Flexibility tests are sometimes thought to be related to range of motion in dynamic activities, but such a relationship remains to be determined.
To determine the correlation between flexibility and hip and knee angles in Australian football kicking.
Correlation.
Biomechanics laboratory.
16 Australian Rules football players.
Hip and knee angles of the preferred kicking leg in a relaxed position were determined with a modified Thomas test. Maximum hip extension, the knee-flexion angle in this position, the maximum knee-flexion angle, and the hip angle at this position during the swing phase of maximum-effort drop-punt kicks were determined.
Significant correlations were found between hip flexibility and maximum hip extension (r = .65, P < .01) and hip angle at the maximum knee-flexion angle (r = .70, P < .01).
The data indicate a moderate association between hip flexibility and hip angles during kicking.
