Introduction

XXXIII Copernicus High School Warsaw April 20, 2009 Sabina Narloch THE INFLUENCE OF DEFINED FACTOR ON THE PULSE RATE RESEARCH QUESTION Does heart rate differ significantly in accordance to genetics, gender, age, surrounding us environment, and lifestyle? Does heart rate may also be influenced by factors with which we do not face in everyday life as overwhelming, strong emotions? VARIABLES Possible effect on heart rate 1. Type of exercising More body's parts are involved in exercising, the higher heart rate1 2. Resting After exercising lowers heart rate 3. Wearing different textile materials during exercise Rises physiological parameters such as body temperature causing increase in heart rate2 4. Emotional states Emotional states are connected with hormones production which may rise heart rate3 5. Liquids as alcohol, coffee, tea These liquids cause increase in heart rate4 6. Kind of breathing, e.g. deep, shallow Faster breathing, higher heart rate5 INDEPENDENT 7. Body's position (lying/sitting/standing) Harder supply of blood (heart has to pump more vigorously), higher heart rate6 VARIABLES 8. Hydration Failing to stay hydrated can result in an increase in heart rate7 9. ...read more.

Size of the heart Size of the heart may be dependent on genetics precondition/lifestyle, effect are adequate17 MATERIALS AND EQUIPMENT * Stopwatch (�0.01 s) * Barometer * Hygrometer (� g/m3) * Thermometer (range: 0 oC-100 oC, � 0.5 oC) * A large area to carry out the experiment * Stethoscope (if heart rate would not be measure placing fingers) * Stairs * People of both sexes, in different age , with and without smoking status, with and without alcohol addiction, with normal and overactive thyroid gland, with good/poor physical condition, with low/normal/high blood pressure, with diversity in height, and also with diverse Body Mass Index * Liquids: alcohol, coffee, tea, water * 20 mugs with 1 liter of capacity * Graduated flask (needed to measuring out liquids' volumes; �0.01 l) * Chair * Sofa PROCEDURE 1. All equipment mentioned in Materials was prepared. 2. Six groups (each group consisted of seven persons) of people were created considering sex, difference in age , smoking status, alcohol addiction, normal/overactive thyroid gland, good/poor physical condition, low/normal/high blood pressure, person's height and also diversity in Body Mass Index. ...read more.

Conclusion

before and after experiment. 13. Ninth group of people (that consisted of ten persons) was created considering lack of sleep (five people) and emotional states (five people). 14. Heart rate was counted (see point "3") before and after long-lasting lack of sleep/felt strong emotions. 15. Tenth, the last group that consisted of fifteen people was created. 16. Group's members were divided into three smaller groups (five people in each) considering influence of body position (lying/sitting/standing). 17. Heart rate was counted (see point "3") after 30 minutes in such position. 18. All experiments were carried in identical conditions, controlled variables were maintained (time was measured by stopwatch, � 0.01s; atmospheric pressure was measured by barometer: � ; heat by thermometer, � 0.5 oC, humidity by hygrometer: � g/m3). 1 "How Exercise Affects Heart Rate" ,Manuel Gotti (a pseudonym) 2 "The effects of textile materials on body temperature and heart rate of a semi professional footballer", George Churchill Research Proposal SSP200 3 http://www.heartmath.org 4 http://www.diabetesmellitus-information.com 5 http://www.hypnosishealthcare.com 6 http://www.intime.uni.edu/video/024iams/3rus/default.htm 7http://www.polar.fi/en/training_with_polar/training_articles/improve_performance/general/factors_that_influence_heart_rate_during_outdoor_training 8 http://www.usatoday.com/news/health/2007-09-16-sleep-deprivation_N.htm; Tali Yahalom 9 http://www.nature.com 10 http://www.ncbi.nlm.nih.gov/pubmed/7963118 11 http://www.scribd.com/doc/13419890/Effect-of-Supervised-Integrated-Exercise-on-Heart-Rate 12 "Biological Science 1&2" third edition; D.
