Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention is a 10 week aquatic training program performed in a dedicated paediatric tertiary hospital hydrotherapy pool at Perth Children's Hospital (PCH). The program is based on high intensity interval training. The properties of water will add resistance to fast paced movement providing simultaneous aerobic and strength training. Participants will participate in a supervised group setting. This program will be offered 3 days/week with participants expected to attend 2 days/week for 10 weeks duration. Adherence to the program will be monitored through the weekly attendance sheets where participants will be asked to report any additional exercise.

The program to improve aerobic capacity and muscle mass will follow previously published parameters utilised in land based exercise training. The 40 - 50 min class will include a warm up; High Intensity Interval Training (HIIT); a cool down and stretches.

During the HIIT phase, participants will exercise at two different intensities. Participants will have an individualised heart rate (HR) goal set by their HR at peak uptake of oxygen (VO2 peak) recorded during a maximal cycle cardiopulmonary exercise test. High intensity will be defined as between 80-95% of VO2 peak HR. Rest is defined as minimal activity. Rate of perceived exertion (RPE) will be recorded. HR will be continuously monitored through a water resistant heart rate device which will be paired to an external monitoring device. Intervals of 60 seconds high intensity activity will be followed by rest of a similar time duration and will be repeated 10 times. Participants will rotate through a circuit of activities each interval. These will be individually adapted to enable the participant to participate within their movement capabilities. Activities include water running, jumping, lower limb kicking and upper limb weights under water.

Comparator / control treatment
Following assessment and randomisation, the control group will be asked to continue with their same care and normal activities of daily living without advice or interaction from the research team. Following a 10 week period, they will be reassessed. Changes in exercise routines during this time will be reported. The control group will be offered exercise prescription advice after the study based on their individual results and the opportunity to participate in an aquatic physiotherapy class post final assessment to assist in exercise knowledge.

Outcomes
Primary outcome [1] 301711 0
Variables related to feasibility of progressing this protocol to a large scale RCT will be reported. Specifically data will be reported relating to:
Recruitment fraction: of those who were invited to participate, the percentage who agreed to participate
Completion of baseline (pre-intervention) assessment: Of those who agreed to participate, the percentage who completed all baseline assessments
Adherence fraction to intervention: Of those randomised to intervention, the number who attended and participated in their nominated classes
Training intensity (in the intervention group only): The percentage who reached their target heart rate during the high intensity intervals, expressed as a percentage of the total number of high intensity intervals completed during the classes
Completion fraction: Of those who agreed to participate, the percentage who completed all aspects of the study
Timepoint [1] 301711 0

Statistical methods / analysis
As this is a pilot study, no inferential statistics will be conducted. The results of the study will be reported using descriptive statistics such as means and standard deviations (parametric data) or medians and interquartile ranges (non-parametric or ordinal data). Categorical data will be reported as frequencies and proportions. A sample size was determined to result in an acceptable level of precision around the point estimate for two outcomes related to feasibility (recruitment fraction and completion fraction). Specifically, it was estimated that a recruitment fraction for this study would be equal to 90% for this protocol to be feasible, without amendment, as a large scale definitive RCT. A sample size of 20 will produce an 80% CI around this estimate that spans from 81% to 99%. Similarly, it was estimated that the completion fraction for this study would be 75% for this protocol to be feasible, without amendment, as a large scale definitive RCT. A sample size of 20 will produce an 80% CI around this estimate that spans from 63% to 87%.
