Stress Using Rats

In a laboratory study of sleep deprivation, researchers employed a variety of techniques to keep

Since 1990s, many scientists agree that exercise has positive impacts on people’s physical health and mental health (SIME WE, 1987). From Morgan and O’Connor’s research, people can reduce stress and state anxiety by doing physical activities; also gain emotional pleasure from the process (Morgan and O’Connor, 1988). Later in 1997, Landers states that physical activities can reduce people depression after weeks of regular and routine exercise. In addition, people can benefit from more

Our experiment was performed in the Science and Technology build on the USCB Bluffton Campus on October 6th from 4:30 to 5:30 p.m. In order to construct the study for this experiment, we divided the actual experiment work in order to be able to complete the study for all sixteen (16) subjects within the given time period available to accommodate the test subjects. The experiments was conducted in the hallway, during the process we tested three participants at a time. We constructed an informational form regarding gender, age, weight amount of exercise per week. The supplies needed were approximately 25 test participants for the class, informational form, a blood pressure reader, timer, 15 jumping jacks, three chairs, paper and pencil to record

In the first experimental session, subjects will be randomly assigned to receive either a low or high GI food prior to exercise, then carry out the experiment in the second session under the alternate condition.

The independent variable in this experiment was whether the rat was raised in isolation with no toys or in group with toys and which cage they were tested in whether it was the home cage or a new cage. The dependent variable was how many times rats in each scenario stuck their noses in the candles flame. Results showed that almost every rat stuck their nose into the flame in pure curiosity however, rats raised in a restricted environment and placed in a new environment stuck their noses in almost double the amount of times than any other rat did. These results indicate that rats raised in isolation handle stress differently and that those in isolation have poor pain avoidance. I liked this study because it shows that curiosity is prominent in rats as in humans although it only takes us one time to realize something hurts to not do it again. It also shows that something raised in isolation reacts to stress in a negative way and proceeds to harm themselves and with this evidence we can maybe understand why depression can lead to

Stress is an ambivalent concept. It applies to many different phenomena and eludes precise meaning. Stress may have different meanings for each individual, and even scientists have widely varying definitions of it. For example, Selye (1973) specify “stress as a functions of elevated corticosteroid levels and uses the term to refer to the effects of any agent to that threatens stability of the organisms”. Cannon (1935) used the term stability to deal with to the “process of keeping internal balance in the face of environmental change”. Cannon argued that human beings can responds to deviations from normal conditions by invoking behavioral changes, thus modify metabolic and other bodily processes to re-achieve optimal conditions. Selye introduced

The subjects were Sprague-Dawley male rats. Their age is 150 days. The supplier is Harlan Sprague-Dawley. They are maintained on a 12:12 h light/dark cycle and are provided with ad libitum access to food.

Once those conditions are set, the baseline thresholds for the rats are determined. For eight days, the

The researchers conducted a sham surgery on the control group, so the control group would undergo the same amount of stress as the experimental group. The researcher did not want the surgery on the experimental alligators to be another variable in the experiment to conflict with acid secretion in the alligators’ digestive system.

In this experimental lab, I previously stated that I would observe the participants and their heart rates in their stationed environment. The results of the lab concluded as we successfully predicted. The environment individuals surround themselves does impact heart rate. Participants in the study who were placed in the control environment showed an average heart rate of 60-70 bpm. The participants in the study who were placed in the experimental group showed an increase in heart rate of about 105-125 bpm. All 100 participants completed the study and received their rewards. None of the participants had any problems with their health after the study was completed.

This paper will present studies indicating the affect exercise has on the human body and how it is useful in keeping us at our optimum physical and mental health. For now, aging is inevitable. Physiologically, we age because individual cells are preprogrammed to overwork and then

For centuries exercise has been a part of the lives of men. Whether through carrying a freshly hunted boar through the forest or riding a bicycle to work, exercise plays a huge role in a vast amount of areas. As man learned more about the body and how everything functioned, he uncovered how many factors play a role in health, including mental health. Doctors normally recommend daily exercise. However, there are other sides of the argument. One can become addicted to exercise. The addiction starts as a mental need but can eventually result in a physical dependence. The effects of this on the body are still unknown and being examined. Even less known are the effects it has on the brain: the center of human activity and intelligence. One would want to do everything in order to preserve and improve cognitive abilities. It seems survival of the fittest is now a matter of neurological and cognitive capacities rather than physical attributes as it once was. Therefore, the question must be asked what effect exercise, a major aspect of human life, has on the brain.

d. Subjects are randomly assigned to four groups. Each group is placed on one of four special diets—a low-fat diet, a high-fish diet, a combination of low-fat diet and high-fish diet, and a regular diet. After 6 months, the blood pressures of the groups are compared to see if diet has any effect on blood pressure.

Stress is one of the many causes, as well as a symptom of depression. According to Brosse (2002), sustained or chronic strain contributes to an increase in the release of hormones such as cortisol, an anxiety hormone and reduced serotonin and neurotransmitters in the brain, which is associated with depression. Depressed people have a reduced capacity to experience euphoric moments, which is a distinguishing symptom of clinical depression. Evidence from different studies indicate that exercise has a significant impact on reducing stress among depressed people by providing a distraction from stressful situations or thoughts (Palmer et al., 2005 & Brosse et al., 2002). Constant worrying about stressors in the patients’ lives leads to anxiety and amplifies depression. During exercise, a patient’s mind has a chance to forget all the cares and worries that trouble their thinking and focuses on the exercise task. The exercise allows patients to take a break and enjoy some activities that restore humor and fun in their lives. Tkachuk and Martin (1999) claim that constant worrying among humans facilitates the cycle of anxiety and depression. In a study reviewing systematic research Perraton, Kumar and Machotka (2010) state that aerobic exercises such as yoga, Pilates, Tai Chi and anaerobic training including machine-based resistance and standing exercises, keep the patients occupied and reduces the stressors. Further, in the study, Wipfli, Landers, Nagoshi, and Ringenbach (2009)

Many young adults within the university and college educational system experience stress. The stress and anxiety they incur can vary due to multiple factors. This chapter examined some of these different factors and how they have contributed to undergraduate student stress and anxiety and overall college experience. It also focused on the positive and negative coping mechanisms students utilized in order to manage their stress and anxiety. Finally, it examined the mental health resources available that have helped promote adaptive emotional management skills. By examining these factors the reader will better understand the elements that could contribute to the student’s ability to thrive in their undergraduate experience.
