Acute effects of different warm-up protocols on highly skilled golfers’ drive performance     

Ben L. Langdown  Jack E.T. Wells  Sean Graham  Matt W. Bridge 《Journal of sports sciences》2019,37(6):656-664

Previous research has highlighted the positive effect that different warm-up protocols have on golf performance (e.g. Sorbie et al., 2016; Tilley & Macfarlane, 2012) with the design of warm-ups and programmes targeting and improving golf performance through the activation and development of specific muscle groups. This study aimed to examine the acute effects of two warm-up protocols on golf drive performance in comparison to a control condition. Using a randomised counterbalanced design over three testing sessions, twenty-three highly skilled golfers completed the control, dynamic and resistance-band warm-up conditions. Following each condition, a GC2 launch monitor was used to record ball velocity and other launch parameters of ten shots hit with the participants’ own driver. A repeated-measures ANOVA found significant increases in ball velocity (η_p² = .217) between the control and both the dynamic and resistance-band warm-up conditions but no difference between these latter two, and a reduction in launch angle between control and dynamic conditions. The use of either a dynamic stretching or resistance-band warm-up can have acute benefits on ball velocity but golfers should liaise with a PGA Professional golf coach to effectively integrate this into their golf driving performance.  相似文献   

The construction of women’s social spaces through physical exercise in urban China     

Huan Xiong 《Sport in Society》2019,22(8):1415-1432

Abstract

By applying feminist geographical theories and qualitative research methods, this article reveals Chinese women’s exercise experiences in urban spaces and discusses how women, through physical activity in neighbourhoods, public places and commercial facilities, constructed social spaces of their own. The findings show that exercise spaces are potentially sites for women’s health, well-being, social networking and collective empowerment. They challenge traditional gendered urban spaces by deconstructing the dual structure of ‘public’ and ‘private’ spheres, inducing women to gradually shift from the ‘edge’ to the ‘centre’. Though the spatial differences in women’s physical activities reflect the diversity and dynamics of women’s spatialities, they also imply the continuous social powers on women in exercise fields, where gendered disparities and class stratification may be sustained.  相似文献   

锻炼社会支持量表的编制与信效度检验          下载免费PDF全文

钟涛  胡亮  刘献国 《体育科研》2019,(6):42-17

有规律的体育锻炼对人们的身心健康具有积极的促进作用，而社会支持是影响锻炼行为的重要相关因素。因此本研究的目的在于编制和检验锻炼社会支持量表。通过结合现有研究文献和质性研究，确立了初测量表，并通过两轮定量研究，应用探索性和验证性因子分析，信度分析以及校标效度检验对该量表进行了标准化的信效度检验。结果表明锻炼社会支持量表由4个因子构成，即情感性支持、信息性支持、工具性支持、同伴性支持，共24个条目。统计分析显示，量表具有良好的结构效度、内部一致性、重测信度和校标效度。锻炼社会支持量表符合我国文化背景，可以作为在中国人群中进行锻炼社会支持测量的工具。  相似文献   

Acute fatigue negatively affects risk factors for injury in trained but not well-trained habitually shod runners when running barefoot     

Nicholas Tam  Devon R. Coetzee  Safwaan Ahmed  Robert P. Lamberts  Yumna Albertus-Kajee  Ross Tucker 《European Journal of Sport Science》2017,17(9):1220-1229

Introduction: Many factors may contribute to running-related injury. These include fatigue and footwear, the combination of which has rarely been studied, in particular with reference to barefoot running, recently advocated as a method to reduce injury risk. Methods: Twenty-two runners (12 well-trained and 10 trained) participated in a 10?km fatiguing trial. Knee and ankle joint kinematics and kinetics and electromyography were assessed during overground running in the barefoot and shod condition. This was performed pre- and post-fatigue using a motion capture system and force platforms. Results: Initial loading rate increased in the trained runners when barefoot but not shod. Shod knee stiffness increased in both groups after fatigue, whereas barefoot knee stiffness decreased only in the trained group. A reduction in barefoot bicep femoris pre-activation was found in both groups. During stance, a reduction in vastus lateralis and biceps femoris and an increase in tibialis anterior activity were found over time in both groups and conditions. Trained runners decreased gluteus medius and increased lateral gastrocnemius median frequency for both conditions after fatigue. Conclusion: When fatigued, gait adjustments in habitually shod runners may increase injury risk when running barefoot. Training status may be a risk factor for injury, as less-trained runners experience muscular fatigue changes that may compromise ground reaction force attenuation. Caution is recommended when transitioning to pure barefoot running.  相似文献   

甲烷水对一次性力竭运动所致大鼠心肌损伤的保护作用     

王茜  辛磊  陈笑欢  胡静芸  娄淑杰 《北京体育大学学报》2017,40(7):43-48

摘要：目的：观察灌服甲烷水对一次性力竭运动所致大鼠心肌缺血性损伤、心脏组织内氧化应激和炎症因子的影响，探讨其对运动性心肌损伤产生保护作用的可能机制。方法：24只雄性SD大鼠随机分为安静对照组（C组）、运动对照组（EP组）、运动甲烷水组（EM组）。EP组和EM组分别于运动前30 min灌服蒸馏水和甲烷水，之后进行一次性力竭跑台运动。采用化学比色法、ELISA和Luminex xMAP?技术（液态悬浮芯片技术）检测大鼠血清和心肌中生化指标。结果：1）EM组较EP组运动时间显著延长（P<0.01）。2）与C组比较，EP组大鼠血清中IL-1β、IL-6含量极显著升高（P<0.01），心肌eNOS水平显著降低，MDA含量显著升高（P<0.05），3-NT含量极显著性升高（P<0.01）；与EP组比较，EM组血清中cTnI水平显著上升，IL-1β、IL-6含量显著下降（P<0.05），大鼠心肌eNOS水平显著升高（P<0.05），SOD活性、T-AOC含量极显著上升（P<0.01），MDA含量、3-NT含量显著降低（P<0.05）。结论：灌服甲烷水提高大鼠运动能力，可能是通过增加心肌eNOS水平，催化NO生成，舒张血管；提高心肌抗氧化能力，改善大鼠心肌氧化应激损伤，从而对运动性心肌损伤具有一定的保护作用。  相似文献
