The aim of this study was to assess the eating habits of Korean wrestlers, and to explore the impact of differences in dietary intake on power output performance and blood lactate concentrations. Thirty adult wrestlers with more than seven years of experience each were included, grouped according to their competitive level (national, senior, and university team level). Participants recorded their dietary intake for seven days; nutritional analysis was performed using the CAN-Pro 4.0 software. After the nutritional survey, power output performance (Wingate test) was evaluated and blood parameters, including lactate concentration, were assessed. The wrestlers’ dietary assessments revealed differences in carbohydrate, protein, and fat intake among the groups, as well as differences in the peak power, mean power, and change in peak power, obtained from the Wingate test. Finally, the senior group had a significantly higher and lower lactate concentration than the university group immediately post training and 30 minutes post training, respectively. Follow-up studies should reveal more accurate associations between nutritional intake, nutritional quality, and performance. Finally, considering a study concerning nutrition and weight loss based on the results from this study, including not only wrestlers but also combat sport athletes will benefit nutrition education as well as athletes’ intake and performance.
本研究的目的是评估韩国摔跤运动员的饮食习惯,并探讨饮食摄入量的差异对力量输出表现和血乳酸浓度的影响。30名有7年以上经验的成年摔跤手被包括在内,根据他们的竞技水平(国家、高级和大学团队水平)分组。参与者记录了他们7天的饮食摄入量;采用CAN-Pro 4.0软件进行营养分析。营养调查结束后,评估功率输出性能(Wingate试验),并评估血液参数,包括乳酸浓度。摔跤运动员的饮食评估揭示了各组之间碳水化合物、蛋白质和脂肪摄入量的差异,以及从温盖特测试中获得的峰值功率、平均功率和峰值功率变化的差异。最后,老年组乳酸浓度显著高于大学组,训练后30分钟乳酸浓度显著低于大学组。后续研究将揭示营养摄入、营养质量和运动表现之间更准确的联系。最后,根据本研究的结果,考虑一项关于营养与减肥的研究,不仅包括摔跤运动员,而且包括格斗运动运动员,都将受益于营养教育,以及运动员的摄入量和表现。

Though the role of emotion has been largely acknowledged across most consumer settings, only recently has this interest transferred to the various contexts in which sports are consumed. The purpose of the present research is to highlight the role of emotions during the viewing of televised sports programming. Across two studies, the manifestation of emotional arousal is empirically established. Additionally, the emotional valence (i.e., the extent to which a stimulus is perceived as affectively positive, neutral, or negative) of marketing stimuli are assessed. A methodology for measuring baseline levels of emotional valence for commercial advertising is outlined. Study 1 is presented in which empirical support is established for the fleeting influence that live sports consumption has upon emotional arousal. This is followed by a review of Study 2, which establishes a methodology for measuring the emotional valence perceived by consumers for embedded commercial advertising. Finally, the practical and research implications of these findings are discussed.
尽管情感的作用已经在大多数消费者环境中得到了很大程度上的承认,但直到最近,这种兴趣才转移到体育消费的各种环境中。本研究的目的是为了强调情绪在观看电视体育节目中的作用。在两项研究中,情绪唤起的表现是经验建立的。此外,还评估了营销刺激的情感效价(即,刺激在情感上被视为积极、中性或消极的程度)。本文概述了一种测量商业广告情绪效价基线水平的方法。研究1为现场体育消费对情绪唤醒的短暂影响提供了实证支持。接下来是对研究2的回顾,研究2建立了一种测量消费者对嵌入式商业广告感知的情感效价的方法。最后,讨论了这些发现的现实意义和研究意义。

The purpose of this study was to investigate the effect of combined static and dynamic stretch as part of warm-up procedures on isokinetic strength, functional movement screen (FMS), flexibility, and agility in Korean national foil fencers. Twelve Korean fencers (mean age 29.3±3.6yrs, Career: 16.6±3.1yrs, Height: 171.4±9.5cm, Weight: 67.3±12.4kg) participated in this study (Male: 7, age 30.0±3.2yrs, Career: 16.7±2.2yrs, Height: 177.1±8.1cm, Weight: 75.1±9.9kg; Female: 5, age 28.4±4.4yrs, Career: 16.4±4.3yrs, Height: 163.4±3.9cm, Weight: 56.3±4.1kg). Fencers measured FMS, isokinetic strength of knee joint, flexibility, agility at pre (1-week) and post (4-week). Fencers performed a warm-up program three times a week for four weeks. As a results, FMS scores (11.8±2.3 to 14.4±1.6, p<0.05), strength of dominant knee flexors (115.5±26.0 to 126.0±26.6, p<0.05), change-step jump (66.0±6.8 to 69.4±5.6, p<0.05), trunk forward flexion (12.0±7.7 to 13.9±6.5, p<0.05) were significantly higher in post-test than pre-test, respectively. However, the results for front-rear step, trunk backward extension were not significant differences between pre-test and post-test. These results suggest that the fencing-specific warm-up program based on stretching is effective on strength of knee flexors, agility by increasing flexibility, improving stability, mobility.
本研究的目的是探讨静态和动态联合拉伸作为热身程序的一部分对韩国国家花剑运动员等速力量,功能运动屏幕(FMS),柔韧性和敏捷性的影响。研究对象为12名韩国击剑运动员,平均年龄29.3±3.6岁,职业生涯16.6±3.1岁,身高171.4±9.5cm,体重67.3±12.4kg(男7名,年龄30.0±3.2岁,职业生涯16.7±2.2岁,身高177.1±8.1cm,体重75.1±9.9kg;女5岁,年龄28.4±4.4岁,职业16.4±4.3岁,身高163.4±3.9cm,体重56.3±4.1kg。在实验前(1周)和实验后(4周)分别测量FMS、膝关节等速力量、柔韧性、敏捷性。击剑运动员每周进行三次热身训练,持续四周。结果:测试后FMS评分(11.8±2.3 ~ 14.4±1.6,p<0.05)、优势屈膝肌力(115.5±26.0 ~ 126.0±26.6,p<0.05)、变步跳(66.0±6.8 ~ 69.4±5.6,p<0.05)、躯干前屈(12.0±7.7 ~ 13.9±6.5,p<0.05)均显著高于测试前。而前后步、躯干后伸在测试前与测试后差异不显著。这些结果表明,以拉伸为基础的击剑专项热身计划对膝关节屈肌的力量和敏捷性是有效的,通过增加柔韧性,改善稳定性和机动性。

This study examined the effects of an eight-week neuromuscular training (NMT) program on knee valgus angle in African American female athletes. Twenty-six female collegiate athletes participated. NMT group (n=15, 19.6±1.12 years) underwent an intervention training program that included three main components (plyometric and movement, core strengthening and balance, and resistance training). While, control group (n=11, 19.3±1.50 years) underwent the resistance training protocol for eight weeks. We hypothesized the NMT program would significantly decrease knee valgus angles during a drop vertical jump (DVJ) at landing for the NMT group when compared to the control group. Wilcoxon signed rank tests were done on the Pre-and Post-test findings. Results showed maximum valgus angle (VGmax) is significantly decreased (p<.05), and Maximum flexion (Flexmax) is significantly increased during the drop vertical jump in dominant leg (p<.05). The results support the hypothesis that an 8-week NMT program that combines injury prevention-training components can decrease an injury risk factor such as knee valgus in African American female athletes.
本研究考察了为期八周的神经肌肉训练(NMT)对非裔美国女运动员膝关节外翻角的影响。26名女大学生运动员参加了比赛。NMT组(n=15, 19.6±1.12年)接受干预训练计划,包括三个主要组成部分(增强运动和运动,核心强化和平衡,阻力训练)。对照组(n=11, 19.3±1.50岁)进行8周阻力训练。我们假设,与对照组相比,NMT方案可以显著降低NMT组在落地时垂直起跳(DVJ)时的膝外翻角度。对测试前和测试后的结果进行了Wilcoxon符号秩检验。结果显示,优势腿下降垂直跳时最大外翻角(VGmax)显著降低(p< 0.05),最大屈曲度(Flexmax)显著增加(p< 0.05)。研究结果支持了一个假设,即一个8周的NMT项目结合了损伤预防和训练的成分,可以减少非裔美国女运动员的损伤风险因素,如膝关节外翻。

Lumbar Disc Injury: Mechanisms and Intervention Options 腰椎间盘损伤:机制和干预选择
Pub Date : 2021-12-31 DOI: 10.24985/ijass.2021.33.2.140
Jim F. Schilling
Low back pain is prevalent in sport and the lumbar disc is a pain generator. Conservative care of these physically demanding patients is not consistent as outcome data has not established optimal strategies. Investigating disc injury mechanisms using experimental models will contribute to the creation of treatment strategies that will take into effect movements to avoid and minimize to reduce unwanted strain on the injured tissues throughout the recovery process. Additionally, how disc tissue acquires nutrition would help provide insight into activities that may facilitate the ability of disc tissue to sustain health and promote optimal healing. Rotational forces and compression in trunk-flexed positions may inflict injury to the annulus and endplate structures. Activity to facilitate nutrients through the endplate into the nucleus of the disc and restriction of exasperating movements may be effective in returning athletes to their desired levels of performance efficiently. The purpose of this review is to inquire possible disc injury mechanisms and how they occur in sport. It will also address recommendations for treatment interventions based on disc healing and metabolism evidence.
腰痛在运动中很普遍,腰椎间盘是疼痛的产生者。这些体力要求高的患者的保守治疗不一致,因为结果数据没有建立最佳策略。利用实验模型研究椎间盘损伤机制将有助于制定治疗策略,从而在整个恢复过程中有效地避免和最大限度地减少受伤组织的不必要压力。此外,椎间盘组织如何获得营养将有助于深入了解可能促进椎间盘组织维持健康和促进最佳愈合能力的活动。躯干屈曲位置的旋转力和压缩可能对环空和终板结构造成损伤。促进营养物质通过终板进入椎间盘核的活动和限制令人恼火的运动可能有效地使运动员恢复到他们期望的表现水平。本综述的目的是探讨可能的椎间盘损伤机制及其在运动中是如何发生的。它还将提出基于椎间盘愈合和代谢证据的治疗干预建议。

The aim of the present study was to document the process of Long-term Athlete Development (LTAD) adoption by Canadian sport coaches, and to identify predictors of: 1) their attitude and intention to adopt such a social innovation, and 2) their LTAD adoption level. Using Rogers’ innovation diffusion theory, a survey of 499 Canadian coaches was conducted to identify the factors associated with three variables: coaches’ attitude towards LTAD, intention to adopt LTAD, and LTAD adoption status. 279 (56%)(35.4 ± 12.1 years) of them knew LTAD and filled out the entire questionnaire. Perceived knowledge of LTAD, its trialability, observability, intention to adopt, coaches’ certification level, and organisational support were the best predictors of LTAD model adoption level in coaching’ practice (R2=0.579, F9,184=28.32, p<0.001). Coaches in late-developing sports declared having greater knowledge of LTAD, more capacity for its implementation, and lower perceived complexity of application.
本研究的目的是记录加拿大体育教练采用长期运动员发展(LTAD)的过程,并确定预测因素:1)他们采用这种社会创新的态度和意图,以及2)他们的LTAD采用水平。运用罗杰斯的创新扩散理论,对499名加拿大教练进行了调查,以确定教练对LTAD的态度、采用LTAD的意向和采用LTAD的状态这三个变量的相关因素。其中279人(56%)(35.4±12.1岁)了解LTAD并填写了完整问卷。LTAD认知知识、可试性、可观察性、采用意向、教练认证水平和组织支持是教练实践中LTAD模型采用水平的最佳预测因子(R2=0.579, f9184 =28.32, p<0.001)。在发展较晚的运动项目中,教练声称他们对LTAD有更多的了解,更有能力实施LTAD,并且感知到的应用复杂性更低。

The purpose of this study was to analyze the relationship among players’ perceptions of authentic leadership, trust in coach, and group cohesion. Male college soccer players responded to questionnaire items about these three factors. A total of 249 survey data were analyzed by structural equation modeling. Authentic leadership had a significant positive relationship with trust in coach and group cohesion; trust in coach had a significant positive relationship with group cohesion; and trust in coach was a mediator in the relationship between authentic leadership and group cohesion. These findings suggest when coaches are authentic leaders, athlete and team outcomes may benefit.
本研究的目的是分析球员对真实领导的认知、对教练的信任和团队凝聚力之间的关系。男大学生足球运动员对这三个因素进行了问卷调查。采用结构方程模型对249份调查数据进行分析。真实型领导与教练信任、团队凝聚力呈显著正相关;教练信任与团队凝聚力呈显著正相关;教练信任在真实性领导与团队凝聚力的关系中起中介作用。这些发现表明,当教练是真正的领导者时,运动员和团队的结果可能会受益。

The purpose of this study was to compare judo-related physical fitness, body composition, and isokinetic knee functions of male judo athletes from different age groups. Subjects for this study were thirty male judo athletes and randomly divided into three groups: cadet judo athletes (CJA, n=10), junior judo athletes (JJA, n=10) and senior judo athletes (SJA, n=10). Body composition, physical fitness, anaerobic wingate test, and isokinetic knee strength test were analyzed for comparing characteristics of judo athletes with age. Statistical analysis was performed using one-way ANOVA followed Scheffe post hoc test. As the result of this study, body weight and muscle mass were significantly higher in the SJA group than those in the CJA group. The SJA group had significantly higher sit-up, vertical jump, side step and sit-and-reach values than the CJA and JJA groups, and the JJA group had significantly higher sit-up and back strength values than the CJA group. The absolute values of peak power (PP) and average power (AP) and relative values of PP in the SJA group showed significant differences compared to the CJA and JJA groups. Therefore, present findings provided research evidence that anaerobic power, maximal muscle strength and endurance would positively regulate performance of judo athletes with increasing age and athletic experience. Coaches and trainers in the field should try to provide a periodic training program to improve judo-related physical fitness and succeed.
摘要本研究的目的是比较不同年龄组男性柔道运动员的柔道相关体能、身体组成和膝关节等运动功能。本研究以30名男性柔道运动员为研究对象,随机分为三组:初级柔道运动员(CJA, n=10)、初级柔道运动员(JJA, n=10)和高级柔道运动员(SJA, n=10)。分析柔道运动员的身体组成、体能、无氧翼门测试和等动膝关节力量测试,比较不同年龄运动员的特点。采用单因素方差分析和Scheffe事后检验进行统计学分析。本研究的结果是,SJA组的体重和肌肉质量明显高于CJA组。SJA组的仰卧起坐、纵跳、侧步和坐伸值显著高于CJA组和JJA组,JJA组的仰卧起坐和背部力量值显著高于CJA组。与CJA和JJA组相比,SJA组的峰值功率(PP)和平均功率(AP)的绝对值和PP的相对值有显著性差异。因此,本研究结果提供了研究证据,无氧功率、最大肌力和耐力会随着年龄和运动经验的增加而正向调节柔道运动员的成绩。在场上的教练和训练员应该尝试提供一个定期的训练计划,以提高柔道相关的身体素质和成功。

A Conceptual Framework for the Internalization of a Sport Object through Sport Video Gaming 通过体育视频游戏内化运动对象的概念框架

As the sport marketplace has become competitive, sport organizations are challenged to attract and maintain sport consumers. Using sport video games as a marketing communication strategy may be a good way to reach young sport consumers due to the popularity of sport video games(SVGs). Based on Kim and Ross’ findings (2006, it is believed that playing SVGs may foster a psychological connection with a sport team. The current study assumes the extent to which motives to play SVGs and a sense of presence contribute to explain a psychological connection with a sports team (i.e., internalization) based on the Fan Attitude Network (FAN) model (Funk & James, 2004). The internalization model of a sport object through sport video gaming is proposed based on the review of literature. The model assumes that motives to play SVGs and a sense of presence contribute to explaining what variables contribute to a sport identity. The purpose of the study is to understand the influence of motives to play SVGs and a sense of presence on a sport identity. A theoretical model depicting the relationship between motives to play SVGs and a sport identity, the relationship between a sense of presence and a sport identity, and the interaction effect between motives and a sense of presence on a sport identity was proposed. Testing the proposed model would contribute to the understanding of what drives sport video gamers to facilitate personal connections with their favorite teams and guide implications for marketing communication practice.
随着体育市场的竞争日益激烈,体育组织面临着吸引和维持体育消费者的挑战。由于体育电子游戏(svg)的流行,使用体育电子游戏作为营销传播策略可能是接触年轻体育消费者的好方法。根据Kim和Ross的发现(2006),人们认为玩svg可以培养与运动队的心理联系。目前的研究基于球迷态度网络(Fan)模型(Funk & James, 2004),假设玩svg的动机和存在感在多大程度上有助于解释与运动队的心理联系(即内化)。在文献综述的基础上,提出了体育游戏对运动对象的内化模型。该模型假设玩svg的动机和存在感有助于解释哪些变量对运动身份有影响。本研究的目的是了解玩社交游戏的动机和存在感对运动身份的影响。在此基础上,提出了游戏动机与运动身份、存在感与运动身份的关系、动机与存在感对运动身份的交互作用的理论模型。测试所提出的模型将有助于理解是什么驱使体育电子游戏玩家促进与他们最喜欢的球队的个人联系,并为营销传播实践提供指导。
