Swimming Technique Concepts: Development of an Optimal Model For Technique- Part 5

Body Base of Support For Butterfly
by Rod Havriluk

The first three articles of this series (Swimming World July, August and September) addressed concepts related to a body’s position in water that minimizes swimming resistance. Specifically, body size and shape (Part I), body rotation (Part II) and head position and motion (Part III) were each presented as essential elements to control for optimizing swimming technique. All of these factors help to minimize resistance, but also help to make a stable “base of support” to maximize propulsion.

The most recent article (SW December) introduced a new approach to using a well-established concept for land-based activities: the “base of support” (BOS). The BOS is fundamental for addressing body stability. In a terrestrial activity like running, the BOS refers to the contact of a limb extremity (such as the foot) with the ground (the environment).

During a typical butterfly stroke, the continuously changing angle of the torso seriously compromises the stability of the shoulder (the body base of support). An optimal technique model maintains a level torso with minimal vertical motion of the shoulder, so a swimmer can benefit from more propulsion, easier control of arm movements and faster swimming velocity.
