Learn the jump topspin serve in volleyball: spin toss, approach, take-off behind the end line and topspin hit. With build-up, rules, mistakes and shoulder care.
Is the jump serve really the best serve? The honest answer: It is the hardest, but not automatically the most effective. At a men's Olympic qualification tournament, 84.9 percent of the 377 measured serves were jump serves. Their speed averaged about 23 metres per second, around 83 kilometres per hour, country-road speed for a car. Float serves reached only about 12 metres per second. Even so, the authors found no relationship between serve speed and effect [6]. Only 25.3 percent of jump serves could be received so that a first-tempo attack became possible [6].
That is the honest number behind the spectacle: a jump serve pays off when it comes in controlled, not when it just comes in hard.
The toss is the base. You toss the ball forward and up with one hand and the ball gets rotation. The rules allow exactly one toss; the ball may be moved or dribbled in the hands, but you must not toss it repeatedly [1]. Milestone: 10 tosses in a row land in a target circle of about one metre in front of the end line.
Now you hit the ball with topspin from standing after the toss. The ball is hit with one hand or any part of the arm [1]. The hand rolls over the top of the ball. Milestone: 8 of 10 balls land in the opponent's court.
Now with take-off. The take-off point must be behind the end line; at the moment of the hit or the take-off the server must not touch the court or the floor outside the service zone. After the hit you may land in the court [1]. Milestone: 7 of 10 serves from the two-step succeed without your foot touching the line.
Now the three-step approach and the arm swing are added. What matters is what happens between take-off and hit. In a study of 17 male professionals, the speed of the hitting hand was related to the forward tilt of the pelvis and the hip flexion of the non-hitting leg [4]. That means: your pelvis tilts forward briefly and the free leg pulls along. A second study from the same group found that arm swing speed was related to the angular momentum of the hitting arm, non-hitting arm and hand. Balance and controlled force from elbow and wrist play a role [2]. Milestone: 6 of 10 serves with a full approach land in the court.
Diagonal and straight require different body rotation. In a study of jump serves hit straight and diagonal, hand speed was higher in the diagonal version, 17.0 versus 16.4 metres per second, which is about 61 versus 59 kilometres per hour of hand speed. Pelvis and upper torso were also rotated further forward [3]. Choose your target from the opponent's reception, not from ego. What made life hard for the opponent is shown by World Cup data: the tennis jump serve, deep serves and receptions near the end line or sideline forced the setter more often into an unacceptable setting zone [7]. Milestone: in 10 serves you hit the agreed zone 6 times.
The jump serve loads the shoulder. In a lab study with 14 collegiate women, forces and torques were clearly higher in hard hits than in the float serve. The jump serve data (only five players, not analysed) were similar to those of hard spikes [5]. The authors recommend reducing repetitions and limiting jump serves when you have symptoms [5]. A review names shoulder overuse as one of the three big injury topics in volleyball, alongside ankle and patellar tendon [8]. The build-up principle: toss first, then standing, then two-step, then full approach. This guide explains and motivates, it does not replace supervised training or a coach.
Count your jump serves in training. Beginners tend to do too many. Instead of 50 hard serves in a row: 3 sets of 10, with breaks and float serves in between for relief. The lab study on shoulder load recommends limiting the number of jump serves when you have symptoms [5]. That is an inference, not a dose-response recommendation.
You must be behind the end line at the moment of take-off: neither the court nor the floor outside the service zone may be touched. After the hit you may land in the court [1].
Eight seconds after the first referee's whistle [1].
No. In an analysis of 377 serves there was no relationship between serve speed and effect [6]. Targeted placement is more important.
It loads it heavily. The data of a lab study with only five players are similar to those of hard spikes [5]. With warm-up and dosing you can manage the load.
