#1
Nicole Fawcett, Hannah Gibson, Sam Abraham
A comprehensive review of the literature was completed to investigate college student-athletes' perceptions regarding the long-term effects of concussions. Based on the findings, it was determined that there is a need for more education among student-athletes regarding this topic. This was a quantitative, cross-sectional, nonexperimental study with a descriptive design. A survey with 7 demographic and 17 Likert-type statements was collected from 100 student-athletes in a Midwestern college at their specified team practice sites for data collection...

To visually perceive opportunities for action, athletes rely on the movements of their eyes, head and body to explore their surrounding environment. To date, the specific types of technology and their efficacy for assessing the exploration behaviours of association footballers have not been systematically reviewed. This review aimed to synthesise the visual perception and exploration behaviours of footballers according to the task constraints, action requirements of the experimental task, and level of expertise of the athlete, in the context of the technology used to quantify the visual perception and exploration behaviours of footballers...

Enda F Whyte, Chris Richter, Siobhan O'connor, Kieran A Moran
We investigated the effects of high intensity, intermittent exercise (HIIP) and anticipation on trunk, pelvic and lower limb biomechanics during a crossover cutting manoeuvre. Twenty-eight male, varsity athletes performed crossover cutting manoeuvres in anticipated and unanticipated conditions pre- and post-HIIP. Kinematic and kinetic variables were captured using a motion analysis system. Statistical parametric mapping (repeated-measures ANOVA) was used to identify differences in biomechanical patterns. Results demonstrated that both unanticipation and fatigue (HIIP) altered the biomechanics of the crossover cutting manoeuvre, whereas no interactions effects were observed...

CONTEXT:   Athletic training facilities have been described in terms of general design concepts and from operational perspectives. However, the size and scope of athletic training facilities, along with staffing at different levels of intercollegiate competition, have not been quantified. OBJECTIVE:   To define the size and scope of athletic training facilities and staffing levels at various levels of intercollegiate competition. To determine if differences existed in facilities (eg, number of facilities, size of facilities) and staffing (eg, full time, part time) based on the level of intercollegiate competition...

CONTEXT:   After a concussion or mild traumatic brain injury (mTBI), patients often suffer from light sensitivity, or photophobia, which contributes to decreased quality of life post-mTBI. Whereas sunglasses may provide some relief from photophobia, they are not practical indoors or in low light. A light-mitigation strategy that can be easily used indoors as needed to optimize the relief. We have found that many photophobic patients experience relief using colored sunglasses. OBJECTIVE:   To provide the athletic trainer with a means and method to assess whether an athlete is suffering from photophobia after concussion and to determine if colored glasses provide relief...

OBJECTIVE To evaluate clinical and tenoscopic findings in a large group of horses undergoing surgery of the carpal flexor sheath (CFS) and determine whether any of the presurgical clinical signs were associated with tenoscopic findings. ANIMALS 242 horses that had undergone diagnostic and therapeutic tenoscopy of the CFS because of aseptic tenosynovitis. PROCEDURES Medical and tenoscopic video records (when available) of 242 horses undergoing tenoscopy of the CFS at a single equine clinic between January 2005 and June 2014 were reviewed...

We investigated the relationships between the biomechanics of the double poling (DP) technique in cross-country skiing, its economy and athletes' skill. To this aim, skiers' motion has been factorized into components through principal component analysis (PCA).Eight high-level (HL) and eight regional level (RL) male cross-country skiers performed a 5-min submaximal DP trial while roller skiing on a treadmill at 14 km h(-1) and 2° incline. Whole-body kinematics was recorded with a motion capture system. PCA was applied to markers coordinates to extract principal movements (PMk ), which were ranked by their variance...

Surashree Sen Gupta, Mahua Ghosh
Octacosanol is a lesser known nutraceutical with the potential for treatment of several inflammatory diseases, high cholesterol, Parkinson's symptoms and tumour growth along with the capacity to improve athletic performance. But its lipophilicity and large structure inhibits extended solubility in water resulting in poor absorption and a low bioavailability. In the present work, sodium salt of octacosyl sulfate was synthesized. It displayed improved water solubility. Its nanocrystals, synthesized by means of nanoprecipitation technique, enhanced diffusion velocity, antioxidant capacity, shelf-life, penetrability and bioavailability...

OBJECTIVE: Muscle strength imbalance in the shoulder region can be considered as a predisposing factor in the development of movement dysfunctions, possibly leading to overuse injuries. Repetitive overhead throwing, performed in sports, may result in muscle imbalance between the external (ER) and internal (IR) rotators. Muscle strength measured with an isokinetic device, is reported as a concentric (CON) or eccentric (ECC) force. The balance between an agonist and an antagonist is mentioned as a ratio (CON/CON or ECC/CON)...

Lew Hardy, Matthew Barlow, Lynne Evans, Tim Rees, Tim Woodman, Chelsea Warr
Hardy et al. (2017) reported the findings of a large-scale, multisource, qualitative study that examined the commonalities of, and discriminators between, a group of super-elite (SE) and a group of elite (E) athletes who were matched on gender, sport, discipline, and era. Fifteen research teams who are actively engaged in research in the domain then provided critical commentaries on the target paper. In our response to these commentaries, we briefly remind the reader of the primary findings of the original paper and then deal with the commentaries under the subheadings: Necessary and Sufficient Conditions for Elite Performance; Mediating and Moderating Variables; Methodological Issues; Omissions; and Alternative Approaches...

Tristan J Coulter, Clifford J Mallett, Jefferson A Singer
Using a life story approach, Hardy and colleagues present a study examining the similarities and differences in the psychosocial development of UK-based elite and super-elite athletes. We found this work to be a highly personal account into the lives of these cohorts, which advances knowledge concerning the psychology and influencing events and circumstances that separate the good from the great performers. We make some suggestions for how to enrich the study's findings and approach, by (1) adopting McAdams' multilayer framework of personality, as an overarching structure for assessing the whole person, and (2) encouraging the authors to explore the narrative structure of the presented life stories and go beyond simply an interpretation of their content...

Tim Buszard, Rich S W Masters
A culture of striving was notable in the developmental background of many of the elite and super elite athletes in the Hardy et al. STUDY: Critically, a culture of striving was credited with a positive influence on a range of issues relevant to elite sports performance, including performance under pressure. Of the six athletes who did not reveal a culture of striving, five reported the greatest difficulty performing in high-pressure situations. We suspect that a culture of striving facilitates the development of attention control ability, which subsequently assists performance under pressure...

This commentary on Hardy and colleagues' discussion of psychosocial biographies of British super-elite athletes discusses cultural differences from a Chinese perspective. While British super-elite athletes might cope with high pressure by a counter-phobic attitude or total preparation, Chinese super-elite athletes achieve that by "Pingchangxin," a concept originated from Hongzhou Buddhism. This concept is difficult to translate but includes having no evaluation of good and evil, maintaining a peaceful mind in adversity and frustration, letting nature take its course, so as to reach the realm of freedom...

Tynke Toering
The target article describes an interesting study, which provides some challenging findings regarding athletes' pathway to excellence. The suggested links between critical life events, need for success, personal characteristics, and eventual performance level make sense from a psychodynamic perspective. This commentary will discuss some critical points related to the application of the findings in talent identification and -development programs. These are (1) the possible effect of the selection of participants on the results (including the impact of dependence on others for team sport athletes and the opportunity for multiple medal attainment), (2) a lack of detail in the description of how the athletes approached the critical life events (the perception of an event may contribute more to development than the event itself), and (3) a lack of detail in the description of the practice process throughout development...

We consider the data reported in the target article with respect to key motivational frameworks and characteristics, including grit and self-determined forms of motivation. Empirical data are reviewed that highlight the relationships between these concepts and practice and success. We highlight the concept of grit as a defining characteristic of the super-elite athletes, in reference to both their continued perseverance in the face of obstacles, as well as the increased motivation seemingly caused by such obstacles or setbacks...

Super-elite athletes succeed in part because: (a) previous hardship builds resilience, (b) success breeds success, and (c) they can rename anxiety as excitement. It is unlikely that most of their outstanding success is due to psychodynamic compensatory mechanisms.

Athletes devote their lives to practicing their chosen sport so as to attain the highest level of skilled performance. A perennial question is why are some athletes better than others? Most debates on this issue reduce to genetics (natural abilities) vs differences in accumulated deliberative practice. In contrast, the target article under discussion here reports on a study that identified psychosocial factors (obsessiveness, ruthlessness) and early life experiences (trauma or loss) that distinguished those athletes at the Olympics and World Championships that medaled over those that did not...
