When Muscles are Sore After a Workout

When muscles are sore after a workout, it is important to understand why this is happening and how to properly take care of the situation.


When it comes to exercising and physical activity, muscle soreness is an inevitable consequence. It is an indication of having worked out hard during a session and causes a certain level of discomfort. It usually occurs 12 to 24 hours after a workout, but can also be experienced up to 72 hours later. This type of soreness can range from minor aches and stiffness, causing only mild discomfort, to somewhat severe pain that limits flexibility and mobility for a period of time.

The cause of such muscle soreness is increased blood flow from exercise that adds oxygen and nutrients to the affected muscles through increased circulation. This allows for the repair process needed for further development in strength and endurance. Knowing how to properly handle post-workout muscle soreness can be beneficial in minimizing it or even avoiding it altogether. With this knowledge you can avoid hindering any workout progression you may have made in recent active sessions or prepare for those sessions prior.

Causes of Muscle Soreness

After a challenging workout, it is common to feel sore in various muscle groups. This feeling is called delayed onset muscle soreness (DOMS) and is caused by tiny tears in the muscle fibers that are required to adapt to new levels of activity. Understanding the causes of muscle soreness can help you develop an effective plan to help prevent and reduce its occurrence in the future.

Delayed Onset Muscle Soreness (DOMS)

Delayed onset muscle soreness (DOMS) is a type of discomfort that can develop hours to days after engaging in physical activity. It can range from mild pain to severe swelling that limits activity and mobility. Several factors contribute to DOMS, including lactic acid buildup, muscle fibers being damaged from exercise, inflammation, unnatural movement patterns of the body and excessive stretching.

DOMS is common for those who are transitioning from sedentary lifestyle to exercising or increasing the intensity or duration of their activities too quickly. It can occur following a workout where one has elevated their heart rate for an extended period with challenging exercises or activities such as aerobics, weightlifting, running or even everyday tasks such as yard work or shoveling snow.

The most effective way to alleviate DOMS pain is through rest and gentle massage therapy utilizing circular motion on the affected areas to break down the tenderized tissues. Additionally ice packs or cold therapy treatments will reduce inflammation and assist with healing while heat treatments such as a hot tub bath can help loosen the muscles up allowing the individual to move more freely when they feel ready to resume their normal routine activity level. Stretching techniques have also been proven beneficial at eliminating any residual soreness and helping prevent future DOMS episodes.

Muscle Fatigue

Muscle fatigue is one of the primary causes for muscle soreness after a workout. When muscles are repeatedly contracted, the body does not have time to replenish its energy stores, resulting in a decrease in muscle force during successive contractions. This reduction in force is called muscle fatigue and is usually experienced as an increase in muscular effort or difficulty with movement. Muscle fatigue can occur due to a lack of oxygen, electrolyte imbalance, dehydration, improper warm-up, cumulative microtraumas to the muscle fibers from strenuous activity or excessive exercise intensity.

The effects of fatigue can be cumulative and include increased injury risk, joint stiffness and decrease in strength. Post-workout soreness generally occurs 24–72 hours after exercise but may last up to 5 days if too much force was expended during the workout or if too little rest was taken between workouts. Athletes should monitor their workloads closely so they can identify any problems before they cause major issues with their performance or recovery times.

Prevention of Muscle Soreness

Post-exercise muscle soreness is a common phenomenon amongst those who exercise regularly. It can range in intensity, ranging from mild aching to severe soreness in some cases. Fortunately, there are several steps you can take to prevent muscle soreness in the first place. This article will discuss the various methods of preventing muscle soreness, from simple stretches to nutritional strategies.

Warm Up and Cool Down

Engaging in a proper warm-up and cool down when you exercise is essential to preventing muscle soreness after a workout. Before starting a strenuous physical activity, it is important to warm your muscles up, which increases your body temperature and increases circulation. Warming up should include dynamic stretching and light cardiovascular exercises such as jogging or biking. This allows the muscles to be ready for more intense exertion. When you have completed your exercise session, it’s also important to cool down with a variety of stretches, breathing exercises, and yoga poses that will help your body relax. Cooling down helps reduce muscle fatigue, increases flexibility, improve range of motion and can prevent post-workout muscle soreness.

Proper Form and Technique

Proper form and technique are paramount to effective workouts as well as prevention of muscle soreness. Making sure to use the correct form for each exercise will help to ensure that muscles are worked in the way they were designed for. Incorrect form can lead to muscle strains and soreness, as well as injury when momentum is used instead of your muscles.

Focus on performing each exercise slowly and methodically; this will help you learn proper technique and balance while avoiding excessive strain on your body. Additionally, be sure to use appropriate weights that can be moved with correct form. Lifting weights too heavy for your strength level can result in improper mechanics, excessive muscle fatigue and post-workout pain and discomfort. Always talk with a certified professional such as a physical trainer or physician if you have any questions about technique or safety guidelines before beginning any workout program.

Proper Nutrition and Hydration

Adequate nutrition and hydration is an important part of preventing muscle soreness after a workout. Eating a balanced diet with whole grains, lean proteins, fresh fruits and vegetables, and healthy fats can help to promote muscle recovery following exercise. Hydrating before, during and after a workout with water or electrolyte drinks can also ensure your muscles are getting what they need for recovery. Additionally, it is important to reduce your consumption of processed foods, sugar, caffeine and alcohol which can be inflammatory and interfere with proper muscle recovery.

The body also needs certain nutrients to help repair the muscles that have experienced damage from physical activity. Protein is essential for repairing muscles and can be found in foods such as meat, poultry, eggs, fish or soy products. Other nutrients such as Omega-3 fatty acids and antioxidants that protect tissue against oxidation damage are found in foods like nuts, seeds, olive oil and green leafy vegetables. Be sure to consume enough calories per day in order to maintain energy levels while working out. Lastly vitamins such as A (found in egg yolks) C (found in citrus fruits) B6 (found in bananas) and B12 (found in dairy products) as well as minerals like magnesium (found in legumes) calcium (found in dairy), iron(found in fortified cereals), zinc(oysters), sodium(salt) are all important for helping your body repair itself after exercise.

Treatment of Muscle Soreness

Muscle soreness after a tough workout can be debilitating. If you experience muscle soreness, the best way to treat it is to ensure that you get adequate rest and nutrients to help with the healing process. Additionally, there are various treatments available to reduce muscle soreness, including stretching, massage and topical treatments. In this article, we will be looking at these treatments in more detail.


Massage therapy can help to reduce muscle soreness and improve performance after exercise. It not only helps to reduce pain and tension, but also increases circulation and muscular relaxation, which can help your muscles recover faster. Sports massage therapists are specially trained in techniques that effectively target every area of the body to encourage better circulation and improve flexibility. This type of massage may include deep tissue manipulation and myofascial release techniques to aid recovery by improving elasticity in tight muscles. It also helps break down scar tissue buildup caused by intense activities, which can inhibit performance and increase risk of injury.


Stretching may help treat muscle soreness and reduce delayed onset muscle soreness (DOMS) after a workout. Stretching can help improve flexibility, reduce tension, and ease the ‘knots’ in your muscles that lead to soreness. To stretch effectively, you should do some gentle stretching after a workout when your muscles are already warm and hold each stretch for at least 15-30 seconds. Be sure not to overstretch, as it can cause more harm than good if you don’t do it properly.

Static stretching is the most commonly used type of stretching. It involves gently stretching your muscles slowly and steadily without bouncing or jerking movements until the appropriate level of tension is achieved. Dynamic stretching, on the other hand, is when you use repetitive movements to gradually increase range of motion without breaking technique. Examples of dynamic stretches include high knees, butt kicks or arm circles.

Stretching after a workout helps improve recovery time by increasing circulation to stiff areas and releasing muscle tension built up during exercise. While your body needs time to rest and recover after a tough workout session, regular stretching benefits health in various ways including maintaining muscular balance and reducing rehabilitation time for injuries or overuse syndromes such as tendinitis or bursitis.

Ice and Heat Therapy

When muscles are sore after a workout, ice and heat therapy are two treatments that can be used to help relieve tension and inflammation. Ice therapy is commonly used to reduce swelling and pain when used immediately following an injury. It is typically applied in the form of an ice pack or cold compress applied directly over the affected area for 10 – 15 minutes at a time, up to several times per day.

Heat therapy, on the other hand, is used to relax muscles and improve circulation. When applying heat to sore muscles, it is best done 30 minutes after or even 24 hours after exercise. Heat can be applied through a warming pad or with hot water bottles as long as the temperature isn’t too hot as this may worsen any existing inflammation. 10 -15 minutes at a time should suffice before taking a break for 30 minutes before reapplying again if needed.

Both treatments should be used with caution when dealing with muscle soreness, as each brings its own risks and potential benefits depending on your individual condition or injury. If in doubt always consult with your doctor before beginning any type of treatment to avoid potential risks or further injury.


In conclusion, being sore after a workout is normal and should be expected. To help reduce the soreness, it is important to properly stretch before and after the workout, drink plenty of water before, during, and after the workout, eat a healthy diet with plenty of protein following your exercise routine, and get adequate rest. Additionally, moderate forms of exercise such as foam rolling or cold air baths may help reduce muscle soreness. It is also important to consult with a physician if any muscle pain is intense or lasts for more than a few days. With proper practice and care, you can exercise regularly without having to worry about delayed onset muscle soreness.
