Internal Assessment The relationship between recovery heart rate between athletes and non-athletes Lab Design: Research Question: What is the effect of practicing aerobic sports on a daily basis, on the recovery heart rate of people? Hypothesis: If a person practices an aerobic sport on a daily basis (athlete), then he will have a higher recovery rate due to the fact that their hearts are more accustomed to intense physical exercises than someone who does not (non-athlete). Background info: Heart Rate Recovery • The rate at which your heart returns to a normal resting rate after physical activity is known as the recovery rate. • The rate is usually a reliable indicator of your cardiovascular fitness. • Typically, athletes have a faster recovery rate than non-athletes because their hearts are trained and accustomed to intense physical exertion. o An athlete's normal resting rate may hover around 40 beats per minute once he has recovered from exercise. Average heart rate • Eighteen years old (boys) - 70 beats/min (can range from 50 to 90 beats/min) o This is at rest (No physical activity is taking place) • Eighteen years old (boys)- 137 beats/min (can range between 101 to 172 beats/min) o This is while practicing an aerobic exercise Resting Heart Rate o The resting heart rate is simply the heart rate at rest. One good way to measure the resting heart rate is to count your pulse when you awake in the morning, before rising from bed. Alternatively, it could be measured when you first stand up in the morning (and the value will be slightly higher). To be most useful for establishing a trend, it should be measured the same way each day. o Ample evidence has shown that the resting heart rate decr... ... middle of paper ... ...ving the investigation: Limitation Improvement Amount of trials and people that participated in the lab. There were too many trials per person and this might have influenced on their recovery heart rate, and there were too little people per each group. I believe that I should have gotten more people in order to get a broader view of the athletes vs. non-athletes. I would also like to have made 1 less trial in order to make them have a bigger rest and so it would not have a much of influence on the results. Stopwatch in combination with the hand in order to check for pulse and heart rate. This was very complicated to do because at some point the heart rate was very fast and very difficult to count the number of heartbeats. By using a statoscope I believe it would have been easier to count the number of heartbeats in order to find out the recovery heart rate.
Another weakness in the experimental design was that the reliability of the experiment was very low. As each test subject was only tested against each amount of prior exercise once, the impact of random errors is likely very large, which can be seen by the spread of the data on the graph. Although, this was attempted to be rectified by averaging the results of all four test subjects, it does not improve reliability too
Submaximal and maximal exercise testing are two analytic methods that can be used to examine the cardiovascular, and cardiorespiratory fitness/health levels of the individual being examined. Submaximal testing is usually preferred over maximal mainly because the submaximal exam is more practical in a fitness/health environment. Both test require the individual being examined to perform controlled exercise on a(n) treadmill/ergometer until either steady state has consecutively been reached (submax), or the individual reaches their max (close to it). Being that both test are set to exceed time limits of more than 3 minutes we examine the use of the ATP-PC, Glycolytic, and Oxidative energy systems. Although a huge portion of the test involves the use of the oxidative energy system, we must remember that the three systems are co-occurrent.
Heart rate variability (HRV) reflects the variations in the intervals between heart beats (R waves) over time. The time between two consecutive R waves is termed the R-R interval; it is measured in milliseconds, and is controlled by the autonomic nervous system 1. HRV is a non-invasive method for interpreting autonomic nervous system modulation and provides information relating to each branch of the autonomic nervous system 2. Analysis of the beat to beat variability provides an insight into the relative contributions of the sympathetic and parasympathetic components of the autonomic nervous system’s control of the heart 34. In healthy individuals it is now widely agreed that under normal resting conditions, a high HRV is an indicator that the parasympathetic pathway is dominant over the sympathetic pathway. Consequentially, a large number of various disease states for example, cardiovascular disease have been linked to a low HRV reflecting increased sympathetic activity at rest 5. Studies have reported that regular practice of physical activity improves ...
... uptake during submaximal exercise but did increase heart rate and the rate-pressure product at rest and during both exercise and recovery’.
Within this set, the investigators randomized how many trials the participants would complete: 7, 10, or 13. Then, they were giving the chance to do 3 or 6 more trials and were ask to record their results.
Firstly we lay them on the back to get the resting heart rate and we

The Queens College/McArdle Step Test, the Rockport One Mile Walk Test, and the 1.5 Mile Run Test are three different field tests that were performed in this lab that were used to measure and predict an individual’s aerobic capacity. The measurement of aerobic capacity, or VO2 max, is a valid way to assess an individual’s cardiorespiratory fitness level. VO2 max refers to the maximal amount of oxygen an individual utilizes during intensive exercise. A higher VO2 max demonstrates a more efficient cardiorespiratory system as an individual with a higher VO2 max can sustain a higher intensity for a longer
What happens when an athlete that is in the best of physical health suffers a sudden cardiac death? The sudden death leaves the community, team, and family shocked and devastated and looking for answers.Whether they are throwing a pitch, shooting the game winning shot, running to the finish line, or making the tackle, an athlete in the United States suffers a sudden cardiac arrest every three days. ( Subasic 18 ) The deaths are rising in sudden cardiac deaths, but not all athletes die each time a cardiac arrest takes place. Each time an athlete suffers a sudden cardiac arrest they don’t all die, but the deaths are rising. Sports related cardiac deaths are very sudden and most scientists do not know why they occur, but researchers are conducting many studies to try to determine the exact cause. Therefore there have been many studies done trying
To determine if the intensity of exercise affects the heart rate of a 15-year-old boy. Apparatus - 2 stopwatches - 1 laptop (beep test) - 1 fire glass tape (min. 20 meters) - Chalk to mark 20 meters (start to finish). Method 1) Get beep test ready on laptop from - http://www.youtube.com/watch?v=e0U_yQITBks - 2) Bring five male subjects ready at the starting line to run the beep test. 3) Mark 20 meters on the ground outside on the AstroTurf using a long tape.
AIM: - the aim of this experiment is to find out what the effects of exercise are on the heart rate. And to record these results in various formats. VARIABLES: - * Type of exercise * Duration of exercise * Intensity of exercise * Stage of respiration
The two major things that will help an athlete while measuring the cardiovascular drift are progression and hydration levels. The heart rate of an athlete working hard during a workout should be no more than their maximum heart rate which is found by, if you’re a female take 226-age, if you’re a male take 220-age. If while doing a workout the maximum heart rate is exceeded by too much it may be necessary to take a break or slow down greatly. This may also help with traking the hydration of an athlete. If an athlete stays hydrated their core temperature will stay regulated which means they won’t sweat as much, which also means the heart won’t be under as much stress while transporting the oxygenated blood throughout the body to the
Creative new training methods, developed by coaches, athletes and sport scientists, are aimed to help improve the quality and quantity of athletic training ( Kellmann, 2010, p.1). However, these methods have encountered a consistent set of barriers including overtraining ( Kellmann, 2010, p.1). Due to these barriers, the need for physical and mental recovery in athletics brought an increasing attention in practice and in research ( Kellmann, 2010, p.1).
The materials used: one wristwatch (with second hand), two variably indifferent humans (one male, one female), and a standard staircase at CCC. The method was simple: two test subjects were exposed to two trials involving one minute of physical activity and x minutes needed for the recovery of the heart rate. Before the experiment began, each subject's resting heart rate was taken. This would become the controlled variable. Next, each subject ran up one set of stairs at CCC, one stair at a time, for one minute. After one minute of activity, the subjects stopped and began taking his or her heart rate.
This reflection of vital signs will go into discussion about the strengths and weaknesses of each vital sign and the importance of each of them. Vital signs should be assessed many different times such as on admission to a health care facility, before and after something substantial has happened to the patient such as surgery and so forth (ref inter). I learned to assess blood pressure (BP), pulse (P), temperature (T) and respiration (R) and I will reflect and discuss which aspects were more difficult and ways to improve on them. While pulse, respiration and temperature were fairly easy to become skilled at, it was blood pressure which was a bit more difficult to understand.
