Abdou reached 34 meters his best dive yet. This dive shows how small technical details can completely change energy efficiency underwater. When a diver is not streamlined knees bent, fins wide, arms loose drag force can reach around 54 newtons. In perfect alignment head down, body tight, fins in line — drag drops to about 20 newtons. Let’s see what that means 👇 ⸻ Example: 34 m Ascent Work = Force × Distance • Messy form: 54 N × 34 m = 1,836 joules • Perfect streamline: 20 N × 34 m = 680 joules 🔹 Energy saved: 1,836 – 680 = ≈1,150 joules 🔹 That’s ~63% less energy spent fighting drag. ⸻ At depth, that efficiency lets gravity pull you down at 1 m/s with zero effort — then saves oxygen on the way back up when it matters most. Less drag = less effort = more depth and more safety. #freediving #freedive #freediver #apnea #freedivinglife #freedivingtraining #freedivingphotography #oceanlife #underwaterworld #onebreath
