Running is a popular form of exercise, with people taking it up for a variety of reasons, including to reduce stress, improve health, and compete in races. It is also a good way to build muscle, particularly in the lower body. However, it is important to stretch before and after running to prevent muscle soreness and injury. While running itself does not increase flexibility, regular runners may find themselves more flexible due to the increased time spent stretching.

What You'll Learn

Running does not increase flexibility
Running is a great form of exercise that can help improve health, reduce stress, and aid weight loss. However, it is important to note that running does not directly increase flexibility. In fact, running, especially long-distance running, can lead to muscle tightness and stiffness if not properly managed.
To prevent muscle tightness and maintain flexibility while running, it is crucial to incorporate stretching into your routine. Static stretching, such as reaching down to touch your toes, can be beneficial, but it may not be the most effective method. Instead, dynamic stretches that replicate the motions of your workout are recommended. These stretches allow for a controlled and gradual stretch of the muscles. Additionally, activities like yoga and Pilates can be excellent complements to your running routine, enhancing flexibility and aiding in recovery.
It is also worth noting that proper warm-up and cool-down routines are essential for runners. A warm-up helps prepare your body for the upcoming physical activity, reducing the risk of injury. Similarly, a cool-down routine allows your body to gradually transition to a resting state, promoting recovery.
Furthermore, muscle tightness in runners can be a result of muscle weakness or fatigue. To address this, consider incorporating strengthening exercises into your routine. Recent research suggests that performing slow, heavy eccentric exercises can lead to a process called sarcomerogenesis, where new microscopic muscle units are added, potentially improving flexibility.
While running may not directly increase flexibility, combining it with stretching, yoga, and strengthening exercises can help maintain and improve your overall flexibility and range of motion. Additionally, proper nutrition and refueling after runs are crucial for muscle recovery and maintaining overall health.

Running can build lower body muscles
Running is an excellent form of aerobic exercise that can help build lower-body muscles, particularly in the quadriceps and hamstrings. High-intensity, short-duration running workouts like High-Intensity Interval Training (HIIT) have been shown to effectively build leg muscles.
In a study, 12 recreationally trained college students performed HIIT workouts involving 4 sets of running at near maximum capacity for 4 minutes, followed by 3 minutes of active rest. After 10 weeks of these workouts 3 times per week, they exhibited an 11% increase in the muscle fiber area of their quadriceps compared to a control group.
Additionally, varying your running training can help develop muscular legs. For example, long-distance runners can include sprint work or hill training to improve quad and calf strength, while sprinters can incorporate long runs to strengthen their hamstrings.
It is important to note that running alone may not be sufficient for optimal muscle growth. Good nutrition, adequate rest, and proper stretching are also crucial components of a well-rounded training regimen. Ensuring your body receives the necessary nutrients, especially protein, supports the muscle-building process.
Furthermore, proper stretching before and after running can help prevent injuries and enhance recovery. Dynamic stretches that replicate the motions of your workout are ideal for warming up the muscles, while static stretches can be incorporated after your run to improve flexibility and reduce muscle tightness.

Running can cause muscle soreness
To prevent and manage muscle soreness, it is important to stretch before and after your runs. The type of stretching has evolved over time, with a shift towards dynamic movements instead of static bend-and-touch-your-toe stretches. Dynamic stretches involve replicating the motions of your workout, allowing the muscles to be slowly stretched in a controlled manner. Static stretches, on the other hand, involve holding a position at the point of mild discomfort for at least 30 seconds. While static stretches are not ideal before a run, they can be beneficial after a run to improve flexibility.
In addition to stretching, foam rolling can help ease muscle soreness by enhancing circulation, reducing inflammation, removing scar tissue, and improving the range of motion. It is important to note that rolling should not be done on sore areas, as it can make things worse. Instead, work around the sore area, and ensure that it is mildly uncomfortable but not painful.
Nutrition also plays a crucial role in muscle recovery. Refuelling within 30 minutes, ideally with a 4:1 carbohydrate-to-protein ratio snack, is recommended to provide the body with the energy needed to repair and recover. Examples include a smoothie, a banana with peanut butter, or chocolate milk.
Finally, if you are experiencing sharp, acute pain, it is important to consult a doctor. Muscle soreness that does not alleviate after 48-72 hours is a sign of overexertion, and dark tea-coloured urine or muscle bruising without trauma are indicators of rhabdomyolysis, a life-threatening condition requiring immediate medical attention.

Running can help with back pain
However, it is important to note that running may not be suitable for those with structural spine problems. If you are experiencing back pain, it is always a good idea to consult with a doctor or healthcare professional before starting a new exercise routine.
To run safely with back pain, it is important to stretch before and after your run. Hamstring, quadriceps, groin, and calf stretches are particularly important for preventing and easing back pain, as the thigh muscles connect to the pelvis and hips, which can affect the back. It is also recommended to start slowly and ease into a running routine, rather than starting with a long or intense run.
Proper nutrition is also key to supporting muscle recovery and preventing back pain. Eating a snack or small meal with a 4:1 carbohydrate to protein ratio within 30 minutes of your run is ideal for refueling and starting the recovery process. Examples of good post-run snacks include a smoothie, a banana with peanut butter, or chocolate milk.
In addition to stretching and nutrition, foam rolling can also help to ease muscle soreness and tightness associated with back pain. Foam rolling can enhance circulation, reduce inflammation, and improve the range of motion. However, it is important to avoid rolling over tendons, bones, and sore areas, as this can cause further pain and injury.

Stretching before and after running is important
Additionally, stretching helps to improve the quality of your workout by gradually decreasing the heart rate and allowing it to return to normal. It also helps to remove lactic acid from the muscles, which improves recovery. Finally, stretching can help to improve flexibility and reduce muscle tightness, soreness, and stiffness. For example, a runner may experience tightness in their calf muscles after a run, and stretching these muscles can help alleviate this issue.
It is important to note that the type of stretching and the specific stretches performed are crucial. The guidance on stretching has evolved over time, with a shift from static stretching towards dynamic movements. It is also essential to perform the stretches correctly and to maintain symmetry in the movement and strength of the body to avoid injuries.

Frequently asked questions
Running does not loosen muscles. In fact, running can cause muscle tightness if you don't stretch or roll your muscles regularly.
It is important to stretch before a run to warm up your muscles. Your pre-run warm-up should include dynamic movements that replicate the motions of your workout. This allows the muscles to be slowly stretched in a controlled manner.
You can try foam rolling, which can provide a range of benefits, including enhanced circulation, reduced inflammation, and improved range of motion.
Yoga and Pilates can help with flexibility and faster recovery. You can also try a sports massage, which can combine deep pressure on the muscle with stretches to loosen the offending muscle.
Running can build lower body muscles, but it depends on the intensity and duration of your runs. High-intensity, short-duration running workouts like HIIT can help build lower body muscle, especially in your quadriceps and hamstrings.
