players.

Kicking accuracy is an important component of soccer performance. We
constructed a plywood target measuring 243.5cm wide x 122cm high.
Carbon paper applied to the surface of the target allowed
measurement by 2 raters from a bull's-eye to 10 ball marks left by
kicks. Intraclass correlation coefficients with 95% confidence
intervals were used to determine the intra- and interrater
reliability of the measurement to each ball mark. Mean and median
distances from bulls-eye to ball mark were 89.9cm and 97.9cm,
respectively (range, 25.7 to 150.75cm). The intraclass correlation
coefficients for intra- and interrater reliability were 0.99. The
root mean square error of measurement indicated that accuracy of
measurement was within 0.15cm. These results suggest that our method
of assessing kicking accuracy is a valid and reliable tool for
analysing performance. Because this tool closely replicates kicking
into a soccer goal, we feel that it also has validity. To our
knowledge, no other tool or measure (e.g.. number of shots on goal
or number of goals per game) has comparable validity and
reliability. This method can be used as a training tool and for
future investigations of kicking accuracy.
