Lack of physical activity and an uncontrolled diet cause excessive weight gain, which leads to obesity and other metabolic disorders. A sedentary lifestyle poses a threat to individuals’ health because it can lead to an increase or progression in the risk of hypertension, obesity, muscle weakness, postural defects, and lean body mass. Measurement, assessment and monitoring of BC in humans have been three of the main challenges for health sciences professionals. Effective weight management strategies consider not only weight loss toward but also the maintenance of a healthy body weight over time. The researcher was interested in assessing the effects of twelve weeks’ aerobic dance training program on body composition of young women. The body composition was assessed using waist to hip ratio and skinfold. The study was a one group pre-test post-test design with thirty subjects. The subjects selected for the study were post-graduate female students studying during 2017-18 at Kuvempu University, Shankaraghatta. Their age ranged between 20 to 25 years. All the subjects were residents of women’s hostel within the main campus. The criterion measures of body composition were waist to hip ratio and skinfold measurements at four sites. Descriptive statistics like mean and standard deviation were employed on the raw scores during pre and post-test situations. The differences between mean scores were calculated using ‘t’ test for paired samples. Findings of the study are discussed in detail. Within the limitations of the present study, it is concluded that the exercise intervention in the form of aerobic dance performed for twelve weeks is effective in reducing body fat in young women.
