Body builders are often tempted by the fact that there are injections and pills that will help ease their workout by a substantial amount. A type of steroid that is very powerful and legal is Permadrol. Permadrol blocks sex hormone binding globulen and aromatase enzyme to help increase the free levels of testosterone flowing through the body helping to build more muscle and strength. A benefit of Permadrol is that it is legal, affordable, and contains naturally occurring substances. However, the drawback of Permadrol is that it is not FDA approve meaning that there are side effects and is not 100% safe for the human body. Some side effects include nausea, loss of appetite, and depression.

Guarana (also known as Paullinia cupana, paullinia, Brazilian cocoa, guarana bread, guarana paste or gum, and zoom) is an herbal supplement that is used as a stimulant and appetite suppresant. It is an ingredient that is used in sweetened or carbonated drinks; Many yo-yo dieters may turn to this herbal remedy to control food cravings (and to control weight), whereas those who are looking for a quick burst of energy might use it to become alert, since it is high in caffeine concentration. Because Guarana is chemically equivalent to caffeine, studies show that it is supposed to increase memory, mood, and alertness levels, but this has not been confirmed. Guarana has not been evaluated by the FDA, so all the risks associated with this herb are not known. Some of the risks are irregular heartbeats, chest pain, heartburn, upset stomach, loss of appetite, constipation ,diarrhea, nervousness, irritability, anxiety, sleeplessness or headache.

A type of supplement is a botanical which is a plant that is valued for its medicinal purposes. Products made from botanicals are used to maintain or even improve health, these are called herbal products, or botanical products. Many of the definitions of a supplement are standard under the botanical.
The botanical is a type of standard supplement in that the action of the botanicals range from mild to very potent. There are subtle effects if the botanical has mild action. Like chamomile and peppermint, both mild ones, are usually taken as teas or used to help with digestion. Some take days before actually showing results. Whereas, a powerful botanical such as Kava produces a fast result that affects anxiety and muscle relaxation.

I did a little research on muscle fiber types and exercise techniques, and I came across this website. It explains how Type A is the primary force generator and to get maximum performance from them, you should try sprinting at full speed or trying any type of plyometric activities. For Type B training, you need to simultaneously decrease your force of contraction and increase the time of contraction very slightly. Also, endurance will definitely improve your slow twitch muscle fibers, so you need to focus on lasting longer whenever you exercise. Thinking about these various muscle types will help you achieve your training goals much more effectively.

I found this website to be very helpful with different types of muscle fibers and training. It is written by Jason R. Karp who is currently pursuing his Ph.D. in exercise physiology at the University of New Mexico. It summarizes everything we have learned in class and gives a chart similar to what we completed in class. It also goes more in detail about recruiting and implementing of different muscle types for various types of training.
I was very interested in the temptation of blood doping in sports, so I researched it further. I found out that there are two methods of blood doping through blood transfusions.
One of these methods is autologous. With this form, the athlete donates blood, stores it and returns it to themselves at a later point in time. This form of blood doping has a few advantages including the avoidance of diseases like Hepatitis and HIV, as well as removal of other potentially harmful transfusion reactions.
The other method is homologous. In this method, another person's blood of a certain type is given to a person with that same type. This gives them extra blood in their system, allowing for more oxygen to come in and better performance.
The problems with these two types of doping are that with autologous doping, it would be hard to train while having to donate enough blood to make the performance better because it takes time for the body to recover after blood is removed.
Homologous doping doesn't suffer from this problem, but users gain a higher risk for getting blood born diseases. The risk of transfusion reactions also rises. Also, there is increased transfusion sensitivity.

It was stated in class that every individual possesses different muscle fiber types in their body. Looking at the sprinter and marathon runner’s pictures, its seemed as if every muscle in Leonard Scott had more Type 1 fibers than Isegwe’s muscles. Although this might be the case, in general a person cannot simply be categorized as having more Type 1 fibers than Type 2, and vise versa. This is because every type of muscle in the body is different and has a different tolerance to exercise. Body builders tend to face a dilemma when they first start training since they assume if they constantly lift weights, their muscle mass will increase in every part of their body. However, more experienced body builders over time analyze each individual muscle and come up with a different plan for each in order to gain the maximum muscle mass potential for each. Thus, even with body builders, simply applying weight to every part of the body will not necessarily maximize the amount of their muscle mass.
I decided to research muscle milk since many of my housemates have used it in order to gain more mass and weight. It contains whey and caseins, muscle milk is made mimicking human mother's milk, which has important anabolic growth potentials. It is said to be a good protein drink before sleeping. Another website said muscle milk's problem is with the substance glycocyamine, it is known to increase our blood levels of homocysteine, which is thought to be a risk factor for cardiovascular disease.

This article has a similar chart to the one we created in class. This article explains that the muscle fiber type cannot be changed unless the neuron connecting to that fiber is changed. The article gives advice for coaches to determine athletes workout routines depending on their more prominent muscle fiber type. One example, is that the a coach should consider giving and athletes who fatigue quickly (due to more type IIb fibers) more time to rest between endurance training, as well as making sure that athletes with more prominent type I muscle fibers are given less repetitions to complete in strength training. The article says that although the muscle fiber type cannot be changed, they can be influences by the type of training conducted.
I found the website that explains about muscle fiber types and training. Type 1 muscle fiber is slow oxidative type that gets ATP from cellular respiration. It is also known as slow twitch muscle. The negative about this muscle fiber is low ability to produce power. Type 2a is fast glycolytic. It is fast twitch muscle that much faster and stronger than type 1 muscle fiber. Type 2b is important muscle fiber in our body. It is an emergency muscle fiber that brings instant power and strength to survive the situation.
There are generally three major endurance training. The lower repetitions like 3-8 makes productive for creating absolute strength, medium range repetitions like 10-20 produce anaerobic strength endurance and high repetition 20-40 ranges produce aerobic strength endurance.

I was very curious learning about the benefits and the side effects of taking creatine to build muscles, and get stronger. My curiosity actually started when I noticed a friend of mine taking creatine supplements to grow more muscles and get bigger.
After my research I find that, there hasn't been much studies done on it to prove a definite pro and con of this product. So as we learned in class, creatine is a natural compound used by our muscles to create ATP. The job of a creatine supplement would be to increase the production of ATP in the muscles to provide longer strength in a workout.
In order to creatine phosphate the pros and cons need to be weighed out.
Pros of this product is of course the increase in energy, better muscular performance, weight gain, stronger muscles.
Normally if our diet includes a good amount of meat, it means that we are getting a very small dosage of creatine supplied to our body. However by taking a creatine supplement, supplying a large dosage of creatine to our body raises questions of the possible problems in our organs and muscles.
I hope more research gets done on this product so if it does turn out to be harmful, people can learn sooner to stop taking it.
