Abstract

Preceding the 1988 Olympic Games 6 elite female rowers were regularly subjected to an exercise test on a rowing ergometer (REM-test) with a time interval of about 5 weeks. Daily training volume was analysed in terms of rowed kilometres (RKM) and training time (TOTMIN, rowing and land training). The purpose of this study was to investigate the training volume during a season and to study possible changes in the working capacity of elite female rowers. The REM-test consisted of 3 consecutive blocks: 3 min warming up, 5 min standard load at anaerobic threshold and 2 min “all-out”. Blood lactic acid concentration (LA) was determined for the construction of a LA-power curve. The power at 4.0 mmol/1 (P4) was estimated as a measure of the aerobic capacity. The “all-out” score was used for calculating the maximal power (PM). Results show that both RKM and TOTMIN increase (range resp. 40-400% and 20-25%) when compared with the initial value. P4 also increases, in parallel with changes in both RKM and TOTMIN, with 8-10% of the initial value. PM increases continuously during the season up to 10% of its initial value. However, based on maximal heart rate and lactate values, it is concluded that PM was maximal in only 15% of the tests. Our data suggests that evaluation of training volume in elite female rowers is better done with P4 than with PM. The behaviour of P4 shows a parallel with the seasonal changes in the training load. PM does not behave as an indicator for maximal power, although its increase is of the same order of magnitude as the increase of P4.
