Abstract

Background: This machine was created under the expectation that it gave a better cardio workout than a regular cycle ergometer. Methods: The purpose of this study was to compare the metabolic effects during a similar bout of exercise on the Fish and Kangaroo Machine (FKM) and a cycle ergometer. Recreationally active individuals (men, women; N=13) completed two workouts, one on the FKM and the other on the cycle ergometer. The exercise protocol included intervals alternating between exercise (3-min) and rest (3-min) for a total duration of 23-min. After the 1^st exercise bout (on the FKM) the heart rate response on the FKM was used to establish the cycle resistance for the 2^nd exercise bout. Heart rate, cardiac output, stroke volume were measured using a wireless telemetry technique (Physioflow Enduro). Oxygen consumption (VO₂) was measured via breath-by-breath automated analysis of expired respiratory gas (MGC Diagnostics Ultima). Capillary (fingertip) blood lactate was measured using a handheld meter (Lactate Plus Nova Biomedical). With the exception at the beginning, at the beginning of each rest interval and at the very end of the last rest interval. Results: During rest intervals heart rate, stroke volume, and cardiac output returned to resting levels when exercising on the bike; however, when exercising on the FKM stroke volume remained elevated. VO₂ was lower on the FKM compared to the bike. With the exception of the last exercise interval blood lactate values were similar between the two exercise devices. Conclusions: Both modes of exercise demonstrated similar physiological responses; however, the FKM appeared to have a slightly greater anaerobic component. Given the nature of the way the exercise intervals were designed; it is plausible that the FKM may be best used as an aerobic training device. More research is needed to determine how to best use FKM exercise as a part of a comprehensive training program.
