Title

COMPARISON OF ENERGY EXPENDITURE AND CYCLING EFFICIENCY IN PROFESSIONAL AND AMATEUR CYCLISTS

Pages

  27-46

Abstract

 Cycling efficiency is a key determinant of endurance cycling performance. Despite this, previous studies that have compared cycling efficiency during cycling between professional and amateur CYCLISTs have reported inconsistent results. Hence, The purpose of this study was to compare the ENERGY EXPENDITURE, cycling efficiency and economy between professional and amateur CYCLISTs. Forty-two professional CYCLISTs (27.3±4.2 yr) and 31 amateur CYCLISTs (23.7±3.6yr) performed an incremental cardio respiratory exercise test (ramp) on a bicycle ergometer until volitional exhaustion. ENERGY EXPENDITURE was calculated from the measures V Co2 and Vo2 obtained from the gas analyzer using the formula of the Brouwer. Cycling efficiency and economy were calculated as the power output divided by the rate of enerdy expenditure and oxygen consumption during working loads of 200,300 Watt. The results showed that there was no significant difference in cycling efficiency (amateur; %22.58±1.76 vs. professional; %23.27±2.45) and economy (amateur; 4.68±0.37 kj/l vs. professional; 4.79±0.51 kj/l) between two groups at working load of 200w, but at working load of 300w were significantly higher in professional CYCLISTs than amateur CYCLISTs (efficiency; %23.78±1.72 vs. %22.58±1.76; p=0.011, economy; 5.03±0.37 kj/l vs. 4.75±0.27 kj/l; p=0.011). ENERGY EXPENDITURE was significantly lower in professional CYCLISTs at working load of 300w (1263±98 vs. 1333±71 j/s; p=0.018). There was no significant difference in cycling efficiency and economy between working loads of 200w and 300w in total CYCLISTs. The findings of present study suggested that professional CYCLISTs have more cycling efficiency compared with amateur CYCLISTs, that may explain the major functional differences in higher intensities between them.
