Wet-cupping therapy (WCT) is one of the oldest known medical techniques, used as a traditional and complementary therapy with a wide application all around the world for general health. Research on the effects of WCT on sports performance are sparse and inconsistent. Thus, we aimed to explore the effects of WCT on repeated sprint ability, wellness, and exertion in young active males. Forty-nine active adult males (age: [28 ​± ​5] years; body height [177 ​± ​8] cm; body mass: [79 ​± ​7] kg; body mass index: [25.4 ​± ​1.8] kg/m2) were selected for the study. The participants performed a running-based sprint test on two separate occasions (Control and Post-WCT). WCT was performed 24 ​h before the testing session. They completed the Hooper questionnaire to assess their well-being (i.e., sleep, stress, fatigue, and soreness) before each session. The rating of perceived exertion (RPE) was collected after each testing session. A higher maximum power (p ​< ​0.05, effect size [ES] ​= ​0.6), mean power (p ​< ​0.01, ES ​= ​0.5) and minimum power (p ​< ​0.01, ES ​= ​0.6) were recorded post-WCT as compared to Control session along with a better perceived sleep (p ​< ​0.01, ES ​= ​0.85). Perceived stress (p ​< ​0.01, ES ​= ​0.6) and RPE (p ​< ​0.001; ES ​= ​1.1) were lower during the post-WCT compared to the Control session. The present findings demonstrated that WCT moderately enhanced repeated sprint ability and had positive effects on perceived sleep, stress, and exertion. WCT may be an effective ergogenic aid to improve repeated sprint ability and general well-being in young adult males. Future large-scale multicentric clinical studies are paramount to confirm the results of our study.

拔罐疗法(Wet-cupping therapy,WCT)是已知的最古老的医疗技术之一,是一种传统的辅助疗法,在世界各地广泛应用于普通健康领域。有关湿拔罐疗法对运动表现的影响的研究很少,而且不一致。因此,我们的目的是探索 WCT 对年轻运动男性的重复冲刺能力、健康和体力消耗的影响。79 ± 7] 千克;体重指数:[25.4 ± 1.8]:[25.4 ± 1.8] kg/m2)。参与者分别在两个场合(对照组和WCT后)进行了跑步短跑测试。WCT 在测试前 24 小时进行。每次测试前,他们都要填写胡珀问卷,以评估自己的健康状况(即睡眠、压力、疲劳和酸痛)。每次测试后都会收集体力感知评分(RPE)。与对照组相比,WCT 测试后的最大功率(p < 0.05,效应大小 [ES] = 0.6)、平均功率(p < 0.01,效应大小 [ES] = 0.5)和最小功率(p < 0.01,效应大小 [ES] = 0.6)均有所提高,同时睡眠质量也有所改善(p < 0.01,效应大小 [ES] = 0.85)。与对照组相比,WCT 后的感知压力(p < 0.01, ES = 0.6)和 RPE(p < 0.001; ES = 1.1)更低。本研究结果表明,WCT 可适度提高重复冲刺能力,并对感知睡眠、压力和体力消耗产生积极影响。WCT可能是一种有效的运动辅助工具,可提高年轻男性的重复冲刺能力和整体健康水平。未来的大规模多中心临床研究对证实我们的研究结果至关重要。

Assessment of clinical depression metrics in cardiac patients using the patient health Questionnaire-9 before and after phase-II cardiac rehabilitation 在第二阶段心脏康复前后使用患者健康问卷-9 评估心脏病患者的临床抑郁指标
IF 2.3 Q2 SPORT SCIENCES Pub Date : 2023-09-11 DOI: 10.1016/j.smhs.2023.09.004

Cardiovascular disease remains a leading cause of morbidity and mortality, a fact that is commonly associated with co-morbidities such as clinical depression. While phase II cardiac rehabilitation is an established intervention for those with cardiovascular disease, its effect on patients who also suffer from depression are under studied. Aim: To quantify Pre- and Post-cardiac rehabilitation questionnaire scores collected from a large patient data registry. For this investigation, 27 ​670 patients completed Patient Health Questionnaire-9 questionnaires both Pre- and Post-rehabilitation (averaging [28.0 ​± ​8.7] phase II sessions). Findings reveal that questionnaire scores decreased by 40%–48% across all groups, a finding that was independent of assigned sex, race, and ethnicity. Moreover, when data were stratified for questionnaire scores that may indicate major and minor depressive disorder, phase II cardiac rehabilitation outcomes were lower by 61% and 49% respectively. While all groups exhibited lower questionnaire scores following cardiac rehabilitation participation, numerical differences at Pre- and Post-rehabilitation time points indicate that males and White patients have more favorable scores. This latter observation, while not confirmed currently, appears to be linked to referral rates to phase II cardiac rehabilitation, which remain poor for females, racial and ethnic minorities.

心血管疾病仍然是发病率和死亡率的主要原因,这通常与临床抑郁症等并发症有关。虽然第二阶段心脏康复是针对心血管疾病患者的一种既定干预措施,但其对同时患有抑郁症的患者的影响还未得到充分研究。目的:量化从一个大型患者数据登记处收集到的心脏康复前和康复后的问卷得分。在这项调查中,27 670 名患者在康复前和康复后(平均[28.0 ± 8.7]次第二阶段疗程)填写了患者健康问卷-9 问卷。研究结果显示,所有组别的问卷得分都下降了 40%-48%,这一结果与性别、种族和民族无关。此外,如果对可能显示重度和轻度抑郁障碍的问卷分数进行分层,则第二阶段心脏康复的结果分别降低了 61% 和 49%。虽然所有组别在参与心脏康复后的问卷得分都较低,但康复前和康复后时间点的数字差异表明,男性和白人患者的得分更高。后一项观察结果目前尚未得到证实,但似乎与第二阶段心脏康复的转诊率有关,女性、少数种族和少数民族的转诊率仍然较低。

Self-modeling (SM) and self-control (SC) feedback can be presented as two solutions for learning improvement. Therefore, the aim of the present study was to investigate the effects of SM and SC feedback on 100-m freestyle performance of professional swimmers and waterpolo players. 25 elite male swimmers and waterpolo players, were randomly assigned to four groups: swimmer group with SM, swimmer group with SM and SC feedback, waterpolo players group with SM, and waterpolo players group with SM and SC feedback. 100-m freestyle times and performance were recorded. SM and SC feedback for the participants were utilized at the acquisition stage. The device used included a Lenovo B570 laptop and an Exilim ZR200 canon camcorder. SM and SC feedback presented to the swimmers and waterpolo players led to improved speed and results, and the effect of presenting SM with SC feedback to swimmers had better results. In conclusion, the present study indicates that SC modeling of watching video is a suitable method for professional swimmers. Water polo trainers can also use SM and SC feedback to enhance their players' swimming technique.

自我建模(SM)和自我控制(SC)反馈可作为学习改进的两种解决方案。因此,本研究旨在探讨自我模拟和自我控制反馈对专业游泳运动员和水球运动员 100 米自由泳成绩的影响。25 名精英男子游泳运动员和水球运动员被随机分配到四组:游泳运动员组(SM)、游泳运动员组(SM 和 SC 反馈)、水球运动员组(SM)和水球运动员组(SM 和 SC 反馈)。记录 100 米自由泳的时间和成绩。在获取阶段,为参与者提供了 SM 和 SC 反馈。使用的设备包括联想 B570 笔记本电脑和 Exilim ZR200 佳能摄像机。向游泳运动员和水球运动员提供的 SM 和 SC 反馈提高了速度和成绩,向游泳运动员提供 SM 和 SC 反馈的效果更好。总之,本研究表明,观看视频的 SC 建模是一种适合专业游泳运动员的方法。水球教练也可以利用 SM 和 SC 反馈来提高运动员的游泳技术。

Individual executive function improvement through physical and cognitive training is a research hotspot in physical education and cognitive science. However, few studies have evaluated whether combined physical and cognitive training (CPCT) has greater benefits for executive function performance and cerebral oxygenation in adolescent athletes than cognitive training alone. This study randomly assigned 33 adolescent shooting athletes to a CPCT (n ​= ​17) or computerized cognitive training (CCT, n ​= ​16) group and compared their executive function after six weeks of training. All subjects were assessed using the 2-back, task-switching, and Stroop tests before and after training. The prefrontal cortex oxygenated hemoglobin (Oxy-Hb) activation level was monitored while executing the three tasks using functional near-infrared spectroscopy. Our results showed that the CPCT and CCT groups similarly improved their updating function as indicated by the 2-back task accuracy. The CPCT group significantly improved the switching function in the task-switching test accuracy, while the CCT group did not. However, both groups did not improve in behavioral performance as indicated by the inhibition function in the Stroop task. Cerebral oxygenation, indicated by the oxy-Hb activation level in the frontal pole area of the prefrontal lobe, significantly improved in the CPCT group during the three cognitive tasks, whereas the CCT group showed no change. These findings indicated that CPCT endowed greater advantages in task-switching in the behavioral performance of the executive function than CCT. Moreover, CPCT was superior to CCT in increasing task-efficient cerebral oxygenation during the activation of the prefrontal cortex in adolescent shooting athletes.

通过体育和认知训练提高个体执行功能是体育和认知科学的研究热点。然而,很少有研究评估身体和认知联合训练(CPCT)是否比单独的认知训练对青少年运动员的执行功能表现和脑氧合有更大的益处。本研究将33名青少年射击运动员随机分配到CPCT(n​=​17) 或计算机化认知训练(CCT,n​=​16) 并比较了六周训练后的执行功能。所有受试者在训练前后均采用双背、任务切换和Stroop测试进行评估。在执行这三项任务时,使用功能性近红外光谱监测前额叶皮层含氧血红蛋白(Oxy-Hb)的激活水平。我们的结果表明,CPCT和CCT组类似地改进了它们的更新功能,如2-背任务精度所示。CPCT组在任务切换测试准确性上显著提高了切换功能,而CCT组则没有。然而,正如Stroop任务中的抑制功能所表明的那样,两组的行为表现都没有改善。在三项认知任务中,CPCT组的大脑氧合(由前额叶额叶极区的oxy-Hb激活水平表示)显著改善,而CCT组没有变化。这些发现表明,在执行功能的行为表现中,CPCT在任务转换方面比CCT具有更大的优势。此外,在青少年射击运动员前额叶皮层激活过程中,CPCT在提高任务有效性脑氧合方面优于CCT。

Physical activity engagement results in a variety of positive health outcomes, including a reduction in cardiovascular disease risk partially due to eccentric remodeling of the heart. The purpose of this investigation was to determine if four replicate lines of High Runner mice that have been selectively bred for voluntary exercise on wheels have a cardiac phenotype that resembles the outcome of eccentric remodeling. Adult females (average age 55 days) from the 4 High Runner and 4 non-selected control lines were anaesthetized via vaporized isoflurane, then echocardiographic images were collected and analyzed for structural and functional differences. High Runner mice in general had lower ejection fractions compared to control mice lines (2-tailed p ​= ​0.023 6) and tended to have thicker walls of the anterior portion of the left ventricle (p ​= ​0.065). However, a subset of the High Runner individuals, termed mini-muscle mice, had greater ejection fraction (p ​= ​0.000 6), fractional shortening percentage (p ​< ​0.000 1), and ventricular mass at dissection (p ​< ​0.002 7 with body mass as a covariate) compared to non-mini muscle mice. Mice from replicate lines bred for high voluntary exercise did not all have inherent positive cardiac functional or structural characteristics, although a genetically unique subset of mini-muscle individuals did have greater functional cardiac characteristics, which in conjunction with their previously described peripheral aerobic enhancements (e.g., increased capillarity) would partially account for their increased V˙ O2max.

Extensive research has been conducted on the roles of physical activity in immune functioning. However, reviews on the effect of physical activity on immune function among obese older adults are scarce. This study aimed to map the trend and development of the key terms and prominent sources to identify potential research opportunities through a systematic bibliographic analysis. A systematic search was conducted in the Scopus database on the following query: (sport∗ OR “physical activity” OR exercise) AND (elderly OR “older adult∗” OR aging) AND (immun∗) AND (obes∗) AND NOT (animal), in March 2023. Publication timing and citation were descriptively analyzed, followed by the bibliographic coupling and the term co-occurrence analyses for generating network and overlay visualization mapping using the VOSviewers software. The search resulted in 426 articles dating back from 1991 to the present and were dominated by authors from Western countries. Three thematic clusters of this research area were generated, covering (1) the impact of physical activity or inactivity on health, (2) physical activity assessments and the use of association and cross-sectional study as the primary type of research, and (3) the physical activity impacts at the population level. For future research, more intervention studies are needed to understand how exercise affects immune response in older obese adults and to explore optimal duration, type, and intensity of the exercise, using a multi-omics approach. Studies in non-Western populations and systematic reviews are recommended to complement this bibliographic analysis.

人们对体育活动在免疫功能中的作用进行了广泛的研究。然而,关于体育活动对肥胖老年人免疫功能影响的综述很少。本研究旨在通过系统的文献分析,绘制关键术语和突出来源的趋势和发展图,以确定潜在的研究机会。2023年3月,在Scopus数据库中对以下查询进行了系统搜索:(运动*或“身体活动”或锻炼)AND(老年人或“老年人”或衰老)AND(免疫*)AND(obes*)AND NOT(动物)。对出版时间和引文进行了描述性分析,然后进行了书目耦合和术语共现分析,以使用VOSviewers软件生成网络和覆盖可视化映射。搜索得到了426篇可以追溯到1991年至今的文章,这些文章主要由西方国家的作者撰写。该研究领域产生了三个专题组,涵盖(1)体育活动或不活动对健康的影响,(2)体育活动评估以及将关联和横断面研究作为主要研究类型的使用,以及(3)体育活动对人口层面的影响。对于未来的研究,需要更多的干预研究来了解运动如何影响老年肥胖成年人的免疫反应,并使用多组学方法探索运动的最佳持续时间、类型和强度。建议对非西方人群的研究和系统综述来补充这一文献分析。

This study investigated the incidence of sport-related concussion (SRC) in sports, effect of athlete knowledge on reporting behavior differences between collegiate and non-collegiate athletes, and differences in SRC symptoms between sexes and level of participation. In this cross-sectional survey, 1 344 Japanese collegiate and non-collegiate athletes from a single institute were analyzed. Using a web-based survey, demographics, general SRC, knowledge of SRC, the most recent SRC reporting behaviors, and symptom presentation were examined. The prevalence of SRC during the academic year 2016–2017 was 2.68 (95% confidence interval [CI]: 1.88–3.69) across all sports. The prevalence of SRC was 33.3 (95% CI: 17.96–51.83) in rugby union and 8.33 (95% CI: 1.03–27.00) in women's soccer. The prevalence of SRC in males (3.47 [95% CI: 2.38–4.86] was 3.65 times higher than that in females (0.95 [95% CI: 0.26–2.41]). In total, the mean total score of knowledge was 5.30 (4.2) across 25 questions; dizziness was the most well-known symptom (867/1 344, 64.5%), followed by headache (59.3%). Being more emotional (44/1 345, 3.3%) was the least frequently known symptom. Level of participation did not affect scores (5.16 [3.96] vs. 5.52 [4.54]; p ​= ​0.131). All 87 disclosing participants experienced drowsiness and irritability and felt more emotional. In terms of sex and participant level, no significant differences were found in any symptoms. This study found very low rates of concussion education in Japan. Dissemination of concussion education is essential in the future to recognize concussion earlier and prevent severe concussive injury.

本研究调查了运动中运动相关脑震荡(SRC)的发生率、运动员知识对大学和非大学运动员报告行为差异的影响,以及性别和参与水平之间SRC症状的差异。在这项横断面调查中,对来自一个研究所的1344名日本大学和非大学运动员进行了分析。使用基于网络的调查,对人口统计学、一般SRC、SRC知识、最近的SRC报告行为和症状表现进行了检查。2016-2017学年,所有运动项目的SRC患病率为2.68(95%置信区间[CI]:1.88-3.69)。SRC的患病率在橄榄球联盟为33.3(95%CI:17.96-51.83),在女子足球中为8.33(95%CI:1.03-27.00)。SRC在男性中的患病率(3.47[95%CI:2.38-4.86])是女性的3.65倍(0.95[95%CI:0.26-2.41])。总共,25个问题的平均知识总分为5.30(4.2);头晕是最常见的症状(867/1344,64.5%),其次是头痛(59.3%)。情绪化(44/1345,3.3%)是最不常见的症状。参与程度不影响分数(5.16[3.96]对5.52[4.54];p​=​0.131)。所有87名披露的参与者都经历了嗜睡和易怒,情绪更加激动。在性别和参与者水平方面,没有发现任何症状的显著差异。这项研究发现,日本的脑震荡教育率非常低。传播脑震荡教育对于早期识别脑震荡和预防严重脑震荡损伤至关重要。

To verify systematically the association between the status of physical fitness and the risk of severe Coronavirus disease 2019 (COVID-19). This systematic review is in accordance with the Preferred Reporting Items for Systematic Review and Meta Analyses (PRISMA) statement and the eligibility criteria followed the Population, Intervention, Comparison, Outcomes and Study (PICOS) recommendation. PubMed, Embase, SciELO and Cochrane electronic databases were searched. All studies that explored the relationship between the pattern of physical fitness and COVID-19 adverse outcomes (hospitalization, intensive care unit admission, intubation, or mortality), were selected. The quality of the studies was assessed by the specific scale of the Newcastle–Ottawa Scale. A total of seven observational studies were identified in this systematic review; 13 ​468 patients were included in one case-control study, two cohort studies, and four cross-sectional studies. All studies reported an inverse association between high physical fitness and severe COVID-19 (hospitalization, intensive care admission, or mortality). Only some studies reported comorbidities, especially obesity and cardiovascular disorders, but the results remained unchanged after controlling for comorbidities. The quality of the seven studies included was moderate according to the Newcastle-Ottawa Quality Assessment Scale. The methodological heterogeneity of the studies included did not allow a meta-analysis of the findings. In conclusion, higher physical fitness levels were associated with lower risk of hospitalization, intensive care admissions, and mortality rates among patients with COVID-19.

系统地验证身体健康状况与2019年严重冠状病毒疾病(新冠肺炎)风险之间的关联。该系统审查符合系统审查和荟萃分析的首选报告项目(PRISMA)声明,资格标准遵循人群、干预、比较、结果和研究(PICOS)建议。检索PubMed、Embase、SciELO和Cochrane电子数据库。所有探索体能模式与新冠肺炎不良后果(住院、重症监护室入院、插管或死亡率)之间关系的研究都被选中。研究质量采用纽卡斯尔-渥太华量表的特定量表进行评估。本系统综述共确定了7项观察性研究;13​468名患者被纳入一项病例对照研究、两项队列研究和四项横断面研究。所有研究都报告了高体能与严重新冠肺炎(住院、重症监护入院或死亡率)之间的反比关系。只有一些研究报告了合并症,尤其是肥胖和心血管疾病,但在控制了合并症后,结果保持不变。根据纽卡斯尔-渥太华质量评估量表,纳入的七项研究的质量中等。纳入研究的方法学异质性不允许对研究结果进行荟萃分析。总之,新冠肺炎患者较高的身体素质水平与较低的住院风险、重症监护入院风险和死亡率相关。

This study compares the physical activity levels and enjoyment of parents (n ​= ​50; age ​= ​41.8 ​± ​4.0 years) during outdoor, self-paced walking sessions while walking alone and when walking with their 6-to-12-year-old child. Step counts, moderate-to-vigorous physical activity (MVPA), vigorous physical activity, and enjoyment were compared using paired t-tests. Regression modeling was used to examine the impact of children's age and adults' and children's body mass index on the disparity in step counts experienced by adults. Adults attained high percentages of time spent in MVPA while walking alone (99.8%) and when walking with their child (96.6%). However, more of this time was categorized as vigorous physical activity when walking alone (13.6% vs. 3.0%, p ​= ​0.006). Adults' step counts decreased by an average of 6.4% while walking with their child compared to walking alone (p ​< ​0.001). This reduction was greater for parents of younger children (p ​= ​0.004). In obese adults, the reduction in step counts experienced while walking with their child was not as great as the reduction experienced by normal-weight adults (p ​= ​0.042). Although adults obtained higher step counts and vigorous physical activity while walking alone, they enjoyed walking more with their child (p ​< ​0.001). Health practitioners should be aware of this tradeoff when making recommendations for parent-child co-participation in physical activity, and parents may wish to supplement their physical activity obtained while walking with their child(ren) with additional activities that result in vigorous physical activity.

本研究比较了父母(n​=​50;年龄​=​41.8​±​4.0岁)在户外自行行走时,独自行走时以及与6至12岁的孩子一起行走时。使用配对t检验比较步数、中等至剧烈体力活动(MVPA)、剧烈体力活动和快乐。回归模型用于检验儿童年龄、成人和儿童体重指数对成人步数差异的影响。成年人在单独行走时(99.8%)和与孩子一起行走时(96.6%)在MVPA中花费的时间比例很高。然而,单独行走时更多的时间被归类为剧烈的体育活动(13.6%对3.0%,p​=​0.006)。与独自行走相比,成年人与孩子一起行走时的步数平均下降了6.4%(p​p​=​0.004)。在肥胖的成年人中,与孩子一起走路时的步数减少不如正常体重的成年人(p​=​0.042)。尽管成年人在独自行走时获得了更高的步数和剧烈的体育活动,但他们更喜欢与孩子一起行走(p​

We purpose to determine the nationality of the European middle-distance athletes under 18 years (U18) and under 20 years (U20) during the last decade, to verify the participation trend for each country, and to assess whether the place of competition can be associated with the athletes ranking position. The sample comprised 902 European male runners, ranked among the best finishers from 2009 to 2020. The athletes were divided into two categories (nU18 ​= ​266; and nU20 ​= ​636) of two distances (n1 500 ​m ​= ​397; n3 000 ​m ​= ​505). The Mantel test was used for participation trend and the Chi-square test (χ2) was used to verify differences between the ranking position and the place of competition. For both distances, the highest number of athletes were from Spain (n = 127), followed by Turkey (n = 62) and Great Britain (n = 50). No significant trends were shown for most of the countries, in both distances. A positive trend was shown for Slovenia (i.e., 3000 ​m) over the years. A non-significant association was verified between the countries and the ranking position, as non-significant differences were proved for the place of competition. This information may be useful to guide athlete development programs in each country.

我们的目的是确定过去十年中18岁以下(U18)和20岁以下(U20)的欧洲中距离运动员的国籍,验证每个国家的参赛趋势,并评估比赛地点是否与运动员的排名位置相关。样本包括902名欧洲男性跑步者,他们在2009年至2020年的最佳成绩中名列前茅。运动员被分为两类(nU18​=​266;和nU20​=​636)的两个距离(n1500​m​=​397;N3000​m​=​505)。Mantel检验用于参与趋势,卡方检验(χ2)用于验证排名位置和比赛地点之间的差异。在这两个距离上,西班牙的运动员人数最多(n=127),其次是土耳其(n=62)和英国(n=50)。在这两个距离上,大多数国家都没有显示出显著的趋势。斯洛文尼亚出现了积极的趋势(即3000​m) 多年来。各国与排名位置之间的关联不显著,因为竞争地点的差异不显著。这些信息可能有助于指导每个国家的运动员发展计划。
