Match running performance (RP) of Union of European Football Associations Champions League (UCL) and Fédération Internationale De Football Association World Cup (WC) players are often investigated separately; however, no study to simultaneously observed RP in both competitions. Therefore, the main objective of this study was to provide a comparative analysis of RP of professional soccer match-play across two highest-level soccer competitions: UCL and WC. The RPs (UCL; n=244, WC; n=581) of professional soccer players were analyzed using optical systems, and classified according to their playing positions as: central defenders (CD), fullbacks (FB), central midfielders (CM), wide midfielders (WM) and forward (FW). The RP variables included total distance and high intensity running (>5.5 m/s). One-way analysis of variance was used to examine position-specific differences between RP in WC and UCL, while Cohen’s d was used to identify effect sizes. Results indicated that CDs, FBs, CMs, and WMs from UCL covered significantly greater total distance than their counterparts from WC (all moderate effect sizes). In addition, CDs from UCL achieved greater amount of high intensity running than CDs from WC (small effect size). This study demonstrated differences in various aspects of physical performance between two highest-level soccer competitions with variations dependent upon playing position. The findings enabled a more thorough understanding of the physical requirements for playing in UCL and WC, and may have direct consequences for specific training programs.
欧洲足球协会联盟冠军联赛(UCL)和国际足联世界杯(WC)球员的比赛跑动表现(RP)经常被分开调查;然而，没有研究同时观察两场比赛的RP。因此，本研究的主要目的是比较分析两个最高水平的足球比赛:UCL和WC的职业足球比赛的RP。RPs (UCL;WC n = 244;采用光学系统对n=581名职业足球运动员的数据进行分析，并将其按踢球位置分为:中卫(CD)、边后卫(FB)、中前卫(CM)、边锋(WM)和前锋(FW)。RP变量包括总距离和高强度跑步(>5.5 m/s)。单向方差分析用于检验WC和UCL中RP之间的位置特异性差异，而Cohen 's d用于确定效应大小。结果表明，来自UCL的cd、FBs、CMs和WMs覆盖的总距离显著大于来自WC的对应物(均为中等效应值)。此外，来自UCL的cd比来自WC的cd获得了更多的高强度运行量(小效应大小)。本研究表明，在两项最高水平的足球比赛中，身体表现的各个方面存在差异，这种差异取决于比赛位置。研究结果使我们能够更全面地了解参加伦敦联赛和世界杯赛的身体要求，并可能对具体的训练计划产生直接影响。

The Covid-19 pandemic has brought significant changes to the lives of athletes, particularly regarding the uncertainty surrounding the continuation of sports training and the postponement of sporting events. Given these disruptions to athletes’ routines, the role of motivation in sports participation is considered even more crucial. Therefore, this study aimed to examine the differences in motivation for sports participation during the Covid-19 pandemic between senior and junior professional football players. The sample consisted of 358 elite football players from the Premier League of Bosnia and Herzegovina. The players were divided into two groups: senior (n=193, 24.87±3.78 years) and junior (n=165, 18.08±1.00 years) football players. The Participation Motivation Questionnaire (PMQ) was utilized, comprising 19 items classified into six motivational dimensions: “Sports success”, “Social status”, “Friendship”, “Physical health”, “Sports activity”, and “Support”. A five-point Likert scale was used in the questionnaire, which was administered electronically via Google Forms. Results revealed that junior football players achieved significantly higher values in only three out of the 19 items: “Want to be popular” (.005), “Want to get status” (.001), and “Wished for friendly games” (.000). However, there were no differences between the senior and junior football player groups in the remaining 16 items. Also, both groups displayed exceptionally high motivation levels in the dimensions of “Sports success”, “Physical health”, and “’Friendship”, while the weakest results were observed in the dimension of ‘Support’ for both groups. Despite the specific challenges posed by the Covid-19 pandemic, the motivation to play football remains very high among both senior and junior football players. This study is essential as it provides insights into football players’ motivation and identifies differences in motivation levels between junior and senior players. The findings can be valuable for practical purposes, aiming to enhance motivation among football players, especially during circumstances where training conditions are disrupted, such as the Covid-19 pandemic.

Low back pain (LBP) is the most common musculoskeletal complaint. LBP affects all age groups, including college students. In the digital and communication era, computers and gadgets are ordinary. Excessive computer/gadget use can produce musculoskeletal work imbalance leading to LBP. Several risk factors are also linked to LBP, such as flexibility, strength muscle, body mass index (BMI), and standing posture. Thus, our study aims to investigate the association between LBP, screen time, and risk factors in male college students. This study was cross-sectional, involving 132 students. Height and weight were measured, and BMI was obtained. LBP was assessed using the Nordic Musculoskeletal Questionnaire (NMQ), and the duration of computer use was obtained using a questionnaire. Back muscle flexibility was measured using a modified sit and reach test; back muscle strength was measured using Back-Leg Dynamometer. Posture was assessed using the New York Posture Rating Chart (NYPRC). All variables were categorized into two groups. Fifty participants (37.9%) had LBP. Forty-six participants (34.8%) use computer/gadget excessively. The screen time was associated with LBP (p=0.04, OR 2.19, 95%CI 1.05-4.56). No relationship was found between flexibility, back muscle strength, BMI, and posture. Screen time is associated with LBP in male colleges. Excessive screen time had a 2.19 times greater risk of having LBP. This study conclude that excessive screen time is associated with LBP in male college students.
腰痛(LBP)是最常见的肌肉骨骼疾病。腰痛影响所有年龄组，包括大学生。在数字和通信时代，电脑和小工具很普通。过度使用电脑/电子设备会导致肌肉骨骼工作不平衡，从而导致腰痛。一些风险因素也与腰痛有关，如柔韧性、肌肉力量、身体质量指数(BMI)和站立姿势。因此，本研究旨在探讨男性大学生腰痛、屏幕时间和危险因素之间的关系。这项研究是横断面的，涉及132名学生。测量身高和体重，获得BMI。使用北欧肌肉骨骼问卷(NMQ)评估LBP，使用电脑的持续时间使用问卷。背部肌肉柔韧性采用改良的坐姿和伸展测试来测量;背部肌肉力量用后腿测力仪测量。使用纽约姿势评分表(NYPRC)评估姿势。所有变量被分为两组。50名参与者(37.9%)患有LBP。46名受访者(34.8%)过度使用电脑/电子产品。屏幕时间与LBP相关(p=0.04, OR 2.19, 95%CI 1.05-4.56)。没有发现柔韧性、背部肌肉力量、身体质量指数和姿势之间的关系。在男大学生中，屏幕时间与LBP有关。屏幕时间过长则患腰痛的风险高出2.19倍。本研究的结论是:屏幕时间过长与男大学生腰痛有关。

Flexibility is an important determinant of dynamic balance, but studies rarely examined the chronic effects of flexibility training on changes in balance capacity. This study aimed to determine the influence of different forms of flexibility exercises on dynamic balance in female professional football players. Participants were 30 female professional football players (age =19.0±4.1 years), divided into three groups dynamic stretching group (DSG; N=10, age =18.9±3.3 years), static stretching group (SSG; N=10, age =19.5±4.3 years) and control group (N=10, age =18.5±3.3 years). All groups participated in equal football training, while DSG and SSG performed additional flexibility training 3-times a week (10-15 min of duration) throughout the study course (16 weeks). Dynamic balance was measured by the Y-balance test (YBT), and ANOVA for repeated measurement was applied to identify the effects. Results evidenced the significant influence of both flexibility programs on dynamic balance. Both DSG and SSG were equally effective in the first part of the study (until the 8th week), but between the 8th and 16th study week, only DSG improved their balance capacity significantly. Static stretching should be applied in the first phases of flexibility training aiming at the improvement of dynamic balance, but in later phases, usage of dynamic stretching is suggested.

Chronic low back pain (CLBP) is one of the most common musculoskeletal disorders worldwide with far-reaching implications for social, economic, and public health. The study aimed to compare the effect of combined physiotherapy treatment in patients with CLBP. This observational retrospective randomized controlled study involved reviewing medical records of patients who were treated during a period of 6 weeks in the physiotherapy department of the Special Hospital for General Rehabilitation “Banja e Kllokotit,” Kllokot, Republic of Kosovo. The observational research was conducted for 60 patients, divided into two groups: Group 1: experimental group (n=30), with mean age of 41.7 years, average height of 1.68 cm, and average body mass index (BMI) of 71.7 for both sexes; Group 2: control group (n=30) with mean age of 43.1 years, average height of 1.66 cm, and average body mass index (BMI) of 71.5 for both sexes. In Group 1, combined treatment with passive therapy [thermotherapy and transcutaneous electrical nerve stimulation (TENS)], physical exercises, lumbar traction, and walking program was applied, while in Group 2, passive therapy like thermotherapy and TENS was applied. Outcome measurements included pain intensity, lumbar flexibility, revised Oswestry disability index (ODI), and self-confidence, which were assessed pre-treatment, at 3 weeks, and after 6 weeks of clinical treatment. The results showed significant improvement in both groups. However, the improvement was greater and with a significant difference only after 6 weeks in Group 1 compared to Group 2. The differences were observed in various outcome measures, including the visual analog scale for pain (VAS; p<0.0001), fingertip-to-floor distance (FTF; p<0.0001), ODI (p<0.0001), and Rosenberg self-esteem scale (RSE; p=0.0002). According to our data, combined treatment with thermotherapy, therapeutic exercises, lumbar traction, TENS, and walking program was more effective and can be considered as a treatment protocol for patients with CLBP. However, further research is recommended on the efficacy of combined physiotherapy treatment, especially lumbar traction for longer periods.
慢性腰痛(CLBP)是世界范围内最常见的肌肉骨骼疾病之一，对社会、经济和公共卫生具有深远的影响。该研究旨在比较联合物理疗法治疗CLBP患者的效果。这项观察性回顾性随机对照研究回顾了在科索沃共和国Kllokot“Banja e Kllokotit”普通康复专科医院理疗科接受6周治疗的患者的医疗记录。观察性研究60例患者，分为两组:第一组:实验组(n=30)，平均年龄41.7岁，平均身高1.68 cm，男女平均体重指数(BMI) 71.7;第二组:对照组(n=30)，平均年龄43.1岁，平均身高1.66 cm，男女平均体重指数(BMI) 71.5。第1组采用被动治疗[热疗+经皮神经电刺激(TENS)]、体育锻炼、腰椎牵引、步行方案联合治疗，第2组采用热疗+ TENS等被动治疗。结果测量包括疼痛强度、腰椎柔韧性、修订后的Oswestry残疾指数(ODI)和自信心，分别在治疗前、3周和6周临床治疗后进行评估。结果显示两组患者均有显著改善。然而，与第二组相比，第一组的改善更大，仅在6周后就有显著差异。在各种结果测量中观察到差异，包括视觉模拟疼痛量表(VAS);p<0.0001)，指尖到地板的距离(FTF;p<0.0001)， ODI (p<0.0001)， Rosenberg自尊量表(RSE;p = 0.0002)。根据我们的数据，结合热疗、治疗性运动、腰椎牵引、TENS和步行计划的联合治疗更有效，可以考虑作为CLBP患者的治疗方案。然而，建议进一步研究联合物理治疗的疗效，特别是长时间的腰椎牵引。

Judo is often referred to as an explosive sport, which requires great anaerobic strength and capacity, with a well-developed aerobic system. Attaining a high level of physical fitness, strength, and fatigue tolerance is essential for achieving success in competition. Fatigue leads to decreased muscle strength, prolonged reaction time, reduced agility, neuromuscular coordination, overall body speed, concentration, and agility. The intensity at which this phenomenon occurs is known as the lactate threshold. The primary objective of the planned research was to establish a link between maximal oxygen consumption (VO2max), lactate metabolism, and the situational efficiency of selected young judoists. The sample consisted of 30 cadet and junior judo athletes from the national teams of Serbia (average age of 16.43±0.76 years, body height of 176.94±5.15 cm, and body weight of 69.71±10.64 kg). The research employed precisely standardized protocols and modern equipment to determine anthropometric characteristics, and the values of maximal oxygen consumption, lactate thresholds, and the index of a specific judo fitness test among the selected young judo athletes. Based on the obtained results, there was a moderate negative correlation between VO2max and the index of the special judo fitness test, as well as a low correlation between the first lactate threshold (PLAP) and the second lactate threshold (DLAP) with the index of the special judo fitness test (ISJFT). Additionally, a moderate negative correlation was found between VO2max and anthropometric parameters, while PLAP and DLAP exhibited low correlations with anthropometric parameters. The research results quantitatively illustrate the physiological adaptation of the top young judo athletes to the physical demands encountered during years of specific training. The proposed battery of tests can be utilized to assess the functional status of competitors more accurately and determine the competition profile for elite judo athletes.

Climbing performance is considered multifactorial and is characterized by the interaction of technical, tactical, physical, as well as psychological components. However only few studies have investigated these components in elite climbers. The present study aimed to identify elite athletes’ technical and tactical behavior regarding the following parameters: a) type of climbing handhold, b) type of climbing foothold and c) torso motion through video analysis. The sample consisted of the final competitions of IFSC Climbing World Cup Kranj (2019). In total, 543 actions were recorded through SportScout video-analysis program, taking into account the parameters a) type of climbing handhold, b) type of climbing foothold and c) torso motion. According to the results, and concerning handholds, it was observed that the majority of the participants selected to use Incuts / Mini-jugs, regardless of whether they performed the next movement with the left or the right hand. Concerning the footholds, it was found that participants mostly selected to use Big footholds regardless of whether they performed the next movement with the left or the right leg. Finally, regarding the correlation between Torso motion and Handholds and the correlation between Torso motion and Footholds, it was found that the majority of the climbers selected to perform movements without Torso twisting. Only the techniques of stepping with the right foot had a significant effect on the motion of the torso (Chi-Square=15.53, p<0.05).In conclusion, the selection of smaller and more difficult handholds and big footholds, as well as the climber’s trunk maintenance towards the wall are highly important performance elements in elite climbers.

However only few studies have investigated these components in elite climbers. The present study aimed to identify elite athletes’ technical and tactical behavior regarding the following parameters: a) type of climbing handhold, b) type of climbing foothold and c) torso motion through video analysis. The sample consisted of the final competitions of IFSC Climbing World Cup Kranj (2019). In total, 543 actions were recorded through SportScout video-analysis program, taking into account the parameters a) type of climbing handhold, b) type of climbing foothold and c) torso motion. According to the results, and concerning handholds, it was observed that the majority of the participants selected to use Incuts / Mini-jugs, regardless of whether they performed the next movement with the left or the right hand. Concerning the footholds, it was found that participants mostly selected to use Big footholds regardless of whether they performed the next movement with the left or the right leg. Finally, regarding the correlation between Torso motion and Handholds and the correlation between Torso motion and Footholds, it was found that the majority of the climbers selected to perform movements without Torso twisting. Only the techniques of stepping with the right foot had a significant effect on the motion of the torso (Chi-Square=15.53, p<0.05).In conclusion, the selection of smaller and more difficult handholds and big footholds, as well as the climber’s trunk maintenance towards the wall are highly important performance elements in elite climbers.","PeriodicalId":22150,"journal":{"name":"Sport Mont","volume":"51 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79707241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Currently, Chronic Obstructive Pulmonary Disease (COPD) is perceived not only as a pulmonary disease, but more as a systemic disease affecting the functioning of other organs including the locomotor system. The application of physical therapy in patients with COPD has been found to be safe and beneficial. Neuromuscular Electrical Stimulation (NMES) treatment is particularly beneficial for patients who are unable or unwilling to participate in daily activities or regular physical exercise. The efficacy of this technique has not yet been fully demonstrated in patients with COPD. Therefore, this study aimed to evaluate the effects of NMES on peripheral muscle strength and exercise tolerance in COPD patients. As part of the literature review for this study, seven studies over the last 19 years have been taken into consideration. The review included the following databases: Physiotherapy Evidence Database (PEDro), Google Scholar, and PubMed. Based on our literature review, we concluded that NMES has positive effects on increasing peripheral muscle strength and exercise tolerance in COPD patients. Future research should examine whether the therapeutic effects are long-lasting, whether they are experienced by all COPD patient groups, and which frequency or type of NMES delivers the most effective results.

The goal of this research is to evaluate and compare the functional abilities of the special anti-terrorist unit from Serbia and professional basketball players. The idea is to determine whether members of the special unit police have high functional abilities and at what level are they compared to professional athletes. The sample of participants, for the purposes of this research, consisted of 162 respondents with an average age of 29.75±8.12 years who were classified into two groups. One group consisted of members of the SAF (special anti-terrorist force) (n=101) of average age 33.74±6.19 years and in other group were elite level professional basketball players from Serbia (n=57), of average age 22.39±4.25 from three Serbian clubs. To measure cardiorespiratory fitness, a cardiopulmonary exercises test (CPET) was performed on a treadmill (HPCOSMOS ®). Maximal oxygen consumption (VO2max), as a measure of aerobic capacity, was determined using the Quark CPET system (Cosmed®) by direct monitoring of gas exchange (oxygen and carbon dioxide). Aerobic ability of members of the Serbian SAF (special anti-teroristic force) can be considered excellent and almost close to the professional athletes, but statisticly lower (p<0.05). Anaerobic capacity is also high and there is no difference in relation to basketball players (p>0.05). These results can be explained by the selection of people who are chosen for this unit, which can be called very rigorous and equated with sports selection. The results of our study point to the fact that a high level of cardiorespiratory fitness is not only required by professional sports, but also by certain professions such as SAF.

CrossFit is recognized as one of the fastest growing modes of high-intensity functional training. This strength and conditioning program is used to optimize physical competence in ten fitness domains: (1) cardiovascular/ respiratory endurance, (2) stamina, (3) strength, (4) flexibility, (5) power, (6) speed, (7) coordination, (8) agility, (9) balance, and (10) accuracy. The aim of this review is to provide an overview related to Crossfit and its implication in aerobic and anaerobic parameters. Specifically, in this work, we will discuss the impact that this type of physical activity can have on a physiological level. Furthermore, the tools will be provided to understand how, by modulating the intensity, one can have benefits at an aerobic and anaerobic level. We will also review studies using CF as a resistance training methodology and finally discuss the findings of the various studies and provide recommendations for future studies.
