Abstract

The study aimed to:

         Manufacturing modern starting platform (with rear armrest) according to the specifications and global measurements. To identify the values of some Biokinmatics  variables and Biomechanics by  using  a device (Foot Scan) for two types of normal and track start with rear armrest) down to the water in the freestyle –butterfly and breaststroke swimmers advanced.

     The researchers use descriptive approach way of analytical style and comparison. Sample consisted of (5) elite swimmers from the province of Kurdistan . Use technical scientific observation and testing، measurement and analysis methods for data collection and values ​​of (Foot Scan) foot scanner.  He use one type of camera (Casio high speed Exilim) Chinese-made and speed were (240) image it put on after (6.M) in the left side of the swimmer and high (120c، m (from the ground of the swimming pool). Use the start test of both types (normal and with rear armrest) and Foot Scan has been placed on the both platform for the front and back leg  and start the regular presence of front and back  platform and the included power by Foot Scan and variables of Biomechanics by video imaging. The devices start  before the swimmer begin the start and the device of foot scan start with the swimmer begin the  start and after completion of the start to make sure that the devices attempt successfully recorded and all swimmers and the two types of the platform. Statistically using the arithmetic mean and standard deviation and t- test samples dependent. To process data using statistical bag (SPSS، 20).

The  conclusions : achieved statistical values ​​in the platform palm and the platform without  armrest to the variables of power using a foot scan to the front leg and back leg number of moral differences and non-moral between platforms were differences moral in variables (the sum of the total power and time to reach the maximum power and total maximum power of ten areas، pressure and space pressure total time total) for the benefit of the podium behind the palm of the front leg and were differences proportion of the total variables front man 83% values ​​for the benefit of the podium palm front of the leg، and the rest of variables appeared the differences in circles calculations، but did not live up to the point of moral which 17% were differences proportion of the total Background values ​​of variables leg 66% for the benefit of the podium palm background of the leg، and the rest of variables where the differences in the calculation circles appeared but did not live up to the point of a moral 34%.
