中国共产党成立后,昭通青年学生纷纷加入中国共产党的党团组织,从事推翻三座大山革命活动。1928年1月昭通历史上第一个共产党组织——中共昭通支部成立,昭通人民在地下党组织的领导下,进行了不屈不挠的革命斗争,终于在1950年3月迎来昭通解放。 相似文献

建国初期的戏曲改革运动,极大地推动了戏曲艺术的发展。它在催生新剧的同时,也极力改编旧剧,使戏曲艺术以一种全新的面貌呈现在人民大众面前。根据明代康海所作杂剧《中山狼》改编的新剧,就很好地体现了戏曲改革运动的指导思想。研究该剧新旧剧本的异同,能够帮助我们更加全面地认识建国初期的戏曲改革运动。 相似文献

19世纪末20世纪初,美国处于重大的社会转型时期,伴随着社会转型,社会各领域产生了一系列的问题,为解决这些社会问题,美国兴起了社会调查运动。受社会调查运动的影响,学校调查运动也开展起来,并成为社会调查运动的重要组成部分。在学校追求效率和教育寻求科学化的背景下,学校调查运动发展迅猛,对美国教育产生了重要影响。 相似文献

对日本近代文学中的"言文一致"运动的研究可以分为两个阶段,第一阶段的研究是对其做出了高度评价,第二个阶段是在对日本明治时期的"言文一致"运动所进行的综合性研究的前提下所产生,并使之走下主流位置。对明治时期的"言文一致"运动以及日本近代文学的文体改革所具备的性质进行探讨可以清楚其走下主流位置的根本原因。 相似文献

东盟区域龙狮运动传播过程中伦理困境的解决是促进龙狮运动在国际上传播的重要影响因素。面对传播者的行为瓶颈问题,应从提高传播者的道德意识做起;面对传播媒介沦陷的问题,应注意龙狮运动传播媒介作用的正确发挥;面对中西方文化差异问题,应促进各国文化的融合;面对受众对龙狮运动的误解,应扩大对龙狮运动的正面宣传。深入解决龙狮运动传播的伦理困境,加快龙狮文化的国际传播脚步。 相似文献

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 (ηp2 = .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

Leg amputation side determines performance in curve sprinting: a case study on a Paralympic medalist

The lower limb kinetics of curve sprinting in amputees are not well described in the literature, particularly with respect to the effect of the side of amputation. This is an issue due to the importance of the knowledge for prosthetic design and classification of athletes. Thus, the aim of this study was to investigate the influence of side of amputation on curve sprinting performance in athletes with a unilateral leg amputation. A three-dimensional motion analysis system (Vicon), four force plates (Kistler) and a modified mathematical human model (ALASKA) were used to compare clockwise and counter clockwise curve sprinting lower limb kinematics and kinetics of a Paralympic medalist with a left-sided knee exarticular amputation. Results reveal that vertical ground reaction force application and total vertical impulse were lower when the affected limb was at the inside of the curve. The unaffected limb showed joint mechanics different to those established for non-amputee athletes and might contribute better to propulsion when being the inside limb. Curve sprinting biomechanics and the ability to attain high radial velocities are directly dependent on the side of amputation relative to the curve direction in a unilateral amputee athlete of highest performance level. 相似文献

Based on technological and analytical advances, the capability to more accurately and finitely examine biomechanical and skill characteristics of movement has improved. The purpose of this study was to use Inertial Measurement Units (IMUs) and Functional Principal Components Analysis (fPCA) to examine the role of movement variability (assessed via angular velocity), on 2 divers (1 international level; 1 national) performing the forward 3½ pike somersault dive. Analysis of angular velocity curves during ive-flight identified 5 fPCs, accounting for 96.5% of movement variability. The national diver’s scatter plots and standard deviation of fPC scores illustrated larger magnitudes of angular velocity variability across dive flight. For fPC1 and fPC3, magnitudes of SD variability were 282.6 and 201.5, respectively. The international diver illustrated more consistent angular velocity profiles, with clustering of fPCs scores (e.g., fPC1 & 3 = SD’s of 75.2 & 68.0). To account for lower variability in the international diver, the ability to better coordinate movement sequences and functionally utilise feedback in response to initiation of the somersault position is highlighted. Overall, findings highlight how both IMUs and fPCA can more holistically and finitely examine the biomechanical and skill characteristics of movement sequences with the capability to inform athlete development. 相似文献

This study aimed to determine the suitability of the load-velocity relationship to prescribe the relative load (%1RM) in women, as well as to compare the load-velocity profile between sexes and participants with different strength levels. The load-velocity relationship of 14 men (1RM: 1.17 ± 0.19) and 14 women (1RM: 0.66 ± 0.13) were evaluated in the bench press exercise. The main findings revealed that: (I) the load-velocity relationship was always strong and linear (R2 range: 0.987–0.993), (II) a steeper load-velocity profile was observed in men compared to women (Effect size [ES]: 1.09), with men showing higher velocities for light loads (ES: ? 0.81 and ? 0.40 for the y-intercept and 30%1RM, respectively), but women reporting higher velocities for the heavy loads (ES: 1.14 and 1.50 at 90%1RM and 100%1RM, respectively); and (III) while the slope of the load-velocity profile was moderately steeper for weak men compared to their strong counterpart (ES: 1.02), small differences were observed between strong and weak women (ES: ? 0.39). While these results support the use of the individual load-velocity relationship to prescribe the %1RM in the bench press exercise for women, they also highlight the large disparities in their load-velocity profile compared to men. 相似文献
