Abstract
The effect of cycling in two different body positions on work output and on several cardiorespiratory parameters was studied in nine cyclists. Oxygen uptake (VO2), heart rate (fH), pulmonary ventilation (VE), and work output (W)were measured for the top bar (TB) and drop bar (DB) seated cycling positions.Significantly higher VO2, W (P<0.05), and VE (P<0.01) were found for the DB posture. The VO2max and VEmax were 0.24 and 10.48 liters/min higher for the DBposition. No difference (P>0.05) was found in fH between the TB vs DB cycling positions. The maximal work output in the TB position was 86 of that for the DB position, while VO2 in the TB posture was at maximal effort 7 lower than for the DB position. The postural difference for VO2 PWC170 measured 10 greater in the DB position. The major findings were an increased work output and related variables when cycling in the drop bar position as compared to thetop bar position. It was concluded that the body posture assumed during cycling is crucial for optimum performance. Verf.-Referat
