What is Swimming?
Swimming is a form of water-based activity that involves moving through water using coordinated arm and leg movements. It’s the act of propulsion of the body through the water with the help of the limbs to move in the desired direction. It is typically done in a pool but can also be done in natural bodies of water like lakes, rivers, or oceans. Swimming is used for many purposes, like sports, exercise, and recreation.
Swimming can be a great way to improve cardiovascular fitness, strength, and flexibility. It is also a low-impact activity that is easy on the joints, making it a popular choice for people with injuries or arthritis. Swimming can be enjoyed by people of all ages and skill levels, and there are many different styles and strokes to choose from, including freestyle, breaststroke, backstroke, and butterfly.
Benefits of Swimming
Swimming offers a plethora of benefits regardless of your fitness level. It can potentially strengthen your muscles, elevate your cardio endurance, reverse aging, and calm you down. Even if you think you’re too cool for the pool, the following benefits of swimming may change your mind:
1. Full body workout
Swimming utilizes all the body’s muscles, giving you a comprehensive workout that can even surpass land-based exercise in terms of effort.
2. Enhances overall wellbeing
Swimming thrice a week for 30 minutes, coupled with a healthy, balanced lifestyle, is one of the most effective ways to maintain a fit and healthy body while promoting positive mental health. Swimming with friends is an added bonus of fun!
3. Low-impact exercise
Swimming is a low-impact exercise that is easy on the joints, making it a great option for people with arthritis, injuries, or other conditions that limit their ability to do high-impact exercise.
4. Burns calories
Swimming is a highly effective way to burn calories. A gentle swim for 30 minutes burns over 200 calories, twice the amount of calories burned when walking. Swimming faster burns even more calories than running or cycling. It can be an effective way to burn calories and lose weight.
5. Good for the heart and lungs
Swimming does not just exercise the muscles but also improves lung function and cardiovascular health. Since it involves controlled breathing, lung function, and capacity will be significantly improved. Also, it’s a great aerobic exercise that can strengthen the heart muscles, lower blood pressure, and reduce the risk of heart disease.
6. Reduces stress and promotes relaxation
Whether you’re stressed about work, your kids, or life, swimming regularly can help alleviate stress and depression, reduce anxiety, and promote better sleep patterns. A light swim is enough to experience these mental benefits; there’s no need to pound the lanes.
7. Improves flexibility
Swimming involves a wide range of emotions that can help improve flexibility and range of motion in the joints.
8. Decreases the risk of diseases
Swimming for just 30 minutes a week can reduce the risk of heart disease, stroke, and type 2 diabetes while promoting cardiovascular health.
9. Provides body support
Swimming in water supports up to 90% of the body’s weight, making it ideal for individuals with long-term injuries or illnesses to remain active.
10. Boosts energy levels
Sedentary lifestyles are often responsible for low energy levels. Swimming thrice a week for 30 minutes can elevate your energy levels via increased metabolic rate.
11. Exercise without sweating
If sweating during exercise is a deterrent for you, swimming is an ideal option since the water around you continually cools you down, and you won’t feel sweaty even with intense activity.
History of Swimming
Swimming has a long and rich history that dates back to ancient times. The earliest evidence of swimming dates back to around 4000 BCE, when Stone Age cave drawings were discovered in Egypt that depict people swimming.
In the East, swimming dates back to at least the first century BCE, as there was some evidence of swimming races in Japan. By the 17th century, the teaching of swimming was compulsory at schools due to an imperial edict.
In ancient times, swimming was primarily done for survival, such as crossing rivers or lakes, fishing, or gathering resources from underwater. The Greeks and Romans also saw swimming as an important skill for military purposes and included it in their training programs for soldiers. Swimming was also used for relaxation and recreation, and the ancient Greeks held swimming competitions as part of their Olympic games. The Romans built swimming pools distinct from their baths.
During the Middle Ages, swimming declined in popularity as Europe became more focused on agriculture and land-based activities. According to certain experts, the reason for the absence of swimming in Europe during the Middle Ages can be attributed to the notion that swimming could propagate infections and result in outbreaks. In the late 17th century, swimming was observed at seaside resorts in Great Britain, when people began to view swimming as a way to improve health and fitness. However, swimming wasn’t until the 19th century that it gained significant traction as a recreational and competitive activity.
Swimming became more organized and structured in the 1800s with the formation of swimming clubs and the development of formal swimming competitions. The first recorded swimming competition occurred in 1837 in London, England, and was organized by the National Swimming Society. Also, organized swimming events were held in the 19th century before Japan was opened to the Western world.
During the mid-19th century, two Native American athletes displayed the front crawl at a swimming competition in London, introducing it to the European audience. A few years later, Sir John Arthur Trudgen acquired the hand-over stroke from South American natives, which he introduced in 1873, winning a local competition in England. To date, Trudgen’s stroke is still considered the most powerful stroke to use today.
The introduction of indoor swimming pools in the late 19th century further popularized swimming, as it allowed people to swim year-round regardless of weather conditions.
Captain Matthew Webb was the first individual to swim the English Channel in 1875, using the breaststroke technique, and his accomplishment remained unbeaten for the next 36 years until T.W. Burgess replicated it in 1911.
Other European countries formed swimming federations, such as Germany in 1882, France in 1890, and Hungary in 1896. The initial European amateur swimming competitions were in Vienna in 1889, and the world’s first women’s swimming championship occurred in Scotland in 1892. Swimming also became an Olympic sport in 1896, and since then has been a staple of the Summer Olympics.
In 1908, the Fédération Internationale de Natation (FINA) was established. Australian Richmond Cavill introduced freestyle to the Western world in 1902, and women’s swimming was included in the Olympics in 1912.
Butterfly stroke was created in the 1930s and was initially a modification of breaststroke until it was recognized as a distinct style in 1952.
In December 2022, FINA changed its name to World Aquatics.
Today, swimming is one of the most popular and widely practiced sports in the world, with millions of people participating in competitive and recreational swimming each year.
What is Competitive Swimming?
Competitive swimming is a sport that involves racing against other swimmers to complete a set distance in the shortest amount of time. It is a popular Olympic sport and is practiced worldwide. Competitive swimming events can take place in various distances and styles, including freestyle, breaststroke, backstroke, butterfly, and individual medley. Swimmers compete in lanes; the winner is determined by who touches the finish line first. Competitive swimming requires a high level of physical fitness, technical skill, and mental discipline, as swimmers need to maintain their speed and form over long distances while managing their energy levels.
Competitive swimming gained popularity during the 19th century, aiming to break personal or world records while outperforming competitors in a given event. In order to achieve maximum speed, swimmers aim to create the least resistance while swimming in competition. However, some swimmers who possess excellent technical skills are considered the best even if they don’t hold national or world rankings.
Swimmers typically go through a training cycle that starts with an overloaded workload in the beginning and middle segments of the cycle, followed by a decrease in workload in the final stage leading up to the competition.
Swimming is a featured event at the Summer Olympic Games, where male and female athletes compete in 16 recognized events in a 50-meter-long course pool. Forty officially recognized individual swimming events are in the pool, but the International Olympic Committee only recognizes 32 of them. The World Aquatics, formerly known as the Fédération Internationale de Natation (FINA) until 2023, serves as the international governing body for competitive swimming.
Swimming Strokes and Techniques
Swimming is a versatile sport with various strokes and techniques that swimmers use to move through the water. Each stroke has its unique style, benefits, and challenges, making swimming a fun and challenging sport. Here are the main swimming strokes:
1. Freestyle (Front Crawl)
Freestyle is the fastest and most commonly used stroke in competitive swimming. It involves swimming on the stomach while alternating arm strokes, kicking the legs, and breathing to the side. This stroke requires good upper body strength and endurance, efficient breathing, and a consistent and steady kick.
Freestyle swimming involves diving into the water and then fluttering the legs to return to the surface. The swimmer stretches their body before pushing off and then alternates lifting their hands forward to move ahead. Breathing is only possible when the swimmer’s head is submerged, and upon reaching the end of the pool, the swimmer touches the wall with any part of their body and then somersaults to change direction.
The crawl stroke, used in competitive freestyle swimming, is considered the fastest of all strokes and is preferred for covering long distances. This stroke was first used in the Pacific towards the end of the 19th century and was later popularized by Australian swimmers Henry Wickham and the Cavill brothers in Europe and the United States. The crawl stroke’s arm action was similar to the old sidestroke, while its leg action was a fluttering up-and-down motion performed twice for each arm stroke.
American swimmers later added an extra pair of leg actions, and as many as six kicks were used. In the crawl stroke, the body lies prone, flat on the surface of the water, and the legs are kept slightly under the water. The arms move alternately, with one starting to pull just before the other has finished its pull, ensuring continuous propulsion. To breathe, the swimmer turns their head to either side during the recovery of the arm from that side. Since 1896, the crawl stroke has been used in more races than any other stroke.
The backstroke was first developed in the early 20th century. In this stroke, the swimmer lies on their back, keeping their body as flat and streamlined as possible. They reach their arms above their head and enter the water directly in line with their shoulders, with the palm facing outward and the little finger entering the water first. They pull their arm back to their thigh while slightly rolling their body. The kick was originally a frog kick, but it later involved up-and-down leg movements similar to the crawl.
The backstroke is used in competitive swimming, but it is also a popular choice for recreational swimming as a rest from other strokes, with minimum arm motion and only enough kick to maintain forward motion.
Breaststroke is a slower stroke that requires a frog-like motion. The swimmer’s arms move simultaneously in front of the body, and the legs move together in a whipping motion. Breaststroke requires good flexibility in the hips, knees, and ankles and good timing of the arm and leg movements.
Considered to be the oldest stroke, the breaststroke is commonly used in recreational and lifesaving swimming, as well as in competitive swimming, and is particularly effective in rough water. The stroke involves the swimmer lying face down in the water with their arms remaining underwater. It was originally described in the late 17th century as resembling the movement of a swimming frog. Hence the term “frog kick.” The early breaststroke included a momentary glide at the end of the kick, which was later eliminated in the competitive version. In the old version, breath was taken at the start of the arm stroke, while in the modern breaststroke, breath is taken towards the end of the arm pull.
The butterfly is one of the most challenging swimming strokes and requires great upper-body strength and endurance. It involves a simultaneous arm movement in a circular motion while the legs move together in a dolphin kick. The butterfly is also known for its undulating motion that propels the swimmer through the water.
Unlike the breaststroke, the butterfly stroke is only used in competition and features arms brought forward above the water. Henry Myers first introduced the stroke to U.S. officials in 1933, who claimed that his stroke followed the breaststroke rules. After some controversy, the butterfly stroke was recognized as a distinct competitive stroke in 1953. The original frog kick was replaced with a dolphin kick that relied solely on up-and-down leg movement. Later on, swimmers used two dolphin kicks for every one-arm pull. In sprint competition, breathing is done by raising the head every second or third stroke.
Sidestroke is a versatile stroke that can be used for long-distance swimming, water safety, or leisurely swimming. It involves swimming on the side while alternating arm strokes, kicking the legs, and breathing every few strokes. Sidestroke is known for its efficiency and is often used in military or rescue swimming.
Types of Swimming Events
When it comes to competitive swimming, these are the usual swimming events held:
Swimming competitions consist of various races, including freestyle races at distances ranging from 50 to 1500 meters, backstroke, breaststroke, and butterfly races at 100 and 200 meters, and individual medley races at 200 and 400 meters. Relay races include the freestyle relays, 4×100 meters, and 4×200 meters, as well as the medley relay, 4×100 meters.
Except for backstroke, starts are made from a standing or forward-leaning position to achieve the longest possible glide before the stroke begins. The distance of each race is a multiple of the pool length, making the touch before turning a critical element of success. In relay races, each swimmer touches the starting edge of the pool to complete their leg, allowing the next teammate to dive into the water to begin theirs.
Sprinting in swimming refers to intense swimming for shorter distances. Sprinters put maximum effort into their speed and focus on managing their breathing. They typically compete in races of 50, 100, and 200 meters.
3. Distance Swimming
Distance swimming involves swimming faster and for longer distances. Distance swimmers require high endurance as they swim for extended periods and experience greater strains on their muscles and body. In a race, they strive to maintain a high average speed while trying to relax without significantly reducing their speed. They usually compete in races of 800 or 1500 meters.
4. Middle Distance Swimming
Middle-distance swimming refers to swimming on a longer course than sprinting, but not as long as distance swimming. Middle-distance swimmers do not decrease their speed as rapidly as sprinters when swimming on a longer course and typically have a higher initial speed than distance swimmers. They typically perform their best on tracks ranging from 200 to 400 meters.
The dimensions of a swimming pool for competitive swimming can vary, but the standard size for an Olympic-sized swimming pool is 50 meters (164 feet) in length and 25 meters (82 feet) in width. The minimum depth is 2 meters (6 feet, 7 inches), and the water temperature must be maintained between 25-28 degrees Celsius (77-82.4 degrees Fahrenheit).
For short-course swimming competitions, the pool length is 25 meters (82 feet), and the width is also typically 25 meters (82 feet), with a minimum depth of 1.35 meters (4 feet, 5 inches). However, pool sizes for competitive swimming can vary depending on the specific event or competition.
The outermost lane markers are separated by a distance of 40 cm from the pool walls. In addition, there are center lane markings on the pool’s bottom to assist swimmers in staying in their designated lane. Starting blocks (or backstroke grips) are located on one side of the pool, allowing competitors to dive into the water and swim to the finish line at the opposite end.
Equipment Used for Swimming
You may not need any equipment for recreational swimming, but when swimmers compete, they require some equipment to help them perform at their best. Here are some common equipment used for swimming:
- Swimwear – Swimmers wear special swimsuits that are designed to be light, comfortable, and aerodynamic. Males typically swim bare-chested and wear briefs and jammers, while women wear one-piece suits with thicker and higher backs.
Competitive swimwear aims to enhance speed and coverage beyond what bare skin can provide. In 2009, FINA regulations were revised, and polyurethane suits were prohibited due to their ability to increase buoyancy. Additionally, the rules stipulate that men’s suits cannot go beyond the knee or above the navel, while women’s suits cannot extend past the shoulders or cover the neck.
- Goggles – Goggles protect swimmers’ eyes from chlorine and help them see underwater. They also reduce the glare from the surface of the water, making it easier for swimmers to see the walls and lanes. Prescription goggles may be used by swimmers who wear corrective lenses.
- Swim Caps – Swim caps are worn to keep hair out of the face and prevent drag in the water. They also help keep water out of the ears. These are usually made up of synthetic materials like spandex, lycra, latex, or silicone.
- Kickboards – Kickboards are flotation devices that swimmers hold onto while kicking their legs. They are used to isolate the leg muscles and improve leg strength and technique.
- Pull Buoys – Pull buoys are flotation devices that are held between the legs while swimming. They help swimmers focus on their upper body technique and improve their arm strength. They can also be used as a kickboard that adds resistance.
- Swim fins – Fins are worn on the feet to increase propulsion and speed in the water. They can also be used to improve leg strength and technique.
- Snorkel – Snorkels are used to help swimmers focus on their technique by allowing them to breathe through a tube while keeping their face in the water. They can also be used to improve lung capacity.
- Drag suit – Swimmers wear drag suits during training to intensify resistance, which provides an extra challenge to the swimmer during practice and allows them to feel less resistance while racing. However, drag suits are not permitted for use in competitive races.
In competitive swimming, several officials oversee and manage the competition to ensure that it is conducted fairly and safely. Here are some of the officials and their roles:
- Referee – The referee is the chief official of the competition, responsible for enforcing the rules and making sure that the competition is conducted fairly. The referee also has the authority to disqualify swimmers for rule violations. He or she has full control and authority over all officials.
- Starter – The starter is responsible for starting each race and ensuring that all swimmers start simultaneously. The starter uses a starting system that includes visual and auditory signals to start the race. He or she has full control of the swimmers from when the referee turns them over to them until the race commences.
- Stroke and Turn Judges – Stroke and turn judges are responsible for monitoring the swimmers during the race to ensure that they are swimming within the rules. They observe each swimmer to make sure that they are using the correct stroke and turning at the walls correctly.
- Chief Judge – The chief judge is responsible for overseeing the stroke and turn judges and ensuring they make correct calls. The chief judge also resolves any disputes that may arise during the competition.
- Timer – Timers are responsible for recording each swimmer’s time in each race. They use electronic timing systems and backup manual timing systems to ensure accuracy. A chief timekeeper assigns the seating positions of all the timekeepers and the lanes for which they are responsible.
- Clerk of Course – The clerk of the course, also called the bullpen, is responsible for organizing the swimmers before each race and ensuring that they are in the correct lane and heat. They also manage the distribution of race results and awards.
