Biblioteca de fisiología aplicada a la fisioterapia, en inglés.
Understand the three phases of tissue healing — inflammation, proliferation, and remodeling — and how physical therapy supports each stage of the regenerative process. The human body’s capacity to heal itself is one of nature’s most remarkable achievements. A broken bone rebuilds itself to near-original strength. A torn tendon gradually restores tensile capacity. A skin…
Compare how the nervous and endocrine systems regulate body functions, what each contributes to physical therapy outcomes, and how therapeutic interventions target both systems. The human body’s internal communication relies on two master control systems: the nervous system and the endocrine system. Both systems detect changes in the body’s internal and external environment and coordinate…
Learn how the body burns fat through beta-oxidation, why low-intensity exercise maximizes fat use, and how fat metabolism supports physical therapy recovery programs. «Burn fat, not sugar» — a phrase often heard in fitness circles. But what does it actually mean biologically? The answer lies in a metabolic pathway called beta-oxidation: the process by which…
Learn what enzymes are, how they accelerate biological reactions, and how enzyme activity relates to muscle injury, inflammation, and physical therapy recovery. Without enzymes, life as we know it would be impossible. The chemical reactions required to sustain life — from digesting food to building muscle proteins to generating energy for movement — would occur…
Explore the components and functions of blood — red cells, white cells, platelets, and plasma — and understand how blood supports tissue healing and physical therapy recovery. Blood is often thought of simply as the liquid that flows through our veins. But blood is, in fact, a highly sophisticated connective tissue — a fluid matrix…
Discover how cell organelles like the Golgi apparatus, lysosomes, and endoplasmic reticulum work together to support tissue healing and recovery in physical therapy. The interior of a human cell is not empty space. It is a bustling, organized metropolis filled with specialized structures — organelles — that each perform a distinct and vital function. Just…
Learn how platelets and the coagulation cascade stop bleeding, initiate healing, and how platelet biology informs physical therapy and PRP treatments. Every injury that breaks blood vessels — from a minor skin abrasion to a surgical incision, from a muscle tear to a fractured bone — must be met with an immediate response: stop the…
Explore how testosterone drives muscle growth and recovery, how it affects rehabilitation outcomes for men and women, and the role of physical therapy in optimizing muscular health. When people talk about building muscle, testosterone is usually the first hormone that comes to mind. And for good reason: testosterone is the primary anabolic hormone in the…
Learn how the Krebs cycle generates aerobic energy in the mitochondria, why it matters for endurance and recovery, and how physical therapy leverages this metabolic pathway. If you have ever wondered what actually happens inside mitochondria when you exercise, the answer lies largely in a series of eight chemical reactions called the Krebs cycle (also…
Learn why water is the most essential molecule in the human body, how dehydration affects muscles and joints, and why hydration is critical in physical therapy. It is one of the most abundant molecules on Earth and the most essential for human life. Water makes up approximately 60% of adult body weight — around 42…
