To evaluate the foot, the Foot Posture Index-6 (FPI 6) was used, while the posture of the calcaneus and the tibia was analyzed using the Global Postural System 400. The statistical results indicate strong intensity links between flat foot and the frontal alignment of the calcaneus and the tibia, as follows: FPI 6 right foot score and calcaneus - right foot angle (r= 0.824; p < 0.001), tibia - right foot angle (r= 0.588; p < 0.001); FPI 6 left foot score and calcaneus - left foot angle (r= 0.824; p < 0.001), tibia - left foot angle (r= 0.853; p < 0.001). Our study demonstrates that pediatric flat foot has the capacity to significantly influence the values of the angle of the calcaneus and tibia in a frontal plane.

This paper represents an experimental study that tried to highlight the effectiveness of a professional training activity that is structured and directed toward concrete aspects, represented by the correctness and quickness of information transmission, by a quick organization of the group, establishing the working time, the cool-down break, and assessing the students' (colleagues') behavior. In order for us to know the leading ability, we did an initial and a final testing, both being observational. In order to train the leading and organizational skills throughout the experiment (which took place over the course of 14 weeks, 2 hours per week of direct meetings, and 2 hours of individual training), each student in the experimental group taught 5 lessons, of 40 minutes each, and participated in another 8 lessons as an evaluator of their colleagues' activity (who, in turn, taught their lessons). In the control group, each student taught only two lessons: an initial one (at the beginning of the semester), and a final one (at the end of the semester), while during the rest of the seminars they debated all the theoretical aspects of conceiving, leading (teaching), and conducting a lesson. The students in the experimental group recorded better results than the ones in the control group. The average values progress of the experimental group in the final stage was higher than the control group's by: 0.67 points for the correctness and quickness of the transmission of information, 0.79 points for establishing the working time, 0.83 points for assessing the cool-down break, and 0.35 points for assessing the students' (colleagues') behavior. The conclusions have emphasized the fact that the students' involvement in teaching and leading the seminar lessons, in a structured way, and directed toward certain aspects, can contribute to the training of the leading abilities for the practical lessons, and to a higher involvement of the students in the professional training process. This method of approaching the instructive-educational act, based on the students' involvement in teaching a large number of lessons, and including them in the assessment of their colleagues, represents a way that increase the value of the formative act.

The athletic result, represented by the score recorded during a competition, is determined by the quickness of the performances, by the power expressed in all segments. The actions of all the six players in the court depend mainly on their experience and value, and secondly, on the opponents' actions. The multitude, the diversity, and the precision of the individual and collective actions, but especially the quickness of the performances, depend on the complexity of the thinking process and creativity of the team's players, on the developed power that can be analyzed through the values of the assessment indicators.The "15 jumps" drill consisted in "a succession of jumps in place, linked between them, in which the elastic component is very important" (Nicu Alexe, 1993), during which "the muscle is similar to a two-cycle engine... and the energy is divided to the whole motor cycle that comprises the contractile and relaxation stage" (Vasilescu and Margineanu, 1979, page 80), and it represented an assessment possibility that allowed us to perceive certain information, important for designing the training process."The take-off height body weight ratio" (Epuran, 2005, page 362) presents us with information regarding the power that can be developed in the lower limbs. This developed power greatly determines the athletic outcome. It can be assessed, in the lower limbs, through the vertical take-off drill, and it is given by the athletes' ability to synchronize the contact of their soles to the floor, and the action of pushing the floor away. The vertical take-off is influenced by the value of the flexion angle. When this is under 90°, it "increases the quantity of elastic energy" consumed for performing of the take-off (Cordun 2009, page 171). "The vertical jump height, respectively the top point of the general weight center of the body depends on the height of the body mass center of the body during the take-off and on the flight height, the vertical movement, on the duration of the air ascension", but also on the developed power, on the ground contact time, and, not in the least, on the reaction force of the support, whereas the latter "depends on the forces applied on the core by the head and arms, and on the forces of the hip, knees and ankles" (Rata, 2001, page 75). These aspects, gathered from the specialized literature draw attention towards the way in which the control drill can be performed. The take-off power is measured with equipment testing the strength-speed qualities in the lower limbs, emphasizing the energy and control parameters; this equipment was in this case a DELSYS Myomonitor IV 16 channels electromyograph. With this drill we can get information regarding the basic elements of the neuro-motor, energetic, and control skills at the level of triple extension, during a maximal force-speed effort. The test is performed barefooted, and it is comprised of three series of 15 jumps in place each, performed using both legs, only the right leg, and only the left leg, and recorded using the electromyograph. Out of the 16 channels, we used 14 for the electrodes that would collect the values of the electrical activity in the muscles, and 2 channels for the pressure sensors to emphasize the contact with the floor. The data gathered through the 16 channels was recorded simultaneously. The EMG electrodes were positioned 7 for each leg, on the main muscle groups of the thigh and calf (quadriceps femoris, vastus medialis and lateralis, biceps femoris, tibialis anterior, gastrocnemius, being interested especially in the relation between the biceps femoris and the quadriceps femoris), and the pressure sensors were put each on one leg, on the tip of the big toe. …

To the research six girls, 16-17 years old, participated. In the two competitions, the running time on the elk and the number of steps were recorded for each trial. The analysis of the data revealed differences in terms of the time to complete the moose, but also a constancy in the 6 jumpers. Differences were found between the number of steps taken by the elk and the maximum performance achieved by each jumper, a good Pearson correlation value calculated for the number of steps and the mean time recorded for running the elk (with values of .998 and .986), which confirms the research hypothesis. .

Two of the most common residual symptoms of an ankle sprain are: the occurrence of chronic joint instability and agonist-antagonist muscle imbalances, expressed numerically by the values of the muscle coactivation index. The purpose of the research was to demonstrate that the use of proprioceptive exercises leads to the improvement of the degree of chronic joint instability and of the values of the muscle coactivation index. The research had a number of 22 subjects, handball players, whose age was between 15 and 16 years. The degree of joint instability was established by using the "Foot and Ankle Disability Index" Questionnaire, while the values of the muscle coactivation index were calculated following the electromyographic measurements. The obtained results highlight the efficiency of the proposed proprioceptive exercise programme, the statistical significance of the obtained results (by improving the initial and final values), as well as the existence of correlations between all evaluated parameters (muscle coactivation index, number of ankle sprains and degree of joint instability). The conclusions of the research underline the efficiency of proprioceptive exercises in diminishing the degree of chronic joint instability and in improving the values of the muscle coactivation index. Based on the results obtained, the research acquires an important practical value, because the proposed intervention programme has applicability in all sports sectors.

In order to train the assessment capacity, we have performed the following: an initial testing for observation purposes and a final one for realization demonstration purposes. The findings have revealed that students' involvement in the assessment practical process in a structured and directed manner may contribute to the training of the assessment ability and to their better involvement in the training process. The approach to the instructional-educational process, based on the students' involvement in the process for assessing their fellow students is a manner to increase the value of the training process.

The study aims to surprise the skills development in middle-school pupils. The specific nature of this study is that, besides their formal education, which all the subjects attended (52 male and female pupils), the experimental group subjects were comprised also in a non-formal education system, performing athletic activities (dance, handball, and judo) outside their classes, a two hours session per week. The study tried to confirm the hypothesis stating that the pupils performing practical activities in children's clubs can develop their effort capacity more than the others. As research methods, we used the study of the professional literature, the tests method, the inquiry method, and the statistical-mathematical method. The subjects' results from the initial and final tests were centralized and analysed. The values of the analysed indices (average value, standard deviation, maximum and minimum value) during the challenges and in the questionnaire have shown the different effort capacity level in the subjects of the two groups. In conclusion, our research has emphasized the fact that the pupils performing practical activities within a non-formal education can develop their effort capacity more than the others. Thus, the hypothesis was confirmed. The females in the experimental group have recorded higher average values than the control group with 1.32s for the 50m sprint, with 10.27 cm for the long jump, with 3.59 repetitions for the arm strength challenge-push-ups, with 9 seconds for the 600 m endurance run, and with 0.60 points for the coordination challenge. The males in the experimental group have recorded higher average values than the control group with 0.79 s for the 50m sprint, with 7.07 cm for the long jump, with 3.50 repetitions for the arm strength challenge-push-ups, with 36 seconds for the 800 m endurance run, and with 1.00 point for the coordination challenge. The average values have increased in the experimental group more than in the control group, during all the final challenges, which shows a better effort capacity in the subjects.

The present study aims to analyze the level of aggressivity of two study groups made up of subjects aged between 15 and 18 years: one group includes performance athletes from Martial Arts Club Budo Seishin and the other one non-practitioners from Alexandru Vlahuță Highschool. Martial arts and ju-jitsu in particular can influence the level of aggressivity of the subjects in a positive manner, helping relieve stress and frustrations. Having knowledge about these elements can provide information about the level of aggressivity of the subjects and we will verify whether ju-jitsu represents a solution to help interested people in constructively directing aggressivity. Our findings indicate an increased level of physical, verbal aggressivity and hostility in non-practitioners rather than in sportsmen, which validates the research hypothesis.

The hypothesis of the study is the following: it is assumed that there are differences between the efficiency of the game actions in the volleyball performance depending on the competitions’ location. The research methods used in the study: bibliographic method, data recording and processing method, statistical method and graphical method. The subjects of the study are the 14 athletes from the “Stiinta Bacau” women’s volleyball team in the 2016-2017 season. The results of the study revealed that there are statistically significant differences between the game action efficiency according to the competition’s location. The conclusion of the study highlighted that, depending on the venue of the competition, there are differences between the game action efficiency in the performance volleyball.

The research was conducted throughout the academic year of 2010-2011, in 9 middle-schools and 8 high-schools from Bacau County, Romania. In order to obtain complete information on the researched theme, we used one of the fundamental techniques of inquiry, the questionnaire, which comprised closed questions and predetermined answers. After finishing the research, we can say that music should be present in every physical education lesson, especially in the ones teaching gymnastics.

Cerghit (2006, p.343) highlights that the fundamental acquisitions in the pedagogical process lead to "easiness of thinking, dexterity and practical skills; attitude and interest" and that the "behavior patterns are achieved through practice and exercise"; therefore we initiated a study on the creative attitudes of students in order to perform a formative education activity. Subscribing to the idea that "the approach of the compulsory contents and the appropriate assessment system… can lead to increased interest and motivation for the practice of physical exercises" (G. Ra and Gh. Ra, 2008 p. 142), and that physical education is a creative activity, we start from the hypothesis that students in physical education have a score above half of the reference value in all sixteen creative attitudes. Method: The study involved twenty subjects (male and female students) and the method consists of administration of the questionnaire of creative att...

The degree of joint instability was established by using the "Foot and Ankle Disability Index" Questionnaire, while the values of the muscle coactivation index were calculated following the electromyographic measurements. The obtained results highlight the efficiency of the proposed proprioceptive exercise programme, the statistical significance of the obtained results (by improving the initial and final values), as well as the existence of correlations between all evaluated parameters (muscle coactivation index, number of ankle sprains and degree of joint instability). The conclusions of the research underline the efficiency of proprioceptive exercises in diminishing the degree of chronic joint instability and in improving the values of the muscle coactivation index. Based on the results obtained, the research acquires an important practical value, because the proposed intervention programme has applicability in all sports sectors.

The study aims to surprise the skills development in middle-school pupils. The specific nature of this study is that, besides their formal education, which all the subjects attended (52 male and female pupils), the experimental group subjects were comprised also in a non-formal education system, performing athletic activities (dance, handball, and judo) outside their classes, a two hours session per week. The study tried to confirm the hypothesis stating that the pupils performing practical activities in children's clubs can develop their effort capacity more than the others. As research methods, we used the study of the professional literature, the tests method, the inquiry method, and the statistical-mathematical method. The subjects' results from the initial and final tests were centralized and analysed. The values of the analysed indices (average value, standard deviation, maximum and minimum value) during the challenges and in the questionnaire have shown the different effort capacity level in the subjects of the two groups. In conclusion, our research has emphasized the fact that the pupils performing practical activities within a non-formal education can develop their effort capacity more than the others. Thus, the hypothesis was confirmed. The females in the experimental group have recorded higher average values than the control group with 1.32s for the 50m sprint, with 10.27 cm for the long jump, with 3.59 repetitions for the arm strength challenge-push-ups, with 9 seconds for the 600 m endurance run, and with 0.60 points for the coordination challenge. The males in the experimental group have recorded higher average values than the control group with 0.79 s for the 50m sprint, with 7.07 cm for the long jump, with 3.50 repetitions for the arm strength challenge-push-ups, with 36 seconds for the 800 m endurance run, and with 1.00 point for the coordination challenge. The average values have increased in the experimental group more than in the control group, during all the final challenges, which shows a better effort capacity in the subjects.

The present study aims to analyze the level of aggressivity of two study groups made up of subjects aged between 15 and 18 years: one group includes performance athletes from Martial Arts Club Budo Seishin and the other one non-practitioners from Alexandru Vlahuță Highschool. Martial arts and ju-jitsu in particular can influence the level of aggressivity of the subjects in a positive manner, helping relieve stress and frustrations. Having knowledge about these elements can provide information about the level of aggressivity of the subjects and we will verify whether ju-jitsu represents a solution to help interested people in constructively directing aggressivity. Our findings indicate an increased level of physical, verbal aggressivity and hostility in non-practitioners rather than in sportsmen, which validates the research hypothesis.

Material and methods: As research methods we used: the observation, the study of the specialized literature, the test, the statistical-mathematical method, and the chart method. Our assessment regarding how much the chosen profession matches the students' predispositions was made through the self-knowledge test "What profession suits you", promoted by Nicolae Radu, in 2007, pag. 147-149. The test emphasizes the dominance or non-dominance of manifestation of the inventive, directive, and organizing type of behavior in the students. This research was conducted on 30 students. Results: In Table 1 we present the recorded results for the 30 subjects. We observed that 70% had an individual score higher than the average value for the inventive behavior, and 96.67% had it h...

The research was conducted throughout the academic year of 2010-2011, in 9 middle-schools and 8 high-schools from Bacau County, Romania. In order to obtain complete information on the researched theme, we used one of the fundamental techniques of inquiry, the questionnaire, which comprised closed questions and predetermined answers. After finishing the research, we can say that music should be present in every physical education lesson, especially in the ones teaching gymnastics.

Cerghit (2006, p.343) highlights that the fundamental acquisitions in the pedagogical process lead to "easiness of thinking, dexterity and practical skills; attitude and interest" and that the "behavior patterns are achieved through practice and exercise"; therefore we initiated a study on the creative attitudes of students in order to perform a formative education activity. Subscribing to the idea that "the approach of the compulsory contents and the appropriate assessment system… can lead to increased interest and motivation for the practice of physical exercises" (G. Ra and Gh. Ra, 2008 p. 142), and that physical education is a creative activity, we start from the hypothesis that students in physical education have a score above half of the reference value in all sixteen creative attitudes. Method: The study involved twenty subjects (male and female students) and the method consists of administration of the questionnaire of creative att...
