Professional athletes navigate a multitude of unique challenges associated to sport-specific factors (e.g., training, travel and competition) and non-sport factors (e.g., performance pressure, stress and anxiety) that can interfere with healthy sleep behaviors. Sleep plays a key role in proper biopsychosocial development as well as short- and long-term biological, physical, psychological, and cognitive health. As poor sleep quality is known to impair proper brain function, this study aimed to investigate the effect of sleep quality on a professional athlete's ability to train, recover, and perform, as well as their overall emotional and physical well-being.A cohort study was performed in 40 professional male cricket athletes from the Dutch national cricket team (mean age 26.5 ± 5.1 years). The athletes were monitored across a 22 weeks in-season training period. Sleep quality and overall emotional and physical well-being were assessed using daily sleep diaries and questionnaires which scored the readiness to train, stress levels, fatigue, muscle soreness and flu symptoms respectively. Quality of sleep and subsequent association with the consecutive elements of the well-being questionnaire were assessed through statistical using the student t-test and clinical differences with the methodology of Osoba and colleagues: <5% “no change”, 5%–10% “little change”; 10%–20% “moderate change”; and >20% “very much change”.The results demonstrated that the professional athletes assessed their sleep quality as average with a mean score of 3.4 out of 5. Lower perceived quality of sleep (<75th percentile) was correlated with a decreased readiness to train (mean score 3.2 [IQR: 3.0–4.0] vs. 3.5 [IQR: 3.0–5.0]; P < 0.001) and increased extent of muscle soreness (2.7 [IQR: 2.0–3.0] vs. 2.3 [IQR: 2–3]; P < 0.001), stress level (mean score 2.3 [IQR: 2.0–3.0] vs. 1.9 [IQR: 1.0–2.0]; P < 0.001) and perceived fatigue (mean score 2.9 [IQR: 2.0–3.0] vs. 2.3 [IQR: 2.0–3.0]; P < 0.001). Likewise, in patients with lower perceived quality of sleep, the proportion of players presenting with flu symptoms increased over 4-fold (4.1% vs. 17%; P < 0.001).This study highlights that good sleep quality positively influences the overall emotional and physical well-being of professional athletes. Our results emphasize the importance of targeted sleep interventions to improve sleep quality and subsequently optimize psychological and physiological wellness.
职业运动员要应对与运动相关的因素(如训练、旅行和比赛)和非运动因素(如成绩压力、压力和焦虑)带来的众多独特挑战,这些因素都会干扰健康的睡眠行为。睡眠对正常的生物心理社会发展以及短期和长期的生物、生理、心理和认知健康起着关键作用。众所周知,睡眠质量差会损害大脑的正常功能,因此本研究旨在调查睡眠质量对专业运动员训练、恢复和表现能力的影响,以及对他们整体情绪和身体健康的影响。该研究对来自荷兰国家板球队的 40 名专业男子板球运动员(平均年龄为 26.5 ± 5.1 岁)进行了一项队列研究。采用每日睡眠日记和调查问卷对睡眠质量以及整体情绪和身体健康进行评估,调查问卷分别对训练准备情况、压力水平、疲劳、肌肉酸痛和流感症状进行评分。通过使用学生 t 检验法进行统计,并使用 Osoba 及其同事的方法进行临床差异分析,评估了睡眠质量以及随后与幸福感问卷各连续要素之间的关联:结果表明,专业运动员对其睡眠质量的评价为一般,平均分为 3.4 分(满分 5 分)。结果表明,专业运动员对自己睡眠质量的评价为一般,平均分为 3.4 分(满分 5 分),睡眠质量较低(低于百分位数第 75 位)与训练准备程度降低(平均分为 3.2 [IQR:3.0-4.0] vs. 3.5 [IQR:3.0-5.0];P <0.001)和肌肉酸痛程度增加(2.7 [IQR:2.0-3.0] vs. 2.3 [IQR: 2-3]; P < 0.001)、压力水平(平均得分 2.3 [IQR: 2.0-3.0] vs. 1.9 [IQR: 1.0-2.0]; P < 0.001)和知觉疲劳(平均得分 2.9 [IQR: 2.0-3.0] vs. 2.3 [IQR: 2.0-3.0]; P < 0.001)。同样,在睡眠质量较差的患者中,出现流感症状的球员比例增加了 4 倍多(4.1% vs. 17%;P < 0.001)。这项研究强调,良好的睡眠质量会对职业运动员的整体情绪和身体健康产生积极影响。我们的研究结果强调了有针对性的睡眠干预措施对于改善睡眠质量,进而优化心理和生理健康的重要性。

Engagement in physical activity (PA) benefits physical and mental health as well as many other areas of society. In Europe however, 1/3 adults do not meet minimum PA recommendations. Social value, and its quantification through social return on investment (SROI) evidence, may be a useful framing to enhance PA promotion. This study aimed to assess the current use of social value framing of PA in European Union (EU) policies.Content analysis of 45 EU member state policies which contain reference to PA was conducted to evaluate the presence of five social value domains and SROI evidence. Data was analysed using manual inductive coding, supported by DeepL translation and NVivo tools.Social value framing was present to a certain extent in existing policies, with improved health being the most commonly referenced benefit of PA, followed by reference to social and community and then environmental benefits. Acknowledgement of the positive impacts of PA on wellbeing and education was the least present. Reference to SROI evidence was also limited. Generally, policies lacked holistic recognition of the social value of PA. Policies from the health sector were particularly limited in recognising the wider benefits of PA, whilst those from the environmental sector acknowledged the widest range of co-benefits.Adopting social value framing could be a useful approach for enhancing PA promotion. Whilst it is present to a certain extent in existing policy, this could be increased in terms of comprehensiveness to increase issue salience and multisectoral policy action.
参与体育活动(PA)有益于身心健康以及社会的许多其他领域。然而,在欧洲,1/3 的成年人没有达到最低限度的 PA 建议。社会价值,以及通过社会投资回报(SROI)证据对其进行量化,可能是加强体育锻炼推广的有用框架。本研究旨在评估目前欧盟(EU)政策中 PA 社会价值框架的使用情况。研究人员对包含 PA 内容的 45 个欧盟成员国的政策进行了内容分析,以评估是否存在五个社会价值领域和 SROI 证据。在 DeepL 翻译和 NVivo 工具的支持下,采用人工归纳编码法对数据进行了分析。社会价值框架在一定程度上存在于现有政策中,改善健康是 PA 最常提及的益处,其次是社会和社区益处,然后是环境益处。PA 对福利和教育的积极影响最少。对 SROI 证据的引用也很有限。一般来说,政策缺乏对 PA 社会价值的整体认识。卫生部门的政策在承认 PA 的更广泛益处方面尤其有限,而环境部门的政策则承认了最广泛的共同益处。采用社会价值框架可能是加强 PA 推广的有用方法。虽然在现有政策中存在一定程度的社会价值框架,但仍可提高其全面性,以增加问题的显著性和多部门政策行动。

Overall physical activity (PA) has been linked to decreased olfactory dysfunction and could improve olfactory function. Additionally, decreased olfactory function can contribute to reduced overall PA levels, given its association with neurodegenerative disorders. This study aims to examine the relationship between specific PA parameters (duration, frequency, intensity) and olfactory function in adults.A total of 3,527 participants from the National Health and Nutrition Examination Survey (NHANES) 2013–2014 underwent assessments for weekly PA duration, frequency, and intensity, alongside a smell test (including odors such as chocolate, strawberry, grape, onion, smoke, natural gas, leather, and soap). Correlation analyses and binary logistic regressions using SPSS were used to evaluate associations.The total smell score exhibited small yet significant positive correlations with the duration, frequency, and volume of moderate PA (correlation coefficients ranging between 0.05 and 0.08; all p ≤ 0.05) and frequency of vigorous PA (correlation coefficient of 0.05; p < 0.05). For moderate PA, the duration, frequency, and volume were significantly and positively associated with the ability to correctly detect the smell of grapes while the frequency was significantly and positively associated with the ability to identify smoke and leather odors (odds ratios ranging from 1.01 to 1.07; p < 0.05). For vigorous PA, the frequency of PA was positively associated with the detection of grape smell (odds ratio of 1.05; p < 0.05).Some parameters of an active lifestyle are associated with improved odds of accurately identifying odors by up to 7.4%. Moderate PA duration, frequency, and volume were linked to better olfactory scores, while high-intensity PA had limited associations.
总体体力活动(PA)与嗅觉功能障碍的减少有关,并可改善嗅觉功能。此外,由于嗅觉功能与神经退行性疾病有关,因此嗅觉功能下降也会导致总体体力活动水平下降。这项研究的目的是研究成年人的特定活动量参数(持续时间、频率、强度)与嗅觉功能之间的关系。2013-2014 年美国国家健康与营养调查(NHANES)中共有 3527 名参与者接受了每周活动量持续时间、频率和强度的评估,同时还进行了嗅觉测试(包括巧克力、草莓、葡萄、洋葱、烟雾、天然气、皮革和肥皂等气味)。气味总分与中度 PA 的持续时间、频率和量(相关系数介于 0.05 和 0.08 之间;所有 p 均小于 0.05)以及剧烈 PA 的频率(相关系数为 0.05;p < 0.05)呈微小但显著的正相关。对于中度 PA,持续时间、频率和量与正确检测葡萄气味的能力呈显著正相关,而频率与识别烟味和皮革气味的能力呈显著正相关(几率比为 1.01 至 1.07;p < 0.05)。就剧烈运动而言,运动频率与检测葡萄气味呈正相关(几率比为 1.05;P < 0.05)。适度的体育锻炼持续时间、频率和运动量与更好的嗅觉评分有关,而高强度的体育锻炼则关系不大。

Intermittent fasting (IF) represents a dietary intervention similar to caloric restriction, characterized by the strategic limitation of food consumption. Among the diverse array of practices for IF, Ramadan IF (RIF), a religious observance in Islam, mandates that healthy adult Muslims abstain from both food and drinks during daylight hours. In sports, researchers have extensively studied IF effects on health, including sleep and physical performance, but its impact on cognitive functions during RIF remains understudied. Therefore, this study was conducted to evaluate the influence of RIF on psychomotor and cognitive performance among young female athletes.To achieve this purpose, a cohort of 23 female handball players, aged 17.2 ± 0.5 years, participated in a series of six testing sessions: one conducted prior to Ramadan (R0), and others during the first (R1), second (R2), third (R3), and fourth (R4) weeks of Ramadan, followed by a session in the week after Ramadan (R5). Each session involved assessments using a Simple Reaction Time Test (SRT), Choice Reaction Time Test (CRT), Vigilance Test (VT), and Mental Rotation Test (MRT). Additionally, dietary intake, body composition, and Pittsburgh Sleep Quality Index (PSQI) scores were evaluated during these periods.The obtained data illustrated that there was a decrease in SRT, CRT, VT, and MRT performances during R1 in comparison to R0 (all p < .001). This reduction was also observed in R2, R3, R4, and R5. Notably, during the fourth week of Ramadan (R4), these cognitive and psychomotor parameters were significantly lower than during the earlier weeks (R1, R2, R3; all p < .001). Furthermore, a gradual decrease in total PSQI scores, sleep quality, and sleep duration was observed throughout the Ramadan period, reaching the lowest levels during R4. These findings illustrate that RIF has a significantly detrimental impact on neuromuscular and cognitive abilities as well as sleep quality in young female athletes. The study also highlights a fluctuating pattern in cognitive function across the four weeks of Ramadan, with the most pronounced decline observed during the final week of fasting illustrating the importance of conducting similar studies on normal individuals from both genders with larger sample size.
间歇性禁食(IF)是一种类似于热量限制的饮食干预措施,其特点是有策略地限制食物摄入量。间歇性禁食的做法多种多样,其中斋月间歇性禁食(RIF)是伊斯兰教的一种宗教仪式,要求健康的成年穆斯林在白天禁食禁饮。在体育运动中,研究人员广泛研究了斋戒对健康的影响,包括睡眠和体能表现,但其对斋戒期间认知功能的影响仍未得到充分研究。为此,23 名年龄为 17.2±0.5 岁的手球女运动员参加了一系列共六次的测试:一次在斋月前(R0),其他测试分别在斋月的第一周(R1)、第二周(R2)、第三周(R3)和第四周(R4)进行,然后在斋月后一周(R5)进行。每次测试都使用简单反应时间测试 (SRT)、选择反应时间测试 (CRT)、警觉性测试 (VT) 和心理旋转测试 (MRT) 进行评估。获得的数据表明,与 R0 相比,SRT、CRT、VT 和 MRT 在 R1 阶段的表现有所下降(所有 p <.001)。在 R2、R3、R4 和 R5 中也观察到了这种下降。值得注意的是,在斋月的第四周(R4),这些认知和精神运动参数明显低于前几周(R1、R2、R3;所有 p <.001)。此外,在整个斋月期间,还观察到 PSQI 总分、睡眠质量和睡眠持续时间逐渐下降,在 R4 期间达到最低水平。这些研究结果表明,斋戒日对年轻女运动员的神经肌肉和认知能力以及睡眠质量有明显的不利影响。研究还强调了认知功能在斋月四周内的波动模式,在禁食的最后一周观察到最明显的下降,这说明对正常的男女个体进行样本量更大的类似研究的重要性。

The present study offers novel insight into the topic of experienced and observed emotional abuse by researching factors that affect athletes' responses to emotional abuse by coaches. The research aimed to explore three main questions: (1) whether athletic identity was associated with the prevalence of emotionally abusive coaching practices, and (2) disclosure of emotional abuse, and (3) whether demographic variations existed in the frequency of emotional abuse, athletic identity, and disclosure of the abuse. Study participants who filled in an anonymous digital survey consisted of athletes from elite to leisure levels living in Finland (N = 3687, aged 12–80, gender 61% female, 37.7% male, 0.8% other genders). The research findings highlighted three key insights. Firstly, Pearson correlations revealed that a salient athletic identity was related to a higher prevalence of emotional abuse. Secondly, ANOVA/Kruskal-Wallis tests between-groups indicated that particularly children were susceptible to the abuse. Thirdly, a mediation analysis showed that self-identity (aspect of athletic identity) influenced the relationship between experienced emotional abuse and disclosure, by reducing disclosure. As a result, holistic identity development is recommended for athletes and particularly children in sports.
本研究通过研究影响运动员对教练员情感虐待的反应的因素,对经历和观察到的情感虐待这一主题提出了新的见解。研究旨在探讨三个主要问题:(1) 运动员身份是否与教练情感虐待行为的发生率有关;(2) 情感虐待行为的披露;(3) 情感虐待行为的发生频率、运动员身份和虐待行为的披露是否存在人口统计学差异。参与匿名数字调查的研究人员包括居住在芬兰的从精英到休闲级别的运动员(N = 3687,年龄 12-80 岁,性别 61%为女性,37.7%为男性,0.8%为其他性别)。研究结果凸显了三个重要见解。首先,皮尔逊相关性表明,突出的运动员身份与较高的情感虐待发生率有关。其次,组间方差分析/Kruskal-Wallis 检验表明,儿童尤其容易受到虐待。第三,中介分析表明,自我认同(运动认同的一个方面)通过减少披露,影响了经历的情感虐待与披露之间的关系。因此,建议对运动员,尤其是运动儿童进行全面的身份发展。

As a result, holistic identity development is recommended for athletes and particularly children in sports.","PeriodicalId":509602,"journal":{"name":"Frontiers in Sports and Active Living","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141384640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Musculoskeletal (MSK) disorders represent a significant burden to society and can be unpleasant for the affected individuals. Physical activity (PA) can prevent MSK disorders while conferring other health benefits. The present study aimed to investigate associations between device-measured PA and perceived MSK disorders among young adult men.PA at different intensity levels, standing, and sedentary behavior were measured with a hip-worn accelerometer in a cohort of 422 young adult Finnish men aged 26 years on average. The incidences of three common MSK disorders (viz., knee pain, lumbar radicular pain, and lumbago pain) during the last month were inquired by a questionnaire. Binary logistic regression was used to examine the associations between the MSK outcomes and explanatory PA variables (PA times at different intensity levels, standing, and sedentary times). The models were controlled for age, education, smoking, BMI, and maximal oxygen uptake.PA, standing, and sedentary times were not significantly associated with the incidence of perceived MSK pain during the last month, except for lumbago pain. Lumbago pain was slightly more probable if the time spent in light PA increased, even after controlling for potential confounding factors, including moderate-to-vigorous PA, with an odds ratio (OR) of 1.07 (95% CI: 1.02–1.14). Sedentary time showed an opposite association, with an OR of 0.98 (95% CI: 0.96–1.00).There were neither positive nor negative clinically meaningful associations between PA and recent MSK disorders among young adult men. The result is surprising and requires further confirmation.
肌肉骨骼(MSK)疾病给社会带来沉重负担,也会给患者带来不愉快。体育锻炼(PA)可以预防 MSK 疾病,同时还能带来其他健康益处。本研究旨在调查设备测量的体力活动与年轻成年男性感知到的 MSK 疾病之间的关系。研究人员使用臀部佩戴的加速度计测量了 422 名平均年龄为 26 岁的芬兰年轻成年男性不同强度水平的体力活动、站立和久坐行为。此外,还通过问卷调查了最近一个月三种常见的MSK疾病(即膝关节疼痛、腰椎疼痛和腰痛)的发病率。采用二元逻辑回归法来检验 MSK 结果与解释性 PA 变量(不同强度的 PA 时间、站立和久坐时间)之间的关联。除腰痛外,PA、站立和久坐时间与上个月感觉到的 MSK 疼痛发生率无明显关联。即使在控制了包括中度至剧烈运动在内的潜在混杂因素后,如果轻度运动时间增加,腰痛的可能性也会略微增加,几率比(OR)为 1.07(95% CI:1.02-1.14)。久坐时间显示出相反的关联,OR 值为 0.98(95% CI:0.96-1.00)。这一结果令人惊讶,需要进一步证实。

Mandating headgear for field players in girls’ lacrosse to reduce head injuries, including concussion, has been heavily debated. However, research regarding the need and effectiveness of mandated headgear use in girls’ lacrosse is still developing. Therefore, this qualitative study aimed to identify the need for and barriers to the development of mandated headgear use policies in girls’ lacrosse in Ohio.We conducted six virtual focus groups, three with concussion experts (clinicians and researchers) and three with girls’ lacrosse stakeholders (high school players, parents, coaches, and officials). A focus group guide was developed to explore study participants’ perceptions and opinions on concussion in girls’ lacrosse, headgear use among players, and policies and policy development related to headgear use or a headgear mandate. We developed the codebook using an inductive and iterative approach based on focus group transcripts and used ATLAS.TI to code and analyze the transcript data.Concussion experts and stakeholders understood the potential consequences of concussion but did not perceive concussion as a pervasive problem in girls’ lacrosse. The prevention of head and facial injuries was regarded as a potential benefit of headgear use. However, stakeholders expressed that the myriad of arguments discussed opposing mandated headgear use including increased aggressive play and/or targeting, concerns over changes in the game, and cost strongly outweighed the benefits. Finally, both concussion experts and stakeholders identified multiple organizations, including USA Lacrosse, who could act as facilitators and/or barriers to developing, enacting, and implementing headgear policies.Concussion experts and stakeholders identified possible reasons for headgear use related to injury prevention but also identified several important barriers to the development of a headgear mandate for girls’ lacrosse in Ohio.
为减少包括脑震荡在内的头部伤害而强制要求女子曲棍球运动员佩戴头套的问题一直备受争议。然而,有关在女子曲棍球运动中强制使用头盔的必要性和有效性的研究仍在发展中。因此,本定性研究旨在确定在俄亥俄州女子长曲棍球运动中制定强制使用头盔政策的必要性和障碍。我们开展了六个虚拟焦点小组,其中三个有脑震荡专家(临床医生和研究人员)参与,三个有女子长曲棍球运动利益相关者(高中球员、家长、教练和官员)参与。我们制定了一份焦点小组指南,以探讨研究参与者对女子长曲棍球运动中的脑震荡、球员使用头盔以及与头盔使用或头盔强制规定相关的政策和政策制定的看法和意见。脑震荡专家和利益相关者了解脑震荡的潜在后果,但并不认为脑震荡是女子长曲棍球运动中普遍存在的问题。预防头部和面部受伤被认为是使用头套的潜在好处。然而,利益相关者表示,反对强制使用头盔的论点不胜枚举,包括增加侵略性比赛和/或攻击目标、对比赛变化的担忧以及成本等,这些都大大超过了使用头盔的益处。最后,脑震荡专家和利益相关者都指出,包括美国长曲棍球协会在内的多个组织可能会成为制定、颁布和实施头盔政策的促进因素和/或障碍。脑震荡专家和利益相关者指出了与预防伤害有关的使用头盔的可能原因,但也指出了俄亥俄州女子长曲棍球运动制定头盔规定的几个重要障碍。

It is widely acknowledged that coaches and physical education teachers play an important role in supporting holistic development in children and ensuring optimal performance in the training processes carried out to acquire fundamental movements and sport-specific basic skills. However, there is a need for further information on how both groups utilize and value different teaching methods during the training. The present study aims to examine the perceptions of coaches and physical education teachers regarding the use and value of teaching methods.The “Coaches’ Instructional Methods Utilization Scale” for coaches and the “Physical Education Teachers’ Perception of Teaching Methods Scale” for physical education teachers were administered to 114 coaches and 115 physical education teachers voluntarily participating from three randomly selected provinces of Türkiye. The Cronbach Alpha values ranged between .89 and .93 for the “Coaches’ Instructional Methods Utilization Scale” and between .90 and .96 for the “Physical Education Teachers’ Perception of Teaching Methods Scale”. Descriptive statistics were used in research, t-tests in binary comparisons, One-Way ANOVA in multiple comparisons, and Tukey's test in determining the source of differences.Similarities were observed in the most and least used methods by coaches and physical education teachers, as well as in their perceptions of the highest and lowest values for these methods. Additionally, coaches and physical education teachers exhibited similarities in their perceptions of value in terms of entertainment, learning, and motivation. It was observed that female physical education teachers had lower value perceptions among the levels of use of teaching methods and value perceptions according to gender. Comparing the usage levels and value perceptions of teaching methods by professional experience, significant differences were found in Exercise (B), Learner-Designed Individual Program (I), and Learner-initiated (J) methods for coaches, whereas no statistically significant difference was observed in value perceptions. Moreover, considering the physical education teachers, significant differences were found in Command (A), Self-Check (D), Guided Discovery (F), Problem-Solving: Single Solution (G) methods, and in value perceptions for the Exercise (B), Guided Discovery (F), Problem-Solving: Single Solution (G), Problem-Solving: Crating Different Paths (H), and Learner-initiated (J) values.
人们普遍认为,教练和体育教师在支持儿童的全面发展和确保儿童在训练过程中获得最佳表现以掌握基本动作和特定运动的基本技能方面发挥着重要作用。然而,我们需要进一步了解这两个群体在训练过程中如何利用和重视不同的教学方法。本研究旨在考察教练员和体育教师对教学方法的使用和价值的看法。研究人员对随机抽取的土尔其三个省的 114 名教练员和 115 名体育教师进行了 "教练员教学方法使用量表 "和 "体育教师对教学方法的看法量表 "的测试。教练员教学方法运用量表 "的 Cronbach Alpha 值介于 0.89 和 0.93 之间,"体育教师教学方法认知量表 "的 Cronbach Alpha 值介于 0.90 和 0.96 之间。在研究中使用了描述性统计,在二元比较中使用了 t 检验,在多元比较中使用了单向方差分析,在确定差异来源时使用了 Tukey 检验。此外,教练员和体育教师在娱乐、学习和激励方面的价值认识也有相似之处。据观察,在教学方法的使用水平和不同性别的价值认知中,女性体育教师的价值认知较低。比较不同专业经验的教学方法使用水平和价值认知,发现教练员在练习法(B)、学习者设计的个人项目(I)和学习者发起的教学方法(J)方面存在显著差异,而在价值认知方面则没有统计学意义上的显著差异。此外,就体育教师而言,在指挥法(A)、自我检查法(D)、引导发现法(F)、解决问题法(G)和单一解决方案法(H)方面存在显著差异:在价值感方面,练习(B)、引导发现(F)、解决问题:单一解决方案(G)的方法和价值感有明显差异:解决问题:单一解决方案(G)、解决问题:和 "学习者主动"(J) 的价值观。

Anterior cruciate ligament (ACL) injuries are common among physically active individuals, often requiring ACL reconstruction (ACLR) for recovery. Rehabilitating these injuries involves determining the appropriate timing for initiating open kinetic chain (OKC) exercises. Although OKC exercises are effective post-ACLR, their use in rehabilitation remains a subject of debate. Therefore, this study aims to conduct a systematic review to determine whether OKC or closed kinetic chain (CKC) exercises result in differences in laxity, strength of the knee extensor muscle group, function, and functional performance in ACL rehabilitation. Five electronic databases were searched for randomized controlled between-group trials (RCTs). Two reviewers independently evaluated the risk of bias using the PEDro scale. We performed a meta-analysis using a random-effects model or calculated mean differences (fixed-effect) where appropriate. Certainty of evidence was judged using the GRADE approach. The systematic literature search yielded 480 articles, of which 9 met the inclusion criteria. The evidence for all outcomes ranged from very low to low certainty. Across all comparisons, inconsistent results were found in outcome measures related to knee function between OKC and CKC exercises post-ACLR. A significant increase in quadriceps isokinetic strength was found in post-ACLR and ACL-deficient knees in favor of OKC exercises at 3 (p = 0.03) and 4 (p = 0.008) months, respectively. A significant decrease in knee laxity was observed in ACL-deficient knees in favor of OKC at 10 weeks (p = 0.01), although inconsistency was noted at 4 months. Finally, a significant decrease in pain was found in favor of early OKC compared to late OKC (p < 0.003). Additionally, in ACL-deficient knees, low load resistance training (LLRT) OKC showed no significant laxity difference compared to controls (p > 0.05). In contrast, high load resistance training (HLRT) OKC had less laxity than controls at 6 weeks (p = 0.02) but not at 12 weeks (p > 0.05). OKC exercises appear to be superior to CKC for improving quadriceps strength 3–4 months post-injury, whether as a part of conservative or post-surgery rehabilitation. On the other hand, OKC exercises seem to be either superior or equally effective to CKC for improving knee laxity, thus presenting their importance in being included in a rehabilitation protocol from the initial phase.PROSPERO [CRD42023475230].
前十字韧带(ACL)损伤在运动量大的人群中很常见,通常需要进行前十字韧带重建(ACLR)才能康复。这些损伤的康复需要确定开始开放运动链(OKC)锻炼的适当时机。虽然 OKC 运动在前交叉韧带重建术后很有效,但在康复中的应用仍存在争议。因此,本研究旨在开展一项系统性综述,以确定 OKC 或闭合动能链(CKC)运动是否会导致前交叉韧带康复中的松弛、膝关节伸肌肌群力量、功能和功能表现方面的差异。我们在五个电子数据库中搜索了随机对照组间试验(RCT)。两名审稿人使用 PEDro 量表独立评估了偏倚风险。我们酌情使用随机效应模型或计算平均差(固定效应)进行了荟萃分析。证据的确定性采用 GRADE 方法进行判断。系统性文献检索共获得 480 篇文章,其中 9 篇符合纳入标准。所有结果的证据确定性从很低到很低不等。在所有的比较中,发现 OKC 和 CKC 锻炼在 ACLR 后的膝关节功能相关结果测量中存在不一致的结果。在 3 个月(p = 0.03)和 4 个月(p = 0.008)时,发现 ACLR 术后膝关节和前交叉韧带缺损膝关节的股四头肌等速肌力明显增加,而 OKC 锻炼更有利。前交叉韧带缺损膝关节的膝关节松弛度在 10 周时有明显下降,而 OKC 运动更有利(p = 0.01),但在 4 个月时出现了不一致。最后,与晚期 OKC 相比,早期 OKC 的疼痛明显减轻(p 0.05)。相比之下,高负荷阻力训练(HLRT)的 OKC 在 6 周时的松弛程度低于对照组(p = 0.02),但在 12 周时则不尽相同(p > 0.05)。在改善受伤后 3-4 个月股四头肌力量方面,无论是作为保守康复还是手术后康复的一部分,OKC 运动似乎都优于 CKC 运动。另一方面,在改善膝关节松弛方面,OKC 训练似乎比 CKC 训练更有优势或同样有效,因此,从初始阶段就将其纳入康复方案具有重要意义。

Despite physical activity (PA) providing specific health benefits during pregnancy and the postpartum period, many women report decreased PA during this time. Provision of PA advice has been found to be lacking amongst midwives due to a range of barriers. This study aimed to evaluate United Kingdom's midwives' current role and knowledge regarding the provision of PA advice to pregnant and postpartum women and identify the barriers and potential solutions.Ten UK midwives (mean work experience ± SD: 15.5 years ± 10.2) participated in semi-structured interviews between May and July 2023. Data were analysed using a deductive thematic approach following Braun and Clarke's six steps. Demographic data were collected by Microsoft Forms then summarised using Microsoft Excel.Six themes with 25 subthemes were identified as barriers and solutions in delivering PA advice. The role of midwives in providing PA advice during pregnancy; the role of midwives in providing PA advice postpartum; intrinsic barriers that limit PA advice provision (confidence, safety concerns, knowledge, and midwife's personal body habitus); extrinsic barriers that limit PA advice provision (lack of time, education, PA not a priority in care); solutions to allow midwives to promote PA (including formal PA education, and dissemination of resources); and optimising delivery of PA advice (personalized approach, interprofessional collaboration, and linking to mental health benefits).Midwives consider themselves ideally placed to provide PA advice to pregnant women, with many aware of the benefits PA provides. Despite this, there is a lack of PA advice provision and knowledge of PA guidelines. Postpartum PA advice appeared to be considered outside the remit of midwives, due to limited contact. Further research is needed to determine the current level of PA advice provision for pregnant and postpartum women and explore the role of other healthcare professionals involved in maternity care.
尽管体育锻炼(PA)在孕期和产后对健康有特殊的益处,但许多妇女表示在此期间体育锻炼减少了。由于存在一系列障碍,助产士缺乏提供 PA 建议的能力。本研究旨在评估英国助产士目前在向孕妇和产后妇女提供 PA 建议方面的角色和知识,并找出障碍和潜在的解决方案。10 名英国助产士(平均工作经验± SD:15.5 年± 10.2)在 2023 年 5 月至 7 月期间参加了半结构化访谈。按照布劳恩和克拉克的六个步骤,采用演绎式主题方法对数据进行了分析。通过 Microsoft Forms 收集了人口统计学数据,然后使用 Microsoft Excel 进行了汇总。助产士在孕期提供 PA 建议的角色;助产士在产后提供 PA 建议的角色;限制提供 PA 建议的内在障碍(信心、安全顾虑、知识和助产士的个人身体习惯);限制提供 PA 建议的外在障碍(缺乏时间、教育、PA 不是护理中的优先事项);让助产士促进 PA 的解决方案(包括正规 PA 教育和资源传播);以及优化 PA 建议的提供(个性化方法、跨专业合作以及与心理健康益处挂钩)。助产士认为自己是向孕妇提供 PA 建议的理想人选,许多助产士都了解 PA 的益处。尽管如此,在提供 PA 建议和了解 PA 指南方面仍存在不足。由于接触有限,产后 PA 建议似乎被认为不属于助产士的职责范围。需要开展进一步的研究,以确定目前为孕妇和产后妇女提供 PA 建议的水平,并探讨参与产妇护理的其他医疗保健专业人员的作用。

This study aimed to evaluate United Kingdom's midwives' current role and knowledge regarding the provision of PA advice to pregnant and postpartum women and identify the barriers and potential solutions.Ten UK midwives (mean work experience ± SD: 15.5 years ± 10.2) participated in semi-structured interviews between May and July 2023. Data were analysed using a deductive thematic approach following Braun and Clarke's six steps. Demographic data were collected by Microsoft Forms then summarised using Microsoft Excel.Six themes with 25 subthemes were identified as barriers and solutions in delivering PA advice. The role of midwives in providing PA advice during pregnancy; the role of midwives in providing PA advice postpartum; intrinsic barriers that limit PA advice provision (confidence, safety concerns, knowledge, and midwife's personal body habitus); extrinsic barriers that limit PA advice provision (lack of time, education, PA not a priority in care); solutions to allow midwives to promote PA (including formal PA education, and dissemination of resources); and optimising delivery of PA advice (personalized approach, interprofessional collaboration, and linking to mental health benefits).Midwives consider themselves ideally placed to provide PA advice to pregnant women, with many aware of the benefits PA provides. Despite this, there is a lack of PA advice provision and knowledge of PA guidelines. Postpartum PA advice appeared to be considered outside the remit of midwives, due to limited contact. Further research is needed to determine the current level of PA advice provision for pregnant and postpartum women and explore the role of other healthcare professionals involved in maternity care.","PeriodicalId":509602,"journal":{"name":"Frontiers in Sports and Active Living","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141270052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
