An Laboratory Three Submaximal Tests Were Done The Highest Heart Rate And At What Times?

Six different subjects all between the age of 21-25 from all different physical levels performed four experiments. Each experiment consisted of two sessions a warm-up and lifting both a 10 lbs and 15 lbs dumbbell with a two-minute break between the two loads. The warm-ups were bicep stretches, which involve three different stretches and lasted for about 30 seconds each for a two-minute stretch, cardio, which included step up until max heart rate was

Introduction: In this experiment, cardiovascular fitness is being determined by measuring how long it takes for the test subjects' to return to their resting heart rate. Cardiovascular fitness is the ability to "transport and use oxygen while exercising" (Dale 2015). Cardiovascular fitness utilizes the "heart, lungs, muscles, and blood working together" while exercising (Dale 2015). It is also how well your body can last during moderate to high intensity cardio for long periods of time (Waehner 2016). The hypothesis is that people who exercise for three or more days will return to their resting heart rate much faster than people who only exercise for less than three days.

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

This experiment was carried out as noted about in Procedure 1. The resting heart rate was established and used as a baseline value from which to compare all future deviations. While data could

A heart rate monitor could have been used instead of the manual method, which would produce a more accurate result of the heart rate measurement. (http://www.topendsports.com/testing/heart-rate-measure.htm).

The range of normal resting systolic BP for the subjects in this experiment is 115-125 mmHg. Did systolic BP increase, decrease, or not change with exercise?

7. After obtaining 10-20 seconds of stable heart rate values, rise rapidly to a standing position. Continue to record until the baseline heart rate has been achieved or until the end of the run. Data will be collected for 400 seconds.

The heart rates of participants was tested before the step test, one minute, two minutes, and three minutes after the step test was performed in this experiment. Since heart rate increases while someone is performing physical activity, it was expected that heart rates of the students would be higher than before the step

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.

The controlled variable included the exercise bike and heart rate monitor. There are several limitations, systematic and random errors that should be considered when interpreting these results. (4) The controlled variables were not tested before this experiment to see if they were working and reliable. Figure 2 heart rate was quite inconsistent and did not follow the pattern of the other results, which maybe suggest a random error with the heat rate monitor. A systematic error could include the fitness of the participants. One of the test subjects is an endurance athlete and the other does not compete in any sport. This would affect the results because for the endurance-trained athlete, from their training they increase their cardiac output results from a substantial increase in maximal stroke volume. In untrained persons, cardiac output increases in response to exercise primarily by an increase in heart rate. The endurance-trained athlete does so mainly by an increase in stroke volume. Simply meaning that although both participants are doing the same cadence and length the endurance athletes skewers the results by already having an increased rate in stroke volume. Another systematic error may include the rate of perceived effort. For the most accurate results, the measured maximum heart rate would be necessary to give an accurate cadence to ride at.

As with the previous two phases the athlete will undergo another series of assessments. This time however the assessments will be different. Whereas before we were looking at areas of explosive strength in sprinting and weighted exercises, this time the emphasis will be placed on cardiovascular endurance. The assessment we will be primarily focused on will be a 1.5 mile run for time and heart rate. The reason we are focused on heart rate is to find his optimal heart rate for prolonged distance. Using a heart monitor we will have him preform the test three time and average of the three heart rates will be the target number. He will of course be allowed a 10 beats per minute cushion to allow for factors that are beyond our control like atmospheric issues such as heat and humidity, and any delayed onset muscle soreness(fitnessschoolbook). Again once all the data has been analyzed we will begin the last phase of the training regime.

Research Question: What is the effect of practicing aerobic sports on a daily basis, on the recovery heart rate of people?

The results of this test show that it provides a valid test to estimate aerobic capacity and shows there is a small measurement of error. A polar heart rate monitor was used to measure the heart rate with a step of 30cm in height with a metronome with a beat at 15 steps, per minute and increased by 5 steps every minute for 5 stages or until 80% of the maximum estimated heart rate was reached. The results demonstrated that the Chester Step technique is a valid predictor of aerobic capacity in males and females from a wide range of ages and fitness levels.

As the intensity of exercise increased, so did the rates of the heart and breathing. After a small period of rest, the heart rate and breathing rate both decreased to a point close to their resting rate. This proved the stated hypothesis. First, the hearts average resting rate was recorded to be 76 bpm. The heart is therefore transporting oxygen and removing carbon dioxide at a reasonably steady rate via the blood. During the low intensity exercise (Slow 20) the heart rate increases to 107 bpm, which further increases to 130bpm at a higher intensity level (Fast 20). The heart therefore needs to beat faster to increase the speed at which oxygen is carried to the cells and the rate at which carbon dioxide is taken away by the blood.

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