Influence of sex and limb dominance on lower extremity joint mechanics during unilateral land-and-cut manoeuvres

Limb dominance theory suggests that females tend to be more one-leg dominant and exhibit greater kinematic and kinetic leg asymmetries than their male counterparts, contributing to the increased risk of anterior cruciate ligament injury among female athletes. Thus, the purpose of this study was to examine the influences of sex and limb dominance on lower extremity joint mechanics during unilateral land-and-cut manoeuvres. Twenty-one women and 21 men completed land-and-cut manoeuvres on their dominant limb as well as their nondominant limb. Three-dimensional kinematics and kinetics were calculated bilaterally for the entire stance phase of the manoeuvre. Women performed land-and-cut manoeuvres with altered hip motions and loads as well as greater knee abduction at touchdown compared to men. Dominant limb land-and-cut manoeuvres where characterised by decreased hip flexion at touchdown as well as decreased hip flexion and adduction range of motion compared to nondominant land-and-cuts regardless of sex. The observed sex differences are consistent with previous research regarding mechanisms underlying the sex disparity in anterior cruciate ligament injury rates. However, observed differences regarding limb dominances appear somewhat arbitrary and did not suggest that the dominant or nondominant limb would be at increased risk of anterior cruciate ligament injury.  相似文献   

Short-term reliability of inflammatory mediators and response to exercise in the heat     

Joshua H. Guy  Andrew M. Edwards  Catherine M. Miller  Glen B. Deakin  David B. Pyne 《Journal of sports sciences》2017,35(16):1622-1628

Prospective application of serum cytokines, lipopolysaccharide (LPS), and heat shock proteins (eHSPs) requires reliable measurement of these biomarkers that can signify exercise-induced heat stress in hot conditions. To accomplish this, both short-term (7 day) reliability (at rest, n = 12) and the acute responsiveness of each biomarker to exercise in the heat (pre and post 60-min cycling, 34.5°C and 70% RH, n = 20) were evaluated. Serum was analysed for the concentration of C-reactive protein (CRP), interleukin-6 (IL-6), heat shock protein 72 (eHSP72), immunoglobulin M (IgM) and LPS. Test–retest reliability was determined as the coefficient of variation (CV). Biomarkers with the least short-term within-participant variation were IL-6 (19%, ±20%; CV, ±95% confidence limits (CL)) and LPS (23%, ±13%). Greater variability was observed for IgM, eHSP72 and CRP (CV range 28–38%). IL-6 exhibited the largest increase in response to acute exercise (95%, ±11%, P = < 0.001) and although CRP had a modest CV (12%, ±7%), it increased substantially post-exercise (P = 0.02, ES; 0.78). In contrast, eHSP72 and LPS exhibited trivial changes post-exercise. It appears variation of common inflammatory markers after exercise in the heat is not always discernible from short-term (weekly) variation.  相似文献   

Computerized Agility Training Improves Change-of-Direction and Balance Performance Independently of Footwear in Young Adults

Understanding the effects of training in different footwear on sporting performance would be useful to coaches and athletes. Purpose: This study compared the effects of computerized agility training using 3 types of footwear on change-of-direction and balance performance in young adults. Method: Thirty recreationally active young adults (M_age = 22.8 ± 3.1 years; M_height = 1.71 ± 0.7 m; M_bodymass = 73.4 ± 10.3 kg) were randomly assigned to a 6-week computerized agility training intervention in 1 of 3 footwear groups (n = 10/group): barefoot, minimal footwear, or traditional shoes. Participants had no previous barefoot or minimal-footwear training experience. Dependent variables included change-of-direction test time to completion, Star Excursion Balance Test, and single-leg stability evaluation. Testing was performed at the start of the training program, after 2 weeks, after 4 weeks, and at the end of the training program. Results: No group or time interactions were found for any of the dependent variables. Time main effects were observed for the performance measures of change of direction, Star Excursion, and single-leg-with-eyes-open stability evaluation. Participants improved in all 3 tests as early as 2 weeks into the intervention, with improvements continuing through the entire 6-week intervention. Conclusions: The lack of interaction and footwear effects suggests that agility and balance improvements during foot agility training are independent of footwear in a recreationally active young-adult population. Computerized agility training improves change-of-direction and balance performance within 2 weeks of training implementation. Future studies should consider footwear training effects in different populations, including frail older adults and athletes.  相似文献

Girls’ bodily activities in physical education How current fitness and sport discourses influence girls’ identity construction     

Kristin Walseth  Iselin Aartun  Gunn Engelsrud 《Sport, Education and Society》2017,22(4):442-459

Girls’ identity constructions are influenced by the dominant sport, health and beauty discourses in their society. Recent research indicates that sport and health discourses embedded in physical education (PE) compete for influence. Some of these studies have illustrated how these discourses inform girls’ social construction of body ideals and femininities, as well as their choices among physical activities. Our purpose in posing the question, ‘How are girls’ identity construction in PE influenced by current fitness and sport discourses?’ is to explore their identity construction and how they negotiate within the PE discourse as embodied subjects, as well as how they use their body as an object of display. This study is based on fieldwork among 10th grade students (15-year-olds) in a school in Oslo, Norway. The methods used include participant observation, informal conversations with the students and two group interviews. We hope that our findings concerning how sport and fitness discourses influence the students’ concepts of both the ideal body and their choices among bodily activities in PE will contribute to the debate on the future of PE. In particular, the girls’ embrace of the fitness discourse in PE is relevant to a question of great current concern: How should schools and PE teachers meet and relate to the fitness discourse in contemporary society? We believe that if left unchallenged and permitted to deepen its influence on PE, this discourse may well ensure that body modification becomes the primary purpose of PE.  相似文献   

Exergames ‘as a teacher’ of movement education: exploring knowing in moving when playing dance games in physical education     

Gunn Nyberg  Jane Meckbach 《Physical Education & Sport Pedagogy》2017,22(1):1-14

Background: A fundamental dimension of school physical education (PE) is arguably movement and movement activities. However, there is a lack of discussion in the context of PE regarding what can be called the capability to move in terms of coordinative abilities, body consciousness and educing bodily senses.

Purpose: This article explores and articulates what there is to know, from the mover's perspective, when knowing how to move in specific ways when playing exergames (dance games). Taking different ways of moving as expressing different ways of knowing as a point of departure, the following questions are the focus of this article: (i) How do students move when imitating movements in a dance game, and what different ways of knowing the movements can be described in the student group? (ii) What aspects of the movements are discerned simultaneously through the different ways of knowing the movements? (iii) What aspects seem critical for the students to discern and experience in order to know the movements in as complex a way as possible?

Design and analysis: The theoretical point of departure concerns an epistemological perspective on the capability to move as knowing how with no distinction between physical and mental skills, and also knowing as experiencing aspects of something to know. The data in this study comprise video recordings of students playing Nintendo Wii dance games in PE lessons in a compulsory school (for children aged between 7 and 16 years) in a small Swedish town. There were three PE lessons with four different stations, of which one was Nintendo Wii dance games (Just Dance 1 and 2). In total, the videoed material covers three 60-minute PE lessons, recorded during the autumn of 2012 and in which just over twenty students participated. In the study, we have used video observation as a data collection method. Jordan and Henderson maintain that video observation removes the gap between ‘what people say they do and what they, in fact, do’ (51). To conduct a systematic and thorough analysis of how the students experienced the avatar's movements, we looked for moments where all the students and the avatar could be simultaneously observed. Two video sequences were chosen, showing four students imitating two distinct and defined movements which constituted the basis for a phenomenographic analysis.

Conclusion: The result of the phenomenographic analysis shows different ways of knowing the movements as well as what aspects are discerned and experienced simultaneously by the students. In other words, these aspects also describe knowing in terms of discerning, discriminating and differentiating aspects of ways of moving. By examining a certain exergame's role ‘as a teacher,' we have emphasized the capability to move, from the mover's perspective, as an intrinsic educational goal of PE while highlighting the need for systematically planning movement education.  相似文献   

Measuring the value of theatre for Tyneside audiences     

Joshua Edelman  Maja Šorli 《Cultural Trends》2015,24(3):232-244

What values do theatre and dance hold for audience members? And how do these values differ between subsidised, amateur, and commercial performance? This paper addresses these questions through a survey of over 1800 spectators for theatre and dance in Tyneside in northeastern England, as well as a parallel set of focus groups, in the spring of 2014. These methods, which are designed for comprehensiveness and comparability, are being used across Europe by the Project on European Theatre Systems, a working group of theatre sociologists. Our research showed two sets of values which performances achieved; one was a common measure of performance quality, while the other described the values particular to subsidised work. This allows us to articulate both the general value of the arts and the particular values which subsidy (attempts to) facilitate. This has implications for both understandings of cultural value and for cultural policy, as the distinction between the two groups was not clean. We also found that amateur theatre participated in the same value system, but with an increased emphasis on loyalty and community cohesion. The paper concludes a methodological reflection on the use of quantitative methods in theatre studies.  相似文献
