Evaluation of Changes in Body Composition and Efficency of Women Under the Influence Of 4-Month Step-Aerobics Training

Abstract

The aim of the study was to determine changes in body composition and efficiency of a group of women subjected to 4-month step-aerobics training. Issues of the research have been defined by the question: Were the body composition and efficiency of the researched women changed under the influence of step-aerobics, and if so, how big those changes were? The study group consisted of 30 women aged 23-38 years, regularly attending the fitness classes of step-aerobics three times a week, lasting 45 minutes. Based on the measurements of height and weight BMI was calculated. Body composition was determined using the analyser TANITA. Cooper test was also conducted. Its purpose was to determine the maximum aerobic capacity (i.e.Oxygen uptake VO2max), which is a determinant of physical condition. Based on the analysis of the results, the following conclusions were drawn: 1.Step-aerobic has a positive effect on the body composition. The period of four-month training with frequency of 3 times a week caused: body weight loss by 3.86%, decrease of BMI values on average by 3.83%, reduction of the body fat levels on average by 17.75%, increase of muscles mass on average by 2.21%. 2. Participation in class step-aerobics brings significant benefits associated with the level of efficiency. The period of four-month training with a frequency of 3 times a week caused an increase of women efficiency participating in this form of female fitness, on average by 17.31% (Cooper test results).
