Archery may be classified with the sport disciplines driven by targeted skillful actions. Movement accuracy is secured by a harmonized sequence of actions with the shooting process phasing and timing being a key for success. Objective of the study was too profile the shooting process timing by biomechanic, electromyographic (EMG), electroencephalographic (EEG) and autonomic functionality indices. Four Russian Masters of Sports were sampled for the standard shooting sequence profiling test to obtain the following test data: kinematic parameters of the radiocarpal joints fixed with discretion frequencies of 50HZ and 120Hz; EMG of 8 core muscles; EEG in 19 points; electro-oculograms; pneumograms; ECG with application of motor activity sensors; and with WinEEG software applied to process and analyze the EEG test data. The movement profiling by the biological markers made it possible to identify the key functional periods and phases in the setup, preparation and execution of a shot. Setup period I was classified into two phases to reach an optimal prime vertical posture. Dynamic vertical-posture period II includes three phases. And aiming period III includes two phases followed by a shot. The biological markers to profile the radiocarpal joints fluctuations versus the EEG data made it possible to analyze the functionality rates in periods I and III and find their variations versus the shooting accuracy rate.

Keywords: archery, shooting process timing and phasing, biological markers of periods.
