Competitive strokes have been widely analysed, while kinematics of coordinative drills, used to train or teach swimming techniques, have been scarcely studied. The aim of this work is to evaluate the differences in the intra-cycle hip velocity among freestyle swimming drills. Thirteen national and regional level swimmers performed five 25-m freestyle trials, using different stroke drills in a random order. The propulsive phase of each stroke was analysed. Mean and peak (one or two) velocity were obtained, and their corresponding phase percentage. The first peak recorded corresponded to the inward movement, which coincided with the final propulsion or downward movement of the opposite arm. The second one corresponded to the final backward-upward movement, which, is in most cases, the highest value of velocity while the non-propulsive arm is extended horizontally in front of the shoulder. The freestyle stroke drills applied to teach or train different types of inter-limb coordination reduce the mean and peak values of intra-cycle hip velocity while the percentage location of peak hip-velocity value during the underwater stroke phase is similar without significant statistical differences.
