At least he’s trying…
Yet another good article from Gretchen Reynolds at NYT:
“Lifting weights might also lift moods, according to an important new review of dozens of studies about strength training and depression. It finds that resistance exercise often substantially reduces people’s gloom, no matter how melancholy they feel at first, or how often — or seldom — they actually get to the gym and lift.
There already is considerable evidence that exercise, in general, can help to both stave off and treat depression. A large-scale 2016 review that involved more than a million people, for instance, concluded that being physically fit substantially reduces the risk that someone will develop clinical depression. Other studies and reviews have found that exercise also can reduce symptoms of depression in people who have been given diagnoses of the condition.
But most of these past studies and reviews have focused on aerobic exercise, such as walking or jogging. Far less has been known about the possible benefits, if any, of strength training for mental health. One 2017 analysis of past research had found that strength training can help people feel less anxious and nervous.”
I’m not surprised.
“Resistance exercise training significantly reduced depressive symptoms among adults regardless of health status, total prescribed volume of resistance exercise training, or significant improvements in strength.”

Not that serious…yet
Seriously athletic folks, particularly those in sports with high aerobic demand, should avoid these BP drug classes:
- Diuretics (they predispose to dehydration)
- Beta blockers (they may decrease exercise tolerance via slowing of heart rate)
Better choices for athletes are:
- Angiotensin converting enzyme inhibitors (ACEIs)
- Angiotensin II receptor blockers (ARBs)
- long-acting dihydropyridine calcium channel blockers
These latter drugs are not likely to affect athletic performance or cause other complications. If you can’t figure out which class of drug you take, ask your physician or pharmacist.

From The New York Times:
It is a question that plagues all who struggle with weight: Why do some of us manage to keep off lost pounds, while others regain them?
Now, a study of 14 participants from the “Biggest Loser” television show provides an answer: physical activity — and much more of it than public health guidelines suggest.
On average, those who managed to maintain a significant weight loss had 80 minutes a day of moderate activity, like walking, or 35 minutes a day of vigorous exercise, like running.
My patients taught me this lesson years ago.
She’ll lose muscle fibers if she gets too sedentary as she ages
“Our lab and others have shown repeatedly that older muscles will grow and strengthen,” says Marcas Bamman, a professor of integrative biology at the University of Alabama at Birmingham. In his studies, men and women in their 60s and 70s who began supervised weight training developed muscles that were as large and strong as those of your average 40-year-old.”

Dr. Bamman says older folks (over 60?) don’t add new muscle fibers like young’uns do. But an effective exercise program will cause hypertrophy (growth) of the existing muscle fibers. “Effectiveness” probably depends on exhausting muscle groups during weigh training.
Of course, he’s right. Click the link below for his reasons.
“Strength – as well as a tolerance for childish nonsense – is the thing we all lose as we age. Squatting down, standing back up, putting things overhead, pulling things up the driveway, loading the groceries, wrestling with the grandkids, teaching the dog who’s boss, mowing the yard, putting the broken lawnmower in the truck again: simple physical tasks we took for granted years ago are often problems for older, weaker people, as well as a source of potential injury that can be expensive and debilitating.
For most of us, this happens because of inactivity. If you do not use your muscles to produce enough force to convince them to maintain their ability to do so, it shouldn’t be surprising that they become less capable of doing it. And walking, running, riding a bicycle – physical activities whose performance is not limited by strength for even moderately active people – cannot increase or even maintain strength.”

From a recent meta-analysis:
“In conclusion, there is no evidence that currently available interventions are able to increase physical activity among overweight or obese children. This questions the contribution of physical activity to the treatment of overweight and obesity in children in the studied interventions and calls for other treatment strategies.”

For weight loss in overweight and obese children, you have to focus on diet modification. Same as adults.
