The aim of the study was to determine reliability and factorial validity of six basketball shooting accuracy tests. Fifty five healthy basketball players (age 19.1 ± 3.1 years; body mass 83.4 ± 12.5 kg; height 189.1 ± 8.2 cm; body fat percentage 13.1 ± 4.1) from four Bosnian basketball teams participated in this research. The applied tests have been constructed in order to measure basketball sh...

The use of lead bullets and shot at shooting ranges is under increasing scrutiny as a potentially significant source of Pb pollution. This study assessed Pb contamination in the soils of two shooting ranges (TRR and MPR) in Florida. Soil samples were collected from the two ranges and analyzed for total Pb to determine Pb contamination. Selected spent bullets and berm soil samples were mineralog...

Boundary value problems arise in many applications, and shooting methods are one approach to approximate the solution of such problems. A Shooting method transforms a boundary value problem into a sequence of initial value problems, and takes the advantage of the speed and adaptivity of initial value problem solvers. The implementation of continuous Runge-Kutta methods with defect control for i...

We consider the problem of ray shooting amidst spheres in 3-space: given n arbitrary (possibly intersecting) spheres in 3-space and any " > 0, we show how to preprocess the spheres in time O(n 3+"), into a data structure of size O(n 3+"), so that any ray-shooting query can be answered in time O(n "). Our result improves previous techniques (see 3, 5]), where roughly O(n 4) storage was required ...

We examined the effects of visual control training on expert wheelchair basketball shooting, a skill more difficult than in regular basketball, as players shoot from a seated position to the same rim height. The training consisted of shooting with a visual constraint that forced participants to use target information as late as possible. Participants drove under a large screen that initially bl...

Shooting training is associated with exposure to a considerable amount of unique noise. We wanted to evaluate noise exposure during such training. Our observations especially apply to professional sport shooters, but they are also valid for shooting coaches/instructors. We collected acoustic signals in 10-, 25- and 50-m as well as open-air shooting ranges. The recorded material was analysed wit...

This paper investigates spatial and visual analytics as means to enhance basketball expertise. We introduce CourtVision, a new ensemble of analytical techniques designed to quantify, visualize, and communicate spatial aspects of NBA performance with unprecedented precision and clarity. We propose a new way to quantify the shooting range of NBA players and present original methods that measure, ...
