BRIEF NAME: High intensity exercise - "F45"

PROCEDURE: Participants will be asked to attend four F45 classes per week based on their own personal schedule. These classes will be provided free of charge as part of this study. Two of the four classes attended will have a cardiovascular focus and the other two a strength training focus. All classes will be the standard 45 minutes (as per F45 structured training protocols).

For the purpose of this study, 'high intensity' has been defined according to the guide provided by F45, which is 75% of heart rate maximum (calculated by 206.3-[0.711 x age]). This is constantly measured by a heart rate monitor that is worn throughout the 45 minute class.

Participants will attend general F45 classes that will also be attended by members of the public. These classes are not designed specifically for this trial, but instead for a general F45 population. Class sizes differ based on the number and difficulty of exercises, as well as the equipment required. Class sizes range from a maximum of 27-36 per class; however, class sizes may be smaller depending on attendance numbers.

The exercises in each class vary, but the classes use a format of approximate 30-40 seconds of work and 10-20 seconds of rest for all exercises. Examples of exercises in the 'cardiovascular' classes include: burpees, skipping, and stationary cycling. Examples of exercises in the 'strength' classes include: dead lifts, dumb bell bench press, and pull ups.

The classes are structured sessions which are designed by exercise scientists. The exercises in each class are projected onto television screens throughout the gym. Certified fitness instructors supervise participants to ensure fidelity to the set exercises.

Adherence to the exercise program will be done in two ways: first, an attendance checklist will be taken by F45 and provided to the research team; and second, participants will be phoned weekly and asked to provide their attendance rate.

Participants in the exercise group will perform the exercise intervention for 45 sessions over 12 weeks in total. A ‘ramp up’ process will be used, where women are asked to do two sessions for the first week, then three for the second week before moving to the 4/week for the remainder of the 10 weeks (total 45 sessions).

The comparator will be a wait-list control. Participants in this group will be instructed to continue their daily routines as normal for a 12-week period. Once the 12-week wait-list period is complete, women will begin the same exercise intervention as the F45 group.

Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Castor EDC provides built in allocation concealment. PI Chalmers and PI Armour will have the secure login details for Castor EDC. Once a participant is eligible and has provided consent, either PI Chalmers or PI Armour will login to Castor and randomise the participant. An email will be sent to both PI Armour and PI Chalmers with the group allocation and Study ID. The research assistant/clinical trial co-ordinator will not have access to the randomisation function and will be unable to determine which group participants are allocated to.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomisation sequence will be created using the online randomisation service provided by Castor EDC.

Statistical methods / analysis
Baseline measurements will be compared via t-test or Fisher’s exact test to explore differences between groups at baseline. As participants will be randomly allocated to a group, we anticipate that groups will be similar at baseline.

Due to the feasibility nature of the study, inferential statistics of outcome measures is not appropriate. Outcomes will be presented as mean (SD) and 95% confidence intervals for the following, by group:
- Pre-intervention/post-intervention/follow-up:
• BMI
• Body composition (bioelectrical impedance analysis)
• Hip/waist ratio
• Multi-stage fitness test
• Menstrual Pain Diary
• Pelvic Pain Impact Questionnaire
• Analgesic use

- During intervention:
• Menstrual Pain Diary
• Pelvic Pain Impact Questionnaire
• Analgesic use
• Exercise compliance

Summary
Brief summary
The aim of this project is to determine the feasibility of running a fully-powered randomised controlled trial on the use of high intensity exercise in reducing period pain (dysmenorrhoea). This project will use 30 women aged 18-30 who have primary dysmenorrhoea (period pain not explained by an identifiable pathology). Women will be randomly allocated to an 'Exercise' group or 'Wait-list Control' group. Women in the 'Exercise' group will undertake four high intensity exercise classes per week for 12 weeks total. Both groups will complete a Menstrual Pain Diary during each menstrual period over the 12 weeks. Other outcome measures will include pelvic and period pain scales, anthropometric measurements, fitness level, exercise compliance, analgesic use over the 12 weeks, and any adverse events experienced. These outcomes will assist in determining the feasibility of an appropriately-powered RCT to explore the effectiveness of high intensity exercise on primary
dysmenorrhoea.

Public notes
Exercise is increasingly being used to treat a range of chronic pain conditions, including dysmenorrhoea, and is indicated in clinical guidelines for the management of dysmenorrhoea. A small number of studies have demonstrated that various types of exercise, including cardiovascular, strength, and flexibility, can reduce pain levels in adolescents and women with dysmenorrhoea. However, no information is provided in these guidelines on the specific frequency, intensity, time, or type of exercise that should be prescribed. Randomised controlled trials and systematic reviews across a number of healthy and chronically diseased cohorts have shown that HIIT can offer superior changes in physiological, performance, and health-related markers compared to other types of exercise; however, no studies have investigated the potential effect of HIIT on primary dysmenorrhoea.
