Proposal for a Didactic Aid to Practice the Bank Shots in Basketball

The aim of the paper was to propose a didactic aid to practice and develop bank shots in basketball. Four basketball players (three men and one 13-years old woman) were shooting bank shots from six distances (1, 2, 3, 4, 5 and 6 m) and at four angles (90°, 75 °, 45 ° and 25 °) respective to the board. An experimenter positioned behind the transparent backboard recorded the points of impact of 15 successful shots (without touching the rim) for each of the above distances, angles and shooters. With perpendicular shots at the backboard, we identified only negligible dislocation of the set of impact points. With angled shots, the set of impact points tended to move towards the side edge of the board and upwards depending on the angle of the shooter's position to the board and his/her distance. The farther the shooter from the basket and the lower the angle at which the shooter was shooting, the closer the impact point was towards the upper corner of the board.

We proposed a very simple and economically viable didactic aid to practice bank shots, consisting of a circle and two slanted ellipses placed on the backboard.

Physical characteristics play an important role in the selection of young basketball players and the progress in their playing performance. The aim of the study was to analyze differences in chosen physical characteristics of Slovak U17 female basketball players with respect to their playing positions. We assumed, that there will be statistically significant differences between playing positions in each performance tests results. Chosen characteristics were analyzed for 14 players (mean/SD, age 16.34±0.82; body height 179.72±8.04 cm; body weight 67.62±7.10 kg; body fat 16.59±2.04 %; VO2max 46.20±4.71−1.min−1) according to their playing positions (guard, forward, center). Five specific performance tests for each player were conducted as a 3/4 Basketball court sprint, 10 × 5m Shuttle test, Lane agility drill, No-step vertical jump and Maximum vertical jump. The differences in tests results by playing positions were evaluated by one-way ANOVA. There were no significant differences found in results of chosen performance tests between playing positions (p>.05). In spite of fact, that there were no significant differences, we found interesting results between playing positions in physical characteristics. Guards had better results in speed (3.73±0.16 s), quickness (17.43±0.56 s) and both lower-body power tests (47.16±3.06 cm; 57.00±3.40 cm) than forwards and centers. Forwards had the best results in agility test (12.54±0.43 s). The results of this study produce useful information about physical characteristics of young basketball players according to their playing position and help to diagnose and improve their performance.

In this study, the quality of the aquatic habitats of mountain and piedmont streams was evaluated using the ‘Instream Flow Incremental Methodology (IFIM)’ decision-making tool. The quality of habitats was interpreted from the behaviour of bioindicators in the form of habitat suitability curves (HSCs). From 1995 until the present, 59 different reaches of 43 mountain streams in Slovakia and 3 validation reaches were evaluated, and the results analysed. The aim of this study was to generalize the parameters of the HSCs for the brown trout. The generalized curves will be useful for water management planning. It is difficult and time-consuming to take hydrometrical and ichthyological measurements at different water levels. Therefore, we developed a methodology for modifying suitability curves based on an ichthyological survey during a low flow and a flow at which fish lose the ability to resist the flow velocity. The study provides the information how such curves can be modified for a wider flow range. In summary, this study shows that generalized HSCs provide representative data that can be used to support both the design of river restoration and the assessment of the impacts of the water use or of climate change on stream habitat quality.
