Five college females (age – 19.6yr. ± 1.5; ht – 167.5cm ± 5.65; wt -162.29 ± 5.64) all members of the St. Thomas woman’s track team and engage in sprint workouts two to three times a week volunteered to be in this study. Heart rate was determined using a Polar Heart Rate monitor (model E600) which was set to measure heart rate at five second intervals. The first time heart rates were taken was during a 200 meter track workout. The workout consisted of running six 200 hundreds at 85% (roughly 30-32 seconds) with two minutes rest in between each 200. Heart rate monitors started recording at the beginning of the actual workout (after warm-up) and was stopped as soon as the subjects crossed the finish line of their last 200. The second time heart rates were recorded was during the exercise bike workout (Lifetime Fitness Exercise Bike). This workout consisted of each subject doing a bike version of the same workout; which was maintaining an RPM on the bike of 130-135 for 30 seconds (to simulate the 200’s) then resting for 40 seconds (lowering the RPM to 50-60).
Significant differences between the heart rates on the bike and track where calculated using a paired t-test. Data is being analyzed.
