Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Work-HIIT will be run as a semester long (16 weeks) work place exercise program at the University of Newcastle, Australia. Session times (before work / lunch time or after work) and locations will be adapted to suit participants (where possible), with group sizes also determined by participant preferences. Participants can become involved individually or as a small group, with multiple sessions offered throughout the week. Work-HIIT will be implemented and evaluated as a randomized controlled trial (RCT). All staff who choose to participate in the study will be randomised into either the intervention group or the wait-list control group (Receives program in Semester 2). Participants will be asked to complete 3 x 10min HIIT exercise sessions per week for the entire semester. The first eight weeks will be supervised by a member of the research team and the following weeks will be participant lead.
All HIIT sessions with include a range of body weight and aerobic exercises. Sessions are designed to enjoyable by encouraging participants to work in pairs of their choice (with one participant undertaking the ‘work’ phase while their partner rests), and as the intervention progresses participants will also be provided with additional elements of choice including: music (playlists), exercise choice during a workout, and choice of workouts. Participants will also be asked to wear a heart rate monitor during sessions so that they can monitor their exercise intensity. Importantly graded exercises to suit all fitness / skill levels will be available.

The feasibility and the effectiveness of the Work-HIIT program for improving a range of health and wellbeing outcomes in adults in the workplace will be assessed using validated measures at baseline (February 2019), 10-weeks (April 2019) and at 6-month follow-up (July 2019). Participants will also be asked to give their opinions about the program via a short evaluation survey at the completion of the program. Participation in this research is entirely your choice and only those participants who have provided explicit written consent will be included in the study. Participants may also withdraw from the study at any time without giving a reason.

Participants use of heart rate monitors and pre/post session evaluations will be used to monitor adherence.

Summary
Brief summary
Work-HIIT will be evaluated using a RCT design (N = 50 workers) to encourage staff to manage sedentary time by attending at least 3 HIIT sessions a week, for a Semester (16 weeks). All HIIT sessions include a range of body weight and aerobic exercises. A range of health and wellbeing outcomes will be assessed using validated measures. Staff at the University of Newcastle who report they are mostly sedentary at work will be recruited (aged 18+ years, and have no existing medical conditions).
