Answer Key for 'Lewis and Clark Reloaded'

1. Recall that Jim's heart and respiratory rate are increased, he was sweating and that his mouth was dry before the raise began. Explain what is happening to his autonomic nervous system (including which division is the most active) and specify exactly how those ANS responses are creating the symptoms noted. What changes do you think are occurring in the digestive and urinary systems at this time? (8 points)

In this assignment I will be reviewing the different effects of exercise on the body system including the acute and long term using the pre-exercise, exercise and post-exercise physiological data which I collected based on interval and continuous training method. I will also be including the advantages and disadvantages of these, also the participants’ strengths and areas where they can improve on.

1. During exercise: TV will increase. 2. During exercise: IRV will decrease. 3. During exercise: ERV will increase. 4. During exercise: VC will not change. 5. During exercise: TLC will not change.

Four interval times (PR, RT, TP and RR) measured in seconds were recorded both with the subject at rest and after the subject had exercised. The PR and RT intervals remained virtually unchanged with the PR intervals remaining the same both before and after exercise with an interval time of 0.15 seconds, and the RT interval increase by 0.01 seconds from 0.37 at rest to 0.38 seconds after exercise. More substantial changes were noted in TP and RR intervals. The TP interval decreasing from 0.32 seconds at rest to just 0.08 seconds after exercise, a decrease of 0.24 seconds (just 25% of the resting 0.32 seconds). The RR interval decreased from 0.84 seconds at rest to 0.61 seconds seconds after exercise, a decrease of 0.23 seconds

An independent samples t-test was conducted to examine the difference between experimental conditions on test performance. The results indicated a significant difference between participants who consumed the caffeinated beverage and participants who did not, with participants in the caffeinated group (M = 7.64, SD = 2.41) performing worse than participants in the non-caffeinated group (M = 9.81, SD = 3.16), t (97) = 2.14, p < .05.

Introduction: (bring a monster, sip it) alright. How many of you here drink coffee, energy drinks, or soda daily? Well we aren’t alone; according to Villanova Health Service about 90 percent of Americans consume caffeine in one way or another every single day.

To maintain effectiveness of muscle and bone activity, the effects of on the musculoskeletal system are the greatest benefits a person can ask for.

III. “The U.S. Food and Drug Administration (FDA) and the American Medical Association (AMA) have estimated that the average daily caffeine

In this situation the sympathetic nervous system (SNS) would dominate the parasympathetic system due to the vigorous physical activity that would be required, and the boost in ATP (Adenosine Triphosphate). This system allows the individual to reduce bodily functions require high amounts of energy such as the gastrointestinal tract, the system relaxes the muscles along the track and diverts the energy. It also has a long lasting effect as the axons that are activated in this system as they have the ability to activate many tissue simultaneously. http://medical-dictionary.thefreedictionary.com/general+adaptation+syndrome

Treatment with water, caffeine, alcohol, and gatorade and the effects on urine output, pH, Na+ excretion, and solid excretion were tested at 30 minute intervals for 2 hours. It was found that urine production for each treatment group increased after 30 minutes, increased further after 60 minutes, and then began to decrease. Mean increases in urine production were only significant for Gatorade in the first 90 minutes (an increase of 40% at 30-60 minutes, and a decrease of 73% at 60-90 minutes) and for caffeine over 60-90min (a 48% decrease). The average pH for each treatment group became more acidic by 90-120 minutes. Mean differences over each time

Thesis: Caffeine can have many different effects on the body depending on the amount of consumption.

This experiment tested the hypothesis that there was no difference between cellular respiration before vigorous exercise and cellular respiration after vigorous exercise in terms of rate of cellular respiration.

One on the beneficial effects on caffeine, two the negative effects, and finally on trends in caffeine consumption

Thesis: Caffeine is something that almost everyone has consumed and some people are even addicted to. Caffeine has negative and positive effects on one’s health

Just like how modern technology has been embedded into lives of students, caffeine has become a necessity in student’s daily life as well. The workload of a college student can be overwhelming and it drives students to rely on caffeine. When they rely on caffeine for their body to function, they overlook an important aspect of their health conditions which is the absence of sleep. Students can be at risk for consuming too much caffeine especially when now a days, students lose track of their daily intake. Although there are beneficial aspect of caffeine that offer students to be at their optimal performance in their daily task.
