Scusate se insisto ragazzi...Quindi nessuno sa nulla su determinati integratori o esercizi che potrebbero prevenire problemi di infiammazione ai tendini?
Not much scientific research has been done to investigate the effects of specific nutritional supplements on the healing of tendinosis. Basic good nutrition is advisable though because it gives your body the best chance to heal.
Ascorbic acid (vitamin C) stimulates Type I collagen synthesis when used in cultures of healthy fibroblast cells. However, when ascorbic acid was added to cells from carpal tunnel syndrome patients, it did not stimulate the normal amount of Type I collagen, and the small amount of Type I collagen that was produced had an abnormally high alpha2(I) to alpha1(I) ratio.[1] Adding vitamin C to the injured cells simply made them produce more abnormal collagen, not normal collagen.
Although glucosamine sulfate and chondroitin sulfate can be very helpful for osteoarthritis, they are not likely to help tendinosis. Based on the comments I've seen online, most people who have tried glucosamine for tendinosis haven't noticed any improvement. This is not surprising because tendinosis and osteoarthritis are quite different. Osteoarthritis causes a decrease in collagen, proteoglycans, and glycosaminoglycans (GAGs) in cartilage. Tendinosis causes a decrease in collagen in the injured tendon, but it actually causes an increase in proteoglycans and GAGs, such as chondroitin sulfate and hyaluronan.[7,8,13,18,40] Gluscosamine sulfate and chondroitin sulfate help build proteoglycans; since the levels of GAGs and proteoglycans are already abnormally high in tendinosis, you wouldn't expect oral supplementation of glucosamine and chondroitin to help.
Some supplements are sold with the claim that they will raise growth hormone levels and therefore help heal all sorts of problems, including chronic tendon injuries. Even if these supplements could raise growth hormone levels (which is unproven), the higher growth hormone might just stimulate more abnormal collagen rather than normal collagen (since that was the effect of adding growth factors to cells from carpal tunnel syndrome patients).[1]
Other supplements that claim to help heal tendons and ligaments contain the amino acids glycine, lysine, and proline. This idea seems logical since those three amino acids are very abundant in tendon and ligament collagen. However, the problem again is that merely throwing more collagen ingredients at the injured tenocyte cells probably won't change their behavior of making abnormal collagen. You should be sure to get enough protein in your diet so you're not outright deficient in amino acids, but there's no evidence to suggest that extra amino acids can cure tendinosis.
Maybe someday we'll find a tendinosis-specific supplement that can somehow induce the injured cells in tendinosis to make normal collagen, but for now we don't know of anything. Your best bet is to eat a healthy diet with plenty of fruits, vegetables, good fats, protein, whole grains, and antioxidants and with minimal amounts of trans fats, saturated fats, and simple carbohydrates.

Although we don't know of a supplement that can help the collagen in tendinosis injuries heal, we do know of some supplements that can help inflammation. Tendinosis is not an inflammatory injury, but if you have an acute sprain/strain or an acute flare-up involving inflammation, some of these supplements might help, and eating an ant-inflammatory diet has been found to be good for your general health. The following are some of the supplements that have been found to be anti-inflammatory in arthritis patients: ginger, tumeric, boswellia, bromelain, and fish oil.
