Abstract Introduction. Lipid profile is one of the main determinants of cardiovascular health status. Moderate and vigorous physical activity can positively influence lipid profile, and one such activity is sport climbing. The main aim of this study was to determine the lipid profile and to investigate the influence of training experience on the lipid profile of youth climbers. Material and Methods. This research included 12 youth climbers aged 15.33 ± 1.30 years (6 males, 6 females), who were tested on anthropo-metric indices and lipid profile (total cholesterol, high-density lipoproteins, low-density lipoproteins, triglycerides) using the point-of-care testing. Variables of lipid profile were correlated with years of climbing experience by Spearman’s rank correlation coefficients, while the differences between females and males were checked by the Mann-Whitney U test. Results. Youth climbers had acceptable levels of all measured lipid parameters. Training experience was significantly positively correlated with body mass index (R = 0.76, p < 0.01) and significantly negatively correlated with cholesterol (R = -0.80, p < 0.01). Conclusions. Results support that climbing as a vigorous and enjoyable physical activity might be advertised as a proxy for reaching recommended amounts of physical activity among adolescents, which is associated with improved lipid profile. However, this is only a preliminary investigation advocating that determinants of health status related to climbing practice should be further investigated.
摘要 简介。血脂状况是心血管健康状况的主要决定因素之一。适度和剧烈的体育锻炼可对血脂状况产生积极影响,攀岩运动就是其中之一。本研究的主要目的是测定青少年攀岩运动员的血脂状况,并研究训练经验对血脂状况的影响。材料和方法。本研究包括 12 名年龄为 15.33 ± 1.30 岁(6 男 6 女)的青少年攀岩运动员,他们接受了人体测量指数和血脂概况(总胆固醇、高密度脂蛋白、低密度脂蛋白、甘油三酯)的定点检测。通过斯皮尔曼秩相关系数检验血脂指标变量与登山年限的相关性,通过曼-惠特尼U检验检验男女之间的差异。结果显示青少年攀岩运动员的所有测量血脂参数都达到了可接受的水平。训练经验与体重指数呈明显正相关(R = 0.76,p < 0.01),与胆固醇呈明显负相关(R = -0.80,p < 0.01)。结论研究结果表明,攀岩作为一种剧烈而愉快的体育活动,可以作为青少年达到建议运动量的替代品进行宣传,这与血脂状况的改善有关。不过,这只是一项初步调查,我们主张进一步研究与攀岩运动相关的健康状况决定因素。

Abstract Introduction. The article aims to analyse the current state of knowledge about mountaineering in the Himalayas through a systematic literature review. Material and Methods. For this purpose, the following research questions were formulated: Which journals publish the most studies concerning the Himalayas and which authors make significant contributors to this area of research? What are the dominant research themes, and how have they changed over the years? What factors contribute to success and deaths in Himalayan mountaineering? The study is based on a mapping review of publications from the Scopus, Web of Science, EBSCO and Google Scholar databases with research profiling and co-word analysis using VOSviewer. In total, 189 articles selected for review were subjected to automatic content analysis (text mining, clustering) in the VOSviewer program to produce a self-organising map of keywords, grouped into four thematic areas: (1) tourism management, geo-ecology and local community; (2) psychology, anthropology and risk of high altitude physical activity; (3) acclimatisation, hypoxia pathophysiology; and (4) altitude and acute disease, brain and pulmonary oedema. Results. In the qualitative phase of the analysis, success and failure factors in Himalayan mountaineering were identified. It can be concluded that it is becoming safer and more common for climbers to reach the summit and such achievements are more accessible to women and older people. Conclusions. Safety increases can be attributed to the obligatory use of oxygen by mountain guides, better infrastructure on the trail (two-way system of lifelines), more reliable weather forecasts, and the assistance of experienced leaders.
摘要 导言。本文旨在通过系统的文献综述,分析喜马拉雅山登山运动的知识现状。材料与方法。为此,我们提出了以下研究问题:哪些期刊发表的有关喜马拉雅山的研究最多,哪些作者对这一研究领域做出了重要贡献?主要的研究主题是什么,这些主题多年来发生了哪些变化?哪些因素导致喜马拉雅登山的成功和死亡?本研究基于对 Scopus、Web of Science、EBSCO 和 Google Scholar 数据库中的出版物进行的图谱审查,以及使用 VOSviewer 进行的研究剖析和共词分析。VOSviewer 程序对总共 189 篇被选中进行审查的文章进行了自动内容分析(文本挖掘、聚类),以生成一个关键词自组织地图,并将其分为四个主题领域:(1) 旅游管理、地理生态学和当地社区;(2) 心理学、人类学和高海拔体育活动的风险;(3) 适应性、缺氧病理生理学;以及 (4) 高海拔与急性疾病、脑和肺水肿。研究结果。在定性分析阶段,确定了喜马拉雅登山的成功和失败因素。可以得出的结论是,登山者登顶喜马拉雅山变得越来越安全和普遍,妇女和老年人也更容易取得这样的成就。结论。安全系数的提高可归因于登山向导必须使用氧气、登山道上有更好的基础设施(双向生命线系统)、更可靠的天气预报以及经验丰富的领队的协助。

Abstract Introduction. Low physical activity, transition to retirement and unfavorable socio-economic changes may significantly reduce the quality of life of older people. The increasing average life expectancy of the population requires measures intended to promote physical activity among the elderly in order to improve their quality of life. The aim of the research was to determine the relationship between exercise intensity and the quality of life in U3A students over 60 years of age. Material and methods. A diagnostic survey was applied in the research. The following research tools were used: WHOQOL-BREF Questionnaire to assess the quality of life, Minnesota Questionnaire (MLTPAQ) to test the intensity level of physical activity, and the authors’ own questionnaire. The study involved 673 individuals over 60 years of age from the Kuyavian-Pomeranian Region in Poland. Results. People who took low-intensity exercise more often were more satisfied with life and health. Likewise, they had higher quality of life assessments in the physical, psychological and environmental context in comparison with those who were not sporty. Individuals who went in for moderate physical effort more often assessed their quality of life better in the social area. Respondents who engaged in intense physical activities valued the quality of life in physical, psychological and environmental domains higher. Conclusions. The positive influence of regular exercise on the quality of life requires further promotion of this activity, health education, and extension, diversification and adjustment of the offer of sports activities to the needs and capabilities of the elderly.
摘要 导言。体力活动少、向退休过渡以及不利的社会经济变化可能会大大降低老年人的生活质量。随着人口平均预期寿命的延长,需要采取措施促进老年人的体育锻炼,以提高他们的生活质量。本研究旨在确定 60 岁以上 U3A 学生的运动强度与生活质量之间的关系。材料和方法研究采用了诊断性调查。使用了以下研究工具WHOQOL-BREF 问卷用于评估生活质量,明尼苏达问卷(MLTPAQ)用于测试体育锻炼的强度水平,以及作者自己的问卷。研究涉及波兰库亚维安-波美拉尼亚地区的 673 名 60 岁以上老人。结果显示经常进行低强度运动的人对生活和健康更加满意。同样,与不爱运动的人相比,他们在身体、心理和环境方面的生活质量评估也更高。更经常参加中等强度体育锻炼的受访者在社交方面对生活质量的评价更高。参加激烈体育活动的受访者对身体、心理和环境方面的生活质量评价更高。结论经常锻炼对生活质量有积极影响,因此需要进一步推广这项活动,开展健康教育,并根据老年人的需求和能力扩大体育活动的范围,使其多样化,并对其进行调整。

Abstract Introduction. The purpose of this study was to evaluate the effects of bouldering on upper and lower limb muscle strength and body balance. Material and Methods. The study group consisted of 22 climbers (aged 27.23 ± 4.81) with at least 2 years of bouldering experience, while the control group consisted of 20 men (aged 23.10 ± 5.28) not practicing rock climbing. The study received approval from the local bioethical commission in Poland. Static and dynamic stabilographic parameters were measured with eyes open (EO) and closed (EC) on the Biodex Balance System SD USA (BBS) platform. Subsequently, the maximum muscle torques of the elbow, hip, knee and ankle joints were measured in isometric conditions. Hand-grip strength (HGS) with and without the thumb was assessed using a handheld dynamometer. Results. Climbers achieved significantly higher values of HGS with the thumb of both hands (p < 0.005), foot extensors strength (FES) in both limbs (p < 0.05) and left hip extensors (HES L) (p < 0.05). They also achieved significantly lower values of all stabilographic parameters, indicating better balance compared to the control group (p < 0.05). An interaction of HES x SIDE across the groups was observed (F(1,40) = 13.588, p < 0.001 η2 = 0.254). Moreover, there was a statistically significant negative correlation of ankle extensors strength with medial-lateral stability index (MLSI EC) (right: r = -0.418; left: r = -0.331) and fall risk index (FRI6-2) (right: r = -0.520; left: r = -0.435). Conclusions. Regular climbing training develops muscle strength, especially FES, HES, HGS, and improves balance. Climbing can be used for prevention of muscle weakness and equilibrium disorders.
摘要 简介。本研究旨在评估抱石运动对上下肢肌肉力量和身体平衡的影响。材料和方法。研究组由 22 名至少有两年攀岩经验的攀岩者(年龄为 27.23 ± 4.81)组成,对照组由 20 名没有攀岩经验的男性(年龄为 23.10 ± 5.28)组成。该研究获得了波兰当地生物伦理委员会的批准。在美国 Biodex 平衡系统 SD(BBS)平台上,分别在睁眼(EO)和闭眼(EC)状态下测量静态和动态稳定参数。随后,在等长条件下测量了肘关节、髋关节、膝关节和踝关节的最大肌肉扭矩。使用手持式测力计对有拇指和无拇指的手握力(HGS)进行评估。结果显示登山者的双手拇指握力(HGS)(p < 0.005)、双脚伸肌力量(FES)(p < 0.05)和左侧髋关节伸肌力量(HES L)(p < 0.05)均明显高于其他登山者。与对照组相比,他们的所有稳定参数值也明显降低,这表明他们的平衡能力更强(p < 0.05)。在各组中观察到 HES x SIDE 的交互作用(F(1,40) = 13.588,p < 0.001 η2 = 0.254)。此外,踝关节外展肌力量与内外侧稳定性指数(MLSI EC)(右侧:r = -0.418;左侧:r = -0.331)和跌倒风险指数(FRI6-2)(右侧:r = -0.520;左侧:r = -0.435)存在统计学意义上的显著负相关。结论定期进行攀岩训练可增强肌肉力量,尤其是FES、HES和HGS,并改善平衡能力。攀岩可用于预防肌肉无力和平衡失调。

Abstract Introduction. The purpose of this randomized, double-blind, placebo-controlled study was to evaluate the effect of ashwagandha supplementation on the body composition, blood health and recovery indices, as well as the safety of ashwagandha supplementation in wrestling. Material and Methods. To investigate this, body composition (using dual energy X-ray absorptiometry; DEXA) and blood parameters as indicators of athletes’ health status (i.e., hematology, liver, kidney and muscle tissue function, lipid profile) were measured before and after 8-week supplementation with ashwagandha extract (600 mg/day) in professional national team wrestlers following an intensive training plan (as part of an annual training cycle). Results. At the end of the study, there was a significant increase in fat-free mass and muscle mass, with a significant decrease in fat mass (both in absolute and relative terms) in both ashwagandha and placebo groups (main effect of time, p < 0.05). However, ashwagandha supplementation did not affect any of the body composition parameters (main effect of group or interaction of time and group, p > 0.05). Moreover, intense wrestling training induced an increase in blood creatine kinase activity as an indicator of muscle tissue damage (main effect of time, p < 0.05). Ashwagandha supplementation did not significantly affect any hematological or biochemical blood parameters (p > 0.05 for main effect of group and interaction of time and group). However, the increase in creatine kinase activity during the study seemed to be more pronounced in the placebo group (post-hoc; p < 0.05) than in the ashwagandha group (post-hoc; p > 0.05). Conclusions. In conclusion, ashwagandha supplementation at 600 mg daily for 8 weeks is well tolerated and safe for professional wrestlers. This strategy does not appear to offer additional body composition benefits beyond the effect of intense wrestling training. On the other hand, our results indicate some potential for ashwagandha in improving muscle tissue recovery, which needs to be confirmed on a larger population of athletes.
摘要 简介。这项随机、双盲、安慰剂对照研究旨在评估补充灰树花对摔跤运动员身体成分、血液健康和恢复指数的影响,以及补充灰树花的安全性。材料和方法为了研究这个问题,在专业国家摔跤队运动员按照强化训练计划(年度训练周期的一部分)补充灰树叶提取物(600 毫克/天)8 周前后,测量了他们的身体成分(使用双能 X 射线吸收测定法;DEXA)和作为运动员健康状况指标的血液参数(即血液学、肝脏、肾脏和肌肉组织功能、血脂概况)。结果显示研究结束时,灰树花组和安慰剂组的无脂质量和肌肉质量均有显著增加,脂肪质量(绝对值和相对值)均有显著减少(时间的主效应,P < 0.05)。然而,补充灰树花不会影响任何身体成分参数(组别的主效应或时间与组别的交互效应,P > 0.05)。此外,高强度摔跤训练导致血液肌酸激酶活性增加,而肌酸激酶活性是肌肉组织损伤的指标(时间的主效应,P < 0.05)。补充芦根对血液和生化指标没有明显影响(组别的主要影响以及时间和组别的交互影响,P > 0.05)。不过,在研究过程中,安慰剂组肌酸激酶活性的增加似乎比灰树花组更明显(事后比较;p < 0.05)(事后比较;p > 0.05)。结论总之,职业摔跤运动员在连续 8 周每天服用 600 毫克的灰树花补充剂后,其耐受性和安全性都很好。除了高强度摔跤训练的效果外,这一策略似乎不会对身体成分产生额外的益处。另一方面,我们的研究结果表明,灰树花在改善肌肉组织恢复方面具有一定的潜力,这需要在更多的运动员身上得到证实。

Abstract Introduction. Patellar instability in younger patients is a common injury (3.3% of all knee injury episodes) and the most frequent dislocation of the knee observed. The sensitivity and reliability of clinical diagnostic tests after medial patellofemoral ligament (MPFL) reconstruction remain unclear and biased. The primary aim of the present study was thus to detect, using wavelet analysis, differences in the rearfoot loading of the operated limb of patients after MPFL reconstruction. The authors hypothesised that applying this specific examination technique would allow for more accurate and less biased clinical results evaluation. Material and Methods. The study involved a group of 15 female subjects (age: 22.8 ± 6.3 years; weight: 58.5 ± 5.1 kg) after MPFL reconstruction and a control group of 29 healthy females (23.2 ± 2.8 years; 61.1 ± 7.7 kg). The subjects performed a 30-second classic Romberg test on a treadmill (Noraxon FDN-T) equipped with a matrix of baroresistive sensors to measure ground reaction forces. Time-frequency analysis of the signal originating from the treadmill was done using an analytic Morse wavelet. Results. The results indicate differences in visual control and vestibular stability in patients before and 3 months after a surgery. They are characterised by a deficit of energy attributed to visual control in favour of an excess of energy associated with vestibular control. Patellar instability patients show greater energy expenditure to maintain body balance for at least 6 months after MPFL reconstruction. Conclusions. Patellar instability patients have increased vestibular control while maintaining balance. Our results suggest an extended rehabilitation period for patients after MPFL reconstruction beyond 6 months.
摘要 简介。年轻患者的髌骨不稳是一种常见损伤(占膝关节损伤总数的 3.3%),也是最常见的膝关节脱位。髌股关节内侧韧带(MPFL)重建后的临床诊断测试的灵敏度和可靠性仍不明确且存在偏差。因此,本研究的主要目的是利用小波分析检测 MPFL 重建术后患者手术肢体后足负荷的差异。作者假设,应用这种特殊的检查技术可以更准确地评估临床结果,减少偏差。材料和方法。研究涉及一组 15 名接受 MPFL 重建术的女性受试者(年龄:22.8 ± 6.3 岁;体重:58.5 ± 5.1 千克)和一组 29 名健康女性受试者(年龄:23.2 ± 2.8 岁;体重:61.1 ± 7.7 千克)。受试者在装有气压传感器矩阵的跑步机(Noraxon FDN-T)上进行了 30 秒经典朗伯格测试,以测量地面反作用力。使用解析莫尔斯小波对来自跑步机的信号进行了时频分析。结果显示结果表明,手术前和手术后 3 个月的患者在视觉控制和前庭稳定性方面存在差异。其特点是视觉控制能量消耗不足,而前庭控制能量消耗过多。髌骨不稳的患者在 MPFL 重建后至少 6 个月内维持身体平衡的能量消耗更大。结论。髌骨不稳患者在保持平衡的同时,前庭控制能力也有所增强。我们的研究结果表明,MPFL 重建术后患者的康复期应延长至 6 个月以上。

Patellar instability in younger patients is a common injury (3.3% of all knee injury episodes) and the most frequent dislocation of the knee observed. The sensitivity and reliability of clinical diagnostic tests after medial patellofemoral ligament (MPFL) reconstruction remain unclear and biased. The primary aim of the present study was thus to detect, using wavelet analysis, differences in the rearfoot loading of the operated limb of patients after MPFL reconstruction. The authors hypothesised that applying this specific examination technique would allow for more accurate and less biased clinical results evaluation. Material and Methods. The study involved a group of 15 female subjects (age: 22.8 ± 6.3 years; weight: 58.5 ± 5.1 kg) after MPFL reconstruction and a control group of 29 healthy females (23.2 ± 2.8 years; 61.1 ± 7.7 kg).

Time-frequency analysis of the signal originating from the treadmill was done using an analytic Morse wavelet. Results. The results indicate differences in visual control and vestibular stability in patients before and 3 months after a surgery. They are characterised by a deficit of energy attributed to visual control in favour of an excess of energy associated with vestibular control. Patellar instability patients show greater energy expenditure to maintain body balance for at least 6 months after MPFL reconstruction. Conclusions.

ABSTRACTWatching sport events at tourist destinations is an appealing attraction for tourists because it generates excitement and direct understanding of the event, as well as the destination. Thus, a good event image can motivate people to re-attend sport events, make priority choices among similar games and even attach their personal feelings to the events. However, few researchers have explored the factors affecting sport event images and its consequential effects, particularly in the post-pandemic era. In the current study, 417 valid questionnaires were collected by convenience sampling during the 68th Macao Grand Prix, and analysed by structural modelling, via SPSS23 and AMOS26. The results showed that travel motivation, tourist-resident interaction and event quality are all important factors that positively influence the event image, with event quality having the most significant effect. Subsequently, event images positively affect event attachment and loyalty. Considering that the continued coronavirus disease 2019 pandemic travel risk still exist, it was incorporated as a moderator, which revealed that it negatively moderated the relations between event images, attachment and loyalty. This study supplements theoretical defects in sport event tourism by enriching the causes and effects of event images, and provides practical suggestions for sport event policymakers, planners and tourism managers.KEYWORDS: Sport event tourismevent imagetourist-resident interactionevent quality Disclosure statementNo potential conflict of interest was reported by the author(s)
在旅游目的地观看体育赛事对游客来说是一种很有吸引力的吸引,因为它能让游客兴奋,让他们对赛事和目的地产生直接的了解。因此,一个好的赛事形象可以激励人们重新参加体育赛事,在同类赛事中做出优先选择,甚至将个人情感与赛事联系起来。然而,很少有研究人员探索影响体育赛事图像及其后果的因素,特别是在大流行后时代。本研究在第68届澳门大奖赛期间,采用方便抽样的方法收集了417份有效问卷,并通过SPSS23和AMOS26进行结构建模分析。结果表明,旅游动机、游客与居民互动和事件质量都是正向影响事件形象的重要因素,其中事件质量的影响最为显著。随后,事件形象正向影响事件依恋和忠诚。考虑到2019冠状病毒病大流行的持续旅行风险仍然存在,将其纳入调节因子,结果表明,它对事件图像、依恋和忠诚之间的关系具有负向调节作用。本研究通过丰富赛事形象的成因和效果,补充了体育赛事旅游的理论缺陷,为体育赛事政策制定者、策划者和旅游管理者提供了实践建议。关键词:体育赛事旅游形象游客与居民互动赛事质量披露声明作者未发现潜在利益冲突

ABSTRACTHiking has become an increasingly popular activity for all age groups and can be seen as one of the major nature-based tourist activities. As in other areas of tourism, a trend toward a growing emphasis on quality is identifiable in hiking tourism. To better address the needs and demands of hiking tourists, knowledge of motives for hiking is crucial. Focusing on the context of hiking tourism, the aim of this study is to examine the motives of hikers and to identify possible underlying individual differences in motives. By using an adapted questionnaire based on the existing inventory ‘Bernese motive and goal inventory in leisure and health sports’ (BMZI), hiking tourists at three different locations in the Black Forest in Germany were interviewed. A total of 113 questionnaires were used for statistical analysis. First, an exploratory factor analysis (EFA) was applied to classify motives for engaging in hiking, resulting in five motives: ‘experience of nature’, ‘health’, ‘distraction’, ‘social contact in sport’, ‘physique’, and ‘competition’. Second, further analyses revealed significant differences in terms of gender, age, educational level, frequency of exercising, frequency of hiking, and type of vacation regarding single motives for hiking, with the motive ‘health’ showing most differences according to sociodemographic and behavioral characteristics (i.e. gender, frequency of exercising, frequency of hiking). The results of this study provide a better understanding of hiking tourists and their motives. Furthermore, the results are useful for organizations, marketing, destinations, and networks in the field of sport and tourism to promote hiking tourism.KEYWORDS: Active tourismmotivationoutdoor activityrecreational activity AcknowledgmentsThe authors would like to thank all participants contributing to the study.

Editorial Gatekeeping in Sports News During Prime Time Television in a Public Broadcaster 公共广播电视黄金时段体育新闻的编辑把关
Q3 Health Professions Pub Date : 2023-09-01 DOI: 10.2478/pjst-2023-0013
Carla Cruz, Duarte Araújo
Abstract Introduction. Based on Shoemaker's model of gatekeeping, this study addresses two questions: What social representations of sports are promoted by the prime time news program of the public television broadcaster Radio Televisão Portuguesa (RTP)? How do editors assess sports news stories during the editorial decision-making process? Material and Methods. For this, we quantitatively examined all the sports content in the prime time ‘Telejornal’ daily news program of RTP during a trimester. Moreover, we studied the factors that influenced editorial decisions, by conducting naturalistic participant observation and semi-structured interviews. Results. Results indicate that facts of greater public protagonism, which cause a significant emotional reaction and are relatable to the public, are more newsworthy. The main constraints influencing the editorial decisions were organized in three co-dependent areas: Social System (macro level), RTP Organization (meso level) and Telejornal Newsroom (micro level). Conclusions. Findings contribute to a reduction in social stereotypes created by television broadcasters, and to sports actors optimizing their communication strategy.
摘要介绍。基于Shoemaker的看门人模型,本研究解决了两个问题:公共电视广播公司葡萄牙广播电台(RTP)的黄金时段新闻节目促进了体育的哪些社会表征?在编辑决策过程中,编辑如何评估体育新闻报道?材料和方法。为此,我们定量研究了RTP电视台黄金时段每日新闻节目中三个月的所有体育内容。此外,我们通过进行自然参与观察和半结构化访谈,研究了影响编辑决策的因素。结果。结果表明,更大的公众主角的事实,引起显著的情绪反应和与公众相关,更有新闻价值。影响编辑决策的主要制约因素可归纳为三个相互依存的领域:社会系统(宏观层面)、RTP组织(中观层面)和电视期刊编辑室(微观层面)。结论。研究结果有助于减少电视广播公司造成的社会刻板印象,并有助于体育演员优化他们的传播策略。

Abstract Introduction. This study aimed to investigate the effects of a six-week complex contrast training (CCT) intervention on the athletic performance of highly-trained amateur male soccer players during the pre-season period. Material and Methods. Participants aged 21.3 were randomized to CCT (n = 7) or active (i.e. standard soccer training) control (CG; n = 9) groups. Athletic performance was assessed using the 30 m linear sprint test time, standing long jump distance (SLJ), countermovement jump (CMJ) height, and unilateral right-left knee flexion and extension isokinetic maximal strength tests. The experimental group replaced part of the standard soccer training schedule with three CCT sessions per week for six weeks. A two (pre-post intervention) by two (CCT, CG) mixed ANOVA was used to analyze the exercise-specific effects. In addition, between-group comparisons at post-test were conducted with baseline scores as covariate. Within group changes were analyzed using paired t-test. Results. Significant group-by-time interaction effects were found for all dependent variables (p < 0.001 – 0.004). Post-hoc tests using paired t-test revealed significant improvements in all dependent variables in CCT (all p ≤ 0.001; effect size (g) = 0.29 – 0.96; %Δ = 4.5 – 14.7), but not in CG (p = 0.174 – 0.633; g = 0.03 – 0.20; %Δ = 0.4 – 2.6). Further, Bonferroni adjusted post-hoc analysis using baseline scores as a covariate showed post-test differences in favor of CCT compared to CG for all variables. Conclusions. CCT is recommended as an effective training strategy during the pre-season to improve athletic performance among highly-trained amateur male soccer players.
摘要介绍。本研究旨在探讨为期六周的复杂对比训练(CCT)干预对训练有素的业余男子足球运动员季前运动表现的影响。材料和方法。年龄21.3岁的参与者被随机分配到CCT (n = 7)或积极(即标准足球训练)对照组(CG;N = 9)组。采用30米直线冲刺测试时间、立定跳远距离(SLJ)、反动作跳跃(CMJ)高度和单侧左右膝关节屈伸等速最大力量测试对运动成绩进行评价。实验组将部分标准足球训练计划改为每周三次CCT,持续六周。采用双(干预前后)双(CCT, CG)混合方差分析分析运动特异性效果。此外,以基线分数作为协变量进行后测组间比较。组内变化采用配对t检验分析。结果。所有因变量均存在显著的群体-时间交互效应(p <0.001 - 0.004)。采用配对t检验的事后检验显示,CCT的所有因变量均有显著改善(均p≤0.001;效应量(g) = 0.29 - 0.96;%Δ = 4.5 - 14.7),但CG没有(p = 0.174 - 0.633;G = 0.03 ~ 0.20;%Δ = 0.4 - 2.6)。此外,Bonferroni调整了使用基线分数作为协变量的事后分析,结果显示,与CG相比,所有变量的后测试差异都有利于CCT。结论。CCT被推荐为赛季前有效的训练策略,以提高训练有素的业余男子足球运动员的运动表现。
