Abstract: Drag-reducing exercise equipment in the form of a aerodynamic garment may comprise zones with applied textures. Each zone may be associated with properties and characteristics based on the movement of the garment associated with each zone through air during an athletic activity. The texture in each zone may be applied using a variety of methods such as printing. The resulting aerodynamic garment improves the performance of an athlete wearing the aerodynamic garment by reducing the aerodynamic drag experienced during the performance of the athletic activity.

Abstract: A vortex generator might be attached to various types of articles to reduce the drag. For example, vortex generators might be attached to a garment or to adhesive tape. In addition, vortex generators might be attached to various types of athletic equipment. A mapping can suggest placement of a vortex-generator arrangement on an article, as well as prescribe particular vortex-generator arrangements for regions of a person.

Abstract: An aerodynamic garment may comprise zones with applied textures. Each zone may be associated with properties and characteristics based on the movement of the garment associated with each zone through air during an athletic activity. The texture in each zone may be applied using a variety of methods such as printing. Terminal edges of the garment may be treated with silicone or other elastomers to prevent fraying, eliminate stitching, and provide a snug, aerodynamic fit. The resulting aerodynamic garment improves the performance of an athlete wearing the aerodynamic garment by reducing the aerodynamic drag experienced during the performance of the athletic activity.

Abstract: An athletic garment including a panel designed to reduce frictional and pressure drag around an appendage of an athlete competing in a high-speed event, such as running and cycling. The panel is positioned to encircle the appendage, and is provided with regions having different surface texture roughnesses. The leading edge of the panel includes texture designed to enhance the laminar boundary layer, while the adjacent portion of the panel includes texture intended to trip the boundary layer to turbulent flow. The drag-reducing panel may be the cuff of a sock, a sleeve, wristband, a headband, or the like.

Abstract: An end configuration for a bat includes in one embodiment an end cap that has a base that is shaped to fit within the open end of the bat thereby to attach the end cap to the bat. The end cap also includes a convexly contoured end surface that is exposed when the end cap is attached to the bat. The end surface is roughened to reduce the aerodynamic drag when the bat is swung, thereby to increase the momentum of the bat for a given amount of force applied to swing the bat.
