Lack of physical activity and unhealthy lifestyles is no stranger to the current millennial generation. so many of them are gaining weight until they are obese. One of the characteristics of obesity is an increase in body fat percentage. Physical activity is a good way to reduce body fat percentage. The aim of the study was to examine physical activity trends in the millennial generation to decrease body fat. It used a pre-posttest two treatment design, with 22 samples of obese women, and divided into aerobic dance group and Zumba group. It was conducted 3 times in a week along 12 weeks, with intensity of 65% -85% based on maximum heart rate. The result of this study showed that aerobic dance and Zumba had an effect on body fat percentage.

This research is motivated by the low participation of female students in physical education learning (Goodyear, Casey, & Kirk, 2014). The purpose of this study is to determine the increase in participation and manipulative learning outcomes of female students in physical education in fifth grade students of SDN 053 Cisitu, Bandung City 2019/2020. Therefore, researchers are interested in conducting a study so that participation and manipulative learning outcomes of female students can increase. In this study, researchers used an experimental research method with the research design used was The Matching-Only Pretest-Postest Control Group. The research instrument used the PEPAS -Purposes for Engaging in Physical Activity Scale questionnaire and the manipulative learning outcomes assessment sheet. Based on the results of the analysis it can be concluded that there is no difference in the effect of the three cooperative learning strategies on the participation of female students, so it can be said that the three strategies have the same effect in increasing the participation of female students. However, on the results of students' manipulative learning there are differences in the effects of these three cooperative learning strategies, where the STAD strategy provides the best effect on manipulative learning outcomes for female students, followed by the TGT strategy and the Jigsaw strategy.
