A new paper by ARIHHP Assistant Professor Natsuki Sado and colleagues has been published in Human Movement Science.
A previous study showed that football instep kicks with the right leg resulted in a right-up-left-down error distribution and vice versa. However, this was the result of multiple kickers and it was not clear what individual differences existed in the error distribution.
The main findings are as follows:
1. that right-up-left-down error distributions were also observed in all 27 righty kickers in individual-level, too, but there are large inter-individual variabilities in the shape (assessed by the ellipticity of the 95% confidence ellipse) and direction (assessed by the direction of the 95% confidence ellipse major axis) of the error distribution.
2. even if the kicking precision is the same, the individual variability in the error shape and direction have a substantial effect on the probability of shots on goal when aiming at the same point.
The findings of the present study provide a new perspective to be taken into account for optimising motor planning in various goal-directed motor tasks, such as football shooting, where errors are defined in two dimensions, not only in accuracy or precision but also in ‘inter-individual variability in the error shape and direction’.
