Multiply this number of beats by four and record this number in the data table. Your partner should climb stairs or jog in place for one minute. Calculate the pulse rate after exercise by multiplying the number of heart beats in 15 seconds by four. Discuss why Byron must be able to get more oxygen to his muscles when he is climbing different sections of Mt. Everest. Design an experiment to determine the effects different kinds of exercise have on pulse rate.
Blood is forced through the arteries in waves called a pulse.
The blood transports oxygen and nutrients to all cells of the body. The oxygen is used by all cells to produce energy. Byron must have a constant supply of oxygen to all of his cells. When he is actually climbing, his heart must be able to pump more blood to his muscles. In this activity, you will take your own pulse at rest and after exercising.
