Knee abduction moments of normal weight, overweight, and obese participants in gait, cycling, and elliptical training

Internal knee abduction moments affect mediolateral distribution of tibiofemoral loads and, thus, are likely related to the development of knee osteoarthritis (OA). Four normal weight (NW), overweight (OW), and obese (OB) participants performed gait (G), cycling (C), and elliptical (E) training experiments. Kinematics were recorded and kinetics were calculated by a 12-camera motion analysis system with Cortex software. Maximum knee abduction moments were higher in G than C (p< 0.001) and E (p< 0.001) for NW, OW, and OB groups and suggest that cycling and elliptical training are preferred weight loss exercises.
