This study compared the efficacy of linear, non-linear and differential methods on variables related to ACL injury risk of a side-step cutting task in male and female basketball players. Thirty males and thirty females practiced basketball skills in sixty 90-minute sessions across 5 months. Ten players trained in each of the LP, NLP and DL female/male groups separately. Before and after the intervention, each player was tested on a side-step cutting task. A repeated 3 × 2 × 2 factorial ANOVA with repeated measures was performed for each biomechanical variable. Variables (trunk, hip, and knee flexion angle, knee valgus angle, ankle dorsiflexion angle, hip, knee, and ankle ROM, peak VGRF and knee extension/flexion, knee moment and ankle dorsiflexion moment) all revealed significant test by group interactions (P < 0.05) but no significant group by sex interactions (P > 0.05). In both sex, biomechanical changes were better in the NLP, followed by the DL and LP. It is argued that the advantage of the NLP method results from increased exploration of movement solutions induced by the manipulation of task constraints. Therefore, according to the NLP, it is possible to manipulate the constraints without feedback and the model/pattern can keep the athlete away from possible risks.

Participation in outdoor sports increases exposure to ultraviolet radiation, necessitating mitigation through sunscreen use. This prospective study examined the effects of sport, setting (practice vs. competition), gender, age and geographic location on sunscreen use and education among youth athletes in various sports. Six hundred and twelve athletes ≤18 years old completed an online survey on sunscreen education and use during competitions and practices. Regardless of sport, reported sunscreen use was higher during practices than competition (p < 0.0001). Sunscreen was used most by swimmers/divers (odds ratio: OR ≥ 1.9, p < 0.001) and least by American football players (OR ≤ 0.57, p ≤ 0.001). Coaches mentioned sunscreen use the most in track and field (OR 1.84, p = 0.001) and the least in American football (OR 0.67, p = 0.03). Athletes used sunscreen more if they were female (OR ≥ 1.9 1.38, p ≤ 0.06) and younger (age OR ≤ 0.88, p < 0.001). In conclusion, youth athletes differ in sunscreen use by sport and setting, highlighting the need for continued photoprotective education.
参加户外运动会增加紫外线辐射量,因此必须使用防晒霜来减少紫外线辐射。这项前瞻性研究考察了运动项目、环境(练习与比赛)、性别、年龄和地理位置对青少年运动员使用防晒霜和接受防晒教育的影响。612 名年龄小于 18 岁的运动员完成了一项关于防晒教育和在比赛和训练期间使用防晒霜的在线调查。无论是哪种运动,在练习期间使用防晒霜的比例都高于比赛期间(p p p ≤ 0.001)。教练提到使用防晒霜最多的是田径(OR 1.84,p = 0.001),最少的是美式足球(OR 0.67,p = 0.03)。如果运动员是女性(OR ≥ 1.9 1.38,p ≤ 0.06)和年轻(年龄 OR ≤ 0.88,p ≤ 0.06),则使用防晒霜的比例更高。

Anti-gravity treadmills have been used in rehabilitation to manipulate exposure to loading and to prescribe return to outside running. Analysis is typically restricted to the vertical plane, but tri-axial accelerometry facilitates multi-planar analysis with relevance to injury mechanism. In this case a professional male soccer player, 4 weeks post-operative surgery to repair a medial meniscectomy, 8 months after Anterior Cruciate Ligament reconstruction to the same knee, completed anti-gravity treadmill running at 70-95% bodyweight (BW) at 5% increments. Tri-axial accelerometers were placed proximal to the Achilles tendon of the injured and healthy leg, and at C7. The planar acceleration at touchdown highlighted an increase at 85% BW, identifying 70% and 85% BW as discrete loading progressions. C7 (3.21 ± 0.68 m·s-2) elicited lower (P < 0.001) vertical acceleration than the lower limb (9.31 ± 1.82 m·s-2), with no difference between limbs suggesting bilateral symmetry. However, in the medio-lateral plane the affected limb (-0.15 ± 1.82 m·s-2) was exposed to lower (P = 0.001) medio-lateral acceleration than the non-affected limb (2.92 ± 1.35 m·s-2) at touchdown, indicative of bilateral asymmetry. PlayerLoad during foot contact was sensitive to accelerometer location, with the affected limb exposed to greater loading in all planes (P ≤ 0.082), exacerbated at 90-95% BW. Tri-axial accelerometry provides a means of assessing multi-planar loading during rehabilitation, enhancing objective progression.

The incidence of paediatric fractures among winter sport athletes is not adequately studied. Our objective was to categorize fractures that occurred in paediatric skiers and snowboarders at a single ski resort. X-rays of 756 skiers/snowboarders aged 3-17 diagnosed with a fracture were categorized using the Salter-Harris (SH) classification. SH fractures were seen in 158 (21%) patients, with 123 (77%) being Type II. There were no significant differences between patients with a SH fracture and patients with a non-SH fracture for age, sex, snowboarding or skiing, mechanism of injury, terrain or the resort conditions on the day of injury. The most common mechanism of injury was falling onto snow while collisions resulted in more severe injuries. Compared to fractures without growth plate involvement, a higher proportion of SH fractures were seen in the humerus, radius, fibula and thumb; a lower proportion of SH fractures were observed at the tibia and clavicle.
有关冬季运动运动员中儿童骨折发生率的研究并不充分。我们的目标是对一个滑雪胜地的儿童滑雪和单板滑雪运动员的骨折情况进行分类。我们采用 Salter-Harris (SH) 分类法对 756 名 3-17 岁滑雪/单板滑雪运动员的 X 光片进行了骨折分类。158名(21%)患者出现了SH型骨折,其中123名(77%)为II型。SH型骨折患者与非SH型骨折患者在年龄、性别、滑雪板或滑雪运动、受伤机制、受伤当天的地形或度假村条件等方面没有明显差异。最常见的受伤机制是摔倒在雪地上,而碰撞导致的受伤更为严重。与未累及生长板的骨折相比,肱骨、桡骨、腓骨和拇指的SH骨折比例较高;胫骨和锁骨的SH骨折比例较低。

This study aimed to evaluate depression, anxiety, and stress prevalence and correlates among professional football team medical and allied health staff (MAHS) in Turkey. An online survey was sent to all MAHS (n = 865) attending the professional development accreditation course organized at the end of the 2021-2022 football season in Turkey. Three standardized scales assessed depression, anxiety, and stress. A total of 573 staff participated (response rate = 66.2%). 36.7% of MAHS reported at least moderate severity depression, 25% anxiety, and 80.5% stress. Younger (26-33 years) and less experienced (6-10 years) MAHS reported higher stress scores than their older (50-57 years) and more experienced (>15 years) counterparts (p = 0.02 and p = 0.03, respectively). Masseurs (compared to team doctors) and staff without a second job (compared to those with a second job) reported higher depression and anxiety scores (p = 0.02, p = 0.03, p = 0.03, p = 0.02, respectively). Depression, anxiety, and stress scores of MAHS whose monthly income was less than $519 were higher than those whose income was more than $1036 (all p < 0.01). Findings demonstrated that professional football team MAHS suffer from symptoms of mental-ill-health at substantial rates. In light of these results, organizational policies should be implemented to proactively support the mental health of MAHS working in professional football.

Our study aimed at detecting a potential cumulative effect of subsequent concussions on the neural activation patterns of young rugby athletes with or without concussion history. Event-related brain potential (ERP) data from 24 rugby players, 22-year-old on average, were retrospectively examined. All underwent a Sport Concussion Assessment Tool (SCAT2) during preseason and an on-site ERP task (P300) following a recent concussion event (<48 hours). Sixteen players suffered at least one concussion in the previous 3 years and eight were without self-reported past concussion. While no differences were reported between groups regarding symptom appraisal on the SCAT2 assessment, ERP revealed significantly decreased P3b amplitude and a trend for increased P3b latency in players who experienced prior concussions. Our data thus support the cumulative effect of concussions on neuroelectric events in young rugby players, highlighting the importance of managing player's concussion load to reduce the risk of long-term injuries.

The purpose of this protocol was to adapt and validate the English version of the Short Musculoskeletal Function Assessment (SMFA) into Chilean Spanish according to the World Health Organisation guidelines. This is a cross-sectional study of 897 surveys of patients with non-traumatic surgical orthopaedic pathologies. We analysed internal consistency, validity, and acceptability, including correlation with the short form 36 (SF-36) medical score. The validation included 900 participants with a response rate of 99,66%, with excellent internal consistency (Cronbach's α = 0.962). The Dysfunction and Bother Index items showed a value of 0.952 and 0.884 respectively, eliminating one item in the Dysfunction sub-scale. The principal component analysis was forced to four factors explaining 55.5% of the variance. SMFA-CL sub-scales are significantly correlated with SF-36 components and subcomponents. The first version of the SMFA-CL version (Spanish-Chilean) scale is reported. This culturally adapted score demonstrated a high rate of reliability, validity, and ability to objectively evaluate foot and ankle pathologies.

The objective was to evaluate the effects of acai supplementation (AS) on markers of muscle damage. Twelve men participated in the 21-day study. All performed the damage protocol (DP) in two moments, separated by 7 days. The DP consisted of 10 sets of 10 CMJs, with a recovery of 1 min between sets. The AS was performed for 7 days with 40 g/day of dehydrated acai (GA) or placebo (GP). Blood parameters (CK, LDH and Trolox-equivalent antioxidant capacity - TEAC) were evaluated at 0 h and 24 h. Ultrasound images (VL, RF and GM), DOMS in lower limbs and isometric peak torque (IPT) of knee extensors and flexors were evaluated at 0 h, 24 h, 48 h and 72 h after DP. A time-treatment interaction was observed for TEAC (p = 0.01), in which the GA presented increases of 11% after 24 h. Similarly, time-treatment interaction was observed for knee flexors IPT (p = 0.02), where GA showed superior recovery after 24 h (GA = 108 ± 23 vs. GP = 92 ± 24 N∙m) and 72 h (GA = 113 ± 31 vs. GP = 98 ± 26 N∙m). No significance was observed in the fatigue index for knee extensors (p = 0.75) and flexors (p = 0.89), indicating similar fatigue in both situations. We concluded that AS increased the TEAC and promoted faster recovery of the knee flexors IPT when compared to GP.

Hip strength has been shown to influence the incidence of injury in women's football. The first objective of our study was to examine the differences in isometric strength of the adductors and abductors between two test positions (0° vs. 45° hip angle). Our second objective was to verify the sensitivity of the two test positions in discriminating between women footballers with and without a history of groin pain in the last twelve months. One hundred and one elite players from the Slovenian women's football league were tested. The isometric strength of the adductors, abductors, and the ratio between hip abductor and adductor strength in two different test positions were assessed. We found statistically significant differences (p < 0.05; effect size range 0.12-0.13) between the two test positions in hip adduction, abduction strength, and abductor/adductor strength ratio. The ROC analysis showed that only the abductor/adductor strength ratio at the 0° hip angle position can differentiate between players with and without a history of groin pain, with an optimal cut-off point of ≤ 1.01 (p < 0.05; AUC = 0.734). The results should help practitioners plan hip strength training for returning to sport or preventing groin pain among women football players.

This study investigated the extent of injury incidence and burden in a professional women football team of the Scottish Women's Premier League during two seasons. All injuries causing time-loss or required medical attention were recorded prospectively. A total of 671 injuries, 570 requiring medical attention and 101 causing time-loss were recorded in 41 players. Injuries occurring with National Team resulted in 12% of the club's international players' lay-off. Overall injury incidence was 11.1/1000-hours and burden was 368.9 days/1000-hours. Injury incidence (23.9/1000-hours vs 8.2/1000-hours) and burden (1049.8 days/1000-hours vs 215.1 days/1000-hours) were higher for match compared to training. Foremost mechanism of match injury burden was indirect-contact, which was different than the non-contact predominantly observed for training injury burden. Injury incidence, burden and patterns differed between training, match and playing positions. Tailoring injury-risk reduction strategies considering context, circumstances and playing position deserve consideration to enhance player's injury resilience in professional women footballers.
