Study type
Interventional
Description of intervention(s) / exposure
High intensity progressive resistance and impact loading exercise program (HiRIT)

- Two training sessions of 30-40 minutes per week on non-consecutive days for 6 months 
- Group exercise program with a maximum of 8 participants per class and trainer, led by an experienced instructor (the instructor is either an exercise scientist trained in power lifting or an exercise physiologist)
- The program consists of three weight lifting exercises and one impact exercise
- Load and intensity of the lifting and impact exercise are gradually and individually increased
- Five sets of five repetitions at 80-85% 1RM are performed for each of the three lifting exercises

- The classes take place at The Bone Clinic, Coorparoo, Brisbane, QLD 
- Adherence is tracked by the instructor and the study participants. Participants are given an exercise diary to report the sessions attended, weights lifted, any muscle soreness, injuries, falls and changes in medication, which the instructor monitors.

Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Stratified block randomisation using a randomisation table created by computer software. Stratification variables were sex (male, female), age (50-64 years, 65+ years), joint(s) with most severe OA (knee, hip)
Masking / blinding

Efficacy
Statistical methods / analysis
Statistical analyses will be performed using SPSS statistical software. In all analyses a p-value of 0.05 (two-sided) will be considered a threshold for statistical significance.
Descriptive analyses will be run for participant characteristics and biometrics. Repeated measures ANCOVA will be conducted to examine treatment effects on all outcome variables adjusting for any variables that differ between groups at baseline. Intention-to-treat analyses will be conducted along with per-protocol analyses to examine specific outcomes of participants completing the full 6 months of training with at least 80% compliance.

Summary
Brief summary
Osteoarthritis (OA) of the knee and the hip is an important health issue in the senior population since it causes chronic pain, reduces physical functioning and has a negative effect on quality of life. Different types of exercise intervention programs have shown a beneficial effect on OA symptoms. However, only few studies tested the effect of high load resistance training in OA patients. Observational data from The Bone Clinic suggests that our bone exercise program, consisting of high load resistance training plus impact weight bearing is not only beneficial for bone but also for OA symptoms. This study aims to formally test the effect of our bone exercise program in combination with balance exercises on pain, physical function and quality of life in people with knee or hip OA.
