Health benefits of Kung Fu: A systematic review

Abstract

The Chinese martial arts (Kung Fu) have existed for centuries and are generally accepted as being beneficial for health without much empirical data. The aim of this systematic review was to assess the health effects of “hard” Kung Fu styles by performing electronic and manual searches of the literature. The aspects of health and the Kung Fu style examined varied between most studies; in some cases, the martial art group consisted of practitioners of other martial art styles also. Of 2103 references identified, only nine papers were eligible and reviewed. All were observational studies, observing a range of health aspects possibly related to Kung Fu training or performance. Our findings suggest that there is no evidence that Kung Fu practice is associated with the prevention or treatment of any health condition. However, as a moderate- to high-intensity form of aerobic exercise, it may confer benefits similar to those attributed to other aerobic training modalities. However, this hypothesis remains to be tested in clinical trials. Physiological benefits (e.g., aerobic capacity and bone density) may be associated with long-term Kung Fu practice. Future research in this area should adopt experimental designs, clearly identifying eligibility criteria, testing and training protocols, and include health-related outcomes and documentation of adverse events, to advance knowledge in this field.     

A Comparison of Video and Text-Based Questionnaire Methods for Testing Older Adults

Abstract

The purpose of this study was to initiate systematic research on dance as a creative and expressive art form. Although the process of expression through movement has concerned dancers and dance teachers for some time, there have been few attempts at a systematic analysis of either the process or the product of dance expression. Dance has generally been considered immeasurable because of its peculiarities as an art form.

While there is little apparent value in quantitative measurement of dance, qualitative measurement appears to have considerable value. It can sharpen the focus on principles of dance composition, contribute toward increased teaching effectiveness, enlarge dance's expressive range, and increase its ability to communicate.

Specifically, this study attempted to determine how effectively modern dance communicates by using a systematic analysis of individual dance compositions. Samples of dance studies with specific intentions were choreographed and filmed. The dances were then viewed and evaluated by a selected and trained jury on (a) their ability to communicate emotional and physical qualities, (b) the type and structure of their composition, and (c) their choreographic and artistic effectiveness.

Results of this study showed that least agreement was reached by the jurors in rating the dances according to structural strength and in identifying their composition type. Realistic vehicles of expression were more easily recognized than were abstract ones. There was substantial agreement on the emotion communicated by each composition. Presence of all the traditional dance elements appears unnecessary for effective communication.

云南中小学教师人格特征及影响因素研究

以探讨云南中小学教师人格特征及影响因素为目的,用团体施测方法对 199名中小学教师的人格特征进行评定,得出了受测教师在乐群性、兴奋性、敢为性、幻想性、忧虑性、自律性等方面高于其它专业技术员,而在紧张性、怀疑性、独立性上得分则低于后者;中、小学教师仅在乐群、兴奋、敏感得分上存在显著差异;不同性别教师在一半以上因素中得分存在显著差异;不同教龄和科目的教师也存在一定差异的结果.从而认为中小学教师人格具有较高的一致性,教师人格的健全发展是提高教师心理素质的前提条件.     

The Unexpected for the Expecting Parent: Effects of Disruptive Early Interactions on Mother–Infant Relationship

SYNOPSIS

High-quality parental caregiving promotes children’s development from their day of birth or even earlier. Whether there are ways to predict, and ultimately enhance, parental caregiving quality during the prenatal stages of development has been less well understood. This circumstance is even truer when things do not go according “to plan.” In this commentary, we explore two possible scenarios, perhaps unexpected for expectant parents, that can affect children’s development: (1) postpartum parental displays of atypical behaviors and parental caregiving strategies (i.e., maternal/paternal depression) and (2) postpartum child displays of atypical behaviors (i.e., autism spectrum disorder).

Effects of learning styles on learners’ collaborative patterns in a mobile-assisted,Chinese character-forming game based on a flexible grouping approach

This paper reports a novel, mobile-assisted, game-based learning design for Chinese character learning. In playing the ‘Chinese-PP’ game in a 1:1 (one-device-per-student) setting, each of the 31 target students in Primary 3 (9 years old) is assigned a Chinese character component. A student may make use of his/her own and peers’ character components to form a legitimate Chinese character, and invite the peers with matching components to join his/her group. The intention is to assist the students in developing general orthographic awareness (understanding the structures of Chinese characters) through social negotiation. In this paper, the students’ collaborative learning processes in three game sessions were analysed. The relationships between students with varied learning styles and their game behaviours and learning gains were unveiled as a result. Through the Chinese-PP learning activities that stimulated active peer coaching and social learning, we found that all the target students became active learning participants and achieved high learning gains in the last game session. Recommendations for the future development of such a novel learning approach will also be given.
