Learn the head-first jump from the pool edge: small stages from kneeling to standing, with clear rules on water depth, evidence-based risks and stop criteria.
The head-first jump from the pool edge is called "Sprung kopfwärts" in the German examination rules: you enter deep water hands first, body tight, at a shallow angle. The honest answer to "Do I have to be able to do this?": yes, if you want the German swimming badge. In the DLRG examination regulations (2025 edition), every practical exam in Bronze, Silver and Gold begins with a head-first jump from the pool edge, and "safe swimming" requires that you master the tuck jump and the head-first jump [1].
The second honest answer: no other beginner jump can cost you as much if the depth is wrong. In a Hamburg case series of 160 patients with tetraplegia after a head-first dive into shallow water, the mean age was 24, the paralysis was complete in two thirds, and the average hospital stay lasted 202 days – about six and a half months [3]. In Miami, shallow-water dives were associated with spinal-cord injuries of the lower cervical spine requiring surgery [4].
So learn the head-first jump in stages, supervised, in a pool whose depth you know. Be realistic: until it sits tight and flat, you usually need several sessions (rule of thumb, not a study value).
See the bottom, read the depth marking and have the lifeguard confirm the jumping zone. There is no single "safe" number: a review cites minimum depths for diving between 1 and 1.52 metres and notes that 89 percent of injuries occurred in water shallower than 1.52 metres [2]. Competition pools with starting blocks require at least 1.35 metres between one and six metres out from the wall [5] – for experts who have mastered the dive. As a learner you want considerably more.
Kneel at the edge, toes curled over, arms stretched overhead, head between your upper arms. Tip forward and glide in flat – like a knife, not like a stone. The principle from the swimming teaching manual: arms fully stretched, they "enclose" the head, the whole body stays tight [6]. Milestone: five consecutive flat entries without a belly flop.
Go into a crouch, hands on the edge, eyes on the target spot in the water. You push forward and out of your feet. The "small start jump" from a crouch is about a wide, flat arc and as long a glide as possible [6]. According to the review, standing dives by untrained jumpers need a larger safety margin than kneeling or crouching dives [2] – hence the order. Milestone: after the crouch you glide in flat and steer your hands upward after entry.
Stand at the edge, toes gripping it, arms overhead. Tip forward, push off and tighten your body before you touch the water. No run-up, no jump upward. Milestone: you fulfil the exam requirement "clear take-off and complete immersion" [1] three times cleanly.
After entering, turn your hands upward and steer to the surface. Steering upward and protecting the head with the arms are among the recommendations of injury research [2]. Practise this deliberately on every repetition.
Plan the steering before the take-off. Talk to yourself: target spot, body tension, hands up. The question "How deep is it here?" belongs before the jump, not after – and that is not caution, it is technique. A safe head-first jump is a planned head-first jump.
Yes. According to the DLRG examination regulations (2025 edition), the practical exam for Silver begins with a head-first jump from the pool edge; this also applies to Bronze and Gold [1]. Older regulations or club documents may differ – ask your examiner.
There is no uniform figure. Reviews cite minimum depths between 1 and 1.52 metres [2], competition pools require 1.35 metres at starting blocks [5]. Examination rules require deep water [1]. For you: jump only in designated zones of known depth.
With the wrong depth, yes: jumps into shallow water cause severe cervical spine injuries [3][4]. With known depth, a tight body and practised technique the risk falls, but does not disappear [2].
No. The jump from the pool edge must go into deep water [1], and almost nine out of ten injuries occurred in water shallower than 1.52 metres [2].
