Conditions
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.
Interventions
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 lif
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.

Exclusion criteria
- walking aids - malignancy or receiving radiation or chemotherapy - current regular physical activity that includes strength training or intention to start any kind of exercise program during the 6-month study period - medications known to affect bone health (e.g. bisphosphonates, denosumab, hormone therapy, vitamin D injections) - conditions know to influence bone health (e.g. Paget’s disease) - conditions prevention completion of either exercise program (e.g. spinal cord injury, nerve disorder, uncontrolled cardiovascular disease) - inability or unwillingness to attend the supervised training program or the home program if assigned - planned absence (e.g. holidays) of more than two weeks during the 6-month study period. - three or more ionising radiation exposures in the previous 12 months (exceptions apply see below) Participants who have had three or more x-ray examinationionising radiation exposures in the previous 12 months and wish to volunteer for the study regardless before enrolmentmust have to si sign an additional consent formstatement, confirming that they recognise and consent to the requirement agree to undergo baseline and follow-up DXA scanning in spite of other recent ionising radiation-based scanning exposure
