How does age affect your sport performance?
I am not an athlete, but I am in my 50s, so I have a bit of insight on the effects of age on performance in general. As you get older, your metabolism slows, regardless of your diet or activity level. It becomes harder to gain/maintain muscle mass. You may lose strength regardless of how much you increase your exercise efforts, compared to your previous strength levels. For example, you may still be able to bench press the same weight, but it will become more difficult, or you may find that you need to decrease the weight in order to do a bench press.Because of the lessening of muscle density, you will probably also find that even with visible muscle mass, there will be areas on your body where skin is loose rather than taut over the muscles. Partly because of the loss of muscle support and partly because of age-related degeneration, you are also at higher risk of injury to your joints. Both bones and cartilage become weaker, and an activity that you participated in for years without more than a bit of muscle soreness later might suddenly send you to a doctor and/or a physical therapist because you stressed a weakened joint.Naturally, as your strength decreases, your speed and agility are going to lessen as well. Adding to that, age also affects your vision and hearing, and if those are vital for your sport, your performance will be affected. Some people begin to have problems with balance because of effects of hearing loss (did you know that many balance problems originate in the inner ear?) or from changes in the brain. None of these changes are the same in all people. There is no guaranteed, linear progression of age-related losses. Genetics plays a huge role. Whether or not you injure yourself makes a big difference, because not only will the healed injury be likely to recur, but also because it might keep you from participating in the sport or even exercising at all. Remaining active (without hurting yourself) may delay some of the muscle loss (and strengthen bones - but not cartilage) but could strain ligaments/tendons. Sometimes the ageing process will force you to give up a particular sport, but you may have the option of taking up a different activity that's more suitable for your abilities/limitations. The worst thing you can do as you get older is pretend that you can still do all the things you used to be able to do when you were younger!
Will Knee Cartilage Loss Affect My Ability To Play Sports?
It depends on your work ethic. My best advice for you is to work hard and perform very well in practice every day. In addition, what you need to do this (and every) summer is eat healthy, exercise by doing weight lifting, and either jogging or going for a long run every day. If you do these things, you will get faster, stronger, and into better shape, which will greatly improve your chances of becoming a successful, top notch offensive lineman in football, as well as overcoming your knee cartilage loss. By the way, your chances of playing college football depend on your performance in football during your high school career, especially during your senior year of high school. If you perform very well in football during your high school years, you will greatly improve your chances of getting recruited to play for a college football program. In turn, your chances of playing in the NFL depend on your performance in football during your college football career. If you perform very well in football during your college years, you will greatly improve your chances of getting drafted to play for an NFL team in the future.
Can sports injuries cause arthritis?
That old football injury may have healed long ago, but the post-trauma damage can last a lifetime.You may not remember the time you twisted your ankle while playing football in high school, but your body does. A study has found that post-traumatic arthritis, a type of osteoarthritis, is a leading cause of joint disability. This chronic disease is caused by injury and wear and tear of the joints, and it affects 23 percent of adults nationwide.When an injury affects a joint, it may heal completely but develop arthritis, sometimes decades later. One way to tell if you have post-traumatic arthritis is if the arthritis occurs in only one joint. Another clue is if arthritis occurs at a younger age. Typically, osteoarthritis usually develops in people who are 60 or older.Common sports injuries that can trigger post-traumatic arthritis include sprains, knee injuries, cartilage tears, fractures and dislocations. These can be acute injuries that occur suddenly or chronic injuries with nagging, ongoing pain.Reducing Arthritis PainWhile there is no cure for arthritis, the following are ways to minimize pain and maximize use of your joint:Use anti-inflammatory drugs such as aspirin or ibuprofen to reduce swelling and painRest the joint after repeated useStrengthen and improve the range of motion in the joint using weightsApply cold or heat packs as needed, or have massages to loosen stiffness in the jointYou can also slow the effects of arthritis by maintaining the appropriate weight for your size and exercising regularly. Avoid continual stress on your joints if possible.Cutting-Edge Arthritis Research at KeckThe doctors at the USC Department of Orthopaedic Surgery at Keck Medicine of USC are on the cutting edge of research to discover new osteoarthritis therapies that could significantly impact standards of care for the disease. Denis Evseenko, MD, PhD, associate professor of orthopaedic surgery, stem cell biology and regenerative medicine, is working to develop a cheaper, minimally invasive therapy that will reduce the need for joint replacement surgeries.“Bridging the gap between scientific innovation and clinical application is critical for our mission to provide the best quality of patient care,” said Jay Lieberman, MD, professor and chair of the Department of Orthopaedic Surgery at the Keck School of Medicine of USC.
Seiza's effect on the knees?
The position of seiza does fall within the normal range of motion for the knee joint. Although the position falls within range it can create compression of the cartilage and bursa of the knee. When we are not use to the position it initially can cause reduced circulation to the lower extremity, muscle cramping, and pain from "tight" tendons and ligaments depending on how long seiza is maintained. However, if we aren't moving from the knees, "knee-walking" if you will, the amount of damage shouldn't be all that severe even over a long periods of time. This is because the muscles, tendons, and ligaments should somewhat adapt to the position and reduce the overall stress to the joint, plus from seiza the body weight distributes across both the surfaces of the lower leg and thigh. The knees are not load bearing at this point. If we include "knee-walking", then my opinion is that the amount of cumulative damage increases. This is due to the joint being positioned into load-bearing in a manner it wasn't designed to handle over long periods of time. Add to that the torsion of the joint as the body pivots on the knees in place of the ball or heel of the foot.
Does masturbation affect your knees?
masturbation decreases your stamina. To keep up an erection is like trying to keep a light bulb on. + the ejaculation and the orgasm energy required. Regarding the keens, I think they are related as you hear cracks sometimes after you masturbate. I've red an article saying that the rapid decrease of hormones after the ejaculations affects the cartilage cells in your knees. When you do sex once a month or so it's ok, the damage is insignificant but when you do it everyday....
Can you play table tennis with injury in your knee?
If it isn't too bad, you can wear a knee brace and play. You will not be able to move as quickly as before, though. I wear a knee brace for sports and get by. Try it and see. If you have a ligament tear, you may need surgery.
What is the prognosis for a dislocated knee regarding any normal use for walking, running, or in sports?
There is very grave misconception about knee dislocation. Knee dislocation is a very serious catastrophic event that could lead to leg amputation. In a knee dislocation there is extensive damage to all structures in the joint including artiries and nerves. It is usually caused by a high energy trauma as in road traffics accident, jumping over a ditch with severe twisting of the knee and fall from a tall building. If the your knee survives you might be an invalid after all anyway. Therefore there could be any question about playing sports anymore.
