Learn the slap shot: a big wind-up, blade into the ice just before the puck, the stick bends and unloads. The hardest shot, step by step and safely.
In the slap shot you wind up wide, put the blade into the ice just behind the puck, press the stick through until it bends, and let it snap forward. The stick acts like a spring that accelerates the puck. It is the hardest shot in ice hockey, but also needs the most time.
The honest answer to "how fast is a slap shot?": in a study with four elite and five recreational players, the elite shooters reached around 120 km/h — about highway speed — the recreational players only around 80 km/h [1]. The puck was on the blade for an average of 38 milliseconds for the elite players, 27 for the recreational ones [1]. Puck acceleration was similar in both groups. So the difference is not in the hardness of the impact but in the timing of the stick: for the elite shooters, the shaft's rebound ("recoil") started only at around 60 percent of the contact time [1].
Two more measurements round out the picture. In a study with 40 people, slap shots were clearly faster than wrist shots — with more vertical force, stronger stick bending and a wider hand position — and puck speed depended on skill and body strength, not on the stick construction [2]. In two professionals, slap shot speed averaged 36.4 m/s, so around 131 km/h [3] — the sample is tiny, but it shows where things can go.
Prerequisites you can check yourself (practical standard, not a study):
The hands grip further apart than in the wrist shot; in the study the hand position was wider in the slap shot, and the skilled players adjusted it further [2]. Milestone: you can guide the stick this way without the blade tipping off the ice.
The slap shot consists of backswing, downswing and follow-through [4]. Hockey Canada splits every shot into preparation, execution and follow-through — and counts forces in the shooting direction, the impact of stick and puck as well as trunk rotation, weight transfer and stick flex as part of the execution [5]. Milestone: you swing through 10 times without a puck and stay balanced.
Put the blade into the ice a few centimeters behind the puck and press the shaft down so it bends. More vertical force and more bending make the slap shot faster [2]. Milestone: you see the shaft bend briefly as you pull through.
The weight runs from the back to the front leg, the trunk rotates through. The hands pull the shaft into the bend, and the stick snaps forward when the puck is on the blade [1]. Milestone: 6 out of 10 strikes hit the puck cleanly; it goes flat into the net or the boards.
The blade swings after the puck and points at the target. Hockey Canada: a good follow-through prevents body segments from slowing down too early [5]. Milestone: you end in a position from which you can move again immediately.
First stationary, then from slow skating, finally from a pass (see One-Timer). A short wind-up ("half slap") is the intermediate stage. Milestone: 5 shots from the blue line in a row that hit the net.
The slap shot is the shot with the greatest risk — for you and for others. You need a helmet with face protection: in an NHL analysis, visors reduced eye and other head injuries but not concussions [6]. Shoot only when nobody is in the radius of your wind-up and in the line of fire, and never at goalies without full equipment. The shooting direction is always toward the net or the boards. Use pucks, never substitute objects. This guide explains and motivates; it does not replace supervised training — the slap shot is safer to learn with a coach.
Play with your hand position. The skilled players in the study generated more vertical force and more stick bend, partly by adjusting their hand position [2]. Shift the bottom hand tentatively a small distance up or down the shaft and notice at which position the shaft swings through best. That is a suggestion, not a rule: which position suits you depends on height and stick.
Hands wide apart, wind up wide, put the blade into the ice just behind the puck, bend the shaft, bring the weight forward and swing through [2]. Practice first without a puck, then stationary at the net, and make sure there is space behind you.
In a study, elite shooters reached around 120 km/h, recreational players around 80 km/h [1]. For two professionals the speed averaged around 131 km/h [3]. For you accuracy comes first, then speed.
The slap shot has a wide wind-up and is clearly faster [2] but needs more time. The snap shot has a short wind-up and is released faster. In traffic and on the move, the snap shot is often the better choice.
Mostly you hit the ice too far behind or in front of the puck, or you swing only with the arms and the shaft does not bend. Use weight and trunk and put the blade a few centimeters behind the puck. According to the study, stick construction hardly decides the speed [2].
