The norm of bioenergetics characteristics of elite and advanced male and female Iranian Badminton players

The purpose of this study was to collect the norm of bio-energetic characteristics of male and female elite and advanced Badminton players in Iran based on gender differences. This is a descriptive research of the kind of normative survey. Statistical population of the research includes all elite and advanced male and female Badminton players in Iran during 2010 including 128 elite and advanced players, 64 male (mean age 19.92 + 3.4 yr. height 176.53 + 6.13 cm, weight 70.46 + 6.77 kg and competitive experience 9.27 + 2.68 yr) and 64 females (mean age 17.00 + 2.4 yr, height 163.90 + 5.87 cm, weight 56.18 + 5.75 kg and competitive experience 6.27 + 1.55 yr). The statistical sample was equal to the statistical population. Regarding the specific characteristics and demands of Badminton, aerobic power, alactic anaerobic power and lactic anaerobic power were measured. Also based on the distribution of the obtained scores, frequency tables and percentage points of the players were drawn based on gender differences in order to collect the related norms, using spss-15 software. Then according to the percentage norm and Likert scale, player's performance was classified. One sample t test was applied to compare bio-energetic characteristics of national and world elite Badminton players. The results of this study indicated that the average aerobic power of Iranian male and female elite and advanced badminton players, respectively 55/16 and 44/05 ml/kg.min are significantly lower than the values for world male and female elite badminton players which are 63 and 50 ml/kg.min (p 0.01). also, the average of sergeant vertical height of Iranian male and female elite and advanced badminton players accounting for 63 and 48 centimeters are again significantly lower than the reported values for world male and female elite badminton players as 75 and 56 centimeters (p 0.01) but lactic anaerobic power of male and female Iranian elite and advanced badminton players was in a good situation. The results of study highlight an urge to review and pay more attention to designing professional practices in order to improve and develop the aforementioned factors.
