Nous pensons souvent que les tensions musculaires sont le contrecoup d'une séance d'entraînement particulièrement intense, et bien que cela puisse être vrai, tu peux aussi avoir des muscles douloureux et crampeux pour toute une série de raisons en dehors de l'exercice. Tu as peut-être passé plus de temps que d'habitude assis à ton bureau alors que tu travaillais sur un projet, pour ensuite remarquer des tensions dans le haut du dos et le cou après t'être levé. Ou bien, tu as peut-être fait une tonne de travaux de jardinage pendant le week-end, et maintenant ton dos et tes biceps sont tendus et douloureux. 

Les tensions musculaires font partie intégrante de la vie quotidienne, explique Julianne Payton, Physiothérapeute, DPT, Physiothérapeute chez Hinge Health. "Les tensions musculaires peuvent apparaître à de nombreux endroits différents et peuvent aller et venir", dit-elle. Bien que les muscles tendus puissent être un peu inconfortables ou frustrants, ils ne sont généralement pas une cause d'inquiétude. Et il y a beaucoup de choses que tu peux faire pour soulager l'inconfort.

What Is Muscle Tightness?

“Most people think muscle tightness is only due to muscles and tendons shortening,” says Dr. Payton. "But how stiff you feel is due to a lot of factors, including soreness, pain, or lack of movement." 

And tightness, in part, is a protective mechanism. For example, if you sat for two hours in a chair, going straight into a sprint might not be the best idea. So some tightness can serve as a reminder to warm up first. Feeling stiff after an injury might remind you to take it easy with certain movements for a few days. “Strengthening and stretching a tight muscle can ease many factors that contribute to muscle pain," says Dr. Payton.

Symptoms of Muscle Tightness

The symptoms of muscle tightness will vary depending on which muscles are affected. But in general, there are four main areas of your body where you’re more likely to notice muscle tightness, notes Dr. Payton. These include:

• Your hamstrings. “You’ll notice a tightness in the back of your leg, from near your glutes all the way down to your knee,” says Dr. Payton. You’ll feel this tightness especially when you sit, or when you try to stretch the area. 

• Upper trapezius muscles. These are the muscles that travel from the side of your neck down towards your shoulders. “It’s really common for people to hold tension and stress in this area,” says Dr. Payton. As a result, these muscles can feel very tight.

• Hip flexors. “You may notice a feeling of tightness through your lower back that travels to your hips,” says Dr. Payton. It may get worse when you walk and be especially pronounced when you stand after sitting for a long time.

• Calf muscles. Tight calves usually result in tightness at the back of the lower legs when you walk.

Muscle Tightness: A Hinge Health Perspective

If your muscles feel tight, it’s understandable that you may be reluctant to move, especially if you experienced more tightness after being active. But know this: Movement is often the fastest way to a healthier, more flexible body. As our Hinge Health care team says, movement is medicine. Movement helps rehab sore muscles by increasing blood flow, and gradually improving the muscle’s strength and flexibility. 

Your muscles — especially the big muscle groups that are prone to tightness — are very resilient and designed to recover from the kinds of issues that naturally can happen in the course of everyday activities or during exercise.

A well-rounded cardio, strength, and stretching routine can help to keep your muscles healthy and prevent tightness and pain. A physical therapist can also work with you on a strengthening and stretching plan that targets your affected muscles. You can see a physical therapist in person or use a program like Hinge Health to access a PT via telehealth/video visit.

Causes of Muscle Tightness 

What causes tight muscles? There can be a few reasons, says Dr. Payton. They include:

• Delayed onset muscle soreness (DOMS). “When you do a tough workout, muscle soreness is common,” says Dr. Payton. “This is often an initial side effect as your body becomes stronger.” Usually the soreness is less pronounced after your second workout. But if you find the amount of soreness or stiffness to be too disruptive or too painful, reach out to a physical therapist on how to modify your workouts.

• Muscle strain. “When you pull a muscle, you may notice tightness or tension — it’s your body’s way of protecting the injured area while it recovers,” says Dr. Payton.

• Sitting too much. If you’re sedentary in the same position for much of the day, like when working at a desk, you may experience tense, tight muscles over time. “Our muscles aren’t designed to stay in the same position for long,” says Dr. Payton. “When they do, they can tighten up.” 

• Stress. If you’re frazzled or anxious, it’s common to unconsciously tense certain muscles, like the shoulders, for instance, which can lead to tightness and neck pain.  

Treatment Options for Muscle Tightness

The following tips from our Hinge Health physical therapists and medical doctors can provide relief for tight muscles:

• Heat. “I get a lot of questions from patients on how to relax muscles, and oftentimes heat is best,” says Dr. Payton. She recommends that you apply heat, like a hot water bottle or warm wet towel, for five to 10 minutes before doing the stretches below.

• Physical activity. Movement and exercise may feel counterintuitive if your muscles are stiff and tight, but they truly help to relieve symptoms. “They increase blood flow to the affected muscles, which helps relax the area,” says Dr. Payton. If you feel particularly stiff, consider a water workout — a 2021 review found that it can help relieve muscle stiffness. 

• Foam rolling. Research suggests this technique may help to loosen stiff muscles. Use a foam roller on the tight area for a few minutes before you work out.

• Physical therapy. A physical therapist can provide advice on how to relieve body stiffness with tailored exercises for your affected muscles. 

• Deep breathing exercises. “Shallow breathing, like when you’re stressed, tightens your muscles,” says Dr. Payton. “But deep breathing exercises help your whole body relax, so that your muscles can relax, too.” She recommends box breathing, where you breathe in through your nose as you count to four, hold your breath for a count of four, and then exhale for another count of four.

• Healthy eating. Dehydration can contribute to muscle tightness, so focus on consuming plenty of fluids throughout the day. Aim to drink for half your body weight in ounces of water. You also want to make sure that you get enough magnesium and calcium in your diet, since they are both key for muscle health. You can usually get enough through foods like avocados, bananas, dairy products, dark leafy greens, fatty fish, fortified orange juice, and nuts and seeds.
