Abstract(s)
In youth basketball, the ball’s size is adapted to fit the participants’ physical capacities and
improve the development of manipulative skills. The current study compared the kinematic param eters of the basketball shot (BS) performed with two different ball sizes. Twenty-seven adolescent
females aged 12.1 ± 0.9 years (height: 153.3 ± 8.0 cm; body mass: 48.8 ± 12.8 kg) completed 10 BS
trials from a frontal position at 5.75 m from the basket with two ball sizes: a smaller and lighter ball
(size five, 480 g) and the standard ball size for their age (size six, 566 g). No statistically significant
differences were observed for ball release variables or efficacy levels. Significantly greater shoulder
flexion was detected at release while shooting with a size six ball (F = 2.982, p ≤ 0.01). The shoulder’s
angular velocity at release was significantly lower while performing with a size six ball (F = 3.089,
p ≤ 0.01). No significant differences were found for the elbow or knee angles or angular velocities.
Stature and upper-body strength were significantly correlated with selected kinematic parameters.
A change in ball size may be a helpful strategy for coaches seeking to promote optimal shoot ing patterns, enhancing effectiveness and enjoyment, particularly among young people and more
inexperienced players.
