The discovery that contracting skeletal muscle generates reactive oxygen species (ROS) was first reported over 40 years ago. The prevailing view in the 1980s was that exercise-induced ROS production promotes oxidation of proteins and lipids resulting in muscle damage. However, a paradigm shift occurred in the 1990s as growing research revealed that ROS are signaling molecules, capable of activating transcriptional activators/coactivators and promoting exercise-induced muscle adaptation. Growing evidence supports the notion that reduction-oxidation (redox) signaling pathways play an important role in the muscle remodeling that occurs in response to endurance exercise training. This review examines the specific role that redox signaling plays in this endurance exercise-induced skeletal muscle adaptation. We begin with a discussion of the primary sites of ROS production in contracting muscle fibers followed by a summary of the antioxidant enzymes involved in the regulation of ROS levels in the cell. We then discuss which redox-sensitive signaling pathways promote endurance exercise-induced muscle adaptation and debate the strength of the evidence supporting the notion that redox signaling plays an essential role in muscle adaptation to endurance exercise training. In hopes of stimulating future research, we highlight several important unanswered questions in this field.

40 多年前,人们首次发现收缩的骨骼肌会产生活性氧(ROS)。20 世纪 80 年代的主流观点认为,运动诱发的 ROS 会促进蛋白质和脂质氧化,从而导致肌肉损伤。然而,随着越来越多的研究发现,ROS 是一种信号分子,能够激活转录激活因子/共激活因子,并促进运动诱导的肌肉适应,因此在 20 世纪 90 年代发生了范式转变。越来越多的证据表明,还原-氧化(氧化还原)信号通路在耐力运动训练所引起的肌肉重塑过程中发挥着重要作用。本综述探讨了氧化还原信号在这种耐力运动诱导的骨骼肌适应中发挥的具体作用。我们首先讨论了收缩肌纤维中产生 ROS 的主要部位,然后总结了参与调节细胞中 ROS 水平的抗氧化酶。然后,我们讨论了哪些对氧化还原反应敏感的信号传导途径可促进耐力运动引起的肌肉适应,并就支持氧化还原反应信号传导在肌肉适应耐力运动训练中发挥重要作用这一观点的证据的强度进行了辩论。为了激励未来的研究,我们强调了这一领域的几个重要未解之谜。

Background: Newly diagnosed breast cancer patients experience symptoms that may affect their quality of life, treatment outcomes, and survival. Preventing and managing breast cancer-related symptoms soon after diagnosis is essential. The purpose of this study was to investigate the associations between health-related fitness (HRF) and patient-reported symptoms in newly diagnosed breast cancer patients.

Methods: This study utilized baseline data from the Alberta Moving Beyond Breast Cancer Cohort Study that were collected within 90 days of diagnosis. HRF measures included peak cardiopulmonary fitness (peak volume of oxygen consumption (VO2peak)), maximal muscular strength and endurance, flexibility, and body composition. Symptom measures included depression, sleep quality, and fatigue. Adjusted multivariable logistic regression was performed for analyses.

Results: Of 1458 participants, 51.5% reported poor sleep quality, 26.5% reported significant fatigue, and 10.4% reported moderate depression. In multivariable-adjusted models, lower relative VO2peak was independently associated with a greater likelihood of all symptom measures, including moderate depression (p < 0.001), poor sleep quality (p = 0.009), significant fatigue (p = 0.008), any symptom (p < 0.001), and multiple symptoms (p < 0.001). VO2peak demonstrated threshold associations with all symptom measures such that all 3 lower quartiles exhibited similar elevated risk compared to the highest quartile. The strength of the threshold associations varied by the symptom measure with odds ratios ranging from ∼1.5 for poor sleep quality to ∼3.0 for moderate depression and multiple symptoms. Moreover, lower relative upper body muscular endurance was also independently associated with fatigue in a dose-response manner (p = 0.001), and higher body weight was independently associated with poor sleep quality in an inverted U pattern (p = 0.021).

Conclusion: Relative VO2peak appears to be a critical HRF component associated with multiple patient-reported symptoms in newly diagnosed breast cancer patients. Other HRF parameters may also be important for specific symptoms. Exercise interventions targeting different HRF components may help newly diagnosed breast cancer patients manage specific symptoms and improve outcomes.

背景:新确诊的乳腺癌患者会出现一些症状,这些症状可能会影响他们的生活质量、治疗效果和生存期。在确诊后尽快预防和控制乳腺癌相关症状至关重要。本研究旨在调查新诊断乳腺癌患者的健康相关体能(HRF)与患者报告症状之间的关联:本研究利用了阿尔伯塔省超越乳腺癌(AMBER)队列研究的基线数据,这些数据是在确诊后 90 天内收集的。HRF测量指标包括心肺功能峰值(VO2峰值)、最大肌肉力量和耐力、柔韧性和身体成分。症状测量包括抑郁、睡眠质量和疲劳。分析结果采用调整后的多变量逻辑回归法:在 1458 名参与者中,51.5% 报告睡眠质量差,26.5% 报告明显疲劳,10.4% 报告中度抑郁。在多变量调整模型中,相对 VO2 峰值越低,出现所有症状的可能性越大,包括中度抑郁(p < 0.001)、睡眠质量差(p = 0.009)、明显疲劳(p = 0.008)、任何症状(p < 0.001)和多种症状(p < 0.001)。VO2peak 与所有症状指标都有阈值关联,因此与最高四分位数相比,所有三个较低的四分位数都表现出类似的风险升高。阈值关联的强度因症状测量而异,几率比从睡眠质量差的∼1.5到中度抑郁和多种症状的∼3.0不等。此外,相对较低的上半身肌肉耐力也以剂量反应的方式与疲劳独立相关(p = 0.001),而较高的体重则以倒 U 型模式与睡眠质量差独立相关(p = 0.021):结论:在新诊断的乳腺癌患者中,相对 VO2 峰值似乎是与患者报告的多种症状相关的关键心率变异成分。其他心率变异参数可能对特定症状也很重要。针对不同心率变异成分的运动干预可帮助新诊断的乳腺癌患者控制特定症状并改善预后。

Risk factors for running-related injuries: An umbrella systematic review. 跑步相关伤害的风险因素:总括性系统综述。
IF 9.7 1区 医学 Q1 HOSPITALITY, LEISURE, SPORT & TOURISM Pub Date : 2024-11-01 Epub Date: 2024-04-30 DOI: 10.1016/j.jshs.2024.04.011

Purpose: This umbrella systematic review (SR) of SRs and meta-analysis seeks to comprehensively synthesize existing literature to identify and consolidate the diverse range of risk factors contributing to running-related injuries (RRIs).

Methods: Systematic searches were conducted on June 28, 2023, across Web of Science, SPORTDiscus, Scopus, PubMed, and Cochrane Library. We included SRs, whether accompanied by meta-analyses or not, that focused on investigating risk factors for RRIs within observational studies. The methodological quality of the SRs was evaluated using the Assessing the Methodological Quality of Systematic Reviews II. To assess the extent of overlap across reviews, the corrected covered area metric was calculated.

Results: From 1509 records retrieved, 13 SRs were included. The degree of overlap between SRs was low (4%), and quality varied from critically low (n = 8) to low (n = 5). Two hundred seven outcomes assessed in 148 primary studies were identified as being associated with the occurrence of RRIs. The effect sizes of the associations for which risk measures were reported (n = 131) were classified as large (n = 30, 23%), medium (n = 38, 29%), small (n = 48, 37%) or no effect (n = 15, 11%). Running/training characteristics, health and lifestyle factors, along with morphological and biomechanical aspects, exhibit large effect sizes in increasing the risk for RRIs.

Conclusion: Drawing from the outcomes of the low-quality SRs and associations with large effect sizes, our findings indicate that running/training characteristics and health and lifestyle factors, as well as morphological and biomechanical aspects, are all implicated in elevating the risk of RRIs, emphasizing the multifactorial basis of injury incidence in running. Given the low quality and heterogeneity of SR, individual findings warrant cautious interpretation.

目的:这一总括性系统综述和荟萃分析旨在全面综合现有文献,以识别和整合导致跑步相关损伤(RRIs)的各种风险因素:我们于 2023 年 6 月 28 日在 Web of Science、SPORTDiscus、Scopus、PubMed 和 Cochrane Library 上进行了系统检索。我们纳入了系统综述(SR),无论是否伴有荟萃分析,这些综述都侧重于在观察性研究中调查跑步相关损伤的风险因素。系统综述的方法学质量采用系统综述方法学质量评估 II (AMSTAR 2) 进行评估。为了评估各篇综述的重叠程度,计算了校正覆盖面积指标:从检索到的 1509 条记录中,共纳入了 13 篇系统综述。研究报告之间的重叠程度较低(4%),质量从 "极低"(8 项)到 "低"(5 项)不等。在 148 项主要研究中,有 27 项评估结果与 RRI 的发生有关。已报告风险测量结果的关联效应大小(n = 131)分为大效应(n = 30,23%)、中效应(n = 38,29%)、小效应(n = 48,37%)或无效应(n = 15,11%)。跑步/训练特点、健康和生活方式因素以及形态和生物力学方面的因素在增加RRIs风险方面显示出较大的效应大小:我们的研究结果表明,跑步/训练特点、健康和生活方式因素以及形态学和生物力学方面的因素都与 RRI 风险的增加有关,这强调了跑步损伤发生率的多因素基础。鉴于SR的低质量和异质性,个别研究结果需要谨慎解读。

The association of diet quality and physical activity with cardiovascular disease and mortality in 85,545 older Australians: A longitudinal study. 85,545 名澳大利亚老年人的饮食质量和体育锻炼与心血管疾病和死亡率的关系:一项纵向研究。
IF 9.7 1区 医学 Q1 HOSPITALITY, LEISURE, SPORT & TOURISM Pub Date : 2024-11-01 Epub Date: 2024-05-28 DOI: 10.1016/j.jshs.2024.05.011

Background: A quality diet and an active lifestyle are both important cornerstones of cardiovascular disease (CVD) prevention. However, despite their interlinked effects on metabolic health, the 2 behaviors are rarely considered jointly, particularly within the context of CVD prevention. We examined the independent, interactive, and joint associations of diet and physical activity with CVD hospitalization, CVD mortality, and all-cause mortality.

Methods: CVD-free Australian participants aged 45-74 years (n = 85,545) reported physical activity, diet, sociodemographic, and lifestyle characteristics at baseline (2006-2009) and follow-up (2012-2015), and data were linked to hospitalization and death registries (03/31/2019 for CVD hospitalization and all-cause mortality and 12/08/2017 for CVD mortality). Diet quality was categorized as low, medium, and high based on meeting dietary recommendations. Physical activity was operationalized as (a) total moderate-to-vigorous physical activity (MVPA) as per guidelines, and (b) the composition of MVPA as the ratio of vigorous-intensity physical activity (VPA) to total MVPA. We used a left-truncated cause-specific Cox proportional hazards model using time-varying covariates.

Results: During a median of 10.7 years of follow-up, 6576 participants were admitted to the hospital for CVD and 6581 died from all causes (876 from CVD during 9.3 years). A high-quality diet was associated with a 17% lower risk of all-cause mortality than a low-quality diet, and the highest MVPA category (compared with the lowest) was associated with a 44% and 48% lower risk of CVD and all-cause mortality, respectively. Multiplicative interactions between diet and physical activity were non-significant. For all outcomes, the lowest risk combinations involved a high-quality diet and the highest MVPA categories. Accounting for total MVPA, some VPA was associated with further risk reduction of CVD hospitalization and all-cause mortality.

Conclusion: For CVD prevention and longevity, one should adhere to both a healthy diet and an active lifestyle and incorporate some VPA when possible.

背景:优质饮食和积极的生活方式都是预防心血管疾病(CVD)的重要基石。然而,尽管这两种行为对代谢健康有着相互关联的影响,但却很少被联合考虑,尤其是在心血管疾病预防方面。我们研究了饮食和体育锻炼与心血管疾病住院率、心血管疾病死亡率和全因死亡率的独立、交互和联合关系:年龄在 45-74 岁之间、无心血管疾病的澳大利亚参与者(n = 85,545)在基线(2006-2009 年)和随访(2012-2015 年)时报告了体育锻炼、饮食以及社会人口学和生活方式特征,数据与住院和死亡登记(心血管疾病住院和全因死亡率为 2019 年 3 月 31 日,心血管疾病死亡率为 2017 年 12 月 8 日)相连。饮食质量根据是否符合饮食建议分为低、中和高。体力活动的操作方法是:(a) 根据指南进行总的中强度体力活动 (MVPA);(b) MVPA 的构成是剧烈强度体力活动 (VPA) 与总 MVPA 之比。我们使用了一个左截断的特定原因 Cox 比例危险模型,并使用了随时间变化的协变量:在中位 10.7 年的随访期间,6581 名参与者因心血管疾病入院,6586 人死于各种原因(其中 879 人在 9.3 年中死于心血管疾病)。与低质量饮食相比,高质量饮食导致的全因死亡风险降低了 17%,最高 MVPA 类别(与最低 MVPA 类别相比)导致的心血管疾病和全因死亡风险分别降低了 44% 和 48%。饮食与体力活动之间的乘法交互作用不显著。在所有结果中,风险最低的组合涉及高质量饮食和最高 MVPA 类别。考虑到总的 MVPA,一些 VPA 与进一步降低心血管疾病住院风险和全因死亡率有关:结论:为了预防心血管疾病和延年益寿,人们应该坚持健康饮食和积极的生活方式,并在可能的情况下加入一些 VPA。

Revisiting the stretch-induced force deficit: A systematic review with multilevel meta-analysis of acute effects. 重新审视拉伸引起的力量不足:对急性效应进行系统回顾和多层次荟萃分析:重新审视拉伸引起的力量不足。
IF 9.7 1区 医学 Q1 HOSPITALITY, LEISURE, SPORT & TOURISM Pub Date : 2024-11-01 Epub Date: 2024-05-10 DOI: 10.1016/j.jshs.2024.05.002

Background: When recommending avoidance of static stretching prior to athletic performance, authors and practitioners commonly refer to available systematic reviews. However, effect sizes (ES) in previous reviews were extracted in major part from studies lacking control conditions and/or pre-post testing designs. Also, currently available reviews conducted calculations without accounting for multiple study outcomes, with ES: -0.03 to 0.10, which would commonly be classified as trivial.

Methods: Since new meta-analytical software and controlled research articles have appeared since 2013, we revisited the available literatures and performed a multilevel meta-analysis using robust variance estimation of controlled pre-post trials to provide updated evidence. Furthermore, previous research described reduced electromyography activity-also attributable to fatiguing training routines-as being responsible for decreased subsequent performance. The second part of this study opposed stretching and alternative interventions sufficient to induce general fatigue to examine whether static stretching induces higher performance losses compared to other exercise routines.

Results: Including 83 studies with more than 400 ES from 2012 participants, our results indicate a significant, small ES for a static stretch-induced maximal strength loss (ES = -0.21, p = 0.003), with high magnitude ES (ES = -0.84, p = 0.004) for stretching durations ≥60 s per bout when compared to passive controls. When opposed to active controls, the maximal strength loss ranges between ES: -0.17 to -0.28, p < 0.001 and 0.040 with mostly no to small heterogeneity. However, stretching did not negatively influence athletic performance in general (when compared to both passive and active controls); in fact, a positive effect on subsequent jumping performance (ES = 0.15, p = 0.006) was found in adults.

Conclusion: Regarding strength testing of isolated muscles (e.g., leg extensions or calf raises), our results confirm previous findings. Nevertheless, since no (or even positive) effects could be found for athletic performance, our results do not support previous recommendations to exclude static stretching from warm-up routines prior to, for example, jumping or sprinting.

背景:当建议避免在运动表现前进行静态拉伸时,作者和从业人员通常会参考现有的系统综述。然而,以往综述中的效应大小(ES)主要是从缺乏对照条件和/或前后测试设计的研究中提取的。此外,目前可用的综述在进行计算时未考虑多项研究结果,ES值为-0.03至0.10,通常被归类为微不足道:由于自2013年以来出现了新的荟萃分析软件和对照研究文章,我们重新审视了现有文献,并利用对照前后试验的稳健方差估计进行了多层次荟萃分析,以提供最新证据。此外,之前的研究表明,肌电图活动减少(也可归因于疲劳训练)是导致后续表现下降的原因。本研究的第二部分对拉伸和其他足以引起全身疲劳的干预措施进行了对比,以考察静态拉伸与其他锻炼方法相比是否会引起更高的成绩下降:我们的结果表明,与被动对照组相比,静态拉伸诱发最大力量损失的ES显著而较小(ES = -0.21,p = 0.003),拉伸持续时间≥60秒/次的ES较高(ES = -0.84,p = 0.004)。与主动对照组相比,最大力量损失介于 ES:-0.17 至 -0.28,p < 0.001 和 0.040 之间,大部分没有异质性或异质性很小。然而,拉伸对运动成绩总体上没有负面影响(与被动和主动对照组相比);事实上,在成人中发现拉伸对随后的跳跃成绩有积极影响(ES = 0.15,p = 0.006):结论:关于孤立肌肉的力量测试(如腿部伸展或小腿上举),我们的结果证实了之前的研究结果。尽管如此,由于没有发现静态拉伸对运动表现有影响(甚至是积极的),我们的结果并不支持之前的建议,即在跳跃或短跑等运动前的热身过程中不进行静态拉伸。
