Abstract
Lactate threshold device (LTD) assists subjects in improving athletic performance and maximizing calorie burn. LTD digitizes the electrocardiogram (ECG) obtained from a chest belt with a first signal analyzer, and telemeters the ECG to a second signal analyzer. LTD uses a novel algorithm to convert the telemetered ECG from the time to frequency domain, utilizing a digital signal processing method called fast fourier transform based spectral analysis. LTD determines whether lactate threshold (LT) has been reached, and furthermore calculates heart rate, heart rate variability, and heart rate and power zones. LTD displays the determined variables on a local or remote display. Subject using LTD obtains feedback during a real-time exercise regimen in the field that has aerobic (below LT) and anaerobic (above LT) zones. By utilizing an exercise program with aerobic and anaerobic zones, both sprint and endurance fitness levels are improved, and weight loss potential is maximized.
