The Effect of Low-Impact Aerobic Dance Exercise Video on Cardiovascular Endurance, Flexibility, and Concentration in Females With Sedentary Lifestyle

Abstract

The study purpose was to prove the effectiveness of a low-impact aerobic dance exercise video on cardiovascular endurance, flexibility, and concentration in women with a sedentary lifestyle.
 Materials and methods. This study used the Pre-Experimental method with a One-Group Pretest-Posttest Design research design. Total of 18 females aged 18–20 y.o., body mass index (BMI) 19 kg/m2 – 24 kg/m2, normal systolic and diastolic blood pressure, normal resting heart rate, oxygen saturation (SpO2) 96% – 100% participated in the research. Low-impact aerobic dance exercise was done using video for 30 minutes/exercise session with an intensity of 75% – 85% HRmax with a frequency of 3 times/week for 6 weeks. Measurement of cardiovascular endurance was done using the Multi-Stage 20-m Shuttle Run Fitness Test, flexibility was measured with the Sit and Reach Test, and concentration was meassured with the Grid Concentration Test. The statistical analysis technique used the Paired Sample T-Test with a significance level of 5%.
 Results. The results showed the average cardiovascular endurance of the pretest vs. posttest (28.13 ± 4.80 vs. 30.52 ± 0.88 mL/kg/min (p ≤ 0.001)), mean flexibility of pretest vs. posttest (17.79 ± 4.72 vs. 18.75 ± 5.02 cm (p ≤ 0.001)), mean concentration of pretest vs. posttest (7.39 ± 2.38 vs. 9.11 ± 2.45 score (p ≤ 0.001)).
 Conclusions. Based on the results of the study, it was concluded that a low-impact aerobic exercise dance video performed with a frequency of 3 times/week for 6 weeks increased cardiovascular endurance, flexibility, and concentration in adolescent girls with a sedentary lifestyle.
