3. Fig. 2
Propulsion patterns. Four classic propulsive strokes are shown: (A) semicircular (SC); (B) SLOP; (C) DLOP; and (D) arcing (ARC). The dark bars to the right of each pattern represent the beginning of the propulsive stroke. The dark bars to the left of each pattern represent the end of the propulsive stroke and the beginning of recovery.
