Abstract

ABSTRACT

Purpose: To compare the physiological differences between highly trained resistance and aerobic athletes (who perform five or more hours per week of resistance or aerobic exercise).

Methods: Participants had resting heart rate, blood pressure and lactate taken before entering the BOD POD to get body fat percentage. Then a five minute warm up on a cycle ergometer before doing the VO2 max treadmill test following the Bruce Protocol. At the completion of the VO2 max treadmill test, participants had heart rate recorded from the heart rate monitor, blood pressure and lactate were taken immediately after the max test. The sample size was n=9 for AG and the sample size for RG was n=8.

Results/Conclusion: All variables were compared among AG (aerobic group), RG (resistance group). The AG VO2 max average was 2.6ml/kg/min higher than the RG, with their max VO2 max result 6.4ml/kg/min higher than the max RG VO2 result. The AG body fat percent average was 4.3% higher than RG and percentile averages were 9.7 below RG averages. The AG resting systolic and diastolic blood pressure was about the same as the RG, however they had a higher final systolic blood pressure by 5mmHg on average and a lower final diastolic blood pressure by 11 mmHg on average. The AG had 10bpm lower resting and 5bpm lower final heart rate averages as well as lower minimum and maximums for both. The AG had a resting lactate level of double the RG (4.8mmol compared to 2.2mmol) and they both had the same final lactate level averages. However, the AG had a higher minimum and maximum resting and final lactate level. In conclusion, VO2 max and lactate levels increase with aerobic training while heart rate pre- and post-exercise decreases.
