Strength training for volleyball: the jump and the spiking shoulder

You jump a hundred times in a session, hit as many balls, and what hurts afterwards is never the thing you trained. It is the front of the knee and the shoulder. Volleyball lives at two extremes, a maximal jump and a maximal arm swing, and strength work is the only tool that keeps you intact at both ends for a full season.

What the sport actually does to you

A player racks up dozens of jumps in a match, and a middle blocker or opposite can pass a hundred once training is counted. Every jump also has a landing, and the landing is the part the body pays for: the knee, the Achilles tendon and the hips absorb forces several times body weight, on a hard floor.

Then there is the shoulder. In a spike the upper arm rotates back close to the end of its range, then whips forward in a couple of hundredths of a second. The back of the shoulder and the muscles around the shoulder blade act as the brake, and that is where problems usually show up in players who compete several times a week.

So the gym has two jobs: add height to the jump, and build a shoulder that tolerates thousands of swings without flaring up.

The jump: strength first, speed after

Jump height comes down to how much force you can produce and how fast you can produce it. Recreational and younger players usually gain most from plain strength, because their base is small. Experienced players who already squat a decent load tend to improve faster through rate of force development and a cleaner approach.

The backbone is a full-range squat: 3 to 4 sets of 4-6 reps, with a load that leaves you one or two reps in reserve. If you are starting out, do not chase the number on the bar, because the squat has a sensible learning order that is worth respecting before load goes up.

Add single-leg work: Bulgarian split squats, lunges, step-ups, 3 sets of 6-8 per leg. A volleyball take-off is almost never symmetrical, and single-leg training narrows the gap between sides. For the hamstrings, use Romanian deadlifts or Nordic curls, 3 sets of 6-8.

Plyometrics is its own block, not a finisher. Box jumps, drop landings and repeated vertical jumps are done fresh, 3-5 sets of 3-5 reps, with a full minute or two between sets. Sixty to a hundred foot contacts a week is plenty to begin with, and never on a day you have already hit two sessions of spikes.

The shoulder: the brake matters more than the engine

Power in the swing comes from the legs, hips and trunk. The shoulder is the last link, and its main job is to slow the arm down after contact. That is why shoulder training for volleyball is not bench press. It is rotator cuff, scapula and a lot of pulling.

• External rotation with a band or cable, 3 sets of 12-15 per arm, with a deliberately slow return of about three seconds.
• Scapular work: press-up plus, Y and T raises on an incline bench, face pulls, 2-3 sets of 10-15. Archers train the same pattern, because shoulder blade control decides everything for them too.
• Pulling: rows and pull-ups, at least as many sets as you do pressing. A one-to-one ratio is the minimum, and two-to-one in favour of pulling suits anyone hitting overhead every day.

Long-serving players often lose internal rotation on the hitting arm, so that hand reaches behind the back less easily than the other one. Gentle cross-body stretching and thoracic spine mobility help, but the evidence that stretching alone prevents injury is not strong. Strength through the back of the shoulder plus a sane weekly count of swings is the more reliable pair.

The swing belongs to the same movement family as throwing, so the principles from baseball training carry over well: the shoulder is protected when the rotation starts at the hips and trunk rather than at the arm.

Landing and the knee

Pain just below the kneecap is the most common long-running complaint in volleyball. It builds from the sum of landings, sharp stops and a hard court, and can rarely be traced to one moment.

Two things help most. The first is landing technique: land on both feet, let the hips and knees absorb the force, and do not let the knees collapse inwards. The second is loading the tendon, because tendons respond to gradual work rather than rest: slow decline squats, half-squat holds of 30-45 seconds, and heavy slow lifting twice a week.

If the knee already hurts when you squat, do not simply drop the exercise. Knee pain in the squat usually calls for a change in depth, load or tempo, and far less often for stopping altogether.

Fitting it into the week

Out of season, three strength sessions a week is a realistic ceiling: two built around the legs and the jump, one around the upper body and shoulder. Cuff and scapular work goes into all three, since the volume is small and it takes minutes.

In season, two sessions of 35 to 45 minutes hold on to what you built. Put them straight after a ball session or on a day without a match, and keep heavy leg work at least 48 hours away from a game.

Progression stays simple: each week add a rep or 2.5 kilos while the technique holds, then when it stalls, drop the load by around ten per cent and climb again. Coming back after a long layoff, give the first three weeks to volume and technique rather than load; the six-week return plan applies here too.

When the jump starts dropping and heavy legs last for days, that is a sign the total load is too high, not that you are training too little. The signs of overtraining show up first in jump height and in the shoulder.

When to see a doctor

See a doctor if shoulder pain travels down the arm, if you get numbness or weakness lifting the arm, or if you cannot swing without a sharp catch. The same goes for a knee that swells, locks or gives way on landing.

Pain lasting more than three or four weeks despite reduced volume also deserves a look. With tendons, going early shortens the recovery, and waiting stretches it into months.

The short version

• Jump height is built with full-range squats, 3-4 sets of 4-6, plus single-leg work and plyometrics done fresh.
• Protect the shoulder with external rotation, scapular work and at least as many pulling sets as pressing sets.
• The knee needs landing technique and gradual tendon loading, not rest.
• Three strength sessions a week out of season, two shorter ones in season, and no heavy legs within 48 hours of a match.
• A falling vertical jump is the earliest warning that total load has gone too high.
