In the basketball game, lower extremity strength plays a key role in various game actions. The jumping mat (Chronojump), an open-source (free software and open hardware), is available to the public on official servers, emphasizing peer review and corrections by the user community. The aim of this study was to establish the explosive power of the lower limbs of 16-year-old female basketball players from the Bulgarian National Basketball Team. We used specialized software, a signal transducer, and an electro-contact mat Chronojump. The subject of the study was the explosive power of the lower limbs of 16-year-old female basketball players from the national team of Bulgaria. The object of the study was the performance of the Chronojump platform tests to establish the explosive strength of the lower limbs. The study was conducted among 16 active female basketball players selected for the Bulgarian national team. Each participant performed all jumps at the same time of day. They performed CMJ - 90-degree squat jump; SJ - Squat, two-second hold, and jump; CMJAT - Jump with arms extended forward and up; RCMJ - Manipulative 90-degree squat jump; Stiff ness - Manipulative ankle jump. The test's mathematical-statistical results were processed with variance analysis and One-way ANOVA, with a critical value of the F-criterion (F = 2.38) and high statistical reliability (Pt ≥ 95%). Results showed that hand involvement is key in rebounding. In terms of jumping endurance and explosiveness quotient, female athletes had a lower level of development. This research has the potential to significantly impact the training and performance of female basketball players. [ABSTRACT FROM AUTHOR]

The regularities in the dynamics of the physical development of the female organism and the changes that occur in it led to problems in the manifestation of motor qualities at different ages. The study aims to optimize the training process of U12, U14, and U16 basketball players by revealing the factor structure and identifying the main factors of physical development and sports fitness in different age groups. Specialized literature was analyzed to carry out the research, and a test battery for sports-pedagogical testing was used, according to Borukova (2021). 173 female basketball players were studied. The results showed a change in the factor models of physical development and the specific performance with age increasing. The factor components with the most significant weight for the U12 are the anthropometric characteristics, for the U14 are the technical basketball skills, while for the U16, the height is a prerequisite for more outstanding achievements in the maximum vertical jump. The rearrangement of the features in the integral factor structure of the sports preparedness enables the coaches to optimize the training process for the U12, U14, and U16 female basketball players.

The view of experts regarding women basketball in Europe is that in recent years the effectiveness of shooting baskets is slowly diminishing, which impacts the game negatively. The purpose of our research is to effect studies related to the effectiveness of shooting the basket in women basketball for various age groups: U16, U18, and U20. For the research, we have studied specialized literature and analysed game effectiveness statistic data from the Genius Sport official system for registering the game indicators of the European Basketball Federation (FIBA). The initial data are processed mathematically-statistically by variation analysis, relative share for establishing the effectiveness of shooting baskets from various distances, and comparative analysis. We have researched shooting effectiveness data from the last European championships for the three age groups. The results show a decrease in the competitors' skills for effecting baskets by the growth of age. We can conclude that women's basketball is a dynamic sport with many elements, but the effectiveness of shooting baskets is at its core, which is something that is often forgotten. Coaches working at each level should use at least 30% of the training and training process for specific shooting exercises for the basket; this is the minimum that can stop this process so that the game of basketball does not go into an existential crisis.

The purpose of the present study is to disclose the factor structure of the physical development and the specific workability of growing up girl basketball players. The present study was held during March - September 2015. The object of the study are the basic signs of the physical and technical-tactical preparedness in basketball of 14 years old girl basketball players. The contingent of the study are 66 girl basketball players born in 2001-2003 from the first five clubs having taken the first places in the State championship during the 2014/2015 season. Most important for the 14 years old girl basketball players is the so-called morphological factor, which discloses the high importance of: the length of the body: the height and weight indicators.

The purpose of the present study is to make analysis and assessment of the physical development and the specific workability of "September 97" girls team from Sofia. The present study has been made during March-June 2015. Subject of the study is the physical development and the specific workability of 14 years old girl basketball players. Contingent of the study is 10 girl basketball players born in 2001-2003 from "Septemvri 97" basketball club-Sofia taking part in the State championship of the Bulgarian basketball federation. For the needs of the study a testing has been made of all competitors from the team according to 25 indicators bearing information about the basic signs for the physical development and the specific basketball workability. The results fivm the study have been subjected to mathematical-statistical processing by analysis of variance and sigma method of assessment. The totality we have studied is homogeneous in relation to the height, stretch, special speed for moving along the playground with and without a ball, the speed of the motive reaction, the explosive strength of the lower limbs under coordination, complicated movements in the space and the speed endurance. Great individual differences are observed in relation of the basketball players to work with the ball at site and at high speed. [ABSTRACT FROM AUTHOR]

The object of the study is some basic signs of the specific physical and specific technique-tactic preparedness and their development under the effect of specific motive activity (by means of basketball). Sample of the study consists of 12 girl pupils (6th - 7th grade) from the sports school in Varna, competing at "Odessos " sport club and 12 girl pupils from the "Saint Naum " sports school in Sofia, born in 1998-1999. For the needs of the study a battery test is applied covering 10 indicators. The following methods of research have been applied for implementing the objective and tasks set up in the study: review study of specific literature; expert evaluation; sports-pedagogical tests. The results from the comparative analysis of the preparedness of the 14 years old pupils from the sports schools in Varna and Sofia provide the reason for making the following conclusions: The pupils from Varna considerably outdo their peers from Sofia in relation to the development of the specific swiftness of moving along the terrain without a ball, the speed endurance and the quickness of shooting a basket; The pupils from Sofia do not considerable outdo their coevals from Varna in relation to the explosive strength of the lower limbs at vertical efforts, dynamics of the abdominal muscles and the execution of free throws. These differences might be explained by random reasons. [ABSTRACT FROM AUTHOR]
