dc.description.abstractOBJECTIVE: To determine the differences in physiological performance at constant submaximal load and aerobic power levels of electromagnetically and mechanically braked cycle ergometers. METHOD: Nineteen trained male athletes who specialize in cycling and triathlons participate in this study (age, 20.21 +/- 3.50 years; body mass, 73.36 +/- 13.19 kg; height, 178.73 +/- 8.54 cm). A randomized cross-over study design was used to compare a mechanically braked Monark cycle ergometer (MCE) and an electromagnetically braked Lode Excalibur cycle ergometer (ECE). After the VO2max test, total physical work capacity and work efficiency (GE) were analysed during 60% of VO2max constant loading submaximal tests with MCE and ECE. A paired sample t-test was used to compare VO2max and constant loading submaximal test data of the ergometers. RESULTS: Applying the ECE system resulted in a significantly higher VO2max value (9.3%; p = 0.004), similar respiratory exchange ratio value (1.8% lower; p = 0.290), similar power output at exhaustion point (1% higher; p = 0.620), significantly higher total energy expenditure at exhaustion point and mean cadence (Cad(mean)) value (12%; p = 0.025, 9.6%; p = 0.000) respectively. In the constant loading submaximal tests, however, significant differences were found in mean power output (p = 0.013), Cadmean (p = 0.000), and GE (p = 0.000) values. CONCLUSION: Since the ECE system was associated with a higher VO2max and allowed test performance at the expected VO2 consumption at constant submaximal loads, we recommend using the ECE for determination of aerobic power and total physical workloads.en_US
