Elliptical cross trainer has become popular for cardio respiratory fitness training. Since new models of elliptical trainers are manufactured for better design and more effective in workout, the present study attempted to compare the physiological variables of the latest model of elliptical trainer, Precor AMT 100i, with the previous model, Precor EFX 576i. A total of 30 female university students participated in the 12-minute incremental elliptical test. Heart rate data and energy expenditure were recorded. Results showed that the latest elliptical model required higher heart rate and energy output, comparatively. However, it appeared that overestimation in energy expenditure was found from the machine-shown data, as compared to the actual metabolic measurement. All data between 60%, 80% heart rate reserve and the equivalent perceived exertion of subjects was found to be no correlation.
