Studying of the relationship between some biokinetics variables of the arm from inside water with some anthropometric measurement in the 25 m butterfly swimming

The research aimed at : 1. Recognizing the values of some biokinetics variables of the arm from inside water in the 25 m butterfly swimming . 2. Recognizing the values of some anthropometric measurement . 3. Finding the relationship between the values of some biokinetics variables of the arm from inside water with arm length in the 25 m butterfly swimming . The descriptive method was used . the sample included ( 5 ) swimmers of the senior group of Nineveh team . the technical scientific observation , analysis and measurements were used as means to collect the data to obtain some of the biokinematics variables values and some anthropometric measurements values , to achieve the technical scientific observation accurately , the videography was used . the study included a number of biokinematics variables of the arm and anthropoetric measurements . the data have been processed statistically by using the mean , standard deviation and simple correlation . the researchers concluded the following : There Were no significant correlations between some biokinetics variables values of the arm from inside water with arm length . The researchers recommended some recommendations to be utilized in the learning and coaching to get the best performance . * Keywords: Bio kinetics- anthropometric measurement- swimming-25 m butterfly
