Web Calculater Exercise 2 Essay

The range of normal resting diastolic BP for these patients was 75-85 mmHg. Did diastolic BP increase, decrease, or not change with exercise?

The effects of heart rate on differing durations of exercise were studied in this experiment. For people, heart rate tends to increase as they perform physical exercises. The amount of beats per minute gradually increases as people perform physical activities. Heart rates taken before exercise are relatively low, and heart rates taken one minute after exercise increase significantly. Heart rates slowly begin to decrease after they are taken two minutes and three minutes after performing the step test, which is to be expected. The rates of intensity throughout exercise relates with changes in heart rate throughout the step test performed in the experiment (Karvonen 2012). The age of the participants affected the experiment, since the heart rate during physical exercise, in this case the step test, is affected by age (Tulppo 1998).

At one school, the average amount of time that tenth-graders spend watching television each week is 18.4 hours. The principal introduces a campaign to encourage the students to watch less television. One year later, the principal wants to perform a hypothesis test to determine whether the average amount of time spent watching television per week has decreased. Formulate the null and alternative hypotheses for the study described.

The hypothesis testing process begins by forming a question about the topic at hand. In this case, “Does listening to music while doing math stimulate a certain region of the brain that is not affected when doing math without music?” This question is then turned into a pair of

Being knowledgeable about the heart is very important, especially if one is an athlete. This experiment is significant, because it can tell us how important it is for one to keep their heart healthy. It will also tell us how playing a sport can benefit one’s health and the well being of their heart. Our hypothesis says, if the athleticism of a person increases, then the heart rate recovery time will decrease when heart rate recovery in a function of athleticism. The purpose of this project is to see which type of athlete, or non-athlete has the best heart function.

I decided to choose the sprint test for my client Reece is because my client plays basketball at a performance level, in such a sport acceleration is very important this is because player have to be quick on their feet for fast breaks, getting back on defence and outwitting an opponent. Most running is conducted over a short distance. The reason why I also picked the sprint test is because he also does athletics the reason why he also needs this trait is because Athletes who can move faster than their opponents have an advantage. For example, a faster athlete may be able to finish the race at a faster time. This test is carried out in a number of stages which are a properly carried out warm up, a partner to measure 35 metres preferably with cones the athlete should then get into sprinting position and when the partner yells go the athlete would then go on to running 35 meters this test would need to be carried out 3 times it is acceptable if a break is taken

My client performed the Arm Curl, Chair Stand, Push Up, Standing Heel Raise, Unilateral Step Down, Single Leg Stance Eyes Open, Single Leg Stance Eye Closed, Standing Stroke, Four Square Step, Time Up and Go, Four Meter Walk Velocity, and Two-Minute Walk Test. He scored 28 reps in 30 seconds for the Arm Curl Test. In the Chair Stand Test he recorded 50 reps. In the Push Up Test he was able to do 31 reps. In the Standing Heel Raise Test he was able to do 31 reps for the left foot and 32 reps for the right foot. In the Single Leg Stance Test with eyes open he recorded 90 seconds on both legs. With eyes closed he recorded 9 seconds on his left leg and 8 seconds on his right leg. In the Standing Stroke he got 3 seconds for both right and left legs. For the Four Square Step Test he had three trials. He finished in a time of 4 seconds for one, 3.9 seconds for the other and had 1 miss trial. In the Time Up and Go test he completed it in 3.8 seconds. For the 4-Meter Walk Velocity Test he completed it in 1.72 seconds and had a speed of 2.33m/s. In the 2-Minute march test he completed 92 reps.

This experiment will involve five individuals putting their left hand in different samples of water of varying temperatures. Their blood pressure and heart rate will be recorded before the experiment, and after each water trial, to determine the effect it has on both the blood pressure and heart rate.

In week Twalef, I learned the hypothesis currently believed to be true. I found Any times when I see the alternative hypothesis written with a not equal sign, this means we are going to perform a two-tailed test. Also, I learned about the sampling. We have to consider that we took a sample, and so there is the risk of sampling error. Random sampling even true of the sampling frame can produce representative samples from time to time. That's when figures from our sample shows the difference between the two groups (between the sexes, perhaps, or between adults and young people), and this may represent a real difference between these groups in the population, but the product may be just taking a sampling error.

In this experiment there were 106 student’s participants. 57 students took the caffeinated (Group A) coffee and 49 of them drank the decaffeinated coffee (Group B). The mean different in resting pulse rate (pre-treatment) between both group A and B is 2.6 beat per minute). The mean different in resting pulse rate (post-treatment) between both group A and B is 0.9 beat per minute. Which show no significant difference.

For persons 1-3, as predicted, the heartrate and breathing rate were relatively low with Person 1, respectively, being 74 & 20, Person 2 being 86 & 16 and Person 3 being 73 and 19. The 50m Sprint resulted in having the highest heartrate for persons 1 and 2, 152 and 171 respectively, and the Stairs resulted in being the highest for Person 2 at 130. Strangely, the breaths per minute for persons 1 and 2 were highest, at 40 and 39 respectively, whereas Person 3 experienced their highest breaths at 43 for the 50m Sprint, which coincides with their highest heart rate. These trends show that the hypothesis is correct in the sense that the heart and breathing rate did increase with physical exercise, however, the hypothesised theory that the Sprint

There were 12 subjects, but one withdrew from the experiment due to stomach problems. The 11 participants are male, age between 25-37 years old, no height represented, weighing between 76-88 kg and the participant was a cyclist or athlete. Each participant went to the laboratory 6 different times. The first visit of the experiment was to let the participant do a cycle ergometer test for exhaustion. After the first visit, the participant had to do 2 more visits

The purpose of this lab is to test the effect of exercise on heart rate. Each participant will take their pulse at the neck for 10 seconds, and multiply it by 6. Each participant will run around the building once. Immediately after running, the timer will start for 3 minutes until running is done again, and each participant

The purpose of the experiment is to see how different variables affect pulse rate and blood pressure.

Carry out an experiment to measure the heart rate and ventilation rate before, during and after moderate exercise.
