Rational secret sharing was proposed by Halpern and Teague in [12]. The authors show that, in a setting with rational players, secret sharing and multiparty computation are only possible if the actual secret reconstruction round remains unknown to the players. All the subsequent works use a similar approach with different assumptions. We change the direction by bridging cryptography, game theor...

BACKGROUND Anterior cruciate ligament (ACL) rupture is a significant injury in National Basketball Association (NBA) players. HYPOTHESES NBA players undergoing ACL reconstruction (ACLR) have high rates of return to sport (RTS), with RTS the season following surgery, no difference in performance between pre- and postsurgery, and no difference in RTS rate or performance between cases (ACLR) and...

Exercise training may increase production of free radicals and reactive oxygen species in different ways. The training type and intensity may influence free radicals production, which leads to differences in oxidative stress status between athletes, but the results of the previous studies are incosistent. The aim of our study was to estimate oxidative stress status in elite athletes engaged in ...

OBJECTIVES To investigate if ligamentous laxity increases seasonal incidence of injury in male first division club rugby players, and to determine if strength protects against injury in hypermobile and tight players. METHODS Fifty one male first division club rugby players were examined for ligamentous laxity using the Beighton-Horan assessment and graded with an overall laxity score ranging ...

This article presents the results of a case--control study regarding the background to handball injuries among players of 12 years and older. Data were collected by means of a written questionnaire on the nature, location and direct causes of the injuries as well as information on risk factors. Injured players (n = 130) are compared with non-injured players (n = 512). The response for the cases...

analyzing free riding problem through static games considering homogenous players has been resulted in choosing the free riding strategy as a dominant strategy for the players. in this paper free riding is analyzed through cooperation game imposing non-homogenous players using network models. players would be differentiated by their links with their neighbors in the game. evolutionary game theo...

During a 1-year period 100 badminton players were registered and treated in the casualty ward of Randers City Hospital, Denmark. The injuries to the badminton players constituted 5% of all sports injuries registered during the same period in the casualty ward. At follow-up questionnaires were sent to all participants. Replies were received from 89 patients. Over the same period all sports parti...

BACKGROUND Heart rate variability (HRV) can disclose the specific adaptation of sympathovagal modulation to exercise. This study investigated the change in HRV measures after anaerobic and aerobic intermittent exercises in university football and futsal players. METHOD 36 male university students with physically active lifestyle (n=14), football (n=12), and futsal (n=10) participated in this ...

OBJECTIVE The digit representations in area 3b were studied to examine whether there is training-dependent reorganization in string players. METHODS Somatosensory evoked magnetic fields were recorded following electrical stimulation of digits 1 (D1), 2 (D2) and 5 (D5) of both hands in 8 string players and of the left hand in 12 control subjects. The N20m and P30m responses, and high-frequency...

This case study evaluated the response of objective and subjective markers of overreaching to a highly demanding conditioning training mesocycle in elite tennis players to determine 1) whether players would become functionally or non-functionally overreached, and 2) to explore how coherently overreaching markers would respond. Performance, laboratory and cardiac autonomous activity markers were...
