CBF Fast & Furious
There are lots of physical abilities to see as these CBFers sprint, which is a high-intensity activity with big benefits.
In this video, you’ll first see a side view at normal speed, followed by slow motion. Then you’ll see a front view.
Here’s what’s worth noting in their sprinting:
- They start with slight forward lean to drive off their toes, and sustain this form over the distance. The downward thrust of the foot is called plantar flexion, the same movement used when walking, but now done with a fast, powerful contraction of the calf muscle.
- While sprinting, they go from toes, to the bottom of the foot, back to toes. While sprinting the foot literally springs off the surface, making the entire body slightly airborne. It’s harder to generate power and speed if you are flat-footed and upright.
- Arms driving forward as the opposite legs extend backwards help lengthen the stride and increase speed.
- There’s really good form shown in the front view – nobody bobbing sideways, arms swinging forwards with no wasted motion.
So what’s sprinting got to do with real life? Don’t most people just need to walk to the car or refrigerator? Lots…
- You might need it to survive, like getting across a street quickly to avoid traffic.
- The powerful leg movements enable you to walk with a faster gait. Gait speed is associated with longevity.
- Sprints develop and preserve Type II muscle fibers, which are predominately the type lost in older adults that make them rickety and unstable. Walking doesn’t.
- Sprinting optimizes lung and heart capacity, both volume and endurance.
- Sprinting improves balance.
- Sprinting promotes ankle mobility and strength.
Next time you watch a track meet on TV, spot the sprinters. They’re the ones with the toned, sculpted bodies. (Not that anybody at CBF really cares about that, much.)
If you want to elevate your fitness, do some sprints outside the gym. They don’t have to be long. Just start with five sprints for 25 yards. That’s a perfect use for all those parks with nice green grass.
Born to sprint.
