Biology Practical Report on Pulse Rate

1818 Words8 Pages

Pulse rate is the number of times in a minute an artery pulsates or the rhythmic expansion and contraction, which indicates that a heartbeat has occurred. There are many factors which affect the pulse rate which includes: gender, age, body temperature, pain, emotion, exercise, blood pressure, consumption of stimulants, dehydration, body mass index (weight), fitness level, lifestyle and many more. In my investigation, I would be examining the affect of gender in the change in the pulse rates, while keeping the other factors constant.

Background Information:

The pulse rate is a measurement of the heart rate, or the number of times the heart beats per minute. As the heart pushes blood through the arteries, the arteries expand and

The rest of the factors will be assumed to be constant as in practical, it is not possible to identify the pain, or emotion in the person whose pulse rates is being acquired.


* Stop watch/ clock * Notebook/Paper * Pen/Pencil


1. Initially make perfectly sure that the person whose pulse rate is being measured is perfectly fit or not 2. Ask the person to sit down silently for 5 minutes or so * Take his/her hand and using the first and second fingertips, press firmly but gently on the arteries until you feel a pulse. 3. When you feel it, keep one of you fingers firm on that position and with the other hand start the stopwatch * Start the stopwatch, and count the pulse beats for 60 seconds (or for 15 seconds and then multiply by four to calculate beats per minute). * Ask him/her to stand up and again take the account of the pulse beat as before (see step 3-6) 4. Then ask the person to do hard jogging for about 1-2 minutes 5. Take the pulse rate again (see step 3-6) 6. Repeat the steps for 10 males and 10 females and tabulate the readings in the data table


Safety Precautions:

* Make sure that the person whose pulse rate is being tabulated is healthy and exercises regularly or not * Make sure both the genders lie in the same age group *
