The Effect of the Mobile Software Let's Move Program on Changing Sedentary Behaviors of University Students

Sedentary life means a physically inactive, sedentary life and is the fourth largest risk factor for death worldwide. It is reported that 70% to 85% of young people between the ages of age, representing 15.6% of the population of our country\'s population, are sedentary. The Transtheoretical Model(TTM) is an easy-to-use and proven model for changing sedentary life. Therefore, in the first stage of this two-stage research, it was aimed to develop the TTM-based \'Let\'s Move\' mobile software program and to test the effect of the mobile software program developed in the second stage on changing the sedentary life behaviors of university students. The universe of this research will consist of 290 students studying at a foundation university in Istanbul. The sample was calculated using the G-power program (3.1.9.4) program. By taking 10% more of the sample, 97 students in the experimental group and 97 students in the control group will be randomly assigned through the Statistical Package for the Social Sciences (SPSS) program. The TTM-based mobile software program \"Let\'s Move\" mobile software program developed for the experimental group will be applied for 12 weeks. The effectiveness of the program will be evaluated with the pre-test, post-test and follow-up test, the International Physical Activity Questionnaire, the number of daily steps, the smart bracelet, and the TTM sedentary lifestyle TTM Sedentary Life Scales (Stages of Change, Self-Efficacy and Decision-Making scales). At the end of the research, the effectiveness of the \'Lets\'s Move\' mobile software program \"Let\'s Move\" developed in this research in changing the sedentary life will be tested. In addition, it is aimed to increase the number of steps, decrease in sedentary behaviors and make an active lifestyle permanent. All initiatives developed for the TTM sedentary life behavior change stages will be made into a book and the results of the experimental research will be published, contributing and providing evidence to the international literature.
