Anterior cruciate ligament (ACL) injury and reconstructive surgery is known to cause long‐term negative impacts on quadriceps muscle size. With the known link between reduced muscle size and the health and functioning of the knee joint, it is important rehabilitation programs aim to restore quadriceps mass as safely and quickly as possible. However, a comprehensive review of interventions investigating the impact of training interventions on quadriceps muscle size in ACL‐reconstructed individuals has yet to be undertaken. Therefore, this article systematically reviews the evidence investigating training interventions that aim to improve quadriceps size in ACL‐reconstructed individuals. A literature search was performed in MEDLINE, SPORTDiscus, CINAHL, and Web of Science. Observational and experimental studies investigating training interventions impact on quadriceps muscle size in ACL‐reconstructed individuals were included. Risk‐of‐bias assessment (Downs and Black) was completed on included studies, data was extracted, and a best evidence synthesis was undertaken. 718 articles were returned in the initial search; following screening, six articles were included in this review. Results from the best evidence synthesis suggest there is moderate evidence for eccentrically biased training to increase quadriceps size. Both traditional resistance training and blood flow restriction training showed conflicting results for improving quadriceps size. However, the results for traditional resistance training and blood flow restriction training may have been limited by differing imaging methods across included studies. This review highlights the positive changes in quadriceps size seen following traditional, eccentrically biased and blood flow restriction exercise interventions in ACL‐reconstructed limbs, despite the limited number of studies. Further work is needed to identify and optimize the best practice for hypertrophic training in these individuals.
众所周知，前交叉韧带(ACL)损伤和重建手术会对股四头肌的大小产生长期的负面影响。众所周知，肌肉大小的减少与膝关节的健康和功能之间存在联系，因此，旨在安全、快速地恢复股四头肌质量的康复计划非常重要。然而，对前交叉韧带重建患者进行训练干预对股四头肌大小影响的综合评估尚未开展。因此，本文系统地回顾了旨在改善ACL重建患者股四头肌大小的训练干预的证据。在MEDLINE、SPORTDiscus、CINAHL和Web of Science中进行文献检索。观察性和实验性研究调查了训练干预对前交叉韧带重建个体股四头肌大小的影响。对纳入的研究完成了偏倚风险评估(Downs和Black)，提取了数据，并进行了最佳证据合成。在最初的搜索中返回了718篇文章;经过筛选，本综述纳入了6篇文章。最佳证据综合的结果表明，有中度证据表明偏心训练可以增加股四头肌的大小。传统的阻力训练和血流限制训练在改善股四头肌大小方面显示出相互矛盾的结果。然而，传统阻力训练和血流限制训练的结果可能受到纳入研究中不同成像方法的限制。尽管研究数量有限，但这篇综述强调了在ACL重建肢体中，传统的、偏心的和血流限制运动干预后，股四头肌大小的积极变化。需要进一步的工作来确定和优化这些个体的肥厚训练的最佳实践。

The objective of this study was to examine the effect of a neuromuscular training (NMT) warm‐up on the prevalence of overuse lower extremity (LE) injuries in children's football. Twenty Finnish U11‐U14 youth football clubs (n = 1409 players; females 280, males 1129; age range 9‐14) were randomized into intervention and control groups containing 10 clubs each (intervention: 44 teams, n = 676 players; control: 48 teams, n = 733 players). The intervention group performed a structured NMT warm‐up operated by team coaches for 20 weeks. The main outcome measure was the prevalence of football‐related overuse LE injuries and injuries were tracked via weekly text messages. The average weekly prevalence of overuse LE injuries was 11.6% (95% CI: 11.0%‐12.2%) in the intervention group and 11.3% (10.7%‐11.9%) in the control group. The most common anatomical locations were the knee (weekly prevalence 6.0% in the intervention group and 5.7% in the control group) and heel (2.4% and 2.6%). There was no difference in the prevalence of overuse LE injuries between the groups: odds ratio (OR) 1.01 (95% CI: 0.99‐1.03). In conclusion, NMT warm‐up was equal to standard practice warm‐up in preventing overuse LE injuries in children's football during a follow‐up of 20 weeks.

The aim of this study was to determine the 4‐week prevalence of pain medication use in youth athletes, the type of medication used, the reasons for use, and from where the athletes obtained the medication. 466 handball players (aged 14‐18) were surveyed about their pain medication use within the preceding 4 weeks. The questionnaire consisted of 3 parts: type of pain medication used (if any; non‐steroidal anti‐inflammatory drugs (NSAIDs), acetaminophen/paracetamol, and acetylsalicylic acid (ASA)), the reasons for use, and from where it was obtained. 190 players (41% [95% CI 36%‐45%]) reported pain medication use within the last 4 weeks. Paracetamol was the most reported type (n = 157, 83% [95% CI 77%‐88%]), followed by NSAIDs (n = 98, 52% [95% CI 44%‐59%]); 67 reported “injury‐related reasons” for their use, and most participants reported to obtain the pain medication via “from home or bought over‐the‐counter (OTC)” (n = 167, 88% [95% CI 82%‐92%]). Pain medication use in youth handball players is common, particularly among female players, and a substantial proportion of the overall use is due to injury‐related reasons. The vast majority of the players got their pain medication from home or purchased it OTC. Further research is needed to comprehend these patterns of use, including the long‐term use.

Musculoskeletal injuries (MSI) normally related to sports occur to a large degree during physical activity in soldiers from special operations forces (SOF) and are the leading course for disability in military personnel. Efforts to prevent these injuries have been initiated through human performance optimization programs in several SOF´s. However, to provide the best conditions for the development of such strategies initially a comprehensive description of the injury epidemiology in this very unique population is required. Overall, studies indicate that more than half of SOF Operators—who have training amounts similar to elite athletes—experience one sports‐related injury per year, and the most common sites of injury are the shoulder, lumbar spine, and knee. Around half the injuries are acute, and the other 50% are chronic injuries. Although the type of injury is mapped, there is a lack of data regarding causes, mechanisms, and severity of injuries.

This prospective cohort study investigated the relationships between cumulative training loads measured in arbitrary units (AU), non‐training stress levels, and athletic injury risk in one team of male collegiate ice hockey players. Measures of athlete training load and non‐training stress were recorded each on‐ice session over one season. Daily load and stress sums were calculated for the two‐day and two‐week periods preceding each on‐ice session. Athletic injuries were also recorded, and odds ratio analyses were used to determine relationships between training load and injury risk, as well as non‐training stress and injury risk. Athletes who exerted training loads of 360 AU‐540 AU and of 540 AU‐1380 AU over 2 days experienced significantly greater odds of injury compared to athletes who exerted training loads <360 AU and <540 AU, respectively. This study concluded that as two‐day training load increases, so do the odds of injury in this sample. In an effort to reduce the odds of athletic injury, the monitoring of individual two‐day cumulative training load should be incorporated into the training programs of elite ice hockey players.

In this prospective cohort study, the aim was to examine any association between pre‐season training load and overuse problems (OP) in low back, knee, and shoulder in Icelandic elite male handball players. A total of 139 players participated, answering the OSTRC overuse questionnaire weekly during a 6‐week period. The training volume and intensity were registered by the coaches. The average weekly OP prevalence for shoulder was 40% (95% CI 36% to 44%), for knee 33% (95% CI 28% to 38%), and for low back 31% (95% CI 26% to 36%). Substantial overuse problems (SOP) were 14% (95% CI 11% to 17%) for shoulder, 11% (95% CI 10% to 12%) for knee, and 6% (95% CI 4% to 8%) for low back. The knee was most susceptible for OP with weekly number of training and training hours associated with OP and SOP. For individual training factors, running (OP; OR = 1.30, SOP; OR = 1.59), and shooting practice (OP; OR = 1.82, SOP; OR = 3.22) had the highest associations for knee problems. Jumping was associated with OP in low back (OR = 4.55). Handball players are most susceptible for OP in knees during their pre‐season. Every week, 30% participated with (SOP), affecting their performance and participation.

This study determined the point prevalence and factors associated with low back pain (LBP) in retired Great Britain's (GB) Olympians. Six hundred and thirteen retired athletes completed a cross‐sectional survey. Prevalence of LBP (pain on most days in the past 4‐weeks) was 32.1%. LBP was associated with a prior significant low back injury [aOR 2.51; 95% CI, 1.60‐ 3.92, P < .001] and a change from a healthy to a high BMI [aOR 2.21; 95% CI, 1.46‐3.34, P < .001]. Fewer cases of LBP were reported in those with a moderate training volume [aOR 0.29; 95% CI, 0.18‐0.48, P < .001] and those aged 75 years and older [aOR 0.51; 95% CI, 0.29‐0.91, P = .022]. Chronic LBP (symptoms past ≥12‐weeks) was associated with a higher pain severity [aOR 1.18; 95% CI, 1.02‐1.37. P = .031], widespread pain [aOR 2.62; 95% CI, 1.15‐5.99, P = .022], anxiety (aOR 2.99; 95% CI, 1.14‐7.80, P = .025), and depression [aOR 2.47; 95% CI, 1.08‐5.63, P = .031]. LBP is common in retired GB Olympians. Chronic symptoms were associated with features of central sensitization and imply that different pain mechanisms are involved in those with persistent symptoms. Strategies to promote health among retired athletes should consider the importance of psychological factors in the management of back pain.

Neuromuscular training (NMT) warm‐up programs are effective in reducing injury rates in youth team sports, including basketball, with greater adherence improving their effectiveness in preventing injuries in sport. To understand player adherence to a SHRed Injuries Basketball NMT (SIB NMT) warm‐up, we developed and utilized an observational tool to assess NMT exercise fidelity and compared exercise fidelity in boys and girls. Reliable methods for use of the SHRED Injuries Basketball Observation Tool (SIB OT) were established through two rounds of training. The percent agreement between raters was 66.09% for round one and 68.63% for round two. Sixty‐six youth basketball players (20 male and 46 female; median age 16) performing the SIB NMT were filmed. Exercise fidelity was assessed from video clips using the SIB OT. Overall exercise fidelity scores were based on total score achieved/total score attempted x100. The mean exercise fidelity score for boys [x ̅ = 57.35% (95% CI 53%‐62%)] was lower than for girls [x ̅ = 65.51% (95% CI; 62%‐69%)] (t = −2.88, P = .0027). Future research should focus on implementation strategies to improve exercise fidelity for NMT warm‐up programs in youth sport and further examine the impact of exercise fidelity on the preventative effect of NMT warm‐ups in youth sport.

The percent agreement between raters was 66.09% for round one and 68.63% for round two. Sixty‐six youth basketball players (20 male and 46 female; median age 16) performing the SIB NMT were filmed. Exercise fidelity was assessed from video clips using the SIB OT. Overall exercise fidelity scores were based on total score achieved/total score attempted x100. The mean exercise fidelity score for boys [x ̅ = 57.35% (95% CI 53%‐62%)] was lower than for girls [x ̅ = 65.51% (95% CI; 62%‐69%)] (t = −2.88, P = .0027). Future research should focus on implementation strategies to improve exercise fidelity for NMT warm‐up programs in youth sport and further examine the impact of exercise fidelity on the preventative effect of NMT warm‐ups in youth sport.","PeriodicalId":75247,"journal":{"name":"Translational sports medicine","volume":"4 1","pages":"817 - 825"},"PeriodicalIF":0.0,"publicationDate":"2021-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44386997","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}

Previous cadaveric studies have identified effective stretching positions for the posterior shoulder capsules; however, it is unknown whether these stretching positions are also effective in overhead athletes. This study aimed to investigate whether passive tension was generated in the posterior shoulder capsules in baseball players during stretching positions identified in previous cadaveric studies. Fifteen male baseball players without prior shoulder injuries or surgeries participated in this study. We measured the shear moduli of the middle and inferior posterior capsules of the dominant shoulder in the resting (neutral shoulder internal/external rotation at 30 degrees of flexion) and stretching (maximal shoulder internal rotation at 30 degrees of scapular plane elevation (scaption)) positions using ultrasound shear wave elastography. The shear moduli of the middle posterior capsule were significantly higher in the stretching position than in the resting position (resting vs stretching: 20.9 vs 34.6 kPa, P < .001); however, there was no significant difference in the shear moduli between both positions in the inferior posterior capsule (22.3 vs 29.5 kPa, P = .120). Our results revealed that a large amount of passive tension is generated in the middle posterior capsule during shoulder internal rotation stretching at 30 degrees of scaption in overhead athletes.
先前的尸体研究已经确定了肩部后囊的有效拉伸位置；然而，尚不清楚这些伸展姿势是否对头顶运动员也有效。本研究旨在调查棒球运动员在先前尸体研究中确定的拉伸姿势中，后肩关节囊中是否产生被动张力。15名男性棒球运动员参与了这项研究，他们之前没有肩部受伤或做过手术。我们使用超声剪切波弹性成像测量了主肩在静息（30°屈曲时的中性肩内/外旋转）和拉伸（30°肩胛平面抬高（舟骨）时的最大肩内旋转）位置的中下后囊的剪切模量。中后囊的剪切模量在拉伸位置显著高于静止位置（静止与拉伸：20.9vs 34.6kPa，P<.001）；然而，下后囊膜中两个位置的剪切模量没有显著差异（22.3 vs 29.5kPa，P=.120）。我们的研究结果表明，在头顶运动员30度肩关节内旋转拉伸过程中，中后囊膜会产生大量被动张力。
