May 28, 2017 - Max Speed

5/29/2017

1 Comment

 
You just heard the starting gun of the race, you're angled 45 degrees, driving your legs and doing great. Now what? After the first few strides, gradually lean up with your torso so there's a 5 degree lean. Your stride length and frequency should hit top gear. Your eyes should be focused straight ahead. Within 20 meters you should have some of these technique points:
  • Minimal Ground Contact Time - Think like you're running across hot coals. You're applying as much force as possible down and back. Elite sprinters like Andre DeGrasse have contact times around 0.1 seconds on the ground!
  • Leg Kick - The back leg (hip, knee, ankle) fully extend during propulsion. But then your knee should kick back up towards your butt as the leg swings through. This decreases the lever of the leg, making it easier to swing forward
  • Posterior Pelvic Tilt - This point is really important. Posterior tilt is when the pelvis slightly tucks under. Having a bit of tilt allows the runner to drive the hip tighter. Why is this important? It allows you to apply more force down to the ground and can increase stride length by about 3cm!
If you look at the final stretch of an Olympic race in slow-motion, often the top runners are in posterior pelvic tilt. While the losers are in forward pelvic tilt!

May 21, 2017 - Starting Fast

5/22/2017

Having a great start doesn't make or break a race. But it really helps. this is where muscle strength and power make a big difference. However technique is still key. The main points to accelerating quickly (in running or any sport):
  • Body Angle - You want to aim for around 45 degrees. You want the chest and eyes angled to the ground, this relaxes your back and neck muscles
  • Triple Extension - the back leg should have full extension of the hip, knee and ankle for the first strides, to maximize power generated
  • Triple Flexion - the lead leg should have great flexion of the hip, knee, and ankle with foot contact (like a coiled spring)
  • Arm Swing - you want big, powerful arm movements to counterbalance the opposite leg movements. Front arm should flex high with elbow 90 degrees, back arm should fully extend
All of these techniques work to convert energy horizontally and forward. If your arms aren't moving correctly you lose energy sideways. If your torso angle is too vertical you lose energy upwards. Counterbalance is key, because leg forces can be more than 1500 Newtons of force! Tomorrow I'll talk about accelerating and hitting maximum speed

May 14, 2017 - How to Run Faster

5/15/2017

0 Comments

 
Growing up everyone had that one gym classmate that could just burn you in a race. You always heard a common phrase from teachers and coaches: 'You can't teach that speed'. This is true to an extent, but my belief is that these kids just have a knack for the fundamentals of running fast. Some of these techniques can still be taught. As a refresher from the last running series: running is a simple formula:

SPEED = Stride Frequency X Stride Length

If you look at the 100m dash finalists, they're all different heights, weights and muscle sizes. Each has found their own way to manipulate the number or length of their steps to be lightning fast. The legend Usain Bolt for example has a big advantage with his monster leg length. He only needs around 40 steps for the 100m dash!

All this speed comes at a cost. The faster you run the bigger the muscles you end up using the more energy you use. For example when sprinting you're using more glute max and hamstrings; whereas jogging you use more calfs and lower leg muscles. But a lot of the same rules apply as jogging:
  • Good Torso Positioning
  • Limit Overstriding
  • Neutral Food Strike
  • Limit Vertical Bouncing
There are obviously some technique differences but your goal is still similar: efficiently convert as much energy as we can forward. Next posts we'll get into starting and accelerating

May 7, 2017 - Simplicity is the Ultimate Sophistication

5/7/2017

Da Vinci was quoted saying this over 500 years ago. It means that knowing something in mind-numbing detail often does not make it useful. It can actually take more time having a complex idea and converting it into something simple. 

The next time you work out, or are trying to get your injuries better, think: 'Is this program or exercise really necessary for me to get to my goal? Or can I do something easy but consistently to be more successful. 

Doing simple tasks really well, is true complexity.
