Background. It is known that at present in the volleyball game there is no perfect balance between the moments of attack and defense, the latter having a significant role in victory. The more frequent the sequence of the two, the more the game becomes attractive and spectacular. Attacking moments must be completed by a winning point; their failure can cause disruption in the team's mechanism, with further significant consequences, especially when they occur repeatedly. Aims. We believe that by using specially designed methods, based on attention training, we could improve the percentage of successful attacking shots; by alternating forceful attacking moves with placed ones, a state of uncertainty will be created in the defending team's game and the possession of the ball will be altered. Methods. The research study was conducted with two women's volleyball teams, similar in value, playing in the North series of the A2 Republican championship: the experimental group 1 (n=12), which followed an attention training program aimed at improving the efficiency of a placed attacking shot (CSU LPS Oradea), and the control group 2 (n=12), which followed a traditional training program (CNE CSS Baia Mare). To improve attention training we used a number of ten exercises that are part of a complex technical and tactical training. To quantify the results we used SPSS 17.0, mixed ANOVA, Student test for independent and paired samples, and, for assessing placed attacking shots, the so-called composite index. Results. The data regarding the evolution of the placed attacking shot that was subject to this analysis show the improvement of the value of this method of attack as a trend for the experimental group (Lap 1=.069) and (Lap 2=.067), which means that our intervention favors improvements in placed attacking shots, as compared with the control group whose evolution was in the normal range for this game action, and followed the traditional training method. Conclusions. If the index of significance of the difference of averages between the two evaluation moments for Lap 1 and Lap 2 are in the trending level just for the experimental group, a continuation of this study through a longer term approach of this attention method or through a restructuring of the exercise included in the intervention program should be considered.

Background. The authors present the relationship between specific means and parameters of effort in performance weightlifters' training. Ensuring an optimum relationship of technical, physical training means and effort parameters during training sessions have proved to lead to better performances achieved in competition. This approach entailed the organization of a study within the Weightlifting Olympic Team. Goals. The scientific argument is the presentation of the specific means used in performance weightlifters' training in the competitive period which, by providing an optimum relationship of technical and physical training and effort parameters during workouts, contribute to the increase of athletic performances in competition. Methods. The study was conducted throughout a mezzo-cycle of competitive training (2.03.09-12.04.09) formed of 6 micro-cycles, applied to a group of 6 senior athletes, 20 to 24 years old. We monitored athletes' evolution in the competitive period, during workouts and contest. Statistical processing was performed with Word and "KyPlot" programs. Results. The study emphasizes the relation of specific means and effort parameters in the pre-competitive mezzo-cycle of performance weightlifting. The review of training specific means shared in a competitive mezzo-cycle revealed a gradual decrease of reps number in each training micro-cycle. In terms of training means shareed within the competitive mezzo-cycle, an average of 43.4% at technical training and 56.6%, at physical training was evidenced. The review of performances achieved in competition by the subjects of the study in the European Championships for Se-niors - Bucharest highlighted the participation of 6 senior athletes, whose best performances were the 2nd place at snatch lift, 4th place at clean and jerk and 5th place total lifts, won by the athlete MN, 69 kg class. Conclusions. Effort intensity throughout a competitive training micro-cycle emphasizes the variability of parameters in terms of loads volume during workouts and the intensity of training means application.

Physical activity represents an important component of a healthy lifestyle, which contributes to the enhancement of the quality of life and to one's personal well being. This paper represents a review of the scientific literature regarding physical activity and health, taking into account the advantages of physical activity, the risks of a sedentary lifestyle and the factors which impede an active lifestyle. In the second part some recommendations are presented regarding the modification of the school curriculum with the purpose of developing healthy attitudes towards physical activity.

Background. CoQ10 is a vitamin-like compound with a role in the mithochondrial transport chain and also is an antioxidant. Aims. We followed the influence of Co Q10 supplement on the aerobic and anaerobic exercise capacity in athletes. Methods. The research compared two groups of soccer players (n=10) 19 to 20 years old. Group I was the control group and athletes from group II were suplemented with 30 mg of CoQ10 daily. The indicators for the research were the aerobic capacity and anaerobic exercise capacities. Results. The maximum O2 intake increased in both groups; CoQ10 supplement has no significant effects over the maximal consumption of O2. The maximum aerobic power increased in both groups, and were significantly higher after supplementation. The maximum anaerobic power increased in both groups but the supplementation did not have significant effects. Conclusions. CoQ10 suplementation increases maximum aerobic power in young trained soccer players. [ABSTRACT FROM AUTHOR]

In the game of basketball shooting goals is the technical component through which the purpose of the game, scoring points, is accomplished. Taking into account its importance, shooting is studied from the point of view of many scientific disciplines. Starting from the premise that the ball trajectory after shooting is identical to the movement of a projectile launched obliquely, the paper aims to develop a mathematical model of shooting, taking into account the launching angle, speed, flight, and the drop angle of the ball in the basket. In this approach an abstraction of the influence of air resistance on the ball was made. The mathematical model described can be used to study the dynamics parameters of shooting with the aim of deepening knowledge and improving the mechanism of the implementation of this process.
