10 Differences Between Swimming In A Pool And Swimming In Open Water

Swimming is a popular form of exercise enjoyed by millions worldwide. Whether you prefer the controlled environment of a pool or the thrill of open water, each setting offers unique experiences and challenges.

Understanding what is the difference between swimming in a pool and swimming in open water can help you make the most of your swimming journey.

1. Water Temperature

The water temperature is one of the most significant differences between pool and open-water swimming. Indoor pools are typically heated to a comfortable range, usually between 25-28°C (77-82°F).

This consistent temperature allows swimmers to focus on their training without worrying about the effects of cold water. In contrast, open water temperatures vary greatly depending on the location and time of year.

Even in summer, lakes, rivers, and oceans may feel much colder than a heated pool. Swimmers must be prepared to handle the shock of entering cold water and the potential effects on their bodies and performance.

 

2. Visibility

Pool swimming offers excellent visibility, with swimmers able to see the bottom and follow lane lines. This helps swimmers maintain their orientation and navigate the pool efficiently. On the other hand, open water can present challenges regarding visibility.

Depending on the water conditions, swimmers may have limited or no visibility of the bottom or surroundings. This can lead to disorientation and the need for frequent sightings to stay on course.

 

3. Safety

Pool swimming is generally considered safer than open-water swimming. Pools are controlled environments with lifeguards on duty and easy access to the sides or bottom if needed.

Open water swimming, however, carries inherent risks such as changing weather conditions, strong currents, and potential hazards like wildlife or hidden obstacles. Swimmers must be prepared to handle these challenges and always prioritise safety.

 

4. Mental Preparation

The mental demands of pool and open-water swimming differ significantly. Pool swimmers often focus on achieving specific times or competitive placements with the knowledge that they can complete their races.

Open water swimmers, however, must also contend with the possibility of not finishing a swim due to conditions or unexpected challenges. This uncertainty can lead to increased anxiety and the need for strong mental resilience.

 

5. Physical Preparation

Training for pool and open-water swimming requires different approaches. Pool training often emphasises speed and technique, with swimmers focusing on specific distances and intervals.

Open water training, on the other hand, tends to prioritise endurance and adaptability. Swimmers may consistently cover longer distances while practising skills like sighting and navigating in varied conditions.

 

6. Environmental Factors

Open-water swimming is influenced by external factors such as waves, currents, and weather conditions. These elements can affect a swimmer’s pace, technique, and overall experience.

Pools provide a stable and controlled environment, allowing swimmers to focus on their training without the interference of external forces.

 

7. Technique And Stroke Adaptation

While the basic swimming strokes remain the same in both settings, open-water swimming often requires adaptations to technique.

Swimmers may need to adjust their breathing patterns, stroke length, and body positioning to accommodate waves, currents, and sighting. Pool swimming allows for more consistent technique without these adjustments.

 

8. Motivation And Goals

The reasons for choosing pool or open-water swimming can vary. Pool swimmers may be motivated by the desire to improve their times, win competitions, or achieve specific goals within the sport.

On the other hand, open-water swimmers may be drawn to the adventure, personal challenge, and connection with nature that open-water swimming offers. Both settings provide opportunities for personal growth and fulfilment.

 

9. Equipment Use

Pool swimming allows for the use of various training aids, such as kickboards, pull buoys, and paddles. These tools can help swimmers focus on specific aspects of their technique and build strength.

Open-water swimming, however, often limits the use of such equipment due to practical considerations and safety concerns. Swimmers may rely more on wetsuits for warmth and buoyancy, especially in colder waters.

 

10. Performance

A study published in the Scandinavian Journal of Medicine & Science in Sports compared performance, kinematic, and physiological variables between elite triathletes swimming in open water and a 25-metre pool. The research involved 14 elite triathletes who completed 1500-metre swims in both conditions.

Swimmers exhibited lower stroke length (SL) and stroke index (SI) but higher stroke rate (SR) in open water compared to pool conditions. This suggests that swimmers may adopt a different technique to adapt to the less predictable environment of open water.

There are no significant differences in physiological responses, such as heart rate, blood lactate concentrations, or oxygen uptake, between the two conditions. However, the respiratory exchange ratio was lower in open water, indicating a different metabolic response to swimming in these environments.

 

Tips For Transitioning From Pool Swimming To Open Water Swimming

Transitioning from pool to open-water swimming can be an exciting but challenging experience. Here are some tips to help you navigate the process:

  • Start gradually: Begin by swimming in calmer, controlled open water environments like lakes or protected bays before venturing into more challenging conditions.
  • Seek guidance: Consider joining a local open-water swimming group or working with an experienced coach who can provide guidance and support as you adapt to the new setting.
  • Practice sighting: Incorporate sighting drills into your training to improve your ability to navigate and maintain your course in open water.
  • Invest in proper equipment: Ensure you have a well-fitting wetsuit (if needed) and other essential gear, such as a tow float or safety buoy, to enhance your comfort and safety.
  • Prioritise safety: Always swim with a partner or in a group, be aware of your surroundings and potential hazards, and follow local guidelines and regulations for open water swimming.

Frequently Asked Questions About Open Water Vs Pool Swimming

Is Open-Water Swimming Better Than Pool Swimming?

The answer depends on personal preference and goals. Open-water swimming offers a unique experience with nature. It can enhance mental well-being, while pool swimming provides a controlled environment that is often safer and more predictable for training.

Is Open Water Swimming Harder Than Pool Swimming?

Open-water swimming can be more challenging due to factors like water temperature, visibility, and the need for navigation. However, it is not necessarily “harder,” just different, as each environment presents its own set of challenges and benefits.

Does Open-Water Swimming Burn More Calories Than Pool Swimming?

Yes. Open-water swimming typically burns more calories because the body works harder to maintain temperature in colder water and to navigate waves and currents.

How Do I Find Safe Open-Water Swimming Locations?

Research local beaches, lakes, or rivers that are designated for swimming. Look for areas with lifeguards, swimming events, or local swim clubs that can guide safe spots. Always check water quality reports and heed any warnings.

Can I Swim In Open Water If I’m A Beginner?

Absolutely! Many beginners start with open-water swimming. It’s important to take a gradual approach: begin in calm, shallow waters, wear a wetsuit for buoyancy, and consider taking lessons to build confidence and skills before venturing into more challenging conditions.
