The Physiology of Myoride Exercise

Energy should be one of the most important outcomes of exercise. Yes, there are other reasons to exercise.

Exercise...

  • improves the response to demands on the body
  • improves weight control and maintenance
  • lowers the risk of many diseases
  • improves cardiac function
  • builds and tones muscles
  • generates energy by developing mitochondria
  • builds the aerobic energy system
  • builds the anaerobic energy system
  • reduces high blood pressure
  • metabolizes fat
  • improves breathing
  • improves sex
  • improves sleep
  • improves attitude
  • relieves stress and anxiety
  • improves brain function
  • decreases risk of dementia
  • improves glucose and fat metabolism
  • improves cholesterol ratios
  • acts as an antidepressant
  • reduces effects of aging

 

But if I had to choose the overall, most important physiological result of exercise it would be energy production.

So we must talk about ATP and what happens during exercise.

There are many high energy metabolites in the body, but only ATP (adenosine triphosphate) can be used directly to supply the energy needed for the actual mechanical work of exercise.

In low to normal physical activities ATP is easily metabolized to create energy and easily re-supplied. You can make it through the day without any energy problems; your movements are good, your mind thinks clearly, and you can handle the challenges of the day. You can even exercise and feel refreshed.

But the more active you are — the more muscles that are engaged in work — the more ATP is used and then needed to be restored.

As the exercise becomes more intense, the rate of ATP used for energy increases beyond the ability for ATP production to keep pace. At this point, you will either fatigue quickly and stop exercising or reduce your exercise to a lower intensity so your rate of ATP production keep pace with your rate of ATP metabolism.

ATP breakdown and production is directly dependent on the exercise intensity. As exercise intensity increases, more ATP is generated to supply the muscles for work while other biochemical pathways are turned down to save the vital ATP for muscle contraction.

Since oxygen is needed for ATP production, the rate of oxygen consumption increases during exercise — the more intense the exercise the higher the rate of oxygen consumption. Oxygen is combined with ADP (phosphorylation) to produce ATP to make energy in muscle mitochondria. This happens every time you go from rest to exercise.

Aerobic metabolism.

If your activities are light you are using mostly aerobic metabolism — oxygen — to produce ATP in muscle mitochondria. Light activities lasting more than ten minutes use the aerobic pathways to make energy with ATP. There is enough stored ATP in muscle mitochondria to use for light activities.

Anaerobic metabolism.

When the demand for energy becomes greater or there becomes an inability to supply oxygen as in high intensity exercise the anaerobic pathways — glycogen/ lactic acid systems — are used to make energy.

High intensity, short duration exercise is the key to maximum gains and minimal catabolic (breakdown) damage from exercise because when the biological processes are maximally stressed for a short period of time the body responds with appropriate responses to the specific stresses — the Specific Adaptation to Imposed Demands (SAID).

In other words, when you continually overload a system, it will respond and adapt. When you engage in high intensity physical exercise, the stress imposed by even a single bout of exercise will elicit an immediate response by the body.

If you exercise intensely just several times a week for a few months the body will make long-term adaptations to the continual stress of regular exercise.

The best exercise is the one that engages large muscle groups that can be maintained in work continuously over time.

To gain even greater physiological effects the muscles should be moved through their complete range of motion against resistance. Not only will this engage more muscle fibers, more of the brain will be activated and help train a greater biomechanics of the muscles and joints and coordination of the body.

The higher the intensity, the more muscles engaged, through their complete range of motion, the better the effects of the exercise.

The Myoride exercise machine is the only exercise that can satisfy this criteria.
