In the present study, a tandem-bicycle ergometer was developed, because it is believed that such an ergometer can be used to eliminate differences in signaling between single- and tandem-exercise in cardiorespiratory responses, and is able to quantify interdependence in one load. It is necessary to verify whether cardiorespiratory responses to submaximal exercise are the same between single and tandem-bicycle ergometers. Accordingly, we compared cardiorespiratory variables during exercise in three conditions: 1) with a general bicycle single saddle using a general bicycle ergometer, 2) with a tandem bicycle front saddle using a tandem ergometer, and 3) with a tandem bicycle rear saddle using a tandem ergometer. Eleven healthy males participated in this study. The subjects exercised for 15 min at three intensities (1.5, 2.0 and 2.5 kp) in each condition. The pedaling rate was constantly kept at 60 rpm. Heart rate (HR), oxygen uptake (VO<sub>2</sub>), and the rating of perceived exertion (RPE) were measured during the last minute of each intensity. There were no significant differences in the variables HR, VO<sub>2</sub>, and RPE at each load among the three conditions. The ranges of coefficient of variation (CV) values were 3.0 - 4.8%: HR and 4.2 - 5.1%: VO<sub>2</sub>. It was reported that between-day CV for HR and VO<sub>2</sub> during treadmill running was 1.0 - 10.7% and 1.9 - 11.6%. Given these CV values of present and previous studies, it can be seen that physiological response is stable during developed tandem-bicycle ergometer exercise. These results suggest that cardiorespiratory responses to exercise are at comparable levels between a normal bicycle ergometer and the newly developed tandem-bicycle ergometer.
