Brief Summary

This study aims to evaluate the effect of human and digital stimulus exercise interventions based on the transtheoretical model on increasing physical activity levels in sedentary office workers. In the study, which is planned to be conducted with a randomized crossover design, participants will be randomly assigned to different intervention conditions (human and digital stimulus). Interventions will be structured in accordance with the behavior change stages of individuals and will be implemented over a certain period of time. Within the scope of the study, physiological indicators such as heart rate variability will be evaluated along with physical activity level. This study is aimed to contribute to the development of evidence-based intervention models to support the physical activity habits of individuals working in an office environment.

Study Groups

Group A-The digital stimulus command

The digital stimulus command:

This group will receive only digital alerts for 4 weeks. Following the washout period, they will participate in a 5-day, 30-minute walking program, accompanied by a researcher, for 4 weeks.

Group Type: EXPERIMENTAL

The digital stimulus command

Intervention Type: BEHAVIORAL

The digital stimulus command: Providing information on the harms of inactivity and sedentary lifestyle on online, digital platforms. The individual will take the HRV measurement in a sitting position for 5 minutes every morning (before consuming tobacco products for smokers) as taught and will send the screenshot of the data to the researcher via WhatsApp. Ensuring that the digital stimulus commands that will remind the activity in line with TTM are followed by reminders sent to the computer screen or mobile phones. Taking a break from sitting when the command "It's time for activity" comes (taking a total of 6 breaks in the working hours of 08:30 - 17:30, 1 every 60 minutes recording the activity as "completed" in the digital diary and survey form) \*Activities of office workers other than the time they spend sitting; Recording the number of steps and activities in the office, its surroundings and in daily life in a digital diary.

5 day 30-minute walking program

Intervention Type: BEHAVIORAL

5 day 30-minute walking program. This group was also defined as the human stimulus group because, in addition to the digital stimulus command, they will be invited by the researcher and will participate in the walking program with the researcher. This group will first receive the activity program and simultaneously will also receive the digital stimulus command interventions.

Group B- 5-day 30-minute walking program

5 day 30-minute walking program. This group will participate in a 30-minute walking program for 5 days a week, accompanied by a researcher, for 4 weeks. Following the washout period, they will receive in the digital stimulus commands for 4 weeks.
