•Metabolic cost of walking was higher in old adults.•Old adults co-contract their muscles around knee joint more compared to young adults.•Muscle co-contraction and metabolic cost were moderately related in older adults.•Co-contraction at the ankle joint was positively correlated with metabolic cost...
