Swimming Backstroke in a Straight Line: Three Orientation Techniques

Backstroke is the only competitive swimming stroke performed face-up, which presents a unique challenge—you cannot directly see where you are going. Yet elite swimmers still manage to swim perfectly straight lines in a 50-meter pool. How do they do it?

1. Common Causes of Veering in Backstroke

• Imbalanced pulling strength between the left and right arms
• Asymmetrical kicking
• Head movement caused by breathing (backstroke still requires controlled breathing rhythm)
• Uneven body rotation on both sides

2. Three Key Orientation Techniques

Technique 1: Ceiling Landmark Method (Indoor Pools)

Most competition pool ceilings have fixed structures (beams, lights, strips) that can serve as visual references:

• Within the first 10 meters after starting, lock onto a fixed object directly overhead
• Keep your body’s central axis aligned toward that object
• Check your direction every 5 strokes

Note: Looking up at the ceiling will cause your lower body to sink. Your gaze should shift using only your eyes, not by turning your head.

Technique 2: Lane Line Awareness

Lane lines are the backstroke swimmer’s “direction sensors”:

• Use peripheral vision to sense the position of the lane lines on both sides
• If one lane line gets closer, it means your body is drifting toward that side
• Make immediate micro-adjustments to pulling force or leg direction

Advanced: Experienced swimmers can gauge how many centimeters they have drifted by feeling where their fingers touch the lane line.

Technique 3: Using the Backstroke Flags

Backstroke flags (a row of plastic pennant flags) are placed 5 meters from each wall. They are essential tools for backstroke swimmers to judge the distance to the wall:

• Start counting strokes after passing the flags
• Each swimmer should memorize “how many strokes it takes from the flags to the wall”
• Male swimmers: approximately 5–7 strokes
• Female swimmers: approximately 6–8 strokes
• The final stroke should be fully extended—never shortened midway

3. Body Position and Swimming Straight

The foundation of swimming backstroke in a straight line is body position:

4. Pulling Trajectory

There are two mainstream pulling trajectories in backstroke:

Straight-Arm Pull

• After the hand enters the water, pull straight from the shoulder line back to the thigh
• Simpler, suitable for beginners
• Lower propulsion efficiency

Bent-Arm Pull (EVF Version)

• After the hand enters the water, the elbow drops and the forearm is perpendicular to the water surface
• The pulling path resembles an “S shape”
• High propulsion efficiency; the mainstream choice among elite swimmers

5. Turn Judgment

Backstroke turns use the flip turn (permitted since the 1991 rule change):

1. Count strokes after passing the backstroke flags
2. Flip onto the stomach after the final stroke
3. Push off the wall with both feet after completing the flip
4. Roll back onto the back after pushing off
5. Perform underwater dolphin kicks (within 15 meters)

6. Training Drills

Drill 1: Eyes-Closed Straight Swimming

• Spot a ceiling landmark before starting
• Swim 10 strokes with eyes closed
• Open your eyes and check whether you have drifted

Drill 2: Single-Arm Backstroke

• Keep one arm against your side while the other arm pulls
• Trains pulling strength balance on each side
• 25 meters on each side

Drill 3: 6-1-6 Drill

• 6 kicks (rotating to one side) + 1 stroke + 6 kicks (rotating to the other side)
• Trains coordination between body rotation and swimming straight

7. Quantitative Metrics

• 50m stroke count: Men 24–28 strokes, Women 28–32 strokes
• SWOLF: Men 35–40, Women 38–43
• Lateral deviation: After swimming 50m, your body should still be in the center of the same lane

Conclusion

Swimming backstroke in a straight line is not just about visual judgment—it is a comprehensive combination of strength balance, rhythm control, and muscular sensation. It is recommended to include at least one “eyes-closed backstroke” session per week to strengthen non-visual directional awareness.
