Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique that modulates cortical excitability. It is devoid of serious adverse events and exerts variable effects on cognition, with several research findings suggesting that it can improve memory, verbal and mathematical skills. Because tDCS devices are low-cost, portable and relatively easy to assemble, they have become available outside of the medical setting and used for non-medical ("cosmetic") purposes by laypersons. In this sense, tDCS has become a popular technique aiming to improve cognition and the achievement of a better performance not only at work, but also in other fields such as sports, leisure activities (video games) and even the military...

INTRODUCTION: Pelvic apophyseal avulsion can limit young athletes' performance for months and may result in permanent disability. Nonoperative treatment is most commonly preferred, while surgical management with reduction and fixation is reserved for selected cases. Our aim was to evaluate outcomes of operative management of pelvic apophyseal avulsions in a series of adolescents and young adult athletes. MATERIALS AND METHODS: Operative room registries and medical records were reviewed to identify patients who received surgical treatment for pelvic apophyseal avulsions who were younger than 24 years and with a minimum of 12 month follow-up...

Background: Pre-operative quadriceps strength may have a positive influence on post-operative function and outcomes at time of return to sport. Little consideration has been given to quadriceps strength during the early post-operative timeframes. Twelve-week post-operative anterior cruciate ligament reconstruction (ACL-R) is considered a critical time point for progression in the rehabilitation process. There is currently limited research looking at the relationship between clinical measurements pre-operatively and at 12-weeks following ACL-R...

Cristiano Eirale, Scott Gillogly, Gurcharan Singh, Karim Chamari
Soccer is the most popular sport in the world. While injuries and illnesses can affect the players' health and performance, they can also have a major economic impact on teams. Moreover, several studies have shown the favourable association between higher player availability and team success. Therefore, injury prevention could directly impact clubs' financial balance and teams' performance via increased player availability. To be able to develop effective methods of injury prevention, it is vital to first determine the scope and the degree of the problem: the mechanisms and types of injuries, their frequency and severity, etc...

In addition to different injuries, infections are the most common reason for giving up training altogether or reducing its volume and intensity, as well as a lack of opportunities to participate in sports competitions. Nowadays, a slow but constant re-emergence of pertussis, especially among teenagers and young adults, including athletes, can be observed. This paper describes an outbreak of pertussis among professional Polish shooters, focusing on the transmission of Bordetella pertussis infection between members of the national team, its influence on performance capacity and adverse event analysis...

OBJECTIVES: Overtraining syndrome (OTS) leads to worsened sports performance and fatigue. The pathophysiology of OTS has not been entirely elucidated, and there is a lack of accurate markers for its diagnosis. Changes in hormonal responses implicated in OTS were stimulated by exercise, which has limited their interpretation. Hence, we aimed to evaluate growth hormone (GH) and prolactin responses to a gold-standard and exercise-independent stimulation test, the insulin tolerance test (ITT)...

The practice of sport and medium-high intensity exercise increases the needs of energy and nutrients. Proper nutrition is very important for reaching the maximum performance, reducing the risk of injury, and ensuring the best recovery. It must also ensure the achievement of optimum nutritional status and prevent health problems at the present and in the future time. Eggs are a very nutritious food that can help athletes to achieve a correct diet. It contains proteins of high quality and bioavailability, a profile of fatty acids very favorable from the cardiovascular point of view, and vitamins and minerals involved in energy and protein metabolism, in defense against oxidative stress and inflammation, in cell growth and tissue repair...

In all countries life expectancy is rising, and many older persons spend a longer period in good health. Nevertheless, frailty is present in older people and can be considered as a risk factor for limitations. The "German Health Interview and Examination Survey for Adults" (DEGS1) 2008 - 2011 comprised interviews, examinations and tests. Data on 1110 community-dwelling people aged 70 to 79 years participating in DEGS1 with full records on frailty were analysed. Physical frailty was defined as exhaustion (SF-36 item), low grip strength, slowness (Timed Up-and-Go test > 15 seconds or unable to perform) and low physical activity (no sports or exertion)...
