Step aerobics represents and efficient and pleasant alternative for achieving fitness. Through its contents, this type of activity contributes to developing resistance, strength of lower body muscles and, not least, coordination.

The purpose of this paper is to note whether – after practicing systemati- cally the aerobic effort using step aerobics programs – muscles become more toned, joint mobility and muscle elasticity increase and whether balance and motor memory improve.

The hypothesis of the paper was the following: by using the step aerobic pro- gram, we can improve the fitness of people who practice this type of physical activity.

The sample within our research comprised 30 women aged between 20 and

35. The study was conducted throughout a year and trainings took place three times a week. The step aerobic sessions lasted for 60 minutes. The tests ap- plied to the research sample were as follows: test for abdominal and arm mus- cle strength and resistance; assessment of spine mobility in anterior plane; balance test; push-ups; and motor memory.


The values of mean and of standard deviation in the test for abdominal and arm muscle strength and resistance improved from 8.2±2.97 in the initial testing, to 13.00±1.94, while the variability coefficient dropped from 36.21% to 14.92%. In the test for joint mobility and muscle elasticity, the values in- creased from 22.8±5.91 to 28.9±4.92, while the variability coefficient de-

creased from 25.93% to 17.05%. Regarding the balance test, values recorded a progress from 2.8±0.78 balance losses to 1.2±0.48, while homogeneity im- proved from 27.85% to 15.70%. As for the test of arm muscle strength, val- ues augmented from 6.3±1.63 initially to 8.8 ± 1.13 in the end, while homo- geneity increased from 25.87% to 12.84%. Furthermore, the values of motor memory testing augmented from 4.3± 1.25 to 7.2± 0.78, while homogeneity from 29.10% to 10.95%.


After processing and interpreting the results, we posit that step aerobic pro- grams contributed to the fitness improvement of female practitioners; thus, the paper hypothesis was confirmed.
