Determining the Effect of Arousal on the Heart Rate and Blood Pressure of Adolescent Males
Determining the Effect of Arousal on the Heart Rate and Blood Pressure of Adolescent Males

ABSTRACT
When male adolescents were unknowingly placed in an isolated environment with an attractive woman, there wasn’t enough viable data to determine whether or not their blood pressure increased. Based on our limited and unreliable data there is no significant increase in the heart rate or blood pressure of male adolescents when placed in this situation.
INTRODUCTION
As blood flows through all parts of the body, it exerts a pressure on the walls of the arteries carrying it. Blood pressure reflects this force through two numbers, the systolic and the diastolic. The systolic measures the pressure when the heart muscle contracts and the heart beats, while the diastolic measures the pressure when the heart muscle is at rest between beats. Blood pressure is influenced by many factors including the pumping action of the heart, volume and thickness of blood, and its resistance to flow (Factors.. ND). There are many other aspects, however, that have the capability to hamper these processes; as is the case with various stressors. In our experiment, we hoped to observe a significantly (P<0.05) higher blood pressure in adolescent males exposed to a one- on-one experience taking blood pressure readings with an “attractive” woman compared to that of an experience with detached and less involved facilitators. We hypothesized such an observation would be possible because of the nature of initial attraction on the body. Initial attraction stimulates the same reaction from the body as fear (“High on Love” ND). When stimulated, the hypothalamus, a tiny region of the brain, sets off an alarm system in your body that prompts your adrenal glands to release a flow of hormones, including epinephrine (“Stress” 10). Epinephrine, or adrenaline, affects the arteries as it acts upon the adrenergic receptors

    As stated in the study the subjects were placed in a room with a certain temperature and that was away from noise of the clinic. The subject then took off any constrictive clothing and was seated to relax for a minimum of five minutes. With the participants feet flat on the floor the blood pressure reading was obtained and recorded. After a minimum of three minutes the subject was told to cross one leg over the knee of the other leg and the blood pressure was then measured and recorded again (Foster-Fitzpatrick, Ortiz, Sibilano, Marcantonio & Braun, 1999).…

    The effect of exercise/physical activity on pulse, blood pressure, and respiration rate was tested on biology students. The results of the experiment showed that each of these parameters is affected after engaging in 2 minutes of physical activity. We found that average pulse, mean arterial pressure, and respiratory rate were all higher in males than in females. But, it was also found that women have a longer time to recovery for all these parameters. The reasons for higher pulse, MAP and blood pressure, and respiratory rate could be because on average men have an overall higher normal blood pressure than women. Also, I would assume that a reason women have a longer recovery time than men could be due to hormonal differences. Factors not recorded that could have affected outcomes of the experiment could be that the sample size and distribution, human error of calculation, and mechanical error.…

    Sad ratings are most strongly associated with changes in heart rate, blood pressure, and skin conductance and temperature. The fear ratings were associated with changes in the rate and amplitude of blood flow. The happy ratings are associated with changes in respiration measures. The correlations are fairly low, however. A limiting factor may have been characteristic response times and lags of physiological systems. The general difficulty of identifying emotion- specific changes in these psychophysiological measures should also be noted. Physiological changes depended on the amount and type of musical emotion. The degree of correspondence depended on the emotion-eliciting…

    The autonomic nervous system controls the heart and has two branches; the sympathetic nervous system and the parasympathetic nervous system. When the body is undergoing muscular work, fear or stress the sympathetic nervous system will be active. When the sympathetic nervous system is active it will cause every heartbeat to increase in strength and heart rate. During resting, peace and contentment the parasympathetic nervous system is active and it calms the heart output. During periods of fright, flight and fight the sympathetic nervous system is boosted by the hormone; adrenaline. The nerves of the adrenaline are the cardiac nerves. A special cluster…

    Adrenalin is a hormone secreted by the adrenal glands that helps the body deal with stress. It produces the emergency, or "fight or fight," response and is secreted when sudden stress such as fear, pain, anger, or extreme physical exertion requires a burst of energy. Adrenalin causes increases in metabolic rate, breathing rate, heart rate, blood pressure, sweating and even blood clotting. It is a convenient hormone to study because its effect is relatively swift.…

    According to Cannon’s theory physiological arousal is merely an indication that the organism is ready or prepared for an emergency response, such as fighting or fleeing. When a person jumps from a high level, they tend to get their bodies ready for when they reach the ground. Not only does the individual get ready to land properly, their bodies set themselves up to the proper way to jump. According to Cannon (1927, 1929/1953) these emergency responses make the organism more capable in dealing with situations that produce fear, rage, and pain. These states are felt as urges and impulses to act in a certain fashion depending on the emotional experience. Thus, when frustrated a person may have an urge to yell insults or when in love a person may have the impulse to touch another person. Emotions and action readiness are linked together (Cannon, 1929/1953).…

    When working with human subject, many considerations need to be taken, firstly the age of the subject. Marieb et al. outlines, ‘foetuses have a higher blood pressure than that of an adult’. Sex is also another factor that determine heart rate. Females usually have a higher heart rate (72-80beats/min), than that of a male (64-72beats/min). Medical history and cultural background. If a person suffers from cardiovascular disease known as tachycardia, they would have an abnormally fast heart rate, while subjecting suffering from bradycardia, would have the opposite effect. Body temperature can also contribute towards an increase or a decrease…

    Cardiovascular Dynamics and the Cardiovascular Physiology experiments both have multiple goals. The first experiment aims to understand how blood flow, pressure gradient, and resistance relate to one another. To understand this, resistance and contributing factors, such as vessel radius, viscosity, and vessel length must be studied. The effects of vessel radius and stroke volume on the ventricular pump should also examined. The experiment also calls for an understanding of cardiovascular compensation. Pump mechanics are further understood through a design of further experiments. The Cardiovascular Physiology experiment attempts to understand the effects of parasympathetic and sympathetic nervous systems on the heart, through vagus nerve stimulation. Refractory periods and relative refractory periods will be studied in direct stimulations of the heart, as well as the five phases of the cardiac cycle. Lastly, the effects of temperature, hormones, and ions will be understood. Epinephrine, pilocarpine, atropine and digitalis are the hormones used to modify the heart. Sodium, potassium and calcium are the ions used in this experiment.…
