Learn the dig: low stance, steady platform, cushioning the ball, reading early. With milestones, mistake list, rules check and an honest look at the evidence.
How do I defend hard attack balls without the ball flying away? The honest answer: with the forearm pass from a low defensive stance, a steady platform and a ball you cushion rather than hit. The dig is not a new stroke but a forearm pass under time pressure. The teaching material of the West German Volleyball Association counts field defence standing and while falling as separate defensive techniques [2].
There are hardly any scientific studies on the technique of the dig itself. So we rely on association material about the forearm pass [1][2] and on research about reading game situations [3]. Anything we mark as practice standard carries no [n].
Place your feet wider than shoulder width, bend your knees, bring your weight forward and hold your hands in front of the body. Move like a very agile boxer, as the teaching material puts it for the ready position [1]. In defence you go a bit lower than in normal passing (practice). Milestone: hold for 30 seconds without wobbling.
Form the platform while the ball is still flying towards you. If you bring your arms together only at the ball, you are late. The teaching material stresses: build tension in the forearms before playing the ball [1]. Milestone: the platform is set before the ball passes the net tape.
On hard balls the ball comes at you with a lot of energy. Then you do not need to accelerate it further. Play with a small arm movement and a measured leg extension and give a little with the ball (practice). The teaching material uses this image: "The ball is like a raw egg that must not burst on contact with the platform" [1]. Milestone: 8 of 10 bounces or short throws land in a target zone under control.
The ball does not always come at your body. Go in front of the ball when you have time, and practise the volleyball-typical movement forms (crossover step, side steps) for it [1]; with time pressure use a lunge to get to arm's length (practice). The angle of your platform determines where the ball goes: turn the platform slightly towards the target instead of swinging the arms. Milestone: 6 of 10 balls from changing directions into the target.
Whoever reads early needs less reach. In an experiment experienced players predicted the direction of a setter's toss faster and more accurately than novices, with fewer but longer fixations [3]. For you that means: do not spread your gaze everywhere but collect the important information (setter, ball, attacker) on purpose. An error in reading can also come from perception; the teaching material names poor dynamic visual acuity as one cause of problems in the forearm pass [1]. Milestone: before the attack you call out where the ball is probably going, and you are right in 5 of 10 cases.
In defence you are close to the floor and close to teammates. In an analysis of 16 years of injury data in US collegiate women's volleyball, one in five game injuries came from floor contact, and equally often from landing on another player (21 percent each) [4]. Ankle sprains were the most common injury there (44.1 percent of game injuries) [4]. Call the ball ("Mine!") and look around so you do not collide with teammates (practice).
This guide explains and motivates; it does not replace supervised training.
Use the rule in your favour. On your team's first contact the ball may touch several body parts in succession as long as it is one action [5]. A ball that bounces from your forearm to your hand or upper arm is therefore not a double fault in defence. Catching and throwing remain forbidden [5]. So you can go to the ball relaxed and do not have to pretend that you must hit it perfectly with the platform.
They are not required, but in defence they can protect the skin on the hall floor from scrapes. They replace neither technique nor warm-up. If you dig a lot and often hit the floor, they are a sensible small item (practice).
On flat, fast or far-away balls you use the forearm pass. Through rule changes the overhead set is increasingly used in defence as well, according to the teaching material [2]. Decide by the flight path: high and slow often works with a set, hard and low needs the forearm pass.
On your team's first contact, yes, as long as the touches happen in one action [5]. That also applies when the ball comes over the net after an attack. On the second and third contact it would be a double contact.
Only partly. You can train positioning and the low ready position alone. For bounces and hard balls you need a partner or a wall. At the wall, watch distance and free space (practice).
