Terrestrial locomotion is carried out by various organisms for food, shelter, protection, in search of potential mates, escape from danger, or fulfilling other necessities.

The locomotion on land can be broadly divided into two types based on speed and energy expenditure. They are – walk or run.
Walk vs Run
The main difference between walk and run is that walk is a type of natural terrestrial locomotion that does not have any serious impact on the joints while run is a type of pounding exercise and can cause inflammation of anchors, knees, and even the hips.
In walking, the number of calories burned is comparatively less. So the amount of energy required to walk is also comparatively lower.
The process of walking is also known as an inverted pendulum gait. The pace and speed of walking are usually slower but they can be increased also.
Depending upon the speed and the energy expenditure, walking can be divided into various types.
On the other hand, in running The number of calories burned are comparatively more. So the amount of energy required to walk is higher.
The process can explode the muscle which adds to the performance of fast and slow twitching of the muscle fibers. The oxygen requirement of a runner is higher than the process of walking.
Comparison Table Between Walk and Run
|Parameters of Comparison||Walk||Run|
|Definition||It is a process where at least one foot is in contact with the ground throughout||It is a process where both the feet are off the ground|
|Velocity||The angular and linear velocity of lower limbs in walking is slower||The angular and linear velocity of lower limbs in running is faster|
|Intensity||Involves lower intensity||Involves higher intensity|
|Type of movement||Natural movement from one point to another||Faster movement from one point to another|
What is Walk?
Walk or the process of walking is a type of terrestrial locomotion found in legged organisms.
The process of walking is also known as an inverted pendulum gait, which implies that the body vaults over limbs or stiff limbs with every step.
Ancestors of modern humans had been walking similarly to present walking which is evident from the footprints discovered on the shore of Kenya which are about 3 million years ago.
The derivation of the word walk is from an old English term called “wealcan” which means to roll. Apart from the normal type of walking, walking can be of several other variants.
It can also refer to snowshoeing, scrambling, trekking or cross-country skiing, beach walking, and nordic walking. Walk which is done at a faster pace is known as speed walking.
Walking at a speed of around 7 to 9 kilometers per hour from the natural range of walking gait is known as power walking.
Walking is also related to various other athletic events like pedestrianism, race walking, and other forms of a walk.
A rhythmic breathing technique that is usually synchronized during the process of walking is known as Afghan walking which was mainly discovered in the 1980s.
The process of human walking is done by the double pendulum. This process has a forward motion in which the leg leaves the ground and swings forward.
The first sweep is known as the first pendulum. The next leg hits the ground with the heel first rolls to the store and is known as an inverted pendulum.
What is Run?
Run or the process of running is a type of terrestrial locomotion. The process can be characterized by its aerial phase. The process includes all the feets that are above the ground.
The pace and speed of running are faster than other types of gait. The running process has proven to improve health and expectancy of life in various forms.
During running, the changes in kinetic as well as potential energy occur simultaneously within the stride.
Depending upon the speed of running, it can refer to different varieties of running like sprinting, jogging, and others.
Historically, the ancestors of humankind had to run over long distances to hunt animals and gather food.
Running is also considered the most accessible sport in the world. In various parts of the world, the origin of competitive running was from religious festivals.
The evolution of running in humankind is considered to be at least four and a half million years ago from the apelike ancestors.
The process of running can be classified into two main phases.
They are stance and swing and are divided in regard to the lower extremity. It can be further classified into initial swing, absorption, terminal swing, and propulsion.
The beginning of the running cycle is marked with absorption and footstrike. For running the idle posture of the runner is slightly tilted forward and should be upright throughout.
Main Differences Between Walk and Run
- Walking has a longer stance phase while running has a double swing phase.
- The swing phase in walking is shorter while the swing phase in running is longer.
- Walking is a slower process while running is a faster process.
- The range of motions required in walking is less while the range of motion required in running is greater.
- Walking is a relaxed process and the muscles do not get tired easily while running is a pounding exercise and the muscles get tired soon.
Most of the legged organisms show two types of terrestrial locomotion that are walking or running. Both types of movement have different features.
In humankind, the practice of both types of movements has been for a very long time to fulfill various needs and requirements. Both the movement processes engage a different type of movement of the foot.
In humans, both types of movements require specific postures. In walking the back should be lengthened head should be kept high and the arms are usually swung while running the body is slightly tilted forward and kept upright throughout the process.
Both the processes have distinct features in regards to swing phase, speed, time, the area covered, and other related parameters.
