A systematic literature search was performed to identify studies that evaluated the gait pattern, upper extremity (UE) kinetics and kinematics and energy…

Analogies are useful tools instructors can use to help make challenging concepts less abstract by drawing connections to familiar contexts. In this paper we provide an overview of the various analogies published in the education literature that are situated in the context of enzyme kinetics, including narrative-based analogies (analogies intended…

Peak oxygen uptake (VO[subscript 2]) is internationally recognized as the criterion measure of youth aerobic fitness, but despite pediatric data being available for almost 80 years, its measurement and interpretation in relation to growth, maturation, and health remain controversial. The trainability of youth aerobic fitness continues to be hotly…

Jensen's scheme for the logical structure of chemistry is taken as reference to study the logical structure of physical chemistry. The scheme distinguishes three dimensions (composition and structure, energy, and time), with each dimension treated at one of the three levels (molar, molecular, and electrical). Such a structure places the outer…

The purpose of this study was to document the top journals classified in the area of kinesiology in three bibliometric databases and the associations between the main bibliometric indicators reported through them. The Thomson Reuters Journal Citation Reports was searched for journals indexed (n = 85) in the sport sciences category for 2011.…

We review literature on the teaching and learning of chemical kinetics at both the secondary and tertiary levels. Our aim in doing so is to summarize research literature, synthesize recommendations for future research, and suggest implications for practitioners. Two main bodies of literature emerged from the chemical kinetics education research:…

Researchers and practitioners alike express concerns about the conceptual difficulties associated with the concepts of momentum and kinetic energy currently taught in school physics. This article presents an in-depth analysis of the treatment given to them in 44 published textbooks written for UK secondary school certificate courses. This is set…

Reviews the effects of open kinetic chain (OKC) and closed kinetic chain (CKC) exercise on anterior cruciate ligament (ACL) strain and patellofemoral joint stress, suggesting a combination of the two for quadriceps strengthening after ACL reconstruction. Both OKC and CKC exercises may be modified and implemented for quadriceps strengthening after…

Past and recent developments and future directions in kinesiology and biomechanics are reviewed. Similarities and differences between these two areas are clarified. The areas of kinesiology and biomechanics have distinct unique qualities and should be treated as separate disciplines. (CJ)

Simple observation of dance movement, while very useful, can lead to misconceptions, about the physical realities of dance movement, that make learning difficult. This gap between reality and understanding can be reduced by the application of biomechanical techniques such as cinematography, electromyography, and force-plate analysis. Biomechanical…

Reviews literature dealing with novel developments or important trends in electrochemistry. Areas examined include mass transfer, electrode kinetics, surface effects, chemically modified electrodes, coulostatic/galvanostatic methods, bioelectrochemistry, spectroelectrochemistry, and electrode instrumentation. Books, textbooks, and literature…

Dance has become a major force of expression among Hispanics in the United States serving the functions of ethnic unity, identity, and cultural expression. As a result, it is increasingly important to define and understand its development and history. This paper provides a universal definition of ethnic dance and a theoretical base upon which to…

Oxygen uptake and heart rate kinetics for submaximum exercise (bicycle riding) were compared in prepubescent boys and adult men. Resulting data suggest that children and adults do not differ significantly in cardiorespiratory adjustments during low-intensity exercise. (Authors/PP)

A greater role for the history and philosophy of science in science education can only be realized if it is based on both a credible analytical approach--such as that of Lakatos--and if the evolution of a sufficient number of major themes in science is known in suitable detail. Considers chemical kinetics as an example topic. Contains 62…

Describes advances in catalytic determinations and other applications of kinetics in chemical analysis. A section on instrumentation and computers is included. Cites 158 references. (CS)
