Fascia 'pulling your head forward' when kicking

 I was recently consulted for advice, by an elite Japanese karate competitor, about “…the breaking of ‘head/neck posture’ when kicking”: especially when moving with maximum speed/intensity. This article fundamentally addresses this issue. Needless to say, depending on the type of kick, launching position, and so forth, there are differing precise formulas to overcome this issue. 

Today, I will provide a generic answer.

When your head involuntarily pulls forward when making 蹴り技 (keriwaza) it usually indicates that you are experiencing a ‘fascial compensation pattern’ that is primarily caused by the SBL (the ‘Superficial Back Line’) and/or the SFL (the ‘Superficial Front Line’).

This is because fascia connects the body from your toes to your forehead; therefore, tightness at one end of the fascia line will pull on the other end to find ‘extra slack’. Thereby, as you extend your leg the head can potentially be brought forward.

Why the Fascia Pulls Your Head Forward?

① Tight Hamstrings on the SBL

The Superficial Back Line is a continuous sheet of tissue that runs from the bottom of your feet, up the calves and hamstrings, along the spine, and over the skull to your brow.

• When a kick is thrown your kicking leg puts a massive, rapid stretch on the hamstrings.

• If your hamstrings or lower back fascia lack elasticity, the line runs out of slack.

• To compensate for this stretching action, the body steals length from the top of the chain; thus, pulling your head/neck forward. 

② Guarding Response of the SFL

The Superficial Front Line runs from the top of your toes, up the quadriceps, through the abdominals, and attaches to the base of your skull (the mastoid process).

• If you hunch or tense your chest to brace for impact, thefront fascia shortens.

• This tightening pulls the base of your skull downward and forward, causing a jutting chin. 

How to Fix It?

Release the Anchors (Roll the Feet)

You can directly increase your head and neck mobility by releasing the bottom of your chain. 

• Use a lacrosse ball or tennis ball to roll out the plantar fascia on the bottom of both feet for two minutes before training. 

• Because it relaxes the start of the SBL, this instantly creates slack all the way up to your neck and allows for freer head movement.

Intentionally Tuck the Chin

Consciously combat the pull by keeping your neck structurally stacked. 

• Do not look up at the ceiling or overextend your throat when kicking.

• Keep your chin slightly tucked and your eyes fixed forward on your target. This places the upper cervical fascia under tension, preventing it from yielding to the pull of the legs.

Dynamic Chain Stretching

Instead of just holding passive hamstring stretches, train your fascia dynamically.

• Perform slow, controlled standing leg swings to load the tissue at both ends.
• Focus on keeping your upper body perfectly vertical and your spine neutral while the leg moves.

To conclude: This issue is natural when kicking and impacts all karateka from time to time. The main point—if and when this happens—is to recognize it and utilize corrective methods. As a professional karate instructor, it is imperative for me to optimize my own technical in my daily self-training; furthermore, ensure that all karateka—whom I coach as Renshusei and in Seminars —maximize their skill. While this article has been highly generic it elucidates the point of ‘professional practice and development’.
