... a wide range of heights. The kangaroo rats in this study reached maximal jump heights up to ∼9-times hip height. Net joint work increased significantly with jump height at the hip, knee and ankle, and decreased significantly at the metatarsal–phalangeal joint. The increase in net work generated by each...

... joint work done at the ankle ( Fig. 4 ). Positive ankle work decreased by 0.413 J kg −1 (22%) while negative ankle work decreased by 0.147 J kg −1 (18%; P =0.0001 and P =0.0008, respectively). Positive and negative joint work for the knee and hip were not statistically different between the two...

..., mechanical energy was generated at the hip, knee and ankle, and the net work at each of these joints increased dramatically with speed ( P <0.05). The greatest increases in positive joint work occurred at the hip and ankle. During downhill running, mechanical energy was decreased in two main ways: goats...
