Design outcomes

Secondary

Measure	Time frame
1. Muscle activation data is measured using surface electromyography (EMG) at all assessment sessions (week 0, week 6 and week 10) and first and last training sessions (week 1 and week 6). 2. Knee osteoarthritis severity is measured using Oxford Knee Score at baseline assessment session (week 0). 3. Free-living energy expenditure is measured using a wrist-mounted physical activity monitor (GENEA Active) and weekly activity logs from week 0 to week 5.	—

Primary

Measure	Time frame
1. Knee loading parameters (e. g. KAM, KFM and KAM impulse) are measured using the forceplates and motion capture system at all assessment session(week 0, week 6 and week 10), and all training sessions (week 1-6) in the intervention groups. 2. Gait pattern parameters (e. g. foot progression angle, step width, step length) are measured using motion capture system at all assessment session(week 0, week 6 and week 10), and all training sessions (week 1-6) in the intervention groups. 3. Knee pain is measured using Numeric Rating Scale (NRS) at all assessment sessions (week 0, week 6 and week 10). 4. Functional ability is measured using WOMAC questionnaire at all assessment sessions (week 0, week 6 and week 10).	—
