    许多今天的休闲跑步者已经改变了他们的饮食从杂食到素食或素食主义者的原因,如更好的运动表现,动物伦理,积极的健康,生态方面,或者男性不育。由于当前可持续饮食的趋势,其他人已经建立了弹性饮食。这项调查的目的是根据当前的可持续饮食趋势分析休闲耐力跑步者的饮食习惯和比赛日策略。休闲耐力跑步者(18岁以上)被邀请完成关于社会人口统计学/人体测量学的标准化在线调查,动机,跑步/赛车历史,食物频率,和比赛日饮食策略。采用卡方检验和Wilcoxon检验进行统计分析。总的来说,289名参与者提交了调查;146名受试者遵循弹性主义(n=34),素食主义者(n=50),或素食(n=62)饮食包括在最终样本中。饮食类型之间存在显着差异:BMI(p=0.018),水果/蔬菜消费量(p<0.001),和表现的饮食动机(p=0.045)。研究结果表明,弹性饮食可能适合生活在以肉类为中心的社会中,缺乏社会支持而完全吃素/素食主义者的健康和环保意识人群。遵循植物性饮食被认为是健康意识的容易,运动人群,和素食饮食不需要一个特别费力/复杂的比赛日策略耐力跑步。
    Many of today\'s recreational runners have changed their diet from omnivorous to vegetarian or vegan for reasons like better sport performance, animal ethics, positive health, eco-aspects, or male infertility. Others have constructed the flexitarian diet due to current trends in sustainable eating. The aim of this investigation was to analyze the dietary habits and race day strategies of recreational endurance runners following current sustainable dietary trends. Recreational endurance runners (18+ years) were invited to complete the standardized online survey on socio-demography/anthropometry, motivations, running/racing history, food frequency, and race day dietary strategy. Chi-squared tests and Wilcoxon tests were used for the statistical analysis. In total, 289 participants submitted the survey; 146 subjects following flexitarian (n = 34), vegetarian (n = 50), or vegan (n = 62) diets were included in the final sample. Significant differences were found across the diet types: BMI (p = 0.018), fruit/vegetable consumption (p < 0.001), and the dietary motive of performance (p = 0.045). The findings suggest that the flexitarian diet may be appropriate for health- and environmentally conscious populations living in a meat-centered society and lacking social support to eat completely vegetarian/vegan. Following a plant-based diet is perceived as easy for health-conscious, athletic populations, and the vegan diet does not require a particularly effortful/complex race day strategy for endurance runners.

    最近所有距离的精英跑步表现的改善在很大程度上归因于先进鞋类技术(AFT)的引入,其特点是弯曲和坚硬的板与新一代的鞋底夹层泡沫协同作用,表现出增强的弹性和顺应性。这些最近的改善在女性活动中似乎更加明显,公路赛车世界纪录平均提高了3.7%(范围:2.6%-5.2%),而在同一男子比赛中平均进步了1.5%(范围:1.3%-1.9%)。尽管有越来越多的研究机构调查了从AFT派生的运行性能增强的机制,对于她们的获益可能存在的性别差异,目前尚无解释.我们概述了当前可用的证据,并强调了为什么AFT研究的最新方向通过主要关注男性运动员而为进步提供了障碍。随后,我们提供了我们的观点,说明为什么女性可能比男性更受益于新一代鞋子,提出了导致假设的潜在机制,需要在即将进行的研究中进一步研究,最后提出,鞋类创新之外的因素可能同时推动了最近观察到的性能演变。
    Recent improvements in elite running performances across all distances have been largely attributed to the introduction of advanced footwear technology (AFT), which features a curved and stiff plate working synergistically with a new generation of midsole foams demonstrating enhanced resilience and compliance. These recent improvements appear to be considerably more pronounced in women\'s events, highlighted by improvements in road racing world records by an average of 3.7% (range: 2.6%-5.2%) compared to mean progressions of 1.5% (range: 1.3%-1.9%) in the same men\'s events. Although there is a growing body of research investigating the mechanisms underpinning running performance enhancements derived from AFT, there remains no explanation for potential sex-based differences in their benefits. We overview the currently available evidence and highlight why the recent direction of AFT research provides a barrier to progress by focusing primarily on male athletes. We subsequently provide our perspective on why women may be benefiting from the new generation of shoes more than men, suggest potential mechanisms leading to hypotheses that need to be further investigated in upcoming studies, and finally propose that factors outside of footwear innovation may have concurrently driven the recently observed performance evolutions.

    在过去的几年中,参加马拉松比赛的人数急剧增加。马拉松跑步有许多被证明的有益效果,尤其是心血管健康和健身。大多数研究集中在与耐力运动相关的生理和病理生理适应上。然而,马拉松对心理方面也有重大影响,对心理健康也有积极影响,直到最近才引起研究兴趣。本叙事评论旨在回顾马拉松运动员的个性特征,重点是最近的文献。马拉松运动员表现出成功完成如此苛刻的比赛所需的鲜明个性和高度特征性的人格特质,即,强烈的活力感,自给自足,智力和愤怒的低分,疲劳,紧张,和抑郁症。此外,在不同性别的跑步者之间可以检测到人格差异,年龄,和绩效水平组。这对运动员具有重要的临床意义,教练和比赛组织者,因为这些群体表现出不同的人格特质模式。未来的研究应该集中在认知和情绪状态的变化上,during,和后耐力事件,以及在训练期间。按性别比较人格差异的大规模研究,年龄,和性能对于更好的临床指导也很重要。另见图形摘要(图。1).
    Participation in marathons has dramatically increased over the last few years. Marathon running has many proven beneficial effects, especially on cardiovascular health and fitness. Most research has focused on physiologic and pathophysiologic adaptations in connection with endurance exercise. Nevertheless, marathon running also has a major impact on psychological aspects and positively influences mental health, which has only recently attracted research interest. The present narrative review aimed to review the personality traits of marathon runners with an emphasis on recent literature. Marathon runners show a distinct personality and highly characteristic personality traits needed to successfully finish such a demanding race, i.e., a strong sense of vigor, self-sufficiency, and intelligence as well as low scores in anger, fatigue, tension, and depression. Furthermore, personality differences are detectable between runners of different sexes, ages, and performance level groups. This has significant clinical implications for athletes, coaches and competition organizers, as these groups show different patterns of personality traits. Future studies should focus on changes in cognition and mood states pre-, during, and post-endurance events, as well as during training periods. Large-scale studies comparing personality differences by sex, age, and performance are also important for better clinical guidance. See also the graphical abstract(Fig. 1).

    马拉松跑步带来了独特的心血管挑战,有时会导致晕厥发作。我们介绍了一系列在苏黎世马拉松2023期间经历过晕厥前/晕厥的运动员,并伴有心脏生物标志物升高。
    八名运动员(两名女性,6名男性)21-35岁,伴有晕厥前/晕厥和各种其他不同的症状,如(半)马拉松期间的头晕和心悸,被送往苏黎世的两个急诊科,瑞士。临床评估包括心电图,超声心动图,遥测,冠状动脉计算机断层扫描(CT)扫描,和心脏生物标志物评估。初始评估时,所有病例的高敏肌钙蛋白T(hs-cTnT)均升高,随访时恢复正常。所有接受CT扫描的运动员的冠状动脉和脑部CT结果均正常。八名运动员中没有一名患有潜在的心血管疾病。入院后肾功能恢复正常,神经症状在数小时内消失.肌酐水平表明短暂性急性肾损伤。一个共同的特点是缺乏跑步经验,比赛准备不足,特别是关于流体,电解质,和碳水化合物的摄入,以及起搏问题和缺乏应对热量的策略。
    从临床医生的角度来看,该系列病例强调了在剧烈运动期间发生晕厥前/晕厥事件和心脏生物标志物升高的患者管理方面的挑战.不同的初始症状促使有针对性的调查。充分的训练,医学评估,和晕厥触发的意识是必不可少的马拉松参与者。谨慎和起搏策略至关重要,尤其是在竞技跑步的新手中。鉴于马拉松比赛的日益普及,此信息是相关的,并在这些比赛之后提出了标准化的诊断方法。
    UNASSIGNED: Marathon running poses unique cardiovascular challenges, sometimes leading to syncopal episodes. We present a case series of athletes who experienced pre-/syncope during the Zurich Marathon 2023, accompanied by elevated cardiac biomarkers.
    UNASSIGNED: Eight athletes (2 females, 6 males) aged 21-35 years, with pre-/syncope and various additional diverse symptoms such as dizziness and palpitations during the (half-)marathon, were admitted to two emergency departments in Zurich, Switzerland. Clinical evaluations included electrocardiogram, echocardiography, telemetry, coronary computed tomography (CT) scans, and cardiac biomarker assessments. High-sensitive troponin T (hs-cTnT) was elevated in all cases at initial assessment and returned to normal at follow-up. All athletes who received CT scans had normal coronary and brain CT results. None of the eight athletes had underlying cardiovascular disease. Renal function normalized post-admission, and neurological symptoms resolved within hours. Creatinine levels indicated transient acute kidney injury. A common feature was inexperience in running, inadequate race preparation, particularly regarding fluid, electrolyte, and carbohydrate intake, along with pacing issues and lack of coping strategies with heat.
    UNASSIGNED: From a clinician perspective, the case series highlights the challenge in the management of patients with a pre-/syncopal event during strenuous exercise and elevated cardiac biomarkers. Diverse initial symptoms prompted tailored investigations. Adequate training, medical assessments, and awareness of syncope triggers are essential for marathon participants. Caution and pacing strategies are crucial, especially among novices in competitive running. This information is pertinent given the growing popularity of marathon events and prompts a standardized diagnostic approach after these events.

    目的:我们旨在确定参加北京2022马拉松的非精英跑步者对运动反应的肌钙蛋白变化的主要决定因素,特别关注与通过组织多普勒超声心动图和斑点追踪评估的心脏功能的关联。
    方法:前瞻性研究。
    方法:将2022年北京马拉松比赛的33名非精英参与者纳入研究。之前进行超声心动图评估和血液样本收集,紧接着,马拉松比赛两周后.使用相同的Abbot高灵敏度cTnISTAT测定法分析血液样品。超声心动图包括组织多普勒和斑点追踪超声心动图。
    结果:马拉松之后,在心脏生物标志物中观察到显著增加,hs-cTnI从3.1[2.3-6.7]升至49.6[32.5-76.9]ng/L(P<0.0001)。超过72%的参与者的赛后hs-TnI水平超过第99百分位数参考上限。马拉松前hs-cTnI水平之间存在显著相关性(β系数,0.56[0.05,1.07];P=0.042),每周平均训练(β系数,-1.15[-1.95,-0.35];P=0.009),hs-cTnI在马拉松后崛起。超声心动图显示种族后明显的心功能变化,包括降低的E/A比(P<0.0001),GWI(P<0.0001),和GCW(P<0.0001),在LVEF(β系数,0.112[0.01,0.21];P=0.042)和RVGLS(β系数,0.124[0.01,0.23];P=0.035)变化与hs-TnI改变显着相关。所有超声心动图和实验室指标在两周内恢复到基线水平。
    结论:基线hs-cTnI水平和每周平均训练影响非优秀跑步者运动诱发的hs-cTnI升高。超声心动图显示种族后心功能变化,LVEF和RVGLS与hs-TnI改变显著相关。这些发现有助于了解心脏对运动的反应,并可以指导训练和恢复策略。
    OBJECTIVE: We aimed to identify the major determinants of cardiac troponin changes response to exercise among non-elite runners participating in the Beijing 2022 marathon, with a particular focus on the associations with the cardiac function assessed by tissue Doppler echocardiography and speckle tracking.
    METHODS: A prospective study.
    METHODS: A total of 33 non-elite participants in the 2022 Beijing Marathon were included in the study. Echocardiographic assessment and blood sample collection were conducted before, immediately after, and two weeks after the marathon. Blood samples were analyzed using the same Abbot high-sensitivity cTnI STAT assay. Echocardiography included tissue Doppler and speckle tracking echocardiography.
    RESULTS: Following the marathon, significant increases were observed in cardiac biomarkers, with hs-cTnI elevating from 3.1 [2.3-6.7] to 49.6 [32.5-76.9] ng/L (P < 0.0001). Over 72 % of participants had post-race hs-TnI levels surpassing the 99th percentile upper reference limit. There was a notable correlation between pre-marathon hs-cTnI levels (β coefficient, 0.56 [0.05, 1.07]; P = 0.042), weekly average training (β coefficient, -1.15 [-1.95, -0.35]; P = 0.009), and hs-cTnI rise post-marathon. Echocardiography revealed significant post-race cardiac function changes, including decreased E/A ratio (P < 0.0001), GWI (P < 0.0001), and GCW (P < 0.0001), with LVEF (β coefficients, 0.112 [0.01, 0.21]; P = 0.042) and RV GLS (β coefficients, 0.124 [0.01, 0.23]; P = 0.035) changes significantly associated with hs-TnI alterations. All echocardiographic and laboratory indicators reverted to baseline levels within two weeks.
    CONCLUSIONS: Baseline hs-cTnI levels and weekly average training influence exercise-induced hs-cTnI elevation in non-elite runners. Echocardiography revealed post-race changes in cardiac function, with LVEF and RV GLS significantly associated with hs-TnI alterations. These findings contribute to understanding the cardiac response to exercise and could guide training and recovery strategies.

    背景:典型的培训计划是许多具有不同强度和持续时间的培训课程的混合,以实现特定目标,比如在某个时间跑马拉松.科学出版物很少提供具体信息来帮助编写全面的培训计划。本综述旨在按照92项亚精英训练计划的建议,系统地定量分析马拉松比赛前的最后12周。
    方法:我们检索了92个马拉松训练计划,并将他们的跑步训练课程与五个强度区联系起来。随后,每个训练计划根据高峰周的总跑步量分为高(>90公里/周),中部(65-90公里/周),和低(<65公里/周)训练量计划类别。
    结果:在比赛前的最后12周,建议的每周平均跑步量为108公里,59公里,43公里的高空,中间,和短距离马拉松训练计划。这些计划的强度分布遵循15-67-10-5-3%的金字塔训练结构,14-63-18-2-3%,和12-67-17-2-2%在1、2、3、4和5区,用于高,中间,和低量培训计划,分别。
    结论:通过定量分析92个推荐的马拉松训练计划,我们可以指定马拉松比赛前12周的典型建议。虽然这种方法有明显的局限性,例如没有证据证明所调查的培训计划的有效性,可以说,这是缩小科学与实践之间差距的有用策略。
    BACKGROUND: A typical training plan is a mix of many training sessions with different intensities and durations to achieve a specific goal, like running a marathon in a certain time. Scientific publications provide little specific information to aid in writing a comprehensive training plan. This review aims to systematically and quantitatively analyse the last 12 weeks before a marathon as recommended in 92 sub-elite training plans.
    METHODS: We retrieved 92 marathon training plans and linked their running training sessions to five intensity zones. Subsequently, each training plan was grouped based on the total running volume in peak week into high (> 90 km/week), middle (65-90 km/week), and low (< 65 km/week) training volume plan categories.
    RESULTS: In the final 12 weeks before a race, recommended weekly running volume averaged 108 km, 59 km, and 43 km for high, middle, and low distance marathon training plans. The intensity distribution of these plans followed a pyramidal training structure with 15-67-10-5-3%, 14-63-18-2-3%, and 12-67-17-2-2% in zones 1, 2, 3, 4, and 5, for high, middle, and low volume training plans, respectively.
    CONCLUSIONS: By quantitatively analysing 92 recommended marathon training plans, we can specify typical recommendations for the last 12 weeks before a marathon race. Whilst this approach has obvious limitations such as no evidence for the effectiveness of the training plans investigated, it is arguably a useful strategy to narrow the gap between science and practice.

    背景:先前的研究描述了与体力活动(PA)相关的各种适应性神经可塑性大脑变化。脑电图研究主要集中在短期运动期间或之后不久的影响。这是第一项研究与久坐的对照组相比,脑电图在跑步者中显示PA诱导的持久可塑性的能力的研究。
    方法:将30名经过训练的跑步者和30名年龄和性别匹配的久坐对照(SC)纳入ReCaP(跑步对认知和可塑性的影响)研究的亚群。PA使用国际身体活动问卷(IPAQ)进行测量。跑步者的静息状态脑电图是在2017年慕尼黑马拉松训练的渐缩阶段记录的。功率谱分析是使用标准的低分辨率电磁层析成像(sLORETA)进行的,包括以下频带:delta:1.5-6Hz,θ:6.5-8.0Hz,alpha1:8.5-10Hz,alpha2:10.5-12.0Hz,beta1:12.5-18.0Hz,beta2:18.5-21.0Hz,beta3:21.5-30.0Hz,和总功率(1.5-30赫兹)。
    结果:PA(IPAQ)和BMI在组间差异显著。其他包括的人口统计学参数具有可比性。统计非参数映射显示两组之间的EEG没有显着功率差异。
    结论:研究方案中的异质性,特别是在运动停止和脑电图记录之间的时间间隔以及先前研究中对脑电图的急性运动诱发影响的并置,可能是结果差异的原因。未来的研究应该在运动停止后的不同时间点以及更广泛的运动强度和形式记录EEG,以进一步探索EEG显示长期运动诱发可塑性的能力。
    BACKGROUND: Previous studies described various adaptive neuroplastic brain changes associated with physical activity (PA). EEG studies focused mostly on effects during or shortly after short bouts of exercise. This is the first study to investigate the capability of EEG to display PA-induced long-lasting plasticity in runners compared to a sedentary control group.
    METHODS: Thirty trained runners and 30 age- and sex-matched sedentary controls (SC) were included as a subpopulation of the ReCaP (Running effects on Cognition and Plasticity) study. PA was measured with the International Physical Activity Questionnaire (IPAQ). Resting-state EEG of the runners was recorded in the tapering phase of the training for the Munich marathon 2017. Power spectrum analyses were conducted using standardized low-resolution electromagnetic tomography (sLORETA) and included the following frequency bands: delta: 1.5-6 Hz, theta: 6.5-8.0 Hz, alpha1: 8.5-10 Hz, alpha2: 10.5-12.0 Hz, beta1: 12.5-18.0 Hz, beta2: 18.5-21.0 Hz, beta3: 21.5-30.0 Hz, and total power (1.5-30 Hz).
    RESULTS: PA (IPAQ) and BMI differed significantly between the groups. The other included demographic parameters were comparable. Statistical nonparametric mapping showed no significant power differences in EEG between the groups.
    CONCLUSIONS: Heterogeneity in study protocols, especially in time intervals between exercise cessation and EEG recordings and juxtaposition of acute exercise-induced effects on EEG in previous studies, could be possible reasons for the differences in results. Future studies should record EEG at different time points after exercise cessation and in a broader spectrum of exercise intensities and forms to further explore the capability of EEG in displaying long-term exercise-induced plasticity.

    门诊后肿胀的手(POTASH)是一种获得性疾病,其特征是手肿胀,拇指,手指跟着走路,徒步旅行,或跑步;没有其他身体部位肿胀。无症状的手部肿胀始于成年期,并在充分行走后复发。通常存在的POTASH的一个显着特征是积极的拳头标志,这表明受影响的人无法将手指握入手掌并形成拳头。POTASH通常在停止步行后数小时内自发解决;然而,不那么频繁,它可以持续一两天。POTASH的发病机制尚未确定。在这个案例报告中,POTASH被描述为一名成年男子和他的妹妹。这个男人的父母和他的其他两个妹妹都没有POTASH。然而,男人的妻子也会随着长时间的运动而发展POTASH;男人和他妻子的三个生物成年子女都没有POTASH。因此,基于这些观察,提示POTASH可能具有常染色体隐性遗传方式和/或散发性。
    Post ambulatory swollen hands (POTASH) is an acquired condition characterized by swelling of the hands, thumbs, and fingers following either walking, hiking, or running; no other body sites are swollen. The asymptomatic hand swelling begins in adulthood and recurs after adequate ambulation. A distinctive feature of POTASH that is often present is a positive fist sign demonstrated by the inability of the affected person to clench their fingers into the palm and form a fist. POTASH usually resolves spontaneously within a few hours after stopping ambulation; however, less frequently, it can persist for one or two days. The pathogenesis of POTASH has not been determined. In this case report, POTASH is described in an adult man and his sister. Neither the man\'s parents nor two of his other younger sisters had POTASH. However, the man\'s wife also develops POTASH with prolonged exercise; none of the three biological adult children of the man and his wife had POTASH. Therefore, based on these observations, the possibility that POTASH may have an autosomal recessive mode of inheritance and/or may be sporadic is suggested.
