Abstract
Exercise has traditionally been used as a forum to disrupt a body’s anatomical systems in order to understand how they behave under stress. I am investigating the differences in heart rate and lactic threshold in female distance athletes and sedentary females. Lactate threshold is one of the aspects that constitutes for anaerobic threshold. Anaerobic threshold characterizes a point when metabolic acidosis, along with the associated changes in gas exchange in the lungs, occurs during exercise. In this experiment, subjects were asked to bike on a stationary bike for 18 minutes at 60rpm. The watts began at 50 and increased by 50 watts every 3 minutes. Each 3 minute segment comprised one “stage” of the test. The participant’s finger was pricked for lactic acid measurements before the subject got on the bike, during stages 2, 3, 4, and 6, and after the subject’s heart rate was within 10% of their resting heart rate, or after 15 minutes had passed after the conclusion of the bike test. Heart rate was constantly monitored using a heart rate strap and was recorded at the same time as the lactic acid measurements. Hemoglobin and hematocrit was also measured prior and at the conclusion of the established bike protocol to examine the effects of dehydration. This topic is important to find a potential association between heart rate and lactic acidosis and its impact on performance in athletes. This will allow for specific training in athletes to help improve their aerobic threshold for training by decreasing their lactic acidosis.
