    水球守门员训练的测量首先集中在心理生理变量上,而且还可以用可穿戴传感器估计外部体积。然而,关于水球守门员纵向训练监控的研究有限。
    三名女性高级国家队守门员于2021年5月至8月参加了这项研究。内部载荷是使用感知的会话等级(sRPE)定义的。使用放置在下背部的惯性测量单元(IMU)测量三轴加速度和角速度,以测量外部载荷。使用Spearman相关性探索了自我报告和IMU衍生指标之间的关系。双向ANOVA用于评估赛段类型之间和运动员之间的差异。
    总共,收集了247次会议(159次实践,67场比赛和21场热身),155个会议有完整的数据。IMU度量,比如踢的次数,跳跃次数或运动员负荷显示出彼此高度相关(ρ=0.80-0.88)。sRPE与IMU测量的球员负荷之间也存在中等相关性(ρ=0.47,95%CI=0.33-0.58)。ANOVA检验表明,运动员sRPE之间存在显着差异(p<0.01),但运动员负荷之间没有显着差异(p=0.47)。运动员和训练类型之间没有相互作用,指数得分除外(p<0.01)。
    这项研究表明,使用自我报告和IMU措施的组合,可以在水球守门员中成功进行训练负荷的监测。自我报告的结果可能会在同一场比赛中的运动员之间发生显着变化,而IMU指标因训练情况而异。最后,教练应该注意丢失的数据,因为它们会扭曲训练负荷的解释。
    UNASSIGNED: Measurement of training in water polo goalkeepers has focused first on psycho-physiological variables, but also on external volume estimated with wearable sensors. However, there are limited studies exploring training monitoring in water polo goalkeepers longitudinally.
    UNASSIGNED: Three female senior national team goalkeepers participated in this study from May to August 2021. Internal loads were defined using session rating of perceived exertion (sRPE). Tri-axial accelerations and angular velocities were measured with an inertial measurement unit (IMU) placed on the lower back to measure external loads. Relationships between self-reported and IMU-derived metrics were explored using Spearman correlations. Two-way ANOVAs were used to assess differences between session types and between athletes.
    UNASSIGNED: In total, 247 sessions were collected (159 practices, 67 matches and 21 game warm up), with 155 sessions having complete data. IMU metrics, such as number of kicks, number of jumps or player-load showed high correlation with each other (ρ = 0.80-0.88). There was also a moderate correlation (ρ = 0.47, 95% CI = 0.33-0.58) between sRPE and player-load measured with the IMU. ANOVA tests showed that there were significant differences between athletes for sRPE (p < 0.01) but not for player load (p = 0.47). There were no interactions between athletes and training types, except for index score (p < 0.01).
    UNASSIGNED: This study shows that monitoring of training loads can be performed successfully in water polo goalkeepers using a combination of self-reported and IMU measures. Self-reported outcomes can be expected to vary significantly across athletes within the same session, while IMU metrics vary across training situations. Finally, coaches should be mindful of missing data, as they can skew the interpretation of training loads.

    泳池脚趾,与运动有关的皮肤病,是由机械摩擦和水暴露引起的,导致刺激性接触性皮炎的特殊变体。这在儿童中很常见,经常误诊,很少报道。在这里,我们报告了一个7岁女孩的病例,该女孩患上了这种不寻常的摩擦性皮炎;已经做出了池脚趾诊断。外用皮质类固醇,取得了良好的效果。如果人们意识到这种皮炎的根本原因并停止触发因素,则将促进恢复和愈合过程。
    Pool toes, a sport-related dermatosis, are caused by mechanical friction and water exposure, resulting in a special variant of irritant contact dermatitis. It is common in children, often misdiagnosed, and rarely reported. Here we report a case of a 7-year-old girl who developed this unusual type of frictional dermatitis; a pool toes diagnosis has been made. With topical corticosteroids, favorable results have been achieved. The recovery and healing process will be facilitated if one is aware of the underlying causes of such dermatitis and ceases the triggering factors.

    创建了一个建模框架,用于为任何感兴趣的区域或国家开发空间上明确的水生暴露模型,以处理在下水道中的化学物质。该框架依赖于全球可用的河流流量和人口数据集,以及当地可获得的废水处理基础设施和生活用水数据集,并利用iSTREEM®化学路由算法。该框架应用于中国和日本作为案例研究国家。从WorldPop获得了空间上明确的种群数据。涵盖两个国家空间范围的河流流量来自高分辨率的地表径流网格化数据集,该数据集基于曲线数方法,并与来自HydroBASINS和HydroSHEDS数据集的流域和河流的水文网络相结合。政府来源的公开数据用于估计人均用水量和废水处理基础设施。为了演示框架,中国模型被用来预测全国河流中抗真菌药物的水平,并利用日本模型预测了河流中直链烷基苯磺酸盐的浓度。对于这两种化学品,测量值与建模值的比较显示出良好的一致性,采用线性回归分析(R2≥0.96)。本研究提出的框架提供了一种系统和强大的方法来开发空间分辨暴露模型,可以外推到任何国家或地区,通过利用模型产生的浓度分布,允许对排放的化学品进行更准确的风险评估。Integr环境评估管理2021;00:1-12。©2021SETAC。
    A modeling framework was created for the development of spatially explicit aquatic exposure models for any region or country of interest for chemicals disposed of down the drain. The framework relies on globally available data sets for river flow and population, and locally available data sets for wastewater treatment infrastructure and domestic water use, and leverages the iSTREEM® chemical routing algorithm. The framework was applied to China and Japan as case study countries. Spatially explicit population data were obtained from WorldPop. River flows covering the spatial extent of the two countries were derived from a high-resolution surface runoff gridded data set that was based on the Curve Number approach and combined with the hydrology network for catchments and rivers from HydroBASINS and HydroSHEDS data sets. Publicly available data from government sources were used for estimating per capita water use and wastewater treatment infrastructure. To demonstrate the framework, the China model was used to predict the levels of the antifungal agent climbazole in rivers across the country, and the Japan model was used to predict river concentrations of linear alkylbenzene sulfonate. For both chemicals, the comparison of measured to modeled values showed good agreement, using linear regression analysis (R2  ≥ 0.96). The framework presented in this study provides a systematic and robust approach to develop spatially resolved exposure models that can be extrapolated to any country or region, allowing more accurate risk assessment of chemicals disposed down the drain by leveraging concentration distributions generated by the model.

    Pool swimmers are susceptible to pedal dermatoses. The causes for these conditions are asteototic dermatitis, contact dermatitis, friction-induced injury, infections, keratoderma, pruritus, thermal injury, ultraviolet radiation exposure, and urticaria. The specific dermatoses include aquagenic keratoderma, aquagenic pruritus, aquagenic urticaria, cold-induced urticaria, contact urticaria, erosion interdigitalis blastomycetica, erythrasma, Mycobacterium abscessus hand and foot disease, onychomycosis, photosensitivity, pitted keratolysis, plantar verruca, pool dermatitis, pool feet, pool toes, pool water dermatitis, pseudomonas hot-foot syndrome, skin cancer, subcorneal hematoma, sunburn, swim fin dermatitis, tinea pedis, toe web infection, and xerosis. A seven-year-old girl developed erythema and superficial blisters on her feet after they were exposed to the surface of her new swimming pool. The friction-induced injury, referred to as pool toes, resulted in skin lesions not only on the plantar surface of her toes but also on the areas of her soles-including her heels-that came in contact with the rough pool surface. In addition to discussing the characteristics of pool toes, the features of the other pool-associated pedal dermatoses are reviewed.
