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,
