Title Differentiation of Heart Rate and Blood Pressure of Female Collegiate Athletes versus Female Collegiate Non-Athletes during exercise Alicia Burt Undergraduate Student Biology-Health Sciences Tennessee Tech University PO Box Cookeville, TN 38505

Introduction zShow how following a strict exercise regimen influences heart rate and blood pressure when compared with not following a strict exercise regimen zHow heart rate and blood pressure of female collegiate athletes is different than female collegiate non-athletes before and after exercise

Introduction zNormal blood pressure is 120/80mmHg (Marieb 2004) zNormal heart rate is 60 beats per minute (Marieb 2004) zEffects of aerobic exercise on blood pressure showed small reductions of 2% in systolic and 1% in diastolic pressure (Kelley 1999) zIncreased ventricular wall thickness of marathon runners resulted in lower heart rates and lower systolic pressure when compared with normal subjects (Percy 1990) zMen and women generally exhibited similar patterns in postexercise blood pressure over an extended recovery period (Fisher 2001 )

Objective/hypothesis statement zObjective is to show how heart rate and blood pressure differ for athletes and non-athletes before and after exercise zHypothesis states that the athletes will have a lower heart rate and blood pressure when compared to non- athletes before and after exercise zNull hypothesis states that the heart rate and blood pressure will be the same for athletes and non-athletes

Methods and materials zFollow method Percy used in testing for left ventricular wall thickness zI will have two different groups of subjects (Percy 1990) zGroup A-athletes / Group B-non-athletes zTest for blood pressure using the blood pressure cuff over the brachial artery (Percy 1990) zFirst heart sound you hear is the systolic pressure zLast heart sound you hear is the diastolic pressure zWill test for heart rate immediately (bpm) and blood pressure 2 minutes before and after exercise of 40 jumping jacks

Results and Discussion zBP for athletes and non- athletes are very similar before exercise

Results and discussion zBP for athletes and non-athletes are very similar after exercise

Results and discussion zHR for athletes is lower than non-athletes before exercise

Results and discussion zHR for athletes is lower than non-athletes after exercise

Conclusion zBlood pressure for the athletes and non-athletes before and after exercise were very similar zDid not have much differentiation between the two groups zThis conclusion went against my hypothesis

Conclusion zHeart rate for the athletes was lower than the non-athletes before exercise zHeart rate for the athletes was lower than the non-athletes after exercise zThis conclusion supported my hypothesis zFollowing a strict exercise regimen has little effect on your blood pressure but can lower your heart rate
