Training on Cardio exercise more then 15/ 20 minutes can be proven VERY DANGEROUS to your health's and life's longevity,
Please note heart is a muscle, which is exercising passively (constriction/ pumping blood even when we are sitting in relaxation),, in cardio engaged exercise it starts functioning at 6 times rate of its normal capacity, but obviously actin and myosin (muscle fibers) will do their job of growing in response to the activity of contraction, leading to LVH (left ventricular hypertrophy) and plaque issues, this process is IRREVERSIBLE, and an very expensive medical affair with additional emotional apathy.
Recommended period for cardio is maxx 15 - 20 minutes, just to maintain the cardiovascular flow required to maintain offset/ recreational activities of our life.
Other adversaries included are
Increase in CORTISOL-
Cortisol, also referred to as the "stress hormone," it is an essential hormone to the body, as it's responsible for regulating our energy needs and waking us up in the morning, high circulating levels creates confusion and it also shifts the condition to store fat, especially around the abdomen.
When the body is under stress, cortisol comes into play by storing fat as our fuel back up, it's not an ideal state to be in, on any regular day.
Lowering of Testosterone, T3 and Catabolism of adipose tissues (fat)
Prolonged, intense cardio sessions will alter in output of T3 and potentially impairing future hormonal response, which will further disturb the metabolism, similarly hormones like testosterone and HGH flow (it is believed /myth that these 2 hormones are of concern only to men who lift heavy weights),,,,,, BUT, it's important to note that these two hormones are extremely important for anyone, male or female, trying to lose fat and gain muscle. research has shown that HGH is one of the premier hormones that promote synthesis of protein tissues and aids in metabolizing body fat for energy.
Interestingly, steady-state cardio has been also shown to lower both testosterone and HGH, which not only inhibits/ stops fat loss but can also cause fatigue, hot flashes, irritability, decreased muscle mass, and decreased bone density.
So if you are thinking cardio workout would assist you in fat burnout then you are in absolutely in wrong concept of mind..
Its high time for you to reset your goals, with proper guidance of a professional health and fitness coach.
Your goal could be just
- Stay in healthy range of motion for day to day activity
