The purpose of the study was to evaluate the frequency and intensity of players' actions associated with jumping in the 3x3 basketball game, to compare these data between men's and women's teams, and to compare the data obtained with existing data from 5- on-5 basketball. Jumps during the five final games of the men's and women's national championship were recorded using the inertial measurement device VERT which was previously calibrated using force platform. The significance level set for the study was p ≤ 0.05. The number and height of jumps during the execution of jump shots from outside and inside the paint, lay -up shots, rebounds, and blocks were monitored. Female and male players performed 1.05 and 1.63 jumps per minute, respectively, in the 3x3 basketball game. For all jumps observed, the number of jumps was higher in males than in females, and the largest differences were found in jump shots inside the paint and jump when blocking (p < 0.05). The relative intensity of the jumps, expressed as a percentage of the maximum countermovement jump obtained before the play, showed that heights of just over 50% of the maximum were most common, except for the male players executing layup shots were the heights reached over 70% of the maximum. Comparing the results with previous studies, we summarize that the performance level of the athletes influences the frequency of actions. Low level teams executed fewer actions than high level teams, in parallel to their physical fitness.
本研究的目的是评估运动员在3x3篮球比赛中与跳跃相关的动作频率和强度,比较男子和女子球队的这些数据,并将获得的数据与现有的5对5篮球数据进行比较。在男子和女子全国锦标赛的最后五场比赛中,使用惯性测量装置VERT记录跳跃,该装置之前使用力平台校准。本研究的显著性水平为p≤0.05。在禁区内外跳投,上篮,篮板和盖帽的执行过程中,跳跃的次数和高度被监控。在3 × 3篮球赛中,男女运动员的跳速分别为每分钟1.05和1.63。在所有的跳跃中,男性的跳跃次数高于女性,在禁区内的跳投和封盖时的跳投中差异最大(p < 0.05)。跳跃的相对强度,以在比赛前获得的最大反向跳跃的百分比表示,表明高度刚刚超过最大值的50%是最常见的,除了执行上篮的男性球员高度超过最大值的70%。通过与以往研究结果的比较,我们总结出运动员的竞技水平对动作频率的影响。低水平的团队比高水平的团队执行的行动更少,这与他们的身体素质是平行的。

Although unstable strength training has gained popularity among athletes and the recreational population, there is scarce data regarding the applicability of this type of exercise program in school settings. The aim of the study was to investigate whether the implementation of an unstable surface strength exercise program in physical education would contribute to the improvement of physical fitness in 14-years students. A sample of 220 adolescents (112 girls) was randomly assigned to either the EXP (calisthenics exercise under unstable conditions) or the CON group (prescribed physical education strength exercise program). Before and after the 12- week period, upper-body isometric and repetitive strength were accessed using 4 motor tests. In addition, skinfold thickness (ST) was determined in subscapular, pectoral, and abdominal areas. Both groups improved strength performance (p < 0.01), with greater increase in EXP compared to CON for all motor tests (p < 0.01, ES = 0.21 – 0.45). Both groups decreased total, subscapular and abdominal ST (p < 0.05), with no significant effect of group. Unstable surface strength exercises are effective in improving physical abilities and should be included in the regular physical education curriculum.
尽管不稳定力量训练在运动员和娱乐人群中越来越受欢迎,但关于这种类型的训练项目在学校环境中的适用性,却缺乏数据。本研究的目的是调查在体育教育中实施不稳定的表面力量锻炼计划是否有助于提高14岁学生的体质。220名青少年(112名女孩)被随机分配到EXP(不稳定条件下的健美操)或CON组(规定的体育力量锻炼计划)。在12周之前和之后,通过4项运动测试来评估上半身等长和重复力量。此外,还测定了肩胛下、胸部和腹部的皮褶厚度(ST)。两组都提高了力量表现(p<0.01),在所有运动测试中,EXP比CON增加更大(p<0.01,ES=0.21-0.45)。两组都降低了总ST、肩胛下ST和腹部ST(p<0.05),但组间无显著影响。不稳定的表面力量练习对提高身体能力是有效的,应该纳入常规体育课程。

Teaching physical education (PE) at a distance has been a major challenge for primary school teachers because younger students are not yet able to use Information Communication Technology (ICT) independently and their concentration is lower. In order to maintain the development of student's motor skills, it was very important to incorporate various PE games into all distance learning lessons. The aim of this study was to investigate whether primary school teachers conduct PE classes at all in the context of distance education and what constraints and challenges they encounter. The sample included 181 primary school teachers. For data collection, we used a questionnaire prepared and used for the analysis of teaching during the first declared epidemic in Slovenia in March 2020. The data were collected between January 15 and February 15, 2021. The results showed that teachers mostly taught the content of hiking, natural forms of movement, dance, and athletics. Dance was taught by more teachers teaching grades 1 to 3 (x2 = 4.731; g = 1; p = 0.030), and Theoretical Content was taught by more teachers teaching grades 4 to 6 (x2 = 19.434; g = 1; p < 0.001). The most common problem in distance education in PE was technological problems and students' lack of knowledge in using ICT. Compared to teachers with fewer years of service, teachers with the most years of service had the most difficulty providing assistive instructional technology (p = 0.001) and knowledge of using digital tools (p = 0.015; p = 0.31).
远程体育教学一直是小学教师面临的一大挑战,因为年龄较小的学生还不能独立使用信息通信技术,他们的注意力也较低。为了保持学生运动技能的发展,将各种体育游戏纳入所有远程学习课程是非常重要的。本研究的目的是调查小学教师是否在远程教育的背景下开设体育课,以及他们遇到的限制和挑战。样本包括181名小学教师。为了收集数据,我们使用了一份问卷,该问卷用于分析2020年3月斯洛文尼亚首次宣布疫情期间的教学情况。这些数据是在2021年1月15日至2月15日期间收集的。结果表明,教师主要教授徒步旅行、自然运动形式、舞蹈和体育运动的内容。1至3年级的教师更多地教授舞蹈(x2=4.731;g=1;p=0.030),4至6年级的教师更多地教授理论内容(x2=19.434;g=1,p<0.001)。体育远程教育中最常见的问题是技术问题和学生缺乏使用信息通信技术的知识。与服务年限较少的教师相比,服务年限最多的教师在提供辅助教学技术(p=0.001)和使用数字工具的知识(p=0.015;p=0.031)方面最困难。

The purpose of this study was to investigate the effects of 8-week aerobic and combined exercise (aerobic and resistance) modalities on body composition and resting metabolic rate (RMR) in sedentary young adults. Twenty-two physically inactive females (20.9 ± 1.6 years) were recruited to participate in the study. They were randomly assigned to three groups: aerobic exercise group (AEG), combined exercise group (CEG), and control group (CG). The training programs were performed three times a week. The body fat percentage was assessed by the bioelectrical impedance method. The RMR was determined via indirect calorimetry. Within-group analysis revealed no significant differences in body mass index and body fat percentage considering the three groups. However, both training groups increased their RMR significantly (AEG: 12.3%, p= 0.017; CEG: 9.7%, p= 0.043). No significant difference was observed in CG for the RMR. Between-group analysis revealed that participating in aerobic training induced slightly better (but insignificant) improvements in all measures compared to combine training. In conclusion, the results of the study highlighted the positive influences of both aerobic and combine training interventions on the RMR in sedentary female young adults compared to controls.
本研究的目的是研究8周有氧运动和联合运动(有氧和阻力)模式对久坐年轻人身体成分和静息代谢率(RMR)的影响。招募了22名身体不活跃的女性(20.9±1.6岁)参与该研究。他们被随机分为三组:有氧运动组(AEG)、联合运动组(CEG)和对照组(CG)。培训项目每周进行三次。通过生物电阻抗法评估体脂百分比。RMR通过间接量热法测定。组内分析显示,考虑到三组,体重指数和体脂百分比没有显著差异。然而,两个训练组的RMR都显著增加(AEG:12.3%,p=0.017;CEG:9.7%,p=0.043)。RMR的CG没有观察到显著差异。组间分析显示,与联合训练相比,参加有氧训练在所有指标上都有稍好(但不显著)的改善。总之,与对照组相比,该研究结果强调了有氧和联合训练干预对久坐女性年轻人RMR的积极影响。

The purpose of the research was to examine the relationship between ranking of success and match analysis parameters, and to develop a regression formula to understand the effectiveness of these parameters on league score in the season of 2018- 2019 Turkish Spor Toto Football Super League. A total of 306 competitions in the league consisting of 18 teams in the season of 2018-2019 were examined. The parameters used in the current research were total, high intensity, and sprint running distances with or without ball, number of successful shots and passes, ball possessions in the first, second and third regions, and points earned at the end of the season. In accordance with the findings, the most related parameters to the league score were total running distance with ball, and the number of successful shots and passes p<0.01) and high intensity running distance with or without ball, sprint running distance, successful passes, and shots were mostly seen in the third region in the season of 2018-2019 Turkish Spor Toto Football Super League. The multivariate linear regression analysis F(7,10)=6.05, p=0.0058 was found statistically significant, and showed that 68 % of the variance in the dependent variable (R2 adjusted=0.68) was explained by the ratio of high intensity running distance with ball to high intensity running distance, sprint distance with ball to sprint distance, and the number successful shots and passes. Future studies may also examine the match location, defensive parameters, opposing teams, and other match analysis parameters.
本研究的目的是检验成功排名与比赛分析参数之间的关系,并建立回归公式来了解这些参数对2018-2019赛季土耳其斯波尔托托足球超级联赛联赛联赛得分的有效性。2018-2019赛季,由18支球队组成的联盟共有306场比赛被审查。目前研究中使用的参数是总的、高强度的、有球或无球的短跑距离、成功的投篮和传球次数、第一、第二和第三区域的控球次数以及赛季末的得分。根据研究结果,与联赛得分最相关的参数是总有球跑动距离,成功射门和传球次数p<0.01),而高强度有球或无球跑动距离、冲刺跑动距离、成功传球和射门大多出现在2018-2019赛季土耳其斯波尔托托足球超级联赛的第三区。多元线性回归分析F(7,10)=6.05,p=0.0058具有统计学意义,并表明因变量(R2调整=0.68)中68%的方差由高强度有球跑动距离与高强度跑动距离、有球冲刺距离与冲刺距离的比率以及成功射门和传球次数来解释。未来的研究还可能检查比赛地点、防守参数、对方球队和其他比赛分析参数。

The literature has revealed that knee injuries are the most common injury among basketball players. The strength ratios dominant/non-dominant and posterior-anterior around the knee joint are used to evaluate strength balances. But there has been far less research published about strength evaluation in professional-level basketball. The objectives of the present study were: (i) to compare hamstring and quadriceps muscles’ strength values during concentric knee extension and flexion at different angular velocities at professional level basketballers, (ii) to determine dominant and non-dominant strength values during these contractions. 13 professional male basketball athletes voluntarily participated in the study. The leg strength was evaluated with an isokinetic dynamometer at 240- 180-120-600 /s angular velocities. The hamstring and quadriceps unilateral peak torque ratio (H/Q) and dominant non-dominant strength ratio were calculated. The independent t-test was computed to bilateral and unilateral strength outputs. There was no statistically significant difference between dominant and non-dominant strength values at peak torque, normalized peak torque, and H/Q at all angular velocities. Relative peak torque outputs in both legs were similar at all angular velocities. Also, the H/Q was calculated as ≥0.60 in all velocities. The results of this study suggest there were not any significant differences in the unilateral and bilateral evaluations of professional basketballers. These nonsignificant differences could be related to the necessity to maintain similar strength of two legs.
文献表明,膝关节损伤是篮球运动员中最常见的损伤。膝关节周围的优势/非优势和前后强度比用于评估强度平衡。但是,关于职业水平篮球力量评估的研究却少得多。本研究的目的是:(i)比较专业水平篮球运动员在不同角速度下同心膝关节伸展和屈曲过程中腘绳肌和股四头肌的力量值,(ii)确定这些收缩过程中的优势和非优势力量值。13名职业男子篮球运动员自愿参与了本研究。用等速测功机在240-180-120-600/s的角速度下评估腿部力量。计算腘绳肌和股四头肌单侧峰值扭矩比(H/Q)和优势-非优势力量比。对双侧和单侧强度输出进行独立t检验。在所有角速度下,峰值扭矩、归一化峰值扭矩和H/Q下的主导强度值和非主导强度值之间没有统计学上的显著差异。在所有角速度下,两条腿的相对峰值扭矩输出相似。此外,所有速度下的H/Q均计算为≥0.60。这项研究的结果表明,对职业篮球运动员的单侧和双侧评价没有任何显著差异。这些不显著的差异可能与保持双腿力量相似的必要性有关。

Although it is known that physical fitness in children has an effect on cognitive functions, the relationship between physical fitness and attention levels is unknown in children who do regular sports. The aim of our study is to investigate the relationship between physical fitness and attention level in children aged 7-12 who do sports and to compare it with children who do not do sports. 55 athletes (25 boys; 30 girls) and 55 non-athletes (26 boys; 29 girls) participated in the study. The average age of the participants was 11.63±0.77, respectively; 11.80±0.67 years. Children participating in the study were divided into 2 groups as athletes and non-athletes. Physical fitness levels of the children were evaluated with the Eurofit Test Battery. Attention levels were determined using the Bourdon Attention Test (BAT). When the two groups were compared in terms of physical fitness parameters and attention levels, significant difference was found in favor of the athlete (p0.05). As a result of our study, it was found that the attention levels were more developed in athlete children with higher physical fitness parameters. Considering that attention deficit has an important place today, we suggest that children with attention deficit should be directed to sports activities and included in attention deficit treatments.
虽然我们知道儿童的身体健康对认知功能有影响,但对于经常运动的儿童,身体健康与注意力水平之间的关系尚不清楚。本研究旨在探讨7-12岁从事体育运动的儿童身体素质与注意力水平的关系,并与不从事体育运动的儿童进行比较。运动员55名(男生25名;30名女孩)和55名非运动员(26名男孩;29名女孩)参加了这项研究。参与者的平均年龄分别为11.63±0.77岁;11.80±0.67年。参与研究的儿童被分为运动员和非运动员两组。采用Eurofit测试电池对儿童的身体健康水平进行评估。注意水平采用波登注意测试(BAT)来确定。两组在体质参数和注意水平上比较,运动员有显著性差异(p0.05)。我们的研究结果发现,运动员儿童的注意水平越高,身体素质参数越高。考虑到注意力缺陷在今天的重要地位,我们建议将注意力缺陷儿童引导到体育活动中,并将其纳入注意力缺陷治疗中。

The fitness center industry is growing year after year and marketing is becoming more challenging. Especially in recent years, when communication is shifting to digital channels. We have reviewed all research resources that have studied the relationships between digital marketing, branding and sales in the fitness industry from 2010 to 2020. Three different databases (Pubmed, Sciencedirect, Ebscohost) and grey literature identified 482 potential articles, of which 28 were relevant. We found researchers strongly recommend fitness centres use digital channels and social networks to communicate with their members. The researchers cited Facebook as a great way to create value for the fitness centre brand and indirectly increase the chances of buying fitness memberships. Instagram has a similar effect, with the fitness industry primarily advising to engage with influencers. Marketing through digital channels and technology innovations greatly contributes to branding and the sales of fitness services, so fitness centres should integrate digital marketing as a key part of marketing activities.
健身中心行业正逐年增长,市场营销也变得越来越具有挑战性。尤其是近年来,当通信正在向数字渠道转移时。我们回顾了2010年至2020年健身行业数字营销、品牌和销售之间关系的所有研究资源。三个不同的数据库(Pubmed、Sciencedirect、Ebscohost)和灰色文献确定了482篇潜在文章,其中28篇是相关的。我们发现,研究人员强烈建议健身中心使用数字渠道和社交网络与会员交流。研究人员认为,脸书是为健身中心品牌创造价值并间接增加购买健身会员资格机会的好方法。Instagram也有类似的效果,健身行业主要建议与有影响力的人接触。通过数字渠道和技术创新进行营销,极大地促进了健身服务的品牌化和销售,因此健身中心应将数字营销作为营销活动的关键部分。

The parallel bar dip is one of the most commonly used calisthenic exercises. However, a recommended elbow angle in terms of activation patterns has not yet been studied. The aim of this study is to examine the activation values of the pectoralis major and triceps muscle groups during parallel bar dip at different elbow angles. Ten male volunteers (age: 25.1 ± 3.9 years) with regular exercise habits participated in the study. During the parallel bar dip, the pectoralis major, lateral triceps and long triceps muscles were examined at elbow angles of 75°, 85° and 95°. The movement was standardized using the metronome (60 beats.min-1) and evaluated in three phases (eccentric = 2 seconds, isometric = 1 seconds, concentric = 2 seconds). There was no statistically significant difference between the angles for pectoralis major (p>0.05). Significant differences were observed in triceps muscle groups, especially in favor of 75° in the isometric phase (p<0.05). The greatest activation in terms of phases was seen in concentric contraction for all muscles. This research has shown that the reduction of the elbow flexion angle has a positive effect on the activation of triceps muscle group. However, since there are some methodological limitations (such as biomechanical markers), it can be said that future research should improve these findings.
双杠跳水是最常用的健美操之一。然而,就激活模式而言,推荐的肘部角度尚未得到研究。本研究的目的是检测在不同肘部角度下,平行杆下倾时胸大肌和三头肌群的激活值。10名有规律运动习惯的男性志愿者(年龄:25.1±3.9岁)参与了这项研究。在双杠跳水过程中,在75°、85°和95°的肘部角度检查胸大肌、三头肌外侧肌和三头肌长肌。使用节拍器(60次/分-1)对动作进行标准化,并分三个阶段进行评估(偏心=2秒,等距=1秒,同心=2秒)。胸大肌的角度之间没有统计学上的显著差异(p>0.05)。在三头肌组中观察到显著差异,尤其是在等长期有利于75°(p<0.05)。所有肌肉的同心收缩在相位方面表现出最大的激活。研究表明,肘关节屈曲角度的减小对三头肌群的激活有积极作用。然而,由于存在一些方法上的局限性(如生物力学标记),可以说未来的研究应该改进这些发现。

The aim of this research was to examine the body height of Montenegrin adults - students of the University of Montenegro of both sexes, and the foot length which was used as an alternative to estimating the body height. The nature and scope of this study was to analyze 713 individuals (370 men, aged 21.78±2.13 and 343 women, aged 21.01±1.57). The protocol of the ISAK was used for anthropometric measurements. Means and standard deviations were obtained. The t-test was used to compare the means of foot lengths and body heights between the sexes. The relationship between body heights and foot lengths was determined by using simple correlation coefficients and their 95% confidence interval. A linear regression analysis was then performed to examine the extent to which foot length can be a reliable predictor body height. The results have shown that Montenegrin males are 183.23±7.16 centimeters tall and have a foot length of 26.85±1.55 centimeters, and Montenegrin females are 168.38±6.78 centimeters tall and have a foot length of 24.13±1.29 centimeters. In accordance with previous studies, it has been confirmed that Montenegrin adults are the second highest nation in Europe, with both sexes. It was also confirmed that foot length reliably predicts body height for both sexes.
这项研究的目的是检查黑山成年人(黑山大学的男女学生)的身高,以及用作估计身高的替代方法的脚长。本研究的性质和范围是分析713人(370名男性,年龄21.78±2.13,343名女性,年龄21.01±1.57)。ISAK方案用于人体测量。获得平均值和标准偏差。t检验用于比较性别之间的脚长和身高的平均值。身高和脚长之间的关系是通过使用简单的相关系数及其95%的置信区间来确定的。然后进行线性回归分析,以检验脚长在多大程度上可以作为可靠的身高预测指标。结果表明,黑山男性身高183.23±7.16厘米,脚长26.85±1.55厘米;黑山女性身高168.38±6.78厘米,脚长24.13±1.29厘米。根据之前的研究,已经证实黑山成年人是欧洲第二高的国家,男女都有。研究还证实,脚的长度可以可靠地预测两性的身高。
