Is our Biology a mismatch for the modern world? Statistically Depression is on the rise but why? Well there's no single conclusive reason but as a society becoming more and more sedentary, consuming industrialized food highly altered from its natural form there seems to be a parallel in its effect on society. The more the modernization of society, the higher the Depression rate climbs. While it might appear somewhat perplexing, it's actually quite simple: humans were not well designed for the modern industrialized world. Science is realizing there's true concern for our processed eating habits in the way we consume food chemicals, pesticides, hormones and how behavior and moods are affected by it. That coupled with lack of movement or exercise and you have a perfect storm for where we're at. We evolved in natural habitats where we ate real food and were very active, unfortunately technology in a short time has altered that dramatically. While I'm certainly not against technology as I use its numerous benefits, there has to be a responsible balance which our society has not mastered yet. Thankfully the organic food industry is gaining momentum both price wise and supply wise and the fitness industry continues to grow, although slowly. Our awareness and education is our best ally. No matter how hard we try we can't get away from who we are and how we evolved.
If you spend any time talking to evolutionary scientists, they'll
tell you that an organism's structure evolves to cope with the
stresses to which it is subjected. This idea has led to the theory
of adaptation -- that an organism's structural design is regulated by
its functional demand. Remarkably, structural changes also occur in the short term in response to exercise training: bones increase their density, muscle fibers increase their metabolic efficiency, and cardiac muscles grow stronger. If the quantity or structure incorporated into our system is matched to what is needed, it's logical the amount of change that takes place to match the increased need. And that's exactly what happens when we train.
Following a training stress, your body adapts and physiologically
overcompensates so that the same stress, when encountered again,
does not cause the same degree of physiological disruption. In
short, your body adapts to be able to handle the stress. Following
the adaptation, your body can do more work. The aim of training,
therefore, is to introduce training stimuli in such a fashion that
higher and higher levels of adaptation are achieved. If you
repeatedly threaten the body's survival, you will cause adaptations
to be made to counteract the threat. A classic example of this is
the long run of marathoners. Repeatedly running for long periods
of time (longer than two hours), presents a threat to the muscles'
survival by depleting their storage of preferred fuel (glycogen,
the stored form of carbohydrates). If you run out of fuel, the
muscles say, "Hey, this person is running for so long that I don't
have any more fuel. I won't be able to survive. If this activity
is going to be a regular habit, I need to make more fuel." So,
guess what happens? When you consume carbohydrates following
your long run, you respond to the empty tank by synthesizing and
storing more glycogen than usual in your skeletal muscles, thus
increasing your storage of fuel (and therefore your endurance)
for future efforts. Imagine if you kept driving your car until
the gas tank was empty and your car responded to that threat by
making its tank bigger so it could hold more gasoline. Pretty
Unfortunately, our ability to adapt to a training stimulus doesn't
keep occurring indefinitely. There will come a point, which is
specific to each person or athlete, when more training, at best, does not lead to better results and, at worst, causes injury. The main difference between Olympic athletes and the rest of us is that Olympic athletes continue to make physiological adaptations with more and more training, though the increases become micro adaptations at some point.
