Swimming has been a fundamental skill for humans, evolving from a means of survival to a structured sport. The history of swimming strokes dates back thousands of years, with early techniques used for crossing waters and military training.
Over time, these strokes were refined into distinct styles, leading to the four competitive strokes we know today: freestyle, backstroke, breaststroke, and butterfly.
This article explores how swimming strokes developed through history, their role in different cultures, and their transformation into modern competitive techniques.
Early Evidence Of Swimming
Swimming has been an integral part of human life for thousands of years, with evidence suggesting that early humans developed basic swimming techniques for both survival and cultural purposes.
Ancient civilisations such as the Egyptians, Greeks, and Romans documented swimming through murals, sculptures, and texts, highlighting its significance in their societies. Over time, swimming evolved from a fundamental life skill to a structured activity, influencing the techniques seen in modern swimming today.
Swimming In Ancient Civilisations
One of the earliest depictions of swimming dates back to 10,000 BC, with cave paintings found in the Cave of Swimmers in the Gilf Kebir region of Egypt.
These illustrations show human figures performing strokes that resemble the breaststroke and dog paddle, suggesting that swimming was already a recognised skill at the time.
Additionally, Egyptian tomb paintings from 2000 BC feature swimmers using coordinated arm and leg movements, further confirming that swimming was both practised and appreciated in ancient societies.
The Greeks and Romans also valued swimming, incorporating it into their daily lives. In ancient Greece, swimming was considered an essential skill, often taught alongside running and wrestling as part of military and athletic training.
The Greek historian Plato even remarked that an uneducated man was someone who “cannot read or swim,” reinforcing the idea that swimming was a fundamental ability. Public baths and pools were common in Greek and Roman societies, where people gathered for recreation, hygiene, and exercise.
Roman soldiers were trained to swim across rivers using breaststroke-like movements, demonstrating its importance in military strategies. The Romans even built man-made swimming pools for training purposes, some of which were large enough to host early forms of competitive swimming.
Swimming As A Survival Skill
Before swimming became a sport, it was primarily a survival skill. Early humans relied on natural bodies of water for hunting, gathering, and migration, requiring them to develop techniques to move efficiently in the water.
Rivers and lakes served as primary sources of food, and being able to swim allowed early humans to catch fish, collect aquatic plants, and travel more effectively. Tribes living near coastal areas or rivers naturally integrated swimming into their daily routines, ensuring that future generations inherited this vital skill.
Migration also played a key role in shaping swimming techniques. As humans expanded across continents, crossing rivers and lakes became a necessity for survival. Those who could swim had an advantage, as they could navigate water barriers while carrying supplies or even assisting non-swimmers.
In some cases, rudimentary rafts were used alongside swimming techniques to transport goods and people. The sidestroke and basic flutter kick were likely developed during these early crossings, allowing for controlled movement in strong currents.
Trade further contributed to the refinement of swimming skills. Civilisations that engaged in maritime trade and fishing needed to ensure their survival in case of shipwrecks or accidents.
Historical accounts describe Phoenician and Viking sailors who were highly skilled swimmers, capable of navigating rough waters and saving fellow crew members. These practical uses of swimming laid the foundation for more structured techniques that were later refined for competitive and recreational purposes.
Development Of Specific Strokes
Swimming strokes have evolved significantly over the centuries, from basic survival techniques to refined movements used in competitive sports. Early swimmers relied on simple strokes such as the breaststroke and sidestroke, which prioritised energy conservation and stability.
Each stroke developed in response to the need for better speed, endurance, and technique, shaping modern swimming as it is practised today.
Breaststroke
Breaststroke is one of the oldest recorded swimming strokes, with origins tracing back thousands of years. Ancient Egyptian, Greek, and Roman depictions of swimming often show figures using a movement that closely resembles breaststroke.
Early versions of this stroke involved simultaneous arm movements and a frog-like kick, making it a practical choice for swimming in calm waters. Unlike strokes designed for speed, early breaststroke prioritised control and endurance, making it a popular technique for long-distance swimming.
In the 17th century, breaststroke was one of the first strokes to be documented in a book. In 1696, French writer Melchisédech Thévenot described it in The Art of Swimming, further solidifying its place as a recognised technique.
By the time competitive swimming emerged in the 19th century, breaststroke had already been established as a preferred stroke due to its stability and accessibility for swimmers of all levels.
Although breaststroke remained largely unchanged for centuries, competitive swimming introduced refinements to improve its speed and efficiency.
Early competitive swimmers used a head-above-water technique, which caused significant resistance and slowed movement. Over time, swimmers discovered that keeping the body streamlined and closer to the surface reduced drag, allowing for smoother strokes.
By the 1930s, new techniques emerged, including the underwater pullout and dolphin kick, which increased speed and momentum. However, these variations were later regulated to ensure fair competition.
Modern breaststroke now features a coordinated arm pull, powerful kick, and a glide phase, maximising efficiency while conserving energy. Competitive swimmers also focus on explosive starts and turns, using underwater techniques to gain an advantage.
Sidestroke And The Trudgen
Sidestroke was historically favoured for its efficiency and ease of breathing, making it a preferred stroke for survival and long-distance swimming.
Unlike strokes that require a rhythmic breathing technique, sidestroke allows swimmers to keep their heads above water at all times, providing a clear line of sight while swimming. This made it particularly useful for lifesaving, military training, and endurance swimming.
One of the key features of sidestroke is its scissor kick, where the legs move in a split motion before coming together for propulsion.
The top arm pulls while the bottom arm extends forward, creating a smooth and energy-efficient stroke. This technique enabled swimmers to cover long distances without exhausting themselves, making it an essential skill for soldiers, lifeguards, and rescue personnel.
Sidestroke was widely taught in military training programmes, especially in the 19th and early 20th centuries. Soldiers and sailors used this stroke to navigate rivers, assist wounded comrades, and perform water rescues.
Although sidestroke is no longer used in competitive swimming, it remains a valuable skill for water safety and survival training.
In the late 19th century, British swimmer John Trudgen introduced a new variation of sidestroke that incorporated an overarm stroke.
During a visit to South America, he observed indigenous swimmers using a technique that involved alternating arm movements rather than the traditional sidestroke’s sculling motion. By adapting this style, Trudgen created what became known as the Trudgen stroke.
This new stroke was faster and more powerful than the original sidestroke, as the overarm motion reduced drag and increased propulsion.
Trudgen’s technique quickly gained popularity in competitive swimming, where swimmers sought any advantage to improve their times. The stroke eventually evolved into front crawl, which became the dominant stroke for freestyle swimming.
Front Crawl (Freestyle)
The front crawl, known today as freestyle, has its origins in Indigenous swimming techniques. European swimmers initially used strokes like the sidestroke and breaststroke, which were slower but allowed for greater stability.
However, in the 19th century, British swimmer John Trudgen observed Indigenous South American swimmers using a fast overarm stroke with a scissor kick. This technique was far more efficient, as it allowed for continuous propulsion with minimal resistance.
Trudgen introduced this stroke to Europe, where it was later refined by Australian swimmers, who replaced the scissor kick with a flutter kick, further improving speed and efficiency.
The adoption of the front crawl revolutionised competitive swimming, particularly in freestyle events. By the early 20th century, it became the dominant stroke in races, as it proved to be much faster than the sidestroke and breaststroke. In the 1920s and 1930s, swimmers refined the technique further by focusing on bilateral breathing and improved body rotation, which helped reduce drag and maintain momentum.
The front crawl became the foundation of the freestyle category, where competitors could choose their preferred stroke. Its introduction significantly reduced race times, making it the preferred technique in international competitions, including the Olympic Games.
Backstroke
Backstroke was originally developed as a variation of breaststroke, allowing swimmers to move efficiently while keeping their faces out of the water.
Early swimmers discovered that by flipping onto their backs and performing a similar arm and leg motion to breaststroke, they could reduce fatigue while maintaining a steady pace. This method was particularly useful for open-water swimming, where visibility and breathing were crucial.
Unlike breaststroke, which required frequent head movements for breathing, backstroke allowed for uninterrupted respiration, making it a practical alternative for long-distance swimming.
By the early 20th century, backstroke became a recognised competitive stroke, with swimmers modifying the original technique to increase speed and reduce resistance. Instead of using a frog kick, competitors adopted a flutter kick, similar to that of the front crawl, which provided better propulsion.
The arm movements also evolved from a simple sculling motion to a continuous overarm stroke, allowing for smoother and faster swimming. When backstroke was included in the Olympic Games in 1900, its rules became more structured, leading to the development of the modern technique used today.
Over the years, advancements in training methods and technology have greatly improved backstroke performance. High-speed cameras and underwater analysis have helped refine body positioning, stroke efficiency, and turn techniques.
The introduction of the backstroke flip turn in the 1990s allowed swimmers to maintain momentum during turns, cutting down race times significantly. Additionally, modern swimsuits designed for hydrodynamics reduce drag, helping swimmers move through the water with greater ease.
Today, backstroke is a key event in competitive swimming, with athletes continuously pushing the limits through strength training, technique optimisation, and scientific research.
Butterfly Stroke
The butterfly stroke originated as an alternative technique to breaststroke in the 1930s, when swimmers experimented with new ways to increase speed. Traditionally, breaststroke required both arms to move in a circular motion underwater.
Some swimmers discovered that by bringing their arms out of the water in a simultaneous motion, they could reduce drag and swim faster.
This modification initially remained within the breaststroke category, but as the technique continued to evolve, it became clear that it was fundamentally different from traditional breaststroke.
The key difference was the introduction of the dolphin kick, where both legs move together in a wave-like motion instead of the traditional frog kick used in breaststroke. This change significantly increased speed, making butterfly the second-fastest stroke after freestyle.
By the time butterfly debuted as an independent event in the 1956 Olympics, swimmers had already refined the technique, incorporating powerful upper body strength, precise timing, and streamlined turns.
Butterfly is widely regarded as the most physically demanding stroke, requiring exceptional strength, coordination, and endurance.
The simultaneous arm recovery motion and dolphin kick create intense resistance, meaning swimmers must generate maximum propulsion with each stroke while maintaining rhythm.
Unlike freestyle and backstroke, where one arm moves at a time, butterfly requires full-body engagement, making fatigue set in much quicker.
Competitive butterfly swimmers must train rigorously to build upper body strength, core stability, and cardiovascular endurance to sustain the stroke for race distances ranging from 50m sprints to 200m events.
