The Scientific Methods – Lab Report Example

Report of the experiment: Exercise and Cardiovascular fitness Introduction The experiment was designed based on the hypothesis that differences in cardiovascular fitness exists in men and women. Hence, in order to determine which gender had a better fitness rate, both male and female participants were made to perform a simple exercise and subsequently the pulse and heart rate were determined prior, during and after the completion of the exercise. The recovery time taken for the heart and pulse rate to return to normalcy was also determined by checking the aforementioned variables after a period of time. The results showed that the women participants had a stronger pulse and heart rate and thus possessed better cardiovascular fitness compared to men.
Study purpose
The purpose of the study was to investigate the differences in cardiovascular fitness among men and women and subsequently ascertain which gender exhibited better fitness levels.
Hypothesis
The experiment is based on the hypothesis that differences in cardiovascular fitness exist in men and women and that female’s possessed better fitness levels compared to males.
Experiment
The experiment was conducted in groups wherein each group had one male and one female participant. At the onset the pulse and heart rate of each participant was checked and noted. They were then made to perfume step up exercises and at the same time their pulse and heart rates were monitored and a watch was used to track the time. The study variables were then measured immediately after completion of the exercise and again after a period of rest in order to determine the recovery time taken by the individual to restore the heart and pulse rate to normalcy after performing an exercise.
Results
The experiment revealed that the heart and pulse rate of females was much stronger compared to males and hence they exhibited better cardiovascular fitness compared to their male counterparts. Additionally the recovery time taken by the female participants was quicker compared to males. Graph 1 shows a comparison of the pulse rate measured in beats per minute among men and women both before and after completion of the exercise. The pulse rate is slightly higher in both the sexes after exercise with the females having an increased rate as compared to men. A similar effect was found during the measurement of respiratory rate in terms of breath where the females had a higher rate than men after exercise. At the end of the exercise females regained their pulse rate quickly than males while the recovery of the respiration rate was the same in both men and women.
Discussions and Conclusion
The experiment completely supported the hypothesis that females have better cardiovascular fitness compared to males and that the time taken for recovery after an exercise is comparatively quicker in the female participants. While the present study included a simple exercise to determine the cardiovascular fitness in both genders, more complex and heavy exercises could be used and the fitness rates determined subsequently. A more reliable method could be used to determine the respiration rate in future experiments.
