(no author information available yet)
The female athlete triad is a medical condition observed in physically active females involving three components: 1) low energy availability with or without disordered eating, 2) menstrual dysfunction, and 3) low bone density. An individual does not need to show clinical manifestations of all three components of the female athlete triad simultaneously to be affected by the condition. Consequences of these clinical conditions may not be completely reversible, so prevention, early diagnosis, and intervention are critical...

Proietti, R, di Fronso, S, Pereira, LA, Bortoli, L, Robazza, C, Nakamura, FY, and Bertollo, M. Heart rate variability discriminates competitive levels in professional soccer players. J Strength Cond Res 31(6): 1719-1725, 2017-Heart rate variability (HRV) has been increasingly used to monitor team sports athletes. Besides the traditional time domain indices (i.e., the SD of successive RR intervals [SDNN] and the root mean square difference of successive normal RR intervals [RMSSD]), recently the use of the stress score (SS), which is an inverse function of the SD2 index derived from the Poincaré plot, and the sympathetic/parasympathetic ratio (S/PS) to monitor soccer players has been proposed...

REVIEW
Ryan P Nuccio, Kelly A Barnes, James M Carter, Lindsay B Baker
Sweat losses in team sports can be significant due to repeated bursts of high-intensity activity, as well as the large body size of athletes, equipment and uniform requirements, and environmental heat stress often present during training and competition. In this paper we aimed to: (1) describe sweat losses and fluid balance changes reported in team sport athletes, (2) review the literature assessing the impact of hypohydration on cognitive, technical, and physical performance in sports-specific studies, (3) briefly review the potential mechanisms by which hypohydration may impact team sport performance, and (4) discuss considerations for future directions...

Glazier's suggestion for the constraints-led approach as a GUT for sport performance is a worthy proposal. What is missing from these preliminary insights is a principled basis, in the form of pillars, for understanding the cornerstones of the sports medicine profession, and this lack of an overarching theoretical framework is also somewhat of a limitation in Glazier's initial ideas, as we argue later. Here we suggest that his preliminary proposal would benefit from considering a more comprehensive ontological positioning within the complexity sciences paradigm to benefit from conceptualising athletes and sports teams as complex adaptive systems...

Individual sport athletes have been shown to comprise unusually high proportions of morning-types (MTs) coupled with a higher prevalence of the morningness-associated PERIOD3 variable number tandem repeat (VNTR) allele, PER3(5). The degree to which type of sport selected is influenced by either chronotype or genotype, or the extent to which sporting environment contributes to chronotype is unclear. The aim of this study was to assess chronotype and PER3 VNTR polymorphism frequencies in team sport players and non-athletic controls...

Michael Visenio, Keely Buesing, Kody Moffatt
Pediatric solid organ lacerations are a relatively uncommon but potentially dangerous injury that must be addressed urgently once recognized. Seen most often during recreational or team sports, they usually occur after a blunt deceleration mechanism to the abdomen or flank. Depending on the severity of injury, solid organ laceration may not be immediately apparent clinically. This emphasizes the importance of sideline witnessing and evaluation, acting quickly once symptoms develop, and placing importance on safe sporting technique...

BACKGROUND: Medical illnesses and sports-related injuries both have an effect on athlete health and performance. Epidemiology of injury and illness has been extensively researched during international football tournaments and the European football season. Reports on injury location and severity differ across geographical regions, and there is limited information on injury epidemiology in African football leagues. No studies have investigated the illness burden in football in Africa. METHODS: This was a prospective cohort study involving two football teams over the 10- month duration of the 2015/16 Premier Soccer League in South Africa...

Studies have shown that attending to salient group relevant information could increase the BOLD activity across distributed neural networks. However, it is unclear how attending to group relevant information changes the functional connectivity across these networks. We investigated this issue combining resting states and task-based fMRI experiment. The task involved football fans learning associations between arbitrary geometric shapes and the badges of in-group, the rival and the neutral football teams. Upon learning, participants viewed different badge/shape pairs and their task was to judge whether the viewed pair was a match or a mismatch...

According to the stress-injury model (Williams & Andersen, 1998), personality factors predisposing athletes to elevated levels of stress may increase the risk of injury. As perfectionism has been associated with chronic stress, it may be one such personality factor. So far, however, no study has investigated the relationships between perfectionism and injury utilising a prospective design. Therefore, the present study examined perfectionistic strivings, perfectionistic concerns and injury in 80 junior athletes from team and individual sports (mean age 17...
