It is risky.
Stay fresh. Avoid repeating yourself. Don’t rant. Never preach. These would be the ‘rules’ of supposedly good blogs.
And, of course, doctors that dare to take a stance on health issues risk being perceived as pretentious. I get this.
So it is with trepidation that I write a follow-up to last week’s CW post about right ventricular damage immediately after an extreme race effort. Notwithstanding the pompousness concern, I also wish to avoid being labeled anti-exercise. Few believe more strongly in the healing powers of exercise.
But last Wednesday’s comments (both on the blog, Facebook and here on Dr. Val Jones’ BetterHealth blog) were just too good to let rest.
On the assessment of studies: Read more »

When you sit quietly, your heart slips into the slower, steady pace known as your resting heart rate. A new study suggests that an increase in this rate over time may be a signal of heart trouble ahead.
Your heart rate changes from minute to minute. It depends on whether you are standing up or lying down, moving around or sitting still, stressed or relaxed. Your resting heart rate, though, tends to be stable from day to day. The usual range for resting heart rate is anywhere between 60 and 90 beats per minute. Above 90 is considered high.
Many factors influence resting heart rate. Genes play a role. Aging tends to speed it up. Regular exercise tends to slow it down. (In his prime, champion cyclist Lance Armstrong had a resting heart rate of just 32 beats per minute.) Stress, medications, and medical conditions also influence the heart rate.
In today’s Journal of the American Medical Association, researchers from Norway report Read more »

Severe osteoarthritis of the hands
One of my patients came to see me today with severe right knee pain. This is not a new problem, and in fact, we have been dealing with flare ups of her osteoarthritis for years. It mainly affects her knees and hands and today her right knee was swollen and felt like the “bone was rubbing together” with each step. She could hardly walk because of the pain.
Osteoarthritis is also known as degenerative arthritis and it is one of the most common maladies of aging joints, affecting millions of people. The cartilage in joints wears down and inflammation causes the bones to build up spurs and small micro tears. It affects women more than men and the cause is unknown. There are likely genetic factors as it tends to run in families. Arthritis can occur in any joint but the most common are the fingers, wrists, hips, neck and spine and knees. Stiffness (especially in the morning) and pain are the main symptoms that limit mobility.

Dear Endurance Athletes,
Accept an apology in advance. You have endured so much from me.
Sorry.
Let’s at least start by agreeing that I can’t control the data.
Yes, you guessed it. There is unfortunately more bad news pertaining to the deleterious effects of endurance exercise on the human heart.
Again, I am sorry. Maybe re-phrasing the previous sentence will soften the blow. How about this: “Yet another study on endurance athletes suggests that exercise, like everything else in life, has an upper limit.”
Here goes, buckle up. Read more »

Do your neck and shoulders ache? Not long ago, you would have been told to rest, maybe use a neck brace, and wait until the pain had ebbed away. Doctors have changed their song about the best treatment for neck and shoulder pain. They now recommend movement instead of rest.
As described in Neck and Shoulder Pain, a newly updated Special Health Report from Harvard Health Publications, there is mounting scientific evidence for the role of stretching and muscle strengthening in treating people with neck and shoulder pain. After a whiplash injury, for example, people heal sooner and are less likely to develop chronic pain if they start gentle exercise as soon as possible. For those with long-term pain (called chronic pain), results from controlled studies show that exercise provides some relief.
One review of the research found that Read more »
