Swimming & Scuba Diving Statistics 2021

Interested in the latest 2021 stats, data and fun facts on swimming and diving?

I’ve painstakingly put this list together as a die-hard fan of all things swimming and scuba diving. This data is correct as of September 2021, and will continue to be updated as I find more and more information to add to it!


General Swimming Facts

  • A study found that swimmers lose weight and body fat not just because of the amount of time they spend in the pool but also due to the sheer amount of energy they expend.
  • Swimming burns around 600 calories per hour compared to 400-500 for running, cycling or rowing.
  • Swimming has even been shown to help with appetite control as it can suppress levels of ghrelin – a hormone which stimulates hunger – by up to 68 percent after one hour.
  • Swimmers were able to hold their breath twice as long shortly before swimming events than during them indicating they are better at managing oxygen shortages before the competition. 10 percent for short distances and 25 percent for long distances
  • Swimming is great for your heart health as it is a medium-intensity aerobic exercise.
  • Swimming improves your cardiovascular fitness and blood circulation, strengthening the heart muscle so it can pump more blood with each beat.
  • Swimming can be an effective natural pain reliever as water pressure reduces inflammation making it useful for those who suffer from chronic conditions such as arthritis.


Interesting Swimming Statistics

  • On average, pro swimmers can swim the equivalent of 22 miles per day.
  • One swimming pool contains enough water to fill 10 million glasses of water.
  • The Swimming Teachers Association has over 200 members worldwide.
  • 100 percent of elite male and female open-water swimmers shave their legs before swimming long distances in open waters for speed purposes.
  • Swimming is one of the seven sports recommended by health experts as part of a healthy lifestyle alongside cycling, football, jogging, running, playing tennis and walking.


How many people go swimming as a hobby?

  • Swimming is the most popular hobby in Great Britain with 6.2 million people swimming at least once a week. In the USA, it is practiced by around 123 million people.
  • Swimmers compete in many different types of races but the most popular are the 50-meter long front crawl and butterfly stroke.
  • The world’s largest swimming event is held each year in Setubal, Portugal and attracts over 600,000 participants who swim across beaches and coves.
  • Swimming has been shown to increase the brain power of children as it stimulates growth in areas which control memory, understanding and awareness. Swimmers can also process information faster after learning a new skill. Swimming helps with social development through friendship groups formed both in and out of lessons by helping self esteem, confidence and independence.
  • Swimming helps capture happiness by providing opportunities for outdoor play that releases endorphins making them feel happy while boosting their immune systems through Vitamin D production from regular sunlight exposure helping prevent illnesses. Swimmers also spend less time feeling stressed as water is an awesome stress reliever allowing lower blood pressure and heart rate meaning swimmers


Diving and Scuba Diving Statistics & Facts

  • The first scuba diving regulator was invented in 1952 by two Frenchmen, Maxime Forjot and Jean de Wouters d’Oplinter.
  • Although scubas are made of high grade metal or plastic, several parts of the scuba set can deteriorate over time. For instance, rubber hoses will eventually erode due to exposure to sun light, oxygen and chemical reactions with chlorine which is present in salt water that has seeped into the airways.
  • Although scuba diving and scubas may look like a relatively new invention, scuba gear has actually been in existence since 1850.
  • Around 70 percent of scuba divers prefer to dive alone while the remaining 30 percent prefer to buddy up. Diving with friends is considered more fun compared to diving solo because there is less responsibility should something happen underwater (like an emergency) and this also allows scuba divers to spend less time on dives since they won’t be spending as much time looking for their buddies. Another reason why scuba divers prefer diving solo is because they get tired of waiting for their buddies who might be slow and thus take more time than planned and affect the amount of bottom time (time spent underneath water).
  • Scuba divers should aim for a minimum of 100 dives before they can call themselves an experienced scuba diver. This however does not mean that scubas shouldn’t scuba dive with inexperienced scubas since there is no such thing as an “experienced scuba.” Even the most skilled and experienced scuba divers such as cave divers and technical scuba divers train newbies in their respective disciplines. A person is only considered an “open water diver” if he or she has completed the basic training which includes learning how to use all types of equipment (regulator, buoyancy control device, mask, fins, scuba diving suit, etc.) and how to respond when in an emergency situation.
  • Although scuba divers can stay underwater for about 40 minutes on average, some scientists estimate that scubas could actually swim down as deep as 1,000 fsw (feet scuba diving) and stay there for as long as 80 minutes. However, scubas’ lungs would need to be conditioned which means that scuba divers who scuba dive 300 feet beneath the water’s surface should scuba dive around 3 times a week for at least 8 weeks.
  • Men who scuba dive can limit their weight of equipment (regulator, scuba tank, etc.) to no more than 40 pounds or 18 kilograms while women are required to limit theirs some what between 35 pounds or 16 kilograms and 45 pounds or 20 kilograms.
  • One out of every five scuba divers die due to drowning since most scubas tend to panic whenever they encounter some sort of emergency underwater. Other causes of death among scuba divers include scuba diving accidents, scuba diving related medical conditions and scuba diving related equipment failures.
  • The minimum age for scubas to be allowed to scuba dive is usually 10 years old unless there are restrictions placed by the country’s laws or by the country’s governing body for managing scuba diving affairs. However, an individual can probably scuba dive at 9 years old if his or her parents take full responsibility for him or her while he or she is underwater.
  • There are 2.59 million scuba divers actively participating in the sport in the USA alone (2020 Data)
  • A frequent scuba diver is classed as someone who goes on over 15+ dives per year
  • In 2017 there were an estimated 6.5 million scuba divers, free divers and snorkelers worldwide
