Running is a popular form of exercise, but does it help or hinder muscle growth? The short answer is that it depends on the type of running. High-intensity, short-duration running, such as sprinting or hill workouts, can build muscle mass by increasing muscle protein synthesis (MPS) and tapping into fast-twitch muscle fibers. On the other hand, long-distance running can hinder muscle growth by increasing muscle protein breakdown (MPB) and causing significant muscle damage. Additionally, the nutritional intake, rest, and overall training program of an individual play a significant role in determining the impact of running on their muscle growth.

What You'll Learn
Running builds muscle when paired with resistance training
Running is an excellent form of aerobic exercise that can help strengthen your heart muscle, improve lung function, and increase circulation throughout your body. It is a high-impact activity that can tax your muscles, ligaments, and tendons with each step. While running is a great way to build endurance, it may not be the best way to build muscle mass.
When it comes to building muscle, running has limited effectiveness, especially for those who are consistent runners. However, running can build lower body muscles, particularly in beginner runners. The hamstrings, glutes, quadriceps, and calf muscles are all utilized and strengthened during a run. Faster runs, such as High-Intensity Interval Training (HIIT) workouts, can increase muscle activation and strengthen the legs. Running uphill or downhill can also help build muscle and requires greater core activation for stability.
To build muscle mass effectively, strength or resistance training is essential. This can be achieved through weight training or bodyweight exercises. Resistance training is based on the principle that muscles in the body will work to overcome a resistance force when required to do so. When done repeatedly and consistently, the muscles become stronger. Additionally, resistance training has been shown to have benefits for bone health, reducing the risk of fractures due to osteoporosis.
To maximize muscle growth, it is important to pair running with resistance training and ensure proper nutrition. A robust diet that includes adequate protein, carbohydrates, and healthy fats is integral to supporting the muscle-building process. Without sufficient protein, the body may not be able to build muscle effectively and may even break down existing muscle. Therefore, consuming enough protein is crucial, especially for those engaging in running and resistance training.

Running builds lower body muscles
Running is a great way to build lower-body muscles, particularly in the quadriceps and hamstrings. However, the muscle-building effects of running depend on the intensity and duration of the runs. High-intensity interval training (HIIT) workouts, for example, have been shown to increase muscle activation and strengthen the legs. In one study, participants who performed HIIT workouts three times a week for ten weeks showed an 11% increase in the muscle fibre area of their quadriceps compared to a control group.
The hamstrings, located at the back of the thigh, are essential for force production in the push-off phase of the stride. Strong hamstrings are necessary for improving sprint efficiency and running faster. Running uphill or downhill, or for longer periods, will also require more engagement of the hamstrings and glutes.
Additionally, running is a high-impact activity that stimulates muscle growth by inhibiting proteins that interfere with muscle development and decreasing muscle protein breakdown (MPB). However, long-distance running can increase MPB and hinder muscle growth.
To support muscle growth, it is important to maintain a robust diet with adequate protein, carbs, and fats. Water is also essential, as it helps regulate body temperature and other bodily functions.
While running is an excellent way to build lower-body muscles, it is important to note that the muscle-building effects may plateau over time. To continue building muscle, incorporating strength training and weight-lifting into your routine may be beneficial.

Running builds both slow-twitch and fast-twitch muscle fibres
Running is an excellent aerobic workout that helps strengthen the heart muscle, improve lung function, and increase circulation throughout the body. It is also a high-impact activity that can tax your muscles, ligaments, and tendons with each step.
The proportion of slow-twitch to fast-twitch muscle fibres in a muscle varies depending on its function and the type of training. For example, sprinters benefit from having more fast-twitch fibres, while marathon runners prefer a higher ratio of slow-twitch fibres. However, the concept of ""good" or "bad" muscle fibres is relative, as both types play an important role in everyday life.
Running can build lower body muscles, particularly the leg muscles, and this depends on the intensity and duration of the runs. High-intensity, short-duration running, such as sprinting or HIIT workouts, can effectively build leg muscles, while long-distance running may cause significant muscle damage and hinder muscle growth.
To optimize muscle growth and strength, it is essential to combine running with strength training and a balanced diet rich in protein, carbs, and healthy fats. Additionally, proper footwear and knee support are crucial to preventing injuries and supporting the development of strong leg muscles.

Running builds muscle when paired with a nutritionally balanced diet
Running is an excellent aerobic workout that can help strengthen your heart and improve your lung function. It is a high-impact activity that uses all the muscles in your legs, from big to small, and also gets support from your core, back, and arm muscles.
While running is a great way to strengthen your muscles, it is important to note that it may not be the best way to build muscle mass. This is because running can increase muscle protein breakdown (MPB), especially in long-distance runners, which can lead to muscle loss or inhibited muscle growth. However, this can be mitigated by consuming a nutritionally balanced diet that includes adequate protein, carbs, and good fats.
To build muscle mass through running, focus on shorter duration and higher-intensity workouts such as sprinting or high-intensity interval training (HIIT). These types of workouts stimulate muscle growth by forcing your body to work harder against resistance and demand. Additionally, incorporating elevation changes, such as running uphill, can help build muscle in your glutes, hamstrings, quads, and calves.
It is also important to consider the frequency of your running workouts. Running several times a week will build leg muscle more effectively than running once a week. However, once you start running consistently, you may not see as much muscular growth over time.
Finally, proper nutrition is crucial for building muscle. Consume 0.64–0.91 grams of protein per pound (1.4–2 grams per kg) of body weight daily. This can include meat, poultry, dairy, fish, eggs, soy, beans, and legumes. Additionally, ensure you are staying hydrated by drinking plenty of water before, during, and after your runs.

Running long distances may inhibit muscle growth
Running is an excellent aerobic workout that can help strengthen your heart muscle, improve lung function, and increase circulation throughout your body. It is also a high-impact activity that can tax your muscles, ligaments, and tendons with each step. While running is a great way to improve your overall health, the question of whether it builds or inhibits muscle growth is more complex, and the answer depends on several factors.
Firstly, it is important to consider the type of running performed. High-intensity interval training (HIIT) and sprinting have been shown to increase muscle activation and strengthen the legs. In one study, participants who performed HIIT workouts three times a week for ten weeks showed an 11% increase in the muscle fiber area of their quadriceps compared to a control group. Shorter duration and higher-intensity runs require the body to work harder against resistance and demand, stimulating muscle growth.
On the other hand, long-distance running can significantly increase muscle protein breakdown (MPB) and hinder muscle growth. Research has shown that long-distance runners exhibit higher levels of muscle damage markers, which remain elevated even days after their run. This suggests that while high-intensity, short-duration running builds leg muscles, long-distance running may cause significant muscle damage and inhibit muscle growth.
Additionally, proper nutrition is crucial for muscle growth. Running in a fasted state or with insufficient fuel sources can lead to the breakdown of stored protein in muscle tissues. To support muscle growth, it is essential to consume adequate amounts of protein, carbohydrates, and healthy fats. A well-rounded diet that includes protein sources such as meat, poultry, dairy, fish, eggs, soy, beans, and legumes can help promote muscle growth and repair.
Furthermore, the frequency and duration of running play a role in muscle growth. Someone who runs several times a week is more likely to build leg muscle compared to someone who runs less frequently. However, it is important to note that once an individual starts running consistently, the rate of muscular build may plateau. This is because the body adapts to the demands of consistent running, and muscle growth may slow down as a result.
In conclusion, while running can provide various health benefits, long-distance running may inhibit muscle growth due to increased muscle protein breakdown and muscle damage. To promote muscle growth while running, focus on incorporating high-intensity intervals, ensuring proper nutrition with sufficient protein intake, and varying your running routine to challenge your muscles.
