The aim of present study was to evaluate the relation of anthropometric, physical fitness traits and lung capacities with success of Iranian elite Greco-Roman wrestlers. Twenty five Iranian elite Greco-Roman wrestlers (22 ± 4 years old) (both of light and heavy weights) participated in present study. Anthropometric characteristics, physical fitness traits and lung capacities were tested in the exercise physiology laboratory. Our results showed a significant and positive correlation between arm spam, as only anthropometric trait, and success of Iranian elite Greco-Roman wrestlers. Also, maximal oxygen consumption, dead lift, squat, bench press, agility, shoulder and-wrist elevation, sit and reach, reaction time-eye/left hand, reaction time-eye/foot, reaction time-ear/left hand, reaction time-ear/foot have positive correlation with their success. Furthermore, there were a significant and positive correlations between inspiratory reserve volume, tidal volume, forced vital capacity, forced expiratory volume (second), maximal voluntary ventilation and success. In contrast, we observed a negative and significant correlation between body fat (%) and success of Iranian elite Greco-Roman wrestlers. Physical fitness traits and lung capacities have greater potential than anthropometric characteristics in the prediction of Greco-Roman wrestler's success in championship levels.

Objectives: This study aimed to evaluate how lung capacity and anthropometric and physical fitness traits are associated with success of Iranian elite Greco-Roman wrestlers.Methods: Twenty-five male Iranian elite Greco-Roman wrestlers (22 ± 4 years old) (both of light and heavy weights) participated in the present study. Anthropometric characteristics, physical fitness traits, and lung capacity were tested in the exercise physiology laboratory. Results: Our results showed a significant and positive correlation between arm span, as the only anthropometric trait, and success of Iranian elite Greco-Roman wrestlers. Also, maximal oxygen consumption, dead lift, squat, bench press, agility, shoulder and wrist elevation, sit and reach, eye/left hand reaction time, eye/foot reaction time, ear/left hand reaction time, ear/foot reaction time were positively correlated with success. Furthermore, there were significant and positive correlations between inspiratory reserve volume, tidal volume, forced vital capacity, forced expiratory volume (in one second), maximal voluntary ventilation, and success. In contrast, we observed a negative and significant correlation between body fat (%) and success of Iranian elite Greco-Roman wrestlers. Conclusions: Physical fitness traits and lung capacity have a greater potential than anthropometric characteristics in the prediction of Greco-Roman wrestler's success in championship levels.
