VO2 max predicts long-term mortality better than smoking, diabetes, or hypertension — yet almost nobody measures it. Here’s what it is, why the heart is the real bottleneck, and how the evidence says to train it. Ask most people about their health numbers and they’ll rattle off blood pressure, cholesterol, maybe resting heart rate. Almost…
Salah and Raphinha are the latest hamstring casualties of the 2026 World Cup. We break down why this injury dominates elite football, and what rehab and prevention actually work, according to the research. Halfway through the knockout rounds of the 2026 World Cup, the injury list is starting to look familiar. Mohamed Salah went off…
Cuando hablamos de “entrenar el core”, la mayoría de la gente piensa automáticamente en abdominales. Pero esa idea se queda muy corta. El core no es un músculo, ni siquiera un grupo de músculos con una única función: es una zona funcional completa que trabaja para frenar el movimiento, no para generarlo. Y esa diferencia…
Sitting for long periods physically changes how stiff your lumbar spine becomes. We explain why, with the science, and what movement reverses it. You don’t need to lift anything or move the wrong way for your lower back to start complaining. Sometimes just staying still is enough. If you work seated, it’s probably the most…
Morning neck pain almost always has a measurable cause: your pillow height. We break down the mechanism, the evidence, and how to adjust it. You wake up, turn your head, and there it is: that stiffness that takes half the morning to fade. It’s one of the most common complaints in physical therapy clinics, and…
Adipose tissue has a branding problem. In casual conversation “fat” is shorthand for something to minimize, but as a tissue it performs jobs that have nothing to do with aesthetics: insulation, cushioning, hormone production, and one of the body’s two ways of generating heat. Understanding what adipose tissue actually does changes how it shows up…
Bone often gets treated as the fixed scaffolding the rest of physiology happens on — the thing that stays still while muscles, blood, and nerves do the interesting work. That’s a mistake. Bone is a living, constantly remodeling connective tissue, and understanding how it rebuilds itself is central to managing fractures, osteoporosis, and almost anything…
Understand the physiology behind heat and cold therapy in physical therapy — when to use each modality, how they work, and what the science says about their effects on healing. “Should I put ice or heat on it?” It is one of the most common questions physical therapists receive. The answer, according to modern physiology…
Understand the biology of pain — from acute nociception to chronic sensitization — and how physical therapy uses pain neuroscience to reduce chronic pain and restore function. Pain is the most common reason people seek physical therapy. Yet despite its ubiquity, pain remains widely misunderstood — both by patients who experience it and, historically, by…
Understand how the body maintains pH balance, what happens during exercise-induced acidosis, and how acid-base physiology relates to physical therapy and rehabilitation. The human body is remarkably sensitive to changes in its internal chemical environment. Among the most tightly regulated variables is pH — the measure of acidity or alkalinity of body fluids. A shift…
