Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Subjects will be randomised into a progressive resistance training (PRT) or sham-exercise group. The PRT group will train at 80% of their peak strength, using Keiser pneumatic resistance machines, and progress approximately 3% per session. Strength will be re-assessed fortnightly. Exercises will target muscles around the hip and knee. The sham-exercise group will train on the same equipment as the PRT group except hip adduction, but without added resistance or progression. Both groups will train 3 days per week for roughly 45 minutes for 6 months.

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)
Randomisation of subjects will be carried out using opaque envelopes with their exercise group assignment inside. The label in the envelope will only state Group A or Group B. Researchers will not disclose to subjects which group is hypothesized to be the preferential group.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Using randomisation software from www.randomization.com. Subjects will be stratified according to WOMAC scores (cut-off WOMAC difficulty score of 53) and whether or not they are currently taking and/or have taken (last 6 months) either glucosamine or chondroitin at any dosage (yes/no)
Masking / blinding
Blinded (masking used)
