Between Repetitive Head Traumas and Academic Performance of Non-Concussed High School Athletes: A Comparison of High And Low Contact Sports. Arch Sports Med Abstract Objectives: To assess the relation of repeated subconcussive head traumas and the academic performance and neuropsychological functioning of non-concussed high school athletes participating in high and low levels of contact sports. Design: Cross-sectional study. Setting: High school sports Patients or Other Participants: A total of 641 non-concussed high school athletes, consisting of 464 males and 177 females participating in a variety of sports. Intervention: The independent variables are the two levels of contact sport groups were identified, High and Low Contact groups, who were assumed to sustain varied degrees of repetitive subclinical head traumas, based on epidemiological concussion data. Main Outcome Measures: The independent variables were the High and Low Contact Groups. The dependent variables were (1) baseline test results of the Immediate Post-Concussion Assessment and Cognitive (ImPACT) and (2) grade point averages (GPA) across four quarters of the school year. Results: High Contact athletes obtained lower GPAs and had significantly poorer scores in ImPACT Visual Motor Speed and Reaction Time than the Low Contact athletes. Conclusions: The findings, with medium effect sizes, suggested that repetitive subconcussive head traumas are associated with significant lowering of school grades and neuropsychological functioning in high school athletes. The clinical relevance of this association is not known and the findings of this study should be cautiously interpreted.

Background: The combination of swimming, throwing, and physical contact in water polo places players at risk for a range of injuries. Prior research has demonstrated high rates of head and shoulder injuries among competitive water polo players. However, there is limited injury data regarding adolescent water polo players. Methods: We identified patients under the age of 18 with water polo-related concerns treated at the sports medicine divisions at our institution across a five-year span. History, physical examination, imaging, diagnoses, and treatment outcomes were recorded. Results: We identified 56 adolescent water polo players (mean age = 15.3 years). Injuries to the shoulder (23) and head (11) were most common. Concussion (11), rotator cuff pathology (8), shoulder instability (6), and scapular pathology (6) were the most common diagnoses. Mechanisms of injury included throwing (14), swimming (12), and physical contact with opponents or the ball (12). The most frequently employed diagnostic evaluation protocol included a history and physical exam with an x-ray (18). Physical therapy (40) and rest from sports (29) were the most frequently recommended treatments with surgery being rarely indicated (6). Conclusions: Among our cohort of patients, injuries to the head and shoulder were the most commonly seen in adolescent water polo players. Throwing, swimming, and acute unexpected contact were all frequently described by patients as contributing to their injuries. Providers and coaches should be aware of the unique physical demands of water polo as well as the most common injuries and medical management of these athletes.

Propuse: The objective was to verify the acute influence of the Leg Press 45° (LP) exercise on the functional stress of the hamstring muscles, through a test of maximum repetitions in 13 men. Methods: Four different situations of the stress of the previous hamstring muscles were induced by the combination of the LP, Knee Flexor (KF), Stiff (ST) and Elbow Flexion (EF) exercises, to measure the level of reduction of the hamstring muscles functional capacity after each exercise and compares them to the LP. The procedures consisted of performing the KF exercise 10s after the execution of the EF, and KF 10s after the execution of the ST, and KF 10s after the execution of the KF itself, and FJ 10 s after the execution of the LP. Results: The functional stress of the hamstring muscles caused by the execution of the four exercises subsequently (10s) to the execution of the KF was: EF = 9.2%, ST = 53.1%, KF = 70.8% and LP = 15.4%. When comparing functional reductions between exercises, we found a significant difference between LP and ST (p = 0.001) and between LP and KF (p = 0.001). However, the reduction was not significant when comparing the LP and EF (p = 0.414). The ST also showed a significant difference for the KF (p = 0.001) and for the EF (p = 0.001). Conclusion: The level of functional reduction of hamstring muscles in the execution of the leg press 45° was similar to that verified in EF, both being significantly lower than the functional reductions in ST and in the KF itself.

Weaker neck strength has been suggested as a potential risk factor of sport related concussion in female soccer athletes. The purpose of this study was to examine sex differences in neck muscle strength characteristics in multiple directions. A total of 52 high school soccer players (17 Females/35 Males) with no history of concussion participated. Subjects were instructed to perform three maximum voluntary isometric contractions for eight directions: flexion, right / left diagonal flexion, right/left lateral flexion, right/left diagonal extension, and extension. Peak force, normalized peak force, force steadiness, force ratio, and rate of force development were calculated and used for statistical analyses. Based on the normality test on each dependent variable, either independent t-tests or Mann-Whitney U-tests were used to compare sex differences (P < 0.00625: Adjusted for multiple comparisons). Males had significantly higher peak force in right lateral flexion and extension directions and rate of force development in left diagonal flexion and left lateral flexion direction compared to females (P < 0.00625). After values were normalized to body mass, significant sex differences were only observed with peak force in right lateral flexion. Significant sex differences were found mostly in secondary directions. Continued research efforts are needed to determine how neck strength characteristics may influence sport related concussion risk in soccer athletes.

Objectives: This study examined whether omega-3 polyunsaturated fatty acid (n-3 PUFA) supplementation lowered the heart rate (HR), rating of perceived exertion (RPE) and oxygen uptake (V̇ O 2 ) and accordingly improved cycling performance in a time trial. Design: In a randomised, crossover, double-blind study, trained male cyclists (n = 10) were supplemented for 4 weeks with n-3 PUFA (5.7 g/day of eicosapentaenoic acid (EPA) and docosahexaenoic (DHA)) and 4 weeks with placebo (6g olive oil), with a 4-week washout period. Methods: Cycling performance trials (45 min preload at 70% maximal work rate (Wmax) followed by 15 min time trial) were carried out prior to and following both supplementation periods. Fatty acid composition of blood total lipids was analysed prior to and in response to supplementation. Results: Whole blood n-3 PUFA (% total fatty acids) increased from 1.67% (SD = 0.99%) to 3.72% (SD = 1.22%) (p < 0.05) following 4 weeks n-3 PUFA supplementation. Submaximal measures of V̇ O 2 , HR, respiratory exchange ratio (RER) and RPE were unaffected by supplementation. Time trial performance (mean power W) was unchanged by n-3 PUFA (pre 239 W, SD = 34 W vs post 243 W, SD = 33 W), as were measures of V̇ O 2 , HR, RER and RPE during the time trial. Conclusions: High dose n-3 PUFA supplementation for 4 weeks did not improve cycling performance or attenuate the physiological variables usually associated with improved cycling performance, i.e. V̇ O 2 and HR, in a repeated-measures, placebo-controlled, crossover design study. It is possible that the exercise protocol used in the study was of insufficient intensity for the n-3 PUFA to show beneficial affects due to the highly trained nature of the cyclists.

We aimed to report sex differences in ventilation during EVH challenge in University athletes while exploring whether they achieve inspiratory target. Seventy-seven athletes (n = 42 males, n = 35 females) performed six-minute EVH chal lenge involving compressed gas (5% CO 2 , 21% O 2 and balance N 2 ) inhalation at an inspiratory target of 85% MVV indirect . Ventilation was recorded every 15 seconds during EVH challenge with pre-and post-challenge measurements of FEV 1 determining outcomes. Males reached significantly higher ventilation (412.0 ± 55.0 L) compared with female athletes (292.5 ± 43.2 L), (F = 3890.0, p < 0.05), and a significant effect of time (F (23) = 3689.8, p < 0.05) as well as interaction (F = 106.3, p < 0.05) was noted. There were significant differences in cumulative ventilation attained (679.5 ± 146.6 L) during the 6-min EVH compared with inspiratory target (807.0 ± 169.6 L), amongst both sexes (t (76) = 5.0, p < 0.05) as well as EIB positive and negative groups (p < 0.05). The results support sex differences in ventilation achievement and suggest EVH inspiratory target of 85% MVV indirect is generally not reached by athletes, thereby requiring re-evaluation and further exploration of sex differences in future EVH studies.
我们的目的是报告大学运动员EVH挑战期间通气的性别差异，同时探索他们是否达到吸气目标。77名运动员(42名男性，35名女性)进行了6分钟EVH挑战，包括吸入压缩气体(5% CO 2, 21% o2和平衡n2)，吸气目标为85% MVV间接。EVH刺激期间每15秒记录一次通气，刺激前后测量FEV 1确定结果。男性运动员的通气量(412.0±55.0 L)明显高于女性运动员(292.5±43.2 L) (F = 3890.0, p < 0.05)，且时间(F (23) = 3689.8, p < 0.05)和相互作用(F = 106.3, p < 0.05)的影响显著。EVH 6min累计通气量(679.5±146.6 L)与吸气目标(807.0±169.6 L)在两性间(t (76) = 5.0, p < 0.05)及EIB阳性、阴性组间(p < 0.05)均有显著差异。结果支持了通气成就的性别差异，提示运动员一般无法达到EVH间接吸入85% MVV的目标，因此需要在未来的EVH研究中重新评估和进一步探索性别差异。

A 30-year-old elite professional footballer was diagnosed with post-concussive epilepsy. Following neurological evaluation he was found to have cardiac dysrhythmia, rather than epilepsy, causing cognitive dysfunction. The cardiac abnormality was identified during his electroencephalogram (EEG), which included a modified lead 2 rhythm strip in which he was shown to have marked bradycardia and pulses bigeminy.

Tibial spine fractures are rare lesions which usually occur in adolescent but rare in adults it leads to discontinuity of anterior cruciate ligament. It has been the subject of several publications concerning its anatomopathological presentation and its treatment. The Meyers and Mac Keever classification, modified by Zaricznyj, are the most used and allowed to classify the lesions into 4 types. The treatment of displaced fractures requires surgical reduction and fixation in order to achieve adequate tension in the anterior cruciate ligament and to reduce the risk of laxity, in order to better check the integrity of the anterior cruciate ligament and to guarantee a good stability of the knee and to reduce the risk of laxity, several fixation techniques are described ranging from racking and screwing to osteosuture, currently the surgical reduction can be performed under arthroscopy with the same basic principles of osteosynthesis as arthrotomy but with more advantage and innovative and attractive techniques.

The treatment of displaced fractures requires surgical reduction and fixation in order to achieve adequate tension in the anterior cruciate ligament and to reduce the risk of laxity, in order to better check the integrity of the anterior cruciate ligament and to guarantee a good stability of the knee and to reduce the risk of laxity, several fixation techniques are described ranging from racking and screwing to osteosuture, currently the surgical reduction can be performed under arthroscopy with the same basic principles of osteosynthesis as arthrotomy but with more advantage and innovative and attractive techniques.","PeriodicalId":167640,"journal":{"name":"Archives of Sports Medicine","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131678721","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}
There are numerous benefits attached to the idea of lifelong physical activity. Because of this, various governmental and sports organisations seek to promote positive behaviours and potential health aspirations through the use of sport. This critical commentary seeks to highlight some of the issues that surround this topic, most notably the lack of suitable training or understanding for many of the practitioners who deliver youth sport (coaches and teachers). The implications for incorrect or limited understanding within the context of youth sport practice sessions are numerous, particularly when the ideas of performance, competition, and talent are used but not necessarily understood, with increased drop-out rates perhaps of most significance. The contention of this commentary is that those delivering youth sport must develop an appreciation of evidence-based practice that, fundamentally, places the developmental needs of youth at its heart, prioritises participation, and sees the use of competition as a means to an end, not the end itself
