What Happens To Arm Muscle Fiber After Being In A Cast
Out of cast after 4 weeks (long arm) muscles in forearm tight n painful n numbness in thumb normal post cast? I had epychondolitis n torn tendon
Can be expected --:
Stiffness from being in a cast for 4 weeks. Numbness maybe from cast being too tight or the cotton padding may have bunched up causing a local neuritis, which should clear up in 2-3 weeks time. As you exercise the tight muscles should loosen up and get stronger, reducing the stiffness as well.
Massage/stretching exercises would help the epicondylitis. The doc should advise re: the torn tendon! ...Read more
It is a body tissue that has the ability to contract. It shortens and generates force. It relaxes and returns to its original length. Muscles move joints, stabilize the body, move air and food through the organs, act as valves for bladder, bowel and other organs. They control movement of the eyes. They help us express ourselves by changing the shape of our ...Read more
Out of cast after 4wks (long arm) forearm muscles tight n painful n numb thumb. Normal after casting? Have epychondolitis n partial tendon tear
I fell and had my forearm bruised for 2 weeks. Now there is a 1/2 golfball of hard mass with a weird muscle like feeling fibers on one side. No pain?
Bump: Likely a hematoma or collection of old blood. Should slowly resolve over a few weeks. If doesn't, go see an MD to confirm diagnosis. ...Read more
No.: No, the muscles will return to normal size as you begin to use your arm and hand again. ...Read more
What other diseases/conditions are associated with "COX negative fibers on muscle biopsy" besides mitochondrial diseases?
Complex issues. Best: Look them up yourself. E.g. https://www. Google. Com/search? Q=muscle+biopsy+COX+negative+fibers, https://scholar. Google. Com/scholar? Q=muscle+biopsy+COX+negative+fibers & http://emedicine. Medscape. Com/article/1847877-overview would be good places to begin. ...Read more
Muscle fibers forming pacemaker are less striated than other muscle fibers. But does it help the pacemaker conduct impulse faster, how?
Not clear?: No muscle fibers make the pacemaker. Pacemaker is an artificial device implanted in one's heart. The leas of a pacemaker are not in the muscle but in one of the heart vessels. ...Read more
Why is it said that to build more muscles you have to lift heavier by activating fast twitch fibers? I only get the pump with light weights.
Strength: Fast twitch fibers are involved with strength, slow twitch with endurance, so the former tend to grow in size and volume. ...Read more
It seems like I have a handing muscle fiber in the upper part of my anus, which is creates kinda like a bridge (covered by skin) between two sides. This area often get inflamed. What should I do?
Pilomoidal: It could be a cyst have a doctor look at it imay get infected or need to be removed if troublesome ...Read more
Not sure.: Not sure what you mean. Your blood is the concentration it is. And it is that way for good reason. It is optimized. You really can't change concentration unless you really dehydrate yourself or get a transfusion a la lance armstrong blood doping. ...Read more
Strength Training: Low rep, high resistance strength training will build more type I fast twitch fibers. These types of muscle fibers will be very effective for activities requiring bursts of power. ...Read more
See below: The heart is a muscle with very special qualities. The main bulk of heart muscle helps pump blood to the lungs to get oxygen and then pumps that oxygen rich blood to the rest of the body. Then there is a special type of cardiac fibers that helps conduct electrical impulses from two "pacemaker" sites in the heart, the sa and av nodes which allow the heart to keep pumping for your entire life. ...Read more
Yes and no: I would recommend you focus on one goal of either losing weight or gaining muscle. It is hard to chase two opposing targets at the same time. For gaining muscle you need to be on calorie surplus and for losing weight you need to be on calorie deficit. Set one goal to lose weight once you achieve it go for the second goal of gaining muscle mass. ...Read more
Had critical illness polymyopathy from status asthmaticus...Now emg normal could I have type 2 muscle fiber damage and that's why normal emg?
How do you FEEL?: The best way to tell how well you have recovered from this complicated illness is by how you feel. Since long-term there's no specific treatment and conditioning is important, you are the one to answer the question. And you're right -- a normal EMG does not rule anything in or out. Hope it's a good recovery, best of luck. ...Read more
How does your aorta respond differently to mental stress and physical stress? Doesn't the muscle fibers respond differently in different situations?
What is "rare atrophic muscle fibers in a bkgrnd with non specific changes"? Is it positive for a neuromuscular disorder? Symp's, all over musle pain.
Atrophic fiber: If it is a specific for diagnosis of NMD, it is reported as diagnostic/suggestive/confirmatory etc. That's probably a nonspecific (not suggestive of NMD) finding. If you have concerns, you may talk to the pathologist who reported it. ...Read more
Type 1 and 2: All skeletal muscle has a mixture of type 1 (slow twitch) and type 2 (fast twitch) muscle fibers, including the psoas. ...Read more
Would taking supplements for mitochondria help slow twitch muscle fibers, and what do fast twitch fibers have to be able to work without mitochondria?
For mitochondria?: Please repost your question & include which supplements you mean, how they are supposed to work to "help mitochondria, " why you think your mitochondria need a supplement, and what you expect to achieve with supplements. This sounds as bogus as a $3 bill. You have to be a skeptic about these things. If you're not a skeptic, you'll be a sucker. ...Read more
Among the following, which is smallest. Muscle fiber, thick filament, or myofibril? Which is largest?
Does working out increase the size or the amount of muscle fibers? Also, is there a way to increase the actual number of fast twitch muscle fibers?
Muscle strengthening: We are born with fixed amount if muscle. Exercise increases the fiber size, but does. It add more fibers per se. Focused strengthening will reduce fat in muscle and improve the efficiency of contractions. I question if the fiber mix will change but there will significant improvement in performance like, this, so result will be the same. PT or exercise trainers can assist here. ...Read more
I felt things pull from neck and back and now I have a very fibrous feeling in neck and back. Can I be feeling the muscle fibers of torn muscles or li?
Muscle fibers: Muscles fibers are correct they "lock" up when not stretched properly and can cause significant neck pain along with decreased range of motion. Warm compresses and stretching should help. In extreme instances I have done trigger point injections, but very rarely. Hope this helps. Dr d. ...Read more
No: The effects of muscle stretching are different than resistance training. Both are important. Stretching, particularly after you are warmed up helps balance the muscles from the front of the body with the muscles in the back of the body. This is important to avoid injury and help your joints work with less stress. Resistance training will build muscle strength by inducing muscles to enlarge. ...Read more
Do certain muscles have a greater portion of certain muscle fiber types over other ones? Like do hamstrings contain more type II or type I fibers
Depends on training:
Muscles involved in endurance activities typically have more type ii slow twitch fibers, however depending on how one trains, the balance between type I and type ii fibers changes.
Endurance building workouts and training will generate hypertrophy in the slow twitch type ii fibers, while pure strength building workout tends ot build more type I muscle tissue. ...Read more
Achilles tendonitis- stretching pulls muscle fibers away from each other, making healing process longer. Do you agree? Healing advice? How long?
Rest and immobilizat: It may take a long time to heal achilles tendonitis because of the poor blood supply to the achilles tendon. Therefore rest, immobilization, shioes with heel lift, such as running shoes, orthoses to relieve stress on the achilles tendon and gentle stretching as well as ice and massage of the tendon are all good treatments. We also use physical therapy from a sports pt. ...Read more
