The scientific analysis of a 170 km/h fastball

His 170 km/h fastball is one of the most dominant plays in baseball.

By accurately measuring the ball’s speed, understanding the physical characteristics of the ball, and analyzing the pitching form and mechanics, we can gain a deeper understanding of the true essence of a fastball.

Here we take a detailed look at the scientific analysis of a 170 km/h fastball.



How to measure speed

Advanced technology is required to accurately measure a 170 km/h fastball.

Here are the main ways to measure it:

Radar guns : Radar guns are the most common way to measure pitching velocity. They measure the velocity of the ball from the moment it is released until it reaches the catcher’s mitt. This data is very reliable because it shows the velocity closest to the pitcher’s release point.

Trackman System : Trackman is a system that uses radar technology to measure the ball’s trajectory and spin rate. This allows you to analyze not only the speed of the ball, but also the rotation and trajectory of the ball. Trackman is widely used at professional level.

High-speed cameras : Using high-speed cameras, we can capture detailed footage of the ball from release to catch, and calculate the speed for each frame. This method is very useful for analysing the ball’s trajectory and minute movements at the release point.



Ball physics

To understand a 170 km/h fastball, the physics of the ball are also important.

Air resistance : When a fastball is thrown, the ball experiences air resistance. Air resistance reduces the ball’s speed, so it is important to minimize it. The surface condition and rotation speed of the fastball greatly affect air resistance.

Spin and Gyroscopic Effect : The spin rate of the ball greatly affects its stability and trajectory during flight. A high spin rate creates the effect of the ball appearing to rise, making it harder for the batter to time the ball. This effect, also known as the gyroscopic effect, increases the power of a fastball.

Ball Material : The material of the ball also affects its speed. Major League Baseball and Nippon Professional Baseball use slightly different materials, which can affect the flight characteristics of the ball. For example, the height and stiffness of the seams on the ball affect the pitcher’s grip and release of the ball.



Pitching form and mechanics

To throw a 170 km/h fastball, you need to have the correct pitching form and understand mechanics.

Power transmission : When pitching, it is important to transmit power from the lower body to the upper body. It starts with stepping on the ball, and the power is transmitted to the arm through the torso. By performing this series of movements efficiently, you can generate maximum speed.

Release Point : Fastball velocity is also affected by the release point. A good release point will apply optimal force to the ball and maximize velocity. A consistent release point will also improve control.

Shoulder and Elbow Action : Accurate shoulder and elbow action is also important. These joints are subjected to the greatest forces when throwing a fastball, so they need to move at the proper angles and timing. Proper training and form modification are essential to reducing the risk of injury and maintaining fastball velocity.


The true nature of a 170 km/h fastball can be revealed through scientific analysis.

By better understanding how velocity is measured, the physics of the ball, and pitching form and mechanics, it is possible to maximize the devastating power of a fastball.
