Introduction
Introduction

• This is a Year 9 Science Project carried out by
  Joshua Lam, Fabien Schaeffer and Janam Shah.
• Our group has chosen to study on how human heart
  pulse rate is affected by different physical
  activities
• This presentation describes the study method
  used, information collected and analysis of the
  results.

3
Study Method

• Firstly, the group researched from the internet
  the pulse rates at different age groups under
  normal and sport conditions. These data are used
  as a reference.
• Secondly, the pulse rates of three participants
  were measured under normal condition.
• The participants then carried out a designated
  physical activity. Their pulse rates were
  measured again during and immediately after the
  activity. The experiment was repeated on the
  next day with another activity.
• The results were then studied and compared with
  our Hypothesis and Control.

4
Hypothesis

• The more vigorous the sport that people carry out
  , the higher the heart pulse rate will reach.
• This is because the human body needs to adjust
  for additional demand for oxygen and energy
  during the activities.

5
Variables

• In this experiment, the amount of time spent on
  each activity was varied as well as changing the
  type of activity e.g. football, running etc.
• Collectively, this effectively vary the
  intensiveness of activities each of us carries
  out.
• However, our group did not vary the age group as
  our group only wanted to study the results of the
  age group 13-14.

6
Field Measurements

• Three participants were requested to carry out a
  series of sport activities throughout a week
• Name Age
• Janam 14
• Joshua 13
• Fabien 13
• The activities include
• Football
• Shuttle run
• Sit-ups
• Push-ups
• Their pulse rates were measured before and
  immediately after each activity
• The results were also compared with data from
  similar studies obtained from the internet.

7
Equipment

• The following equipment were used to carry out
  the experiment
• Stop watches
• Video cameras
• Measuring tapes
• Pulse monitor
• And a football !!

8
Control

• The average heart rates of the following age
  brackets during exercise are used as the
  reference

Analysis

• We then compared our results with our control and
  our hypothesis.
• Generally, the more vigorous and the more
  demanding the activity is, your heart pulse rate
  tends to go higher.
• From our results, we can see that football is the
  most demanding sport that we did, which is
  followed by running, push ups and then sit ups.
• As we calculated, football is about 15 more
  demanding than the sit ups.
• We also noticed that our heart rate are very
  similar to the ones posted on the health related
  website.

15
Conclusion

• The studies that our group show that the heart
  beat rate increases when the exercise becomes
  more vigorous and longer. So
• Generally, the more vigorous and the more
  demanding the activity is, the heart rate
  increases.
• The fitter you are, the less increase you have.
  This is because your body doesnt require as much
  oxygen as less fit people.
• Your heart has a highest level of pulse rate that
  it can get to. This varies with age, as well as
  your fitness level.

• Findings
• Human body adjusts its heart pulse rate
  according to different activity levels
• This is necessary as the body needs more oxygen
  and different amount of energy for different
  activities
