ObjectiveOur goal was to develop and validate a neurophysiological-centric baseline model that can be appreciated by the broader neuro community and practically utilized by the sports community.BackgroundAs concussions, a mild traumatic brain injury, and other traumatic brain injuries gain notoriety amongst public awareness, there has been a rise in available computer-based concussion baseline assessments. Furthermore, states, sporting agencies, and schools are mandating implementation of concussion baselines. However, validation and standardization of these current baseline neurological tests have been remiss and are often not utilized by medical or neurological practitioners, making their utility suspect.Design/MethodsWe applied our neurocognitive baseline program to college football freshmen and high school aged ice hockey players. The list of baseline assessments is: eye-hand coordination reaction time using the Dynavision D2™ device, stereopsis measurements, phoria, oculomotor performance, electroretinography and visual-evoked potential, binocularity, optical coherence tomography, peripheral vision assessments, and balance.ResultsThe results suggest that this baseline program can be performed as a battery appropriate for a pre-participation examination prior to sport participation. The data derived from said baseline can be interpreted by sport, age and gender specific. These demographics can also be examined for developing normative data and useful for identifying subjects outside this normal.ConclusionsIt is felt that the current state of concussion baselines for athletic organizations are inadequate. We chose to identify a series of baseline tests that are more clinically-relevant and easy to perform as evidenced from the pre-season baseline used by the University of Cincinnati athletes and non-collegiate athletes. These baselines are used as part of the standard pre-participation examination, further providing valuable insight into the development of sports vision training performance enhancement programs and extensively relied upon as a pre-season concussion baseline. We feel this model has enhanced clinical utility compared to the current wide spread computer-based neuropsychological assessments.

This study employed a turning point analysis to document events that influence the development of athletic identities in female athletes transitioning into high school. All participants ( N = 28), between the ages of 14–15 years old, belonged to a competitive club soccer team located in the southwestern United States. Through an analysis of pre- and post-season interviews and bi-weekly video journal entries, data revealed several fragmenting turning point events related to participants’ athletic identity development. These fragmenting turning points paired with the communication theory of identity (CTI) framework highlighted three identity gaps: (a) athletic-relational, (b) athletic-communal, and (c) athletic-enacted. Theoretical and practical implications are discussed regarding turning points in relation to athletic identity development and gender disparities in sport participation.

Advent of technology has caused growing interest in using computers to convert conventional paper and pencil-based testing (Henceforth PPT) into Computer-based testing (Henceforth CBT) in the field of education during last decades. This constant promulgation of computers to reshape the conventional tests into computerized format permeated the language assessment field in recent years. But, enjoying advantages of computers in language assessment raise the concerns of the effects that computerized mode of testing may have on CBT performance. Thus, this study investigated the score comparability of Vocabulary in Use test taken by 30 Iranian undergraduate students studying at a state university located in Chabahar region of Iran (CMU) to see whether scores from two administrations of testing mode were different. Therefore, two similar tests were administered to the male and female participants on two testing mode occasions with four weeks interval. Employing One-Way ANOVA statistical test to compare the mean scores and Pearson Correlation test to find the relationship between mode preference and performance revealed that two sets of scores were not different and gender difference was not also considered a variable that might affect performance on CBT. Based on the results, computerized version of the test can be considered a favorable alternative for the state undergraduate students in Iran.

Purpose of this study was to compare effects of general strength training with combined maximal strength and plyometrics training. Twelve young ice hockey players were examined and intervened 4-week general strength training (EX1) at first and consequently 4-week, combined training (EX2). Combined training consisted of maximal strength workouts with 2-4 repetitions on 85-95% 1RM and subsequent application of plyometrics workouts with 6-10 repetitions. The training group performed 2 sessions per a week in 3 sets of exercises. The measurements were assessed before, between and after periods and consisted of specific test performed on ice and non-specific tests off ice. The results showed that in EX2 period SJ improved from 33,3 ± 2,89 cm to 34,35 ± 2,80 cm by 1,05 cm (3,2%; p<0,01); CMJ from 36,51 ± 4,39 cm to 37,84 ± 4,36 cm by 1,33 cm (3,6%; p<0,01). Also in EX1 period SJ was changed from 32,48 ± 3,65 cm to 33,3 ± 2,89 cm (p<0,05). Anaerobic alacticpower (AAV) changed significantly in EX1 period from 42,09 ± 4,48 W.kg-1 to 42,72 ± 4,61 W.kg-1 (p<0,01) afterwards in EX2 period to 43,78 ± 4,44 W.kg-1 (p<0,01). In jumping performances we measured in both periods significant improvements; standing long jump (SZM) in EX1 period from 246,25 ± 11,07 cm to 249,17 ± 10,32 cm (p<0,01) then in the end of EX2 period 253,58 ± 9,83 cm (p<0,01). Standing triple jump (3SK), agility run (10x5) and all specific test on ice were significant changes recorded only in EX2 period. 3SK from 722,42 ± 29,58 cm to 727,50 ± 30,64 cm; 10x5m from 17,00 ± 0,57 s to16,90 ± 0,57 s (p<0,01); on ice speed tests (1x36m) from 4,95 ± 0,10 s to 4,88 ± 0,09 s by 1,4% (p<0,01); (6x9m) from 13,73 ± 0,48 s to 13,63 ± 0,51 s by 0,8% (p<0,05); in speed endurance ice hockey skating test (Okr) form 14,79 ± 0,18 s to 14,67 ± 0,20 s o 0,8% (p<0,05). Skills ice hockey test parameters (Sla) did not changed significantly in EX1 neither in EX2 period. It could be concluded that both periods had effect on motor performance enhancement, but EX2 training period was more sufficient for improvement in speed-strength abilities especially in specific condition on ice.

Alpha-stimulating neurobiofeedback is actively introduced into sports training. Successful training contributes to optimal functioning and sports performance enhancement. However, not all athletes are able to achieve their goals. The main problem is the absence of the data explaining the effect of sports qualification, specialization, and gender on successful neurobiofeedback. Aim. The article deals with establishing the correlation between sports qualification, specialization (depending on movement character), gender, and successful neurobiofeedback. Materials and methods. 216 athletes (124 males and 92 females) participated in a 15-day neurobiofeedback course with the Boslab-alpha equipment (Russia). The average age of participants is 19 ± 0.1 years. All participants have 5 or more years of sports experience. All athletes provided their written informed consent for participation in the study. The 25–30-minute sessions of neurobiofeedback were conducted once per day. The electrodes were set up in the frontal and parietal area in a bipolar mode according to the 10–20 international system (F1 and P3). The increase in the spectrum power of alpha range by no less than 10 % compared to the previous session was considered as successful neurobiofeedback. We calculated the percentage of successful and unsuccessful training sessions for each participant. Statistical analysis of the data obtained was performed with the help of SPSS 13.0 software. Results. The study of successful training in athletes divided into groups in terms of gender, sports qualification, and sports specialization did not reveal any statistically significant differences. By using multifactor dispersion analysis, it was established that successful neurobiofeedback in athletes depended on all the abovementioned factors (F = 2.780; P < 0.05). Conclusion. Successful neurobiofeedback in athletes is determined by the combination of three factors (gender, sports specialization, sports qualification), which do not possess significant effect when studied separately.

The Impact

Relative age differences can lead to varying sport participation opportunities; however, scant research has focused on the impact of relative age on experiences within sport. This study explored if youth developmental experiences differed by relative age among competitive female ice hockey players. Players within Ontario (n = 264) completed an online survey that contained the Youth Experience Survey for Sport (YES-S) along with additional demographic questions. The YES-S measures 5 dimensions of positive (i.e., personal and social skills, cognitive skills, goal setting, and initiative) and negative developmental experiences in sport. The results of the multivariate analysis of variance (MANOVA) suggested that the developmental experiences reported by athletes did not differ across birth quartiles (Wilks’ Lambda = 0.940, F (15, 707.105) = 1.061, p = .390). Although there was a relative age effect (RAE) trend within this sample of competitive female ice hockey players, the differences across birth quartiles were not statistically significant. It appears that relative age does not result in youth having different positive and negative sporting experiences. Exploring the characteristics of sport environments (e.g., coaches, practices) and personality traits of competitive athletes to better understand how relatively younger athletes continue their participation in sport despite being at a perceived disadvantage warrants further investigation.

And Gender

Most of the concussion literature is devoted to concussion and men, and this literature focuses primarily on American football and ice hockey. Yet women appear to be more prone to sport-related concussion than men, and may manifest with more concussion-like symptoms both at both baseline and post-concussion. There may be both endocrinologic and biomechanical reasons why women’s concussive symptoms are different from men’s, but this remains incompletely understood. There may also be sex-based and gender-based differences in how men and women experience and describe concussion. It is important to understand these distinctions when managing concussion in women.

In this case study, learners are introduced to Sloane, a diversity and inclusion officer who is working to create more inclusive sport and recreation opportunities in her community. A national-level sport event will be hosted in her community and provides an opportunity to elevate and accelerate the work she is already doing with sport and recreation organizations. Learners will develop an understanding of two key themes: LGBTQ2+ inclusion and event leveraging. Working through the case will require learners to think critically about sexuality and gender identity in the context of sport participation and organizations. Furthermore, learners will have the opportunity to think creatively about how they can support innovation in organizational cultures and practices with a view to fostering more inclusive, welcoming, and safe sport organizations.

The design of engineering systems involves the design of dependent subsystems and the integration of these into a whole. A typical system has the characteristics of being multileveled, multidimensional, and multidisciplined in nature. It is this complexity which causes problems for the designer in making well-founded decisions. A decision support technique has been developed which offers a structured facility for the design of the subsystems and for the modeling of the interaction which is present between subsystems. The method, employing optimization procedures, allows all aspects of the system design to be considered concurrently, to produce the "best" solution, as defined by the specifications. This is in contrast to the traditional design method, which is iterative and cyclic in nature, involving sequential reevaluation and refinement. In this paper, the effectiveness and efficiency of the decision support problem approach is demonstrated using the hierarchical characteristics of a design for a barge. The barge problem, though basic in form, is comprehensive in concept and tutorial in nature. As a formulation for "system" optimization, it uses a computer-based method for solution and illustrates the virtues of a multilevel/multidisciplinary approach to design and decision-making. It also exhibits the same characteristics and provides valuable insight into the solution of the more complex problems encountered in practical ship design.
