The Relationship between Range of the ankle motion, Q angle and back stroke kicking on male Swimmers

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.
