Pulling a muscle, also known as a muscle strain or tear, is a common but painful injury. It occurs when a muscle is overstretched or torn, causing damage to the muscle fibres and, in some cases, the tendons attached to them. The injury can range from mild to severe, with mild strains causing minor damage and severe strains resulting in a complete tear of the muscle. Acute muscle strains happen suddenly, while chronic strains develop over time. Treatment for a pulled muscle typically involves rest, ice, elevation, and pain relievers, but in some cases, medical care may be required.

Muscle strains are tears in muscle fibres
Muscle strains, or pulled muscles, are common yet painful injuries. They occur when the fibres of a muscle tear, either suddenly or gradually. This can happen when a muscle is stretched beyond its elastic limit, pulled too hard, overused, or used too much without rest. The severity of a muscle strain can vary from mild to severe. A mild strain might only break a few tiny fibres within the muscle, while a severe strain can tear it completely.
Muscle strains are often sports injuries, as they are frequently caused by sudden sprinting, twisting, or jumping. They commonly affect the hamstrings, quadriceps, and gastrocnemius, which are biarthrodial muscles that cross two joints, making them more vulnerable to injury. A muscle is most likely to tear during sudden acceleration or deceleration. Strains can also occur in everyday life, caused by repetitive movements, overtraining, or undertraining.
The healing process for a muscle strain can take anywhere from 3 to 16 weeks, depending on the severity of the injury. During this time, the muscle is at an increased risk of sustaining a second injury due to decreased strength and stiffness. Treatment for a pulled muscle often involves rest, ice, compression, and elevation (RICE). However, severe tears may require medical care or even surgery.
Muscles are made of thousands of small fibres woven together, and they enable our bodies to move. They work in conjunction with the bones of the skeleton to generate force and movement. There are three types of muscle tissue in the human body: skeletal, smooth, and cardiac. Skeletal muscles are voluntary muscles that move when you think about moving a part of your body. They are attached to bones by tendons.

Strains can be acute or chronic
Strains can vary in severity, from mild to severe, and they can be acute or chronic. Acute muscle strains are caused by a sudden tear in the muscle fibres, which can happen during sports or other physical activities. They can also be the result of repetitive movements, such as those performed in the workplace or during recreational activities. Acute strains often cause immediate pain and a feeling of weakness in the affected muscle.
Chronic muscle strains, on the other hand, develop over time due to repetitive movements. This could be due to holding your body in an awkward position for extended periods, such as when working at a desk. Chronic strains may cause a gradual increase in pain over several days and can lead to muscle weakness.
Acute muscle strains are more common in cold weather, as muscles are stiffer at lower temperatures. It is important to take extra time to warm up before physical activity in cold conditions to prevent acute strains. Additionally, maintaining proper form during physical activity can help prevent both acute and chronic strains. This includes warming up before exercising, stretching regularly, and practising strength training to build muscle resilience.
The treatment for acute and chronic strains can vary depending on the severity of the injury. Most mild to moderate strains can be treated at home with rest, ice, compression, and elevation (RICE). However, severe strains may require medical attention, physical therapy, or even surgery in some cases. It is important to allow enough time for the muscle to heal properly to prevent re-injury and the formation of scar tissue, which can increase the susceptibility to future injuries.

They can be treated at home
When a muscle is pulled or strained, it can often be treated at home without the need for medical intervention. Here are some guidelines on how to treat a pulled muscle and promote healing:
Rest: Take a break from any physical activity that caused the strain and avoid any movements that may be painful or uncomfortable. Modify your activities to ensure you are giving the injured muscle time to heal.
Ice: Apply ice packs to the affected area to reduce swelling and pain. Wrap the ice pack in a thin towel and apply it to the injured area for 15-20 minutes at a time, several times a day. Do not apply ice directly to the skin as it may cause ice burns.
Compression: Compress the muscle with an elastic bandage or compression sleeve to reduce swelling and provide support. Ensure that the compression is firm but not tight enough to restrict blood flow. Start at one end and wrap in an overlapping pattern towards the heart.
Elevation: If possible, elevate the injured area above the level of your heart to minimize swelling. Prop it up on pillows or cushions when sitting or lying down.
Non-steroidal anti-inflammatory drugs (NSAIDs): Take over-the-counter pain relievers such as ibuprofen or naproxen to reduce pain and inflammation. Always follow the dosage instructions on the package or consult your pharmacist or doctor for advice.
Gentle stretching and massage: Once the initial inflammation has reduced, usually after 48-72 hours, gently stretch the affected muscle group to promote blood flow and flexibility. You can also try self-massage or use a foam roller to gently massage the area, promoting circulation and breaking up any scar tissue that may have formed.
Gradual return to activity: When pain and swelling have significantly reduced, you can gradually reintroduce light activities and see how your muscle responds. Start with gentle ranges of motion and low-impact exercises, gradually increasing the intensity and duration of your workouts over time.
It is important to listen to your body and not rush the healing process. If pain or swelling returns, it is a sign that you need to scale back your activities and give the muscle more time to heal. Most muscle strains heal well with conservative at-home treatments, but if symptoms persist or worsen, it is important to seek medical advice from your doctor or a sports medicine specialist.

Rest and ice are recommended
When a muscle is pulled or strained, rest and ice are recommended as part of the RICE (Rest, Ice, Compression, Elevation) method. This is a common and effective treatment for mild to moderate muscle strains. The RICE method helps to relieve pain, reduce swelling and inflammation, and expedite the recovery process.
Rest is crucial after a muscle strain to allow the muscle time to heal. It is important to stop moving the affected area and avoid physical activity, as continuing to exert the muscle can worsen the injury and delay healing. The amount of rest needed will depend on the severity of the strain, and it is important not to rest for too long, as this can lead to stiffness and weakness.
Ice is applied to the injury to reduce swelling, local bleeding, and pain. It is recommended to use ice as soon as possible after the injury, multiple times a day for up to 20 minutes at a time, for about 72 hours. Ice causes blood vessels to narrow, reducing blood flow and inflammation. After the initial 72 hours, it is recommended to switch to heat therapy to increase blood flow and speed up recovery.
Compression and elevation are also important components of the RICE method. Compression involves applying gentle pressure to the muscle with an elastic bandage or tape, which helps prevent swelling and provides support to the injured area. Elevation involves keeping the injured area raised above the heart when sitting or lying down to reduce swelling.
While the RICE method is effective for minor to moderate muscle strains, more severe cases may require additional treatment, such as medication, physical therapy, or, in the case of a complete muscle tear, surgery. It is important to seek medical advice if the injury is severe or if there is no improvement with the RICE method.

Severe strains may require surgery
While most muscle injuries can be managed at home using the RICE method (rest, ice, compression, and elevation), severe strains may require surgery.
Muscles are made of thousands of small fibres woven together, and these fibres stretching and pressing together is what moves your body and organs. When you have a muscle strain, some of these fibres tear or stretch beyond their limits. Most of the time, this damage is minor, and the muscle can heal itself with time and rest. However, in severe cases, the muscle fibres may tear completely or detach from the bones or tendons they are attached to. This is known as a grade 3 muscle strain.
Surgery may be necessary for grade 3 muscle strains to repair the torn muscle fibres and reattach them to the bone or tendon. The specific surgical procedure will depend on the location and severity of the injury. For example, a severe strain in the leg may require surgery to reattach the muscle to the bone, while a severe strain in the arm may require surgery to repair torn muscle tissue.
In some cases, surgery may also be recommended for chronic muscle conditions that have not responded to non-surgical treatments. Surgery can help to improve function and reduce pain in the affected area. However, it is important to note that surgery is always associated with risks, including infection, bleeding, and anaesthetic complications. Therefore, the decision to undergo surgery should be made in consultation with a healthcare professional.

Frequently asked questions
PR stands for Personal Record. It refers to your personal best for a specific fitness achievement, such as lifting your heaviest weight or completing your highest number of reps.
It's important to set reasonable goals. For example, if your client's previous record in weightlifting was 95 pounds, a reasonable increase would be 100 pounds. Larger increases may result in injury. It's also beneficial to measure progress in other ways, such as tracking muscle growth or body weight changes.
Weightlifting and powerlifting exercises such as the bench press and squat are common choices for setting PRs. However, PRs can be set for any fitness achievement, including running, where a PR might be a new best race time or per-mile pace.
