Hidrodinámicos: delfines frente a hombres

The video discusses the differences in swimming speeds between humans and dolphins, highlighting the hydrodynamic advantages dolphins have due to their body structure and skin properties. Dolphins swim faster because their bodies are more streamlined, and their skin is thicker and sheds frequently, reducing resistance. Humans have attempted to mimic these features with swimwear and techniques, but dolphins remain superior swimmers.

What is the maximum speed that top human swimmers can achieve?

• 15 km/h

• 7 or 8 km/h

• 10 km/h

• 5 km/h

Why do dolphins swim faster than humans?

• They have larger fins.

• They have more powerful muscles.

• Their bodies are more hydrodynamic.

• They swim in groups.

What is one reason water slows down human swimmers?

• Humans swim against the current.

• Water deforms human skin, causing resistance.

• Humans have thicker skin than dolphins.

• Water is less dense than air.

How often do dolphins shed their outer skin layers?

• Every day

• Every month

• Every 2 hours

• Every week

What is one method humans use to reduce water resistance while swimming?

• Using larger paddles

• Swimming in warmer water

• Wearing swim caps

• Using heavier swimsuits
