Abstract

The study aimed to identify the effect of variation of diversification by methods of elongation of the muscles of the arms in some physiological indicators represented by the electric muscles of some arm muscles and the time of completion of swimming (100) meters freestyle, and adopted the experimental approach by designing the same group of swimmers of the Iraqi youth team for the distance (100) meters free for the sports seasonal (2020-2021) of 12 swimmers, all of whom were deliberately selected from their community of origin (100%), in measuring achievement adopted an electronic stopwatch and to measure physiological variables adopted by (EMG) using two pickups of it For each right and left muscle of the arm muscles to read both the top and the electric signal area of each muscle in each distance (50) and (100) meters from the distance of this race, the experimentation in contrast was by codifying the training load of young swimmers by remaining difficult training between (90%-100%), and the variation in the independent variable by diversifying the two methods and their different application to be crowned by the training load from one unit to the other, and by determining the times of inter-comfort between repetitions and groups for muscle elongation exercises of the arms between Repeats (15-45) seconds, And between groups of (90-120) seconds, and between exercises of (5-10) minutes and this contrast allows the recovery of energy sources between one exercise and another after pressure to break the rule of (2-5) minutes, and after the completion of the experiment the researcher checked the results with a system (SPSS) to be extracts and applications that because of the variation of diversification by methods of muscle elongation of the muscles of the swimmers muscles (100) free effects in the physiology of electrical signals for neuromuscular control, to reflect positively on reducing the time of completion of their swimming to this distance, it is necessary to support Knowledge of swimming instructors (100) freestyle about the importance of varying diversification by methods of stretching the muscles of the arms, to depart from the limitations imposed by the exercises within the first energy system.

Keywords:

Muscle elongation, physiological indicators, swimming achievement (100) freestyle meters.
