摘要:The research compares the effects of two HI-LO models of aerobic training (aerobic dance) on the cardiovascular fitness of 29 women ages 25 to 30. The experimental program was carried out with the assistance of two experimental groups (E1: n = 15 and E2: n = 14). The "A" HI-LO aerobic dance model was realized over a period of 8 weeks, with fifty-minute training sessions three times a week. The "B" HI-LO aerobic dance model was realized over a period of 8 weeks, with 35-minute training sessions five times a week. The exercise intensity of the A and B models was the same (60-75% of the maximum). Cardiovascular fitness was evaluated by means of the following parameters: resting heart rate, heart rate under strain, systolic arterial blood pressure, and diastolic arterial blood pressure, absolute value of maximal oxygen uptake and relative value of maximal oxygen uptake. The data from the initial and final measurings was processed by means of a canonical discriminant analysis. Between the groups (E1 and E2) at the initial and final measurings there was no statistically significant difference regarding the studied variables. The effects of both of the HI-LO aerobic dance models are, on the basis of the results, statistically significant in their entirety. The variables which contributed in particular to the discrimination of the initial and final measuring results for the E1 and E2 groups are: resting heart rate and the relative value of maximal oxygen uptake. It was concluded that the effects of the two HI-LO aerobic dance models on cardiovascular fitness are equally beneficial, if aerobic dance is practiced over a longer period of time with training sessions three times a week, or if it is practiced five times a week for a shorter period of time, on condition that the intensity of the exercise remains the same.
