Although stimulants can improve physical performance and increase aggression on the field, they also have side effects that can hinder athletic performance, such as anxiousness and impatience, which make it difficult to focus on the game. Insomnia can make it difficult for an athlete to get enough sleep. Stimulant abuse may lead to mood changes, irritability, and increased violence toward others.
Anabolic steroids are chemical compounds derived from testosterone. They work by binding to receptors in cells, causing them to produce more of the hormone than normal. Anabolic steroids have many different uses, including treatment of cancer, chronic fatigue syndrome, and depression. However, they can also be used by athletes to build muscle and strength faster. Because these drugs affect the body's natural production of testosterone, users must regularly take the drug and supplement their diet with proteins and carbs to keep their levels high enough for effective use.
Ephedra is a plant found in north-western America that has been used for its medicinal properties since early times. The most well-known active ingredient in ephedra is ephedrine, which can be used to treat asthma, allergies, and other respiratory conditions. Ephedrine stimulates alpha-adrenergic receptors in the brain and body, producing effects similar to caffeine but without the jitters or anxiety associated with coffee. A number of recent studies have shown ephedra to be an effective fat burner, helping people lose weight by breaking down stored fats in the body.
Stimulants are used to improve performance in sports. These chemicals stimulate the central nervous system, increasing alertness, focus, metabolic rate, power, and strength while decreasing weariness. Stimulants can also act as diuretics, helping a person to lose weight by making them more aware of their body temperature and resulting urine output.
Stimulants are often used by athletes before important competitions to boost their energy levels and reduce their physical and mental fatigue. The use of stimulants during exercise is known as "stimming."
Some common examples of stimulants include caffeine, theobromine (found in chocolate), amphetamines (such as Adderall and Ritalin), and ephedrine/methamphetamines (such as those found in weight-loss products). Caffeine is found in many beverages and foods, including coffee, tea, cola, chocolate, etc. Theobromine is found in dark chocolate and cocoa powder. Amphetamines increase the amount of dopamine in the brain and are usually used to treat disorders associated with low levels of dopamine production such as Parkinson's disease and Huntington's disease. Ephedrine increases the level of adrenaline in the body and is commonly found in diet pills and weight-loss products.
Stimulants are used by certain sportsmen to excite the central nervous system and raise heart rate and blood pressure. Stimulants can help with endurance. Reduce tiredness. Increase reaction time.
Stimulants include caffeine, amphetamines (such as Adderall or Dexedrine), ephedra, guarana, ginseng, herbal products such as yohimbine and ma huang, and methylphenidate (Ritalin). In some cases, doctors may prescribe them for athletes who need extra energy or focus during a competitive period.
Stimulants can be harmful if used regularly or in excess of what is recommended. Too much caffeine may cause jitteriness and irritability. Amphetamines are known toxins. Herbs such as ephedra contain chemicals that can cause heart failure if taken in large quantities. Methylphenidate can have side effects including nausea, stomach pain, diarrhea, headache, depression, anxiety, mood changes, trouble sleeping, tachycardia (fast heartbeat), hypertension (high blood pressure). It is important not to take more than the recommended dose of any medication without first talking to your doctor.
Stimulants are banned from most sports because they can be harmful if used at high levels or for long periods of time.
Stress induces attentional alterations (such as narrowing of attention, general distraction, greater self-awareness, and mental exhaustion) that impair athletic performance. Stress has been demonstrated to increase muscular tension and coordination problems, increasing the athlete's risk of injury. Stress also affects the immune system, increasing one's chance of contracting a virus or bacteria which can then lead to illness. Stress hormones such as cortisol are known to decrease bone density, potentially increasing an individual's chance of suffering from osteoporosis later in life.
The most important factor in preventing injuries is to avoid becoming too stressed out. Too much stress can be as harmful as not enough, and it is important to find a reasonable level of stress at which you can operate without being injured. Multitasking - doing more than one thing at a time - is difficult to do effectively while still maintaining good form and control over your actions. For this reason, many people who suffer from stress tend to push themselves too hard and become injured as a result.
Another factor that may cause an athlete to injure himself/herself is lack of sleep. Sleep is important for healing both physically and mentally, and poor sleep habits can lead to irritability, anxiety, and other negative emotions that can cause someone to make mistakes during exercise or play sports games excessively hard. Going without sleep for several days may even cause someone to die!
It may discover that certain athletes have tested positive when they are not. Some prominent athletes who were disqualified for drug usage were using something seemingly harmless, such as cough medication, without understanding it contained a forbidden substance.
Athletes take illegal medications to boost alertness, competitiveness, responsiveness, and weight reduction. Addiction, hostility, anxiety, hypertension, brain hemorrhage, coma, convulsions, dehydration, heart attacks, sleeplessness, strokes, tremors, and even death are all possible adverse effects of the medicines.
