To determine differences in anthropometric, body composition, physiological and neuromuscular markers between elite and amateur female wrestlers, 35 female wrestlers were assigned into 4 groups according to their body mass (light and middle weight) and their competitive level (elite and amateur): light weight (between 49 and 58 kg) in elite (n = 6) and amateur (n = 12) levels, and middle weight (between 58 and 67 kg) in elite (n = 7) and amateur (n = 10) levels. A binary logistic regression analysis was performed to identify which variables better predict female wrestling success. Elite female wrestlers were older (8�10%), had more training experience (27�29%), fat-free mass (3%), maximum strength in absolute and allometrically scaled values (13�33%), maximal muscle power (16�34%), mean and peak power during an arm crank Wingate testing in absolute and allometrically scaled values (17�23%), jumping height (2�9%) and grip (5�13%), and back isometric strength (10�13%) compared with amateur wrestlers (p < 0.05). When the results of the present research and those of a recent study performed in our laboratory with elite male wrestlers were compared, elite women presented lower (p < 0.05) maximum isometric and dynamic strength, muscle power output, and anaerobic metabolism values even when these data were normalized using allometric methods.
