Running long distances can lead to muscle loss, but it is not the act of running itself that causes this. Muscle loss is caused by a calorie deficit, which can be created by running. If you are running a lot, you need to increase your food intake to match the calories burned. Additionally, if you are running so much that you are unable to do strength training, you will lose muscle mass because running does not work those muscles enough or in the right way. However, it is possible to run and maintain or even build muscle mass. Resistance and strength training can help with this, as can adequate nutrition and protein intake.
| Characteristics | Values |
|---|---|

What You'll Learn
Running long distances can chip away at muscles if not mindful of calories
Running long distances can chip away at muscles if you are not mindful of your calorie intake. Running is an aerobic exercise that is a great tool to burn calories. Due to this caloric expenditure, running is often associated with the loss of body fat as well as muscle mass.
The body can only store a maximum of about 2000 calories in glycogen stores. When glycogen is depleted, the body has to burn a different fuel to create more ATP (cellular energy) for the working muscles. This is when the body starts to burn muscle protein for fuel. Therefore, when you’re in a glycogen-depleted state, running burns more muscle mass.
However, this muscle loss can be prevented with proper nutrition and training strategies. It is important to ensure that your calorie intake matches the number of calories burned while running. Running long distances without increasing your food intake accordingly can lead to a calorie deficit that can halt or even reverse muscle development.
Additionally, incorporating strength training and adequate protein intake into your routine can help mitigate muscle loss while running. Resistance training and weight training can help to maintain or even increase muscle mass. It is important to note that running itself does not consume muscles, and the myth that running "eats up" muscles is largely based on the observation that elite distance runners tend to have lower body fat and leaner muscles.

Running doesn't directly consume muscles, but it can be a factor
Running is an excellent form of exercise that provides numerous health benefits. However, there is a prevalent misconception that it directly consumes muscles, leading to their shrinkage. This belief likely stems from the observation that elite distance runners often exhibit a lean physique with minimal muscle mass. While running by itself does not directly consume muscles, it can be a contributing factor in muscle loss under certain conditions.
Firstly, running can be a factor in muscle loss if it replaces strength training in your fitness routine. Muscles require stimulation and resistance to maintain their mass. If you prioritise running over strength training, your muscles may not be sufficiently challenged, leading to a decrease in muscle mass over time. Therefore, it is essential to incorporate strength training into your routine to maintain and grow your muscles.
Secondly, running can contribute to muscle loss if it creates a significant calorie deficit without a corresponding increase in food intake. When you expend more calories than you consume, your body enters a catabolic state, breaking down muscle tissue for energy. This is particularly true for long-distance running, which can deplete your body's glycogen stores, forcing it to burn muscle protein for fuel. Therefore, ensuring adequate calorie and protein intake is crucial to prevent muscle loss while running.
Additionally, running can cause muscle loss if it is not complemented by proper nutrition and training strategies. Resistance training, such as weightlifting or bodyweight exercises, can help counter the catabolic effects of long-distance running by stimulating muscle growth and repair. Including a variety of compound, dynamic, and multi-joint strengthening exercises that target different muscle groups can help maintain and build muscle mass. Adequate protein intake is also essential, as protein contributes to muscle synthesis and recovery.
In conclusion, while running does not directly consume muscles, it can be a factor in muscle loss if it replaces strength training, creates a significant calorie deficit without adequate nutrition, or is not complemented by proper training strategies and nutrition. To maintain and build muscle mass while running, it is essential to incorporate strength training, ensure sufficient calorie and protein intake, and follow a well-rounded training regimen that includes resistance exercises.

Running is more efficient with smaller muscles
Running long distances can cause muscle loss, but this is not due to the running itself. Instead, it is caused by a lack of complementary strength training and a calorie deficit. In fact, running is more efficient with smaller muscles.
The notion that running consumes muscles is a myth. It is often observed that elite distance runners have slim physiques, with slim thighs and smaller-than-average calves. However, this is not due to running alone. Distance runners tend to have low body fat and lean, mostly slow-twitch muscle fibres. While they do engage in strength training, their goal is to optimise their body shape for running, which means targeting strength and eccentric load resilience rather than muscle growth.
The body prioritises efficiency, and running long distances is more efficient with smaller muscles. As muscles budget less energy for maintaining mass, the fast-twitch fibres in endurance-trained muscles begin to shrink, while slow-twitch fibres grow. This results in smaller, more physiologically efficient muscles.
To prevent muscle loss while running, it is important to incorporate strength training and ensure adequate nutrition. Research has shown that aerobic training, such as long-distance running, can enhance the effectiveness of strength sessions. Additionally, strength training improves running economy and increases time to exhaustion at maximal aerobic speed.
Furthermore, good nutrition is crucial for building and maintaining muscle mass. A calorie surplus, consisting of fresh, wholesome, balanced meals with sufficient protein, supports the muscle-building process.

Running and weight training can be mutually beneficial
Running and weight training can indeed be mutually beneficial. While it is true that running can lead to muscle loss, this is not due to the act of running itself, but rather a lack of complementary training and adequate nutrition.
Firstly, running increases blood flow, which aids in recovery between intense strength training sessions by reducing soreness. Research has also shown that aerobic training, such as long-distance running, can enhance the effectiveness of strength sessions. For example, a Norwegian study found that maximal strength training, in addition to normal endurance training, improved running economy and increased time to exhaustion at maximal aerobic speed. Additionally, strength training can help prevent injuries commonly associated with running by strengthening muscles and connective tissues, and it can improve running form and speed by enhancing neuromuscular coordination and power.
Secondly, adequate nutrition is crucial for building and maintaining muscle mass. Running long distances without increasing food intake accordingly can lead to a calorie deficit, which can hinder muscle development. However, this can be mitigated by ensuring a calorie surplus through a balanced and nutritious diet.
Furthermore, while it is true that endurance training can lead to smaller muscles, this is because it is more efficient to run with smaller muscles. This does not mean that runners should avoid weight training, as resistance training has benefits beyond aesthetics. Competitive endurance athletes will still get stronger, even without significant increases in muscle size, due to nervous system adaptations.
In conclusion, combining running and weight training can be a successful strategy for optimizing fitness. Running can improve recovery and enhance the benefits of strength training, while weight training can improve running performance and help prevent injuries. Adequate nutrition is also key to ensuring the benefits of both running and weight training are fully realized.

Running and strength training can help prevent injury
Running long distances can lead to muscle loss, but this is not due to the act of running itself. Instead, it is because long-distance running does not work the muscles enough or in the right way. Additionally, if you are running a lot and not increasing your food intake, you risk running a calorie deficit that can halt or reverse muscle development.
Running and strength training can complement each other and help prevent injuries. Strength training can help runners improve their performance and prevent injuries by strengthening muscles and connective tissues. It can also improve neuromuscular coordination and stride efficiency, allowing runners to run faster and with better form.
To incorporate strength training effectively, runners should aim for two to three sessions per week at low to moderate intensity. It is important to start slowly and focus on good technique with basic movements such as squats and deadlifts, and simple hip and core exercises. As you progress, you can incorporate more systemic movements and plyometric (jumping) exercises.
Additionally, lower-intensity endurance exercises can help build the aerobic capacity of fast-twitch muscle cells, which are essential for strength and power. It also increases blood flow, aiding in recovery between intense strength training sessions.
Overall, combining running with strength training can be beneficial for improving performance, preventing injuries, and maintaining muscle mass.
