PURPOSE The aims of the present study were: (1) to compare the differences in the ball release speed and throwing accuracy between the ABOVE and SIDE throw; (2) to analyze kinematic differences of these two throwing techniques; and (3) to give practical applications to team handball coaches and players. METHODS Ball release speed, throwing accuracy, and kinematics were measured via the Vicon ...

Our perceptual experience is largely based on prediction, and as such can be influenced by knowledge of forthcoming events. This susceptibility is commonly exploited by magicians. In the Vanishing Ball Illusion, for example, a magician tosses a ball in the air a few times and then pretends to throw the ball again, whilst secretly concealing it in his hand. Most people claim to see the ball movi...

Design, control, and performance of a ball-throwing robot are examined in this paper. The objective of this project is to provide an interactive ball-throwing robotic arm for illustrating the roles of engineers and computer scientists in the design and usage of such a system to high school or pre-engineering students. Activities in particle dynamics and trajectory calculation will provide basic...

In the vanishing ball illusion (VBI), a magician throws a ball up in the air twice, after which he pretends to toss it up again, when in fact it remains secretly concealed in his hand. Observers perceive an imaginary ball disappearing into the air. According to Kuhn and Land (2006), the VBI during the fake throw is mediated by the magician's gaze and/or head direction (also called "social cues"...

This study investigated the relationship between physical qualities and contact technique proficiency in rugby union players. Thirty-eight (n = 38) male academy players participated study. Physical measures of anthropometry, functional mobility, strength endurance, strength, power, speed, agility, anaerobic aerobic endurance were assessed. Tackler, ball-carrier, ruck assessed using video analys...

This study aimed to discover the effect of learning method and motivation on improvement throwing catching ball for elementary school students. The samples were 60 students acquired using treatment by level 2x2 design with tukey test a =0.05 level. results show 1) groups A1 A2 obtained Fh Ft, i.e., 17.9 4.15; therefore, there is an between group individual throw-catch skills, Qh = 8.54 dan Qt 3...

This paper describes a computational model which simulates the change in the use of optional infinitives that is evident in children learning Dutch as their first language. The model, developed within the framework of MOSAIC, takes naturalistic, child directed speech as its input, and analyses the distributional regularities present in the input. It slowly learns to generate longer utterances a...

Quiet eye training (QET) may be a more effective method for teaching children to catch than traditional training (TT) methods, but it is unclear if the benefits accrued persist in the long term. Thirty children were randomly allocated into a QET or TT group and, while wearing a mobile eye tracker, underwent baseline testing, training and two retention tests over a period of eight weeks, using a...
