We aimed to evaluate the effect of joint distraction exercises with elastic band as a warm-up method versus an only standard warm-up on lower-body maximal strength performance in male bodybuilders and to determine possible moderator variables affecting performance. In the study, seventeen male bodybuilders who met the inclusion criteria were evaluated. The bodybuilders performed two sets of four joint distraction exercises with 30 seconds of rest following the standardized warm-up versus the standardized warm-up only. The maximal strength performance of bodybuilders was measured with an interval of 96 hours. Joint distraction exercises with the elastic band following the standardized warm-up moderately increased lower-body maximal strength performance of the bodybuilders (p = 0.00; Cohen’d = 0.45, 95%CI = 0.30-0.60). In addition, age (p = 0.34, β = 0.03), height (p = 0.92, β = 0.00), body weight (p = 0.61, β = 0.00), training experience (p = 0.66, β = -0.02) and body mass index (p = 0.55, β = 0.01) were not moderator variables for this training method. Our study showed that joint distraction exercises with elastic bands could acutely improve lower-body maximal strength performance in male bodybuilders regardless of anthropometric characteristics. Practitioners and coaches may prefer this training method before strength training to increase the strength performance of their athletes.
我们的目的是评估用弹性带作为热身方法的关节分散练习与唯一标准热身对男性健美运动员下体最大力量表现的影响,并确定影响表现的可能的调节变量。在这项研究中,17名符合纳入标准的男性健美运动员接受了评估。在标准化热身和标准化热身之后,健美运动员进行了两组四组关节分散练习,休息30秒。健美运动员的最大力量表现以96小时为间隔进行测量。标准化热身后进行松紧带关节分散训练,适度提高健美运动员下体最大力量表现(p = 0.00;Cohen’d = 0.45, 95%CI = 0.30-0.60)。此外,年龄(p = 0.34, β = 0.03)、身高(p = 0.92, β = 0.00)、体重(p = 0.61, β = 0.00)、训练经验(p = 0.66, β = -0.02)和体重指数(p = 0.55, β = 0.01)不是该训练方法的调节变量。我们的研究表明,无论人体测量特征如何,使用松紧带进行关节分散训练都能显著提高男性健美运动员的下半身最大力量表现。在力量训练之前,练习者和教练可能更喜欢这种训练方法,以提高运动员的力量表现。

This study aimed to: (i) present normative data of the variables related to the start in the four swim strokes by tier and sex, and; (ii) understand the relationship between the 15th meter mark time and the final race time of the male and female swimmers competing in the four 50 m events at the 2021 European Championships. Participants were all male and female swimmers who competed in the 50 m events at the 2021 LEN European Championships held in Budapest. The official race times and block times were retrieved from the official competition website. All starting variables were analyzed in a dedicated software for race analysis. The 15th meter mark time was used as the start main outcome. For all events by sex, the 15th meter mark time was the variable presenting the highest and largest tier effect (p < 0.001) besides the final race time. Overall, despite the swim stroke, the variables related to the underwater phase were also responsible for the significant tier effect (p < 0.001). The 15th meter mark time presented a high to very-high relationship with the final race time in all four swim strokes. This relationship was stronger in freestyle (both sexes). That is, swimmers who achieve the 15th meter mark sooner are more likely to deliver better performances. Coaches must be aware that the underwater phase plays a key-role on the swimmers’ (both sexes) start performance. Nonetheless, different strategies can be used based on the swimmers’ strength and weaknesses. Moreover, the start performance in all four swim strokes and in both sexes can strongly predict the final race time.
本研究的目的是:(1)提供四种泳姿中不同等级和性别的起跑相关变量的规范性数据;(ii)了解2021年欧洲锦标赛4个50米项目中男女游泳运动员的15米标志时间与最后比赛时间之间的关系。参与者都是参加在布达佩斯举行的2021年LEN欧洲锦标赛50米项目的男女游泳运动员。官方比赛时间和街区时间从官方比赛网站检索。所有的起跑变量都在专用的比赛分析软件中进行了分析。15米计时作为起跑的主要成绩。在按性别划分的所有项目中,除最后的比赛时间外,15米标志时间是表现出最高和最大分层效应的变量(p < 0.001)。总的来说,除了游泳姿势,与水下阶段相关的变量也对显著的分层效应负责(p < 0.001)。在所有四种泳姿中,15米的时间与最后的比赛时间呈高到非常高的关系。这种关系在自由泳中更为明显(无论男女)。也就是说,更快到达15米大关的游泳运动员更有可能取得更好的成绩。教练必须意识到水下阶段对游泳运动员(男女)的起跑表现起着关键作用。然而,根据游泳者的优势和劣势,可以使用不同的策略。此外,所有四种泳姿的起跑成绩以及男女选手的起跑成绩都能很好地预测最终的比赛成绩。

The present study explored visual strategies employed by female soccer players of high, medium, and low levels of expertise. We used eye-tracking technology to examine how skill-based differences related to gaze behavior in 30 participants (10 in each group) who were required to respond physically to film images projected on a screen using soccer skills (penalty kick, dribbling, pass reception, and defensive cover). Data were collected from search rate (visual fixations duration and number, and number of fixated areas), percentage of viewing time, and variability of pupil diameter. Analyses revealed that female elite players engaged in more visual fixations, directed gaze toward more relevant areas of the scene, and showed less variability of pupil diameter, compared to their non-elite counterparts. Our findings seem to corroborate prior research which compared participants with different levels of expertise while performing soccer skills.
本研究探讨了高、中、低水平女子足球运动员的视觉策略。我们使用眼球追踪技术来研究30名参与者(每组10人)的技能差异与凝视行为的关系,这些参与者被要求对使用足球技术(点球、盘带、接球和防守掩护)投射在屏幕上的电影图像做出身体反应。数据收集自搜索率(注视时间和次数、注视区域数量)、注视时间百分比和瞳孔直径变异性。分析显示,与非精英选手相比,女性精英选手更多地专注于视觉,将目光引向场景中更相关的区域,瞳孔直径的变化也更小。我们的发现似乎证实了先前的研究,该研究比较了不同专业水平的参与者在表演足球技巧时的表现。

Anaerobic performance is considered an indicator of performance for short-term muscle activities of high intensity. It is important to determine whether different anaerobic field tests performed to measure anaerobic performance can be used as an alternative to WAnT performed in the laboratory. The study aimed to compare the anaerobic performance with laboratory and field tests in trained children. One-hundred four athletes between the ages of 10 and 16, minimum age of training of one year in different sports voluntarily participated in the study. Wingate Anaerobic Test (WAnT) was performed as the reference test. Besides, Running-based Anaerobic Sprint Test (RAST) and Pediatric RAST (PRAST) were performed to determine anaerobic performance. Peak power (PP), average power (AP), minimum power (MP), fatigue index (FI) and total exercise time (TED) were determined for each test. All variables of WAnT, RAST, and PRAST were significantly different (p<0.01). According to test-retest results of all tests, ICC [95% CI] values have a high-reliability coefficient for all variables. It was found there is a high correlation significantly between WAnT and RAST for all variables (p<0.01). Besides, there were also high correlations significantly between WAnT-PRAST and RAST-PRAST excluding fatigue index (p<0.01). As a result of this study, it was determined all tests have high reliability. Considering that WAnT requires complex, expensive device and tools, trained staff and is performed in the form of cycling in the laboratory, RAST and PRAST performed with body weight in field conditions can be used to determine anaerobic performance in trained children. High correlations between tests support this determination.
无氧表现被认为是短期高强度肌肉活动表现的指标。重要的是要确定为测量厌氧性能而进行的不同厌氧现场试验是否可以作为在实验室进行的WAnT的替代方法。该研究旨在将训练有素的儿童的无氧性能与实验室和现场测试进行比较。104名年龄在10 - 16岁之间,最低训练年龄为一年的不同运动项目的运动员自愿参加了研究。Wingate厌氧试验(WAnT)作为参考试验。此外,通过跑步无氧冲刺测试(RAST)和儿科无氧冲刺测试(PRAST)来确定无氧性能。测定各试验的峰值功率(PP)、平均功率(AP)、最小功率(MP)、疲劳指数(FI)和总运动时间(TED)。WAnT、RAST、PRAST各变量差异均有统计学意义(p<0.01)。根据所有检验的重测结果,ICC [95% CI]值对所有变量都具有较高的信度系数。各变量的WAnT与RAST呈极显著的高度相关(p<0.01)。除疲劳指数外,WAnT-PRAST与RAST-PRAST之间也存在显著的高相关性(p<0.01)。本研究结果表明,所有测试均具有较高的信度。考虑到WAnT需要复杂、昂贵的设备和工具,训练有素的工作人员,并且在实验室以循环的形式进行,RAST和PRAST在野外条件下与体重一起进行,可以用来确定训练有素的儿童的厌氧表现。测试之间的高度相关性支持这一判断。

Traditionally, basketball research has used game-related statistics in order to discriminate winning and losing teams. Unfortunately, most investigations refer exclusively to the analysis of men's competitions. In this sense, Tokyo 2020 Olympic Games created a unique opportunity to make gender performance comparison feasible, since it provided same period and environmental conditions for both genders. The aim of this study was to identify which game-related statistics best discriminated winning and losing teams in men and women’s team playing Tokyo 2020 Basketball Olympic Tournament. All statistical data for the 26 games of each gender were obtained from the FIBA website. The MANOVA and discriminant analysis models were run to check differences according to gender and game outcome. The main results revealed 2-point field-goals percentage, defensive rebounds, assists, points in the paint, and effective field goal percentage as key variables to succeed in men and women’s games. However, there were gender discrepancies on 2-point field-goals made, points from turnovers, turnover per ball possession rate (relevant only when discriminating men’s winning teams), and fastbreak points, offensive rebounds percentage, and free-throw rate (only for women’s winning teams). Winning and losing discriminant statistics were quite similar for both, men and women’s teams when only considering traditional box-score stats, but not when analyzing advanced stats.
传统上,篮球研究使用与比赛相关的统计数据来区分输赢球队。不幸的是,大多数调查只涉及对男子比赛的分析。从这个意义上说,2020年东京奥运会为两性提供了相同的时期和环境条件,创造了一个独特的机会,使性别成绩比较成为可能。本研究的目的是确定哪些与比赛相关的统计数据最能区分2020年东京篮球奥运会男女队的输赢球队。26场男女比赛的所有统计数据均来自国际篮联网站。运用方差分析(MANOVA)和判别分析(discriminant)模型检验不同性别和博弈结果的差异。主要结果显示,两分投篮命中率、防守篮板、助攻、禁区得分和有效投篮命中率是男女比赛中成功的关键变量。然而,在两分命中率、失误得分、控球失误率(仅在男队获胜时相关)、快攻得分、进攻篮板率和罚球率(仅在女队获胜时相关)方面存在性别差异。当只考虑传统的统计数据时,男性和女性球队的赢球和输球的歧视性统计数据非常相似,但在分析高级统计数据时则不同。

Low back pain (LBP) prevalence in children and adolescents is high during their lives. School-based interventions have reported effectiveness on back health. The study aimed to determine the effect of an educational back-health intervention on knowledge, postural habits and trunk muscle endurance regarding low back pain prevention for a group of 12 to 13-year-old students using a 6-month follow-up. A non-randomized experimental design. Three groups of 1st-grade secondary school students were selected. A control group (CG), and two experimental groups (EG1 and EG2) who participated in a back-health educational program (BHEP); only one of the experimental groups was given a follow-up learning contract (EG2). Assessments were performed at three different time points: before the intervention (baseline), after (post-test) and 6 months after (follow-up). The level of general knowledge of the experimental groups improved after the intervention. The level of postural habits improved in EG1 and EG2 compared to the CG after the follow-up period (p < .001 in both). An improvement in the level of endurance of the trunk musculature after the intervention was observed only for boys between EG2 and the CG (p < .05). A lower percentage of problems in the lumbar area in EG2 was observed after the 6-month follow-up. Teaching students to take care of their spines seems to have positive effects concerning knowledge, postural habits, and back health
儿童和青少年腰痛(LBP)的患病率在他们的生活中很高。据报告,以学校为基础的干预措施对背部健康有效。本研究旨在通过为期6个月的随访,确定教育背部健康干预对12至13岁学生预防腰痛的知识、姿势习惯和躯干肌肉耐力的影响。非随机实验设计。选取了三组一年级中学生。对照组(CG)和两个实验组(EG1和EG2)参加背部健康教育计划(BHEP);只有一个实验组获得了后续学习合同(EG2)。在三个不同的时间点进行评估:干预前(基线),之后(测试后)和6个月后(随访)。实验组的一般知识水平在干预后有所提高。随访后,EG1和EG2的姿势习惯水平较CG有所改善(p < 0.001)。干预后躯干肌肉耐力水平的改善仅在EG2和CG之间的男孩中观察到(p < 0.05)。在6个月的随访后,观察到EG2腰椎区出现问题的百分比较低。教学生照顾他们的脊椎似乎对知识、姿势习惯和背部健康有积极的影响

Chronic Kidney Patients (CKP) present a negative clinical status, with structural and functional changes in the musculoskeletal system and mental health partly due to a sedentary lifestyle. An effective physical stimulus for CKP is as important as to be able to follow it in the long-term. This study aimed to analyzethe association between some of the most influencing exercise adherence factors in CKP performing an exercise prescription programme. 67 subjects (23.9% women) participated in 14-week exercise programme in 3 dialysis centersin Madrid (Spain).

The aim of the present systematic review was to investigate the determinants of fitness center service quality that most influence customer satisfaction. Studies were identified from searches in PubMed, Scopus, Web of Science and EBSCO databases from 2017 through 2022. The search process was carried out by four independent researchers. Titles and abstracts were reviewed to determine whether the studies met the inclusion criteria. The quality of the reporting of the measures was assessed using a tailored list. The electronic search strategy produced 378 studies. A total of 17 articles met the inclusion criteria. Results of the review support the importance of service quality to improve customer satisfaction, leading to customers future intentions with the brand, increasing loyalty and customer retention. Therefore, positive perceptions of service quality influence customer satisfaction, in turn customer loyalty and retention, and are indispensable for the sustainability of these companies. Through the studies included in this systematic review it was possible to identify nine dimensions of service quality as predictors of customer satisfaction: facility quality, instructors and reception staff quality, price, supporting services, service recovery, service assurance, online marketing, and customer relations. This article provides useful and global information on the most current service quality factors. Given the fitness market's competitiveness, understanding the factors that influence service quality allows managers to better choose their strategies for increasing customer satisfaction.

Physical activity is an important therapeutic strategy in reducing the severity of Covid-19 disease. There is a lack of studies evaluating the level of physical activity among doctors who are the frontline responders of Covid-19 pandemic. The online survey aimed at evaluating the effect factors associated with physical activity levels of doctors during Covid-19 pandemic using International Physical Activity Questionnaire Short Form (IPAQ- SF). The survey included doctors from government and private health sectors of India. Snowballing technique was used to conduct the survey. About 266 Indian doctors with a median age of 36 (IQR = 31, 46) years responded to the anonymous survey consisting of demographic details and IPAQ- SF. Median MET-minutes/week and Inter Quartile Range (IQR) were used to describe the physical activity levels of the doctors. All the data analysis was done in STATA 12.1. The total median MET-duration of doctors was 834 (IQR = 495, 1620) MET-minutes/week with 988 (IQR = 564.3, 2067.9) Kcal/week of total energy expenditure. Low, moderate and high physical activity levels of doctors were 21.4%, 54.5% and 24.1% respectively. Age, gender, doing Covid-19 duties and regular involvement in physical activity before the pandemic have significantly affected PA levels. More than 55% of doctors who reported high or moderate physical activity before the pandemic were doing significantly low physical activity during the pandemic (p < 0.0001). The Covid-19 pandemic has significantly affected the physical activity level in doctors. Doctors aged 31- 40 years performing Covid-19 duties during the conduct of the survey were likely to perform low physical activity. However, those doctors who regularly engaged in physical activity before the pandemic despite the restrictions were found to engage significantly in higher total MET-duration and expended higher energy.
身体活动是降低Covid-19疾病严重程度的重要治疗策略。目前缺乏评估Covid-19大流行一线应对者医生身体活动水平的研究。该在线调查旨在利用国际身体活动问卷简表(IPAQ- SF)评估Covid-19大流行期间医生身体活动水平的相关影响因素。调查对象包括印度政府和私营卫生部门的医生。采用滚雪球法进行调查。约266名年龄中位数为36岁(IQR = 31,46)岁的印度医生接受了由人口统计细节和IPAQ- SF组成的匿名调查。使用met分钟/周中位数和四分位差(IQR)来描述医生的身体活动水平。所有数据分析均在STATA 12.1中完成。医生总met持续时间中位数为834 (IQR = 495,1620) met分钟/周,总能量消耗为988 (IQR = 564.3, 2067.9) Kcal/周。低、中、高运动水平的医生分别占21.4%、54.5%和24.1%。年龄、性别、履行Covid-19职责以及在大流行前经常参加体育活动对PA水平有显著影响。在大流行前报告高强度或中度身体活动的医生中,55%以上在大流行期间的身体活动明显较低(p < 0.0001)。新冠肺炎疫情对医生的身体活动水平产生了重大影响。在进行调查期间,年龄在31- 40岁之间执行Covid-19职责的医生可能会进行较低的体力活动。然而,尽管受到限制,但那些在大流行之前经常从事体育活动的医生,其met总持续时间和消耗的能量都明显更高。
