The purpose of this research is to survey the relationship between range of the
ankle motion and Q angle and back stroke kicking on male swimmers. 34 on
available boy students swimmers were selected with mean and SD of age
23.68±2.28 years, weight 71.88±9.35 kg and height 176.11±5.52 cm in this
study. First, Right and Left Leg Q angles (to supine position), Range of Dorsal
flexion and plantar flexion motion were measured by the use of goniometry. And
their mean were calculated Right and Left Leg Q angles. Then test was
recorded of back stroke and kicking in distance 15 meter of pool. The number of
back stroke kicking done by the use of three referees and cinematography
technique. Later, the distance for per back stroke kicking was calculated by the
use of mathematical formula. The results of Pearson correlation coefficient
showed the significant positive correlation between Q angle with record of back
stroke kicking (r = -0/67, p ≤ 0/05). The results showed that swimmers may not
use all their range of the ankle motion, but optimized range of the ankle motion
to be their consideration. Also, Q angle measure (Q ≤ 16/23) could be important
in success, Talent Identification and selection of mentioned swimmers
