Creating the world's first unthetered punching bag was no easy task. The challenge was maximizing control by finding the optimum combination of weight, speed, and density.
Balancing these components was like a puzzle we had to solve -- a difficult proposition because adjusting one parameter dramatically affects the other two. Eventually, we found what we call the OODA Ball's "Goldilocks zone”.
Weight. The ball cannot be too light or too heavy. Too light and it's like punching air, but go too heavy and you'll hurt yourself. Let's remember that the ball is not on a standstill. There is serious kinetic energy involved when you have to hit a moving object coming at you, and then send it in the exact opposite direction. Here we have the equation force equals mass times velocity to deal with.
Density. The ball cannot be too soft or too hard. Too soft is not good because it does not offer enough resistance and does not represent the normal density of a typical target of a punch -- like a human body. Too hard makes it too difficult to control as it reduces the amount of surface contact between the ball and the fist, not to mention the increased risk of injury. Unlike conventional designs (speed bag and heavy bag), the OODA Ball is often hit at unpredictable angles. A harder ball also makes it susceptible to unexpected trajectories due to wall imperfections.
Velocity. The ball cannot be too slow nor too fast. Too slow and you will not have enough bounce to be at a convenient distance from the wall. Gravity is at play here. The ball is in constant fight against gravity and therefore requires a minimum speed to overcome it. Too fast would just be too difficult to hit.
The quest for optimum control starts with the core.
The OODA Ball's Coefficient Of Restitution is mostly defined on this layer... and that's all we can disclose.
The coefficient of restitution (COR) is the ratio of the final to initial relative speed of two objects after they collide. It typically ranges from 0 to 1, with 1 representing a perfectly elastic collision.
Introducing OODA Ball: a compact, portable punching ball designed to be both functional and interactive. We were so confident in the final product that we figured it could lead the charge with it's, own bag and matching gel wraps.
We first invented the OODA Ball because there existed no fight-fitness training tool on the market that simulated the movement, mixed striking, and feel of an MMA fight.
