The aim of the study was to see the relative effect of physical activities and lifestyle modification on selected physiological variables among obese individuals. Eighty obese individuals from residential school of Kakching District, Manipur were chosen at random as subjects, and their ages ranging from 15 to 18 years. The subjects (N=80) were divided into four groups, each with 20 obese individuals: experimental group I, experimental group II, experimental group III, and control group IV. Physical activities training was given to the experimental group I (PAG), lifestyle modification training was given to the experimental group II (LMG), and combined physical activities with lifestyle modification training was given to the experimental group III (PALMG) for an hour in the morning for each session. The control group (CG) did not took part in any type of training. The training lasted twelve weeks and followed a set programme (six and seven session in the morning for three experimental group). Before and after the training period, data on selected dependent variables were collected. The collected data were statistically analysed byusing paired ‘t’ test and Analysis of Covariance (ANCOVA) statistics. To find out the paired mean difference, the Scheffe's post hoc test was used. The level of confidence was fixed at 0.05. According to the findings, it is concluded that physical activities, lifestyle modification and combined physical activities with lifestyle modification training had significantly improved mean arterial pressure and peak exploratory flow rate among obese individuals. It is also concluded that combined physical activities with lifestyle modification training had better improvement than isolated physical activities and lifestyle modification training among obese individuals on mean arterial pressure and peak exploratory flow rate.
