Factors Affecting Swimming Speed


When examining the factors that affect swimming speed, biomechanics plays a crucial role. Biomechanics is the study of the mechanical laws that govern the movements of living organisms. In the context of swimming, biomechanics focuses on the body’s movements and the way they contribute to the overall speed.

There are several aspects of biomechanics that influence swimming speed, including:

  • Body proportions and movements: The body’s proportions and movements play a significant role in determining swimming speed. For instance, a longer torso and limbs can increase the surface area of the body, which can help generate more thrust. However, a shorter torso can provide better balance and stability in the water. The movements of the body, such as the frequency and strength of strokes, also contribute to swimming speed.
  • Muscle power and technique: The muscles used in swimming and the technique employed by the swimmer also affect speed. The core muscles, such as the abdominals and lower back, are essential for generating power and stability in the water. The arms and legs also play a significant role in propelling the body forward. The technique used by the swimmer, such as the catch, pull, push, and recovery of each stroke, can significantly impact the speed.
  • Frequency and strength of strokes: The frequency and strength of strokes also influence swimming speed. A higher stroke rate can increase speed, but it can also lead to fatigue. A lower stroke rate, on the other hand, can provide more power and efficiency, but it may not be as fast. The strength of each stroke is also crucial, as a stronger stroke can generate more thrust.

Overall, biomechanics plays a vital role in determining swimming speed. Understanding the various aspects of biomechanics can help swimmers optimize their technique and improve their speed.

Physiological Factors

When examining the factors that influence human swimming speed, it is crucial to consider the physiological aspects that come into play. These factors contribute to the overall performance of a swimmer and determine the extent to which they can push themselves during a race. The following are some of the most critical physiological factors that affect swimming speed:

  • Aerobic and anaerobic capacity: Aerobic capacity refers to the body’s ability to utilize oxygen to produce energy for sustained physical activity. In contrast, anaerobic capacity is the ability to perform high-intensity exercises without the presence of oxygen. Swimming speed is largely dependent on a combination of both aerobic and anaerobic capacities, as it requires the body to alternate between periods of intense effort and recovery.
  • Muscle composition and endurance: The composition and endurance of a swimmer’s muscles play a significant role in determining their swimming speed. Muscle fibers can be categorized as slow-twitch (Type I) or fast-twitch (Type II) fibers, with the latter being more responsible for short bursts of high-intensity exercise. A swimmer’s muscle composition is influenced by genetics and can be developed through training. Additionally, muscle endurance, which is the ability of the muscles to perform repetitively without fatiguing, is a crucial aspect of swimming performance.
  • Oxygen uptake and delivery: Oxygen is essential for the production of energy within the body’s cells. Swimming requires a constant supply of oxygen to the muscles, and a swimmer’s ability to efficiently absorb and utilize oxygen is critical for maintaining high swimming speeds. Factors that affect oxygen uptake and delivery include cardiovascular fitness, lung capacity, and blood volume. A well-developed cardiovascular system enables the heart to pump blood more efficiently, while a strong respiratory system enhances oxygen exchange. Moreover, an increased blood volume allows for more oxygen to be transported to the muscles.

These physiological factors are interconnected and contribute to the overall swimming performance of an individual. Understanding these factors can help in designing effective training programs that focus on improving swimming speed by targeting the specific areas that need development.

Environmental Factors

When examining the factors that affect human swimming speed, it is essential to consider the environmental conditions in which the swimming takes place. Several environmental factors can impact a swimmer’s speed, including water temperature, viscosity and buoyancy, and currents and waves.

Water Temperature

Water temperature is a critical factor that can affect a swimmer’s speed. The human body’s ability to regulate its core temperature is crucial for maintaining physical activity, and when the water is too cold, it can impair a swimmer’s ability to perform at their best. Cold water can cause a swimmer’s muscles to become stiff and cramped, reducing their ability to move efficiently through the water. In addition, cold water can slow down a swimmer’s metabolism, reducing their energy output and making it more challenging to maintain speed.

Viscosity and Buoyancy

The viscosity of the water can also impact a swimmer’s speed. Viscosity refers to the resistance that the water offers to movement, and it can affect a swimmer’s ability to move through the water efficiently. Highly viscous water can make it more challenging for a swimmer to move their arms and legs, reducing their speed and endurance.

Buoyancy is another factor that can impact a swimmer’s speed. The body’s ability to float or sink in the water can affect a swimmer’s position in the water, and it can impact their ability to move efficiently through the water. A swimmer who is not well-balanced in the water may struggle to maintain speed and may tire more quickly.

Currents and Waves

Currents and waves can also impact a swimmer’s speed. Strong currents can make it more challenging for a swimmer to maintain their position in the water and can impact their ability to move efficiently through the water. Waves can also create resistance and make it more challenging for a swimmer to maintain their speed and direction.

In conclusion, environmental factors such as water temperature, viscosity and buoyancy, and currents and waves can all impact a swimmer’s speed. Understanding these factors and how they can impact a swimmer’s performance is essential for optimizing swimming speed and improving overall performance.

Types of Swimming Strokes

Key takeaway: The factors that affect human swimming speed include biomechanics, physiological factors, and environmental factors. Biomechanics includes body proportions and movements, muscle power and technique, and frequency and strength of strokes. Physiological factors include aerobic and anaerobic capacity, muscle composition and endurance, and oxygen uptake and delivery. Environmental factors include water temperature, viscosity and buoyancy, and currents and waves.



The freestyle stroke is the most common swimming stroke used by both recreational and competitive swimmers. It is also known as the front crawl and is characterized by a combination of arm and leg movements. The speed and technique used in this stroke play a significant role in determining the swimmer’s overall performance.

Arm Movement

In the freestyle stroke, the arms are responsible for propelling the swimmer through the water. The arm movement begins with the shoulders rotating forward, followed by the elbows bending and the forearms moving downward. The hands should enter the water palm-down and sweep back and forth in a windshield wiper motion. The hands should exit the water near the hip, and the arms should recover by rotating the shoulders back and lifting the elbows.

Leg Movement

The leg movement in the freestyle stroke is synchronized with the arm movement. The legs should kick from the hips, and the knees should bend and straighten in a cyclical motion. The feet should point downward, and the toes should curl under the water. The kick should be strong and powerful, and the legs should push against the water to generate thrust.


Breathing is an essential aspect of the freestyle stroke. Swimmers should breathe every two or three strokes, alternating between the left and right sides. Breathing should be done through the mouth, and the head should remain in a neutral position, looking forward.


The freestyle stroke requires proper technique to maximize speed and efficiency. Some key factors that contribute to good technique include body positioning, alignment, and rhythm. Swimmers should maintain a flat back, with the chin tucked to reduce drag. The body should be streamlined, with the legs, hips, and shoulders aligned. The stroke should be repeated with a consistent rhythm, with each stroke following the previous one in a smooth and efficient manner.


The freestyle stroke is beneficial for both fitness and competitive swimming. It provides a full-body workout, engaging the arms, legs, and core muscles. It is also a low-impact exercise, which means it is easy on the joints and can be performed by people of all ages and fitness levels.


The freestyle stroke is the most common swimming stroke and is widely used by both recreational and competitive swimmers. It is characterized by a combination of arm and leg movements, with proper technique playing a significant role in determining the swimmer’s overall performance.

The backstroke is a swimming stroke that is swum on the back. It is one of the four main strokes in competitive swimming, and it is characterized by arm and leg movements that are synchronized.

To perform the backstroke, the swimmer starts by lying on their back and extending their arms forward. The arms are then brought back down and the legs are kicked in a synchronized motion. The hands are then placed back in the water, and the process is repeated.

One of the key requirements for swimming the backstroke is good balance and control. The swimmer must be able to maintain their position on their back and keep their body in a straight line throughout the stroke. This requires a certain level of core strength and stability, as well as good coordination and timing.

The backstroke is a relatively slow stroke, but it is very efficient in terms of energy expenditure. This is because the swimmer is able to take advantage of the buoyancy of the water, which helps to support their body and reduce the amount of effort required to move through the water.

Overall, the backstroke is a technical stroke that requires good control and coordination. While it may not be the fastest stroke, it is an important part of a well-rounded swimming repertoire.


Breaststroke is one of the most popular swimming strokes and is known for its rhythmic arm and leg movements. Here are some key details about breaststroke:

Breaststroke is swum on the chest, with the body lying horizontally in the water. The arm and leg movements are coordinated and require strength and endurance. The arm movements are made by pulling the arms straight back, and then bringing them forward and out to the sides, with the hands close to the surface of the water. The leg movements involve kicking with the feet, first underwater and then above the surface.


Swimmers wear swimsuits made of a fabric that is comfortable and flexible, and that provides a streamlined shape. They also wear goggles to protect their eyes from the chlorine in the pool and to help them see underwater. Some swimmers also wear swim caps to keep their hair out of their face.


To improve their breaststroke, swimmers need to practice the technique, build endurance, and strengthen their muscles. They can do this by swimming laps in the pool, doing drills to focus on specific aspects of the stroke, and doing strength training exercises both in and out of the pool. Swimmers can also work on their starts and turns, which are important parts of the race.


Breaststroke is one of the four competitive swimming strokes in Olympic events. It is often considered the slowest of the four strokes, but it still requires a high level of skill and endurance. In competitions, swimmers start from a diving board or a starting block, and they swim a set distance, usually 50 meters or 100 meters. The winner is the swimmer who completes the distance the fastest.


The butterfly stroke is widely regarded as the most demanding of all swimming strokes. This is because it requires precise coordination between the arm and leg movements, which must be synchronized in a highly specific manner. In addition to this, the butterfly stroke also demands a high degree of strength, technique, and endurance from the swimmer.

One of the key features of the butterfly stroke is the simultaneous movement of the arms and legs. The swimmer must kick their legs simultaneously as they bring their arms forward, creating a “flying” motion that is similar to the movement of a butterfly’s wings. This requires a great deal of coordination and control, as the swimmer must maintain a consistent rhythm and speed throughout the stroke.

Another important aspect of the butterfly stroke is the use of the dolphin kick. This involves the swimmer using their feet to propel themselves through the water, similar to the way a dolphin swims. The dolphin kick is typically used at the beginning of each stroke cycle, and it can significantly increase the swimmer’s speed and momentum.

However, the butterfly stroke is also known for being one of the most technically challenging strokes to master. This is because it requires the swimmer to maintain a specific body position throughout the stroke cycle, with their head positioned forward and their arms and legs moving in a synchronized manner. Mastering this technique requires a great deal of practice and repetition, as well as a strong focus on proper form and mechanics.

Overall, the butterfly stroke is a highly demanding and technically challenging swimming stroke that requires a great deal of strength, technique, and endurance from the swimmer. While it may be difficult to master, the butterfly stroke is also one of the most rewarding and exhilarating strokes to swim, providing a sense of freedom and movement that is hard to match.
