Interventional
Description of intervention(s) / exposure
An information/orientation session will be held at week zero in a place that is most convenient for participants on the University campus. In this session, the principal researcher will welcome participants to the program and explain the study objectives, benefits and risks in details. Then, he will take baseline anthropometric measurements (weight and height) and waist circumference using standardised methods. Also, participants will be asked to complete a survey of 25 questions about their sitting and standing behaviours at work and to assess demographic characteristics. At the appointment, participants will be given accelerometers, elastic belts, wearing instructions and log-sheets. The principal researcher will show participants how to wear the accelerometer and how to complete the log sheet provided. Participants will be asked to wear the accelerometer on the hip during waking hours for five consecutive days. Additionally, they will be asked to record their sleeping and non-wear time (whenever they are in water) during these five days in the log-sheet provided. During this week, participants will receive daily text-message reminders to wear the accelerometer.

Six days later, there will be another appointment with participants, where they will return the accelerometers and the log sheets. Then the principal researcher will ask participants about their physical activity and sleeping patterns during the previous week. In this appointment, the reminder software will be installed on the intervention group participants' office computers and a log-sheet to track their breaks will be provided. The principal researcher will explain how they can adjust the timing of reminders based on their own preference and how to record their breaks in the log sheet provided. This log-sheet will be collected from each participant at the end of each week during the program.

The intervention will run for 12 weeks and does NOT include any sport or fitness training.

The program includes:
1. Installing a reminder software on participants’ office computer. This software will remind them to break up the time they spend sitting at work. Reminder to break should occur every 30 minutes to one hour based on participant preference.
2. Receiving weekly text-message support. These text-messages will be provided with ideas and techniques that will help participants to break up the time they spend sitting and engaging in more healthy habits.
3- A log-sheet to record and track their active breaks.

After the 12-week program, participants will again meet with the principal researcher. Similar to the first appointment at week zero, the principal researcher will take participants’ anthropometric measurements weight and waist circumference using standardised methods. Also, participants will be asked to complete a survey of 25 questions about their sitting and standing behaviours at work. Participants will be given accelerometers, elastic belts, wearing instructions and log-sheets. Participants will be asked to wear the accelerometer on the hip during waking hours for five consecutive days. Additionally, they will be asked to record their sleeping and non-wear time (whenever they are in water) during these five days in the log-sheet provided.

Six days later, participants will have another appointment with the principal researcher. They will be asked about their physical activity and sleeping patterns during the previous week with additional process evaluation items to evaluate their program satisfaction. The appointment will be held in a place convenient for participants on the Univesity campus. Gift vouchers will be given to participants as an appreciation for participating in the data collection at this session as well.

Primary outcome [1] 304254 0
Change in minutes of sedentary behaviour using ActiGraph GT3X accelerometers (ActiGraph LLC, Pensacola, FL, USA) and the 7-day Physical Activity Recall questionnaire (7-day PAR).
Sedentary behaviour is any waking behaviour characterized by an energy expenditure less than or equal to 1.5 metabolic equivalents (METs), while in a sitting, reclining or lying posture.
Timepoint [1] 304254 0
Five consecutive days at baseline (prior to intervention commencement, T0) and five consecutive days after completion of 12 week intervention (T1)
Primary outcome [2] 304255 0
Changes in self-efficacy construct from Social Cognitive Theory (SCT) using reliable questionnaire adapted from previous physical activity and sedentary behaviour literature (Hadgraft et al., 2016).

Eligibility
Key inclusion criteria
Inclusion criteria:
Apparently healthy, adult, male academics and/or professional staff from two nominated faculties at a public university in Saudi Arabia and who own and use a mobile phone.

A “good health status” will be determined using the revised physical activity readiness questionnaire (PAR-Q) (Thomas, Reading & Shephard, 1992) by phone. PAR-Q is considered the standard physical activity screening tool for eligibility.
The recommended protocol in the PAR-Q+ will be followed. Eligible participant should answers “no” to all questions in the page 1 from the PAR-Q+. If someone answers “yes” to a question in the page 1, he will be asked the questions on pages 2 and 3. If he answers yes to a question on page 2 or 3, he will be asked to complete the specially designed online screening and exercise recommendations program - the ePARmed-X+ at www.eparmedx.com. This will inform if the participants can still participate or he should visit a qualified exercise professional or his family physician to get a clearance to participate. In this case, the researcher will ask the participant to provide the clearance in order to participate in the study.

Purpose of the study
Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation is not concealed. The researcher will be aware of participants allocation.
To reduce the risk of contamination a cluster randomised controlled design was used. Participants will be allocated to either intervention or control group based on their cluster, which is their faculty at the main campus of a public university in Saudi Arabia. Based on the results of the previous need assessment study, two faculties within the main campus in a public university in Saudi Arabia that have a similar landscape and building structure were nominated.
These two faculties were allocated at random to either receive the intervention or to be the control group by the lead investigator witnessed by the chief investigator (using a simple randomisation (coin-toss).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
As explained before a simple randomisation (coin-tossing) was performed to allocate the two faculties to control and intervention.

Efficacy
Statistical methods / analysis
The primary outcome is change in sitting time between baseline and follow-up. A previous 12-week RCT by Schuna Jr et al. (2014) showed a reduction in sitting time of 28.8 minutes/8-h workday with a SD of 75.14. A recent systematic review and meta-analysis of workplace intervention to reduce sitting among office workers, reported average reductions in workplace sitting of 79 min/8-h workday (Chu et al., 2016). Thus, this study will be powered to detect a reasonable 60 minutes change between control and intervention groups. 26 participants per group is required to detect this difference with 95% confidence (a = 0.05) and 80% power. To account for attrition this sample size was then inflated by 25%, therefore, the final sample size is 33 per group with 66 participants in total. This calculation was performed using the package Power and Sample Size (version 3.1.2).
