At the start of the paper (Lancaster et al., 2004) the abstract is written well by stating their hypothesis, whether heat shock protein 72 (Hsp72) can be released during times of physical stress. This section also contains data collected from the results to give the reader a clear insight in to what to expect to find. It is my opinion, the abstract is a positive due to it enticing you in and explaining what the study will be about. Following on from the abstract the introduction goes in to extensive detail in to studies previously undertaken around Hsp72, these go in to great detail of what the other articles have found. Citing papers that are up to date for their time, around the late 20th century and the start of the 21st century as …show more content…
It is my belief that the authors(Lancaster et al., 2004) were justified in using this citation. To run experiments with human subject’s ethical approval is needed and for this they received their approval from the Ethical Committee of Copenhagen and Frederiksberg in accordance with Declaration of Helsinki. Which has appeared in other articles related to research based on Hsp72 (Peart et al., 2011). For this experimental procedure factors needed to be controlled to ensure they had no effect on results for example, uptake of nutrients and environmental conditions. These were controlled by having a period of fasting and specific carbohydrate drinks to drink during exercise and the room temperature kept at 21±1°c. Although these are good points for the method, it also comes into criticism as well. Firstly the use of a catheter in the antecubital vein with no mention on how stressful this could be on the subjects. An improvement on this method would be to take blood samples without a catheter either at the start and end of the exercise session or at intervals during the session (Magalhães et al., 2010). Secondary the use of only 6 highly trained men with a mean age range of 26±2 years as a sample size, this doesn’t fairly represent the population and from my research I can find no large size study for this topic with the greatest sample size being 16 men (Périard, Ruell, Caillaud, & Thompson,
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.
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).
In this assignment I will be introducing a formal report that is based on an investigation into how the body responds to exercise and which analyses the results from the investigation. The investigation involves myself and other pupils in my class. I will be doing the Harvard step test. the other pupils in my class will be monitoring my heart rate, breathing rate and temperature before and after the test.
The major aim of the commission, which made the Belmont report was to ensure that ethical principles are followed during a research involving human beings as the subjects. The commission was tasked with considering the instinct between the biomedical and behavioral research and the normal routine that have been acceptable in medicine. It was also tasked with assessing the various risks that arise in determining the use of human during research exercise. The commission also was to establish the various necessary consents during the research settings.
P6- follows guidelines to interpret collected data for heart rate, breathing rate and temperature before and after a standard period of exercise
Does the experimental testing of Creatine answer all questions asked such as will Creatine increase mass and strength? Was a
In this lab, the focus was to study muscular fitness. In muscular fitness, there are two main components of measurements that are being taken, which are muscular strength and muscular endurance. Muscular strength is an individual’s ability to exert their maximum force. To test muscular strength, there are multiple tests such as 1 RM , Static Handgrip Strength, and Back Strength Dynamometer test. Muscular endurance is an individual’s ability to sustain prolonged muscular contractions. Tests that reveal results about an individual’s muscular endurance would be tests such as YMCA Submaximal Bench Press, Push-Up, and Plank test. It is important to remember that there is no single test for endurance and strength that will tell an
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.
The criteria for articles chosen was that each piece of research needed to involved the intake of CR, and being physically or athletically tested pre and post ingestion of CR with no other supplementation, steroid, or health related drugs involved. All research articles were double blind with placebo groups to prevent the effects of bias and placebo effects. All research was done within the previous 16 years and a balance of gender was aimed for in order to be unbiased but resources were mainly male orientated. Time period was not contained as a variety of short and long term supplementation is good to compare the different effects of sports performance over different durations of supplementation. Age of subjects in experiment weren’t
Our experiment was performed in the Science and Technology build on the USCB Bluffton Campus on October 6th from 4:30 to 5:30 p.m. In order to construct the study for this experiment, we divided the actual experiment work in order to be able to complete the study for all sixteen (16) subjects within the given time period available to accommodate the test subjects. The experiments was conducted in the hallway, during the process we tested three participants at a time. We constructed an informational form regarding gender, age, weight amount of exercise per week. The supplies needed were approximately 25 test participants for the class, informational form, a blood pressure reader, timer, 15 jumping jacks, three chairs, paper and pencil to record
All subjects must be in good health on the day of the experiment and should be excluded if they have suffered from cardiovascular, renal, metabolic or respiratory illnesses,
a. The study was conducted in accordance with the ‘Recommendations Guiding Physicians in Biomedical Research Involving Human Subjects’ in the 1989 Declaration of Helsinki.
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.
The only limitation was not asking the people who participated in the experiment whether they lead a healthy lifestyle or not for example if they do a lot of sport. Next time I would have also done the experiment on more people to get more of an accurate reading. Evaluation: The Results of my experiment showed that the taller a person is, the larger flow of air or lung capacity they have. This is proven by the data I collected.
The subjects refrained from caffeine, standardized diet, and standardized training for 48 hrs before the trials. For 24 hours before the trials, each subject was given a prepackaged standard diet. Exercise and food diaries were kept and checked for compliance.
