摘要：This study was aimed to examine the relationship of aerobic exercises and body weight reduction among regular physical fitness participants. The researcher used longitudinal experimental research design because participants were tested more than once test and trained for 12 weeks. Twenty subjects were purposively selected as a subject and randomly assigned in high intensity and moderate intensity group; whose age is in between twenty up to fifty years old and their body mass index (BMI) is 25kg/m2 and above. Both groups participated in high intensity and moderate intensity aerobics exercise in their respective groups three days per week for three consecutive months. Pre, during and post tests were taken accordingly to examine the improvements in each variables such as body weight, body mass index, waist circumference, hip circumference and waist hip ratio. Paired sample T-tests indicated a significant reduction of BWt and BMI in both groups of female and male participants at p-value (p < 0.01). Based on the results, it was concluded that both moderate intensity and high intensity aerobics exercise group had a positive effect on body weight reduction. It showed that aerobic exercise has a positive relationship on body weight reduction. Finally, the researcher recommends that regular aerobic exercise is a better means to reduce body weight.
