Abstract
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 temperature, pressure, saturation) RS value was 122.4 1‐min‐1. VE plateaued after 2 minutes and remained close to 90% of PIT mean maximal VE for the final 4½ minutes. The mean maximal excess carbon dioxide for the RS was 19.81 ml‐kg‐1‐min‐1. The average maximal heart rate, recorded during the RS, was 193 bpm. The results of this study indicate the high aerobic demand and the tremendous exercise intensity involved in the 2,000 meter RS.
