Athletic Pubalgia and "Sports Hernia" Optimal MR Imaging Technique and Findings
Iranian Journal of Radiology , 2009,
Abstract: "nGroin injuries are common in athletes who participate in sports that require twisting at the waist, sudden and sharp changes in direction, and side-to-side ambulation. Such injuries frequently lead to debilitating pain and lost playing time, and they may be difficult to diagnose. Diagnostic confusion often arises from the complex anatomy and biomechanics of the public symphysis region, the large number of potential sources of groin pain, and the similarity of symptoms in athletes with different types or sites of injury. Many athletes with a diagnosis of "sports hernia" or "athletic pubalgia" have a spectrum of related pathologic conditions resulting from musculotendinous injuries and subsequent instability of the public symphysis without any finding of inguinal hernia at physical examination. The actual causal mechanisms of athletic pubalgia are poorly understood, and imaging studies have been deemed inadequate or unhelpful for clarification. However, a large-field-of-view magnetic resonance (MR) imaging survey of the pelvis, combined with high-resolution MR imaging of the public symphysis, is an excellent means of assessing various causes of athletic pubalgia, providing information about the location of injury, and delineating the severity of the disease. Familiarity with the pubis anatomy and with MR imaging findings in athletic pubalgia and other confounding causes of groin pain allows accurate imaging-based diagnoses and helps in planning the treatment that targets specific pathologic conditions.

Sports Medicine, Arthroscopy, Rehabilitation, Therapy & Technology , 2009, DOI: 10.1186/1758-2555-1-16
Abstract: This study performed as a cross-sectional study. All elite Iranian female athletes of 34 sports federation, including female athletes in national teams and medalists of Tehran were invited to participate. A total of 788 (95% response rate) returned the questionnaires and were examined. Younger athletes under the age of menarche were excluded. Each athlete completed a self-administered questionnaire, which covered the following questions about participant's demographic information, athletic history, history of injuries and menstrual pattern. In order to diagnose the causes of amenorrhea/Oligomenorrhea including polycystic ovary syndrome(PCOS), participants with amenorrhea/Oligomenorrhea underwent further investigation. They were evaluated by following Para clinic investigation, and an ultrasonographic study of ovary.The age ranged from 13–37 (mean = 21.1, SD = 4.5). Seventy one (9.0%) individuals had amenorrhea/oligomenorrhea, among those, 11 (15.5%) had PCOS.There was also a positive association between amenorrhea/oligomenorrhea and the following: age under 20 OR; 2.67, 95%CI(1.47 – 4.85), weight class sports OR; 2.09, 95%CI(1.15 – 3.82), endurance sports OR; 2.89, 95%CI(1.22 – 6.84), late onset of menarche OR; 3.32 95%CI(1.04–10.51), and use of oral contraceptive pills OR; 6.17, 95%CI(3.00 – 12.69). Intensity of training sport or BMI were not risk factors.These findings support the previous findings in the literature that the prevalence of amenorrhea/oligomenorrhea is high in athletes. Furthermore, we provided the first report on the prevalence of PCOS in female athletes with amenorrhea/oligomenorrhea. Athletes would be greatly benefited by greater general awareness about the complications of amenorrhea/oligomenorrhea.To increase awareness of exercise-associated menstrual cycle irregularities, it is necessary to design complete and comprehensive education programs for female athletes, their parents, their coaches, and the relevant authorities.Menstrual disorders su

Brazilian Oral Research , 2004, DOI: 10.1590/S1806-83242004000400004
Abstract: the aim of the present study was to evaluate the efficacy of manual and electric toothbrushes in plaque control in periodontal patients after proper instructions. thirty six periodontal patients (mean age of 49 years, 21 females and 15 males) were included and completed the study (100% compliance). a single-blinded, randomized, controlled, cross-over clinical design was adopted, with the patients using during 2 periods of 14 days each the manual and/or electric toothbrush. four subgroups of 9 individuals were studied: a1 - used manual toothbrush in both experimental periods; a2 - used the manual toothbrush during the first period and the electrical toothbrush during the second period; b1 - used electrical toothbrush during both periods; b2 - used the electrical toothbrush in the first period and the manual one in the second period. brushing was performed during 14 days and at day 14 and 28 it was performed in the clinic, and timing of brushing was recorded without patients being aware. the plaque index (silness, l?e, 1964) was used. intra-group comparisons were performed by paired t-test and inter-group comparisons by independent sample t-test, with an alpha level of 0.05. the results showed no difference between the tested brushes neither for plaque nor for timing. however, re-instruction was detected as an important factor, since for all groups the second period, after reinstruction, showed lower plaque scores. it is concluded that professional advice and instruction and re-instruction seem more important in order to obtain good plaque control than the choice of toothbrush in subjects with periodontal disease.
MOTIVATIONAL MEASURE OF THE INSTRUCTION COMPARED: Instruction Based on the ARCS Motivation Theory V.S. Traditional Instruction in Blended Courses

The Turkish Online Journal of Distance Education , 2010,
Abstract: The ARCS Motivation Theory was proposed to guide instructional designers and teachers who develop their own instruction to integrate motivational design strategies into the instruction. There is a lack of literature supporting the idea that instruction for blended courses if designed based on the ARCS Motivation Theory provides different experiences for learners in terms of motivation than instruction developed following the standard instructional design procedure for blended courses. This study was conducted to compare the students’ motivational evaluation of blended course modules developed based on the ARCS Motivation Theory and students’ motivational evaluation of blended course modules developed following the standard instructional design procedure. Randomly assigned fifty junior undergraduate students studying at the department of Turkish Language and Literature participated in the study. Motivation Measure for the Blended Course Instruction (MMBCI) instrument was used to collect data for the study after the Confirmatory Factor Analysis (CFA). Results of the study indicated that designing instruction in blended courses based on the ARCS Motivation Theory provides more motivational benefits for students and consequently contributes student learning.
The Effectiveness of Web-Based Instruction: An Initial Inquiry
Tatana M. Olson,Robert A. Wisher
International Review of Research in Open and Distance Learning , 2002,
Abstract: As the use of Web-based instruction increases in the educational and training domains, many people have recognized the importance of evaluating its effects on student outcomes such as learning, performance, and satisfaction. Often, these results are compared to those of conventional classroom instruction in order to determine which method is “better.” However, major differences in technology and presentation rather than instructional content can obscure the true relationship between Web-based instruction and these outcomes. Computer-based instruction (CBI), with more features similar to Web-based instruction, may be a more appropriate benchmark than conventional classroom instruction. Furthermore, there is little consensus as to what variables should be examined or what measures of learning are the most appropriate, making comparisons between studies difficult and inconclusive. In this article, we review the historical findings of CBI as an appropriate benchmark to Web-based instruction. In addition, we review 47 reports of evaluations of Web-based courses in higher education published between 1996 and 2002. A tabulation of the documented findings into eight characteristics is offered, along with our assessments of the experimental designs, effect sizes, and the degree to which the evaluations incorporated features unique to Web-based instruction.
Athletic Scholarships and the Politics of Child Rearing in Canada  [PDF]
Noel Dyck
Anthropological Notebooks , 2006, DOI: 1234567
Abstract: Organized competitive community sports for children and youth have become popular activities in contemporary Canadian society and are eagerly supported by many parents who view these as socially appropriate pastimes for sons and daughters. Children’s achievement of athletic success tends to be viewed by many parents as a sign of their relative preparedness to confront and manage the future social and economic challenges of adulthood. Athletic success at different levels is also taken to demonstrate the adequacy of parents’ attempts to attend appropriately to the responsibilities of child rearing. This essay examines the particular attractions provided by the possibility of athletically accomplished children eventually winning paid athletic scholarships to attend colleges and universities in the United States. The paper asks why so many middle-class parents who are able to afford the cost of underwriting post-secondary education for sons and daughters nonetheless commit so much of their own time and resources, not to mention those of their children, to the pursuit of athletic scholarships in the USA.

Research Journal of Applied Sciences, Engineering and Technology , 2013,
Abstract: Many researches have show that sports play a significant role in increasing the social adaptability of mentally challenged children. Because people’s social adaptability is impacted by multiple factors and its mechanism of action is very complicated, based on the genetic neural network, this study used the genetic algorithm to improve the method and study the impact of sports on the basic athletic ability, language ability, social skills and working ability of mentally challenged children. We conclude that it bears important significance to study the impact of sports on the social adaptability of mentally challenged children.
Prediction and Quantification of Individual Athletic Performance  [PDF]

Statistics , 2015,
Abstract: We provide scientific foundations for athletic performance prediction on an individual level, exposing the phenomenology of individual athletic running performance in the form of a low-rank model dominated by an individual power law. We present, evaluate, and compare a selection of methods for prediction of individual running performance, including our own, \emph{local matrix completion} (LMC), which we show to perform best. We also show that many documented phenomena in quantitative sports science, such as the form of scoring tables, the success of existing prediction methods including Riegel's formula, the Purdy points scheme, the power law for world records performances and the broken power law for world record speeds may be explained on the basis of our findings in a unified way.
