In Four Competitive stroke Breaststroke was the first and Backstroke was the third stroke to gain recognition in Olympic in 1908 for men. It took another 16 years before women’s event was included in 1924.
History of Four Competitive stroke are given below:-
Crawl/freestyle is one of the Four Competitive stroke. Crawl or freestyle is the fastest stroke in water. The following alternative movements – arm pull and quick leg-beat-place a swimmer in a propulsive position all the time. This stroke is about four seconds faster than the next fastest stroke, butterfly.

Like all other strokes, front crawl has undergone many far-reaching changes after World War 2. Flat elbow recovery was replaced with higher elbow recovery. This mode of recovery has less resistance, according to analysts.
While a swimmer competing in sprint events has to climb virtually over water to propel fast, it is not necessary that middle-distance competitor should hold the head so high. High head, it is said, bring greater resistance at the shoulders and requires greater leg power to overcome it. The general position of the feet is that heels and rear part of the toes just break the surface of the water on the up-kick and drive to the position of about 45cm underneath.
For sprint events, experts recommend six leg beats in one cycle arm pull. But for middle distance races, it is not necessary that six leg beats may be used. For long distance races, swimmers even use only two leg beats. Whatever some leg beats, the emphasis is that movement should be systematic so that there is as little resistance as possible. The lesser the resistance, the greater will be the propulsion of the body. It should be left to an individual to decide his variation to suit his individual style of swimming. For arms stroke, the need is off pull, push and recovery. If these three areas are coordinated properly, the leg-beat provides all the thrust for the body to move ahead.
In front-crawl, adequate control of breathing is essential. It requires a thorough training because taking too much air, or too little is detrimental to speed.
Backstroke was the third stroke to gain recognition in Olympic in 1908 for men. It took another 16 years before women’s event was included in 1924.
William call was the first to win the backstroke event in 1903 when the ASA staged the championship. Then double arm swims with inverted breaststroke leg movement was in vogue by leading swimmers.
Soon the technique underwent sea-change in this stroke. First alternate leg action was introduced and then alternate arms movement. These change made the stroke fast and impressive to watch.
There have been changes in the stroke to make it faster, but flutter kick remains the cornerstone for this stroke which some call it as ‘back-crawl’.
Breaststroke became an Olympic event in 1904. It was because freestyle, called crawl, had already become much faster stroke.
The technique of the breaststroke was that the swimmer would lie on his breast with the hands projected directly out in front of the face and hands pulled wide and round.
The breaststroke underwent change when some swimmers in 1930 took advantage of laxity of rules in digging into the water with a double overhead arm stroke; some swimmers started using butterfly arms with traditional breaststroke leg movement. Occasionally, they even used Dolphin kick. This experiment started in 1935. The Dolphin kick was indeed useful for speed, but it was exhausting. Many swimmers choose to traditional breaststroke leg movement.
Butterfly stroke is unquestionably the most exacting of four strokes. In Four Competitive stroke It requires tremendous strength and stamina. This explains why many swimmers, proficient in the 100 meters, are unable to maintain their rhythm and cardiac, vascular endurance in the 200m.
Butterflyers come in all sizes, shapes and weights. There are many among them swimming 75m with perfect stroke using Dolphin kick. But they battle hard in the concluding 25m. The worse is the situation for those who are competing in the 200m event. This is because their stamina and strength are not in enough measure to sustain them the entire course of the distance.
