The effect of ball pattern and different type of curved trajectories during free kicks in goalkeepers interceptive behaviour

Free kicks in football often provide a good scoring opportunity. However, the exact goalkeeping interceptive behaviour for any type of spin-induced vertical curve has never been studied before. We will do so here in two steps. First, we will directly compare the behavioural effects of equivalent amounts of spin along vertical and horizontal axes, generating horizontal and vertical curves respectively (Experiment 1). Second, we will examine goalkeeping behaviour in situations where, due to spin, the ball curves just into the goal at the last moment (Experiment 2). Another aspect that may influence the interceptive performance of a goalkeeper is the print pattern one the ball surface, particularly in the context of curving free kicks. Here, using the free kick paradigm, we will examine the effect of the ball’s pattern for trajectories with either vertical and horizontal spin-induced curve (Experiment 3)

Short rehabilitation training program may improve postural control in children with autism spectrum disorders: preliminary evidences

International audienceAutism Spectrum Disorders subjects (ASD) is characterized by postural control deficits. This study aimed to explore the effect of a short postural rehabilitation training program on postural capabilities in children with ASD. Two groups (G1 and G2) of twenty children with ASD of IQ-, sex- and age- matched (mean age 11.7 ± 2.4 years) were included in this study. Posture was recorded by using the Balance Quest from Framiral on unstable platform in three different viewing conditions. The rehabilitation program consisted in two distinct postural control training exercises. Postural recordings were performed twice at T1 and T2 for both groups of children. Between T1 and T2 a 6-minute postural training was performed by the G1 group only, while the G2 group had a 6-minute of rest. Children were allocated randomly to the G1 or G2 groups. At T1, postural instability was similar for both groups of ASD children (G1 and G2) desp+\ite viewing conditions. At T2, we observed an improvement of postural control related to a mixed effect of training rehabilitation but also of test-retest. Knowing the potential of new rehabilitation strategies, the impact of postural control deficit in ASD children needs to be reconsidered. Well design case-control studies are requested to ensure scientific validity of postural rehabilitation training program
