    ZUMBA FITNESS TO IMPROVE BODY COMPOSITION & PHYSICAL FITNESS IN INACTIVE EMPLOYED FEMALES

    Abstract

    PURPOSE: to investigate the effect of two exercise interventions based on Zumba Fitness and Bodyweight training on body composition and physical fitness in inactive employed females. METHODS: A total of 56 inactive employed female participated in this study (38.7+1.00-yr). The sample was randomly divided into two groups: Zumba Fitness (Z, n=28, 1hour/per session) and Zumba Fitness + 20 minutes of Bodyweight training (ZB, n=28, 1.33 hours/per week), including both 3 days per week. Body composition (BMI, Fat mass, muscle mass and 6-skinfold) and Physical Fitness through Alpha Fitness Battery for adults: Motor fitness (one leg stand test), Musculoskeletal fitness (shoulder and neck mobility test, jump and reach test, hand-grip test and sit up test), and cardiorespiratory fitness (2-km test) was analyzed at baseline and 16-weeks post-interventions. A Factorial Anova was used to analyze the effects and interactions of the type of intervention and the measure moments on body composition and physical fitness variables. RESULTS: The type of intervention showed a significant effect only in the case of rest heart rate after 2-km test, which was lower in ZB group compared with Z group (MD=9.53.45 bpm, p=0.011). However, both interventions showed a significantly effects (p<0.05) on the majority of the studied variables compared baseline with post-intervention. BMI, fat mass, muscle mass, 6-skinfold, one leg stand test, hand grip test, and 2-km test, enhanced for both group after interventions, however, Z group reached the higher improvements. Shoulder and neck mobility test, sit up test and the Heart Rate post- 2km test, only improved after ZB intervention. CONCLUSIONS: Zumba Fitness intervention could improve the body composition and physical fitness in inactive employed females. Twenty minutes plus of bodyweight training seem not to generate changes in the variables studied.
