Votre fréquence cardiaque vous parle, mais vous ne l'écoutez pas

▶️ Your power output is stable. Your pace is stable. And yet your heart rate keeps rising. Why? This gradual increase in heart rate despite a constant intensity is called cardiac drift. And contrary to what many triathletes believe, this metric can reveal far more about your future Ironman than your FTP, VO₂max, or critical power. In this video, you will discover: ✅ What cardiac drift actually is ✅ Why it occurs during exercise ✅ The 4 main culprits: Dehydration Heat Muscle fatigue Glycogen depletion ✅ How to easily measure your cardiac drift using your training files ✅ How to interpret your results (less than 5%, 5-10%, greater than 10%) ✅ Why this data is directly linked to your endurance and your ability to perform in an Ironman Because in long-distance events, the problem isn't always the size of your engine. The problem is often your ability to maintain your performance level as fatigue sets in. ------------------------------------------------------ 0:00 The statistic 90% of triathletes don't know 0:55 The mystery of the second file 1:53 Identifying the suspects 4:13 The verdict 5:33 How to measure your heart rate drift 6:51 What your heart rate drift says about you 7:42 How to interpret the results 9:08 How to improve it ----------------------------------------------------- ★ Book your Free Discovery Session for Personal Coaching for Your Ironman and 70.3 goals: https://calendly.com/rlsportcoaching/... 🌍 To follow my 70.3 & Ironman Self-Directed Training Plans: 👉 https://www.rlsportcoaching.com 🌍 My Precision Hydration Product Shop: 👉 https://www.rlsportcoaching.com/categ... 🔔 Subscribe to my channel so you don't miss any of my Triathlon & Swimming Training tips!    / @rlsporttriathloncoaching
