The purpose of this study was to assess the energy demands of a 2,000 meter race simulation (RS) for national level oarswomen. A progressive intensity test (PIT) was also performed on the rowing ergometer (RE) to evaluate the RS further. Six national level oarswomen (mean values: age, 24.5 yr; height, 179 cm; weight, 75 kg) participated in this investigation. A 6½ minute tape‐recorded water race was used to execute a 2,000 meter RS on a RE. The tape recording was an actual race tape that was modified to last exactly 6½ minutes. Results on the RS indicated a mean maximal oxygen consumption rate (VO2max of 3.851‐min‐1, a mean net VO2 of 24.481, and a mean recovery VO2 of 4.921. This represented the aerobic cost of the event at approximately 80%, or four fifths, of the total energy cost, whereas the anaerobic contribution was approximately 20%, or one fifth, of the total energy cost. During the RS, VO2max (3.85 1‐min‐1) plateaued in the first 2 minutes. The mean maximal ventilation per minute (VE) (body temp... |
