💪🌱 La potencia muscular también se cultiva desde la infancia. Prevenir la “powerpenia pediátrica” con juego activo, saltos, carreras y fuerza adaptada ayuda a crear una reserva física que puede proteger la función muscular durante toda la vida 🧒🏃‍♀️🏃‍♂️👟 bjsm.bmj.com/content/early/…

I’ve been an orthopedic surgeon for nearly 30 years, and a few patterns have become impossible to ignore. One is that many musculoskeletal problems in adults aren’t sudden injuries. They’re the moment when declining capacity and awful metabolic health finally reveals itself. Over the decades your strength fades, muscle mass declines, as your aerobic capacity tanks. Tendons and connective tissues lose substance, stiffness, and resilience. For years the body compensated... quietly. Then one day a knee hurts during a run to get the train, or shoulder aches reaching overhead, or a back tightens lifting something simple. At that point the story usually becomes more about structural damage. An MRI gets ordered. Welcome to high-tech, low-medicine. And the MRI almost always finds something. A meniscus tear. A rotator cuff tear. A disc bulge. Why? Because by midlife these findings are extremely common — even in people with no pain at all. If you have a tear in one shoulder, image the other shoulder... you probably have the same tear there. But I digress. Once the scan appears, the narrative changes. The image becomes the diagnosis. Now the patient believes something is broken, and the focus often shifts to fixing what the MRI shows. What often gets lost in this is the reason the symptoms appeared in the first place. Many so-called “atraumatic” orthopedic complaints are not purely mechanical failures. They are the moment when reduced strength, declining tissue capacity, and sometimes broader metabolic health issues finally reach a tipping point. Our tissues change over the decades... get over it. In other words, the MRI didn’t create the problem. Well... it sort of did in this scenario. But all the MRI showed was something that was already there.... because of your age, lifestyle, health and so on. The real driver of symptoms is often loss of physiologic reserve. Less muscle. Less tendon or aerobic resilience. Less tolerance for load, etc. Once the MRI enters the picture, the risk becomes overtreatment. This is probably the number one reason people have surgery. When in many cases the most powerful intervention was never the scan or the procedure. It was rebuilding capacity. Strong muscles stabilize joints. Aerobic fitness improves metabolic health and tissue perfusion. Gradual loading restores tolerance. But people often don't take PT seriously prior to surgery. They often take PT very seriously afterwards. Therefore, PT is probably the reason you feel better, despite the surgery. The irony is that the treatment many people ultimately need is the same thing that might have prevented the problem in the first place. Staying strong. Staying active. Maintaining the reserve that protects our joints/tendons/muscles/abilities as we age.

Telling kids to sit still doesn’t build discipline. It stifles imagination. Evidence: When students are given freedom to fidget and wiggle in their seats, they pay just as much attention—and generate more creative ideas. Physical activity unlocks mental agility.

For about a decade, I’ve been showing these two slides at conferences. Two hunter-gatherer populations (Hadza and Tsimane), likely the closest living humans to our Paleolithic ancestors. Diet: • 65–70% carbohydrates • 15-20% protein • 10–15% fat • ~13% lower daily caloric intake than the US population Daily movement: • 115–135 minutes per day • 6–12 km of walking Health outcomes: • Obesity: ~2% • Type 2 diabetes: ~1% • Cardiovascular disease: among the lowest ever observed This is not a low-carbohydrate population. The difference is metabolic fitness. When mitochondria are continuously stimulated by daily movement, carbohydrates can be oxidized (burnt). When movement disappears, fuel oxidation fails and metabolic disease emerges. The debate should not be low-carb vs high-carb. That debate has failed to solve obesity or type 2 diabetes for decades. The real question is: Can your mitochondria still do their job? #MitochondrialFunction #MetabolicFitness #MetabolicFlexibility #PhysicalActivity

Lifting weights reverses muscle aging.

Exercise is an antidepressant. A new meta-analysis of 26 randomized controlled studies found that both aerobic and resistance training significantly reduced symptoms of depression and anxiety, often rivaling standard treatments like medication and therapy. Although both modes were beneficial, aerobic exercise had a slightly greater impact on depression, while resistance training showed a modest edge for anxiety. Many of the included studies didn't even meet the minimum weekly physical activity recommendations for aerobic or resistance exercise, and even then, reduced depressive and anxiety symptoms significantly. For those with depression or anxiety, movement is powerful medicine. And the dose needed might be smaller than you think.
