Plain English summary of protocol
Background and study aims
Women are more inactive when compared to men and this is a concern as physical inactivity puts women at risk of adverse health effects. Women's tend to drift into a less active lifestyle starting in their 20s, during their transition from school to the workplace. Due to the unique and varied challenges faced by working women, places of employment is an ideal avenue to implement programs to increase physical activity. The aim of this study is to evaluate the effectiveness of incremental workplace exercise intervention designed to increase fitness level among women with low physical activity
Who can participate?
Women employee of University Malaya Medical Center who has low physical activity level, between the age of 25 and 49, and who have no limitation to exercise
What does the study involve?
Seventy women will be randomly assigned to either an intervention group (exercise) or a control group (pedometer). In the intervention group, participants will aim to meet the 150 minutes of moderate-intensity exercise a week. Participants will have two familiarization sessions to exercise in the first week. In the next eight-weeks of the active phase, participants will perform two supervised exercise video sessions weekly. Additional moderate-intensity exercise sessions are encouraged at participants' own time. In the following eight-weeks maintenance phase, participants will continue to meet and maintain the exercise goal on their own.
In the control group, participants will aim to reach 10,000 steps/day. Each participant will receive a pedometer which will have to be worn for the whole of the waking time during the study period (16 weeks). In the first eight weeks of the active phase, participants will be guided to build on their total steps a day to reach the 10,000 steps/day goal. In the following eight weeks of the maintenance phase, participants will continue to maintain and reach their goal on their own. Participants will need to log in their daily steps on an online website.
For both groups, participants required to adhere to the healthy eating plate guide to eating choices with ½ portion for vegetables and fruits, ¼ portion for whole and intact grains, and ¼ portion for protein.
Participants will go through several fitness assessments and answering several exercise-related behaviour questionnaires at baseline, week-nine and week-17, post commencement of the study
What are the possible benefits and risks of participating?
Possible benefits include improvement of physical fitness and several aspects related to behavioural changes related exercise (see primary and secondary outcomes and hypotheses). Potential risks are those intrinsically associated with exercise, such as potential injuries. However, this is unlikely to occur as all sessions will be closely supervised by qualified professionals
Where is the study run from?
University of Malaya Medical Center, Malaysia
When is the study starting and how long is it expected to run for?
February 2019 until July 2021 (updated 24/02/2020, previously: February 2020)

| Scientific title | Effects of a 16-week incremental workplace exercise program on fitness level among female workforce with low physical activity |
| Study objectives | Intervention group will see a bigger improvement gains in fitness level as compared to control group |
| Ethics approval(s) | Approved 0201/2019, Research Ethics Committee of the Universiti Teknologi MARA (UiTM) (Aras 3, Bangunan Wawasan, 40450 Shah Alam, Selangor, Malaysia; +603 5544 2094; irmiuitm@salam.edu.my), ref: 600-IRMI (5/1/6) |

| Intervention | Intervention group consists of incremental exercise and control group consists of incremental steps/day. The total study period for this study is 16 weeks, including eight-week active phase and eight-week maintenance phase. Consented participants will be randomly assigned to either the intervention group or control group, using a systematic allocation method. This allocation will take into account perceived commitment, and working schedule. A single-blinded method will be used where outcome assessors and statistics analyzer will be blinded. Intervention group: Participants is in this group will be instructed to gradually achieve and maintain 150 minutes of moderate-intensity physical activity (PA) per week. Participants will go through two sessions of exercise familiarization in week one. In the following eight-weeks of the active phase, participants are required to attend two observed exercise sessions and will be encouraged to increase their moderate-intensity exercise sessions to 150-minute a week. In the following eight-weeks maintenance phase, participants will be encouraged to continue their PA without push encouragement. For the study duration, participants will self-report their additional exercise sessions to the researchers. Control group: This is an active control group. Participants will wear a pedometer daily during their waking time for a total of 16 weeks. In the first eight-weeks of active phase, participants will receive guidance to increase their daily steps by 10% with the aim to reach 10,000 steps/day. In the following eight-weeks maintenance phase, participants will continue to reach and maintain their 10,000 steps a day without guidance. Participants are required to log their daily steps into an online system. For both intervention and control groups, participants are required to adhere to the healthy eating plate guide to eating choices with ½ portion for vegetables and fruits, ¼ portion for whole and intact grains, and ¼ portion for protein |
| Intervention type | Behavioural |
| Primary outcome measure | Cardiorespiratory fitness assessed using an estimated maximal oxygen uptake using the Åstrand-Rhyming cycle ergometer test at baseline, week-9 and week-17 post commencement of the study |
| Secondary outcome measures | Fitness assessment: 1. Muscle strength fitness is assessed using three repetition maximum (3RM) test for chest and leg press at baseline, week-9 and week-17 post commencement of the study 3. Muscle endurance fitness is assessed using prone plank technique at baseline, week-9 and week-17 post commencement of the study. 4.
