Supplementary Figure 1 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' ankle joint A) angles, B) moments, and C) powers versus % of a stride starting at heel-strike for each walking speed on each slope. Ankle angles are presented for the entire stride and ankle 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).
