Is there a magical prescription for how much exercise and activity eliminates the increased risk of premature death, which comes from sedentary behavior? A new paper takes a swing at an elusive target. Spoiler alert: This is an area that continues to defy precision.
While we can "fix" a hip fracture, patients just are not as mobile and independent after the injury. And that's the case even after a year of recovery. One preventative measure may be Tai Chi, a martial art that teaches defense through balance, and working with -- rather than against -- forces.
Conventional wisdom tells us that 10,000 steps per day is the "magic number" required for health benefits. But is there sound evidence behind this number? Dr. Christopher Labos, from McGill University’s Office for Science and Society, investigates.
Aging can be associated with a loss of muscle mass and functional deficits. Recent research finds that while testosterone can help older men gain muscle, just adding more protein to the diet does not. Thus, there doesn't seem to be a reason to change protein requirements for seniors.
Good news: more of us are walking than we were even 10 years ago, and over 60 percent of both adult men and women report regular walking. That still leaves us with a large proportion of couch potatoes; certain demographic groups do lag behind. Perhaps the message that needs better targeting: even moderate activity can be beneficial.
One way to motivate people to exercise is for them to get a dog. After all, unless you live in the outback and let the animal run free, having a dog means walking it — except in a few circumstances. Australian investigators described the owner- and pup-associated reasons for a person to increase their walking level.  
An important question is what type of exercise — aerobic, such as walking, swimming or bike riding; or resistance, such as weight lifting — would help the older obese person who's looking to lose weight? The answer is both, particularly when done in tandem.
Emmy-winning TV anchor Ernie Anastos kicks off his new show with this "Doctors on Call" segment. Urologic oncologist Dr. David Samadi & Dr. Jamie Wells, our Director of Medicine, answer the public's questions.
Couch potatoes pay attention — you don't have to run miles each day to benefit your health. Indeed, recent research indicates that moderate levels of activity can significantly lower mortality risks.
So, how are your New Year's resolutions going? If you're like most who re-dedicated themselves to eating better and exercising more at the start of 2017, it's a safe bet the answer is "not so good." The reason, experts say, is that self-improvement promises immediately makes us feel good, but when it's time to keep them, negativity returns.
Ladies, if feeling older than you look appeals to you, take a seat while you read this: A recent study found that women who sit longer than 10 hours a day, combined with low physical activity, have cells that are biologically older — eight years older to be exact — than their actual age. 
Listen up, slackers: You can no longer use "work" as an excuse to avoid burning calories during the week. Turns out, you could get your best workout in over the weekend, without lifting a finger Monday through Friday.
