Objectives: To test the association between PPS and sports performance; does a reduction of an elevated PPS improve performance stability and overall performance in Olympic sailors? \u0000Methods: The case study included two male athletes during eight months of observation prior to and during Olympic sailing. The daily PPS self-measurements served as feedback guide for persistent stress and ANS dysfunction. Performance stability, overall performance and PPS measure were assessed at three intervals. \u0000Results: At baseline, the median PPS was 83, the performance stability was inferior to the mean top 10 competitors, and the overall performance was rank eight. During the observation period, PPS, performance stability and overall performance improved incrementally and significantly. This eventually led the sailors to achieve an Olympic Gold. The PPS, performance stability, and overall performance were all internally closely associated (correlation coefficients: r > 0.70; p < 0.001). \u0000Conclusion: The study may suggest a link between persistent stress and ANS dysfunction as assessed by PPS on one side and performance stability and overall performance on the other side.","PeriodicalId":17085,"journal":{"name":"Journal of Sports Medicine & Doping Studies","volume":"16 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86291902","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}

{"title":"Statewide Interscholastic Testing Programs for Performance-Enhancing Drugs on the Decline: How We Got Here","authors":"G. Wimer, A. Parish","doi":"10.4172/2161-0673.1000176","DOIUrl":"https://doi.org/10.4172/2161-0673.1000176","url":null,"abstract":"National surveys indicate that 1%-4% of high school students report use of anabolic steroids [1]. Steroids have a variety of benefits in regard to athletic improvement. They are used to increase muscle size and strength as well reduce body fat. Additionally, they provide quicker recovery between workouts which allows athletes quicker recovery after strenuous exercise. This quick recovery allows them to work out longer, harder, and more often [2]. Steroids come in two forms; injectable and oral. The most popular of the injectable types include Deca-Durabolin, Depo-Testosterone, and Equipoise while of the oral steroids; Andadrol, Dianabol and Winstrol are the most widely used by teenage athletes. Both injectable and oral steroids can have serious side effects. Some of these side effects include acne, swelling, development of sexual characteristics of the opposite gender, mood swings, aggressive behavior, increase in poor cholesterol levels, and stunted growth. Perhaps even more troubling is the fact that oral based steroids produce liver toxicity and can damage other internal organs [2]. Despite these severe side effects, teenage athletes have continued a steady progressive movement toward their use with the hope of improving their abilities. In 2006, New Jersey became the first state to mandate testing of performance-enhancing drugs (PED’s) for high school athletes; soon after, Florida, Illinois, and Texas followed suit [3]. The impetus to test high school athletes may have been tied to highly publicized cases like the 2003 steroid-linked suicide of Taylor Hooten or the more recent discovery of the distribution of performance enhancing drugs to two high school seniors as a part of the Biogenesis scandal [4]. Additionally, in 1995 the U.S. Supreme court ruled that drug testing high school athletes was constitutional which paved the way for PED testing to commence. The leaders of participating high school associations use the findings of the aforementioned national survey along with their stated concern of fostering fair play and protecting the health of their youth to justify drug testing of athletes. Given the deactivation of the statewide PED testing program in Florida, and most recently in Texas, this paper looks to illuminate the issues that hamper effective interscholastic PED testing.","PeriodicalId":17085,"journal":{"name":"Journal of Sports Medicine & Doping Studies","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2016-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73539813","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}

The disease is usually mono articular and commonly involves knee joint, but it can also occur in shoulder, elbow, hip, ankle and wrist joints. A review of the literature produced 30 case reports of synovial chondromatosis of the wrist with only five cases showing recurrence (5/30, 17%). Because of its low prevalence and nonspecific symptoms, it can present diagnostic difficulties and lead to a delay in treatment. \u0000Case: We report a 6 month follow up case of a 29 year old right hand dominant male who presented with complaint of pain and swelling in right wrist joints of four months duration. Plain X-ray revealed lytic lesion at distal end of right ulna with multiple radio opaque deposits. MRI and FNAC were in favour of Synovial chondromatosis. Patient underwent synovectomy and excision of calcific lesion through a dorsoulnar approach and a separate incision over radial styloid under general anaesthesia. Histopathology confirmed the diagnosis of Synovial chondromatosis. Patient had no recurrence till last follow up (6 Month). \u0000Conclusion: Synovial chondromatosis of wrist joint is extremely rare. A close coordination between the clinician, radiologist and pathologist is essential for accurate diagnosis and management.","PeriodicalId":17085,"journal":{"name":"Journal of Sports Medicine & Doping Studies","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2016-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82825614","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}

Following menisectomy the tibiofemoral contact area decreases while the contact forces increase. Meniscal allograft transplantation (MAT) offers the potential to restore partial load-bearing, decrease symptoms, and provide chondroprotective effect. Ideal patient for MAT should have normal alignment, stable knee, abscence of cartilage damage and has less than 50 years-old. Several open and arthroscopic MAT techniques have been described. The succesful of MAT is to use a minimal invasive technique without sacrificing the precise anatomic reconstruction of the original meniscofemoaral and meniscotibial relationships. Anatatomical position, appropriate sizing of the graft, and fixation method are crucial key points to have good results. In general there are three fixation methods: soft tissue fixation, suture fixation through transoseous tunnels, and bone plugs press-fit fixation. However, inferior biomechanical and contact pressure have been reported with soft tissue and transosseous tunnels compared with the bone block technique.","PeriodicalId":17085,"journal":{"name":"Journal of Sports Medicine & Doping Studies","volume":"16 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2015-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87001292","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}

Healing process occurs via scar tissue formation leading to poor outcomes for patients. Current surgical and non-surgical treatment modalities lead to sub-optimal tendon healing and each of them have complications. Therefore, to repair and restore tendon structure and function, a tendon graft is needed; therefore autografts, allografts and xenografts have been used. However, each of these grafts is associated with several limitations such as donor site morbidity and pain, poor biocompatibility, disease transmission and immune reaction which lead to graft rejection and failure. Tissue engineering is an advancing field that can either augment surgical repair or provide an alternative method for Achilles tendon repair. Among the components of tissue engineering technologies, the present article has discussed scaffolds and emphasized on collagen-based biomaterials. This article illustrated the causes behind the essential need for tissue engineering in Achilles tendon repair. Furthermore, it described the current literature regarding the use of collagen in Achilles tendon repair and the main points regarding application of collagen biomaterials and scaffolds in tendon tissue engineering.","PeriodicalId":17085,"journal":{"name":"Journal of Sports Medicine & Doping Studies","volume":"7 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2015-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81545469","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}
