The heart rate will increase after exercising compares to
the heart rate at rest.

Material

·        
Timer

·        
Heart rate application (on the phone)

·        
Pen and paper to record the measure

·        
Procedure (to know what to do for the
investigation)

Method/Procedure

1. Record heart rate while sitting
2. Stand for 1 minute and record heart rate
3. Walk into the hallway in 1 minute, record heart rate
4. Take one-minute break.
5. Walk up and down stairs in 1 minute, record heart rate
6. Take two minutes breaks.
7. Run up and down stairs in 1 minute and record heart rate.
8. Record all data

Safety/hazards

·        
Ensuring that any individuals with identified
health issue does not take part

·        
Ensuring that all the activities should not
become complicated or challenging

·        
Ensuring that while doing exercise up and
down stairs, students should use handrail as needed

*heart rate measured in bpm

Observation

–         
Base on the data recorded that showing how
the heart rate changes during exercise. The heart rate can jump up to 160 BPM
while doing exercise such as walking, jogging or running. In compare to the
average heart rate while sitting or standing was 75 BMP and walking was 85 BPM.

–         
While doing exercise, the body felt hotter
than usual, breathing rate also change faster.

–         
Depend on individual health issue, the heart
rate could be lower or higher than the normal heart rate.

–         
Sometimes because the heart rate application
on the phone does not work very well, it took a while to record the heart rate.

Conclusion

The heart rates increase while exercise, it is fulfilling
with the hypothesis that exercise affects the increasing of heart rate.

Discussion

Heart rate is a number of the heart beats per minute.
Similar to heart rate is the pulse, it is normally found in neck or wrists
where the arteries throb rhythmically as blood is pushing through them. The
normal resting heart rate for adults ranges from 60 BPM to 100 BPM per minute
as stated by medicalnewstoday.com (MacGill, 2017). Sometimes, it’s varied from person to person.
Basically, the factors cause an increase in heart rate while doing exercise is
because the heart has to pump up more blood to make more energy to move, which
causing the pulse increases faster. In contrast, the decrease in heart rate
occurs after body takes four to five minutes for resting such as sitting or
standing. On the results that was recorded, it demonstrates exactly with the
factors cause increase or decrease of the heart rates. When people are sitting,
the heart rates range from 69 bpm to 93 bpm, it is a normal heart rate for
adults. As well as, when people were standing, the heart rates were increasing
a little bit from 85 bpm to 96 bpm. However, as the data shows that the heart
rates were normal before exercising but after doing exercise such as walking in
the hall way, jogging or running up and down stairs, the it was immediately
increasing. For example, as Zhen’s data showing that before she did the running
her heart rate was 93 bpm but after running, it was jumped up to 158 bpm. On the
other hand, people have low resting heart rate indicate a healthier heart
because if people exercise a lot that can lower the heart rate from 20 to 30
bpm according to outsideonline.com (Beresini, 2017). Exercising is time for heart to pump up blood
around the body so if people frequently exercising it would train the heart
pump more blood so that the heart would be in a good condition and do not need
to work as hard to maintain the steady beats. Overall, the more exercising the
more prevent the body from heart attack.

 

 

Evaluation

All the result based on the practical experiments. During
the investigation, it was a precious time to explore how the heart rates change
in different exercise. If there is anything that could improve the
investigation, it will be instead of putting the phone case on the phone,
better to take off the phone case before doing the heart rate record. That way,
the experimental process could be more efficiently and more reliable. Additionally,
although the procedure went through very well; every member in the group followed
all the instructions perfectly, however the procedure should be include the
recovering time.   The recovering time was very important for the
experiment. It should tell the students to double-check their heart rates before
doing the next exercise. Make sure the heart rates return to normal, and then
record the results for the before exercising and after exercising.
