The ecological validity of laboratory cycling: Does body size explain the difference between laboratory- and field-based cycling performance?

摘要: Abstract Previous researchers have identified significant differences between laboratory and road cycling performances. To establish the ecological validity of time-trial performances, causes such should be understood. Hence, purpose present study was to quantify laboratory- road-based what extent body size [mass (m) height (h)] may help explain differences. Twenty-three male competitive, but non-elite, cyclists completed two 25 mile time-trials, one in using an air-braked ergometer (Kingcycle) other outdoors on a local course over relatively flat terrain. Although speed reasonably strong predictor (R 2=69.3%), 4% difference (P < 0.001) (laboratory vs. speed: 40.4 ± 3.02 38.7 3.55 km · h−1; mean s). When linear regression used predict these (Diff) i...
