Supplementary Figure 3 from The contributions of ankle, knee and hip joint work to individual leg work change during uphill and downhill walking over a range of speeds

Ensemble averages of 10 strides for 20 subjects' hip joint A) angles, B) moments, and C) powers versus % of a stride starting at heel-strike for each walking speed on each slope. Hip angles are presented for the entire stride and hip joint moments and powers are presented for the stance phase only (0–70% of a stride). Each column represents a different slope from −9° (left-most column) to +9° (right-most column)
