When a muscle contracts, it shortens. Take the biceps for example. Without getting too technical, the biceps are attached at the forearm and shoulder. When your biceps contract, they shorten and bring those two points closer together. When you rest, the muscle returns to its normal length, and the two points move farther away. Constantly contracting your biceps over a long period of time would cause them to get shorter, even at rest.
Most back pain is harmless – caused by sleeping in an awkward position, stretched muscles, overexertion, sitting down too long or falling on the ischial tuberosity (the bones of the butt that you sit on), or minor hip injuries caused by twisting a certain way during sports like volleyball. Many injuries arise simply from improper form during exercise, sports injuries, or strains.

The sacroiliac joint connects the lower spine to the pelvis and any injury or strain to this area can cause a lot of back, hip, groin, and sciatic pain. Sacroiliac joint dysfunction (SJD) can cause not only radiating lower back pain but can also severe pain in the hip area including hip pain at night when sleeping and hip pain when sitting. Often the pain resembles that of a hip injury it is so severe. SJD can also cause severe pain in the groin area. Women may also notice pain running along the distribution of the sciatic nerve. Treatment for sacroiliac joint dysfunction includes rest, anti-inflammatory drugs, and sciatic nerve massage.
• Osteoarthritis. The most common form of arthritis of the back, osteoarthritis is a chronic condition characterized by the breakdown of the cartilage that cushions the ends of the bones where they meet to form joints. In the spine, this breakdown occurs in the cartilage of the facet joints, where the vertebrae join. As a result, movement of the bones can cause irritation, further damage and the formation of bony outgrowths called spurs. These spurs can press on nerves, causing pain. New bone formation can also lead to narrowing of the spinal canal, known as spinal stenosis.
Honestly, I am new to a lot of this stuff, so I am definitely not an expert on the subject. However, I have been doing some research on the matter, and it seems most people recommend stretching the opposing muscle group in such cases. For example, if you injured your hamstring, you would stretch your thigh. You would also want to stretch the surrounding muscle groups, seeing as how our entire body is fit together, so that every part of your body affects every other part. I realize that by now you are probably back to skating, but for anyone else who reads this and has a similar issue, I would still suggest looking into it a bit, as, like I said, I am new to a lot of stuff (PE was about as far as I got when it came to exercise, until almost two months ago, when I found crossfit), but at least it’s a start.
• Osteoporosis. Osteoporosis is a condition in which the bones loose so much mass that they become brittle and prone to break with slight trauma. The condition, which can occur with aging, inactivity, a low-calcium diet or use of corticosteroid medications, commonly affects the spine. When this occurs in the spine, the inner spongy bone and more solid outer portion of the vertebrae become porous. The weakened vertebrae can break – an injury called a compression fracture – and lose about one-half of their height. In most cases, compression fractures, are painful. In some cases, the resulting back pain is severe. Usually, the pain resolves within a few weeks, but for some people, it is long-lasting.

There is controversy and scientific uncertainty about trigger points. It’s undeniable that mammals suffer from sensitive spots in our soft tissues … but their nature remains unclear, and the “tiny cramp” theory could be wrong. The tiny cramp theory is formally known as the “expanded integrated hypothesis,” and it has been prominently criticized by Quintner et al (and not many others). However, it’s the mostly widely accepted explanation for now. BACK TO TEXT

To start, get into a lunge position with your right knee up and your left knee on the floor. Rest your hands on the ground, directly underneath your shoulders. Next, flex your raised right knee outward, so that you’re resting on the outside of your right foot. Press your chest forward to increase the stretch. Hold this pose for 10 seconds, then repeat on the other side of your body.
The hip is a very stable ball and socket type joint with an inherently large range of motion. The hip contains some of the largest muscle in the body as well as some of the smallest. Most people lack mobility due to a relatively sedentary lifestyle. Periods of prolonged sitting results in tightness of the hip flexors and hamstrings. Tightness in the muscles and ligaments can created joint forces that result in arthritis, postural problems, bursitis, and mechanical back pain.
Even though it seems like your legs are moving forward and backward when you’re running, in reality, the femur (your thigh bone) both rotates and tilts in the hip socket, Kalika explains. It’s the hip adductors—most notably the gluteus medius—that keeps the femur sitting in the socket as designed. (The hip adductors are the muscles that move your legs inward.) Any weaknesses make the joint unstable, and can contribute to poor running mechanics, hip drop (when the pelvis drops to one side), too-narrow stances, and aggravated tissues throughout the entire body, Sauer says.
The main work of your hip flexors is to bring your knee toward your chest and to bend at the waist. Symptoms associated with a hip flexor strain can range from mild to severe and can impact your mobility. If you don’t rest and seek treatment, your hip flexor strain symptoms could get worse. But there are many at-home activities and remedies that can help reduce hip flexor strain symptoms.
