8 Health Myths That Drive Consultants Loopy


When executed proper, train is usually a veritable miracle drug. However comply with the flawed recommendation and you’ll simply set your self up for harm. Take the sit-up: As soon as thought of the gold customary of core workout routines, we now know that it could make low-back ache worse.

Health tradition is rife with such misconceptions, due to continuously evolving science and health influencers who share ideas based mostly on “anecdote and gymnasium lore,” mentioned Brad Schoenfeld, a professor of train science at Lehman School in New York. “As soon as these opinions are disseminated to the general public and take maintain, they’re laborious to vary.”

I requested greater than a dozen health specialists to share the myths they hear most frequently amongst their shoppers and sufferers, and that they need they may debunk as soon as and for all.

In case you’ve taken a highschool gymnasium class, you’ve most likely been advised to spend a couple of minutes stretching earlier than exercising. However latest analysis has discovered that stretching earlier than exercising is ineffective for stopping harm and may very well work towards you. That’s as a result of stretching a muscle for greater than 90 seconds quickly diminishes its power.

“You’ve simply transiently weakened all of the muscle teams you’re making an attempt to coach,” mentioned Dr. Josh Goldman, affiliate director of the Heart for Sports activities Medication at UCLA Well being.

In case you actually benefit from the feeling of stretching earlier than bodily exercise, don’t maintain the stretch for lengthy, Dr. Goldman mentioned.

For the simplest preparation to work out, attempt a dynamic warm-up — a collection of energetic workout routines that get your blood flowing and gently stress your muscle groups. Save your stretching for a separate time, he mentioned. “I like to inform individuals to do it earlier than mattress,” because it offers your muscle groups time to get well earlier than transferring once more.

Not true, mentioned Dr. Schoenfeld, who research muscle development. A big physique of analysis now exhibits that lifting comparatively gentle weights for, say, 30 repetitions is simply as efficient at constructing muscle and power as lifting weights that really feel heavier for 5 to 12 reps. It’s a matter of non-public choice.

However don’t keep away from heavy weights for concern that they’ll make you “bulk up,” mentioned Dr. Jacob Sellon, a sports activities medication doctor on the Mayo Clinic. “It really takes plenty of effort” to construct Popeye muscle groups, he mentioned. “It doesn’t simply occur with typical power coaching.”

Worry not, analysis has debunked the notion that operating will increase your threat of osteoarthritis, and even suggests it might probably shield your knees towards the situation. The truth is, not transferring will increase your threat of creating osteoarthritis, together with age, weight and genetics.

For years, specialists thought that “our knees had been like tires — you drive the automobile lots, you burn by way of your tire tread,” Dr. Goldman mentioned. “That’s not true, as a result of our physique is dynamic,” and our joints can regenerate themselves, particularly after we are frequently energetic.

That mentioned, operating can undoubtedly result in knee ache or harm in case you prepare too aggressively, mentioned Dr. Jordan Metzl, a sports activities medication doctor on the Hospital for Particular Surgical procedure in New York. Dr. Metzl referred to as this “violating the rule of toos” — operating too quick or too far too quickly. “Improve slowly,” he mentioned. And in case you begin to really feel knee ache, get it checked out as quickly as doable by a sports activities medication skilled.

Strolling is widespread amongst older People for good purpose: It’s been proven to decrease the chance of coronary heart illness, diabetes and sure cancers, in addition to the threat of untimely dying. And it’s so doable.

However strolling by itself is not sufficient to remain match as you become old, mentioned Anne Brady, an affiliate professor of train science on the College of North Carolina-Greensboro. Beginning in your 30s, your muscle mass progressively declines, she mentioned, so that you additionally must give attention to power coaching.

“Individuals can do day by day actions with a minimal quantity of cardiovascular health,” she mentioned. “However after they don’t have the power or the muscle energy to do day by day actions, that’s after they lose their independence.”

Complement walks with at the very least two 20-minute strength-training classes each week.

Selecting to do a less-strenuous model of an train — say, a push-up or plank along with your knees on the bottom — doesn’t imply you’re weak or a novice or that you just’re backsliding, mentioned Stephanie Roth-Goldberg, a scientific social employee and therapist in New York who works with athletes. It’s an indication that you just’re listening to your physique and holding it protected.

“Our our bodies require various things on completely different days,” she mentioned. “Modifying workout routines helps us work on type and the mind-body connection.”

Amanda Katz, an authorized power and operating coach in New York Metropolis, mentioned she usually has to persuade shoppers who run or cycle that additionally they wanted to strength-train their decrease physique.

Pounding the pavement or pushing pedals does strengthen your decrease physique, however not sufficient to stimulate important muscle development, she mentioned. A strength-training routine that features squats, lunges, glute bridges and pointers can enhance bone density and decrease your threat of harm — and make you a stronger runner or bike owner, too.

Nope. Train scientists debunked this one years in the past, however many People nonetheless see it as a benchmark of fine well being, mentioned Cedric Bryant, the president and chief science officer of the American Council on Train

The parable traces again to the Nineteen Sixties, when a Japanese clock producer mass-produced a pedometer with a reputation that translated to “10,000-steps meter.” “Sadly, it’s taken on a lifetime of its personal, as a result of the analysis clearly doesn’t assist there being something magical about that purpose,” Dr. Bryant mentioned.

The newest analysis means that the well being advantages of strolling seem to plateau at round 7,500 steps, however at the same time as few as 4,000 steps per day can cut back the chance of dying from any trigger.

Plunging into an icy tub after a troublesome exercise can really feel like a safeguard towards harm, because it helps to scale back irritation. However there’s an issue with this.

“Not all irritation is dangerous irritation,” Dr. Goldman mentioned. In case you leap into an ice tub after each exercise, you sluggish or cease the restore course of.

Once you work out, you create helpful irritation by strategically stressing your muscle groups, and because the physique heals, it builds power, he mentioned. If you wish to are inclined to a selected harm after a exercise, Dr. Goldman really useful both icing the harm itself or ready a day earlier than taking a chilly dip, to present your muscle groups time to begin the restore course of.

The identical rule applies to over-the-counter ache drugs like NSAIDs: As a result of they’re anti-inflammatory, you need to solely take them after a exercise in case you’re treating an harm. In any other case, you threat counteracting your coaching.

“Chilly water immersion is an excellent anti-inflammatory device, however you’ve received to make use of it in a time the place you really wish to stop irritation and never as a prescription after each exercise,” Dr. Goldman mentioned.

For general restoration after a exercise, analysis suggests saunas could also be safer and more practical.
