Giữ thăng bằng khi bơi sải: Vai trò của đôi chân (Chữ H số 3) | Gopeaks

Hello everyone, Vishark is back with the final article in the Human Body Position module!

We’ve journeyed together through the foundational steps: building the “3H Axis” framework, assigning roles to each part, placing the “Head Rudder” (H #1) in the right spot, and listening to the “Hip Conductor” (H #2) guide the rhythm.

Today, we’ll complete this trio with the lesson on H #3: Heel – the role of the feet. This is the most misunderstood part. Some people kick too hard to swim fast and get exhausted; others let their feet sink like a rock. So what is the true role of “H #3” in maintaining a perfect swimming position?

Article Objectives

After reading this short article, you will:

Understand the 3 main roles of the feet in maintaining proper body posture.
Recognize common mistakes that turn your legs into a “brake.”
Have exercises to feel how the feet contribute to balance.

The Role of the Feet in Maintaining Form

For this section, forget about kicking to generate propulsion. Your feet have 3 quiet but crucial tasks:

Support the posterior body
A smooth, gentle kick creates a stable flow beneath the body. This flow acts like a hydrodynamic lift, continuously supporting the hips and legs, keeping the 3H Axis parallel to the water surface.
Assist the ‘Hip Conductor’ in rotation
This is a subtle task. An active kick sets the rhythm for hip rotation. Specifically, when your right hip begins to rotate upward, your right foot simultaneously performs a strong, deliberate down-kick. This synchronized movement generates torque, helping the whole body rotate smoothly.
Maintain the Long Axis & Prevent Twisting
When your body tilts, the feet help it rotate as a unified block rather than twisting like a rag.

Common Foot Position Mistakes

“Bike Pedal Legs”: Bending the knees too much while kicking. This creates drag and sinks the hips.
“Plank Legs”: Ankles rigid at 90°. Instead of gliding, you’re braking the water.
“Splashing Legs”: Kicking with too wide an amplitude. Breaks the torpedo posture and destabilizes the body.

Practice Corner: Feeling Stability

1. Kickboard Drill
Goal: Feel the buoyant role of your feet.
How to do it: Hold a kickboard, arms straight, head down. Focus on gentle kicks from the hips. The goal isn’t speed, but to feel the hips and feet stay high and stable in the water while generating a continuous flow beneath.

2. Half Rotation Kick Drill
Goal: Feel how the feet maintain balance during body rotation.
How to do it: One arm extended overhead, the other along the body. Kick 6 beats on your stomach, then rotate your hip and shoulder (the arm along the body) upward while turning your head to breathe. Hold 6 beats on your side. Repeat. Kick gently to prevent rolling over.

Coach Vi’s Tips

“Imagine your feet never kick wider than your shoulders. Using the hips as the midpoint, kick forward as much as you pull back. A neat, compact kick keeps your body straight and stable.”

Summary & “Homework”

Summary: Feet help maintain buoyancy, balance, and provide rhythm for hip rotation.
Homework: During your next swim, try the Half Rotation Kick drill. Feel how your kick stabilizes your body when tilting.

We’ve now completed Module 1: Body Position! You now have the foundational tools to build a solid swimming posture. In the next module, we’ll “add the engine” to this machine. See you in Module 2: Propulsion!

Wishing you a strong foundation!

Sincerely,
Coach Vishark
