Statistical analysis
Statistical analyses were undertaken using SPSS
(v12.0.1). All data were checked for normality using the
Kolmogorov-Smirnov and Shapiro-Wilk tests, where
normality was assumed if p > 0.05). A non-parametric
Friedman with a Post Hoc test (Mann-Whitney U) was
used to compare differences in accuracy between the
approach angles. Parametric differences in kick kinematics
between the approach conditions were analysed using
a repeated measures MANOVA (with approach angle as
the independent variable and kick kinematics as the dependent
variables). Shot accuracy and ball velocity
variables demonstrated a statistical power of 0.8. An
