¿La alta intensidad desarrolla mitocondrias? La respuesta que casi nadie explica
Does high intensity training really build mitochondria? This is one of the most repeated — and most misunderstood — ideas in modern endurance training. For years, athletes have been told: 👉 easy training builds the aerobic system 👉 hard training builds performance But real exercise physiology is much more complex. In this video, I explain from a scientific and practical perspective: 🔥 What high intensity REALLY does at the mitochondrial level. 🔥 Why signaling is not the same as long-term adaptation. 🔥 The true role of lactate as a metabolic signal — not just a waste product. 🔥 Why many athletes improve numbers but still don’t perform better. 🔥 How to combine high intensity and aerobic base training correctly. 🔥 Why metabolic efficiency matters for endurance performance. We also discuss: ✅ Mitochondrial adaptations ✅ Lactate physiology ✅ Zone 2 and aerobic base ✅ VO2max training ✅ Endurance performance ✅ Fatigue and recovery ✅ Exercise physiology Based on the scientific literature and concepts from: Brooks • San Millán • Gladden • Seiler. If you want to understand endurance training beyond social media myths and oversimplified advice, this video is for you. 👉 Subscribe for more videos about endurance science, cycling, running, triathlon, metabolism and exercise physiology. 📘 Book: Soul and Wheels 🧠 eBook: The Mind Wins First 🌐 More resources: AlanRoca.com #Mitochondria #VO2max #Zone2 #EnduranceTraining #Cycling #Running #Triathlon #SportsScience #ExercisePhysiology #Lactate
