Relationship between Lower Limb Angular Kinematic Variables and the Effectiveness of Sprinting during the Acceleration Phase

Figure 3

Instantaneous changes in the angular velocity in the area of lower limb joints with respect to specific axes during a 30-meter sprint acceleration phase along a straight line for the left limb (continuous line) and right limb (dashed line). Continuous or dashed thin grey lines were denoted ±SD for the left and right limb, respectively.

(a) Hip flexion-extension angular velocity

(b) Hip abduction-adduction angular velocity

(c) Hip internal-external rotation angular velocity

(d) Knee flexion-extension angular velocity

(e) Ankle dorsi-plantarflexion angular velocity

(f) Ankle inversion-eversion angular velocity

(g) Ankle abduction-adduction angular velocity
