"Doctors have known for some time that strengthening your quadriceps – the strong muscles at the front of your thigh – can help ease the pain of arthritic knees. Now research shows that the medications you take to ease arthritis pain can help you strengthen your quadriceps.
In research conducted at Ball State University's Human Performance Laboratory, in Muncie, Ind., 36 men and women between the ages of 60 and 78 were randomly assigned to take standard daily dosages – comparable to that which people with chronic arthritis pain might take – of either ibuprofen or acetaminophen or a placebo. The particpants then went to work in the lab, doing 15- to 20-minute weight training sessions three times a week for three months.
While all of the particpants experienced improvements in quadriceps muscle mass and strength over the three-month course of the study, magnetic resonance imaging (MRI) showed that the increase of muscle mass in the ibuprofen and acetaminophen users was significantly greater.
Building strength has built steam as a great way to help people with arthritis function better and relieve soreness, stiffness and pain. Arthritis Today recently reported on a study from Great Britain showing that strength-training may improve physical function in people with mildly disabling, well-controlled RA.
Interestingly, an earlier study by researchers at the same lab showed a negative effect of ibuprofen and acetaminophen on muscle over a 24-hour period. Longer-term, however, regular use of ibuprofen or acetaminophen during strength training appears to have induced intramuscular changes that enhance the metabolic response to resistance exercise, allowing the body to add substantially more new protein to muscle, says Todd Trappe, PhD, associate professor of physical education at Ball State.
The researchers are now testing muscle biopsies taken before and after the three-month strength-training program in order to understand for the drugs’ positive long-term effect on muscle mass.
It should be noted that taking more than one anti-inflammatory med at a time may be harmful to your heatlh."
So I guess YOU ARE WRONG
