Exercise causes many elements of homeostasis to do its stuff to maintain inside equilibrium. How exercise influences some of these elements can be determined by simply measuring and observing certain conditions with the human body.

• perspiration level

• external body temperature

• breathing charge

• heartrate

Prelab Notes

1 ) Working in groups of 3 or 4, pick a student that is able to jump rope well increase in able to maintain jumping intended for 8 mins. The group member jumping will stop merely long enough to get the needed measurements and observations being collected. 2 .

Brush your thermometer with alcohol and return this and all various other lab supplies to the designated area. six. Make a different graph for every of the pursuing:

• Exterior Body Temperature at Various Intervals of Work out • Deep breathing Rate for Various Time periods of Physical exercise • Heart Rate at Different Intervals of Exercise

several. Answer the questions inside the conclusion section to describe and explain the results with the lab.
