Fast Strategies in Waiter-Client Games on KnK_n

Waiter-Client games are played on some hypergraph $(X,\mathcal{F})$, where $\mathcal{F}$ denotes the family of winning sets. For some bias $b$, during each round of such a game Waiter offers to Client $b+1$ elements of $X$, of which Client claims one for himself while the rest go to Waiter. Proceeding like this Waiter wins the game if she forces Client to claim all the elements of any winning set from $\mathcal{F}$. In this paper we study fast strategies for several Waiter-Client games played on the edge set of the complete graph, i.e. $X=E(K_n)$, in which the winning sets are perfect matchings, Hamilton cycles, pancyclic graphs, fixed spanning trees or factors of a given graph.Comment: 38 page

Pedro Jesús Ruiz-Montero,1 Alfonso Castillo-Rodriguez,2 Milena Mikalacki,3 Čokorilo Nebojsa,3 Darinka Korovljev31Department of Physical Education and Sport, Faculty of Physical Activity and Sport, University of Granada, Granada, Spain; 2Faculty of Sport, University of Pablo de Olavide, Seville, Spain; 3Faculty of Sport and Physical Education, University of Novi Sad, Novi Sad, SerbiaBackground: The purpose of this study was to examine the differences in anthropometric measurements using an aerobic and Pilates exercise program which lasted 24 weeks.Method: This was a clinical intervention study of 303 women over the age of 60 living in Novi Sad, Serbia. Changes in body mass index and skinfold thickness were estimated through height, weight, and anthropometric measurements. The program comprised Pilates exercises for upper- and lower-body strength, agility, and aerobic capacity.Results: Fat mass (FM) improved significantly (pre-test, 32.89%, 8.65; post-test, 28.25%, 6.58; P<0.01). Bone diameters and muscle perimeters showed no significant changes pre- and post-test (P>0.05), but there was a higher correlation between FM (%) and waist–hip ratio (rho, 0.80; P<0.01).Conclusion: A mixed program of aerobics and Pilates, controls and improves baseline muscle mass and decreases FM values, without causing deterioration during practice and follow-up exercises.Keywords: lean body mass, anthropometric measures, educative programA Letter to the Editor has been received and published for this article

Some characteristics of anthropological status of women in Novi Sad – Republic of Serbia

The aim of this study was to determine the anthropological status of adult females and the prevalence of females with potential health risk using the indices of obesity. The anthropological study was conducted from 2011 to 2013 in Novi Sad, (the north of Serbia). The tested group consisted of 310 women, with mean age 41.42±6.86, involved in the project "The impact of physical activity on the risk factors in the working population." Nutritional condition was determined using the body mass index (BMI kg/m2 ), while the waist circumference and WHR were used for assessing the central obesity. According to the average BMI, the younger females are predominantly with normal weight, while higher percent of older females is characterised with pre-obesity. In total, 45.85% of females are with excessive body weight, 34.62% of them being classified as overweight and 11.23% as obese. Central obesity is more frequent in older females aged up to 40. Potential health risk increases with age, and very high health risk from abdominal and overall obesity was observed in 6.25% of younger and 13,25% of older women. The data therefore point to the necessity of continuous monitoring and a combination of existing programs with other forms of organized physical activity
