Native Physical Fitness is a term that refers to the fitness capability that over 100,000 generations of humans have provided us through primal necessity and natural selection. True physical fitness that fits our bodies needs. What am I talking about? Let’s see how this evolved fitness relates to our current trend toward aerobic and sustained physical health. Native Physical Fitness is the physical stamina that served our ancestor Cavemen. It gave them the burst of speed to escape danger, or capture food. It gave them the energy to fend off predators or enemies. It was on-demand power for personal and group survival.
This Physical Fitness platform has been refined over countless generations to meet the needs of our body musculature and bone structure. It serves our lungs, heart, and brain so that it keeps the body fit and whole and ready for action. It has evolved over 100’s of years of refinement so that our bodies worked to peak performance without sustained exertion and continuous activity. Cavemen did not run for 26 miles at one time, or jump around inside their caves for an hour sweating to the rhythm of a drum (the original BOOM Box). Where they physically fit? I would say that you and I are here so that is a testament to their fitness. Is sustained physical effort and/or extended aerobic activity, espoused by today’s physical fitness Guru’s, better for our muscles, internal organs, or bony frames?
Not in all instances!
Medical science is finding that our current trend toward physical routines is hurting us much more than helping. Studies have shown that Caveman had the fitness capacity to meet instant demands of physical effort. A large heart and expanded lung capacity gave him the fuel and energy to meet his limited effort for survival. After this burst of energy it was followed by rest, not prolonged physical activity. Conversely, today’s runners in many instances have a smaller heart to sustain the continual, limited, demand that is placed on it by prolonged activity. Our bodies become efficient and actually adjust to the demands we place on it. It will conserve the capacity of the heart and lungs to sustain long periods of exertion and actually re-tool the muscles, heart and lungs to meet the physical demands placed on it.
