Steroid danger
Type-I fibers are considered low growth potential aerobic oriented muscle fibers and type-II fibers are considered high growth potential anaerobic/strength muscle fibers. steroid danger Are-epidural-steroid-injections-dangerous. Obviously the greater an athlete's muscle fiber ratio favors type-II fibers, the greater the potential for muscular growth and strength increase. The ability to alter the ratio through specific training protocols means also the ability to effectively alter genetic make-up. A study done in Oslo, Norway examined long term and short term (acute) hormone responses of 9 experienced test subjects to two different training intensities. steroid danger Clenbuterol steroids. The high intensity work-out required the test subjects to perform free bar back squats (front and back) using 100% of their 3 rep max for sets. The moderate intensity work-out required the athletes to do the same exercises utilizing 70% of their 3 rep max for sets. Rest periods were 4-6 minutes. steroid danger Effect-of-anabolic-steroids. Results Of The StudyThe test subjects blood samples were taken before, after 30 minutes into, and every 15 minutes for the first hour after each work-out. Next, blood samples were taken at 3, 7, 11, 22, and 23 hours post work-out. The analysis of the blood samples was for:Hormones positively affecting anabolism (tissue synthesis): LH (leutenizing hormone), FSH (follicle stimulating hormone), testosterone (free), insulin, growth hormone (GH), and insulin-like growth factor-1 (IGF-1). Hormones that affect catabolism (tissue wasting): ATCH (adrenocortotropic hormone) and cortisol. Other substrates analyzed include creatine kinase and lactate. (As indicators of actual training intensity)The test results verified that high intensity training induced a significantly higher level of testosterone and cortisol secretion (and moderate intensity did not) as a short term hormonal response. Though both testing protocols showed a decreasing testosterone level in the post-training hours, the high intensity training results were consistently higher than those of the moderate intensity. LH and FSH levels were not significantly altered as a result of either training intensity. This is a huge finding that exceeds the evidence of higher intensity training protocols being the better method for triggering a significant increase in testosterone. The majority of endogenous (naturally produced inside the body) testosterone synthesis in males is handled and regulated by the hypothalamus-pituitary-testes-axis (HPTA). It all begins when the hypothalamus receives neuro-net impulses that signal the release of leutenizing-hormone-releasing-hormone (LHRH) which in turn tells the pituitary gland to release leutenizing hormone (LH). LH then makes contact with the testes Leydig's cells that produce testosterone and release it into the vascular system. However, there is a secondary testosterone synthesis pathway that may be hyper-activated as a result of high intensity training protocols. The adrenal glands produce several different hormones. The hormone of interest for this issue is called dehydroepiandrosterone (DHEA).
