The Art of Jumping
Jumping – lifting your body against gravity, feet rising off the ground, a moment of weightlessness, then coming back down. There’s no other sensation like it. In our sit-on-your butt society, especially among 50+ adults, it’s an endangered art. However, at CBF, we constantly train for and practice jumping.
Here’s why. Jumping develops leg power. Leg power enables dynamic balance and agility. You need power to walk, run, dodge, push, pull, bound, leap, punch, and play. Once your leg power starts to fail, your world gets smaller, more limited and dangerous, and much less fun.
Here are some positive signs of fitness in this video:
- These jumpers have developed strong muscles and tendons in their feet and lower leg that enable them to rapidly spring up off their feet.
- Their foot action is coordinated with and augmented by forceful contractions in the large muscles at both the knees and hips that accelerate them upwards.
- Upon landing, the very same muscles in the legs and hips that contracted to lift them up are then stretching to decelerate the force as they come down. Their landings are safe because they have the leg strength to absorb their full body weight in those large muscles, without transferring any undue stresses to weaker body areas, especially in the lower back.
- From head to hips they remain long and straight, centered between bending knees that do not collapse inwards upon contact. As a result, they make controlled landings.
They jump so confidently and safely because they have done lots of foot stretching and strengthening, innumerable squats and lunges with various loads for hip and knee strength, and many planks to develop their cores.
Cool music. Cool jumpers.
