Flexible, strong, but can be injured under pressure. Who am I? The Achilles Tendon Injury, which is also called the “calcaneal tendon”, known to be the largest and strongest tendon in the body (Fitness & Exercise). The two most common of this injury are Achilles Tendinopathy, and tearing or rupturing of the tendon (Sports Medicine). It is a tough band of fibrous tissue that is connects your calf muscles to your heel bone, which is also called “calcaneus”. If you looked below the skin behind of your ankle you feel the tendon there. However, they are two types of information about the recent of the muscles that's a key. This information is the muscle spindles, found in skeletal muscles, which needs to know the amount of tension in the muscle and its allied tendons (Marieb & Hoehn p.498). According to Marieb & Hoehn, tendon organs are proprioceptors located in the tendons, close to the skeletal muscle insertion. They are consisted of small bundles of tendon “collagen” fibers together in a layered capsule, with sensory terminals coiled between and around the fibers. So when the muscle ...

Flexion is the bending of a joint so that the angle between the two bones decreases. The primary muscles that flex the knee are a group collectively known as “hamstrings.” The hamstrings consist of the biceps femoris, semitendinosus, semimembranosus. The muscles that assist in flexion are the sartorius, gracilis,...
Ankle sprains have three degrees of injury ranging from 1-3. The level of the ankle sprain is determined by the amount that the ligament is torn or stretched. A grade one sprain is categorized as a slight stretching and damage to the fibers of the ligament. A grade 2 sprain is characterized as partial tearing of the ligament and abnormal laxity of the ankle. A grade 3 sprain is characterized by complete tear of the ligament if it can be pushed or pulled in certain movements there is gross instability. The movements of the ankle are abduction, adduction, plantar flexion, dorsiflexion, and inversion, eversion. The ligaments of the ankle hold the ankle bones and joint into position. These ligaments protect the ankle joint from abnormal movements such as twisting, turning, and rolling of the foot.
Therapeutic stretches of the gastrocnemius and soleus muscles. If the ligament are weakened, cross fiber friction them to try to regain some of the integrity of the ankle back.
ACL Injuries in Athletes The Anterior Cruciate Ligament (ACL) attaches the femur, which is the thighbone, and the tibia, which is the shin, together (northstar). A torn ACL is one of the most excruciating experiences in an athlete’s life. It is the first thing that comes to mind when they hurt their knee on the field; for many it is their greatest fear. A torn ACL can sometimes mean the end of an athlete’s career.
Muscle is a very specialized tissue that has both the ability to contract and the ability to conduct electrical impulses. Muscle fiber generates tension through the action of actin and myosin cross-bridge cycling. The muscle may shorten, lengthen or remain the same under tension. Skeletal muscle has an impressive ability to regenerate itself, which it does on a daily basis as well as in response to injury [1].
“The hamstrings are a collection of three muscles located in the back of the thigh that are responsible for bending, or flexing, the knee.” (emedicinehealth.com) the three muscles that make the hamstring are the semitendinosus, the semimembranosus, and the biceps femoris.
Kids just want to have fun. In a bygone era, parents wanted kids to play sports for fun and camaraderie. However, a new attitude is developing among coaches and parents, which is mopping-up fun from youth sports. Now it's all about the team and the game. The team must win the game at any cost.

Repair after a muscle is damaged happens through the division of certain cells who then fuse to existing, undamaged muscle fibers to correct the damage. Different muscle types take different amounts of time to heal and regenerate after it has been damaged. Smooth muscle cells can regenerate with the greatest capacity due to their ability to divide and create many more cells to help out. While cardiac muscle cells hardly regenerate at all due to the lack of specialized cells that aid in repair and regeneration. In skeletal muscle, satellite cells aid in helping restoration after injury. Along with muscles, tendons are very important structures within the human body, and they to can be damaged. However, tendon repair involves fibroblast cells cross-linking collagen fibers that aid in not only reinforcing structural support, but also mechanical support as well (“Understanding Tendon Injury,” 2005). While quite different from muscle repair, tendon repair involves the similarity of reestablishing d...
Ligaments are tough, non-stretchable fibers that hold bones together. Damage to cruciate ligaments, which crisscross the knee to give it stability, is one of the most common sports injuries. The “tear” occurs from changing direction rapidly, slowing down from running, or landing from a jump improperly. The A.C.L tear is one injury that worries athletes in all sports at all levels because of its devastating effects. People ages 15-25 that participate in basketball and other sports that require pivoting are especially at risk.
When owning a horse, you run into the problem of your horse getting injured. Getting the call from your barn manager or a friend saying that your horse is lame isn’t a call any horse owner wants to get, but is undoubtedly a call that everyone gets. The first thing that runs through their head is what happened? One of the scenarios that will enter a horse owner’s head will be a tendon, ligament, or joint injury. Many owners work very hard to prevent such injuries by feeding joint supplements, but owners can’t prevent the unexpected. Some of the major treatments out in the equine industry are even common in human tendon injuries, such as tendon splitting, stem cell therapy, and platelet rich plasma therapy. There are also several medicinal injections that have come available to veterinarians such as: Tildren, Adquan, and Legend. Every horse owner should have some knowledge of the above treatments, in order to provide the best therapy and healing for their horse.
There are many injuries in general, but sports injuries? Sprains and Strains are the most common injuries in sports. “Sprains are injuries to ligaments, the tough bands connecting in a joint. Suddenly stretching ligaments past their limits deforms or tears them” (Hoffman 1). Ligaments are like springs in a sense that when you stretch a spring, it will return to it’s normal state unless they are
The solution to this problem is located in the lab. Researchers across the country are working day in and day out to come up with a solution to accelerate the healing of soft tissues. They have come up with many solutions, from vibration therapy, to personalized rehab plans, but none of these are yielding truly significant results. I believe the solution lies at the molecular level. I believe that we can observe the healing of these soft connective tissues and learn from it. Then we can design a method from the observations to accelerate the production of the fibrils and collagen that will go on to make up the soft connective tissue. I have begun to take the beginning steps in solving this problem through my mentorship with Dr. Weinhold. Our research goals go hand in hand, which has led us to beginning research on the release of an angiogenic growth factor through a gelatin that will coat sutures. In theory, this angiogenic growth factor, once released from the crosslinking with the gelatin will stimulate the development of blood vessels around the recently repaired collagenous tissue. This, in turn, will allow the tendon/ligament to have a better oxygen supply and allow for quicker
The nerves are raging, mainly in his stomach as the butterflies flutter till no end. "Is everything ok? Will everything go as planned?" He couldn't stop thinking about what might happen. Images were racing wild as he thought about his teammates going to battle without him. He couldn't comprehend why he had to let them handle it on their own. He has played with them since they were in eighth grade, and when they need him the most, all he can do is sit and cheer. He hates this feeling of helplessness, but at the same time he knows he has to do what little he can do, well.
