TL;DR: Wang et al. as discussed by the authors investigated the effectiveness of virtual reality cycling as an intervention for physique improvement in simple obese college students and found that VR cycling is a more engaging and interesting intervention for fat loss and shaping than traditional aerobic exercise.
Abstract: Abstract Purpose The aim of this study was to investigate the effectiveness of Virtual Reality (VR) cycling as an intervention for physique improvement in simple obese college students. Methods A literature review, questionnaire survey, and 12-week experimental comparison were conducted using mathematical statistical methods on 41 simple obese college students in Nanjing, China. Results The results showed that 12 weeks of VR cycling had a significant effect on fat loss and shaping in simple obese college students. The weight, BMI, waist circumference, hip circumference, and waist-to-body ratio decreased by 5.25%, 5.22%, 4.44%, 2.44%, and 2.1%, respectively, while lung capacity increased by 9.15%. Significant differences were observed within 10%, 5%, and 1%. Moreover, there were gender-based differences in the morphological changes. Men's abdominal fat consumption was slightly greater than that of women, resulting in a significant reduction in the waist and buttocks of men compared to women. Conclusion The study concludes that VR cycling is a more engaging and interesting intervention for fat loss and shaping than traditional aerobic exercise. By adjusting the exercise time and course difficulty, participants are more likely to adhere to the exercise regimen, leading to significant weight loss and other positive outcomes. The results of this study could be useful for designing effective interventions to improve the physique of obese individuals.

TL;DR: Examples of the applications of the correlation coefficient have been provided using data from statistical simulations as well as real data.
Abstract: Correlation is a statistical method used to assess a possible linear association between two continuous variables. It is simple both to calculate and to interpret. However, misuse of correlation is so common among researchers that some statisticians have wished that the method had never been devised at all. The aim of this article is to provide a guide to appropriate use of correlation in medical research and to highlight some misuse. Examples of the applications of the correlation coefficient have been provided using data from statistical simulations as well as real data. Rule of thumb for interpreting size of a correlation coefficient has been provided.

TL;DR: The major influence for MSA is p, in agreement with theory; the joint main effect influences of p, q, and rfl to the total SSs remains greater than 84% under various choices of the levels of p.
Abstract: Kaiser's Measure of Sampling Adequacy (MSA) for factor-analytic correlation matrices is studied for several levels each of p, the number of variables, q, the number of factors, and rfl, the root-mean-square off-diagonal correlation. The major influence for MSA is p, in agreement with theory; the joint main effect influences of p, q, and rfl to the total SSs remains greater than 84% under various choices of the levels of p, q, and rfl.

TL;DR: Evidence-based practice includes, in part, implementation of the findings of well-conducted quality research studies, so being able to critique quantitative research is an important skill for nurses.
Abstract: Evidence-based practice includes, in part, implementation of the findings of well-conducted quality research studies. So being able to critique quantitative research is an important skill for nurses. Consideration must be given not only to the results of the study but also the rigour of the research. Rigour refers to the extent to which the researchers worked to enhance the quality of the studies. In quantitative research, this is achieved through measurement of the validity and reliability.1
Validity is defined as the extent to which a concept is accurately measured in a quantitative study. For example, a survey designed to explore depression but which actually measures anxiety would not be considered valid. The second measure of quality in a quantitative study is reliability , or the accuracy of an instrument. In other words, the extent to which a research instrument consistently has the same results if it is used in the same situation on repeated occasions. A simple example of validity and reliability is an alarm clock that rings at 7:00 each morning, but is set for 6:30. It is very reliable (it consistently rings the same time each day), but is not valid (it is not ringing at the desired time). It's important to consider validity and reliability of the data collection tools (instruments) when either conducting or critiquing research. There are three major types of validity. These are described in table 1.

16 Mar 2016TL;DR: The third edition of Bodyspace as discussed by the authors has been substantially revised to include new research and anthropometric surveys, the latest techniques, and changes in legislation that have taken place in recent years.
Abstract: In the 20 years since the publication of the first edition of Bodyspace the knowledge base upon which ergonomics rests has increased significantly. The need for an authoritative, contemporary and, above all, usable reference is therefore great. This third edition maintains the same content and structure as previous editions, but updates the material and references to reflect recent developments in the field. The book has been substantially revised to include new research and anthropometric surveys, the latest techniques, and changes in legislation that have taken place in recent years. New coverage in the third edition: Guidance on design strategies and practical advice on conducting trials Overview of recent advances in simulation and digital human modes Dynamic seating · Recent work on hand/handle interface Computer input devices · Laptop computer use and children’s use of computers · Design for an aging population and accessibility for people with disabilities · New approaches to risk management and new assessment tools, legislation, and standards As the previous two editions have shown, Bodyspace is an example of the unusual: a text that is a favorite among academics and practitioners. Losing none of the features that made previous editions so popular, the author skillfully integrates new knowledge into the existing text without sacrificing the easily accessible style that makes this book unique. More than just a reference text, this authoritative book clearly delineates the field of ergonomics.

TL;DR: A theoretical framework is presented, in which comfort and discomfort were defined and the hypothetical associations with underlying factors were indicated, and the literature was reviewed to determine the relationships between objective measures and subjective ratings ofcomfort and discomfort.
Abstract: The concepts of comfort and discomfort in sitting are under debate. There is no widely accepted definition, although it is beyond dispute that comfort and discomfort are feelings or emotions that are subjective in nature. Yet, beside several subjective methodologies, several objective methods (e.g. posture analysis, pressure measurements, electromyography (EMG) are in use to assess sitting comfort or discomfort. In the current paper a theoretical framework is presented, in which comfort and discomfort were defined and the hypothetical associations with underlying factors were indicated. Next, the literature was reviewed to determine the relationships between objective measures and subjective ratings of comfort and discomfort. Twenty-one studies were found in which simultaneous measures of an objective parameter and a subjective rating of comfort or discomfort were obtained. Pressure distribution appears to be the objective measure with the most clear association with the subjective ratings. For other variables, regarding spinal profile or muscle activity for instance, the reported associations are less clear and usually not statistically significant. ©Medline
