Joint Torque and Mechanical Power of Lower Extremity and Its Relevance to Hamstring Strain during Sprint Running

Table 1

Comparison of peak joint extension-flexion angular velocity (v_PA) between three joints during a gait circle.

	Hip joint		Knee joint		Ankle joint
	Extension	Flexion	Extension	Flexion	Plantarflexion	Dorsiflexion
vPA (rad/s)	9.32 ± 1.15	9.95 ± 1.02^†	11.64 ± 1.11	9.57 ± 0.95^†	16.20 ± 1.97	11.51 ± 0.96

^,†Significantly different from ankle plantarflexion and dorsiflexion, respectively.
