Arms

Lance Smith explains why the arms are the rudder, accelerator and gear lever of running.

Arms and how you use them can have a positive or negative effect on stride rate, stride length, ground forces and energy consumption.  And that surely is the basis of effective running – stride rate – stride length, ground forces, energy use – it is these that determine how fast you run. While arm action is not the only technical aspect of running you need to work on, it is the one most ignored – and to run well everything must be working perfectly.  Everything.  You cannot afford to ignore any of it.

Arm movement is considered by many to be determined by legs – where legs go arms follow but it is the other way around - arms control the legs.  Arms are the rudders, accelerator and gear levers of running and jumping. When you see a runner moving awkwardly, bad running mechanics, a weakness in technique, look at what the arms are doing – it could be an incorrect or inefficient use of arms is causing the problem.

Peter Coe, coach and father of Seb stated that good technique will not guarantee you will be a good runner but bad technique guarantees you will not be.

Rudder

Running action causes rotation around the vertical axis – right foot pushes, the body turns to left – like the action of rowing a boat.

Try and run with your arms held straight at your sides.  Notice how your shoulders swing from side to side. 

Flexing of elbows in arm drive reduces this rotation and transfers rotation movement to rest of the body – instead of zig-zag movement, it is all forward, the way you want to go.

If you run with your arms bent at an acute angle you will also have this rotation from shoulders  – there is no flexing at the elbow because at this angle there cannot be.  This is same as having arms straight – rotation from side to side.  

It means you restrict forward motion by having zig zagging.  What does this do?   The body will try and achieve stability by using other muscles   - the shoulders as we have seen, core particularly and limb muscles not used for moving forward at pace.  This is energy wasted.  Muscles and energy used for anything other than effective forward movement is wasted energy

Note, while flexing arms at elbows helps reduce rotation around the vertical axis, it must be in combination with total arm swing from shoulder – it is an opening up of arms and closing as they drive forward and back.

We do not want movement from the elbow with a lower arm in motion and upper arm still and we do not want to march -  arms moving and no bending at the elbow.  

Accelerator

While you run on your legs, you run with your arms - arms do not carry you down the track, but they do dictate to what does. Julian Goater in his book The Art of Running faster makes this statement: "Your arms will move as fast as they need to in order to keep up with your feet, right? Actually, it works the other way around."

Goater tells when he was shown by a coach how to use his arms – something he never thought of before -   the coach said he needs to feel as if he is pulling himself along, with the action behind the body, pulling downwards and backwards.

Tom Tellez, coach of Carl Lewis stressed the same thing another way when he said you must have a fast downward stroke of the arm.   And I emphasise the "stroke" – hands sweep down and behind the hips, they do not go forward and back like a piston.

When the arm is driven hard up (milking the cow) it lifts the opposite knee.   And when driven fast down drives the knee forward.  

I have a maxim – run with your knees, not your feet. The downward drive of arm promotes running with knees – knees driving forward.  Upward drive gives the feeling of running on the spot.   I maintain it is a mistake for coaches to yell "lift your knees".  The correct call should be "drive your elbows".  As with run with the knees, not the feet, arm drive is with elbows, not the hands – and vigorous arm drive will drive knees.

However, the upward drive observes Newton's law of opposite forces – the opposite force of arm going up and forward is support leg going down and back - pushing runner forward, increasing stride length.

So downstroke increases leg turnover while upstroke increases stride length.

You cannot afford to be passive in either

Vigorous downward stroke brings the opposite arm up – but notice, when up is the dominant force the other arm is not driven so far back so there is less action behind the body, less pulling yourself along.

High skip is a drill for arm use.  Hard to skip without vigorous arm action and focus on a downward sweep that influences skip speed.

If arm action is too much forward and not enough down and back imagine hammering a nail in a wall behind you– the hand is the hammer.

And think about driving the elbow down rather than hands.

Putting it all together

  • Pivot is at shoulder – arms move from shoulder, not elbow
  • Arms drive down in vigorous stroke, driving the other arm up
  • Driven back to ensure action is behind the body.  How do you learn and practise this?
  • Hand drive starts eye height and hand passes pocket – pick your nose – pick your pocket.  If hand not at pocket height elbow angle is wrong.
  • Hands need to be relaxed but not floppy or out of control – you do not want them going in a different direction to arms.   The hand needs to point in the same direction and moving in the same direction as the forearm.
  • Elbow and hands must follow the follow same path.
  • Holding hand open uses energy – tenses arm muscles – while it gives slightly longer lever and able to generate fraction more ground forces it costs in tension which is not good for fast running  
  • And most important … the link between arms and legs are core muscles – weak links compromise everything.
