The purpose of this study was to investigate the effect of an eight-weeks general preparation exercise on some selected biomechanical, anthropometrical and physiological parameters of the Iranian national Females' Taekwondo team. The biomechanical, anthropometrical and physiological parameters included; body weight, cardiovascular endurance, muscular endurance, speed, agility, visual reaction time, anaerobic power and body composition. The results of body weight, agility, visual reaction time and anaerobic power (ergo jump test) test were slightly lower in after training. In this regard, the main emphasize of general preparation phase is enhance the cardiovascular endurance and muscular strength, significant reduction in bf% and significant increase in aerobic and anaerobic factors following exercise was similar to the other investigations (Mirzaie et al."

METHOD

Nine elite member of Iranian national females' Taekwondo‌ team‌ (age‌ 23.22±1.98 years old, and weight 61.88±8.44‌ kg) participated in this study. All participants read and signed an approved informed consent form. The exercise program‌ consist‌ of‌ 72 sessions (3 session reviewing and practicing techniques, 2 sessions of combat (live‌) taekwondo‌, 2 sessions strength training, 1 session interval running and 1 session of endurance training each week) .The testing was‌ conducted‌ twice‌, before and after the 8-weeks training period. The biomechanical, anthropometrical and physiological‌ parameters‌ included‌; body weight, cardiovascular endurance, muscular endurance, speed, agility, visual reaction time, anaerobic power and‌ body‌ composition‌. body composition analyzer (in body 220) was used to assess the body fat percentage‌, reaction‌ time was measured with visual reaction time apparatus(Satrap company, Iran), Bruce protocol‌ was‌ used‌ to estimate vo2 max, a 40-yard sprint test was used to assess the speed‌, 4×9 m shuttle‌ run test was required to assess agility, 1-min bilateral jump was used to‌ assess‌ the‌ lower extremities endurance and 15 second ergo- jump and Sargent test was required to assess‌ the‌ anaerobic power of the subjects. And inferential statistics Kolmogorov- Smirnov test was‌ used‌ to‌ check the normality distribution, using a paired t- test to compare variables before and after training, with‌ a significant‌ level‌ of (p≤0.05).

RESULTS

The results of functional test are presented in table‌ 1. The‌ bf% of the subjects significantly decreased.The results of body weight, agility, visual reaction time and‌ anaerobic‌ power (ergo jump test) test were slightly lower in after training. The‌ results‌ of anaerobic power, aerobic test and muscle‌ endurance‌ significantly‌ increased.
