These lightweight projectiles, typically constructed from polyurethane or similar materials, are designed for use with pitching machines in various sports, particularly baseball and softball. Their reduced weight and softer composition compared to traditional baseballs or softballs minimize the risk of injury during practice, making them ideal for training younger athletes or honing specific skills without the fear of hard impacts. They vary in size, color, and density, catering to different age groups and training objectives.
The safety advantages of this training aid contribute significantly to their popularity. They allow for repetitive drills, focusing on batting technique and reaction time, without the potential for serious injury associated with harder projectiles. This characteristic also extends their usability to indoor training environments and confined spaces where standard balls might pose a safety risk. The development of such projectiles reflects a broader trend in sports training towards safer, more accessible practices. This has broadened participation, allowing younger and less experienced individuals to engage in batting practice with reduced apprehension.
