What muscles are used when you run?



Presse Santé

Although running is a full-body exercise, it primarily uses your core and lower body muscles. It is important that these key muscles remain strong and healthy as they are responsible for the stability, shape and alignment of your spine, all of which allow you to perform at your best with maximum efficiency.
Understanding how each muscle works can help you improve your running form, technique, and performance. Keeping these muscles balanced and working together in harmony will also help you prevent injury.

In this article, we take a closer look at the muscles used when running.

trunk muscles

A strong and stable core is the foundation for a healthy body and for most movements and activities. Located in the torso and pelvis, the core muscles connect the upper body to the lower body.
A strong core helps maintain good posture, balance, and form while running. It can also help to properly align your spine, pelvis, and lower body. Strong abs help keep your body straight and reduce the impact of blows to the back. A weak core can cause you to compensate with other muscles, which can lead to injury.

hip flexors

The hip flexors are located in the front of the hips, just above the thighs. They connect the femur to the lower back, hips, and groin. The hip flexors help stabilize the pelvis and spine. During running, you use these muscles when you bend your knee and leg toward your body, as well as when you swing your legs forward. To ensure mobility, it is important to maintain the strength and flexibility of the hip flexor muscles. A contraction of the hip flexors can compromise the action of the gluteal muscles, which can lead to compensation in other areas, or even injury.

The gluteal muscles are located in the buttocks. The strength of these muscles plays a vital role in running as they propel you forward and help you run faster. The glutes also help keep your torso stable so you can maintain good posture. As the primary muscles responsible for hip extension, they also help stabilize and strengthen your hips. This helps keep your spine, knees, and feet in alignment.


The quadriceps are a group of four long muscles located in the front of the thigh. As you run, they extend your knee and propel you forward. The energy that starts in the quadriceps is transferred to the hamstrings. Connected to the kneecap, the quadriceps are responsible for straightening and stabilizing your knees when you run.


The hamstrings are located at the back of the thigh, between the hips and the knees. They are responsible for hip extension and knee flexion. The hamstrings also contribute to the extension of the thighs as you move the upper leg back. You engage your hamstrings to lift off the ground with each step and maintain knee flexion, which helps prevent hyperextension. Bending your knees to bring your feet up toward your buttocks helps propel you forward. To maintain peak efficiency as a runner, you must have strong and flexible hamstrings. Otherwise, your form suffers and your risk of pain and injury increases. Many people have weak hamstrings in relation to the quads, which can lead to overcompensation and imbalances in the hips, knees, and overall stride.

calf muscles

The calf muscles are located at the back of the lower leg. You use these muscles every time you push and lift your leg to propel yourself forward. The calf muscles are also involved in extension and flexion of the foot each time the foot strikes and pushes back. They are responsible for reducing the impact of the impact when landing, balance and mobility of the ankle.

Running uphill or downhill: which muscles work more?

Running uphill or downhill requires slightly different form because you’re working your muscles differently. As you run from side to side, make sure to align your torso with your pelvis.

downhill race

Downhill running is easier on the heart muscles. But the muscles in the hips, legs, and ankles need more work, especially the hip extensors, quads, and knees. Going downhill, you risk putting too much pressure on your shins, which can lead to shin splints. You naturally use the heel of your foot more, which helps slow your forward motion. Be careful not to lean your upper body too far back.

Mountain’s race

When you run uphill, you have to work harder and activate more leg muscles to overcome gravity. Compared to running on a flat surface, you engage the vast quadriceps muscles more and the hamstrings less. Running uphill requires switching to a midfoot or forefoot strike. This type of impact puts more pressure on your calves and ankles, but also makes it easier to get off the ground. This is because some of the impact energy is absorbed by your calves, giving you power as you go.

When running uphill, focus on using your hip muscles to propel yourself forward and fully extend your leg behind you. Avoid leaning too far forward when running uphill, as this can make it more difficult to engage your hip flexors to lift your knee. Running uphill can negatively affect your balance and drive.

Does running also work the tendons and ligaments?

Running also exercises the tendons and ligaments, which help absorb some of the shock. Tendons are connective tissues that connect bones to muscles, contributing to smooth movement and shock absorption. Ligaments are connective tissues that connect bones to each other. By absorbing some of the stress and shock of running, they help keep the body stable and prevent too much movement between the bones.

Importance of running muscle warm-ups

According to most doctors, you should warm up before you start exercising for at least 5 minutes before moving on to stretching. Strenuous exercise like running can shorten and tighten muscles, which can reduce mobility and limit range of motion. It is important to keep your muscles loose, flexible, and supple to avoid aches, pains, and injuries.

Key points to remember

It’s important to understand the main muscles you use when running, as well as the mechanics of the movements. If you add a stretching and strength training routine that targets key running muscles to your exercise routine, your muscles will work together to help you run optimally and efficiently.

Biological diversity, that beneficial treasure for our health



Presse Santé

Life began in the sea. The earth’s surface is made up primarily of oceans, which are home to the oldest and most diverse forms of life. Thus, the marine environment is the treasure of biological and chemical diversity among all types of ecosystems. There is a wide variety of living organisms, from bacteria to eukaryotes, as well as unique chemical compounds that are of great importance to medicine, nutrition, cosmetics, agriculture and other industries.

The benefits of algae:

The vitamins, minerals, and all the other good natural chemicals found in seaweed have many health benefits for humans, without the huge side effects that medications can have.

Seaweed oils have long been known to aid recovery from illness by detoxifying the body and promoting the renewal of damaged skin cells.

Seaweed contains carotenoids and polyphenols that have been shown to be powerful antioxidants. Antioxidants help the body fight oxygen free radicals that damage cells and cause aging and disease.

The iodine present in seaweed is essential for the thyroid gland to regulate the body’s metabolism.

Seaweed has been used as an effective external treatment for conditions such as psoriasis, eczema, dermatitis, and acne.

In short, algae can be used for internal and external body treatments. The nice thing is that it’s pure goodness, minus the nasty elements and no animals that suffered in lab tests.

Seaweeds have multiple uses: you can eat them dry (in salads and hot dishes), or take them as a dietary supplement in the form of capsules, or use them in cosmetic products such as creams, shampoos, after-shampoos, soaps, massages. oils…

The benefits of sea lettuce:


Sea lettuce, along with other sea vegetables, is very popular in Okinawa, Japan. The Okinawa Centennial Study found that Okinawans are 82% less likely than the average American to suffer from coronary heart disease. She attributed this longevity in part to the consumption of these mineral-rich sea vegetables.

Liver Health:

Sea lettuce contains natural photosynthetic pigments that give it its beautiful green color. It has a high concentration of a-chlorophyll, b-chlorophyll, xanthophylls, lutein, beta and gamma carotene, siphonxanthin and siphonin.

Chlorophyll is capable of preserving healthy cells and tissues in our body by strengthening phase II biotransformation enzymes. These encourage optimal liver health and thus the natural removal of potentially harmful toxins from the body.

eye health:

Sea lettuce is extremely rich in vitamin A in the form of beta-carotene and gamma-carotene, compounds that have been shown to significantly reduce the risk of cataracts and macular degeneration.

One of the first symptoms of a deficiency of this important vitamin is “night blindness” or nyctalopia. In addition, vitamin A maintains the integrity of the cells of the mucous membranes, including those of the eyes.

Sea lettuce also contains lutein, which is known to be good for eye health by reducing free radical damage to eye cells.

Marine worm’s oxygen-saving technology could preserve organs before transplants

A French biotech company has discovered and developed a product that is currently being tested for use in human transplants. The product, dubbed “Hemo to Life,” is created from a sea worm, scientifically known as Arenicola marina. This organism, about 450 million years old, can survive several hours without oxygen under ocean sand. Scientists have identified in the worm a special hemoglobin molecule capable of stabilizing oxygen 40 times more than human hemoglobin. The company seeks to use this feature to deliver more oxygen to transplanted organs during surgery.
