The exercise is fun and relatively low cost, Zumba can also increase the strength of respiratory muscles so as to improve lung function and capacity Aim: To observe the effect of Zumba routine exercise on peak expiratory flow rate in young female Method: The study was an observational analytic using cross sectional approach. Subjects were participants of Zumba routine exercise cathegorized to <8 weeks and ≥8 weeks exercise periods. PEFR was measured by mini-Wright peak flowmeter. Correlation between the period of Zumba exercise and PEFR was analyzed using Spearman’s test. Result: From the 24 subjects, the mean of PEFR in participants who were conducted Zumba exercise for <8 weeks was 345.42 ± 30.19 L/min with the lowest score was 300 L/min and the highest was 400 L/min. The PEFR mean of subjects who experienced Zumba exercise for ≥8 weeks was 437.92 ± 19.59 L/min with the lowest was 400 L/min and the highest 465 L/min. The Spearman’s test showed a very strong degree of positive correlation between period of Zumba exercise with PEFR (r=0,86; p=0,000) Conclusion: The study found the differences between the mean of PEFR in subjects who did Zumba regular exercise for <8 weeks and ≥8 weeks. This study also showed very strong positive correlation between period of Zumba exercise with PEFR Keywords: Zumba exercise, peak expiratory flow rate, physical exercise *
