Methods: The patient is a 39 years old caucasian man, he arrived at the emergency department for high-impact trauma during sport activity. The diagnosis was avulsion of the volar plate at the proximal phalanx and extensor tendon rupture at the distal phalanx. The surgical approach has been reinsertion of the volar plate at the base of the middle phalanx with 2 micromyteck anchors and extensor tendon tenorrafy after stabilization with transarticular Kirschner wire. He was subsequently subjected to early and protected mobilization program. The patient was assessed with the PRWHE, VAS and ROM every 7 days after surgery. Results: The results obtained following the setted clinical protocol are encouraging for the VAS, that improved from 8 to 2 points from the first to the last evaluation. Also the PRHWE index gave excellent results going from an initial value of 88/100 to a ending value of 3/100. Conclusions: The patient reached an excellent recovery of flexion-extension of the proximal interphalangeal joint and distal interphalangeal joint, he reintegrated gesture and functionality of the finger and hand in ADL and sport activities, thanks to an early mobilization protocol and to a continuous adaptation of the splinting.","PeriodicalId":17085,"journal":{"name":"Journal of Sports Medicine & Doping Studies","volume":"36 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80919177","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}

Anaerobic oxidation of glucose-derivative from glycogen delivers energy 6 times faster than aerobic oxidation of glucose and oxidation of fatty acids; correspondingly, mental activity can perform as well 6 times faster as long as glycogen is available.   The mental profile of chess players correlates with cerebral processes such as attention, conflict solution, memory, motivation and recognition, which together constitute a specific chess-domain expertise.   A chess player may compete best when a) regularly physical exercise is carried out to compete in strenuous chess tournaments and to stimulate mental cognition, b) super compensated glycogen is accumulated in brain, muscle and liver by corresponding nutrition and physical and mental activities, and c. an active mental disposition is available for complex brain tasks during chess by complementary treatment schemes e.g., cogni-tive enhancement (CE) by chesstraining with chess boards, chess books, building chess images, visual observation of chess games, vocational training with chess, metacognitive training, and additionally regular light physical stress.   An illicit improvement of brain performance for chess playing may be achieved by several measures: 1. Increase of O2 supply by therapy with erythropoietin (EPO) for chess tournaments at high altitudes and for chess players with lung diseases 2. Increase of body glycogen by therapy with insulin 3. mental stimulation by caffeine   AAS, anabolic agents, amphetamines, nicotine and cocaine have no proven effect on quality of chess playing. Many steroid- and proteohormones such as cortisol, testosterone, ACTH, EPO, GH, hCG, IGF-I, Insulin, LH, present positive effects on brain development and cognition only when present in natural concentrations during development of brain. Pharmaceutical preparations show positive effects only at low baseline cognition. With elevated concentrations, these hormones present negative effects on mental cognition.   Actual CE drugs have effects only with persons at low cognitive baseline. With normal persons, CE is still below clinical significance.   Regular non-medical use of steroid and proteohormones in elevated concentrations and CE-drugs must also consider numerous side effects ranging from simple metabolic disturbances through cardiac problems to cognitive decline to tumorgenesis and sudden death.","PeriodicalId":17085,"journal":{"name":"Journal of Sports Medicine & Doping Studies","volume":"74 1","pages":"1-16"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81540902","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 is an abundance of tests and monitoring tools that have been used to describe the fatigue response of both individualand team-sport athletes. These tests typically include measures of neuromuscular function, subjective questionnaires, blood and salivary markers, or physical performance tests. Importantly though, the tests employed must be valid, reliable and practically convenient in applied settings. Investigators have commonly assessed fatigue measures during tournament competition [1-3] or over subsequent days following competitive matches [4-6] in an attempt to identify the time course of the fatigue-recovery cycle. This provides an understanding of how an athlete recovers from competition and guides training loads and recovery practices when athletes may be most vulnerable to nonfunctional overreaching and injury.","PeriodicalId":17085,"journal":{"name":"Journal of Sports Medicine & Doping Studies","volume":"209 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80593416","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}

Osteoporosis engages approximately about 200 millions of individuals, world widely. For instance, about 10 millions of Americans are affected and another 34 million are at risk of osteopenia [1]. Osteoporosis has been known as a silent disease. The affected patients do not often understand about the nature of their disease until it significantly develops so that the patients are often presented with osteoporosis related fractures [2]. Postmenopausal women are the most commonly affected population in the world and the fracture rates in postmenopausal Asian, American and African women have been reported to be 41, 54 and 91%, respectively [3]. During the postmenopausal period, the risk of fractures increases due to the accelerated bone loss because estrogen declines with age. Moreover, men are also affected by osteoporosis with the incidence of 20% [4]. Annually, $19 billion are accounted for osteoporotic fractures in health care expenditures which expected to rise to $25.3 billion in the future 10 years [5]. Each year, nearly 300,000 hip fractures, 547,000 vertebral fractures and almost 1,054,000 other fractures occur due to osteoporosis. Osteoporosis imposes more than 432,000 hospital admissions, 2.5 million medical office visits, and 180,000 nursing home admissions to the healthcare systems, annually [6]. Despite of several attempts, osteoporosis is still a considerable challenge for the governments.","PeriodicalId":17085,"journal":{"name":"Journal of Sports Medicine & Doping Studies","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91360390","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}

Here we addressed this contentious issue by assessing whether a double sigmoidal model could detect decrements in sporting performance attributed to introduction of drug testing protocols. \u0000Methods: Distances thrown by the top 25 male and female shot putters since the end of the 19th century were modelled using a double sigmoid. \u0000Results: First-phase peak acceleration in the men’s and women’s shot put was reached in 1981 and 1986 respectively coinciding with advent of systematic doping programs. Shot put performance of men and women underwent a second-phase decline of 5.3 m and 8.9 m, in 1991 and 1994, respectively. Performance decrements in women’s shot put were nearly double that for men, but much of this difference resulted from the reduced mass of their shot. Controlling for changes in mass, women’s shot put performance appears to decline to a greater extent than men’s, based on raw energy calculations. \u0000Conclusions: The double sigmoidal model detected a second-phase decline in shot put performances. We attribute this data feature to onset of improved drug testing protocols and a consequential reduction of doping. The assumption is that drug testing programs of shot putters has been successful and reduced the prevalence of drug taking in that sport. The application of a double sigmoidal model to historic performance statistics can be used to detect unknown interventions in analyses of sports performance.","PeriodicalId":17085,"journal":{"name":"Journal of Sports Medicine & Doping Studies","volume":"53 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2014-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85983224","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}
