The aim of this study was to determine the effects 12 weeks Step aerobics program on anthropometric characteristics and body composition in young females. A total of 94 female participants were randomly divided in two groups. The E group subsample consisted of 44 participants (20±0.4 years), who had three Step aerobics program trainings per week and the C group subsample consisted of 50 participants (20±0.6 years), who did not take part in any organized exercise program and only conducted their regular daily activities. The following measurements were used: Body height, body weight, waist size, abdomen skinfold, back skinfold, upper arm skinfold, upper leg skinfold, body fat percentage and muscle mass percentage. Upon the Step aerobics program implementation, there was a body fat reduction by 4.9 % and waist size by 7.7 %, while the muscle mass was increased by 9.4 %. Above mentioned skinfolds showed a reduction (p>0.05) at the final measurement compared to the initial one – abdomen by 25 %, upper leg by 23.7 %, back by 15.7 % and upper arm by 3.5 %. Likewise, there was a body fat percentage reduction by 2.1 % and BMI by 6.4 %. Based on the obtained results, we can conclude that the Step aerobics training is efficient in reducing subcutaneous fat tissue and viscelar fat, as well as in increasing muscle mass.
