These tables show the heart rate in beats per minutes before, during, after and percent change. Percent change is how much the heart rate changes from the before to during measure for each subject. Subjects two and three were unable to complete the third trial. Discussion:Subject #1:Subject #1 is a female who participates in recreational soccer and high school band. In Trial #1, the subject’s heart rate became slower during the water submersion period from 61 bpm before to 58 bpm during. This supports the hypothesis that heart rate will decrease while experiencing the Dive Response. Trials #2 and #3 also supported the hypothesis where the heart rate in bpm decreased. The percent change in Trial #2 is 20% while in Trial #1 it is only 4.9%, this is due to the drastic difference in before heart rate from 61 bpm in Trial #1 to 70 bpm in Trial #2. This shows bradycardia due to the Dive Response caused by the anoxia while the subject’s face was submerged. Tachycardia occurred once the subject emerged from the water in Trial #1

since the heart rate rose to 61 bpm. Due to the apnea she experienced, bradycardia occurred during the submersion period.Subject #2:Subject #2 is an active male that exercises 3-4 times a week and is also beautiful. In Trial #1, the subject’s heart rate was at 80 bpm before submersion and during submersion it slowed to 50 bpm. The anoxic conditions caused dramatic bradycardia within Subject #2. This supports the hypothesis that heart rate will decrease while experiencing the Dive Response. From Trial #1 to Trial #2 the percent change changes drastically from 37.5% to 13.5% possibly due to adaptation in Trial #2. Apnea caused bradycardia and tachycardia occurred once Subject #2 submerged out of the water and heart rate was measured. Trial #3 was not performed.
