Backstroke (or back crawl) is, as its name implies, the only one of the four competitive swimming strokes swum on the back.
In terms of speed, it is slower than front crawl or butterfly but faster than breaststroke.
The arms execute alternating movements: while one arm sweeps underwater from an overhead position backward to the hips, the other arm recovers above water from the hips to the overhead position, and vice versa.
The legs do a flutter kick: they move upward and downward in alternation, with some flexion at the hips and knees, and with feet pointed.
Swimming Video – Swim Stroke Phases
Below a slow-motion video showing backstroke technique both from above water and from underwater:
The video allows us to have an overview of the different phases of the swim stroke. Let’s consider the following starting position:
1) You float on your back in the water.
2) Your head is in a neutral position, in line with your spine.
3) Your face is above the water surface and you look straight up.
4) Your legs execute a flutter kick. Your toes are pointed and your legs alternately kick upward and then downward.
Your arms execute alternating movements:
5) One arm recovers above water from the hip to the overhead position in a semicircular movement. The arms are kept straight during the recovery.
6) Meanwhile, the other arm sweeps underwater from the overhead position backward to the hip, providing propulsion. The hand follows an S-like pattern during this sweep.
7) The recovering arm becomes the sweeping arm once it enters the water in front of the swimmer, and the sweeping arm becomes the recovering arm when it exits the water at the hip.
The following articles describe the backstroke technique in detail.
Head and Body Positions: This article covers head position, body position and body roll. It also discusses why you may have trouble keeping your legs up.
Arm Movements: This article explains the different phases of the arm stroke, how to create efficient propulsion and how to avoid straining your shoulders.
Backstroke Kick: This article explains how to flutter kick in the backstroke. It also covers kicking rhythms and possible causes of poor propulsion.
Breathing Technique: This backstroke article discusses the relation between balance and breathing. It also talks about breathing rhythms and how to deal with water splashing in the face.
We have a series of swimming drills to learn backstroke step by step. In that series, the following sequence of exercises is used:
1) At first, you’ll practice flutter kicking on your back while holding onto the edge of the pool.
2) Next, you’ll practice balance, floating on your back and sides, using the flutter kick for keeping your balance and moving forward.
3) After this, you’ll practice the underwater and above water arm movements, each arm separately.
4) Finally, you practice doing both arm movements simultaneously.
Elementary Backstroke is another form of backstroke that is easy to learn and ideal for beginners. This article describes the swimming technique of elementary backstroke, and how to learn it.
