Discussion #2
-The importance of the endocrine system when designing a resistance training program:
The endocrine system releases hormones to help the body regulate and stabilize internally. When designing a resistance training program, it is important to look at the predicted outcome (for example: muscle growth) and see what hormones are linked to that predicted outcome. The goal is to get the best hormonal response from areas that will help guide you to the intended outcome of the program. If I was designing a program for strength and muscle growth (using the knowledge I have of the endocrine system), I know that human growth hormone and testosterone are the hormones that will play a large role there. Since testosterone directly interacts
Weight training is an important essential in life, but of course it’s not really needed. Weight training is a series of exercises that use weights for resistance. After lifting weights people feel different, like they have achieved greatness. Part of weight training is eating right and being healthy. In order to see progress good rest is required, or all the work done in the weight room was all for nothing.
The name “performance enhancing drug” is a name that categorizes a long list of drugs and treatments, but only a few can add an impactful boost on an athlete’s abilities. Many of these drugs promote or increase the production of cells within the body, taking them to levels beyond what could actually be produced. Anabolic steroids and human growth hormone are the primary PEDs used in the sports world because of the positive effects they are known to produce. Anabolic steroids help the body 's muscle cells produce more protein, which increase muscle strength, and more ATP, which is the fuel muscles need and use. Human growth hormone is something already produced inside the body which promotes
The endocrine system includes of specific tissues and glands which secrete chemical messengers to the body called hormones. The glands are aided by the nervous system and chemical receptors in the blood and other hormones produced by other glands. Hormones regulate many functions of the body such as cellular metabolism, reproduction, sugar and mineral homeostasis and digestion.
Testosterone is a hormone in both men and women, but in greater extent in the men, testosterone is a chemical compound (C19H28O2) and is responsible for the characteristic of men such as, sexual characteristics/sexual organs, deepening of the voice, and facial and body hair. (Neil Schlager, Jayne Weisblatt, and David E. Newton 2006) Testosterone/Steroids has bodybuilding and masculinizing effect as well as treating a variety of medical conditions, like asthma, the steroid is used in a puffer, they can be used for anabolic or androgenic purposes and made for synthetic purposes making them illegal. (BROWER, K. J. 2001) Many athletes will use these to gain an advantage on competitors, with lean muscle and higher endurance, with many uses, there
*Endocrine glands produce – hormones, they work with other hormones to perform many functions including: control water & electrolyte balance, regulating carbohydrate metabolism, working as neurotransmitters, maintaining stress & inflammation, regulate reproductive functions
I have organized the client’s training program with the major muscles first in the program after that I would repeat the muscles again. In addition, since the client had requested for 6 resistance training days I have strategized by splitting the major muscle groups into several days as seen in the client’s program. Furthermore, with having 6 days of resistance training it would be tough but with a mixture of upper and lower body days it would allow the client to recovery and build the muscles. Not only, he would be build muscles, he would improve in his speedball games.
One of the biomarker for overtraining is the hormone testosterone (Wyatt, Donaldson, & Brown, 2013). Normally testosterone is marker of anabolic status and accelerates growth in tissues and blood flow. Testosterone also interacts with the metabolic system and stimulates protein synthesis and red cell production (Wyatt et al., 2013). Overtraining can reduce testosterone, which may cause a reduction in protein synthesis, decrease red blood cell production, and delay overall recovery. Many metabolic changes are linked to reduced substrate availability, which suggests an over-reliance on the gluconeogenic process (Wyatt et al.,
Testosterone belongs to a class of male hormones called androgens that is vital for sexual and reproductive development. The National Institutes of Health regards “testosterone as the most important male hormone”(Rettner). Although the primary role of testosterone directly relates to males, women also produce testosterone at lower levels. Women’s total levels are about a “tenth to a twentieth of men’s levels”(Rettner). According to the Mayo Clinic, this hormone plays a role in sex drive, sperm production, fat distribution, red cell production, and maintenance of muscle strength and
This system enables specific signals to be sent and received by cells and tissues that are distant from one another. The endocrine system controls activities that take place in the body by releasing mediators, which are known as hormones. A mediator molecule can also be known as a hormone and it is released into one specific part of the body and normalizes the activity of cells in other parts of the body. Once a hormone is released it is transported to the target cells through the circulating blood in our bodies. Hormones in the body are significant in the processes of regulating growth, development, metabolism and
3. Perform ten resistance training exercises and describe which phase of the exercise is the eccentric, concentric and isometric phase of the movement. At which phase is the muscle the strongest? Why?
It stimulates growth and cell development and works with another hormone called insulin. Growth Hormone does help regulate metabolism in adults, but its main purpose is really to spur growth during childhood. Since 1985, an injectable form of HGH has been formed synthetically in the U.S.. The Food and Drug Administration approved to treat children with growth issues, genetic disorders and kidney problems. For adults, HGH might be recommended for conditions like bone loss, high cholesterol or very rare pituitary tumors. There’s been a study that reported a positive effect of growth hormone on athletic performance at the University of Queensland in Australia. Scientists in 2010 studied 103 recreational athletes and found out that while those taking HGH showed no improvement in strength or general fitness, their sprinting times on a bicycle improved 4% and that’s all. What they also found is that the performance improved with HTH with testosterone. Steroids are a kind of lipid or fat molecule and your body makes two very different types. You may be familiar with corticosteroids, they’re a hormone produced by your adrenal glands on your kidneys and they’re handy for things like immune function stress response in controlling inflammation. The other kind of steroids are Androgenic Anabolic steroids. The main one of these is testosterone which, as you know, produces male sex characteristics, but the steroids also include compounds that stimulate the synthesis of proteins and eventually new muscle fibers. This process is christened Anabolism and the steroids that drive it are our anabolic steroids. Synthetic versions are those that are abused by athletes because the combination of steroids and exercise can increase a man’s strength by more than 38% and its at least that high for women. Anabolic steroids can be freakishly efficient, especially when the user takes more than
a family of hormones that include the natural male hormone testosterone… These hormones have anabolic (“muscle building”) and androgenic (“masculinizing”) effects, resulting in increased muscle strength and athletic performance, at times beyond what could be attained naturally (7).
Sinha-Hikim et al. observe that testosterone induces skeletal muscle hypertrophy, increasing the size of both type I and type II muscle fibers, by acting at multiple sites within the muscle through multiple mechanisms (Sinha-Hikim et al 2004). Their study found that
Many of these hormones are natural and are completely necessary for proper functioning of the metabolic systems. Others, however, are administered artificially to stimulate growth or to increase strength and energy, legally or illegally. Anabolic steroids, for example, are used therapeutically to treat a variety of different conditions, such as delayed puberty. They increase muscle growth and are closely related to testosterone, so they stimulate many other masculine features such as voice depth and hair growth. Some anabolic hormones include
The endocrine system in the human body stores a chemical known as hormones. Hormones are released by endocrine glands into the bloodstream and travel throughout the body carrying messages. A hormonal impulse is similar to a nerve impulse only much slower. The messages carried by the hormones trigger different behaviors. Hormones can affect behavior in many ways such as: Mental activity or tiredness, boredom or excitement, sexual
