Background

Knee stiffness is a common complaint experienced during prolonged periods of sedentary behaviour, including following prolonged sitting, in both healthy and people with musculoskeletal conditions. Reduction of self-reported knee stiffness is important to patient-centred outcomes. Our aim was to obtain pilot data to determine the timeframe for knee stiffness onset in healthy populations.

Methods

Forty-two participants (20–76 years) with no diagnosed chronic musculoskeletal condition were recruited. After pilot testing, perceived knee joint stiffness and pain (Visual Analogue Scale) were measured while sitting (at 15, 30, 60, and 90 min) with the knee joint held at 90°. Correlations between knee stiffness after 90 min of sitting and baseline demographic data, and knee range of motion were analysed.

Results

Greater levels of self-reported stiffness were observed (mean ± SD) after sitting still for 30 (1.8 ± 1.6; p < 0.001), 60 (3.4 ± 2.4; p < 0.001) and 90 min (4.1 ± 2.6; p < 0.001) compared to baseline (n = 31). Increase of self-reported pain occurred by 60 and 90 min of sitting (p < 0.001). Minimal clinical important difference (MCID) (±2 cm) in stiffness occurred by 60 min of sitting (+2.6 cm) with pain not reaching MCID by 90 min. Self-reported stiffness at 90 min of sitting was negatively correlated with participant age (r = −0.433, p = 0.004).

Conclusions

Healthy adults begin to experience knee stiffness when sitting still after 30 min, though this was only clinically relevant by 60 min. Moving the joint, even whilst still sitting, helped to alleviate joint stiffness and pain, which may assist in providing advice to all adults on sedentary behaviours.

背景：无论是健康人还是患有肌肉骨骼疾病的人，在长时间的久坐行为（包括久坐）中，膝关节僵硬都是一种常见的症状。减少自我报告的膝关节僵硬对以患者为中心的结果很重要。我们的目的是获得试点数据，以确定健康人群中膝关节僵硬发作的时间框架。方法招募42名未确诊慢性肌肉骨骼疾病的参与者（20-76岁）。在初步测试后，当膝关节保持90°坐姿（15、30、60和90分钟）时，测量感知到的膝关节僵硬度和疼痛（视觉模拟量表）。分析坐下90分钟后膝关节僵硬度与基线人口统计学数据和膝关节活动范围之间的相关性。结果静坐30分钟（1.8±1.6;p < 0.001）、60分钟（3.4±2.4;p < 0.001）和90分钟（4.1±2.6;p < 0.001）后，与基线（n = 31）相比，自我报告的僵硬程度（mean±SD）更高。自我报告的疼痛在静坐60分钟和90分钟时增加（p < 0.001）。静坐60分钟（+2.6 cm）时僵硬度的最小临床重要差异（MCID）（±2 cm），疼痛在90分钟时未达到MCID。自我报告的90分钟坐姿僵硬度与参与者年龄呈负相关（r = - 0.433, p = 0.004）。结论：健康的成年人在静坐30分钟后开始出现膝关节僵硬，但在静坐60分钟后才有临床意义。即使在坐着的时候活动关节，也有助于减轻关节僵硬和疼痛，这可能有助于为所有久坐行为的成年人提供建议。

Objectives

The long-term effects of infant weight gain and motor development on adiposity and physical activity remain unclear. This study investigates how these factors predict objectively assessed adiposity and physical activity at early school age, and whether these associations persist into preadolescence.

Methods

This retrospective study with prospective follow-up included 223 first-grade children (aged 6–7) for initial assessments, including body fat percentage determined by dual-energy X-ray absorptiometry and moderate-to-vigorous physical activity (MVPA) assessed using an accelerometer. A four-year follow-up involved 216 fifth-grade children (aged 10–11). Data on weights measured at birth and at 1-, 3–4-, and 18-month checkups, along with ages at which six gross motor milestones were achieved, were extracted from the Maternal and Child Health Handbook.

Results

Multivariable regression analyses, adjusted for sex, gestational age, height, school location, maternal age, and pre-pregnancy body mass index showed that rapid weight gain from birth to 18 months (p = 0.01) and later age at standing with support (p < 0.001) were independently associated with higher body fat assessed in the first grade, with a significant negative interaction (p = 0.02). Later age at standing with support was also significantly associated with less MVPA time in the first grade (p = 0.02). Among these, only the association between age at standing with support and body fat remained significant in the fifth grade (p < 0.01).

Conclusions

This study highlights the long-term implications of later achievement of motor milestones for future adiposity, persisting into preadolescence. Infant motor development can be an important determinant of future health.

目的：婴儿体重增加和运动发育对肥胖和体力活动的长期影响尚不清楚。本研究调查了这些因素如何客观地预测学龄期早期的肥胖和体育活动，以及这些关联是否会持续到青春期前。方法回顾性前瞻性随访研究纳入223名一年级儿童（6-7岁）进行初步评估，包括用双能x线吸收仪测定体脂率，用加速度计评估中高强度体力活动（MVPA）。为期四年的随访涉及216名五年级儿童（10-11岁）。出生时以及1个月、3-4个月和18个月检查时测量的体重数据，以及达到6个大肌肉运动里程碑的年龄，均取自《妇幼保健手册》。结果经性别、胎龄、身高、学校位置、母亲年龄和孕前体重指数调整后的多变量回归分析显示，从出生到18个月体重快速增加（p = 0.01）和较晚的站立年龄（p < 0.001）与一年级时评估的较高体脂独立相关，并存在显著的负交互作用（p = 0.02）。支持站立年龄越晚，一年级的MVPA时间越短（p = 0.02）。其中，只有支撑站立年龄与体脂之间的相关性在五年级仍然显著（p < 0.01）。结论：这项研究强调了运动里程碑的后期实现对未来肥胖的长期影响，并持续到青春期前。婴儿运动发育是未来健康的重要决定因素。

Background

People with disability participate in sport and exercise at lower rates than the general population. Health and fitness professionals’ lack of knowledge regarding the support needs of people with disability has been identified as a major barrier to participation. To address this barrier, we developed a support needs assessment tool for people with disability wanting to participate in sport and exercise. The present study explored the usability and acceptability of the tool from the perspectives of the end-users.

Method

An online survey was used to gather data on the usability and acceptability of the tool from the perspectives of people with disability, health professionals, community-based fitness professionals, and relevant researchers.

Results

A total of 52 people completed the survey. Participants reported that the SNAT-SE was a useful and acceptable tool to assess the support needs of people with disability wanting to participate in sport and exercise. Participants also provided recommendations on refinements to further enhance the use of the tool. Refinements included increased clarity of the language used throughout the tool, a reduction in the overall length and flexibility in administration to reduce the time burden, and modifications to ensure all disability populations could equally benefit from the tool.

Conclusion

Overall, the tool showed good usability and acceptability. Further research is required to evaluate the tool's effectiveness in improving the confidence and quality of service delivery of health and fitness professionals supporting people with disability to participate in sport and exercise.

残疾人参加体育运动和锻炼的比例低于一般人群。保健和健身专业人员对残疾人的支助需求缺乏了解已被确定为参与的主要障碍。为了解决这一障碍，我们开发了一种支持需求评估工具，用于希望参加体育运动和锻炼的残疾人。本研究从最终用户的角度探讨了该工具的可用性和可接受性。方法采用在线调查的方式，从残疾人、卫生专业人员、社区健身专业人员和相关研究人员的角度收集工具的可用性和可接受性数据。结果共有52人完成了调查。与会者报告说，SNAT-SE是一个有用和可接受的工具，用于评估希望参加体育和锻炼的残疾人的支持需求。与会者还提出了改进建议，以进一步加强该工具的使用。改进包括提高整个工具所用语言的清晰度，减少总体长度和管理灵活性以减少时间负担，并进行修改以确保所有残疾人都能从该工具中平等受益。结论总体而言，该工具具有良好的可用性和可接受性。需要进一步研究以评估该工具在提高保健和健身专业人员支持残疾人参加运动和锻炼的信心和服务质量方面的有效性。

Background

Learning to swim is recommended as an important layer of protection in drowning prevention. However, identifying what aquatic skill(s) are essential, and the absence of a gold or industry standard makes establishing the reliability of learn to swim assessment difficult.

Methods

Five aquatic skills aligned with water safety and survival, from the Australian Water Safety Council's 2016 benchmark, were included in a cross-sectional study designed to test the reliability of two assessment tools: 1. competent/not yet competent and 2. RAEE (Refuse, Assisted, Effective, Efficient) assessment tool. Twelve participants (raters) from a single Gold Level AUSTSWIM recognised swim centre completed the assessment across three sessions and inter- (weighted kappa) and intra-rater (Chi squares) reliability was calculated.

Results

There was limited/poor inter and intra rater reliability for both assessment methods and this increased across sessions for three of the five chosen skills (crouch dive, sidestroke and compact jump). RAEE assessment tool demonstrated lower inter- and intra-rater reliability (poor to fair) when compared to use of the C/NYC assessment method (fair to moderate) across five water safety skills.

Conclusion

Regardless of the assessment approach taken, both inter and intra – rater reliability was limited when assessing water safety skills. A lack of consensus was found relating to proficiency in performance and raters lacked a clear understanding of the complexities involved in assessment, including an established foundation of what proficient motor skills performance looks like.

学习游泳是预防溺水的重要保护措施。然而，确定哪些水上技能是必不可少的，以及缺乏黄金标准或行业标准，使得建立学习游泳评估的可靠性变得困难。方法将澳大利亚水安全委员会2016年基准中与水安全和生存相关的五项水生技能纳入一项横断面研究，旨在测试两种评估工具的可靠性：2.胜任/不胜任；RAEE（拒绝、辅助、有效、高效）评估工具。12名参与者（评分者）来自一个Gold Level AUSTSWIM认可的游泳中心，完成了三个阶段的评估，并计算了评分者之间（加权kappa）和内部（卡方）的信度。结果两种评估方法的内部和内部可靠性都有限/很差，并且在五个选择的技能中的三个（蹲伏跳水，侧身和紧凑型跳跃）中，这种情况在不同的课程中有所增加。与使用C/NYC评估方法（公平到中等）相比，RAEE评估工具在五种水安全技能中显示出较低的等级间和等级内可靠性（差到公平）。结论无论采用何种评价方法，在评价水安全技能时，评价对象间和评价对象内的信度都是有限的。研究发现，在表现熟练程度方面缺乏共识，评分者对评估的复杂性缺乏清晰的理解，包括对熟练运动技能表现的既定基础。

Objectives

Australia’s bid for the 2032 Paralympic Games included a commitment to increasing sport participation among people with disabilities by 500,000. Realising this legacy will require an accurate understanding of the composition of the Australian disability population – age, sex, disability type and disability severity – as well as current Para sport participation rates.

Design and methods

Collation and synthesis of publicly available data from the Australian Bureau of Statistics, the Australian Institute of Health and Welfare and Para sport master lists.

Results

Among 4.37M Australians with disability, 44.5 % were aged ≥65 yrs. Of those aged <65 yrs, the maximum population that could be eligible for Para sport comprise 529,800 with intellectual disability, 85,900 with sight loss, and 802,000 with physical disability. Many high-prevalence disability types are not eligible for Para sport (e.g., hearing loss = 1.07M; psychosocial disability = 1.14M) and sport may not be appropriate for other types (e.g., chronic pain/discomfort = 1.46M). Compared with others with disability, those with severe/profound disabilities are least active (17.4 % meet physical activity guidelines) and underrepresented in sport (3.2 % of Para athletes with physical impairment have high support needs).

Conclusions

Increasing participation in any form of physical activity – including Para sports and other sports – by 500,000 would be a more achievable and inclusive legacy goal than increasing sports participation alone. Such an approach would cater for high-prevalence disability groups for whom commencement of competitive sport may not be suitable (e.g., >65 yrs, chronic pain). To permit safe, effective engagement in sport/physical activity for individuals with severe impairments and high support needs, investment in development and implementation of specialised, evidence-based programs is required.

澳大利亚申办2032年残奥会时，承诺将残疾人参与体育运动的人数增加50万。要实现这一遗产，需要准确了解澳大利亚残疾人口的构成——年龄、性别、残疾类型和残疾严重程度——以及目前残疾人运动的参与率。设计和方法整理和综合来自澳大利亚统计局、澳大利亚卫生和福利研究所和残疾人运动总名单的公开数据。结果437万澳大利亚残疾人中，年龄≥65岁的占44.5%。在65岁的老年人中，有资格参加残疾人运动的最大人数包括529,800名智障人士、85,900名视力丧失人士和80.2万名身体残疾人士。许多高患病率残疾类型不符合残疾人运动资格(例如，听力损失= 1.07M；心理残疾= 1.14M)，运动可能不适合其他类型（例如，慢性疼痛/不适= 1.46M）。与其他残障人士相比，重度/重度残障人士活动最少（17.4%符合身体活动指南），在体育运动中的代表性不足（3.2%的残障残疾人运动员有很高的支持需求）。增加50万人参加任何形式的体育活动——包括残疾人运动和其他运动——比仅仅增加体育参与更容易实现，更具有包容性。这种方法将满足高患病率的残疾群体，他们可能不适合开始竞技体育（例如，65岁，慢性疼痛）。为了让严重残疾和高支持需求的个人安全、有效地参与体育/身体活动，需要投资开发和实施专门的、以证据为基础的项目。

The return-to-play process is multifactorial, requiring input from multiple disciplines for rehabilitation. This pilot study used a prospective interdisciplinary approach to assess male professional Rugby Union players' (n = 7) rehabilitation following a non-contact lower-limb injury. Kinetic and self-efficacy assessments were conducted across three rehabilitation phases (acute, middle, late). Biomechanical changes (p < 0.05) were observed across all phases; alongside self-efficacy increases. Moderate-to-strong positive relationships (r = 0.77–0.80) were found between kinetic and self-efficacy changes. Practitioners should incorporate both measures throughout rehabilitation, as each offers distinct insights into recovery despite their high correlation. An interdisciplinary approach ensures a comprehensive assessment, enhancing players’ rehabilitation outcomes.

恢复比赛的过程是多因素的，需要来自多个学科的康复投入。本初步研究采用前瞻性跨学科方法评估橄榄球联盟男性职业球员（n = 7）在非接触性下肢损伤后的康复情况。动力学和自我效能评估在三个康复阶段（急性、中期、晚期）进行。生物力学变化(p <；各期均观察到0.05)；同时，自我效能也在增加。动力与自我效能之间存在中强正相关关系（r = 0.77 ~ 0.80）。从业者应该在整个康复过程中结合这两种措施，因为尽管它们高度相关，但每种措施都提供了不同的康复见解。跨学科的方法确保了全面的评估，提高了球员的康复效果。

Coaching professional sport is stressful, yet there is little information detailing the physiological and psychological responses of coaches during match-play. This case report examined physiological and psychological alterations when coaching professional Australian Rules football. One experienced head coach was monitored for heart rate, stress-related hormones and psychological stress before, during and after seven matches. Heart rate fluctuated during match-play, with locomotion during match breaks contributing to elevated values. Stress hormones did not change, while the psychological questionnaire revealed differences in perceptions of accomplishment, success, recovery and stress related to match outcome. This case report indicated substantial elevations in heart rate while coaching professional football and furthermore, differences in psychological outcomes from winning or losing suggests the need to develop contextualised recovery and coping strategies. With coaching eliciting alterations to physical and psychological markers in this case, confirmatory research with larger cohorts should examine cardiovascular health and well-being strategies in coaches.

指导职业运动是有压力的，但很少有信息详细说明教练在比赛中的生理和心理反应。本案例报告研究了职业澳式足球教练的生理和心理变化。一位经验丰富的主教练在七场比赛之前、期间和之后接受了心率、压力相关激素和心理压力的监测。在比赛中心率波动，比赛休息时的运动导致心率升高。压力荷尔蒙没有变化，而心理问卷显示了与比赛结果相关的成就、成功、恢复和压力的感知差异。该案例报告表明，在执教职业足球时，心率会显著升高，此外，输赢后心理结果的差异表明，需要制定情境化的恢复和应对策略。在这种情况下，由于教练会引起身体和心理指标的改变，因此应该对教练的心血管健康和福祉策略进行更大规模的验证性研究。

Background

The Orchard Sports Injury and Illness Classification System (OSIICS) requires regular update to; stay relevant to changes required for optimal code recording; to add additional language translations as they become available and add female-specific codes to reflect contemporary clinical diagnosis and the increase in women's sport participation.

Methods

Codes were added to the existing version 15 after the assembly of an ad hoc panel of co-authors. Being a revision that only added codes without changing any structure, informal methodology, primarily conducted by email discussion amongst the author group, was used to resolve issues. Two authors who were native Italian and Spanish speakers, and fluent in English were used to create the respective language translations.

Results

The area of greatest deficiency for OSIICS versions 13–15 was in coding for breast conditions. To fit in with the existing consensus categories, the injury format used was CxBxx with a third character B to signify breast within the chest region. For breast illness/medical disorders, the coding format was MxxBx

Conclusion

Although consideration was given to creating a new, standalone category for breast injuries, due to the formalised alignment between OSIICS and Sports Medicine Diagnostic Coding System it was decided such a change requires the IOC consensus panel to re-convene. Additionally, the medical/illness categories need consideration of whether breast disorders best fit in the endocrine or genitourinary system, or if an expanded medical category is needed for female reproductive medical conditions.

果园运动损伤和疾病分类系统（OSIICS）需要定期更新；保持与最佳代码记录所需的更改相关；增加可用的其他语言翻译，并增加女性特定代码，以反映当代临床诊断和妇女参与体育运动的增加。在由共同作者组成的特别小组集会之后，将MethodsCodes添加到现有的版本15中。作为一个只增加代码而不改变任何结构的修订，非正式的方法主要是通过作者组之间的电子邮件讨论来解决问题。两位母语分别是意大利语和西班牙语的作者，并精通英语，他们被用来创建各自的语言翻译。结果OSIICS版本13-15最大的缺陷是对乳腺状况的编码。为了符合现有的共识分类，使用的损伤格式为CxBxx，其中第三个字符B表示胸部区域内的乳房。尽管考虑为乳房损伤创建一个新的独立类别，但由于OSIICS和运动医学诊断编码系统之间的正式一致性，决定这样的改变需要IOC共识小组重新召开会议。此外，医疗/疾病类别需要考虑乳腺疾病是否最适合内分泌或泌尿生殖系统，或者是否需要扩大女性生殖医疗条件的医疗类别。

Background

Voluntary activation is a measure of neural drive, typically measured during maximal contractions, and provides insight into motor function. This systematic review examined voluntary activation assessment of the ankle plantar flexors in healthy and pathological populations, and the association of participant age and positioning (knee and ankle joint angles) with voluntary activation level.

Methods

A systematic review and meta-analyses were conducted. Six electronic databases were systematically searched for studies that assessed voluntary activation of the ankle plantar flexors using the interpolated twitch technique or the central activation ratio. Meta-analyses were performed using an inverse variance, random-effects maximal likelihood model of continuous outcomes within SPSS Statistics, and subsequent meta-regression performed for age, knee angle and ankle angle. Methodological quality was assessed using the Analytical Cross-Sectional Studies Checklist from the Joanna Briggs Institute.

Results

A total of 74 studies were included, 5 included participants with pathological conditions (2 Achilles tendinopathy and 3 stroke) and 69 included only healthy participants. The meta-analysis demonstrated plantar flexion voluntary activation levels for healthy populations of 91 %, 90 % for Achilles tendinopathy and 35 % for stroke. Older age was associated with lower voluntary activation (β = −0.072; p = 0.035) and greater knee flexion angle was associated with higher voluntary activation (β = −0.033; p = 0.045). No association of voluntary activation and ankle position was demonstrated (β = −0.070, p = 0.488). Majority of the included studies were judged to have low methodological quality (97 %).

Conclusions

Voluntary activation was comparable between healthy participants and Achilles tendinopathy, and significantly lower in people following stroke. Age and knee joint position but not ankle joint position was associated with the level of plantar flexor voluntary activation.

自愿激活是一种神经驱动的测量，通常在最大收缩时测量，并提供对运动功能的洞察。本系统综述检查了健康和病理人群踝关节底屈肌的自主激活评估，以及参与者年龄和体位（膝关节和踝关节角度）与自主激活水平的关系。方法进行系统评价和荟萃分析。系统地检索了六个电子数据库，以评估使用内插抽动技术或中枢激活比的踝关节足底屈肌的自主激活。meta分析采用SPSS统计中连续结果的逆方差、随机效应最大似然模型进行，随后对年龄、膝关节角度和踝关节角度进行meta回归。方法质量采用乔安娜布里格斯研究所的分析横断面研究检查表进行评估。结果共纳入74项研究，5项研究纳入病理状态（2例跟腱病和3例卒中），69项研究仅纳入健康受试者。荟萃分析显示，健康人群的足底屈曲自发激活水平为91%，跟腱病患者为90%，中风患者为35%。年龄越大，自愿性活动越低（β = - 0.072; p = 0.035），膝关节屈曲角度越大，自愿性活动越高（β = - 0.033; p = 0.045）。自主活动与踝关节位置无关联（β = - 0.070, p = 0.488）。大多数纳入的研究被认为方法学质量较低（97%）。结论：自愿激活在健康参与者和跟腱病患者之间具有可比性，而在中风患者中明显较低。年龄和膝关节位置与足底屈肌自主激活水平相关，但踝关节位置与足底屈肌自主激活水平无关。
