Objective

To investigate differences in personality traits in female and male soccer players with or without primary anterior cruciate ligament reconstruction (ACLR) and between female and male players with ACLR.

Design

Cross-sectional.

Participants

188 female and 58 male players two years after ACLR and 119 female and 107 male knee-healthy players.

Main outcome measures

The Swedish universities Scales of Personality and the Sport Multidimensional Perfectionism Scale questionnaires.

Results

Females with ACLR did not differ from females without ACLR in any personality trait. Males with ACLR scored slightly higher than males without ACLR for stress susceptibility (50.9 ± 9.0 vs 47.8 ± 8.0) and lack of assertiveness (50.3 ± 8.9 vs 46.6 ± 9.4), and slightly lower in adventure seeking (51.9 ± 8.3 vs 55.1 ± 8.0), personal standards (3.3 ± 0.9 vs 3.7 ± 0.7), concern over mistakes (2.6 ± 0.9 vs 2.9 ± 0.8), and perceived coach pressure (2.0 ± 0.9 vs 2.4 ± 0.9) (p < 0.05, small‒medium effect sizes). Females with ACLR scored higher than males with ACLR for psychic anxiety and social desirability and lower for detachment, physical trait aggression and perceived parental and coach pressure (p < 0.05, small‒medium effect sizes).

Conclusion

Personality traits do not differ between females and small differences in males with or without ACLR. Sex differences exist in personality in soccer players, but the clinical importance is unclear.

目的：探讨原发性前交叉韧带重建术（ACLR）前后男女运动员及ACLR术后男女运动员人格特征的差异。设计:横断面。参与者：188名女性和58名男性球员在ACLR后两年，119名女性和107名男性球员膝盖健康。主要结果测量：瑞典大学人格量表和体育多维完美主义量表问卷。结果：ACLR女性与非ACLR女性在各人格特征上均无显著差异。患有ACLR的男性在应激敏感性（50.9±9.0比47.8±8.0）和缺乏自信（50.3±8.9比46.6±9.4）方面得分略高于未患有ACLR的男性，在寻求冒险（51.9±8.3比55.1±8.0）、个人标准（3.3±0.9比3.7±0.7）、对错误的担忧（2.6±0.9比2.9±0.8）和感知教练压力（2.0±0.9比2.4±0.9）方面得分略低于未患有ACLR的男性(p)。女性之间的人格特征没有差异，而患有或不患有ACLR的男性之间的差异很小。足球运动员的性格存在性别差异，但其临床重要性尚不清楚。

Objective in participants with Achilles tendinopathy. Additionally, it explored the relationships between muscle adaptations and functional outcomes.

Design

Prospective observational study.

Setting

Laboratory-based assessment.

Participants

Thirty-five participants with Achilles tendinopathy completed a 16-week exercise program.

Main outcome measures

Muscle EI of the medial (MG) and lateral gastrocnemius (LG) and soleus (SOL) was assessed using ImageJ. B-mode ultrasound was used to measure MG_CSA, LG_CSA, and SOL thickness at baseline and post-intervention. Functional outcomes included single-leg countermovement jump (CMJ), drop CMJ, and heel-rise (HR) endurance tests.

Results

MG_EI and LG_EI significantly decreased on both symptomatic sides (p < 0.05, d = 0.5–0.8). MG_CSA and LG_CSA increased (p < 0.05, d = 0.3), while SOL_EI and SOL thickness did not change (p > 0.05). Heel-rise work improved (p < 0.05, d = 0.4), but jump heights did not. Regression analysis showed that age, BMI, and muscle changes did not predict improvements in HR work (Adjusted R² = 0.11, p > 0.05).

Conclusions

The exercise program reduced muscle EI and increased hypertrophy but did not significantly improve calf endurance. Further research should explore how muscle adaptations affect function in Achilles tendinopathy rehabilitation.

Objective

To investigate the changes in shoulder functions with age, playing position, dominance and injury history in elite male rugby union players.

Design

Observational.

Setting

Sport setting.

Participants

162 players in U16, U18, U21 and professional squads.

Main outcome measures

Participant-reported outcome measures, maximal isometric internal and external rotation strength at glenohumeral joint, stability using Upper Quarter Y-Balance Test, power using Seated Single-Arm Horizontal Push Test (SSAHPT), and speed, power and resistance-to-fatigue using modified-Closed Kinetic Chain Upper Extremity Stability Test.

Results

The strength (η² = [0.24; 0.25]; p < 0.001) and power (η² = [0.36; 0.47]; p < 0.001) increased with increase in age, while stability and resistance-to-fatigue remained similar, and speed abilities decreased at professional level (η² = 0.10; p < 0.001). The forwards' shoulders were stronger (η² = [0.02; 0.14]; p = [<0.001; 0.02]) and more powerful (η² = 0.12; p < 0.001) than those of backs, while backs’ shoulders presented higher speed abilities (η² = 0.22; p < 0.001) and resistance-to-fatigue (η2 = 0.04; p = 0.02). No bilateral differences were found, except for SSAHPT, for which dominant side presented higher performance than nondominant one (η² = 0.12; p < 0.001). The injury history only affected the perceived functions (η² = [0.15; 0.18]; p < 0.001).

Conclusion

Understanding the progression of shoulder functions in male rugby union players is useful for designing injury prevention and performance enhancement programs from the academy to professional levels.

Introduction

Athletes who undergo anterior cruciate ligament (ACL) reconstruction may encounter subsequent graft rupture and revision. The current literature is limited to investigating the sports performance and reinjury rate after revision ACL. Whether a nonoperative approach achieves successful clinical outcomes after graft rupture has not yet been reported.

Case description

The patient was a 20-year-old male athlete who initially tore the left ACL when playing volleyball. By eight months after receiving ACL reconstruction and meniscal repair, the patient returned to the national collegiate tournament. However, the patient ruptured the graft 15 months postoperatively. Rehabilitation rather than a revision was elected, which focused on movement associated fear and volleyball-specific movements.

Outcomes

By 7 months after the second injury, the patient achieved >90 % symmetry in a battery of hop distance tests and shuttle run speed. The functional score on the Knee Outcome Survey Sports Activities Scale improved from 37/55 to 55/55. The psychological readiness improved from 56/120 to 117/120 on the ACL–Return to Sport after Injury scale. The patient then returned to full competition.

Conclusion

Personalized physical therapy may provide an option to promote return to sport after reinjuries. This case report illustrates the importance of addressing biopsychosocial factors in sport rehabilitation.

接受前交叉韧带（ACL）重建的运动员可能会遇到随后的移植物断裂和翻修。目前的文献仅限于研究前交叉韧带修复后的运动表现和再损伤率。移植物破裂后非手术入路是否取得成功的临床结果尚未报道。病例描述：患者是一名20岁的男性运动员，最初在打排球时撕裂左前交叉韧带。在接受前交叉韧带重建和半月板修复八个月后，患者回到了全国大学锦标赛。然而，患者在术后15个月导致移植物破裂。选择了康复而不是修订，重点是运动相关的恐惧和排球特定的运动。结果：第二次损伤后7个月，患者在一系列跳跃距离和穿梭跑速度测试中达到了90%的对称性。膝关节结局调查运动活动量表的功能评分从37/55提高到55/55。心理准备程度由56/120提高到117/120。然后病人恢复了完全的比赛。结论个性化的物理治疗可以促进再损伤后的运动恢复。本病例报告说明了在运动康复中解决生物心理社会因素的重要性。

Objective

To prospectively examine the association between pre-season low energy availability (LEA) risk and injury rates among female adolescents during the subsequent athletic season.

Design

Prospective cohort.

Setting

Academic research laboratory.

Participants

Adolescent female athletes ages 13–18 years.

Main outcome measures

The Low Energy Availability in Females Questionnaire (LEAF-Q) was completed at a pre-season evaluation including questions related to LEA-indicators (injury history, gastrointestinal symptoms, menstrual function). LEAF-Q scores ≥8 indicate high LEA risk. Participants then completed weekly surveys assessing subsequent injuries sustained throughout the 9-week athletic season. We calculated an injury rate ratio using Poisson regression with LEAF-Q scores <8 or ≥8 as the predictor, number of sport-related time-loss injuries as the outcome, adjusting for covariates.

Results

Fifty-nine participants completed the study (age = 15.9 ± 1.43). Twelve participants sustained 14 injuries during the season. Most injuries were musculoskeletal (93 %; N = 13). Those with LEAF-Q scores ≥8 had a higher injury rate per athletic exposure vs LEAF-Q scores <8 (rate ratio = 3.41; 95 % confidence interval: 1.12–11.4; p = 0.03).

Conclusion

Female adolescents at high LEA risk were more likely to sustain an injury than those at low LEA risk during a 9-week season. Pre-season LEA screening may identify individuals at risk for sustaining an in-season, sport-related injury.

目的探讨季前低能量可得性（LEA）风险与女性青少年随后运动季受伤率之间的关系。DesignProspective队列。学术研究实验室。参与者：13-18岁的青少年女运动员。主要结果测量在季前评估中完成女性低能量可用性问卷（LEAF-Q），包括与lea指标（损伤史、胃肠道症状、月经功能）相关的问题。LEAF-Q评分≥8分提示LEA风险高。然后参与者完成了每周的调查，评估在整个9周的运动赛季中持续的后续损伤。我们使用泊松回归计算损伤率比，以LEAF-Q得分<；8或≥8为预测因子，以运动相关的时间损失损伤数量为结果，并对协变量进行调整。结果59名参与者完成了研究（年龄= 15.9±1.43）。12名参与者在赛季中受伤14次。大多数损伤为肌肉骨骼（93%;N = 13）。LEAF-Q评分≥8的运动员每次运动暴露的受伤率高于LEAF-Q评分≥8的运动员（比率比= 3.41；95%可信区间：1.12-11.4;p = 0.03）。结论在为期9周的运动季中，高LEA风险的青少年女性比低LEA风险的青少年更容易发生损伤。赛季前的LEA筛查可以识别出有赛季中运动相关损伤风险的个体。

Objectives

To translate and cross-culturally adapt the Cutting Movement Assessment Score (CMAS) screening tool, and to preliminarily explore its reliability among Spanish-speaking football practitioners.

Design

Translation and cross-cultural adaptation (phase 1) and cross-sectional reliability study (phase 2).

Setting

Following international guidelines, three sports injury experts produced an initial Spanish adaptation of CMAS (CMAS-Sp). This version was then back-translated into English, and the translations were compared to produce a final version CMAS-Sp.

Participants

Twenty-one sports practitioners, including 11 novices (<1 year of experience) and 10 experts (>5 years of experience), assessed four 90° cutting actions with the CMAS-Sp.

Main outcome measures

Factor analysis, internal consistency, inter-rater reliability and agreement.

Results

Factor analysis suggested a single factor explaining 52.3 % of the variance. Internal consistency was acceptable (Cronbach's α = 0.70; McDonald's ω = 0.79). Reliability of the total score was excellent (ICC (2, k) [95 % CI] = 0.94, [0.82, 1.00]). Item-level percentage agreement ranged from 55 % to 89 % with Gwet's AC1 values ranging from moderate-to-almost perfect.

Conclusion

The CMAS-Sp demonstrated acceptable agreement and good reliability for assessing cutting mechanics in Spanish-speaking practitioners, showing promise as an accessible screening tool pending further validation.

目的对CMAS筛查工具进行翻译和跨文化适应，并初步探讨其在西班牙语足球从业人员中的可靠性。设计翻译和跨文化适应（第一阶段）和横断面可靠性研究（第二阶段）。根据国际指导方针，三位运动损伤专家制作了CMAS的初步西班牙版（CMAS- sp）。该版本随后被重新翻译成英文，并将翻译结果进行比较，从而产生最终版本CMAS-Sp。21名体育从业者，包括11名新手（1年经验）和10名专家（5年经验），用CMAS-Sp评估了4个90°切割动作。主要结果测量：因子分析、内部一致性、评分者间信度和一致性。结果单因素分析可解释52.3%的方差。内部一致性可接受（Cronbach's α = 0.70; McDonald's ω = 0.79）。总分的信度极好（ICC (2, k) [95% CI] = 0.94,[0.82, 1.00]）。项目级别的百分比一致性范围从55%到89%，Gwet的AC1值范围从中等到几乎完美。CMAS-Sp在评估西班牙语从业者的切削力学方面表现出可接受的一致性和良好的可靠性，有望成为一种可访问的筛选工具，有待进一步验证。

Objective

To examine differences in center of mass (COM) displacement and joint kinematics during the side hop test (SHT) between individuals with and without chronic ankle instability (CAI).

Design

Cross-sectional study.

Setting

Biomechanics laboratory.

Participants

Twelve healthy individuals (age: 19.8 ± 1.3 y; height: 162.6 ± 10.0 cm; weight: 57.1 ± 6.3 kg) and 12 with CAI (age: 20.0 ± 1.3 y; height: 162.4 ± 5.9 cm; weight: 55.7 ± 6.9 kg).

Main outcome measures

SHT completion time, COM displacement, and ankle, knee, and hip joint angles in sagittal, frontal, and transverse planes during SHT. Statistical parametric mapping visualized between-group differences.

Results

The CAI group demonstrated significantly longer SHT times than the control group (Mean Difference: 1.4 s, p < 0.001). Vertical COM displacement was significantly lower in the CAI group during 10–16 % (p = 0.03) and 55–70 % (p = 0.006) of the SHT cycle. Hip flexion angles were significantly greater in the CAI group during 17–20 % (p = 0.04) and 57–72 % (p = 0.004).

Conclusions

Compared with healthy individuals, those with CAI exhibited longer SHT times, likely due to a characteristic movement pattern involving increased COM lowering and greater hip flexion during the landing phase.

目的探讨慢性踝关节不稳定（CAI）患者和非慢性踝关节不稳定（CAI）患者侧跳试验（SHT）中质心（COM）位移和关节运动学的差异。DesignCross-sectional研究。SettingBiomechanics实验室。参与者健康12人（年龄19.8±1.3岁，身高162.6±10.0 cm，体重57.1±6.3 kg）， CAI患者12人（年龄20.0±1.3岁，身高162.4±5.9 cm，体重55.7±6.9 kg）。主要结果测量SHT完成时间、COM位移、SHT期间踝关节、膝关节和髋关节矢状面、额面和横切面角度。统计参数映射可视化组间差异。结果CAI组SHT时间明显长于对照组（平均差异为1.4 s, p < 0.001）。在SHT周期的10 - 16% （p = 0.03）和55 - 70% (p = 0.006)， CAI组的COM垂直位移明显降低。CAI组髋关节屈曲角度在17 - 20% （p = 0.04）和57 - 72% （p = 0.004）时显著增加。结论：与健康个体相比，CAI患者表现出更长的SHT时间，可能是由于在着陆阶段的特征性运动模式，包括增加的COM降低和更大的髋关节屈曲。

Objectives

To identify 12 forms from the traditional 108-form Tai Chi with the highest muscle activation values in the peroneus longus, peroneus brevis, and tibialis anterior and to design a Tai Chi training routine suitable for individuals with chronic ankle instability.

Design

Cross-sectional study.

Setting

Sports Biomechanics Laboratory.

Participants

Eight Tai Chi instructors were recruited, with data from six used for analysis.

Main outcome measures

The independent variable was the Tai Chi forms, while the dependent variable was the muscle activation measured using electromyography. The Vicon motion capture system recorded kinematic changes for form segmentation. Electromyography values from different segments were normalised to the maximum voluntary isometric contraction ratio for comparison.

Results

In the 12 Tai Chi forms, peroneus longus, peroneus brevis, and tibialis anterior exhibited muscle activation exceeding 55 %, 55 %, and 30 % of maximum voluntary isometric contraction in integrated electromyography, respectively, with root mean square reaching 116.9 %, 111.7 %, and 60.3 %. Adding transition stages expanded these into a 16-form routine, with no significant side differences.

Conclusions

The 16-form Tai Chi has the potential to enhance ankle stability by selectively training the muscles that counter ankle inversion. Randomised controlled trials are needed to assess its effectiveness in chronic ankle instability.

目的从传统的108型太极拳中找出腓长肌、腓短肌和胫骨前肌肌肉激活值最高的12种形式，设计适合慢性踝关节不稳患者的太极拳训练方案。DesignCross-sectional研究。运动生物力学实验室。研究招募了8位太极教练，其中6位的数据被用于分析。主要结果测量自变量为太极形式，而因变量为肌电图测量的肌肉激活。Vicon运动捕捉系统记录运动变化以进行形状分割。不同节段的肌电图值归一化为最大自主等距收缩比进行比较。结果12种太极形态中，腓骨长肌、腓骨短肌和胫骨前肌的肌肉激活分别超过最大自主等距收缩的55%、55%和30%，均方根分别达到116.9%、111.7%和60.3%。添加过渡阶段将这些扩展为16个形式的例程，没有显着的侧面差异。结论：16式太极拳通过选择性训练对抗踝关节内翻的肌肉，有可能提高踝关节的稳定性。需要随机对照试验来评估其对慢性踝关节不稳定的有效性。

Objectives

Following an anterior cruciate ligament (ACL) injury, athletes may become more reliant on their vision to maintain postural control. Wearing stroboscopic glasses, which intermittently disrupt visual input, can result in decreased vision. However, it remains unclear whether this affects single-leg hopping distance in athletes after ACL reconstruction (ACLR).

Design

Case-control study.

Setting

Sports physiotherapy clinics and sports clubs.

Participants

Athletes (Tegner-score >5) who were (mean (standard deviation)) 16.9 (4.6) months after ACLR (n = 17, age:24.7 (4.6) years), and uninjured matched controls (n = 17, age:26.1 (3.6) years).

Main outcome measures

Differences in jump distance (mean (95 % confidence intervals)) in the single-leg hop for distance (SLHD) test in normal and stroboscopic vision.

Results

Overall, the SLHD performance was significantly lower (p = 0.001) under stroboscopic vision 116 (95 % confidence interval (CI): 106,125) cm than under normal vision 125 (95 %CI: 116,135) cm. The difference in SLHD performance between the two vison conditions was significantly greater for the ACLR group (p = 0.003): for ACLR athletes, it was 125 (95 %CI: 115,135) cm to 111 (95 %CI: 99,122) cm, and for controls, it was 126 (95 %CI: 112,139) cm to 121 (95 %CI: 107,135) cm.

Conclusion

Stroboscopic vision significantly reduces SLHD outcomes. Greater reductions in hop performance were found in ACLR athletes compared to the control group under stroboscopic conditions. This suggests that the ACLR athletes rely more on visual input, which may be important to improve rehabilitation outcomes.

在前交叉韧带（ACL）损伤后，运动员可能会变得更加依赖于他们的视力来维持姿势控制。戴频闪眼镜会间歇性地干扰视觉输入，从而导致视力下降。然而，目前尚不清楚这是否会影响ACL重建（ACLR）后运动员的单腿跳跃距离。DesignCase-control研究。设置运动理疗诊所和运动俱乐部。参与者为运动员（Tegner-score >5），平均（标准差）为ACLR后16.9（4.6）个月（n = 17，年龄：24.7（4.6）岁）和未受伤的匹配对照组（n = 17，年龄：26.1（3.6）岁）。主要结果测量：正常视力和频闪视力的单腿跳距离（SLHD）测试中跳跃距离的差异（平均值（95%置信区间））。ResultsOverall, SLHD性能显著降低(p = 0.001)下频闪展望116(95%可信区间(CI): 106125)比在正常视觉125厘米(95%置信区间CI: 116135)厘米。SLHD性能之间的差异的两个条件也显著大于幻影ACLR组(p = 0.003): ACLR运动员,那是125年(95%置信区间CI: 115135)厘米到111(95%置信区间CI: 99122)厘米,和控制,这是126年(95%置信区间CI: 112139)厘米到121(95%置信区间CI:结论频闪视觉可显著降低SLHD的预后。在频闪条件下，与对照组相比，ACLR运动员的跳跃性能下降幅度更大。这表明ACLR运动员更多地依赖视觉输入，这可能对改善康复结果很重要。

Objective

Examine whether runners with specific diseases, including osteoarthritis, osteoporosis, rheumatoid arthritis, diabetes, multiple sclerosis (MS), cancer, or multiple diseases, sustain more running-related injuries (RRI) compared with healthy runners in the Garmin-RUNSAFE Running Health Study.

Design

18-month cohort study.

Setting/participants

Participants were runners ≥18 years, proficient in English, and using a Garmin watch. Exposure included having one of the following diseases: osteoarthritis, osteoporosis, rheumatoid arthritis, diabetes type 1 or 2, multiple sclerosis (MS), cancer, or multiple diseases.

Main outcome measures

Outcome was sustaining an RRI and was reported through weekly questionnaires. Appropriate censoring methods were applied for discontinued participation. Time-to-event analysis assessed after 1000 km running.

Results

Of 7038 included runners, 6207 had no disease and 831 had at least one of the specified diseases. After 1000 km, 64.4 % of runners with a disease and 56.7 % of healthy runners sustained an RRI, yielding a cumulative incidence risk difference (cIRD) of 8.0 % (95 %CI: 4.0–12.0 %). Among separate diseases, a significant risk difference was observed between the osteoarthritis group and the healthy group, with a cIRD of 14.7 % (95 %CI: 9.0–20.4 %).

Conclusions

A significantly higher incidence of running-related injuries was observed among adult runners reporting a disease. Runners with osteoarthritis is a particularly vulnerable sub-group.

目的在Garmin-RUNSAFE跑步健康研究中，研究患有特定疾病（包括骨关节炎、骨质疏松症、类风湿关节炎、糖尿病、多发性硬化症（MS）、癌症或多种疾病）的跑步者是否比健康的跑步者遭受更多的跑步相关损伤（RRI）。设计18个月队列研究。设定/参与者：参与者为18岁以上、英语熟练、佩戴Garmin手表的跑步者。暴露包括患有以下疾病之一：骨关节炎、骨质疏松症、类风湿性关节炎、1型或2型糖尿病、多发性硬化症（MS）、癌症或多种疾病。主要结果测量结果是维持RRI，并通过每周问卷报告。对停止参加的活动采用适当的审查方法。在1000公里的跑步后评估时间到事件的分析。结果7038名跑步者中，6207名没有疾病，831名至少患有一种指定疾病。1000公里后，64.4%的患病跑步者和56.7%的健康跑步者持续RRI，累积发病率风险差（cIRD）为8.0% （95% CI: 4.0 - 12.0%）。在单独的疾病中，骨关节炎组和健康组之间观察到显著的风险差异，cIRD为14.7% （95% CI: 9.0 - 20.4%）。结论在报告疾病的成年跑步者中，与跑步相关的伤害发生率明显较高。患有骨关节炎的跑步者是一个特别脆弱的亚群体。
