INTRODUCTION
The report is about a study conducted on students of university to find out effect on
exertion on heart rate. It will answer question that whether there is relationship between effect
of heart rate or not. (Edelstein and Wang, 2016)
Hypothesis -
null – there is no significant relationship between effect of exertion on heart rate
alternate hypothesis- there is significant relationship between effect of exertion on heart rate
Methods
Collection of data - it is necessary to gather relevant and precise data so that hypothesis can
be tested. If data is not collected properly then it can led to ineffective outcomes. This highly
impact on hypothesis testing (Hassamal and Danovitch, 2017). Thus, in order to test these
hypothesis a sample of 36 students has been taken. Their before and after heart rate will be
recorded to find out effect of exertion on heart rate. Furthermore, primary data will be
gathered. So, in order to record heart rate medical equipment will be used. The study is ethical
as there is no forceful entry of students and also no harm will be caused to them. Besides that,
data gathered will not be shared with any third party and is kept secured and protected.
In this data of students of Queens building was gathered before and after exertion.

Interpretation- From table it is analysed that there are significant value obtained in P = .000
which is less than P =0.05 thus alternative hypothesis is accepted. It means that there is effect
of exertion on heart rate. There is difference in before and after heart rate of students.

Interpretation- By interpreting table it is found that P value is .480 that is more than P =0.05.
thus, alternative hypothesis is accepted. It means there is effect of exertion on heart rate. It
highly impact on heart rate as student can feel difference on it before and after exertion. (Ye
and Waddle, 2017)
Discussion
Therefore, from study it is discussed that before doing any physical exercise student
heart rate is normal. However, when they do exercise after that heart rate increases. This is
because here energy is consumed. They have to put on effort to do exercise. So, more energy
and effort are needed. Due to it, heart rate increases as blood supply increases within body.
Therefore, there in effect of exertion on heart rate.

Conclusion
It is summarised that exertion is doing of exercise. Thus, it directly impact on heart
rate as energy is consumed and blood circulation increases. Hence, alternative hypothesis is
accepted as there is effect on exertion on heart rate.
