It’s arguable that nothing is more daunting in team sports than men teeing up powerful volleyball spikes. Some pros can get a "kill" down at 80 mph. There is a vast difference, however, between the average speed of a man’s volleyball spike at the Olympic level and those at lower levels.
The average speed of a volleyball spike from men is most impressive at the Olympic beach or indoor level. Bulgaria’s Matey Kaziyski, for example, recorded a spike that reached 132 km/h, which is equivalent to 80.8 mph, in an international volleyball match in 2012. The average speed of an Olympic volleyball spike from men is roughly 70 to 80 mph. The velocity is highest at this level since the attackers have the necessary mechanics to pummel the ball.
The men's game at the college level doesn't draw the same attention as that other indoor sport, basketball, but it's still a showcase for guys who can throw it down. The average speed of a man’s spike in NCAA competition is charted in the 50 to 60 mph range.
High School Level
The post impact speed of a volleyball spike depends on specific, scientific factors, like the trajectory of a player’s upward movement and the force behind his arm action. Most high school guys don't have that kind of skill set yet, which is why the average kill is in the 40 to 50 mph range.
Science and Speed
A player’s ability to effectively time and execute a strike plays a major role in the spike's speed. The degree, or body angle, a player is at when his hand connects with the ball ultimately effects its velocity. It's something the best players eventually learn since it usually translates into an effective offense. A team that can constantly attack with fast spikes can frustrate blocks and keep a defense on its heels.
