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).

Comparator / control treatment
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.

Study design
Purpose of the study
Treatment
Allocation to intervention
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
