Using stiffness measurements and continuous motion capturing, we found that prolonged sitting periods without regular muscle contractions significantly increased back muscle stiffness.
Research has linked sitting for long periods of time with a number of health concerns. They include obesity and a cluster of conditions — increased blood pressure, high blood sugar, excess body fat around the waist and unhealthy cholesterol levels — that make up metabolic syndrome.
“Sitting all day will make the front of your body tighten up—especially your hip flexors, rectus femoris (a quad muscle), pectoralis (chest), upper traps (upper back), and anterior scalenes (the front of your neck),” explains David Reavy, a Chicago-based orthopedic physical therapist at React Physical Therapy.
Leg pain after prolonged periods of sitting can indicate some venous insufficiency, where our circulation is affected due to our constant sedentary posture.
Legs and gluteals (bum muscles)
Sitting for long periods can lead to weakening and wasting away of the large leg and gluteal muscles. These large muscles are important for walking and for stabilising you. If these muscles are weak you are more likely to injure yourself from falls, and from strains when you do exercise.
It can be due to reduced blood flow, tight muscles and ligaments, fluid pooled in the body's lower extremities, or pins and needles sensations in the feet.
You may be able to treat muscle stiffness at home with rest, massage, and application of heat or cold. Heat may work better for muscle tightness. Cold may work better for swelling and inflammation. Options include hot and cold packs, heating pads, and heat therapy patches.
The most common cause of muscle stiffness is a sprain or strain, which can affect both the muscles and ligaments. A strain is when the muscle fibers are stretched or torn. Strains are particularly common in the legs and lower back. A sprain is when the ligaments have been stretched, twisted, or torn.
See your doctor as soon as possible if you have: Signs of infection, such as redness, warmth or tenderness, or you have a fever greater than100 F (37.8 C) A leg that is swollen, pale or unusually cool. Calf pain, particularly after prolonged sitting, such as on a long car trip or plane ride.
The most common causes of muscle pain are tension, stress, overuse and minor injuries. This type of pain is usually localized, affecting just a few muscles or a small part of your body.
LOW risk indicates sitting less than 4 hours per day. MEDIUM risk indicates sitting 4 to 8 hours per day. HIGH risk indicates sitting 8 to 11 hours per day. VERY HIGH risk indicates sitting more than 11 hours per day.
But when experts analyze the handfuls of studies examining the effects of prolonged sitting, the data shows that sitting for more than eight hours a day can have a serious impact on a person's health.
In particular, standing for prolonged periods is associated with varicose veins and back pain, he said. To get the right balance, Hedge recommends sitting 20 minutes out of every half hour at work, standing for eight minutes and moving around for at least two minutes.
Mobility, or full-range, exercises like walking or easy cycling lead to more blood pumping through the muscles. This increase in blood flow may help you recover from soreness sooner. That is, as long as you aren't overloading or challenging the muscles more.
It is one of the more common symptoms of MS. Spasticity may be as mild as the feeling of tightness of muscles or may be so severe as to produce painful, uncontrollable spasms of extremities, usually of the legs. Spasticity may also produce feelings of pain or tightness in and around joints, and can cause low back pain.
The main cause of heavy legs is generally poor blood circulation. Blood circulation problems generally occur in the lower part of your body, especially your legs. This is because the lower section of your body needs to fight against gravity to transfer the blood back up to your heart.
Despite a widespread belief that little can be done about stiffness other than surgery, appropriate physical therapy can relieve and even reverse stiffness.
It can affect people of all fitness levels, particularly after trying a new activity or pushing yourself a bit harder than usual. Usually your muscles will stop aching in 2 to 5 days and you won't need any medical attention. You should be able to ease symptoms yourself.
Arthritis is not the only condition associated with joint stiffness. Other medical conditions can also cause joint stiffness, including bone diseases, cancer, joint trauma, or overuse of the joint.
If you get sore muscles once in a while, you can take acetaminophen or a nonsteroidal anti-inflammatory drug (NSAID) like aspirin, ibuprofen, or naproxen to help ease the discomfort. Just be cautious about using NSAIDs regularly.
Muscle rigidity is often triggered by stress. Stress can adversely affect your body's nervous system — including your nerves — and how they function. Your nervous system may respond to stress by putting additional pressure on the blood vessels, which results in reduced blood flow to the muscles.
The muscle-tendon complex becomes more rigid and, since tendon stiffness is reduced in elderly, muscle stiffness is expected to increase. Such increase is likely due to change in ECM and connective tissue, although some data on single fibers also suggest a contribution due to increased stiffness of single fibers.
